Title: Electronic component feeding method
Inventor: KARIGANE KOTARO
IPC: H05K13/02
Filed: 1988-11-12
Abstract: PURPOSE:To enable the transfer of on electronic component to a suction position and to mininaturize an electronic component feeder by a method wherein a cover tape is partially separated from an enclosing recess, and a suction pin is made to descend to an open part of the enclosing recess when it is half open. CONSTITUTION:An electronic component enclosing tape 10 has enclosing recesses 11 at an equal interval, a chip electronic component 12 is enclosed in each recess 11, and the opening of the recess 11 is covered with a cover tape 13. The tape 13 is separated off by a tip 5 of a pressing plate 3. Before the tape 13 is fully separated from the recess 11 or when the recess 11 is half open, a suction pin 41 is made to descend to an opened part of the recess 11. Through the cushioning of a spring, the pin 41 is lightly pressed against the upside of the tape 1, a force pressing the component 12 is kept at a specified value, and the variability of a pressing position of the pin 41 in a vertical direction is absorbed. Moreover, a part of the opening of the recess 11 is covered with a lower end face of the pin 41 to surely prevent the component 12 from jumping out of the recess 11 when the pin 41 is in a descending position. Thus, the movement of the tape 10 and the separation of the tape 13 take place continuously, and the component 12 reaches to a suction position X and taken out from the recess 11. By this setup, a component feeding device can be miniaturized.

Title: Time shift corrector for data collection
Inventor: IKEDA YOSHIAKI
IPC: G04G5/00
Filed: 1995-11-02
Abstract: PROBLEM TO BE SOLVED: To collect measurement signals at an accurately at a constant period by correcting the time shift of a timer on the data collector side with reference to a standard time on the data processor side. SOLUTION: A data processor 30 delivers a measurement start command to a data collector 20. A decision is then made whether the timing is constant and the time shift of a timer in the data collector 20 must be corrected. In the case of a constant timing, a command for correcting the time of timer is delivered to the data collector 20 which is also fed with a standard time from a standard time generating section 31. In the case of high rate sampling, a time interval of about 1min is set and in the case of low rate sampling, a time interval of about 1 hour is set. When a standard time is received by the data collector 20, it is fed from a communication I/O section to the data processor 30 and captured by a timer time correction section 26 where it is set as the time of a timer 24. Consequently, the time of timer 24 is matched with the standard time of data processor 30 and the time shift is corrected.
