IPC: G06K15/12
Filed: 1986-10-31
Abstract: PURPOSE:To prevent a skew, a V-oscillation and a color fading at the time of switching an input picture and a reproduced picture by synchronizing the switching timing of a signal switching circuit with a synchronizing signal from a synchronizing control part when a memory writing command is inputted. CONSTITUTION:When a memory writing command signal B is inputted to a system control part 12, a memory writing command signal C is outputted to a memory control part 10 and an output switching signal D is outputted to the signal switching circuit 9. When a prescribed period is delayed from the leading of the signal C, the memory control part 10 leads the output switching signal D. Namely, the output switching signal S is synchronized by the synchronizing control part 11 and a leading timing is set immediately after or after the trailing of a memory writing control signal E by a counter or the like. Thereby, at the time of switching an input video signal and a reproduced video signal occurring on a monitor screen after the memory wiring command is inputted, phenomena such as the color fading, the skew, the V oscillation is not produced but the picture quality of the monitor screen is improved.

Title: Overcurrent detecting/protective unit for inverter
Inventor: SETO MAKOTO
IPC: H02H7/122
Filed: 1989-10-03
Abstract: PURPOSE:To enable judgement at which side overcurrent occurred by disabling an AC side overcurrent detector upon detection of overcurrent at DC side while disabling a DC side overcurrent detector upon detection of overcurrent at AC side. CONSTITUTION:Current value at DC side is fed to a comparator 4 while current value at AC side is fed to a comparator 7, and when they exceeds a predetermined level outputs from the comparators 4, 7 go to H level. AND gates 15, 18 and FF 5, 8 constitute a circuit for receiving only such signal as going H level at first. In other words, if the output from the comparator 4 goes H level at first with FF 5, 8 being reset, FF 5 is set through the AND gate 15. Since the AND gate 18 is closed by the output from the FF 5 even if the output from the comparator 7 goes H level subsequently, the FF 8 is not set. By such arrangement, we can judge at which side overcurrent occurred through displays 6, 9.

Abstract: PURPOSE:To accurately detect only the intensity of an impact by holding the level of a high-frequency component contained in an acceleration sensor output when the acceleration sensor output exceeds a 1st level and the high frequency component of the sensor output exceeds a 2nd level. CONSTITUTION:The voltage signal Va of an acceleration sensor 1 is passed through an HPF17 to extract its high-frequency component, which is amplified 15 to become a voltage Ve; and the voltage is inputted to the positive terminal of a comparator 19, and also integrated by a LPF23 and inputted to the negative terminal. A diode 21, however, is connected to the negative terminal, so a reference voltage Vr1 is inputted to the negative terminal of the comparator 19 for a signal lower than the reference voltage Vr1 and the output signal is inputted for a signal higher than the voltage Vr1. The comparator 19 outputs an H-level pulse signal Vg within a range of Ve>Vf to open a switch 26, and the peak value of the signal Ve is held in a capacitor 27. This held voltage is converted by an A/D converter 28 into a digital signal Dd, which is read in a CPU29 to detect sound height data DP corresponding to the intensity of the impact.
