A record material utilizing the color forming reaction between a substantially colorless chromogenic material and an electron accepting reactant material is disclosed. The colorless chromogenic material used comprises a mixture of the first component consisting of at least one specified phthalide compound having two vinyl linkages and the second component of another kind of chromogenic material which is different from said first component. The first component of the chromogenic material is used in an amount of 5 to 80%, preferably 7 to 50%, by weight with respect to the amount of the second component and in such an amount that the reflectance at any wavelength within the range of 580 nm to 880 nm, preferably within the range of 500 to 880 nm of color images developed by said color forming reaction is less by at least 55% than that of said record material before color developing.
摘要:
A carrying system for carrying a lead frame of a semiconductor device includes first and second carriers located on the same side of a carrier line, one carrier located above the other carrier. The first and second carriers are movable from along the carrier line, from a start point to a processing area and to an end point. The first and second carriers each include a holder for holding the lead frame on a specific end of the lead frame. By holding the lead frame on the same side of the carrier line and at a specific end of the lead frame, holding position deviation is minimized.
摘要:
A developing unit of the present invention includes a case which accommodates toner containing pigment, a developing roller, a supply roller formed of an elastic member arranged to be pressed against a surface of the developing roller in such a manner as to supply toner to the surface of the developing roller. The toner is mixed by conveying fins which have phases that are different in such a manner that the loads are uniform in rotation

The developing roller, supply roller, and conveying fin for each developing unit are angularly arranged in a particular manner.
摘要:
In a heat sensitive recording material comprising a substrate and a heat sensitive recording layer thereon containing a colorless or light-colored basic dye and a color acceptor which is reactive with the dye to form a color when contacted therewith, the recording material characterized in that an emulsion containing complex particles of colloidal silica and at least one of acrylic polymer and styrene-acrylic polymer is added to a coating composition for the recording layer and/or a coating composition for a protective layer formed on the recording layer.
摘要:
A developing unit of the present invention includes a case which accommodates toner containing pigment, a developing roller, a supply roller formed of an elastic member arranged to be pressed against a surface of the developing roller in such a manner as to supply toner to the surface of the developing roller. A conveying fin is supported by the case so as to convey toner to the surface of the supply roller wherein the developing roller, the supply roller, and the conveying fin are sequentially disposed in a horizontal direction. The number of revolutions of the conveying fin per unit time is between {fraction (1/50)} and {fraction (1/20)} of the supply roller.
