Title: Drawing method of glass fiber strands
Inventor: MATSUOKA OSAMU
IPC: B65H49/18
Filed: 1978-06-23
Abstract: PURPOSE: To rewind glass fiber strands drawn out from tubes with an adequate tensile force, by introducing them through elastic guides to the ensuring processes such as twisting.

Title: Apparatus for tracking moving body by utilizing laser beam
Inventor: TANAKA HIDEHIKO
IPC: G01S17/66
Filed: 1984-04-15
Abstract: PURPOSE:To enable highly accurate tracking, by providing a tracking control apparatus capable of changing the tracking speed of laser beam to a fixed station side. CONSTITUTION:Terminals T1, T2 are set to a H-level and terminals T3, T4 to a L-level. Therefore, AND gates A1, A2, A4 are under a L-level state. A memory operation apparatus 14 detects the angle of a reflection mirror 3 on the basis of the output of a counter 13 and calculates the optimum angle speed of the mirror 3 on the basis of the detected angle. The apparatus 14 calculates a frequency dividing value inversely proportional to the angle speed and imparts the same to a frequency dividing value setting register 16. The resister 16 imparts this set valve to a presettable counter (PDC)17 which in turn receives a clock pulse from a pulse generator 18 to perform decrement count from the set value. When the count value of PDC17 comes zero, a bolo signal is outputted from PDC17 and the output thereof is imparted to gates A1-A4 through FF19. By this method, the driving times of pulse motor drives 20, 21 are made variable and the mirror 3 is driven corresponding to the distance of a moving body.
