Title: Data output circuit
Inventor: OSHIMA SHIGEO
IPC: H03K19/003
Filed: 1987-03-23
Abstract: PURPOSE:To prevent the occurrence of malfunction by turning on plural MOS transistors (TRs) inserted between a data output terminal between the source and drain and a power voltage corresponding to a low level in parallel sequentially in a different conduction start time in outputting a low level data from the data output terminal. CONSTITUTION:An output signal N3 of a delay circuit 35 rises to a level '1' in a prescribed time delay after a signal N1 rises to a level '1'. Since the voltage of the signal N3 is sufficiently higher than the threshold voltage of an N-channel MOS TR, a TR 12B is conductive thereafter and a discharge path for the load capacitance connected via a terminal T1 is formed further. Since the increment of the discharge current by the TR 12B is very slight in this case, overshoot noise generated to ground and power voltage side due to parasitic resistive and inductive component existing in the current path is suppressed remarkably. Thus, malfunction of the internal circuit due to fluctuation of the power potential is prevented.

Title: Reflection type photoelectric switching device
Inventor: TSUMURA TOSHIHIRO
IPC: H03K17/78
Filed: 1987-03-23
Abstract: PURPOSE:To surely detect an object to be detected by providing a modulator to a reflecting section and supplying the light being the result of modulating the incident light from a projecting part to a photodetection part when no object to be detected exists. CONSTITUTION:The reflecting section 13 consists of a normal reflecting plate 16 and a crystal plate 17 arranged to the front face of the reflecting plate 16 and acting like an optical modulator. When no object to be detected exists in either of the incident optical path and the reflected optical path, the reflected light in a form that the incident light (a) is interrupted at a period T of transparent-opaque property of the crystal plate 17 enters the photodetection section 15 and the photodetection section 15 generates an electric signal corresponding to the reflected light (c). On the other hand, if an object to be detected such as a human body enters the incident optical path or the reflected optical path and the reflected light reaching the photodetection section 15 is shielded, a signal smoothing section 23 generates a low level output signal. Thus, the passing of the object to be detected can be detected.

IPC: H04N9/81
Filed: 1984-04-05
Abstract: PURPOSE:To eliminate a delay of a chrominance signal and a black and white video signal and to obtain satisfactory reproduced picture information by providing a delay circuit for delaying the reproduced black/white video signal by one horizontal scanning period. CONSTITUTION:The 3rd delay circuit having one-hour delay time is inserted between the 1st FM demodulator 12 and an adder 22. An output signal (e) of the demodulator 12 is delayed by one hour by means of a delay circuit 23, which outputs a signal (l). Assuming that a color difference signals Rn and (Bn-1+ Bn+1)/2 are outputted to respective terminals of a switch circuit 18, a synthesized carrier chrominance signal is added to a Y signal component outputted from the circuit 23 by means of the adder 22 and a composite video signal is outputted, said Y signal component is Yn, which is the same as the relation between an output Y signal and an output color difference signal of a matrix circuit at the time of recording. Thus the composite video signal never has the time delay of the chrominance signal and the video signal.
