Title: Precision casting method using ice pattern
Inventor: HIRATA TOYOJI
IPC: B22C9/04
Filed: 2000-03-02
Abstract: PROBLEM TO BE SOLVED: To provide a method for manufacturing precision casting parts only by using the ordinary water and an inexpensive mold. SOLUTION: The water is poured into a synthetic resin-made mold, in which the reverse outlines corresponding to the outlines of the parts are recessedly arranged as plural cavities, and this water in the mold is frozen in a freezing chamber to form ice patterns. The ice patterns are taken out by disassembling the mold and these are dipped into a slurry having suspended fine powder of refractory, and after coating the slurry film on the surface of the ice pattern, these are taken out from a vessel and dried. A refractory-made mold formed by repeating such works of prescribed times, is carried out from the freezing chamber and the ice patterns in the mold are melted and eliminated when these are left in a room temperature. After burning the mold formed as the cavity state in a burning furnace, molten metal is poured into the cavity.  After cooling, cast parts are cut off from a sprue and runners and carried out to a prescribed finish process to manufacture a necessary product.

IPC: A63F7/02
Filed: 2000-04-06
Abstract: PROBLEM TO BE SOLVED: To eliminate hardware-based competition between an NMI interrupt and a user's reset interrupt in the preserving of memory with a battery backup. SOLUTION: After processing at a step S18, whether or not an NMI flag is NO is determined (step S19) and when YES is given, a power failure signal is determined to be inputted to forbid access to a RAM (step S23) so that the solenoid output is turned OFF (step S24) to stand by the program on a loop. When NO at the step S19, none of the power failure signal is determined to be inputted and a residual processing, namely, an initial value random number updating processing (step S20) and a random number updating processing for pattern (step S21) is executed to judge whether or not an INT flag is ON, that is, whether or not the time expires (passes 2.731 lms) (step S22). When NO, return is made back to the step S20 to continue the residual processing, or when YES, the residual processing is aborted to shift the processing to a step S10.
