Title: Igntion timing control unit for internal combustion engine
Inventor: KOMURASAKI SATORU
IPC: F02P5/152
Filed: 1980-12-08
Abstract: PURPOSE:To obtain MBT within the range of non-knocking by detecting the failure of a knocking sensor based on its output and by preventing an excessive advance of ignition timing of engine. CONSTITUTION:Based on an electric current signal (a) to an ignition coil, an electric current (b) flows to the ignition coil. When a knocking sensor normally operates, a constant output is generated as indicated by a signal e1. When the knocking sensor failures, the output is turned into a noise signal generated only when the current is applied or when an ignition spark is generated as shown by a signal e2. When the signal e2 generated during failure is masked by pulses of ignition timing (signal d), no signal is output as indicated by a signal f2, thereby detecting the failure of the knocking sensor. With this construction, the failure of knocking sensor can be accurately detected.

IPC: G01R19/00
Filed: 1981-10-29
Abstract: PURPOSE:To detect charging voltage of a main capacitor by converting it to digital information without using a regular A-D converting circuit, by detecting said charging voltage by use of an oscillating circuit containing a neon tube which flickers on frequency corresponding to said voltage.

Title: Charge couplind device cell
Inventor: KEI UIIN KARUBIN YANGU
IPC: G11C19/28
Filed: 1989-07-05
Abstract: PURPOSE: To improve the charge transfer efficiency and operating speed of each cell of a CCD, by forming a potential gradient in one direction in which charges are transferred in the channel area of each cell. CONSTITUTION: The channel potentials at regions below the electrodes 91-93 of cells 1-3 are inclined in charge transferring direction. Since forces act on charge carriers in channel regions below the electrodes 91-93 in the transfer directions due to electric fields generated by the potential gradients, the drift speeds of charges increase. The drift speed increases of the charge carriers become particularly conspicuous at or near the terminating point of time of a clock cycle at which the differences between the charge carrier densities of adjacent cells become smaller and the potential gradients become gentle due to a clock.  Therefore, small amounts of charge carriers remaining in the cells and be pushed completely to an accepting cell side at or near the terminating point of time of the clock cycle at which the driving forces of the charge carriers are reduced by the electric fields added by the inclined channel potentials. Therefore, the charge transfer efficiencies of the cells can be improved substantially even when the frequency of a clock signal becomes higher.
