Title: Pulse modulator
Inventor: TAKIGUCHI NOBORU
IPC: H03K3/53
Filed: 1989-01-23
Abstract: PURPOSE:To obtain a pulse modulator which follows the change of PRF and sets a transmission mean power constant by detecting the change of PRF in a pulse mean value circuit and controlling a charge voltage for a pulse forming circuit. CONSTITUTION:When a pretrigger changes for moving target display MTI, it is inputted to the mean value circuit 12, and outputted as a DC voltage following to PRF. On the other hand, the voltage charged from a high voltage power source 1 to the pulse forming circuit 6 is converted into a low voltage by a voltage-dividing resistor 4, inputted to an addition circuit 13 and inputted to a subsequent trigger generation circuit 11 by adding the output voltage of the mean value circuit and the charged voltage to it. In the trigger generation circuit 11, an internal reference voltage is compared with the output voltage of the addition circuit 13. When it exceeds the reference voltage, a trigger pulse is supplied to a switching element 10. Consequently, the switching element 10 is conducted, and the secondary side of a charging transformer 2 is short- circuited, whereby charge from the high voltage power source is stopped. Thus, the mean output power of a transmission tube can be set constant.

Title: Vtr antenna input distributing circuit
Inventor: IGARASHI MASASHI
IPC: H04N5/44
Filed: 1987-01-23
Abstract: PURPOSE:To prevent a picture in a TV receiver screen from going to irregular due to channel selection through the tuner of a VTR by providing a buffer amplifier between a VTR tuner terminal and the distributor of the titled circuit which outputs an antenna input partly to a VTR tuner terminal and partly to a VTRF terminal. CONSTITUTION:One end of the distributor 5 is connected to the VTR tuner terminal 7 via the buffer amplifier 14 and a filter 6, so that an antenna input distributed by the distributor 5 is outputted to the terminal 7 via the buffer amplifier 7. With such constitution, selecting operation through the tuner of the VTR connected to the VTR tuner terminal 7 does not influence the distributor 5 even if the output impedance of the terminal 7 becomes lower in relation to a tuning frequency signal received by the TV receiver. As a result, even if a selection operation is achieved through the tuner of the VTR, the level of a tuning frequency signal in the antenna input that is outputted to a VTR terminal 13 is kept constant, hence no irregularity appears in the picture of the TV receiver.

Abstract: PURPOSE: To process signal in a high speed by low-speed processing micro computers, by causing plural micro computers to share the processing of serial signals with one another.  
     CONSTITUTION: Clock CL p  from clock generator circuit 3 is converted to a binary signal and is applied to si terminals of micro computers μ CPU1 and μ CPU2, and clocks CLa and DLb different in phase from circuit 3 are applied to sc terminals of μCPU1 and μCPU2.

Though CLa and CLb have a period two times as long as CL p  and binary signal p is synchronized with CL p , it is sufficient if each  micro computer is operated in the half speed of signal P, so that low-speed micro  computers can share the processing of setial signals with one another.
