IPC: H01L29/78
Filed: 1990-10-26
Abstract: PURPOSE:To prevent insulation breakdown and realize high breakdown voltage by putting second conductivity type impurity diffused region positioned most outside in a shape such that it has a shallow part on the periphery side of a substrate. CONSTITUTION:Out of a plurality of the second conductivity type impurity diffused regions 3, which are formed at the surface parts of first conductivity type semiconductor regions 3 on the surface side of a semiconductor substrate 2, the region 3' positioned most outside has a deep part 31 at the center, and has a shallow part 32 without a channel formation area CH on the periphery side of the substrate 2, and they are in circular shape, surrounding the second conductivity type impurity diffused region 3 inside in all. Accordingly, when a depletion layer is formed, there is no remarkable curve at a place h in the vicinity of the terminal of the depletion layer H, and it is a gentle curve, and the condition of electric field concentration is relaxed. Hereby, insulation breakdown is prevented, and high breakdown voltage can be realized.

Filed: 1993-10-25
Abstract: PURPOSE:To measure the outer shape of a shape steel accurately and rapidly by driving a two-axis stage mechanism and then moving a detection head with a laser displacement meter along the shape steel. CONSTITUTION:An H-shape steel 11 is carried to a measurement position by a roller conveyor 22 and gauge is measured by detection heads 17 and 18 laid out at the measurement position of the reference gauge. After the width A and length B are calibrated, the heads 17 and 18 are moved, the rough dimensions of a measurement target are measured and are compared with already input data for determining the type of the shape steel, and then surface XY coordinates are measured precisely with the heads 17 and 18 having a specific clearance to the steel 11. In this case, the height to the steel 11 is measured by a laser displacement meter for measuring a vertical position and the distance to the side surface of the steel 11 is measured by the laser displacement meter for measuring horizontal direction. A flange width W and a web length L of the steel 11 can be measured from the measured X and Y values. When measuring the inner and outer sides of the flange, the heads 17 and 18 are rotated by 180 degrees and the dimension of the steel 11 is calculated from the length in XY directions.

Title: Judgement of mold releasability of synthetic resin molding material
Inventor: NARUSE SHIGERU
IPC: B29C45/40
Filed: 1986-12-09
Abstract: PURPOSE:To enable the measurement of mold releasability of a synthetic resin molding material quantitatively and simply, by a method wherein a material is cast into a cavity, a molded product is ejected by a pressure detector by making use of a measuring hole and mold release force is measured. CONSTITUTION:A cavity block 1 is taken out of a mold directly after molding and a support pin 2 is pulled out immediately. Mold release force of a molded product is measured by ejecting the same by a pressure detector 4, for example, a push-pull gauge through a measuring hole 5 while a mold temperature is being held on. As a submarine gate is broken, resistance owing to gate break does not exist and only mold release force of the molded product can be measured. A draft of a cavity is set up like 0 deg., 0.5 deg., 1 deg., 2 deg. so as to judge mold release force at favorable accuracy and the title method is so designed that the existence of plating on the surface can be compared.

Filed: 1985-12-24
Abstract: PURPOSE:To make the picture quality deterioration unremarkable by comparing the frequency of occurrence of a long code word with a line address and converting the word into a short code word tentatively when the frequency of occurrence of the long code word is high. CONSTITUTION:After the output of a counter 6 counting a long code word generating pulse (f) is weighted and compared with a line address signal (i) from a quantization circuit 3 by a comparator and sent to the quantization circuit 3 as a quantization characteristic switching signal (h). When the long code word occurrence frequency (g) is larger relatively in comparison with the line address (i), only the short code word is switched tentatively for a coarse quantizing characteristic so as to decrease the frequency of the occurrence of the long code word and then the characteristic is restored to the normal quantizing characteristic. The deterioration in the picture quality is made unremarkable by distributing the generating point of the coarse quantization characteristic of the short code word only to discrete points on the line in this way.
