Title: Plasma coupled device driving pulse
Inventor: KUSUDA YUKIHISA
IPC: H01L29/74
Filed: 1983-08-10
Abstract: PURPOSE:To curtail OFF-state time, and to enhance the speed of a plasma coupled device by a method wherein the low level voltage of driving pulses is set to a negative voltage, and electron-hole plasma is absorbed utilizing a depletion layer between the emitter and the base thereof. CONSTITUTION:The figure shows the waveform of driving pulses, while the low level voltage thereof is set to a voltage lower by VphiM than 0V (a collector voltage). Because the driving pulse low level voltage is set to -VphiM, width Xd1 of a depletion layer generated at this time becomes to a specified value. Width Xd1 can be enlarged by enlarging the voltage VphiM, and the considerable part of a plasma region 5 can be covered. Accordingly, the fair part of generated plasma can be swept out according to an electric field, therefore OFF-state time of a conductance transistor CDT is curtailed, and speeding up of a plasma coupled device PCD can be attained. The larger voltage VphiM is set, the more it is favorable, while it is necessary to give attention to that a limination is applied according to the reverse withstand voltage of the CDT. Moreover, to change the construction of the device is not necessary in this method, and this method is only improvement of the application method of the driving pulses.

Abstract: PURPOSE:To eliminate a key input operation error by providing a display means for discriminating a key or a group of keys, which is possibly to be pushed next in the operation of a program, from other keys. CONSTITUTION:When a relay ladder circuit diagram (wherein an upper ladder circuit is decomposed into circuit elements corresponding to symbol keys in a lower figure) is to be programmed, the lamps of two branch part keys turn on in a step STP1, but a branch to only an X1 is caused firstly, so an operator pushed a key indicated in an STP2 (OP). In an STP3, the lamp of a key for connection between two contacts and one connection line turn on. Therefore, the operator OP pushed a key for a contact (a) because the X1 is the contact (a) in an STP4. In an STP5, an R, an X and a Y turn on for specifying the input kind of the contact (a). In an STP6, a key X is pushed. A numeric key is then turned on, so a key 1 of the X1 as a (STP7) is pushed (STP8). Thus, key input operation is completed similarly.

Title: Radio relay system
Inventor: YOKOTA TAKAHIRO
IPC: H04W16/24
Filed: 1981-09-17
Abstract: PURPOSE:To reduce both the beat disturbance and a cost for a radio system having overlapping service areas, by using the oscillating source outputs modulated by the different low band frequencies to the carrier wave for each repeater station. CONSTITUTION:A radio system has overlapping service areas through >=2 repeater stations. For such radio system, the output to be modulated given from an oscillator 1 which received the modulation of frequency with the low band frequency sent from a low band noise frequency oscillator 2 is treated as the carrier wave for each repeater station. Thus the frequencies of the carrier waves of >=2 repeaters are modulated and vary independently of each other. This prevents the occurrence of a certain beat. A medium degree of stability is sufficient for the oscillator 1 which serves as an oscillating source of the carrier wave.
