Title: Device and method for adjusting tracking balance
Inventor: INOUE AKIRA
IPC: G11B7/095
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To reduce time required for adjusting tracking balance. SOLUTION: The number of cycles of the waveform of a tracking error signal that is detected when an optical disk 1 is rotated is counted for a fixed amount of time by a waveform-counting circuit 131. It is judged whether the number of cycles has reached a specific number or not by a judging circuit 133. Then, if it is judged that the number of cycles has reached the specific number, the center voltage of the tracking error signal is taken out by an LPF 6 as a bias value. Otherwise, a sled 2 is moved by a motor 11 and a center voltage is taken out by the LPF 6 as a bias value for the tracking error signal being detected by the move of the optical pick-up 1.  Also, when the optical pick-up 1 moves, the traveling direction of the optical pick-up 1 is determined by a limit switch 12 for detecting the innermost periphery position of an optical disk 3, thus performing control so that the optical pick-up 1 can be returned to its original position based on traveling time.

Filed: 1991-02-26
Abstract: PURPOSE:To obtain the waveguide type optical switch having no dependency on polarized light by constituting this switch in such a manner that the length of 3 times the complete coupling length the propagating light handled by the optical switch to ordinary light and the complete coupling length to the extraordinary light are equal to the length of a coupling part. CONSTITUTION:The complete coupling length Lo to the ordinary light is always smaller than the complete coupling Le to the extraordinary light in the optical waveguide formed by diffusing a metallic thin film of an ordinary film thickness. The waveguide parameters, for example, inter-waveguide intervals, film thickness, etc., are so selected that the length L of the coupling part of the switch satisfies L=3Lo=Le The electrooptical constant of the extraordinary light is about 3 times the electrooptical constant of the ordinary light with the optical waveguide of the optical switch constituted in such a manner. Then, the voltage to be impressed to the coupling part of the optical switch is about 3 times the voltage necessary for putting the extraordinary light into a bar state in order to put the ordinary light into the bar state. The bar state is substantially obtd. with the extraordinary light as well if the electric field is impressed to the optical switch on the bases of the bar state of the ordinary light.

Abstract: PURPOSE:To simply carry out the outer peipheral sewing of an air bag through final sewing without hemming by using a sewing thread whose thickness, rupture ductility and strength are severally specified for the sewing of an outer peripheral, edge in the vehicle air bag whose outer peripheral edges of cloths on both the sides of an inflater and of a crewman are sewed together. CONSTITUTION:A vehicle air bag is composed of an inflater side cloth 1 having an opening part 3 for attaching the inflater and a vent hole 4 and a crewman side cloth 2 having an external form being the same as the inflater side cloth 1. After the outer peripheral edges of cloths 1, 2 on both sides are sewed together, the cloths are turned to their surface sides for making the air bag. In this case, in sewing the outer peripheral edges of the cloths 1, 2, a specified sewing thread is used. Namely, the sewing thread is specified so as to have thickness being more than 315 d, 40 to 60% of rupture ductility and strength being more than 5g/d. Thus the elongation of the sewing thread itself is utilized to relieve stress acting on a sewed part at the time of developing the air bag. The outer peripheral sewing of the air bag can therefore be simply carried out by only final sewing without hemming.
