The input terminal in which, as for 32, a wave enters in Drawing 7, the equal amplitude equi-phase power distribution unit with which 27 distributes an input wave to two outputs, The waveguide nonreflective termination machine with which 26 was provided in equal amplitude equi-phase power distribution unit 27, A phase power distribution unit and 33.34 are output terminals which at least the variable Phase shift amount phase converter which carries out the Transfer phase of the two outputs distributed with equal amplitude equi-phase power distribution unit 27 28.29, and the equal amplitude of 90 degrees which the output of phase converter 28.29 passes 30 are provided in equal amplitude 90* phase power distribution unit 30, and obtain output wave Vavb. In Drawing 6, 22 is a waveguide, the above-mentioned input terminal 32 is provided in one end, and the above-mentioned output terminal 33*34 is provided in the other end. The above-mentioned waveguide nonreflective termination machine 26 is formed in the upper part of the position of input terminal 32 slippage of this waveguide 22, and the above-mentioned equal amplitude equi-phase power distribution unit 27 comprises this portion. A hole for a pair of ferrite Toroid by which 23 was provided in waveguide 22, the lead for magnetization in which a pair of ferrite Toroid 23 let 24 pass, respectively, and 25 to let lead 24 for magnetization pass, and 31 are a pair of actuators for sending the current for phase control through lead 24 for magnetization. The two above-mentioned phase converters 28.29 are constituted by an above-mentioned pair each of ferrite Toroid 23, and the lead for magnetization. Phase power distribution unit 30 is constituted at least for the above-mentioned equal amplitude of 90 degrees by forming a slot in the common wall of waveguide 22. Next, operation is explained. The wave of the electric power A watt which entered from input terminal 32 is carried out by an equal amplitude equi-phase through equal amplitude equi-phase power distribution unit 27 for 2 minutes, and enters into phase converter 28.29, respectively.

[Problem(s) to be Solved by the Invention]

Since the conventional good transformation forcing allocation machine is constituted as mentioned above, when frequency is low, in proportion to a wavelength, the whole device becomes large. In order to enlarge change of Phase shift amount especially to amplitude permeability change of a ferrite, making the height of phase converter 28.29 low has restriction from the conditions which must make regularity the ratio of two ratios of the height of ferrite Toroid 23 and hole 25, and thickness of ferrite Toroid 23. When frequency is low, in a waveguide, since a section size becomes large, an external connection circuit is a coaxial track in many cases, and a coaxial waveguide converter is needed. For this reason, there is a problem that it is difficult to constitute the whole good transformation forcing allocation machine superficially. On the other hand, if it is going to use semiconductor devices, such as a diode, for phase converter 28.29 for plane composition, the problem it becomes impossible to bear the increase and high electric power of a loss by resistance of a semiconductor will arise. One electronic actuator 31 per phase converter is [ a ferrite and phase converter 28.29 using any of the semiconductor ] needed. For this reason, there is a problem which must control two actuators 31 to use that whose characteristic corresponded for two phase converters 2B and 29 and each actuator 31 in order to make the phase of two output terminals 33.34 regularity, and also to keep (thetaa+thetab) constant. Although a quick electric power variable speed is obtained by electronic actuator 31, when the speed of a variable speed is not required, there is a problem to which the cost to the function of electronic actuator 31 becomes high rather. There were various subjects which were mentioned above in the conventional good transformation forcing allocation machine. The object of the present invention is as follows. Be made in order to cancel the above subjects, and it has low loss and electric power-proof [ high ] performance, and carry out plane composition. By one actuator, even if you change an electric power ratio, obtain a good transformation forcing allocation machine which can make regularity a phase of a wave which appears in two output terminals.

[Means for Solving the Problem]

Drawing 2 shows the relation between 1st and 2nd lozenge dielectric boards 1.2 that constitute phase converter 6.7, and straight line conductors 3a and 3b. In Drawing 2, straight line conductors 3a and 3b are arranged by between distance. The length of diagonal line 1a which intersects perpendicularly with the straight line conductor of 1st lozenge dielectric board 1 is chosen as 2D. By this, one peak IC (or ld) of a lozenge is straight line conductor 3a (or 3b). - When I do, it has accomplished so that the above-mentioned diagonal line 1a and diagonal line 1b which intersects perpendicularly may be in agreement with straight line conductor 3b. Length B of the above-mentioned diagonal line 1b is chosen so that the phase contrast of phase converter 6.7 may be 90 degrees at this time. Next, operation is explained. It is Lal about the length to which 1st lozenge dielectric board 1 in phase converter 6 covers straight line conductor 3a in Drawing 2, the length which is not covered with L a 2- and each dielectric board in the length to which 2nd lozenge dielectric board 2 covers straight line conductor 3a -- La3 -- if an acoustic phase coefficient is set to beta1.beta2.beta3, respectively, insertion phase thetaa of this phase converter 6 will be given with a following formula. theta a-beta 1, La1 Samurai beta2, La2+beta3, and La3 ..................

