IPC: G11B7/09
Filed: 1991-08-15
Abstract: PURPOSE:To stabilize servo performance by providing an acrylate resin material for suppressing vibrations between a coil for focusing control and coil for tracking control and an objective lens holder. CONSTITUTION:This objective lens actuator is constituted by providing the acrylate resin material 35 between the coil 33 for focusing control and the objective lens holder 28 and curing only the part near the surface of this acrylate resin material 35 to hold the resin material internally uncured. The attenuation rate of a moving part constituted of the objective lens 30, the objective lens holder 28, the acrylate resin material 35, the coil 33 for focusing control, etc., is, thereupon, increased. A resonance peak value can be decreased in this way and the light beam spot to be condensed by the objective lens 30 can be made to stably follow up the surface waving and eccentricity of an information recording medium.

Title: Controller for inverter
Inventor: KAWABATA MASAHIKO
IPC: H02P23/16
Filed: 1985-09-19
Abstract: PURPOSE:To reduce the quantity of speed variation on restart, and to shorten a reset time to regain a speed just before the generation of instantaneous service interruption by detecting the speed of a motor under a free-run state after the generation of instantaneous service interruption. CONSTITUTION:When instantaneous service interruption is generated, a motor 2 is brought to a free-run state while a command is transmitted over a changeover circuit 9, and a speed reference is changed over to the holding circuit 10 side from the external speed reference 8 side. The speed V of the motor 2 is detected at all times during that time because a tachometer generator 3 takes a permanent magnet type, and fed back to a speed control circuit 6. The holding circuit 10 holds voltage applied from a voltage divider 11 at a moment when instantaneous service interruption is returned, turns the speed of the motor into the speed of a restart speed reference R'ef as regenerative- mode operation, and changes over the changeover circuit 9 into the external speed reference Ref.

IPC: E04G3/00
Filed: 1998-07-06
Abstract: PROBLEM TO BE SOLVED: To provide a working scaffold inside a cylindrical structure capable of contributing to reduction of construction period. SOLUTION: A rail member 11 is laid in the form of a ring along the interior wall of the inner lower bottom of a cylindrical structure 1 and a wheel 12 mounted on the lower bottom of a scaffold structure 13 erected in a vertical position can move along the rail member 11.

Title: Magnetic recording medium
Inventor: SHINOHARA KOICHI
IPC: G11B5/72
Filed: 1987-08-20
Abstract: PURPOSE:To obtain both good C/N and durability by providing a lubricating agent layer contg. a coupling agent into which a magnetic diluting element M for a perpendicularly magnetized Co-M layer is incorporated on the perpendicularly magnetized film. CONSTITUTION:The lubricating agent layer 3 contg. the coupling agent into which the magnetic diluting element M for the perpendicularly magnetized Co-M film is incorporated is provided on the perpendicularly magnetized Co-M film 2. Since the lubricating agent protects the magnetic recording layer 2 by reacting strongly therewith, the durability under high-speed sliding movement with a magnetic head is improved. The durability is assured even if the excessive lubricating agent is not disposed and, therefore spacing losses are decreased to a negligible level. The good state of C/N at short wavelengths is thus maintained. The high-density magnetic recording by using the perpendicularly magnetized film is thereby assured at the good C/N in the state of assuring the durability.

Title: Color picture tube
Inventor: OCHIAI YONEMICHI
IPC: H01J31/20
Filed: 1996-08-06
Abstract: PROBLEM TO BE SOLVED: To reduce landing drift by making the spring pressure at a first bent portion greater than that at a second bent portion of an elastic support member. SOLUTION: An elastic support member 17 is a plate spring of a generally constant width, a first bent portion P1 on the mask frame side, and a second bent portion P2 on the panel pin side. A triangular opening 31, with its width gradually widening from the bent portion P1 toward the bent portion P2, is formed in a slope portion 17c between the bent portions P1 and P2. Therefore, spring pressure gradually decreases from the bent portion P1 toward the bent portion P2. By the way, the landing drift in the prior art structure in which no opening 31 is formed in the elastic support member is about 20 micrometers. In contrast, with the provision of the opening 31, in the case of A=19mm and B+C=10mm for example, the landing drift is improved to 5 micrometers.
