摘要： PURPOSE:To improve the propagation characteristic and the transmission impedance and to evade damage to the unit by providing a slot to each side wall of a metal carrier forming a gap and inserting both slots of a plate spring and bridging the gap. CONSTITUTION:A slot 30 orthogonal to a strip line 10 and opened at a side wall face is provided to each of a side wall 21 of a metallic carrier forming a gap 20. Then both side ridges of a plate spring 31A in the lengthwise direction are inserted to each of slots 30 opposite to each other to make the plate spring 31A in elastic contact onto the upper inner wall of the slot 30 thereby connecting both metallic carriers 6 electrically via a plate spring 31A. Thus, the gap between a conductor ribbon 11 and the plate spring 31A as a ground conductor is decreased, the production of the resonance in a transmission broad band is blocked to improve the propagation characteristic. Moreover, the size of the gap 20 is made narrow to improve the transmission impedance and no stress is exerted to a dielectric base 7 and the possibility of the damage to the dielectric base 7 is precluded.

摘要： PURPOSE:To make a beacon code image clear and to suppress masking, by constituting the title apparatus so as not to correspond to the radar radio wave by the side lobe of a ship's radar antenna approaching a radar beacon apparatus. CONSTITUTION:A level judge part 20 judges whether a receiving level is higher than a set level from a receiving radar pulse and, when the receiving level is higher, a signal held to a predetermined level is outputted for a definite period. A pulse width discrimination part 21 outputs the signal synchronous only to a radar pulse having either one of pulse widths longer and shorter than a set value. A radar level detection part 22 outputs the signal synchronous only to either one of a receiving radar pulse equal to or more than a set level in a receiving level and a receiving radar pulse equal to or less than the set level in the receiving level. A trigger signal generating means 23 outputs a trigger signal not responding to a receiving radar pulse, when the receiving level during a period wherein the output signal of the judge part 20 is held to a predetermined level is set level or less, having a pulse width when the pulse width of the receiving radar pulse approaches the set value or less but responding to other pulse.

摘要： PURPOSE:To improve restrictions on the parts composition and their mounting conditions and enhance the phase matching characteristics by furbishing a phase compensation circuit on the output side of a 2nd frequency conversion part of a signal receiver for each channel. CONSTITUTION:A signal fed to each channel is amplified by a low noise amplifier 1, passed through a band-pass filter 2, and fed to a 1st frequency conversion part 3. This RF signal is converted into a 1st IF signal with a 1st station originated signal distributed and supplied by a three-way divider 6. At this time, the channel DELTAAZch for the difference signal of azimuth angle and the channel DELTAELch for the difference signal of high-low angle are passed through devices (phase devices 7-2, 7-3, attenuator 8) differently from the devices where the channel SIGMAch for the sum signal is routed, so that the phase matching characteristics are deteriorated by temp. change. The 1st IF signal is converted by the 2nd frequency conversion part 4 into a 2nd IF signal with a 2nd station originated signal, which is distributed and supplied by another three-way divider 9, and is fed to a phase compensation circuit 5. Upon phase compensation there, the result is passed to the next stage. According to this constitution in which the phase matching characteristics can be compensated at the final stage, it is not required to constitute the three channels in the same manner.

摘要： PURPOSE:To obstruct the generation of a resonance in a transmission band of a wide area and to improve the propagation characteristic by providing a semicylindrical groove for bringing a semicylindrical spring to insertion/elastic contact on an opposed side wall of a metallic carrier, and providing a ground conductor right under a conductor ribbon. CONSTITUTION:Both metallic carriers 6 are connected electrically through a spring 31 in a position right under a conductor ribbon without being scarcely influenced by the working accuracy of a semicylindrical spring 31. Accordingly, an interval between a transmission line (ribbon 11) and a ground conductor (spring 31) can be made small as desired, the generation of a resonance in a transmission band of a wide area is obstructed, and the propagation characteristic is improved. Also, since there is nothing for obstructing to narrow the width of an interval 20 between adjacent microwave units 5, the gap width can be made small as desired until both side walls 21 nearly abut on each other. Accordingly, length of the ribbon 11 is shortened, and the transmission impedance is improved.

摘要： PROBLEM TO BE SOLVED: To improve the efficiency of integrated circuit design work by suppressing errors in selecting mounting objects in arranging and adjusting cells in integrated circuit design.
SOLUTION: An integrated circuit design support program, an integrated circuit design support device and an integrated circuit design support method design implementation by determining the identity and similarity of logical groups selected by specifying a range from a logical page, to classify the logical groups, creating an implementation pattern corresponding to each logical group beforehand, and arranging the implementation pattern corresponding to one logical group selected out of the classified logical groups, on an implementation diagram. When the additionally arranged implementation pattern overlaps with the already arranged implementation pattern in a region, the mounting pattern is dynamically deformed. An operation burden is thereby reduced, and integrated circuit design can be accurately and efficiently performed.

摘要： PURPOSE:To allow this system to tune a new frequency automatically and to implement proper date communication by switching sequentially the frequency of a local oscillating frequency switching means to the frequency of a radio wave of plural repeater stations, receiving the radio wave of a repeater station in an area where a mobile radio equipment itself is present thereon and sending the data at the frequency of the received radio wave. CONSTITUTION:While the frequency of an oscillation means of a mobile radio equipment 1 is switched sequentially to the frequencies fa-fd of a radio wave of plural repeater stations 2a-2d, the radio wave of the repeater stations 2a-2d in areas A-D where the mobile radio equipment 1 itself is present thereon is received. For example, when the mobile radio equipment 1 is resident in the area A, when the frequency of the local oscillation frequency switching means is switched to be the frequency fa, the radio wave from the repeater station 2a is received and the data of the mobile equipment is sent at the frequency fa of the received radio wave. Thus, the frequency of the oscillating means is automatically turned to the frequency of the repeater station in the area where the mobile radio equipment 1 is present thereon.

摘要： PURPOSE:To surely control an output level by reading a compensation data in the circuit operation which data has been written in advance before the operation of the circuit. CONSTITUTION:A detection means 20 detects the environmental condition such as temperature fluctuation and power voltage fluctuation and a control means 21 writes and reads the compensation data corresponding to the environmental condition by the detection means 20. The control means 21 receives an output of an amplifier 22 and an output of the detection means 20 before the actual circuit operation to write a compensation data in response to the environmental condition and receives only the output of the detection means 20 in the actual circuit operation to read the compensation data in response to the environmental condition in the circuit operation thereby making the output of the amplifier 22 constant. Thus, the output level is surely controlled without the effect of a transient response characteristic due to a pulse signal detection.

摘要： PURPOSE:To obtain an effective filter charactristic with the same size as a conventional converter by integrating a waveguide and a coaxial filter. CONSTITUTION:The coaxial filter 10 consists of an inner conductor 6 provided with a disk filter 5 coaxially and a dielectric 7 provided to cover the outer circumference of the inner conductor 6, the inner conductor 6 and the filter 5 are made of a copper or copper alloy, and the dielectric 7 is made by selecting a material having a desired dielectric constant among glass or 'Teflon(R)' or the like. The coaxial filter 10 is arranged in a form penetrating a prescribed guide wall of the waveguide 1. Thus, the same size as a conventional converter is adopted and excellent attenuation characteristic to a high band over the higher mode generating frequency or over is provided, then a radio wave trans mitted via the coaxial waveguide converter has an ideal transmission characteris tic whose band other than the operating band is cut off.
