Abstract:
A thermal transfer color printer for printing color images on individual sheets of paper. One sheet of paper at a time is removed from a stack of paper stored in a cassette and this sheet is transported by a reversible platen roller in a first or forward direction at a first predetermined rate. While the sheet of paper is gripped between the reversible platen roller and one or more pinch rollers, slack is removed by a slack removing device. A multicolored ink ribbon with successively arranged color segments also is transported in the first direction at the same predetermined rate. A thermal printhead presses against the reversible platen roller to press the ink ribbon and sheet of paper together as they move in the first direction. Energization of the thermal elements on the thermal printhead by color component signals corresponding to the current color of the ink ribbon causes the particular current color to be thermally and selectively transferred to the sheet of paper. The thermal printhead then disengages the platen roller and the sheet of paper is transported in a set distance in a second direction opposite the first direction, and at a second predetermined rate, in order to repeat the process of thermally transferring other colors to the sheet of paper. During the back and forth movement of the sheet of paper, the reversible platen roller and the pinch rollers continuously grip the sheet of paper in order to precisely control the position of the sheet of paper to thereby avoid distortion. A complete color image is formed on the sheet of paper by superimposing the multiple colors of the ink ribbon as the sheet of paper and the different colors of the ink ribbon repeatedly move past the selectively energized thermal elements of the thermal printhead.
Abstract:
A color image printing apparatus prints one pixel by superposing a predetermined dots of three colors within a 3.times.3 dot matrix in accordance with a density of the pixel. The positions of the printed dots within the dot matrix are stored as a dot pattern for each color. One dot pattern is used for each of a plurality of densities included in one density range. The printing energy for each of the dots included in the dot pattern is controlled in accordance with the density level of the pixel. The dot pattern is different for each color and three dot patterns are stored for each color and for each density range. These three dot patterns are repeatedly used for every three pixels which are continuous in the horizontal direction. These three dot patterns have two or three texture directions. The texture direction other than the vertical direction is different for each color.
Abstract:
Process for producing a completely random copolymer of a conjugated diene and a monovinyl substituted aromatic compound having the same composition as that of the starting monomeric mixture which comprises copolymerizing a conjugated diene and a monovinyl substituted aromatic compound in the presence of lithium catalyst in a polymerization medium at a temperature not higher than 150.degree. C and at which the resulting copolymer is substantially phase-separated, said temperature being dependent upon the type of medium, and type, composition and concentration of the monomer used.
Abstract:
Provided are a gas turbine multi-hole film-cooled combustor liner, which can be manufactured with improved accuracy in shape and position of cooling holes in a very short time, ensuring desirable buckling strength and satisfactory cooling performance. A planar flat member is curved to form a liner shell of a cylindrical shape, the cylindrical member is welded in the longitudinal direction thereof to form a cylindrical shell. Then a wavy configuration and a corrugated configuration are formed on the cylindrical shell by a hydro-bulging method, cooling holes are formed through the liner shell by laser drilling at or near wave crest portions of the wavy configuration of the liner shell, and inner rings are attached to the liner shell by resistance spot welding or vacuum brazing.
Abstract:
Pipe fittings for joining piping materials have a main body with a substantially equal diameter to that of the piping materials to be joined, an annular expanded portion formed at least at one end portion thereof and enlarged diameter portions on each side of the annular expanded portion. The piping materials are joined by inserting them into the pipe fittings and by pressing the outer enlarged diameter portion along the circumference at an end portion thereof to subject the enlarged diameter portion and the piping materials to plastic deformation. By virtue of recesses formed at the pressed portions, the pipe fittings and the piping materials are firmly fixed together. A tapered portion provided at the end of the pipe fittings effectively increases the slip-off checking force, and also the Joint can be perfectly sealed by the sealing material received in the internal space of the annular expanded portion, having been deformed by the application of pressing. Crevice corrosion can completely be prevented since an adequate clearance is defined between the non-pressed enlarged diameter portion and the piping materials inserted into the pipe fittings.
Abstract:
A method of joining a pair of pipes is disclosed. The method includes forming one of the pipes with an enlarged diameter near one end thereof. A radially-outwardly flared section widens from the enlarged diameter toward the end of the pipe. An elastic gasket and a C-shaped rigid ring are placed in the flared section. A second pipe is then inserted inside the enlarged section of the first pipe. The outer pipe is then inwardly deformed by the action of a pressure member, such as the die, applied to the exterior of the outer pipe in the region of the pipe overlap. The free end of the outer pipe deforms plastically inwardly toward the inserted pipe thereby compressing the gasket into sealing engagement between the two pipes and compressing the C-shaped ring. As the C-shaped ring is compressed, the outer pipe is deformed into the inserted pipe so that the ring is engaged by the inner wall of the outer pipe and is wedged into the outer wall of the inserted pipe.
Abstract:
An optical measuring head which includes a cylindrical portion having a circular cross section, a plurality of light projecting fibers axially disposed in the cylindrical portion through a predetermined distance, a light receiving fiber provided along an axis of the cylindrical portion, and a convex lens formed, at its outer peripheral portion, with a light receiving face for receiving the light from the light projecting fibers and directing the light through the lens so that the light will be incident upon a flat surface of the lens adjacent an object to be measured, through an angle smaller than a critical angle whereby the light will not be reflected by the flat surface, and disposed at a position coaxial with the light receiving fiber for focusing on a forward end face of the light receiving fiber.
Abstract:
Present invention relates to car back-mirror fitted with illumination light. In the conventional cars, forward and backward driving in the night time face no problems with the aid of head lights and rear lamps mounted at the front and rear ends of the car, but sighting of objects approaching from dark right and left side direction of the car or from up or down direction is very difficult due to no side lights. In order to solve the above-mentioned problems, the present invention provides car back-mirror fitted with illumination light which can be rotated in all directions so that dark side directions of the car may be irradiated.
Abstract:
A device for the control of room temperature in existing automobiles is placed in series with the driving circuit of the blower motor of the automobile. The temperature control device includes a bimetal or spiral bimetallic strip capable of setting a working temperature. The bimetal is used for the direct detection of the room temperature of the automobile. An insulating member is attached to a free end of the bimetal. The insulating member carries a first electrical contact, and a mating contact opposes the first contact. Respective lead wires are attached to each contact. A switch lever rotates the bimetal to set a desired temperature. A stopper is provided to hold the contacts together so that, regardless of the ambient temperature, the blower motor remains on, and the user can rely solely on the existing controls.
