Title: Pulse generating circuit
Inventor: MURATA NORIO
IPC: H03L7/097
Filed: 1984-05-07
Abstract: PURPOSE:To improve the temperature characteristic of an oscillating circuit suitable for a driving pulse generating circuit and starting oscillation always at the same phase in synchronizing with a trigger pulse by providing an oscillator, a frequency dividing circuit frequency-dividing an output pulse of the oscillator and an FF circuit. CONSTITUTION:The oscillator 50 starts oscillation at the same phase in synchronizing with the trigger pulse 16 and its oscillating frequency is controlled by a power supply voltage. A frequency dividing circuit (counter circuit) 51 frequency- divides an output pulse of the oscillator 15 into 1/m. Since a pulse generated from the frequency dividing circuit 51 is superimposed on a video signal and becomes a noise source deteriorating a screen, its operation is controlled by the FF circuit 54, causing the oscillator to be operated only at the outside of a horizontal blanking period not causing a video output. That is, the circuit 54 is set by a horizontal synchronizing pulse 16 and an operation command signal Q is given to the circuit only during the set period. The circuit counts an input pulse from the oscillator 50 accordingly and an output pulse in counting m set of pulses during the horizontal blanking period resets the circuit 54.

Filed: 1993-04-16
Abstract: PURPOSE:To provide a semiconductor light emitting element which emits light within a visible light region, does not generate strain between a substrate and a semiconductor layer and can be also used as a semiconductor laser element. CONSTITUTION:A semiconductor layer formed on an InP substrate 100 is formed of a II-VI compound semiconductor which contains Zn and Se and contains one or both of Cd and Hg. A lattice constant of the semiconductor coincides with a lattice constant of InP within a region of mixed crystal ratio wherein light inside a visible light region from red to violet is oscillated. Therefore, a semiconductor layer which enables lattice matching is acquired on the InP substrate 100. Since a semiconductor of a different mixed crystal ratio can be selected within a range of mixed crystal ratio to acquire enough large energy gap difference, a clad layer and an active layer which can be used as a semiconductor laser can be formed.

Filed: 1980-07-02
Abstract: PURPOSE:To increase the reliability of a duplex data processor of master-slave system, by using a normal clock generator of one of the data processor in common for both data processors. CONSTITUTION:In case systems A and B work as a master and a slave processor, respectively, master-slave deciding circuits 13 and 14 deliver 0 and 1 output lines 25 and 26, respectively. Accordingly, a clock switching circuit 5 supplies the clock of a clock generating circuit 15 of its own system to a logical circuit 11; and a clock switching circuit 6 supplies the clock of the circuit 15 of the other system to a logical circuit 12. Under such condtitions, if a trouble of function arises in the system A to cause the necessity of switching between the master and slave processors, the clocks are supplied to the circuits 11 and 12 of both systems from a clock generating circuit 16 of system B. In such way, the maintenance can be facilitated for the data processor since the clock generating circuit of a duplex data processor is not used in common. Thus the reliability can be enhanced.
