摘要:
A member for developing electrostatic latent images to visible images of a support having a first coating layer of an elastic material formed on the support, and a second coating layer of a flexible resin formed on the first coating layer, both coating layers having a volume resistivity of 10.sup.6 -10.sup.11 .OMEGA..cm. Such member is used in an apparatus in conjunction with a developer holding device, a developer supplying system, and a developer regulating element for regulating the thickness of the developer.
摘要:
An intermediate transfer medium including a layer which includes an acidic carbon black including volatile components of from 3.5 to 8.0% by weight; at least one of a water soluble resin having a weight average molecular weight of from 3,000 to 30,000, and a resin dispersant having a weight average molecular weight of from 3,000 to 300,000 which is selected from the group consisting of polyamide acids, polyimides, and block copolymer including a unit containing at least one of a polyamide acid and a polyimide; and a binder resin, wherein a weight ratio (CB/R) of the carbon black (CB) to the at least one (R) of the water soluble resin and the resin dispersant is from 3/1 to 10/1. A film forming liquid for use in preparing the layer, and an image forming apparatus using the intermediate transfer medium are also provided.
摘要:
A rotor for a reluctance type rotating machine includes a rotor core formed by stacking a number of annular core materials each of which includes magnetic concave and convex portions alternately formed on an outer circumference thereof and a central through hole, the rotor core having a key axially extending on an outer circumference thereof, the rotor core being divided into a plurality of blocks, the core materials constituting at least one block having the magnetic concave and convex portions shifted by a predetermined angle relative to the core materials constituting the other or another block on the basis of a center line passing the key, and a rotational shaft inserted through the central hole of the rotor core, the shaft having a key groove engaging the key of the rotor core.
摘要:
The invention relates to a process of preparing pellets of a synthetic organic fiber reinforced polyolefin and discloses the process in which the reinforcing fiber is impregnated with the molten polyolefin. The invention is characterized in that the sufficient impregnation can be carried out by selecting the polyolefin and the synthetic organic fiber having the appropriate melting points and controlling the temperature of the molten polyolefin to minimize the heat deterioration of the synthetic organic fiber. The pellets obtained by the process of the invention provides a molded product having superior impact resistance and recyclability when used as raw materials for injection molding, injection-compression molding, extrusion, blow molding and a like molding process.
