Patent JP-S5772437-A (JP)
Title: Infinite phase shifter
Inventor: MIYAMOTO BUNICHI
IPC: H03H11/16
Filed: 1980-10-22
Abstract: PURPOSE:To obtain control signals from outputs of the first phase detector, which obtains a beat output between the output of a voltage controlled oscillator and that of a sine wave oscillator, and the second phase detector which obtains a beat output between the output of a 90 deg. phase shifter and that of the voltage controlled oscillator. CONSTITUTION:When a phase difference is generated in an IF signal to change the level in the input of an automatic phase control (APC), a frequency (f) of a voltage control oscillator VCO is changed in accordance with the magnitude and the polarity of this change to generate frequency diffrence DELTAf=f-f'. This DELTAf is converged to zero approximately finally by the operation of the APC system and a frequency discriminator FD, but the speed of this operation is low sufficiently for the change of the APC input; and consequently, control signals ix+, ix-, iy+, and iy- in orthogonal phase relations having the same frequency as DELTAf and constant amplitudes are outputted during this convergence and are applied to a phase shifting part SHT of an infinite phase shifter. The first phase detector PD1 takes out a beat output corresponding to the phase difference between frequencies (f) and f', and the second phase detector PD2 takes out the phase difference between the frequency (f) and the f' shifted 90 deg. in phase.

Title: Power supply circuit
Inventor: NAKAMURA TAKESHI
IPC: G05F1/56
Filed: 1989-06-09
Abstract: PURPOSE:To simplify the constitution of a power supply circuit and at the same time to use the power circuit as an AGC circuit or an ACL circuit of an oscillation circuit by using the 1st and 2nd regulators and a transistor whose base is used as a control terminal. CONSTITUTION:A 1st regulator 12 contains an input terminal 18 and an output terminal 20, and a 2nd regulator 22 contains an input terminal 28 and an output terminal 30 respectively. When the voltage is applied to both terminals 18 and 28, the output voltage is obtained via both terminals 20 and 30. Under such conditions, the value of the voltage inputted to the base of a transistor TR 14 which serves as a control terminal is changed. Thus one of both output voltage increases with the other decreasing or vice versa. As a result, the value of the output voltage can be controlled by changing the value of the voltage inputted to the control terminal. Then the constitution of a power circuit can be simplified, and the power supply circuit can be used as an AGC circuit or an ALC circuit of an oscillation circuit.

Title: Detecting and display device for electricity conducting state
Inventor: TSUJI TATSUO
IPC: G01R19/145
Filed: 1980-10-21
Abstract: PURPOSE:To display an electricity conducting state easily by detecting the presence or absence of the electric current flowing in a main electricity conducting circuit for the purpose of conducting electricity to apparatus and displaying the same. CONSTITUTION:If a circuit switch 1 is closed and electricity is conducted to load 2, electric current flows in a bus 7, and a detecting winding 8 detects this and transmits a signal to an amplifier 10. The transmitted current signal lights a lamp 11, thereby indicating that the circuit is in the state of a electricity conducting. At the same time, it operates a relay 12 to feed a switching signal for remote display to the outside. A transformer 9 converts the voltage of the bus 7 to the voltage sufficient for operating the amplifier 10, the lamp 11, and the relay 12 and supplies electric power. Then, the flow of load current in the used plug socket, etc. is displayed in spite of absence of an electricity conduction display circuit in apparatus, and the neglection in switching off is prevented.

Title: Scroll compressor
Inventor: SUGAWA MASAAKI
IPC: F04C18/02
Filed: 1990-06-06
Abstract: PURPOSE:To prevent liquid refrigerant from being heated due to heating of motors and also from being dropped from a motor chamber side to an oil sump in returning liquid with use of a shielding plate by covering a recessed portion provided on a frame intercommunicated with a fixing scroll suction side with the shielding plate. CONSTITUTION:Refrigerant allowed to flow from a suction chamber 15 to the inside of a shell 13 is shielded by a shielding plate 19 not to flow to motor sides 10 and 11. The refrigerant in then sucked directly from a recessed portion 18 to a suction port 2c provided on a fixing scroll 2, and is compressed by the scroll action. Accordingly, the refrigerant gas is not heated by heating of motors 10 and 11, and therefore, it is possible to reduce heating loss and improve the efficiency. The shielding plate 19 can separates a compressing mechanism 14, the motors 10 and 11 and oil sump from each other. Consequently, in starting, the inner pressure on the motor side downwardly from the shielding plate 19 is difficult to be reduced, thus suppressing the forming. Furthermore, is being subjected to the forming, it is suppressed by the shielding plate 19 which causes oil not to flow in the suction port 2c, thereby preventing the oil pressure from being released to the outside of the compressor.

Filed: 1990-06-05
Abstract: PURPOSE:To form source and drain regions while preventing hydrogen from reaching the gate insulator-semiconductor interface by providing a protective insulating film that is thicker than the projected range of hydrogen ions. CONSTITUTION:A thin-film transistor includes a substrate 201, on which a gate electrode 202, a gate insulator 203, a thin amorphous silicon film 204, and a protective insulating film 205 are deposited.
