Title: Metallic casting mold
Inventor: ARAI KATSUO
IPC: B22C9/00
Filed: 1980-06-04
Abstract: PURPOSE:To obtain a casting hardware having a good quality with a simple construction, by providing a metallic mold built-in with heat pipes of which each both ends are positioned respectively near a thin-walled part and a thick-walled part of a casting mold to cool all over a molten metal in a cavity almost uniformly. CONSTITUTION:When a molten metal 3 is poured into a cavity 2 surrounded by metallic molds 1a, 1b, heat of a thick-walled part 4, as the metal 3 is cooled, is transmitted in the arrow direction to a thin-walled part 5 through heat pipes 6, and the temp. difference both parts 4, 5 becomes smaller. As a result, the molten metal 3 in the cavity 2 is cooled all over itself almost uniformly, so that occurrence of several kinds of defects, due to the unevenness of the cooling velocity, such as hardenings, cracks in the thin-walled part, shrinkage holes, porosities in the thick-walled part can be prevented. Further, the pipe 6 filled and sealed with a working fluid 7 receives a heat at its end to raise a temp. of the fluid or to evaporate it, release the heat at its other end to condense the evaporated fluid.

Filed: 1986-03-31
Abstract: PURPOSE:To expand a usable range and improve a degree of usability, by performing width shifting in an intermediate tray automatically in making it correspond to width of the paper set in a manual paper feeder. CONSTITUTION:When paper P is fed out of a paper feeding cassette, its width i determined in conformity with the type of the paper feeding cassette. At a point that the paper P is led into an intermediate tray, a solenoid 66 is energized with a continuous rating current so that slide members 64 are in a state of being separated from each other against a tension spring 66, whereby installation of the paper P is performable without any resistance, that is, without entailing rumples, folds, etc. And, after installation of the paper P, since current- energization to the solenoid 66 is cut off, these slide members 64 come nearer to each other as far as the distance allowed by a long aperture hole 62 by dint of energizing force of the tension spring 68, and width shifting for the paper P is carried out, whereby the center of the paper P is accorded with the reference position.
