Title: Exhaust device for internal combustion engine
Inventor: JIYO SHIYAKUKOU
IPC: F01N3/24
Filed: 1980-08-01
Abstract: PURPOSE:To prevent the air contamination and noise of exhaust of a stationary internal combustion engine or the like for driving a heat pump and maximally recover and utilize waste heat, by coupling a catalytic reaction part, a heat exchange part and a silencing part in that order to construct an exhaust device. CONSTITUTION:A heat exchange part 4 is coupled to a catalytic reaction part 3 which is connected to the exhaust port 2 of an engine 1 as near to the port as possible. A water jacket 10 is provided around the parts 3, 4. Cooling water is introduced through an inlet port 8 so that the water absorbs the energy of exhaust gas. After that, the cooling water is drained through an outlet port 9. The energy absorbed by the cooling water is used not for the engine 1 but for some purpose. The water jacket 10 is covered with a heat insulator 11. After the exhaust gas having passed through the heat exchange part 4 is removed of water through a drainer 7, the exhaust gas enters into a silencing part 5 next to the heat exchange part 4 so that the noise of the exhaust is reduced. The exhaust gas is then released into the atmosphere through a tailpipe 6.

Title: Bearing device of small type dc motor and manufacture thereof
Inventor: KOIKE AKIRA
IPC: H02K5/167
Filed: 1997-04-08
Abstract: PROBLEM TO BE SOLVED: To reduce the manhour of assembling a bearing part largely for manufacture of a low-priced and highly accurate motor by retaining an oil- impregnated sintered bearing, which is constituted of one hollow bearing, by means of shaft formation of a bearing holder. SOLUTION: A bearing holder 6 constituted of synthetic resin is fixed on a cylindrical case 5 which forms a housing by means of integrated formation. One oil-impregnated sintered bearing 7 which is formed into a hollow shape is retained at the inner periphery of the bearing holder 6. The oil-impregnated sintered bearing 7 is not pressed in the nearing holder 6, but is integrally- retained at the resin formation of the bearing holder 6. A rotor is overhang- supported by one oil-impregnated sintered bearing 7 disposed in this way. As a result, axial perpendicularity or axial runout can be achieved with very high accuracy using a metal mold without need for much manhour of assembly. It is thus possible to manufacture the bearing device of a small type DC motor with a simple method.

Title: Semiconductor device and manufacture thereof
Inventor: AKISAWA TETSUO
IPC: H01L29/417
Filed: 1980-08-04
Abstract: PURPOSE:To enable stable operation to be obtained, by adopting a double-layered gate electrode of different materials. CONSTITUTION:An Si oxide film 12 is grown on a P type Si substrate 11. Next, a poly-Si film 13 which includes no impurity covers it. A poly-Si film 14 which includes an N type impuity is superimposed on it. Next, the poly-Si films 13 and 14 are processed to form a gate electrode. The film 12 is selectively etched by using as a mask the poly Si-films 13 and 14 to open a diffusing window 15 for a source and a drain. Then, an N type impurity is diffused from the window 15 to form a source region 16 and a drain region 17. In this case, as there is the poly-Si film, which includes no impurity, in a part facing to the regions 16 and 17, impurity in the poly- Si film 14 will not be diffused to the substrate 11. Therefore, this prevents short channel effects and the like from occurring.

IPC: G01F23/04
Filed: 1983-06-14
Abstract: PURPOSE:To determine the liquid level positively almost eliminating the wet height by immersing an inspection scale tape coated with a naphtha inspection scale agent colored by mixing a greasy material with oil-soluble dye into a volatile oil so that only the dye below the oil level is melted away to specify the point of the oil level. CONSTITUTION:A greasy material is a semi-solid or solid lubricant in which a densifier is dispersed evenly into a petrolic lubrication oil or a synthetic oil such as silicone oil. This is examplified by a petrolic grease and a silicon oil based grease (silicon grease or the like). The densifier includes soap-based and non- soap based ones. The former is a soap of calcium or the like and the latter are an inorganic compound such as bentonite, a urea compound and a fluorine compound. The oil-soluble dye refers to a dye soluble in a mineral oil, fats and fatty oils or the like but not water soluble. The amount of the oil soluble dye to be added is just enough to generate a color. The naphtha inspection scale agent is prepared by adding a fixed amount of the oil-soluble dye to the greasy material, which is heated and melted at about 80 deg.C and mixing them thoroughly. The coat of the naphtha inspection scale agent on the inspection scale tape is about 0.5g each.

IPC: G07F13/10
Filed: 1990-04-23
Abstract: PURPOSE:To secure safety without a discharge port shutter and to shorten sale time by detecting disconnection when an output port door is opened and stopping sales operation. CONSTITUTION:When a merchandise selection push-button 1 is pushed, the controller discriminates whether the sales is effective or not. A load A is electrified when the sales is effective, and the load A is operated at the timing in operation. When the sale is 'NO', the controller advances to the next step, discriminates whether it is the timing to stop the load A or not, and stops the load A at the time in the timing. When 'NO' in the next step, the controller discriminates the timing of the operation and the stop of a load B similarly to the load A. After deciding the next load successively, the controller decides whether a load A performing the final operation is in the timing in operation or not. When the load Z is in the timing in operation, the load Z is turned 'ON'. When 'NO', the controller discriminates whether it is the timing to stop the load Z or not and whether the output port door is disconnected or not, and stops the loads A-Z at the time of disconnecting.
