Title: Working program storing system or numerical controller
Inventor: SAITOU KIMIO
IPC: G06F9/06
Filed: 1985-08-29
Abstract: PURPOSE:To decrease the transfer frequencies of a working program and also to minimize the waiting time for execution of the next working program, by carrying out the sweeping actions to an auxiliary storage part from a main storage in response to the using frequency of the working program. CONSTITUTION:When a working program is called during a real working mode, the using frequency of the program is calculated. Then it is decided whether a main storage part 3 has the storing room or not for the working program if no working program is stored in the storage part 3. When the storage part 3 has no storing room, the working program that has the minimum using frequency and is not under execution is swept to an auxiliary storage part 4. Then the next working program is stored in the part 3 from the part 4 and registered there. When the execution is through with the stored working program, '1' is subtracted from the using frequency. This can be decrease the transfer frequency of the working program and also minimize the waiting time for execution of the next working program.

IPC: H01S5/00
Filed: 1990-07-18
Abstract: PURPOSE:To prevent a solder from creeping up on an inclined stand and from adhering to the surface of a PD chip by a method wherein a groove is formed in a part where the following are crossed: the side face where the inclined stand, to which a PD submount is attached and which is situated nearly in the center of a stem, is bonded to a block for heat-dissipating use; and the surface of the stem. CONSTITUTION:A groove 8 used to store a solder is formed in a part where the following are crossed: the side face where a block 3 for heat-dissipating use is bonded to an inclined stand, of a stem, to which a PD chip and a PD submount 5 are attached; and the surface of the stem 6. Thereby, when the block 3 for heat-dissipating use is pushed to the inclined stand 7 and is soldered to the stem, the solder flows into the groove 8.
