Title: Oil cooler device for engine for vehicle
Inventor: TAKAOKA YOSHIO
IPC: F01P11/08
Filed: 1985-10-29
Abstract: PURPOSE:To cool oil simply and securely by providing plural number of cooling air port parts vertically passing through a rear spoiler, while housingly providing an oil cooler having cooling fins in positions corresponding to said cooling air port parts inside acid rear spoiler. CONSTITUTION:When a vehicle is traveling, air flows at a high speed along the top surface 3b and the bottom surface 3c of a rear spoiler S and, due to the wing shape of a body 3a, negative pressure is generated on the bottom surface 3c. Thereby, part of air flowing on the top surface 3b passes through the inside of the spoiler body 3a through port parts 8, 8 due to pressure difference. As a result, oil which passes through the meandering passages 6b of an oil cooler 6 is effectively cooled by cooling air, by means of fins 6a. Thereby, the oil can be cooled simply and securely using running wind. Also, since the oil cooler 6 is provided on the outside of an engine room, an extra space can be secured in the engine room.

Title: Infrared-ray analyzer
Inventor: UEDA TOSHITSUGU
IPC: G01N21/61
Filed: 1983-12-22
Abstract: PURPOSE:To perform highly accurate analysis, by providing a fixing plate having slits, providing a movable plate, which is supported by two points on a straight line passing the center of gravity and can be rotated, detecting the difference in pressures, thereby making it hard to receive the effect of vibration noises and posture change. CONSTITUTION:Infrared rays, which have passed a sample cell 1 and a comparing cell 2, are inputted to light receiving chambers 51 and 52, and pressures P1 and P2 are generated. Said pressures P1 and P2 are supplied to a pressure measuring means 6, and the pressure difference P1-P2 is detected. The measuring means 6 is provided with a fixed plate 70 having slit holes and a movable plate 92, which is arranged so as to face the fixed plate and supported by a supporting port 93 at two points on a straight line passing the center of gravity. In this constitution, the movable plate 92 is slanted by an angle proportional to the pressure difference P1-P2. The displacement of the movable plate 92 is measured as the change in electrostatic capacity. Thus the difference between the pressures P1 and P2 can be detected. Since such a pressure measuring means is hardly affected by vibration noises and attitude change, highly accurate analysis can be performed.

Title: Semiconductor and manufacture thereof
Inventor: HAGIWARA YOSHIMI
IPC: H01L21/331
Filed: 1997-09-09
Abstract: PROBLEM TO BE SOLVED: To improve the withstand voltage without deteriorating characteristics, by setting to specified value or more the base width of a bipolar transistor vertically formed on a semiconductor substrate main plane, which is the (100) plane of a semiconductor single crystal or near it. SOLUTION: An emitter region 5, base region 4 and low-concn. collector region 3 are formed in the depth direction of a semiconductor substrate from its main plane, adopting the (100) plane of a single crystal Si as the main plane, so that the base region width Wb between the bottom of the emitter region 5 and top of the collector region 3 is 5 μm or more. This provides a smaller Si atomic index per unit cross section than that when the semiconductor substrate main plane takes the (111) plane, hence the minority carrier life becomes long to result in reduction of the influence caused by broadening the base width, and the current amplification factor never abruptly lowers.
