Title: Processing method for difficult workable material using laser
Inventor: OMORI SHUNJI
IPC: B23K26/00
Filed: 1985-04-23
Abstract: PURPOSE:To process quickly and accurately a difficult workable material such as ceramics by controlling the number of the pulses to be generated of a pulse laser according to a reduction of area. CONSTITUTION:A Z-direction moving head 8 is driven by a driving device 10, an X-direction moving table 5 by a driving device 12 and a Y-direction moving table 6 by a driving device 11. The irradiation position is thereby moved to the prescribed coordinates (X, Y, X) according to the program inputted prelimi narily to a pulse emission control device 13 so that the 1-pulse laser faces one coordinate point. The pulse laser is thus irradiated on one coordinate point on a work 3 through a laser light emitting head 1 from a pulse laser light emitting source 14 to expel the material for one pulse. The above-mentioned operation is continuously and repeatedly executed, by which a groove of a prescribed shape is processed to the work 3. Namely, the groove is formed to the prescribed shape by controlling the number of pulses according to the required reduction of area.

IPC: G06F15/78
Filed: 1983-05-18
Abstract: PURPOSE:To distribute programs with no loss for a microcomputer system where the program and data addresses are controlled independently of each other, by adding a simple gate circuit. CONSTITUTION:The data address is delivered to a bus 16 from a CPU11 and stored to a latch 12, and the address signal is supplied to a data memory 14 and a program memory 15 respectively. If the CS signal is set at a high level, the RD signal is delivered to the memory 14 via an AND gate 17. Then the data is delivered from the memory 14, and the CPU11 reads the data. When the CS signal is set at a low level, the RD signal is delivered to the memory 15 via an AND gate 18. Then a program is delivered from the memory 15 and read by the CPU11. In such a constitution, a data reading instruction is executed while the CS signal is kept at a low level. Thus a program can be read as data and therefore programs can be distributed with high efficiency.
