Title: Seal material
Inventor: UEMORI KAZUYOSHI
IPC: B65D53/04
Filed: 1982-04-30
Abstract: PURPOSE:To firmly joint both a sheet and a layer, by integrally forming the thermoplastic resin foamed layer by welding to one side of the polytetrafluoroethylene sheet in which numerous fine protrusions are formed by a sputter etching of a PTFE sheet 3 process. CONSTITUTION:A foamable layer is firstly formed to a surface processed by sputter etching and then this layer is converted to a foamed layer 2. In this way, not only the uniform layer 2 can be formed but also a seal material, in which the sheet 3 and the layer 2 are integrally formed strongly by welding, can be obtained. The reason why joint strength between the sheet 3 and the layer 2 is increased is attributed to that the surface area of the sheet 3 is increased by fine protrusions generated on the surface of the sheet 3 due to a sputter etching processing while the fine protrusions formed on the sheet surface display an anchoring effect.

Filed: 1995-03-30
Abstract: PURPOSE: To eliminate damage of an image bearer and enhance the image quality by furnishing a buffer means to relieve the shock at contacting of a photoreceptor drum with a charging roller. CONSTITUTION: A photoreceptor drum is charged negatively under the action of a charging roller 2 on which a voltage is impressed, and then electric charges on a non-character part are removed through the action of a photo-exposure device 3, and an electrostatic latent image is formed on the drum 1. If a contacting/separating solenoid 16 is deenergized when the charging roller 2 positioned separately is to be put in pressure contact with the drum 1, a disengaging lever 17 rotates vigorously counterclockwise with an energizing force of a pressurizing spring 15, but the energy is reduced when it runs against a buffer member 18 made of sponge furnished on a mounting bracket 19.  According to this constitution in which the charging roller 2 contacts with the drum 1 after the revolving speed of the disengaging lever 17 has sunk sufficiently, the roller 2 runs against the drum 1 vigorously, which precludes a risk of the drum 1 being damaged.
