摘要： PURPOSE:To perform independent and centralized measuring, collecting and output processing of traffic by separating it from a switching board body, by providing a processor dedicated to traffic measurement and a dedicated external circuit. CONSTITUTION:Monitor test control processor STC2-1 sends a request for traffic information to an optional control processor or optional network control processor by a traffic collecting output program and then collects traffic data from common memory 7 and individual memories 3-2, 4-2, 5-2, and 6-2 of respective processors. Further, STC2-1 sends a false call to main switchboard 1, which returns an IRT acquition end signal to STC2-1; and a timer for delay time measurement counts the time to measure an input-output response delay time, and a selective number is also sent out to count the time until a start signal is received, thereby measuring a switching delay time.

摘要： PURPOSE:To increase the directional control range of the antenna for the mobile antenna device which is used for the satellite communication, by selecting the bend angle to those values other than 90 deg. for the beam which forms the beam wave guide. CONSTITUTION:Ducts 42 and 43 combined together with bearing 44 are attached to car body 21 or the like via bearing 45. These bearings 45 and 44 are located so that angle alpha may be formed between their center axes 13' and 14', and at the same time angle beta is formed between axis 14' and mirror axis 54 of the main reflector each. Then the beam wave guide is formed with a primary radiator 27, curved reflector 48 and plane reflector 49 each; and the beam is radiated along axis 54 and with formation of angles alpha and beta. Here if angle alpha is set smaller than 90 deg. with angle beta set larger than 90 deg. respectively, reflector 26 is turned upward to increase the angle at which reflector 26 hits duct 42 or driving part 53 and others. Thus the mobile range can be increased. Furthermore, the undesired control region lower than the horizontal direction can be eliminated, thus increasing the wave angle.

摘要： PURPOSE:To facilitate an easy convertion of polarized wave types, by connecting a polarized wave converter which is capable of a phase transition between 90 deg. and 180 deg. to the inside of an electromagnetic horn having the aperture parts of asymmetric rotation and thus compensating the phase transition caused at the inside of the electromagnetic horn. CONSTITUTION:The rotatable flanges 11, 12 and 13, polarized wave converters 14 and 15 which performs a phase transition between 90 deg. and 180 deg. plus a rectangular/round converting waveguide 16 are connected to the throat part of an oval aperture horn 1 as shown in the diagram. The circular polarized wave arrived at the aperture surface I2 is turned into an oval polarized wave owing to a phase difference between the X2 and Y2 axes of the horn 1 and then put into the converter 14. The converter 14 is rotated to obtain a point where a linear polarized wave is obtained through the flange 12, and then the converter 15 is rotated to obtain a linear polarized wave on the end surface O2 and in a desired direction. The linear polarized wave arrived at the surface I2 is also turned once into an oval polarized wave, and a linear polarized wave can be obtained on the surface O2 just by rotating the converters 14 and 15. As a result, the polarized wave type can be converted in a simple way just through rotation of the polarized wave converters even in case when the electric wave is transmitted.

摘要： PURPOSE:To radiate the full energy of transmitting and receiving waves, by connecting a 90 deg. polarized wave transducer equipped with a rotary flange, to the input and output terminals of the elliptical opening horn, and connecting a circular-rectangular converting waveguide to the other end of the transducer through the rotary flange. CONSTITUTION:In case when a wave coming into the input face I2 of the primary radiator is a circular polarized wave, the wave passing through the elliptical horn 10 is input to the polarized wave transducer 12 as an elliptical polarized wave since the phase difference is caused between the X2 axis and the Y2 axis of this horn 10. In this case, if the phase-shifting amont of the transducer 12 is about 90 deg.; irrespective of the circular polarized wave factor of an elliptical polarized wave which is input, when the transducer 12 is being rotated, an angle becoming a linear polarized wave at the place of the rotary flange 13 is made. When the circular-rectangular converting waveguide 14 is rotated through the rotary flange 13, there is no loss caused by mismatching of a wave, and all the full-wave energy can be output to the output terminal 02. On the other hand, in case when a wave coming in is a linear polarized wave, it is converted to an elliptical polarized wave and is input to the trasducer 12, therefore there is no less caused by mismatching of a wave, and the adjustment for outputting to the output terminal 02 becomes possible by all the same operation.

摘要： PURPOSE:To enable tracking without crosstalk to an arbitrary arrival polarized wave, by supplying a reference signal and an error signal led out from dextro- rotary/levo-rotary circular polarized wave components to a tracking receiver. CONSTITUTION:An arrival radio wave is received by a radiator 11 and higher- order mode outputs TE01, TM01 are taken out by couplers 12, 13 while error signals VH, VE due to dextro-rotary/levo-rotary circular polarized wave components are taken out by a hybrid 15. The higher-order mode outputs are converted to orthogonal outputs EX, EY through 180 deg./90 deg. phase shift type polarizers 16, 17, a polarization wave divider 20, low noise receivers 21, 23 and directional couplers 22, 24. The outputs EX, EY are converted through an orthogonal polarization wave divider 25, an 180 deg. polarizer 26 and a polarization wave divider 27 while the converted outputs are synthesized by a hybrid 28 and the synthesized output is converted to a reference signal through an orthogonal polarization wave divider 29, phase shifters 30, 31, 35 and an orthogonal polarization wave divider 36 to be supplied to a tracking receiver along with the error signals.

摘要： PURPOSE:To improve performance by providing a skirt around an auxiliary reflection mirror so that reflection effects may be given in a low frequency band and shielding effects on the main reflection mirror aperture face may be reduced in a high frequency band. CONSTITUTION:Auxiliary reflection mirror 2 and skirt 4' are arranged coaxially in the center area and the outside circumference area respectively. Though auxiliary reflection mirror 2 is formed by a metallic reflection face, a metallic face or a metallic film provided with plural round holes whose diameter is selected to be longer than the half value of the free space wave length of a high frequency out of two frequency bands and be shorter than the half value of the free space wave length of the low frequency is used as skirt 4'. As a result, the cut-off frequency for electromagnetic waves of holes can be utilized to transmit electromagnetic waves of the high frequency through holes while holding shielding effects for electromagnetic waves of the low frequency.
