Title: Directional coupler
Inventor: TAKANO TAKESHI
IPC: H01P5/18
Filed: 1978-09-12
Abstract: PURPOSE:To ensure the coupling over a wide range by using the dielectric substrate featuring a low dielectric constant at the center part of the coupling and also the dielectric substrate featuring a high dielectric constant at the both ends of the coupling respectively. CONSTITUTION:For the directional coupler, the coupling part between strip lines 11 and 12 is divided into center part C plus end parts E1 and E2. Part C is formed on substrate 13 featuring a low dielectric constant; while parts E1 and E2 are formed on substrate 14a and 14b each featuring a high dielectric constant. The coupling at the center part becomes dense since the number of the line of electric force going toward the lower part is decreased with increased number of the line of electric force going toward the lateral part. While for the coupling at the both ends becomes coarse since the number of the line of electric force going toward the lower part increases with decreased number of the line of electric force going toward the lateral part respectively.

Title: Fan motor rotation controller
Inventor: ISHIBASHI KOJI
IPC: H02P29/00
Filed: 1997-04-28
Abstract: PROBLEM TO BE SOLVED: To avoid malfunctioning of the rotation control of a fan motor and improve the safety and reliability thereof, by a method wherein a sensor circuit construction which does not rely upon only a revolution sensor attached to the fan motor is provided. SOLUTION: Current detection resistors R3 and R4 detect current values when fan motors 3 and 4 rotate and supply them to a protection circuit unit 10. When the fan motors 3 and 4 rotate, Zener diodes ZD1 and ZD2 in the protection circuit unit 10 are turned on and a thyristor SCR and a transistor Q are turned on. The collector of the transistor Q is connected to the input terminal 11e of a microcomputer 11, and binary signals in accordance with the current values from the current detection resistors are supplied to the microcomputer 11. The microcomputer 11 judges the rotation states of the fan motors in accordance with the binary signals as the rotation detection results and, rotation detection results from rotation sensors in the fan motors, and controls the supply of a power from a power supply circuit 1.  Therefore, the rotation of the fan motor can be detected securely, malfunctioning can be avoided and the reliability can be improved.

Title: Rotary heat exchanger
Inventor: INOUE SHIYUUICHI
IPC: F28D11/04
Filed: 1977-09-16
Abstract: PURPOSE: To clean and remove deposited materials adhered to heat source fluid at its rotating time by supplying the fluid for predeter-mined time to heat transfer tubes even afrer a motor for rotating a rotary heat exchanger is stopped.  
     CONSTITUTION: When a main switch 21 is closed, motor 8 and solenoid valve 20 are operated to rotate a rotary heat exchanger 4 to thereby start flowing heat source fluid through hollow heat transfer tubes 1. The heater 23 simultaneously increases its temperature to close a bimetal contact 24 after lapse of predetermined time and to maintain the same state. Impurities in the fluid are adhered and deposited on the inner wall due to centrifugal force in the tubes during operation. When the switch 21 is then opened, the motor 8 and the heater 23 are deenergized to stop the heat exchanger 4 to start cooling the heater 23. Since the bimetal contact 24 maintains closed state for prederermined time after the switch 21 is opened due to the waste heat of the heater 23, the valve 20 is energized to open. Thus, even if the tubes 1 are not rotated, water flows through the tubes 1 to thereby clean the deposited materials adhered to the tubes

Inventor: SUGIMOTO YOSHINAO
IPC: H01F30/00
Filed: 1992-04-30
Abstract: PURPOSE:To reduce transfer voltages to current transformers when a surge voltage intrudes from the terminal of a transformer. CONSTITUTION:Current transformers 28 and 29 are provided in a tank 21. Connecting lines 25 and 26 respectively connecting the coils of two transformers 23 and 24 housed in the tank 21 to the conductor 27 of a bushing 22 are passed through the current transformers 28 and 29. Then the cores of the current transformers 28 and 29 are earthed through earthing conductors 39 and 39. Since the cores of the current transformers 28 and 29 are earthed, the self- capacitances of the current transformers 28 and 29 are increased and, when a surge voltage intruded from the bushing 22 side is propagated through the earthing conductors 25 and 26, the transfer voltages to the current transfers 28 and 29 become lower.

Title: Pcm signal demodulator
Inventor: ODAKA KENTAROU
IPC: G11B5/09
Filed: 1977-09-20
Abstract: PURPOSE: To perform stable demodulation by turning OFF muting circuits only when the errors of the PCM signal at the demodulation cannot be corrected.  
     CONSTITUTION: The vertical synchronizing signal of the PCM signal reproduced with a VTR, etc. is separated by a separator circuit 21, by which the phase lock loop circuit PLL formed by a clock pulse generator 33, data synchronzing circuit 37, pulse generating circuit 36 is locked and the error detection of the PCM signal is accomplished by a CRC 23. When the CRC 23 detectes an error, the word having the error is corrected by interpolation of the words before and after the PCM signal having the error by way of mean value interpolation circuits 28L, 28R. If many of the errors detected by the CRC 23 occur owing to continuous drop-out, etc. and the word correction is infeasible, the muting contorl circuit 39 to which the error detection outputs of the CRC 23 are applied generates the conrrol signal to turn OFF muting switches 29L, 29R while the PLL is held locked even if the error detection signals disappear. Hence, repetition of ON and OFF, etc. of detrimental muting at the time of nustable playback mode, etc. does not occur and stable demodulation is performed
