IPC: H04N11/00
Filed: 1986-09-19
Abstract: PURPOSE:To simplify a system by respectively providing converting functions in transmitted digital and analog signals so as to synchronously superpose a synchronizing signal on a G signal at the time of transmitting the synchronizing signal on a master machine and separating the synchronizing signal from the signal synchronously superposed on the G signal so as to supply to a display monitor on a slave machine. CONSTITUTION:The master machine is constituted with an RGB transmission converting unit (converter) 14 where the digital signals from a computer 11 are supplied, a video signal demodulator 16 which converts a composite color video signal from an AV equipment 15 into an RGB signal synchronously superposed on the G signal and a transmitting master unit 18. Meanwhile, the slave machine is constituted with a slave unit 17 which is a console unit and the display monitor 12 connected to the unit 17 with a leased RGB cable 19. And the slave unit 17 has an input/output bridge terminal 13 of the RGB signal. Thus the wiring of the slave unit (AV equipment) and the display monitor on the slave machine side need not be provided individually, so that the wiring can be carried out with one RGB cable.

Title: Semiconductor integrated circuit
Inventor: ARIMURA KENICHI
IPC: H03K17/30
Filed: 1983-11-28
Abstract: PURPOSE:To detect a variation of a current amplification rate of transistors (TRs) and temperature fluctuation by forming four TRs of the same polarity on a semiconductor substrate and connecting them to a differential circuit in a form of Darlington. CONSTITUTION:TRs Q1-Q4 of the same porality are constituted on the semiconductor substrate. Each collector and each base of the TRs Q1, Q2 are connected respectively, the TRs Q3, Q4 are connected in a form of Darlington while the Q3 is used as the post-stage, and the base and collector of the TRQ4 are connected. The collector of the TRQ1 is connected to a current source 1 and the collectors of the TRs Q3, Q4 are connected to a current source 2. Emitters of the TRs Q2, Q3 are grounded and connected differentially and the TRs Q1, Q4 form a differential circuit where the bases are used as inputs. When current sources 1, 2 are the same, the emitter current and the base-emitter voltage of the TRs Q1, Q2 and Q3 are identical, and the emitter current of the TRQ4 is a value being one over a current amplification factor hFE of the TRQ3. Thus, a voltage difference between input terminals 3, 4 is generated as a function of the hFE of the TRQ3, the variance in the hFE and temperature fluctuation are detected accurately.

Title: Ac power supply
Inventor: MUROYAMA SEIICHI
IPC: H02M5/297
Filed: 1988-09-07
Abstract: PURPOSE:To contrive to miniaturize an apparatus and lower its noise by generating a signal synchronized with a high-frequency AC voltage on the basis of a PWM signal and by controlling the operation mode of a polarity switching circuit through said synchronized PWM signal. CONSTITUTION:A high-frequency power circuit 10 is controlled from a reference oscillator 31 via a driver circuit 34. A pulse width modulation signal generator circuit 32 generates a pulse width signal. A synchronizing PWM generator circuit 36 is composed of J-K flip-flops 36-1, 36-2 and outputs a PMW signal Vc synchronized with a high-frequency AC from a reference oscillator 31 inputted via a terminal Va. If the operation mode of a polarity switching circuit 20 is controlled by said PMW signal Vc via a logical circuit 33 and a driver circuit 35, no mode switching is conducted in the middle of a voltage e1, because a high-frequency AC voltage e1 also changes when said operation mode changes between a passing mode and a synchronous rectification mode.
