Title: Measuring device for attenuated quantity of microwave
Inventor: HIROYA HIKARI
IPC: G01R27/28
Filed: 1979-01-19
Abstract: PURPOSE: To continuously and accurately measure the attenuated quantity of an object which has a wide dynamic range as to the attenuated quantity, by providing a microwave attenuation measuring unit with a timer to intermittently operate a PIN modulator.  
     CONSTITUTION: A relay 12 provided on the input side of a comparison amplifier 8' and another relay 11 provided on the control current input side of a PIN modulator 5 are opened or closed in connection with a timer 10. For example, the relays 11, 12 are closed for several seconds per sixty seconds to operate the PIN modulator 5. A capacitor C is loaded on the input and output of an operational amplifier 14. When the relay 12 is closed, comparison with a reference voltage 15 is effected and a measured value determined by resistors R 1 , R 2  is picked out. When the relay 12 is opened, an original value stored in the capacitor C is picked out. As a result, the comparison amplifier 8' is provided as a holding circuit and can maintain an output to a display circuit 13. Thus, there is no attenuated quantity fluctuation in a measuring system even if an attenuated quantity with a dynamic range from 0dB to 70dB is continuously measured for more than a month. Therefore, accurate measurement is enabled.

IPC: H01L23/48
Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To perform inner wiring connection of a terminal for a signal in a short time. SOLUTION: A lead pin 7 of the terminal for a signal is held with a signal terminal block 6, which is held with an envelope case 3. The lead pin 7 has a flexed part 7a between a part on which the lead pin 7 is held and the tip part 7a in a package. When the envelope case 3 is mounted on a metal base plate 9, the lead pin 7 whose free length L1 is set longer than a compressive length is compressed before mounting and always presses a circuit board. The lead pin 7 has a structure, wherein the lead pin 7 presses the circuit board and comes into contact with it by the self spring effect, so that a process like soldering in a bonding part can be dispensed with. Since bonding of the lead pin 7 and the circuit board is completed simultaneously with the mounting of the envelope case 3, the assembling time of the package can be reduced.

Title: Compound compressor
Inventor: NOZAWA SHIGEKAZU
IPC: F04B49/00
Filed: 1978-01-23
Abstract: PURPOSE: To maintain a highly efficient operation constantly by providing two motors to a single compressor for obtaining high efficiency by driving two motors in a high load and a single motor in a low load.  
     CONSTITUTION: Driving motors 1 and 2 are arranged to the both ends of a compressor 3. As for the driving characteristics of the motor group thus arranged, motors 1 and 2 are given an equal output and the half of the capacity of the compressor. Consequently, the motor efficiency for the load can be found in the graph. That is, a curve "a" shows the efficiency of two-motor operation, while "b" shows that of a single motor. When the load is 100%, two motors are desirably operated. When the load is reduced on the curve "a" down to 75%, the curves "a" and "b" are crossed at a point "c". Therefore, a highly efficient operation can be maintained by driving two motors above 75%, and a single motor under 75%.
