Title: Fixing structure of gear
Inventor: KATO TAKEO
IPC: F16H57/021
Filed: 1995-05-16
Abstract: PURPOSE: To simplify processing of each part and to reduce the number of parts by a method wherein an engaging groove is formed in the side, on the side adjoining a second gear, of a first gear and a claw part for detent engageable in a rotation direction with the engaging groove of the first gear is formed on the side, adjoining the first gear, of the second gear. CONSTITUTION: A plurality of radial oil grooves are formed in the side, on the side adjoining a drive speed gear 32, of a parking gear 30 and one of a plurality of the radial oil grooves forms an engaging groove 30a. A claw part 32a for a detent formed on the side, on the side adjoining the parking gear 30, of the drive speed gear 32 is integrally rotatably engaged with the engaging groove 30a. A means for a detent comprises the engaging groove 30a of the parking gear 30; the claw part 32a for a detent of the drive speed gear 32; and a bearing member 14 to regulate movement in an axial direction opposite to the parking gear 30 of the drive speed gear 32 and to a position where the engaging groove 30a and the claw part 32a for a detent are disengaged from each other.

Title: Float pump
Inventor: ITOU TAKASHI
IPC: F04D13/06
Filed: 1979-09-12
Abstract: PURPOSE: To prevent the generation of cavitation by ledding the mixed air outside from the suction passage part with an up-grade from the upper part of the suction port of a vane wheel, because the suction port of the vane wheel is oriented upward and there is not the shaft of the pump at that part.  
     CONSTITUTION: When dust and oil are transported and gathered on the water surface, they are not transported so rapidly due to resistance. However, due to the slow entrance speed at the suction passage part 1d, waste and oil flow into continuously, and come near the opening part 1f, where the air contained in the waste which is drawn into water flees into the air from the space part which is formed on the lower surface of an upper conical body 1a. Moreover, as a vane wheel 8 is positioned upward below the base part of the suction passage part 1d, the little air left in fluid frees upward along the wall surface of the upper conical body 1a from the upper part of the opening part 1f, and troubles such as the generation of cavitation in the vane wheel 8 due to air mixture can be prevented.

Title: Double heat transfer pipe type heat exchanger
Inventor: KUWABARA KAZUHISA
IPC: F28F11/00
Filed: 1987-05-14
Abstract: PURPOSE:To reduce the stress of a pipe, by a method wherein, in a double heat transfer pipe type heat exchanger used for a steam generator for a fast breeder, a removable flange is located between a flange mounted to a tube plate for an inner pipe and a flange mounted to a pipe tube for an outer pipe. CONSTITUTION:An outlet tube plate 8 for an inner pipe and an outlet tube plate 10 for an outer pipe are interconnected through an intermediate flange 21 to form a leak detecting fluid outlet plenum 17. Namely, a flange is formed by an upper flange 22, an L-shape intermediate flange 21, and a lower flange 23. Between the adjacent flanges, one or a plurality of gaskets 24 and 25 are fastened together by means of a bolt and a nut for sealing. The distance between the intermediate flange surfaces is hardly changed, but the upper and lower flanges 22 and 23 are deformed, and elongation can be absorbed. This constitution prevents production of a high stress at an inner pipe 12a due to an elongation difference occasioned by thermal expansion during operation.

IPC: B32B27/40
Filed: 1988-05-17
Abstract: PURPOSE:To contrive the elevation of mechanical strength and the improvement of resistances to heat, water, moisture, fungus and the like, by a method wherein the degree of orientation, obtained from the Young's modulus of a multi-layer film consisting of the lamination of ether thermoplastic polyurethane resin films, is specified. CONSTITUTION:A multi-layer polyurethane film 1 is produced by laminating ether polyurethane resin layers 3 on one side or both sides of a layer 2 consisting of the ester polyurethane resin. The thickness of the ester polyurethane resin film layer 2 occupies preferably 30-95% or 40-80% preferably when various properties such as resistance to water, moisture, fungus and the like of the multi-layer film and the economic property of the same are considered. The degree of orientation, obtained from the Young's modulus of the multi-layer film, should be 10-70% or preferably 20-60%. When the degree of orientation of the film is low and the strength of the same is insufficient, the thickness of the film should be thicker than a necessary thickness and, therefore, a trouble such that flexibility property and moisture permeating property which are proper to the polyurethane film are spoiled remarkably may be generated.
