  • Sheet processing apparatus, image forming system and sheet processing method
    Patent number: 8490959
    Abstract: According to one embodiment, a sheet processing apparatus includes a roller unit having a reinforce roller which moves along a fold of a sheet perpendicular to the sheet conveying direction and thereby further reinforces the fold by the reinforce roller, and a control unit which counts the number of halts of the roller unit generated during the reinforcing operation of the sheet, and in case that the counted number of the halts of the roller unit is less than a prescribed number of times, makes the roller unit to be moved to a retract position and then makes the roller unit to be driven again to perform the reinforcing operation.

  • Thermal conductive silicone rubber compositions and making method
    Patent number: 6306957
    Abstract: An organopolysiloxane, a hydrolyzable group-bearing methylpolysiloxane, a thermal conductive filler, and a curing agent are blended to form a silicone rubber composition which is minimized in viscosity or plasticity increase and remains effectively moldable and workable even when loaded with a large amount of the thermal conductive filler. It cures into a silicone rubber part having a high thermal conductivity.

  • Sheet-shaped adhesive composition
    Patent number: 5942565
    Abstract: An adhesive sheet is obtained by sheeting a claylike silicone composition comprising an organopolysiloxane, a filler, and an adhesive aid to a gage of 0.1 to 5 mm. The adhesive sheet is easy to handle and bondable to such adherends as metals and plastics to exert a high bond strength.
