Abstract: The present invention provides a thermal transfer image-receiving sheet which can form a clear image having a sufficiently high density and excellent in various types of fastness, particularly durability such as light fastness, fingerprint resistance and which is plasticizer resistance according to a thermal transfer printing process wherein use is made of a heat migratable dye. The thermal transfer image-receiving sheet includes a substrate sheet and a dye-receiving layer formed on at least one surface of the substrate sheet, wherein the dye-receiving layer includes a product of a reaction of a polyoxyalkylene polyol with an organic polyisocyanate.

Abstract: A heat transfer image-receiving sheet for use in a heat transfer printing method using a sublimable dye, including (i) a substrate sheet and (ii) a dye-receiving layer provided on at least one surface of the substrate sheet. The dye receiving layer includes a polyester resin, wherein at least one of the diol component and the acid component of the polyester resin including an alicyclic compound. The heat transfer image-receiving sheet can produce a sharp image with a sufficiently high density, which image is excellent in fastness properties, in particular, in resistance to light, resistance to sebum and sweat and resistance to plasticizer.

Abstract: The present invention relates to a heat transfer recording medium in which a substrate items of information such as an image and characters formed on a surface thereof by heat transfer and a transparent protective layer is provided on at least a part of the surface of the thus recorded information through an adhesive layer, if required, characterized in that the adhesive layer and/or protective layer function to provide security against counterfeiting. Combining information recorded by heat transfer with a function to provide security against counterfeiting, the present invention provides greater security against falsifying or counterfeiting.

Abstract: A heat transfer recording medium usable for producing an image by employing thermal printing means such as a thermal head, in which a dye layer of a heat transfer sheet or a dye-receiving layer of a heat transfer image-receiving sheet comprises therein or thereon a dye-transfer promoting agent comprising a compound which is in a crystalline state at room temperature and can be fused by thermal energy which is applied when heat transfer recording is conducted.A heat transfer recording method using a heat transfer sheet and an image-receiving sheet, in which a dye-transfer promoting agent comprising a compound which is in a crystalline state at room temperature and can be fused by thermal energy which is applied when heat transfer recording is conducted is given to a dye layer and/or a dye-receiving layer before the formation of an image.

Abstract: A carburetor including an inner vent communicating with an air intake of the carburetor, an outer vent communicating with an evaporated fuel gas absorbing charcoal cannister and a float chamber. The carburetor is characterized by a connecting portion for directly connecting the inner vent and the outer vent without passing through the float chamber and an opening in the connecting portion connecting the inner and outer vents to the float chamber.

Abstract: Disclosed is a fuel supply installation for internal combustion engines, in which fluid fuel is atomized by ultrasonic vibration and which includes a fuel atomization pail provided under the bottom wall of an intake air passage and which is open to the passage. The fuel atomization pail has an ultrasonic element which is energized by high frequency electric power. The fluid fuel in the atomization pail is atomized by ultrasonic vibration of the element and is mixed with the suction air in the intake passage.

Abstract: There is disclosed a system for controlling vaporized hydrocarbon of fuel for a gasoline engine wherein the vaporized hydrocarbon is led from a carburetor float chamber to a canister through a pipe in which a chamber for separating fuel and vapor is provided.
