Title: Structure and method for supporting guide shaft
Inventor: NAKAYAMA TATSUYUKI
IPC: F16C29/02
Filed: 1998-04-16
Abstract: PROBLEM TO BE SOLVED: To permit the support with relatively excellent positional accuracy without necessity of a special jig and a process by providing a support member with a recessed part corresponding to a curved surface of a guide shaft, and fitting the guide shaft in this recessed part for connection. SOLUTION: A round bar is used for a reference guide shaft 17 for guiding an optical pickup freely to be moved in the radial direction of a CD-ROM. A reference guide shaft support part 33 is formed with a recessed part 36 having an arc-like cross section, and a front end 17a of the reference guide shaft 17 is fitted in the recessed part 36. In the condition that the reference guide shaft 17 is fitted in the recessed part 36, the reference guide shaft 17 is fixed to the reference guide shaft support part 33 by laser welding or the like. At this stage, curvature of the recessed part 36 is formed as nearly same as the curvature of the outer peripheral surface of the reference guide shaft 17 so that the reference guide shaft 17 is not moved in the recessed part 36 when the reference guide shaft 17 is fitted in the recessed part 36.  With this structure, the reference guide shaft 17 can be temporarily fixed to the reference guide shaft support part 33 without performing a special working to the reference guide shaft 17.

Title: Positioning servo control device
Inventor: ABE RIICHI
IPC: G05D3/12
Filed: 1979-08-21
Abstract: PURPOSE: To ignore the disturbance due to the delay time of transmission, by sample-holding the output of the position deviation counter by the sample pulse having a much longer period than the delay time of transmission of the photocoupler or the D/A converter.  
     CONSTITUTION: The position deviation counter 11 obtaines the deviation signal by counting the difference between the command pulse and the feedback pulse delivered from the position detector 17, and then applies this deviation signal to sample holding circuit 12. The circuit 12 carries out the sample holding with the sample pulse having a much longer period than the delay time of transmission of the photocoupler 13 or the D/A converter 14. The position deviation which is sample- held once at the circuit 12 is applied to the converter 14 via coupler 13. The converter 14 converts the applied position deviation into the analog signal and then applies this analog signal to the actuator 16. Thus the actuator 16 is operated so that the position deviation may be 0.

The films 2.4 are removed for the formation of a vertical trench in a site planned for isolation by oxidation. A process follows wherein heat treatment is accomplished at a temperature where the polyimide film 4 experiences a fluid-like deformation. The result is a polyimide film 4' providing eaves extending over the trench from the circumference of the region to be oxidized. A process follows wherein ions 6 similar in polarity to the semiconductor substrate 1 are implanted into the region planned for oxidation. The polyimide film 4' is removed and then an insulating oxide region 8 is formed in a high-temperature steam oxidation process. This design simplifies the formation of a dielectric isolation layer using a semiconductor substrate.
