Title: Formation of isolation oxide film
Inventor: TAKAHASHI HIROSHI
IPC: H01L21/76
Filed: 1994-04-12
Abstract: PURPOSE:To suppress the occurrence of junction leak currents at the end of an isolation oxide film having a prescribed thickness and the elongation of a depletion layer below an element separating area by forming the isolation oxide film by separately performing oxidizing processes in a plurality of stages and forming a channel stop layer by implanting impurity ions between each process. CONSTITUTION:In step l, a polysilicon film and Si3N4 film are successively formed on an SiO2 film after forming the SiO2 film on a substrate and, in step 5, the polysilicon film is exposed by etching the SiO2 and Si3N4 films. In step 6, a first oxidizing process is performed for forming a LOCOS oxide filnt (isolation oxide film) by oxidizing the exposed polysilicon film. In step 7, a channel stop layer is formed by implanting boron ions into an element separating area in which the isolation oxide film is formed and, in step 8, a second oxidizing process is performed. Namely, the isolation oxide film is formed to a prescribed thickness by separately performing oxidizing processes in a plurality of stages. Therefore, a leakage current can be made smaller by relieving a junction electric field at the end of the isolation oxide film.

Filed: 1987-04-23
Abstract: PURPOSE:To exactly assign a desired region by assigning the prescribed region of read copying information by manual writing input, detecting the beginning point and end point of the manually written input information, correcting the connection thereof, specifying the assigned region and processing the copying information in accordance with the specified input region. CONSTITUTION:The copying information is read from a copying original and the prescribed region of the read copying information is assigned by a manual writing input means 180. The beginning point and end point of the manually written input information from the means 180 are then detected and the connection of the beginning point and end point is corrected by the result of the detection. The assigned region is specified in accordance with the corrected input information and the copying information is processed. The correction is executed by averaging the information on the position of the beginning and the information on the position of the end point by which the position of the beginning point and the position of the end point are made to coincide with each other. Since the input graphics are thereby automatically corrected, the desired region is exactly assigned.

Title: Electrophotographic sensitive body
Inventor: OKUGAWA YASUNARI
IPC: G03G5/14
Filed: 1983-06-03
Abstract: PURPOSE:To obtain a photosensitive body for electrophotography with which a copy having no deterioration in image quality such as a photographic fog is made with a photosensitive body for electrophotography which has a protective layer dispersed with pulverous metallic oxide powder in a binder resin as a surface layer by specifying the grain size distribution of the pulverous metallic oxide powder in the protective layer. CONSTITUTION:The ratio of the pulverous metallic oxide powder in a protective layer is 20- 70wt% in the layer upper within 1mum than the surface and 10-60 wt% in the layer lower than the same and the ratio of the pulverous metallic oxide powder in the upper layer is made larger than in the lower layer. The concn. in the upper layer is thus made larger than the concn. in the lower layer and therefore the protective layer has excellent wear resistance on the surface. On the other hand, the ratio at which a binder resin occupies in the photosensitive layer, that is, the photoconductive layer or the lower layer adjacent to the other layer such as the intermediate layer or the like is relatively large and therefore the photosensitive layer has good adhesion. The thickness of the upper layer where the concn. of the pulverous metallic oxide powder is large is relatively small as compared to the overall thickness of the protective layer and consequently the protective layer is excellent in terms of transparency as well and has high resolving power. The decrease in photosensitivity is controlled as compared with the photosensitive layer having no protective layer. A satisfactory result is obtainable with the residual potential and the photographic fog by decreasing the difference between the concn. in the upper layer and the concn. in the lower layer.

Abstract: PURPOSE:To improve the rise-up of a stepping motor by high-speed driving and to improve the converging property to a specified target stopping position. CONSTITUTION:Main starting pulses, which are supplied into coils L1 and L2, determine the rotating direction of a rotor 6 based on the polarity of the pulses.

Thus, the inertial rotation is suppressed. When the effect of the supply of the reverse-phase pulses is generated, correcting pulses having the same polarity as the main starting pulses are supplied, and the shortage in rotation of the rotor 6 caused by the reverse-phase pulses is corrected. Then, stop-position specifying pulses comprising a plurality of pulses are supplied, and the stabilized stop-position state of the rotor 6, which is determined by the duty ratio of the stop-position specifying pulses, is maintained.
