Title: Solid-state image pickup device
Inventor: KURASHIGE TOMOYUKI
IPC: H04N5/335
Filed: 1987-10-19
Abstract: PURPOSE:To erase the generation of a shading and to reproduce a smooth image by providing a means to cancel fluctuation in a vertical scanning period to be generated in a bias potential edge, and obtaining a preamplifier output signal whose black level is uniform. CONSTITUTION:At a normal time, level difference is generated between a vertical returning period and a scanning period and further, since the operating reference potential of a preamplifier in such a low frequency area is not smooth, the shading is generated at a scanning starting time so as to be shown in a Vo waveform. Now, when a VIN is added into a JFET source edge through a resistance R, a sag to be generated to the source edge in advance is canceled and changed like a Vs' in the figure. The size of the change and a time constant are determined by the adding resistance R and a source edge impedance in the low frequency area. Thus, by consciously supplying the sag to the source edge, potential difference Vgs between a gate edge and the source edge can be kept almost constant in the scanning period. Thus, the output waveform is changed like a Vo' and the shading to be a problem can be suppressed.

Title: Measuring apparatus for battery capacity for electric vehicle
Inventor: SAKAI KENICHI
IPC: G01R31/36
Filed: 1998-09-17
Abstract: PROBLEM TO BE SOLVED: To make an indication accuracy at the last stage of discharge higher by making the difference between a power capacity value and an accumulated capacity value at discharge completion as the initial value at next-time calculation of the accumulated capacity value. SOLUTION: If a further difference X2 is generated between a power capacity value and an accumulated capacity value at discharge completion, the initial value at the beginning for computing the next third accumulated capacity value is set to X1+X2. Then if this processing is repeated, and when the difference between the power capacity value and the accumulated capacity value at n-th discharge completion is Xn, the initial value of the (n+1)-th accumulated capacity value is set to ΣXj (j=1 to n, a natural number). Consequently, errors which can accumulated capacity value and a power capacity value contained in the battery contain respectively are concentrated at the initial stage of full charging, and accuracy of capacity indication at the last stage of discharging becomes precise and uniform.  As a result of this, the traveled distance for each one segment in indication of a battery capacity by an indicator becomes equal, when discharge approaches its last stage, and unexpected running out of the battery due to recognition error by the new member 1 is prevented.

Abstract: PURPOSE:To improve a high-frequency characteristic and a forward characteristic by providing a deep groove on one conductivity type conductor substrate, an opposite conductivity type semiconductor region formed in this groove and a Schottky barrier electrode formed on the semiconductor region and the semiconductor substrate. CONSTITUTION:A deep guard ring groove 3 is selectively formed on an n-type epitaxial growth layer 2 on an n-type semiconductor substrate 1, and inside this guard ring 3, impurities are selectively diffused to form a p-type guard ring region 4. Next, a Schottky barrier electrode 6 is formed on an epitaxial growth layer 2 surrounded by the guard ring region 4 and the guard ring grove 3.
