Title: Steering wheel
Inventor: SATO EIJI
IPC: B62D1/04
Filed: 1993-03-03
Abstract: PURPOSE:To prevent the occurrence of defects such as poor cavities in a polyurethane-foamed cladding moulded around a more by reaction injection molding under pressure reduction in a steering wheel. CONSTITUTION:In the ring part 7 of a core 2, a narrow-diameter part 10 formed on the end of a solid material 9 is inserted in the end of a pipe material 8 and a calking part 12 is formed on the end of the pipe material 8. The calking part 12 is pressed against the narrow-diameter part 10 to hermetically seal the inner part of the pipe material 8 and to increase the joining strength of the pipe material 8 and the solid material 9. The core is set in the cavity of a mold and pressure in the cavity is reduced. In molding a polyurethane-foamed cladding, air in the inner part of the pipe material 8 is left to be confined in the calking part 12 to occur no defects such as poor cavities in the polyurethane-foamed cladding.

Title: Joining of head and footing of concrete pile
Inventor: NAKAJIMA YASUO
IPC: E02D27/12
Filed: 1982-04-23
Abstract: PURPOSE:To prevent the breakage of the head of a pile to be caused by the earthquake by a method in which a fixing bar is vertically provided at the spherical top of the pile head, and concrete for footing is placed above the spherical face of the pile head so as to join the head and footing of the pile through only the fixing bar. CONSTITUTION:A spherical metal 4 having a fixing bar 3 erected at its top is fixed to the top plate 2 of the pile 1 penetrated into the ground, and then a frictional force-reducing treatment using asphalt, etc., is applied to the pile head S to form a frictional force-reduced layer (a). Then, concrete for footing 10 is placed above the pile head S to join the head S and the footing 10 through only the fixing bar 3. By this, the frictional force between the pile head S and the footing 10 is reduced by the layer (a) to form a pin-joint and thereby the relative movement between the pile head S and the footing 10 by horizontal force caused by earthquake is made possible and the load to a structure on the ground's surface is diffused over the whole area of the pile head S, thus preventing the local breakage of the pile head.

Abstract: PROBLEM TO BE SOLVED: To shorten data updating time by compressing new data in the case of the length of new data being longer than the length of old data, and writing the compressed new data in a written area of old data in a storage medium. SOLUTION: At the time of updating data on a storage medium 13, a data number assignment signal is supplied from the outside. An address control device 16 reads a data start address from an address storage device 15 and outputs it to an address generator 14. The address control device 16 reads a data termination address and outputs the obtained writable memory quantity on the storage medium 13 to a compressibility control device 17. The compressibility control device 17 outputs compressibility, obtained by dividing the writable memory quantity by the data quantity in a buffer 11, to a coder 12. The coder 12 codes data in the buffer 11 by compressing at this compressibility, and the storage medium 13 records new data compression-coded by the coder 12.

Title: Manufacture of polyester moldings
Inventor: KAWAKAMI KAZUMI
IPC: B29C51/00
Filed: 1997-03-24
Abstract: PROBLEM TO BE SOLVED: To improve glare proof as the translucent cover of an illuminator by spreading a liquid droplet to a polyester sheet to make a surface temperature non-uniform and thereby reducing the glossness of the surface below a specified level. SOLUTION: When thermally forming a polyester sheet, it is rapidly cooled by spreading a microliquid droplet to the surface to make the surface temperature delicately non-uniform. Thus the surface glossness of moldings is lowered to 90% or less. Polyester is composed of an aromatic dicarboxilic acid component and a glycol component, and terephthalic acid is used as the aromatic dicarboxylic acid. In addition, from the viewpoint of the thickness uniformity and the deep drawing properties of the sheet, the temperature of a casting drum is preferably 0-80 deg.C. Further, the thickness of the polyester sheet is normally 0.05-10 mm, and the spreading of the liquid droplet is preferably performed while the surface temperature of the polyester is as hot as 80 deg.C or higher. In this case, the liquid droplet of 10-500 g/m<3> creates an atomization state.

Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To increase durability by arranging a reinforcing layer that is harder than a resin material comprising a ski cap integrally in an area near a screw insertion hole. SOLUTION: For instance, a ski cap 1 is formed integrally of a polyamide resin elastomer whose Shore D hardness is about 62, nearly in triangular form as viewed from top. A head insertion section for a ski 8 is formed inward from the rear end. Screw insertion holes 6a, 6b are made in a top wall 4 and a bottom wall 5 in positions about 15mm from the rear end toward the head of the ski cap 1. Concentric reinforcing layers 7 around the screw insertion holes 6a, 6b are arranged in the surrounding of the insides of the screw insertion holes 6a, 6b that contact a ski 8. The reinforcing layers 7 are formed of a material harder than the component material of the ski cap 1, a polyacetal resin whose Shore D hardness is about 75 for example. The increased rigidity of the surrounding areas of the screw insertion holes 6a, 6b protects the ski against deformation and cracking.
