Filed: 1990-05-07
Abstract: PURPOSE:To produce a cast billet having excellent surface characteristic by giving periodical variation to current conducted to an electromagnetic coil in a continuous casting apparatus for casting while giving electromagnetic force to molten steel in a mold. CONSTITUTION:In the continuous casting equipment for casting while giving the electromagnetic force to the molten steel by setting the electromagnetic coil L surrounding the mold at outside of the mold filled with the molten steel, the current conducted to the electromagnetic coil L is periodically varied at between a first level for needing to give the prescribed pinch force to the molten steel and a second level for needing to temporarily maintain deformed condition at peripheral part of the molten steel developed with the pinch force. By this method, boiling-out of the molten steel on the surface is prevented and the molten steel surface characteristic is stabilized and the quality of cast billet can be improved.

Title: Image reader
Inventor: KUSUMOTO KEIJI
IPC: G03G21/00
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To provide an image reader where temperature of a light source lamp is always adjustable without reducing the service-life of the light source lamp while avoiding interruption of temperature adjustment of the light source lamp on the occurrence of a heater failure. SOLUTION: When a heater 33 is not faulty, a CPU 102 uses the heater 33 to adjust temperature of a fluorescent light 12, and should the heater 33 be faulty, the CPU 102 controls the fluorescent light 12 to adjust the temperature of the fluorescent light 12. Thus, it is not required to adjust the temperature of the fluorescent light 12 through lighting of the fluorescent light 12 itself normally, then the service-life of the fluorescent light 12 is not reduced and should the heater be faulty, the temperature of the fluorescent light 12 is adjusted by the fluorescent light 12 itself, then interruption of the temperature adjustment of the fluorescent light 12 is avoided.

Title: Thermal transfer printer and manufacture of pinch roller used to the printer
Inventor: KASUGAYA TOMOAKI
IPC: B41J13/076
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To prevent plastic deformation from being caused on the surface of a picture-receiving paper by a pressing force of a pinch roller by forming the pinch roller so that roller end faces reduce the pressing force applied to the picture-receiving paper. SOLUTION: When a pinch roller 1 is formed around a pinch roller shaft 12 in molding, the molding is performed by fixing rings corresponding to the assumed shapes to shaping portions, and, after finishing the cutting of an outer diameter of the pinch roller, the rings are removed. By this method, both ends of the pinch roller 1 are formed into a shape having different widths at the outer peripheral part and at the inner peripheral part thereof.  In the case of printing operation, when the pinch roller 1 is pressed against a picture-receiving paper, the pressing force is continuously reduced toward the direction of the end faces of the pinch roller 1 because the pinch roller 1 itself is deformed in the direction of an air layer in the pinch roller 1, and the end portions of the pinch roller 1 are almost free from the pressing force, so that no flaw is caused on the picture-receiving paper by the ends of the pinch roller 1.

Filed: 1992-04-10
Abstract: PURPOSE:To double the oil feeding rate of a fuel injection pump with respect to the same cam profile, with a simple structure, by making the number of rotations of a face cam-equal to that of an engine, and, at the same time, making the number of convexity of the face cam 1/2 of the number of cylinders of the engine. CONSTITUTION:When a drive shaft 4 is rotated with the same number of rotations as that of an engine, both a face cam 22 and a plunger 21 are also rotated with the same number of rotations. When a convexity 24 axially moves the plunger 21 through rotation of the face cam 22, a fuel is caused to pass through a distribution groove 13, an outlet port 12, a two-way control valve 28, and a fuel distribution passage 14-1 to be force fed to a fuel injection nozzle for a first air cylinder, thus being injected. On the other hand, when the face cam 22 is rotated through an angle of 180 deg., another convexity portion 26 causes the plunger 21 to be axially moved whereupon the fuel is force fed to the fuel injection nozzle for a third air cylinder. By making the number of the convexities 24, 26 half the number of the air cylinders, the speed of the face cam 22 and the oil-feeding rate of the fuel injection pump is doubled as compared with those in the prior art.

The inside of the cylinder 2 is kept at non-oxidizing atmosphere and molecular weight can be prevented from deteriorating as nitrogen gas is supplied within the hopper 4. In addition to the above, as once the ultra-high-molecular-weight polyethylene is melted crosslinking is started immediately after the melting, if the title method is so constituted that the foregoing polyethylene is poured into the cavity 5 immediately through the nozzle part pouring can be done while it is fluid.
