Title: Production of hollow molded product
Inventor: EBISAWA ATSUSHI
IPC: B29C49/06
Filed: 1993-07-30
Abstract: PURPOSE:To reduce the generation of the irregularity of a hollow part to a large extent by constituting the material quality of a mold forming the hollow part of a metal material high in heat conductivity. CONSTITUTION:Molds 1, 2 forming a rib 7, boss or thick-walled part having a hollow part 10 are formed from a metal material with heat conductivity of 85W/m.K or more, for example, zinc, Be-Cu, aluminum, copper, an alloy based on them or a material plated with them. By using the metal material low in heat conductivity, the molten resin of the thin-walled part of a general surface other than the rib 7, the boss or thick-walled part having the hollow part 10 is rapidly cooled and solidified. By increasing the viscosity of the molten resin of the thin-walled part, the viscosity difference of the resin with the place where the hollow part 10 of the rib 7, boss or thick-walled part is desired to be formed is increased to make it possible to selectively inject gas only into the rib, boss or thick-walled part low in viscosity.

Abstract: PROBLEM TO BE SOLVED: To excellently transfer an image even to thick recording paper from a photoreceptor drum by providing a sheet guiding means so that it can move to a position where a sheet is guided while it is pressed to an image carrier. SOLUTION: The recording paper is separated from the surface of the photoreceptor drum by a separator and guided to a fixing device by the sheet guiding means 14 (recording paper guiding means). The guiding means 14 is constituted of a 1st recording paper guiding member 41 and a 2nd recording paper guiding member 40. The guiding member 41 is provided with a function for merely guiding the recording paper and a mechanism for preventing transfer deviation by moving upward and pressing the thick recording paper to the surface of the photoreceptor drum when the thick recording paper is used. The guiding member 40 is provided with the function for merely guiding the recording paper, while it can be provided with a function for facilitating jamming processing by moving downward.  Thus, the guiding means 14 moves to the position where the sheet is guided while it is pressed to the image carrier.

IPC: B28D1/24
Filed: 1991-07-26
Abstract: PURPOSE:To enhance the accuracy of cutting processing to a large extent by a method wherein a work is sent to the outer periphery of a flexible disc-shaped blade rotating at a constant position while vibration of a low frequency region is imparted to the work in the same direction as the cutting direction of the work or the direction crossing said cutting direction at a right angle to be cut. CONSTITUTION:A work 9 is sent to the outer periphery of a flexible disc-shaped blade 10 rotating at a constant position while vibration of a low frequency region is imparted to the work 9 in the same direction as the cutting direction of the work or the direction crossing the cutting direction at a right angle to be cut. Therefore, cutting and separation are alternately repeated between the outer peripheral edge of the disc-shaped blade 10 and the work 9 by the vibration of the work 9 and cutting resistance is reduced. Even when offset abrasion is generated in the outer peripheral edge, no bending cutting is generated by applying vibration to the work and highly accurate linear cutting becomes possible.
