IPC: G01M11/06
Filed: 1988-09-09
Abstract: PURPOSE:To decide the contour of characteristic at high speed by incorporating a light distribution pattern as a digital image and performing the processing of the digital image. CONSTITUTION:A video signal obtained by the image pickup by means of a television camera 2 is digitized by an A/D converter 3 and also the peak value thereof is extracted by a peak value detection circuit 5. At the same time, the digital value is changed in terms of level by a level converting device 4 and stored in an image memory 7. Next, the result of the circuit 5 is read at the time of completing the fetching of the image. The diaphragm of an EE lens 1 is adjusted through a D/A converter 6 according to the peak value so as to refetch the image signal at an appropriate level. Then, an area scanning circuit 8 scans a corresponding area in the image which is fetched at the appropriate level and differentiation processing 11 is performed to the image simultaneously with the integration by an integration circuit 10. The output from the circuit 11 is binarized 12 and binary image data in a widow is taken out 13 to be stored 14. Thereafter, an optical axis and the contour of characteristic can be extracted by the CPU 15.

IPC: H01L21/74
Filed: 1985-10-07
Abstract: PURPOSE:To form a buried diffusion layer having uniform concentration and film thickness to a semiconductor device by directly patterning a diffusion layer shaped onto the whole surface of a substrate and forming a diffusion source. CONSTITUTION:An applying film 12 is shaped onto the whole surface of the surface of an silicon substrate 21, and a diffusion layer 13 is formed through heat treatment.

Abstract: PURPOSE:To miniaturize a temperature controller and also to omit the wiring of detecting lead wires by detecting the variation of the resistance value when a heating element is energized and stopping the heating when the coincidence is obtained between said resistance value and the resistance value of the heating element. CONSTITUTION:A resistance detecting circuit 5 of a resistance detector 6 receives the signals from a voltage detector 3 and a current detector 4 and converts them into the resistance value of a heating element 2 to detect it as the resistance value. Then a comparison arithmetic circuit 10 receives the set resistance value and the detected resistance value from a resistance setting circuit 8 and the circuit 5 respectively and compares them with each other. When the coincidence is obtained between both resistance values, the circuit 10 delivers a power supply opening signal to a relay actuating circuit 11 of a heater power supply switching device 12. Thus the circuit 11 opens a relay Ry and therefore the element 2 stops its heating. In other words, the element 2 stops its heating when the heating temperature reaches a set level.
