Title: Detecting apparatus of surface defect
Inventor: FUJIKAKE YOUICHI
IPC: G01N21/892
Filed: 1989-05-15
Abstract: PURPOSE:To eliminate the effect of a processing applied to a material to be inspected and thereby to detect a surface defect with high precision by generating a smoothed image signal from an original image signal picked up by a TV camera and further by generating a differential image signal from the original image signal and the smoothed image signal. CONSTITUTION:An original image signal picked up by a TV camera 61 is made to branch into an image processing unit 3 and a monitor TV 8 by a switching unit 7. The unit 3 has a variety of arithmetic circuits and it smoothes the original image signal to generate a smoothed image signal and further determines a differential between the two signals to generate a differential image signal. Composite data of waveforms corresponding to nonuniformity in temperature and a flaw are obtained from the original image signal, while data corresponding to the nonuniformity in temperature are obtained from the smoothed image signal, and further data corresponding only to the flaw varying at a high frequency are obtained from the differential image signal. By binary-coding a differential image, accordingly, data specifying the position of the flaw are obtained. According to this constitution, a surface defect can be detected highly precisely without being affected by a processing applied to a material to be inspected.

Title: Formation of toner image
Inventor: MATSUO MAKOTO
IPC: G03G15/05
Filed: 1988-05-17
Abstract: PURPOSE:To enable long-time storage of high quality and high resolution and to form a toner image of picture quality at a point of time corresponding to a purpose by recording an image electrostatically and forming the toner image at the optional point of time. CONSTITUTION:A charge holding medium 3 is set at an interval with a photosensitive body 1 and a voltage from a power source 17 is applied between electrodes 7 and 13. When light is made incident from the side of the photosensitive body 1, a photosensitive layer 9 at the light incident part becomes conductive to cause discharge with an insulating layer 11, where charges are accumulated; and the voltage is turned off at the end of the exposure and the charge holding medium 3 is taken out, thus finishing the formation of the electrostatic latent image. Then the photosensitive body 1 and charge holding medium 3 are separated from each other and then the insulating layer 11 is separated while holding the charges. When surface analog recording is performed by this recording method, the high resolution is obtained and the record is maintained for a long time without discharging without reference to its light-dark storage environment. Consequently, the long-time storage is enabled, toner development is performed at any time to visualize the image, and the quality and resolution of the image are high.

Title: Selective oxidation method of semiconductor substrate
Inventor: SHIBATA SUNAO
IPC: H01L29/78
Filed: 1977-10-11
Abstract: PURPOSE: To prevent impurity exudation to element regions from field regions and produce an IC of superior dynamic characteristics by superposing an ion implanting mask of an outside dimension larger than that of a field oxidizing mask on the field oxidizing mask.  
     CONSTITUTION: SiO 2  12, Si 3 N 4  13, SiO 2  thick film 14 are laminated on a P type Si substrate 11. Resist 15 is provided slightly wider than element forming regions. When the substrate is treated with HF after treatment for about 10 minutes in CF 4  plasma, the film 14 under the resist is etched away, leaving the film 14 of an inverted taper. The taper may be controlled as desired depending upon treatment conditions. The film 13 is etched away through the mask 14 and B ions are implanted to create a p +  layer 16. If an oxide thick film 17 is created through high temperature oxidation through the mask 13, B does not exudate in the element region because the ion implantation mask 14 is wider than the selective oxidation mask 13. Next, the films 13, 12 are selectively opened with holes, where gate film 18 and poly Si 19 are provided, and n +  type source, drain 20, 21 are made. This constitution obviates the decrease in operating speed and enables desired channel widths to be obtained

Abstract: PURPOSE:To improve the operability of a supervisory device without deteriorating the response speed by using a means which detects the abnormality occurrence probability and carrying out with preference a processing program to realize an original function in case of the high abnormality occurrence probability. CONSTITUTION:A ROM 2 stores a processing program which can carry out an original function that monitors the physical value and produces an alarm when detecting the abnormality and an additional function independently of each other.

This waiting time is set at a RAM 3 and an alarm generating probability detector 4 changes properly said waiting time when the abnormality occurrence probability is high. As a result, the processing program which can realize the original function is carried out with preference and therefore the operability of a supervisory device is improved without deteriorating the response speed.
