Title: Discharge lamp lighting device and image display device using it
Inventor: TAKAYA MANABU
IPC: H05B41/18
Filed: 1997-02-21
Abstract: PROBLEM TO BE SOLVED: To prevent the transfer of arc discharge due to pulse leak for more safety by forming the same potential of a conductive case, in which an ignitor is stored, as the potential of an input line for a pulse transformer. SOLUTION: An ignitor 30 inputs a DC current from a chopper circuit 2 and generates and outputs high voltage pulse to light a high pressure discharge lamp 6. The high pressure discharge lamp 6 is lit with high voltage pulse supplied via a connector 50. A conductive case, in which the ignitor 30 is stored, is formed of conductive material to be partly connected to a high voltage applied line power supply side, where high voltage is output from a high voltage generating circuit. In this way, if extremely high voltage pulse from the ignitor 30 leaks, the transfer of arc discharge is prevented only by glow discharge near a pulse transformer for more safety.

Abstract: PURPOSE:To obtain a broad lock range by making a phase comparison between a control oscillator and horizontal synchronizing signal, by feeding the output back to the control oscillator and then by feeding the output of a phase comparison between the horizontal synchronizing signal and 1H-delayed signal back to the control oscillator. CONSTITUTION:A signal obtained by stepping down 39 the output of control oscillator 38 by one half is phase-compared 40 with horizontal synchronizing signal 18 and its output is fed back to oscillator 38 via error mixer 41 to obtain the output signal of oscillator 38 of a frequency twice a horizontal synchronizing frequency locked to signal 18. On the other hand, signal 18, after being delayed by 1H at 1H line delay circuit 47, is phase-compared with signal 18 to detect the frequency variation of signal 18. The outputs of circuits 48 and 40 are error-mixed 41 to widen the lock range against the variation in the period of signal 18. When this circuit is composed of nearly the same one-shot multivibrator as oscillator 38 and circuit 47, the lock range against the variation of wide input horizontal synchronism can stably be obtained including temperature characteristics.

Title: Detecting circuit of fault of sequential circuit
Inventor: OKAMORI TOSHIYUKI
IPC: G06F11/22
Filed: 1983-03-11
Abstract: PURPOSE:To realize a compact, speedy circuit which detects a fault of a sequential circuit without fail by using one OR gate and one set and reset type FF instead of one set of a sequential circuit of duplicated system. CONSTITUTION:The set and reset type FF39 is set to 1 when an input signal 31 is 1 and a clock signal 32 is 1, and reset to 0 when the FF37 of a final stage outputs 1 and the clock signal 32 is 1. The outputs of the FF39 and an OR circuit 38 normally coincide with each other, so both are connected to an exclusive OR circuit 40 to make a comparison. The comparison result is received by an FF41. When the output of the exclusive OR circuit 40 is 1 and a clock signal 33 is 1, the FF41 is set to 1. This outputs a fault display signal 42. If one of FFs 34-37 still outputs 1 without being reset, the FF39 is reset, but the output of the OR circuit 38 is still 1, so a dissidence is caused, thereby outputting the fault display signal 42.
