Title: Solid image pickup device
Inventor: OOTA YOSHIO
IPC: H04N5/335
Filed: 1977-12-15
Abstract: PURPOSE: To remove background noises and obtain a fine picture with no clock noises and a high signal to noise ratio by using two-dimensional light information.  
     CONSTITUTION: Output signal (a) of image pickup element 31 is gated by a pulse which synchronizes to one of the first horizontal signals of 1 field effective scanning signals b in gate circuit 33, so that it becomes signal c; then, signal c is changed to signal d through delay line 34 with a 1H interval. Signal d is supplied to gate circuit 38 through level adjusting circuit 37 and gated by pulse e applied from pulse generator 32 so that the supply is cut off only vertical blanking interval B; then, it is recycled by the loop consisting of circuits 34, 37 and 38, so that a signal component from the light-screening diode array of element 31 is entered to differential amplifier 35 of the vertical effective scanning interval. On the other hand, 1H signal to which light-screening from element 31 is not applied superposes clock noise component and background noise component on its picture signal and is entered to amplifier 35. As the result, output video signals without unnecessary components can be obtained.

Title: Abnormality detector for capacitor in inverter
Inventor: KOGURE SHINJI
IPC: H02M7/48
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To reduce a capacity required for a smoothing capacitor, on the DC side of an inverter which is employed in electric automobile or the like. SOLUTION: Voltage variations across a smoothing capacitor 10 caused by deterioration thereof is detected, based on the voltage measurement of a voltage sensor 12. Voltage variation accompanying deterioration has a period corresponding to the PWM carrier frequency, and a voltage variation monitoring section 30 is provided with a band-pass filter 32, in order to extract a voltage variation component having that frequency. When an extracted voltage variation exceeds a specified abnormality decision reference level, a decision is made that the smoothing capacitor 10 is abnormal, and a vehicle is stopped. Deterioration can be detected before a vehicle is damaged by comparing a deterioration decision reference level which is set lower than the abnormality decision reference level with the voltage variation.

Abstract: PURPOSE:To simplify a production process by using aluminum as a base material for a master disk and cutting and forming fine ruggedness for reproduction of tracking guides by precision lathing onto a front face of the aluminum base material. CONSTITUTION:The fine ruggedness for reproduction of the tracking guides is cut and formed by precision lathing on the aluminum base material 1. More specifically, a diamond cutting tool 4a for forming recesses having the tips of the width equal to the width of the recesses 2 for reproduction of the intended tracking guides and the diamond cutting tool 4b for working the projecting parts to a specular surface having the tips of the width equal to the width of the projecting parts 3 for reproduction of the tracking guides are juxtaposed in tight contact with each other in the transverse direction. The tip end of the tool 4a is projected from the tip end of the tool 4b by as much as the depth of the recesses and the aluminum base material mounted to the rotating spindle of a lathe is rotated. The two tools 4a, 4b are brought into contact with the surface of the base material 1 and while the tools are fed in the radial direction, the base material is cut. The production process is thereby simplified.

Title: Semiconductor device
Inventor: MITARAI GOROU
IPC: H01L29/808
Filed: 1980-10-29
Abstract: PURPOSE:To reduce a dicing area by forming monitoring parts beneath wire bonding pads of a source and a drain of the main body of a junction type FET, thereby eliminating the area for the monitoring parts. CONSTITUTION:The monitoring parts 2 are formed beneath the source wire bonding pad 9 and the drain wire bonding pad 10 of the main body 1 of the junction type FET via an SiO2 film 8. In the manufacture of the junction type FET, the monitoring parts 2 are required for controlling the characteristics of the main body, but not required after the completion of the characteristic control. Since the pads 9 and 10 are formed at the final manufacturing process of the FET, they are not yet formed when the monitoring parts 2 are used for the characteristic control of the FET. Therefore the FET can be formed without any obstacles. In this method, the dimension of the dicing can be reduced by the area of the monitoring parts 2. Since the capacity is largely reduced, the high frequency characteristics can be improved.