(4) It is LO1 straight-line conductor 3a about the full length of straight line conductors 3a and 3b. When the length of diagonal line 1b of 1st lozenge dielectric board 1 parallel to 3b is set to B, there is a relation of a following formula from the determination conditions of this diagonal line 1b.

((beta1-beta3) -La1) aomegaV b = pios exp (j C/2) ............... actuator 10 of changing Lal from OD above-mentioned type 0IIIl and 00, i.e., one piece, -- the -- the [ 1. ] -- an electric power distribution ratio is changeable by moving lozenge dielectric board 1.2 of two in the direction of arrow a. Even if it changes an electric power distribution ratio, the phase of the wave which appears in output terminal 33.34 is eternal. According to the above, since there are not a magnetic body product of a ferrite, resistance of a semiconductor, and influence of the amplitude-limiting effect, the low-loss characteristic and electric power-proof [ high ] performance can be got, and plane composition can be carried out. 71 and 2nd lozenge dielectric board 2 are straight line conductors 3a about the impedance of the portion into which 1st lozenge dielectric board 1 covers straight line conductors 3a and 3b in phase converters 6 and 7. If impedance of the portion which is not covered with 22 and each dielectric board in the impedance of the portion which covers 3b is set to 23, and Zl is a value near 23, it will become reflection is small and unnecessary [ 2nd lozenge dielectric board 2 ], but reflection will become large if Zl differs from 23 greatly. in this case -- if Z2 is made into the value of a following formulas and the conditions of the above-mentioned formula (7) are fulfilled, 2nd lozenge dielectric board 2 will work as 1/4-wave impedance Transformer -- reflection -- non-waste -- things are made. Z2=5Postcode]Postcode Zero person Although the case where 2nd lozenge dielectric board 2 was arranged around 1st lozenge dielectric board 1 was shown in Drawing 1, Processing and an assembly will become easy if 1st lozenge dielectric board 1 of necessary thickness is formed by sticking another lozenge dielectric board which has the same outside as 1st lozenge dielectric board 1 in 2nd lozenge dielectric board 2 as a manufacturing method of these lozenge dielectric boards. Here where good transformation forcing allocation machine 11*12.13.14 by this invention and the good transformation forcing allocation circuit used combining six 15.16 are shown in Drawing 3 shows the case where electric power composition of a maximum of four amplifiers 17.1B and 19.20 is performed. In this circuit, electric power can be distributed and compounded by an equal amplitude equi-phase only to the amplifier connected by adjusting the electric power distribution ratio of a good transformation forcing allocation machine. For this reason, the work which adds the number of an amplifier to three pieces from two pieces, and the work which exchanges the broken amplifier can be done, keeping an output electric power level constant without being accompanied by power loss. In Drawing 3, it is 1.IIAA2'4'4' 2 *. Values, such as A, show each track or the passage electric power of the terminal. In this case, all the good transformation forcing allocation machines 11~16 are in the state of Equal power distribution. To. In such a case, it is necessary to drive each phase converter 6 and 7 so that good transformation forcing allocation machines 11 and 16, good transformation forcing allocation machines 12 and 14, and good transformation forcing allocation machines 13 and 15 may become the respectively same electric power distribution ratio. using track 21 which intersects a part of track which accumulates good transformation forcing allocation machine 11~16 on Drawing 5 in layers, constitutes it in it, and connects between each good transformation forcing allocation machine 11*16 to it -- the [ of good transformation forcing allocation machine 11~16 of each above ] -- the [ 1. ] -- what carried out actuator 10 of lozenge dielectric boards 1 and 2 of two in common is shown. Although six actuators are originally needed since six good transformation forcing allocation machines 11~16 are used, crossing track 21 -- good transformation forcing allocation machines 11 and 16, good transformation forcing allocation machines 12 and 14, and good transformation forcing allocation machines 13 and 15 -- since the move direction of lozenge dielectric board 1.2 of the phase converter of each group is made the same, actuator 10 can be used in common and the number of actuators 10 can be reduced to three pieces.

[Effect of the Invention]

as mentioned above -- since two Phase shift amount variable phase converters in a good transformation forcing allocation machine were constituted from two Triptych rate type strip tracks which cover two straight line conductors in common with the dielectric board of a lozenge according to this invention Even if plane composition can be performed and also it changes an electric power ratio by one actuator, there is an effect which can make regularity the phase of the wave which appears in two output terminals. It is if it accomplishes so that the 2nd lozenge dielectric board may be loaded in the circumference of the above-mentioned lozenge dielectric board, A reflective damping characteristic is easily improvable, further, multiple good transformation forcing allocation machines by this invention are accumulated in layers, and a good transformation forcing allocation circuit is constituted, The actuator of the lozenge dielectric board of each good transformation forcing allocation machine is carried out in common using the track which intersects connection of the part between each good transformation forcing allocation machine, Electric power composition of a plurality of amplifiers can be performed by a number smaller than the number of good transformation forcing allocation machines of actuators, and an overall dimension can be made small, and the effect of being able to lower cost is acquired.
