Title: Pattern coating method
Inventor: MIYAZAKI MASANOBU
IPC: B05D5/06
Filed: 1980-04-29
Abstract: PURPOSE: To perform pattern coating easily and readily by drying partially a coating surface, applied with an emulsion coating material, by spot-heating and then by further applying an emulsion coating material on said surface.  
     CONSTITUTION: An emulsion coating material (ground coating material), applied on a substrate surface, is partially dried gy spot-heating and on it, another emulsion coating material differing in color from the 1st emulsion coating material is applied. Then, the undried part of the ground coating material mixes with the emulsion coating material applied on it naturally and the two upper and lower applied layers of coating results in coating different in hue. At the part dried by spot-heating, two upper and lower layers of coating never mix together to form a pattern differing in color from the other coating part. As emulsion coating materials, acrylic emulsion coating materials are used best.

Title: Memory device
Inventor: OGISU MIKIO
IPC: G06F12/14
Filed: 1990-03-08
Abstract: PURPOSE:To efficiently use a memory by providing two pointers, which can be arbitrarily designated, to load memory protection only onto an area, which is interposed between the pointer to an unused area and the pointer to show the new area of data write, and to show the upper and lower limits of the area to be looped. CONSTITUTION:The area interposed between a current address pointer 5 and a load address pointer 4 is the unused space and when a write operation is exerted onto this space erroneously, the protection is loaded so that data can be prevented from being reloaded. The value of the current address pointer 5 is updated together with an access to the memory. By updating the value of the current address pointer 5, the stopped load of the data is restarted. When loop structure can be obtained within the upper-limit and lower-limit addresses and can be used as a temporary area, the use area can be used as the next data memory area by being successively reloaded and therefore, the memory can be efficiently used.

Title: Field effect type semiconductor device
Inventor: YAMAGUCHI HIROSHI
IPC: H01L29/78
Filed: 1987-03-11
Abstract: PURPOSE:To decrease ON resistance without decreasing the effective area of diodes, which are connected in reverse parallel, by arranging a gate wiring electrode which is extended to the central part of a power MOS chip in a snaking pattern. CONSTITUTION:Many p-type regions 2 are formed in an n<-> drain region 16 on an n<+> region 1a. An n<+> source region is formed in each p-type region 2. A gate electrode 6 is formed on each p-type region 2. Thus a vertical power MOS is constituted. A source electrode 7 is connected to the source region in a contact region 14 and also connected to the p-type region 2. Thus the potential of the p-type region 2 is fixed. The junction between the p-type region and the n<-> region acts as a reverse parallel diode between the source and drain electrodes 7 and 9. A p-type region 11 beneath a gate wiring electrode 6a is connected to the source electrode 7 and used as a reverse parallel diode. When the wiring electrode 6a is arranged in a snaking pattern, the source electrode 7 and the p-type region 11 can be connected with the region 14 even if the width d2 of the p-type region is narrow. Since the number of the region 2 can be increased in this way, the ON resistance can be decreased.

Title: Asynchronous orthogonal demodulator
Inventor: MISAIZU KIMIHIDE
IPC: H04L27/38
Filed: 1990-03-08
Abstract: PURPOSE:To realize an asynchronous orthogonal demodulator operated stably even in a transmission line where transmission line distortion due to multi-path exists without use of a reference carrier recovery circuit. CONSTITUTION:A frame format of a transmission signal consists of a 1st frequency correction symbol 1, several tens to several hundreds symbols of random series and a 2nd frequency correction symbol 2 and a data. A reception signal subjected to transmission distortion due to multi-path is detected by an asynchronous orthogonal demodulator. A frequency compensation device estimate a local oscillating frequency of the asynchronous orthogonal demodulator and a frequency offset of a reception carrier from the 1st and 2nd frequency correction symbols to compensate the phase of the detected output. A base band complex number equalizer eliminate the transmission line distortion from the detection output subject to phase correction. Through the constitution above, the demodulator is operated stably even in a transmission line having transmission line distortion due to multi-path, no reference carrier recovery circuit is required and the constitution is simplified.

IPC: C08L7/00
Filed: 1983-03-31
Abstract: PURPOSE:To improve static modulus, dynamic modulus and resistance to fatigue and fracture, by incorporating a higher fatty acid cobalt salt in rubber. CONSTITUTION:0.1-8pts.wt. cobalt salt of a 20C or higher fatty acid is blended with 100pts.wt. rubber. Examples of the rubbers are natural and synthetic diene rubbers. Examples of the cobalt salts are those of arachic, arachidonic, gadoleic and erucic acids, and those of a 22-30C fatty acid are preferred. When the quantity of the cobalt salt is less than 0.1pt., a vulcanized rubber having good crack resistance can be obtd., but one having high rigidity can not be obtd., while when it exceeds 8pts., the rigidity is too high and crack resistance is greatly lowered. When the content of the cobalt salt is too high, the heat resistance becomes poor.

Title: Heat control device of air/fuel ratio sensor
Inventor: IDE KOJI
IPC: G01N27/409
Filed: 1999-03-04
Abstract: PROBLEM TO BE SOLVED: To provide the heat control device of an air/fuel ratio sensor for reducing a period where a combustion state becomes unstable due to the use of a heavy fuel. SOLUTION: When the cancellation of a door lock is detected (step 100), the start of preheating is permitted (step 104) and it is judged whether fuel used for an internal engine is a heavy fuel or not (step 106). When fuel used for the internal engine is a nonheavy fuel, a target temperature Tc is set to T2 (step 110). When the fuel used for the internal engine is a heavy fuel, the target temperature Tc is set to T1 that is higher than T2 (step 108). Then, the amount of conduction to the heater is controlled so that the sensor temperature T can reach the target temperature T1. As this result, when the heavy fuel is in used, the sensor temperature T reaches an activation temperature faster and the air/fuel ratio feedback control is started readily.
