Title: Press for manufacturing plastic blank
Inventor: UIRII SHIYUMITSUTO
IPC: B28B17/00
Filed: 1989-03-29
Abstract: PURPOSE: To continuously extrude a blank without generating a spiral eye or an inner twist by concentrically bearing a rotor in a rotor housing, forcibly controlling a peeling knife provided at an upper end of an outlet sector part, and raising it so as not to be barely brought into contact with the rotor. CONSTITUTION: A circular rotor 3 is concentrically borne, and a rotor housing 2 is preferably in a cylindrical shape. A material is conveyed from a vacuum chamber 6 toward a die 5. And, the material compressed in a material conveying segment 7 is released from the rotor 3 by a peeling knife 13 provided at an upper end of an outlet sector part 15 at each time. To prevent a disadvantageous metal galling, the knife 13 must be considered so as not to be barely brought into contact with a surface of the rotor. A gap is 0.05 to 2 mm or particularly desirably 0.3 to 0.5 mm. this is performed by forcibly controlling the knife 13. The knife follows a surface contour of the rotor at a predetermined distance by the forcible control.

Title: Method for welding stainless steel sheet
Inventor: OKATO NOBUYOSHI
IPC: B23K9/235
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To perfectly prevent the generation of stains in a steel sheet at the time of welding and pickling, as the stock for a stainless steel sheet for welding, by using the one whose surface is coated with a chromium depleted layer. SOLUTION: As the stock for welding, the one in which only annealing oxidized scales on the surface of an austenitic stainless steel sheet is removed and a chromium depleted layer is allowed to remain is used. The thickness of the chromium depleted layer is regulated to 0.5 to 30μm. In the part in which stains are generated by pickling after welding, fine pits are formed in the grains. The diffused reflection of light formed by the pits is the cause of the stains. By the difference in the surface temp. of the stainless steel at the time of the welding, there occurs the difference in the structure of welding scales to form pits.  In the case the welding scales are pickled after the welding and are dissolved away, together with the welding scales, the chromium depleted layer directly below the same is uniformly and simultaneously removed to prevent the generation of pickling strains. The surface properties of the stainless steel sheet after the welding can be improved remarkably compared to those of the conventional one.
