Title: Magnetic head arm structure
Inventor: OKADA MITSUHIRO
IPC: G11B21/02
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To obtain a magnetic head arm structure which is resistant to vibrations and impacts by making the center of gravity of a magnetic head arm coincident with the center of rotation of the arm. SOLUTION: A shaft 15 is provided at or near the center of gravity G of a magnetic head arm 10. When the shaft 15 is made coincident with the center of gravity G of the arm 10 in such a way, no rotational force acts on the arm 10 by reaction and the positional deviation of a magnetic head 11 from a track due to vibrations or impacts can be prevented even when the vibrations or impacts are applied to the arm 10 in the moving direction. In addition, the size and weight of the driving motor of the arm 10 can be reduced, because the motor does not require any strong braking force. It is preferable to constitute the arm 10 so that its mass can be increased near the center of rotation and reduced near the head 11.

Title: Semiconductor laser bar and manufacture thereof
Inventor: KANEIWA SHINJI
IPC: H01S5/00
Filed: 1993-08-06
Abstract: PURPOSE:To prevent a semiconductor laser bar from being broken when the laser bar is handled by a pair of tweezers or the like by a method wherein the thickness of semiconductor wafers is reduced by etching and the end on at least one side of the ends of each semiconductor wafer is formed thicker than the part other than the end by spin etching. CONSTITUTION:Wafers 1a, 1b, 1c and 1d are adhered on a disc 6 using wax and while an etching liquid is jetted on the wafers, the wafers 1a, 1b, 1c and 1d are rotated at high speed together with the disc 6. After being etched to a prescribed thickness, the wafers 1a, 1b, 1c and 1d are detached from the disc 6. Wafer end parts, whose thickness is formed thick in this spin etching process, form two sides 7 and 7 on the sides, which are apart from the center O of rotation of the disc 6, of each wafer. The wafer thickness at a region of a width W from the end of each wafer subsequent to the etching is formed thick by the thickness of DELTAT compared to the thickness T of the part other than the region. Thereby, a semiconductor laser bar can be prevented from being broken when it is handled by a pair of sweezers or the like.

Title: Gas spring device
Inventor: KAYANO KOICHI
IPC: F16F9/00
Filed: 1988-08-08
Abstract: PURPOSE:To minimize the fitting space by disposing separate change-over valves in a bottom member or in a bearing member and constructing such that an annular chamber is communicated with a piston side house or a rod side house when these separate change-over valves are released. CONSTITUTION:When both change-over valves 6, 9 are in the closed state, stretching force and shrinkage force are balanced so that a gas spring device is in the stop state. When the valve 9 is released, a piston side chamber A and a rod side chamber B are communicated, and the pressure difference is generated between the side chamber A, B so that the gas spring is stretched. In this case, when the large outer force such as to push a rod body 2 into a cylinder body 1 acts, the gas spring shrinks. When the valve 6 is released even when the valve 9 is closed, an annular chamber C is selectively communicated with the side chamber A or the side chamber B so as to enable the stretch and shrinkage of the gas spring. As the respective valves 6, 9 are independently disposed, they can be operated separately.
