Title: Die casting machine and casting method by die casting
Inventor: KAWANO KATSUUMI
IPC: B22D17/20
Filed: 1993-08-31
Abstract: PURPOSE:To stabilize the supply of molten metal by supplying powdery release agent into a cavity after reducing the pressure in the cavity and successively, supplying the molten metal with an electromagnetic pump while degassing back pressure gas in the cavity. CONSTITUTION:The pressure in the cavity 13 is reduced to a prescribed pressure by working a vacuum pump 62. Successively, this reduced pressure is detected and the powdery release agent 30 is supplied into the cavity 13 from a sleeve 21 by working a release agent supplying device 3 through a control unit 8 based on the signal. After supplying the release agent 30, a solenoid valve 71 for reducing the pressure is closed and a solenoid valve 72 for opening the air is opened to degass the back pressure gas. Thereafter, a plunger tip 22 is retreated and an electromagnetic pump 4 is worked by putting on a limit switch 82 to supply the molten metal in a holding furnace 5 into the sleeve 21. Successively, the molten metal is poured into the cavity 13 to execute the casting by advancing the plunger tip 22 to a prescribed position, and a high quality cast product is cast.

Filed: 1994-09-09
Abstract: PURPOSE:To facilitate reproduction by recognizing positioning of a picture part to an entire picture, a head address, and an end address and storing picture data stored through division continuously in a memory altogether. CONSTITUTION:A CPU 107 sequentially implements reading of a route directory, retrieval of FATs, reading of a header and setting processing of a start/end address. The CPU 107 gives a CNT 1 to a frame memory control section 105 and a card control section 110 after address setting, and a controller 105 gives a CNT 2 signal in response to the CNT 1 signal to the card control section 110.

Title: System for controlling synthesizer
Inventor: TAKEI NORIMICHI
IPC: H03L7/08
Filed: 1998-07-30
Abstract: PROBLEM TO BE SOLVED: To suppress digital noise generated from a synthesizer by means of invalid data which is not latched by a frequency divider and becomes invalid when a strobe signal is not transmitted and a clock signal during that time in the programmable synthesizer of a three line control system. SOLUTION: A clock signal 1, a data signal 2 and a strobe signal 3 are generated of necessary '1' and '0' signals by a micro computer.
