Title: Continuous extrusion method for metal
Inventor: AWAI KIYOSHI
IPC: B21C23/21
Filed: 1978-04-24
Abstract: PURPOSE: To apply the lubricant to the surface of the die and the metallic material, and to extrude the good product free from the surface defect, by feeding the metallic material entirely coated with the thermoplastic synthetic resin, into the rotary wheel type continuous metal extruder.  
     CONSTITUTION: The entire surface of the metallic material 6 is coated by deposition, etc., with the thermoplastic resin like as PP, PE, etc., for instance. When this coated metallic material 6 is fed into the path formed between the outer circumferential groove 2 of the rotary wheel 1 and the stationary shoe of the extruder, the wheel 1 is being cooled and is restricted to a low temperature at neighborhood of the entrance of the path, so that the coated resin does not melt there; as a result, the friction force between the coated resin and the circumferential wall of the path does not reduce, and the metallic material 6 goes forward through the path. In front of the projection 4 within the path, a high pressure and high temperature condition is kept, so that the coated resin melts there, and gives the lubrication to faces of the extrusion die 5 and the metallic material 6; as a result, the extruded product 7 with good surface condition can be obtained.

Title: Method for machining diamond
Inventor: OTA YUKIHIRO
IPC: C04B41/80
Filed: 1993-03-10
Abstract: PURPOSE:To enable high precision cutting and surface smoothening of diamond without affecting the body of the diamond to be machined and to increase the rate of machining. CONSTITUTION:Diamond is machined by irradiating the surface with light whose wavelength is within the range of 190-360nm. The energy density of the light, the divergent angle of beams and the half-width of a spectrum are regulated and the beams are converged through a cylindrical lens. When machining is carried out in a specified substance, the smoothness of the machined surface is improved and the rate of machining is increased. The application range of diamond can be extended to a field in which diamond cannot be used because of difficult machining or very high cost.
