Title: Work allotment simulating method for production line
Inventor: SHIBATA KAORU
IPC: G06F19/00
Filed: 1998-11-04
Abstract: PROBLEM TO BE SOLVED: To uniformly distribute a work to working robots arranged in one production line by allotting non-processed spot welding points to be processed within the maximum working time indicated by the designated working time value to one spot welding gun based on the arrangement data and the spot welding data. SOLUTION: Non-processed spot welding points to be processed within the maximum working time indicated by the designated working time value are allotted to one spot welding gun based on the arrangement data and the spot welding data. Since the maximum working time is shortened, non-processed spot welding points which can not be processed within the maximum working time after the shortening of the maximum working time may be generated among the non-processed spot welding points allotted before the shortening with one spot welding gun high in rate of operation. These non-processed spot welding points are re-allotted to other spot welding guns affordable in rate of operation for the maximum working time after the shortening. As a result, the distribution of the spot welding points for the spot welding guns through the whole additional spot welding line are averaged.

IPC: H04N5/44
Filed: 1988-12-12
Abstract: PURPOSE:To prevent a disturbing wave from being caused due to the 3-dimensional distortion of an input changeover switching diode by connecting a distributor to each power terminal of a tuner via a resistance within a video tape recorder and adding a reverse current preventing switching diode to the power terminal of the tuner. CONSTITUTION:A power terminal 8 of a distributor D is connected to a power terminal 9 of a tuner C via a resistance R2 within a video tape recorder B. At the same time, a reverse current preventing switching diode DS3 is added to the terminal 9. In such a constitution, the voltage of 12V is always applied to the terminal 8 even in case the power supply is cut off to the recorder B. Thus the voltage of a prescribed level is applied to the terminal 9. Therefore the RF signal supplied to the tuner C from an antenna input terminal 4 via the distributor D is distorted by an input changeover switching diode DS1 or DS2. As a result, the disturbing wave is never produced.
