Patent JP-H10322949-A (JP)
Title: Spindle motor
Inventor: NARA EIJI
IPC: H02K21/22
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To reduce the manufacturing cost by simplifying the slip stoppage structure of a rotor, and reducing the number of parts and man-hours in assembly. SOLUTION: A slip stoppage structure is formed, which prevents the upward slip out of a rotor 103, with its slip stoppage part 130 being bent and transformed and getting over a locking projection 120 and being regulated with the locking projection, when inserting a rotary shaft 120 where the rotor 103 is fixed into an oil-containing bearing 108, by projecting the locking projection 120 outwards in the radial direction at the upper part of a bearing stand 107 and projecting the slip stoppage part 130 at the reverse bottomed part 103a of the rotor 103.  Even if there is dispersion in the clearance in the radial direction between a rotary shaft 102 and the oil-containing bearing 108, this can be arranged so that the dynamic property of the rotor 103 does not deteriorate, by suppressing the axial deviation of the rotor in a high-speed rotation range, so that the slip stop process using a slip stoppage metal fitting is needless, and the manufacture cost can be reduced, by curtailing the number of parts and the man-hours in assembly.

Title: Magnetic recording medium and its production
Inventor: OSAWA HIROSHI
IPC: G11B5/738
Filed: 1997-05-19
Abstract: PROBLEM TO BE SOLVED: To enhance the CSS of a magnetic recording medium by providing the congested part of protrusions in a magnetic recording medium in which protrusions are formed on a substrate, thereby reducing the maximum load applied to each protrusion without increasing a friction factor. SOLUTION: At the congested part of protrusions, 2-10 pieces of protrusions are consecutively formed in a circumferential direction, and the interval D1 between outer end parts of the protrusions and the interval D2 between congested parts are respective defined as 0.1-10 μm and 10-100 μm. When the number of the protrusions is 11 and the interval D2 is 10 μm, a protrusion density is too high to cause the possibility that a head is attracted to the surface of a disk, and when the interval D1 is 0.1 μm, the mutual interference between protrusions each other is caused, and further when the interval D1 is >=10 μm, the head load is not sufficiently dispersed. Furthermore, when the interval D2 is >=100 μm, the interval between protrusions is too wide to affect the flying stability of the head.  Then, a protrusion itself is regulated to 1-10 μm in diameter and to 1-30 μm in height to avoid the influence of a weak glide noise being the CSS characteristic.

Title: Semiconductor device
Inventor: NISHINO SEIICHI
IPC: H01L21/48
Filed: 1981-08-18
Abstract: PURPOSE:To eliminate the production of rust and to improve the uniform electrodeposition of a semiconductor device of seam weld type hermetically sealed by a metal cap by forming a plated layer on the surface except the center on  the back surface of the cap. CONSTITUTION:A simple discrimination of front or back surface via a part feeder, parts are then aligned and the projections are mounted via an adhesive 9. In case of an electroless plating, the projection 10 does not produce a loss of plating precipitation when formed of a plastic block, and when an adhesive is coated on the plastic block side, the block can be relatively readily mounted on the aligned caps which are not yet plated, thereby efficiently performing the work before plating. Since the metal cap is sintered in hydrogen at 600-800 deg.C to remove the strains of the plated film and kovar and to raise the plating adherence in the final step, it does not remain as a foreign material in the product even if small amount of adhesive remains.

CONSTITUTION:Power of the reflected wave of microwave emitted from an etching chamber 3 is detected by a power minitor 2. A signal is sent to a parsonal computer 6 and power of effective microwave is calculated. A microwave power source 7 is controlled on the basis thereof and power of effective microwave is always held constant. Further the computer 6 predicts the thickness of a film built-up on the inner wall of a bell jar 1 from the data of power of the reflected wave. A gaseous oxygen supply source 8 is controlled by this film thickness so that the concn. of effective gaseous oxygen in the chamber 3 is always held constant. On the other hand, density of plasma is detected by a detection terminal 4 and a signal is sent to the computer 6. A state of plasma is always held constant by controlling the power source 9 of a magnetic field coil and the power source 7 of microwave. Thereby the etching rate is not changed with the lapse of time and accordingly the yield is enhanced.

Filed: 1978-10-19
Abstract: PURPOSE:To prevent an electrical current capacity from deceasing, by soldering or brazing a relatively-thin superconductive wire of small bending stress, on a normally conductive wire almost wound by bending. CONSTITUTION:A copper wire 5 is wound by bending.
