Patent JP-H0377491-A (JP)
Title: Frequency interposer
Inventor: JIEIMUZU JIYON GIBUSON
IPC: H04N7/06
Filed: 1990-08-10
Abstract: PURPOSE: To secure the interleave between the video signals and auxiliary signals by distributing the auxiliary signals to the 1st and 2nd signals which are exclusive to each other in response to a horizontal synchronizing signal to invert the partial polarity of both signals and performing the rectangular phase modulation in response to the 1st and 2nd signals and the horizontal synchronizing signal. CONSTITUTION: The binary auxiliary signals supplied from a digitizing circuit and a processing circuit 28 are applied to a spectrum adjustment circuit 30 which concentrates the energy of received signals at a spectrum band having its center at a place equal to 1/2-odd times as high as the line frequency. A multiplexer 301 distributes the auxiliary signals to two intermediate signals including the parts which are exclusive to each other. Then the polarity of the exclusive parts of the auxiliary signals are inverted by the 1H delay elements 302 and 303 and the subtracters 304 and 305. The multipliers 306 and 307 perform the rectangular phase modulation for the carriers having frequency of a multiple to the line frequency of a video signal. The output signals are totaled by an adder 308 and supplied to a modulator 32.  As a result, the side band of an auxiliary carrier is conditioned to occur between the spectrum bands which are occupied by the luminance components.

Title: Protective circuit for transistor bridge
Inventor: OKATSUCHI CHIHIRO
IPC: H02H7/12
Filed: 1989-08-17
Abstract: PURPOSE:To manufacture a simple protective circuit preventing the rupture of a module element by inserting high-speed fuses to each transistor on the positive pole side in a bridge composed of module type transistors. CONSTITUTION:In an inverter bridge consisting of IGBTs(Insulated Gate Bipolar Transistor), the positive pole side of a DC bus is connected to the collectors of the IGBTs 71-1-71-n through fuses 31-1-31-n. Bypass capacitors 8-1-8-n are further connected. Since fault currents are reduced when parallel elements are increased on complicate trouble such as the case of the short circuit of one IGBT 72-1, the emitter of the IGBT 72-1 is melted before the fuse is blown. When the emitter starts its melting, collector potential is output to a gate, another IGBT connected in parallel is turned ON and fault currents are increased, and fuses 31-1-31-n and 32 are melted, thus preventing the rupture of the IGBT.

Title: Belt type continuously variable transmission
Inventor: TAKAHASHI MASAYOSHI
IPC: F16H61/02
Filed: 1986-09-08
Abstract: PURPOSE:To improve the speed change response of a belt and extend the life of the belt by increasing the pinching force of an input shaft pulley and decreasing the pinching force of an output shaft pulley at the speed change in the accelerating direction and vice versa at the speed change in the deceleration direction. CONSTITUTION:Rotating speeds S1, S2 of input and output shaft pulleys 1, 3 are detected by detection sensors 23, 25 and fed to an arithmetic unit 27 to calculate the rotation ratio rho. The difference (e) between the speed change command value I from a speed change command detection sensor 29 and the rotation ratio rho is calculated. The voltage of proportional pressure values 17, 19 for the pulleys 1, 3 is changed based on this difference (e), and the opening is determined. At the time of acceleration, (e) is made positive, the pressing force of the hydraulic cylinder 9 of the pulley 1 is made larger than the pressing force of the hydraulic cylinder 11 of the pulley 3 an when (e) is made negative or zero, the hydraulic cylinders are controlled respectively. In either case, the pressing force is restricted to the valve that a belt is not severed. thus the high-speed response is improved at acceleration or deceleration, and the belt tension is not increased more than required.
