Abstract: PURPOSE:To make a sufficient seal effect obtainable by extending an annular protrusive part of a labyrinth seal mechanism in a radial direction. CONSTITUTION:A labyrinth seal mechanism 38 is provided with an annular protrusive part 40 provided in a rotor 4 and an annularly recessed part 42 provided in a housing 2. The annular protrusive part 40 is integrally provided in a yoke member 24, and the two protrusive parts 40 are arranged, providing a space in a vertical direction, in the peripheral surface of the yoke member 24. Two annularly recessed part 42 are arranged, with a space in a vertical direction in the internal peripheral surface of a protrusive wall 8 of the housing, corresponding to the annular protrusive part 40. Since the annular protrusive part 40 is extended in a radial direction and accepted by the annularly recessed part 42 restrictively provided in the housing 2, air, brought into contact with and approaching a surface of the annular protrusive part 40, is moved outward in the radial direction by centrifugal force and confined in the annularly recessed part 42 by rotating the rotor 2, and in this way, a pressure of an air layer in the bottom part of the annularly recessed part 42 is increased. Thus, a labyrinth seal of high seal effect is obtained.

Filed: 1985-06-17
Abstract: PURPOSE:To enable the omission of the patterning step for forming a contact part of a cell plate electrode by connecting the cell plate electrode and a semiconductor substrate electrically in a predetermined region at the bottom of a groove. CONSTITUTION:After removing a silicon thin film 13, a silicon oxide film 2 is formed on a surface of the silicon thin film 13 and the remaining part forms a groove 121. Next, P-type impurity such as boron is doped to deposit a silicon thin film 30 with an increased conductivity. At this time, the groove of a cell part is filled with the silicon thin film 30, but the groove in a predetermined region is prevented from being filled. The silicon thin film 30 is etched to leave the silicon thin film 30 inside the groove 121 in the cell part and also to leave the silicon thin film 30 only on the side walls of the groove 121 in a predetermined region. The remaining part forms the groove 122. Next, the silicon oxide film 4 exposed at the bottom of the groove 122 in a predetermined region is removed with a buffer hydrofluoric acid solution to expose a surface of the silicon substrate 1 in a region 14' at the bottom of the groove 122. Then, a silicon thin film 31 including P-type impurity such as boron is deposited, and is etched to fill the groove 122 completely.

Title: Control device for engine
Inventor: HOSHIBA AKIHIKO
IPC: F01M1/20
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To prevent the malfunction of an alarm control for improving the durability of an engine by setting the working pressure of a hydraulic switch for detecting the oil pressure of a hydraulic circuit higher than the lowest oil pressure for maintaining the engine in the lowest driving state. SOLUTION: An oil in an oil pan 29 is regulated in a pressure regulating valve 34 through an oil strainer 35 and an oil pump 33 and returned to a surplus oil pan 29. The regulated oil circulates a cam shaft 24 from a crank shaft 23 through an oil path Y inside the engine, and then returns to the oil pan 29. An upper part of the crankshaft 23 is provided with a hydraulic switch 36 functioning under the oil pressure in an oil path. The working pressure of the hydraulic switch 36 is setted higher than the lowest oil pressure for maintaining the engine in the lowest driving state. Thus the continuous operation of the engine below limit oil pressure at high rotation is prevented. A piston ring, bearings for the crankshaft and a cam shaft can therefore be prevented from wearing for improving the durability of the engine.

Title: Range hood
Inventor: HAGIWARA TADASHI
IPC: F24F7/06
Filed: 1990-05-21
Abstract: PURPOSE:To perform an efficient collection of oily smoke, exhaust gas and water vapor or the like without being leaked from a main body of a range hood and to prevent a trouble of a front plate driving device by a method wherein the front plate driving device is installed at a top plate of the main body of the range hood. CONSTITUTION:As an operation switch of a main body 1 of a range hood is turned on, air on a gas table is inducted into a main body 1 of the range hood 1 under an operation of an air blower 2. Concurrently, a front plate driving electric motor 7 is rotated normally, its rotating movement retracts a supporting rail 6 rearwardly through a pinion 8 and a rack 9. Since the supporting rail 6 is connected to a part higher than a supporting point 4 for the front plate, a lower end of the front plate 3 is pushed out forwardly in a reverse direction. As the supporting rail 6 is moved by a predetermined distance, a limit switch 12 turns off a power supply for a front plate driving electric motor 7 and stops the moving action of the supporting rail 6. In this way, the ascending oily smoke, exhaust gas and water vapor or the like are sucked into the main body 1 of the range hood. The oily smoke or the like are efficiently collected by the front plate driving device 10 installed at a top surface of the main body 1 of the range hood 1.
