Abstract: A development roller of an electric-photographic machine is manufactured by a method of mixing a base material of either NBR rubber or HYDRIN rubber, an electric conductive high-molecule-weight material to adjust an electric resistivity of the development roller, and peroxide as a cross-link agent cross-linking the base material and the electric conductive high-molecule-weight material in a three-dimensional structure, forming the development roller from a mixture of the base material, the electric conductive high-molecule-weight material, and peroxide, and irradiating the development roller with ultraviolet light to adjust a friction coefficient of a surface of the development roller. Accordingly, the development roller has characteristics of a low electric resistivity even with a single layer structure.

Abstract: A monolithic inkjet printhead formed using integrated circuit techniques is described. A silicon substrate has formed on its top surface a thin polysilicon layer in the area in which a trench is to be later formed in the substrate. The edges of the polysilicon layer align with the intended placement of ink feed holes leading into ink ejection chambers. Thin film layers, including a resistive layer, are formed on the top surface of the silicon substrate and over the polysilicon layer. An orifice layer is formed on the top surface of the thin film layers to define the nozzles and ink ejection chambers. A trench mask is formed on the bottom surface of the substrate. A trench is etched (using, for example, TMAH) through the exposed bottom surface of the substrate and to the polysilicon layer. The etching of the polysilicon layer exposes fast etch planes of the silicon. The TMAH then rapidly etches the silicon substrate along the etch planes, thus aligning the edges of the trench with the polysilicon. A wet etch is then performed using a buffered oxide etch (BOE) solution. The BOE will completely etch through the exposed thin film layers on the topside and underside of the substrate, forming ink feed holes through the thin film layers. The trench is now aligned with the ink feed holes due to the polysilicon layer.

Abstract: The present invention provides an elastic body having a small volume change caused by the change in temperature, a roller having a small change in outer diameter thereof caused by an increase in temperature of the roller during operation, a manufacturing method therefor, and a heating and fixing device which can maintain a constant processing speed. The roller has an elastic layer formed by curing a silicone rubber material containing at least expanded resin microballoons, wherein, when the roller is placed in a vacuum chamber in which atmospheric pressure is reduced to 0.001 MPa or less over 2 minutes, the roller has a gas permeability indicating the recovery characteristic where an increased amount of the thickness of the elastic layer after 10 minutes from the start of evacuation is two-thirds or less of the maximum increased amount of the thickness of the elastic layer during a 10 minutes period from the start of evacuation. The elastic layer is formed by curing a silicone rubber material containing the expanded resin microballoons and has air void portions formed by breaking the resin microballoons and passages connecting the air void portions therebetween. The heating and fixing apparatus provided with the roller and the method for manufacturing the roller are also disclosed.

Abstract: A hollow rack shaft is manufactured through a first step, a second step and a third step. At the first step, the plate-like workpiece of substantial rectangular shape is press formed into a gutter-like shape. The first die set used at this step is provided with slant die surfaces for canceling elastic recovering generated at the workpiece when the workpiece is removed from the first die set. At the second step, a row of rack teeth is press-formed on the flat bottom portion of the workpiece formed in the first step. The die set used at the second step is provided with a recess for releasing surplus workpiece material within the die clearance at a stroke end of the pressworking. At the third step, each of a pair of legs of the workpiece is bent in a semi-circular shape so as to be butted to each other. At this time, a mandrel is inserted between the legs of the workpiece.
