Abstract: PURPOSE:To speedily perform bending piping work, prevent dewing, and enhance corrosion resistance by disposing synthetic resin layers at the inner and outer surfaces of a metal tube, forming a temperature keeping layer at the upper surface of the outer synthetic resin layer, and keeping a bending shape by permanent deformation of the metal tube. CONSTITUTION:A piping tube member A is constituted of an inner and an outer synthetic resin layers (a), (c) disposed on the inner and outer surfaces of a metal tube (b), respectively, and a temperature keeping layer (d) formed at the upper surface of the outer synthetic resin layer (c). A bending shape is held by permanent deformation of the metal tube (b). In bending the piping tube member A, a flexible core member B where no buckle due to bending can be generated is inserted into the piping tube member A and the metal tube (b) is permanently deformed by bending the flexible core member B, and then, the flexible core member B is drawn out of the piping tube member A.

Title: Preparation of aluminum composite plate for deep drawing
Inventor: IWAMA TETSUJI
IPC: B29C65/02
Filed: 1986-12-04
Abstract: PURPOSE:To give ductility suitable for deep drawing to an aluminum plate and to remove strain and deformation generated at a surface treatment, by using a hard cold-rolled aluminum plate as it is without any tempering and treating it with a heat tempering after carrying out a specific surface treatment. CONSTITUTION:A cold-rolled aluminum plate which is not treated by a tempering being usually done after cold-rolling and whose degree of tempering is H18 is used. The thickness is in the range of 0.1-0.5mm which is usually used for deep drawing. As a treating method for mechanical roughening, a sand-blast method by which roughness control is easy is practical. Then, micro bits having rectangular openings the average length of whose one side is 2-5mm are formed on the roughened surface by means of a direct current electrolytic etching. A surface having good adhesiveness with a resin coating can be obtained by the above described surface treatment. Then, require characteristics are given to the aluminum plate by heating the rolled sheet. This heat treatment can temper the plate to soften it and to improve the deep drawability and at the same time, remove deformation such as waving, warpage and so on and residual strain to obtain an homogeneous plate having good flatness.

Title: Electric vehicle and power source thereof
Inventor: WATANABE KUNIHIKO
IPC: H02H5/00
Filed: 1995-10-11
Abstract: PROBLEM TO BE SOLVED: To provide an electric vehicle and power source thereof which enable prevention of occurrence of a leak from an unspecified place even when water penetrates into the electric vehicle. SOLUTION: In a battery unit 20, a waterproof case 22 and a float chamber 26 on the lateral side of the case are provided integrally. When water begins to penetrate into an electric vehicle, it enters through a water passing port 30 formed in the bottom of the float chamber 26 and, therefore, a float 31 begins to float up. When a water level rises to a certain height, a pullcord 32 connected with the float 31 pulls a rubber plug 28 upward and pulls it out of a communication port 27. As the result, the water penetrates into the waterproof case 22 and a group of terminals 21a of a battery element 21 is put in a state of immersion. Therefore a short circuit occurs between the terminals 21a in a battery unit 20 and thus occurrence of a leak in another part can be prevented reliably.
