Title: Gate control circuit of gto thyristor
Inventor: KOBAYASHI TADAO
IPC: H02M1/06
Filed: 1983-08-03
Abstract: PURPOSE:To eliminate the influence of a noise without necessity of other power source and an amplifying circuit by utilizing ON and OFF command signals themselves as ON and OFF gate current sources of a GTO thyristor. CONSTITUTION:When an ON command signal is applied to a transformer TF1, an output is generated at the secondary side, a base current is supplied through diodes D3, D4 to a transistor SW1, thereby turning ON the SW. Then, the ON gate current is supplied to between the G and K of a GTO thyristor through diodes D1, D2 and the SW1. Simultaneously, when the OFF command signal is applied to a transformer TF2, an OFF gate current is supplied from the secondary output through a transistor SW2 and diodes D5, D6 from a transformer TF2 to the K and G of the thyristor.

Filed: 1985-06-28
Abstract: PURPOSE:To improve image quality and the reliability of a machine body and to extend the life of the machine by successively counting the number of image forming operations and displaying the need of a periodic inspection when a set value or above is attained. CONSTITUTION:A microcomputer 501 reads out data from a region 506b of an external memory 506 and adds a '1' thereto and writes the result as the fresh present value again into the region 506b at every one execution of the copying operation. The microcomputer displays the sentence 'contact service engineer for periodic inspection' on the 1st display part 39. This display is made only during the time since the turning on of a power supply till the end of warming up. The display can be made in the stage of the next periodic inspection by providing a means to allow the service engineer to rewrite the present or set value in the memory 506. The sure maintance and inspection are thereby executed and the improved image quantity and machine reliability and extended life are resulted.

Title: Constant voltage circuit for semiconductor integrated circuit
Inventor: MATSUYAMA TOSHIYUKI
IPC: G05F1/56
Filed: 1986-06-18
Abstract: PURPOSE:To prevent an output transistor (Tr) from breaking down by providing a Tr which is interposed between a power source input terminal and an output terminal to detect a reverse bias being impressed or the output Tr which controls an output and then short-circuits the output terminal. CONSTITUTION:The output Tr1 is so controlled that the voltage V0 at the output terminal 12 is a set voltage. If a source voltage VIN drops owing to a break of power supply, the emitter voltage of the output Tr1 rises above its base voltage because there is a capacitor CL at the output terminal 12, and a reverse bias is applied, so that the Tr breaks down possibly. A Tr3 turns on at the time of the application of said reverse bias and grounds the capacitor CL to discharge its electrostatic charge. Consequently, the reverse bias is eliminated and the output Tr1 is prevented from breaking down.

Filed: 1991-05-20
Abstract: PURPOSE:To remove the misrecognition of a message as a different message or a continued message and to improve operation convenience by a user by accurately informing the delimitation of messages an surely transmitting the contents of each message. CONSTITUTION:A selective call signal from a base station which is not shown in the figure is received by a radio circuit 2 through an antenna 1 and transmitted to a demodulator circuit 3 to demodulate the signal and the demodulated signal is applied to a control circuit 40. The circuit 40 reads out the identification (ID) information of its own receiver which has been previously stored in an ID-ROM 5 provided to the circuit 40 and compares ID information included in the selective call signal with that of its own receiver by an information extracting means 41 built in the circuit 40. When the contents of both the information match with each other, the circuit 40 decides the existence of a call to its own receiver and applies a call information signal to a speaker 7 through a driving circuit 6 to generates a calling tone. Thus the circuit 40 is allowed to act as an ID information match detecting means 42 and functioned also as a display control means 43 by correcting an error in a decoded message code and then corrected code is sent to a display driving circuit 8.
