Title: High voltage generating circuit
Inventor: MATSUMOTO MASAHIKO
IPC: H04N3/18
Filed: 1988-12-22
Abstract: PURPOSE:To take a countermeasure for safety earlier by applying a fusing current to a protective fuse based on a detected voltage at the time of the occurrence of rare short-circuit in a high voltage coil and providing a sensitivity raising circuit to improve the detection precision of rare short. CONSTITUTION:When rare short-circuit occurs, a voltage  lBR1 corresponding to the extent of quick increase of the detected voltage increases the voltage between the gate and the cathode of a thyristor 34 to open the gate. A large fusing current flows through the route of a closed circuit formed with a coil winding part N12, the thyristor 34, and a protective fuse 32 to fuse the protective fuse 32, and the operation of a flyback transformer 20 is stopped. A sensitivity adjusting voltage i2R2 generated by the sensitivity raising circuit is applied to the gate side of the thyristor 34. Then, the resistance value of a detecting resistor 33 is increased to increase the voltage corresponding to the increase of a primary-side current lB accompanied with rare short-circuit. Consequently, the detection sensitivity of rare short circuit effectively raised.

Title: Viterbi demodulating circuit
Inventor: AIKAWA SATOSHI
IPC: G06F11/10
Filed: 1988-12-23
Abstract: PURPOSE:To decrease the probability of the change of shift register contents and to decrease energy consumption by selecting the contents of the shift register of a path memory not from a shift register on a front stage but from the other state on the same stage. CONSTITUTION:The path memory consists of a counter output 1, an ACS circuit output 2, a path memory cell 3, a selector 4 and a path memory output 5. Since the path memory cell output 5 is not connected to the path memory cell on the next stage, the stored contents are not updated or stored by sending the contents of the shift register of the path memory to the next stage, but updated and stored on the same stage, namely in the same storage circuit. Thus the probability of the change of the signal stored in the shift register is decreased, and the energy consumption can be decreased.
