Title: Production of semiconductor device
Inventor: NOZAWA HIROSHI
IPC: H01L21/28
Filed: 1977-10-13
Abstract: PURPOSE: To prevent shorting of wiring to source and drain and gate electrodes without particularly taking margins for mask alignment.  
     CONSTITUTION: After a field oxide film 2 is selectively formed on a p type Si substrate 1, poly-Si 4 is superposed on an oxide thin film 3, and the layer 4 is etched through the double layer masks of nitride film 5, resist 6. At this time, the layer 4 is side etched. The resist 6 is removed, and the film 3 is etched with openings through the mask 5. At the time of providing n type drain, source 7, 8 and a  protecting film 9, part thereof enters under the eaves of the film 5. A resist mask  10 is made. At this time, even if the mask is deviated, opening windows in the layer 8 causes the film 5 to act as an etching-resistant film, enabling connection holes to be surely formed irrespective of the deviations. Next, the resist 11 is removed and Al wirings 11 are made. Even if the connection holes and gate electrode overlap on the mask, the nitride film 5 becomes an etching stopper, preventing shorting of the Al wirings and gate electrode. Since there is no need for any margin of the mask in this way, the scale of integration improves

Title: Dividing method for gradation screen of digital video signal
Inventor: HIRAI MITSUKAZU
IPC: H01L33/00
Filed: 1989-05-16
Abstract: PURPOSE:To execute the display having a gradation at every picture element by forming one frame by plural pieces with respect to one screen of a monochromatic digital video signal for a light emission diode matrix display screen, and executing a frame feed. CONSTITUTION:Gradation video signals 7a-7c are inputted by a video synchronizing signal 7', and displayed as a gradation rough screen A 10 - a gradation rough screen C 12 by screen synchronizing signals 9a - 9c, respectively. By synthesizing these rough screens, a gradation main screen is constituted, and it is considered to be one frame of an image. In the case a line display time 8a exclusing each blanking time is the same, when one gradation main screen 13 is constituted of three pieces of gradation rough screens, each display time of picture elements of 14 - 16 in the main screen display time becomes 3X8a, 2X8a, and 1X8a. As far as it is concerned, in the case a switching period of the gradation main screen is an extent that flickering is not felt, a ratio of brightness of its picture elements is felt as 3:2:1. A picture element 17 is a background of non-display. In such a way, the display having a gradation can be executed at every picture element.

IPC: G01N27/38
Filed: 1984-06-14
Abstract: PURPOSE:To prevent the secular degrading in the sensitivity of an immobilized enzyme electrode, by applying a high voltage depending on a voltage applied to a sample electrode to a meshy electrode provided in front of the sample electrode as immobilized enzyme electrode to adsorb blood corpuscles or the like on the meshy electrode. CONSTITUTION:A higher voltage is applied to a meshy electrode 11 provided in front of an immobilized enzyme electrode 2 than the reference voltage of a power source 6 to be applied to the electrode 2 and an opposed electrode 3 thereof from a power source 23. Therefore, the electrode 11 adsorbs blood corpuscles, blood platelet, various proteins or the like as factors for causing the lowering of the sensitivity of the electrode 2 by electrophoresis. Thus, the attaching of blood corpuscles or the like to the electrode 2 is eliminated thereby preventing the secular degrading in the sensitivity of the electrode 2.
