Title: Driving method for semiconductor device
IPC: H01L29/78
Filed: 1992-03-17
Abstract: PURPOSE:To prevent slow fluctuation of characteristics caused by deep level and realize stable operation from low speed to high speed, by applying an AC voltage in the range of a voltage lower than the operating voltage of a circuit, to a P-type semiconductor or a Schottky electrode which are formed on a substrate. CONSTITUTION:The reaction of deep level is comparatively slow. When a substrate voltage is changed, a shape shown by 3 is kept for a while. Finally, the shape has the horizontal potential distribution in a substrate which distribution is similar to the shape 2. When the potential distribution is inclided in the substrate as shown by 3, holes flow toward a substrate electrode in accordance with the potential gradient. Reaching the substrate electrode, the holes are discharged through the electrode. When the voltage is changed in the positive direction, a band has the shape shown by 4, and the holes are repelled toward the channel side. The rebelled holes are made to flow toward the substrate side by the next negative bias. Although the shape 4 is always inferior to the shape 3, retention of holes as in the case of DC bias shown by 2 is not generated.

Inventor: SATO YUMI
IPC: G01R11/02
Filed: 1993-03-18
Abstract: PURPOSE:To remove the influence of a thunderbolt and to preserve displayed data by a method where, when a thundercloud is generated, data from a metering apparatus is collected emergently by a center, the data is then returned to the measuring apparatus from the center and the displayed data is restored. CONSTITUTION:When a thundercloud radar 3 detects the passage of a thunderbolt, a center 2 collects data from a metering apparatus 1. When it is detected that the data from the metering apparatus 1 has been cleared, the center sends the collected data to the metering apparatus 1. A transmission-reception operation during this time is performed, via a transmission line 4, by a communication circuit provide witch a CPU. For example, when a metering apparatus 1 is a watthour meter, upon receiving a thunderbolt generation signal from a center 2, a CPU sends displayed data on a storage part to the center 2 via a transmission line 4. When the center 2 detects the passage of a thundercloud, it command the CPU to send present displayed data via the transmission line 4, and the CPU transmits the displayed data to the center 2. When the data is cleared at this time, the displayed data, before the passage of the thunderbolt, which has been collected by the center 2 is transmitted via the transmission line 4, and the CPU writes the data in the storage part again.

Title: Method for processing stroke order for handwritten character recognition and device for recognizing handwritten character
Inventor: MIZUNO TAKAYUKI
IPC: G06K9/46
Filed: 1997-02-27
Abstract: PROBLEM TO BE SOLVED: To easily judge the error of the stroke order of a handwritten character. SOLUTION: Supposing that a handwritten character is displayed on a first virtual screen 10, and a standard character is displayed on a second virtual screen 11, the middle point of each stroke, is virtually connected with virtual lines, and those lines are combined two each, and the sum of the internal angles of each qandrilateral generated by the virtual lines in the combination and lines virtually connecting the edge parts is calculated. Then, when the sum of the quadrilateral is sufficiently smaller than 360 deg., the error of the strode order is judged, the data of the stroke order of the two strokes at the standard character side of the virtual lines are replaced, and the error of the stroke order of the handwritten character is shifted to the standard character. Thus, the following handwritten character recognition can be attained.
Patent JP-S56156575-A (JP)
Title: Valve
Inventor: MIYAZAKI KENSUKE
IPC: F16K31/12
Filed: 1980-05-06
Abstract: PURPOSE: To minimize a pressure loss of a valve when fully opened by opening or closing a valve body through control of a fluid pressure in a pressure storage chamber as the valve body with a sector-shaped cross-section is arranged to turn between a valve chamber and a pressure storage chamber.  
     CONSTITUTION: Opening a self-return sensor head or a manual start valve reduces the pressure of fluid in the pressure storage chamber 4. This is because less fluid flows into the pressure storage chamber 4 through a hole 12 than that released into the air through the sensor head and the manual start valve. Therefore, a valve body 11 with a sector-shaped cross-section is caused to turn with a rotary moment produced counter-clockwise due to a pressure fluid in a valve chamber 3 leading the valve to open, so that the fluid on the primary side flows out to the secondary side. This eliminates bent passage preventing any large pressure loss of a valve when opened fully.

Title: Bias voltage applying device for avalanche photodiode
Inventor: HIGUCHI HIROSHI
IPC: H01L31/107
Filed: 1982-04-09
Abstract: PURPOSE:To improve the performance as well as to minimize the size of the titled device, by using exclusively a light emitting diode and a high-level resistance to secure nearly a fixed high level of sensitivity for an avalanche photodiode. CONSTITUTION:The nter-terminal voltage VC of a high voltage bias power supply 9 is higher than the breakdown voltage, and the bias light is illuminated to a photodetecting surface 3 of an avalanche photodiode APD2. Therefore an optical current flows to a high-level resistance 7 and a resistance 8 when the APD2 tends to cause breakdown. Thus the voltage is dropped, and the bias voltage of the APD2 is set at the level obtained immediately before the breakdown. The sensitivity of the APD2 can be set at a fixed level regardless of the temperature change by selecting a proper level of the serial resistance value of resistances 7 and 8. As a result, it is possible to use stably the APD2 at a high level obtained immediately before the breakdown.

Abstract: PURPOSE: To simplify a process for producing a liquid crystal panel by selectively removing the oriented films of the external electric circuit connecting parts of the liquid crystal panel sealed with a liquid crystal compsn. between the substrates by a plasma ashing treatment under the atm. pressure. CONSTITUTION: A gaseous mixture 15 composed of He and O2 is introduced into a blow-off type line gun 13 and thereafter an RF power source 14 is turned on to generate plasma 16. At this time, the liquid crystal panel 18 coated with the oriented film over the entire surface is installed on an electrically grounded stage 17 right under the line gun 13 in such a manner that the plasma falls onto the terminal part 19 of the panel. The spacing between the front end of the line gun 13 and the terminal part 19 of the liquid crystal panel is so set as to be kept constant at about 5mm. An abnormal discharge arises if the terminal edge and the front end of the line gun 13 approach and, therefore, the terminal part 19 is so installed that the generation center of the plasma 16 comes to the flat part of the terminal part.  The terminal part 19 of the liquid crystal panel 18 treated under prescribed conditions is so formed that the oriented film is invisible as far as the part is visually observed.
