Title: Die structure for disk molding
Inventor: ASAI IKUO
IPC: B29L17/00
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To reduce the damage of a mirror plate, increase the durability, and improve the productivity by inserting a protective sheet comprising a metal thin plate or a rigid plastic, between the rear surface of a stamper and the surface of a mirror plate. SOLUTION: The molding of a disk molded article is performed by inserting a protective sheet 30 between the rear surface of a stamper S and the surface of a mirror plate 22. By this method, a nickel separation of the stamper S, which generates due to an impact by the injection pressure of a resin material, does not adhere to the surface of the mirror plate 22, and adheres to the protective sheet 30. Therefore, the separated nickel is prevented from sinking into the mirror plate 22, and the generation of an unevenness is suppressed, and the durability of the mirror plate 22 is improved.

IPC: F02F1/08
Filed: 1982-03-04
Abstract: PURPOSE:To increase the output of the engine, to improve the durability of the cylinder  and to reduce noises from the piston by a method wherein the inner peripheral surface  of the projecting section of the cylinder sleeve on the side of the crank chamber is tapered outward at the ordinary temperature so that the inner diameter of the sleeve  becomes larger, to thereby keep precisely the roundness of the sleeve when the engine  is operated at high temperature. CONSTITUTION:The lower end of the cylinder sleeve 14 projects into the crank chamber  24 and the inner peripheral surface of the projecting section 26 is tapered outward  toward the lower end thereof at the ordinary temperature so that the inner diameter  of the section 26 is enlarged slightly. With the above structure, when the cylinder 10 is  heated to an elevated temperature with the operation of the engine, the body 12 of the  cylinder and the sleeve 14 expand but sine the coefficient of expansion of the body 12  is larger than that of the sleeve 14, the stationary section 28 which had been compressed elastically tends to return to the condition before it was compressed, so as to  follow the expansion of the body 12. As a result, the amount of increase of the inner  diameter of the stationary section 28 becomes larger than that of the projecting section 26 so that the degree of roundness of the inner peripheral surface of the sleeve 14 is improved when the cylinder 10 is heated to a high temperature.

Abstract: PURPOSE:To obtain an excellent image by exposing a non-image part of an image carrier in a beltlike shape and cleaning the image carrier without development. CONSTITUTION:The non-image part which precedes the front head of an image part is exposed in the beltlike shape right before the periphery of a photosensitive drum 10 is exposed to an image with a color signal, thereby forming a long beltlike electrostatic latent image surface. The exposed part passes through a transfer part 160 without being developed and a potential gap part is developed with waste toner atop of a blade 91 in the stage wherein the cleaning blade 91 is pressed against the drum 10. The waste toner sticking on the blade 91 as a result is transferred to the non-image part of the drum 10 and removed and in this cleaned state, cleaning operation is carried out. This waste toner is removed and collected by the blade 91, so the cleaning operation is efficient and deterioration in quality due to the resticking or residing is precluded to obtain in the color image of high quality.
