Title: Magnetic disk
Inventor: KINOSHITA KATSUYOSHI
IPC: G11B23/00
Filed: 1990-01-22
Abstract: PURPOSE:To improve the workability of assembly by integrally constituting a pressing means which presses the shaft of a magnetic disk driving device to a prescribed side and providing this pressing means with a flexion preventing means. CONSTITUTION:When a shaft 18 of the magnetic disk driving device is inserted to a center hole 17, the shaft 18 is pressed to the side of a core reference face 19 by the force of a spring part 11, and recording and reproducing are satisfactorily performed by the recording and reproducing head of the magnetic disk driving device. Though the spring part 11 made of plastics is apt to be permanently deformed by heat because a magnetic disk 3a is placed at a relatively high temperature during this recording/reproducing operation, the spring part 11 is provided with a projecting part 12 to hardly plastically deform th spring part 11 itself, and the rear end part of the projecting part 12 of the spring part 11 is detained by a detaining part 16 of a lower core 6 to more hardly plastically deform the spring part 11.

Title: Method and equipment for polishing flat surface of hard and brittle plate
Inventor: SUZUKI ISAO
IPC: B24B37/04
Filed: 1982-01-25
Abstract: PURPOSE:To prevent the production of the Twyman effect, by using vacuum suction to secure a hard and brittle plate on a mounting surface to polish one side of the plate and by finish-polishing the plate while the plate on which the Twyman effect is produced by the former polishing is vacuum-sucked on a suction surface of high flatness so that the Twyman effect is corrected. CONSTITUTION:A glass plate 10 is vacuum-sucked on a suction surface 42 of 1mu or less in roughness. One side of the plate 10 is polished by a secured polishing material 40. The plate 10 whose finish-polished side is made concave at 2 due to the Twyman effect is then vacuum-sucked to polish the other side. Polishing for a surface of high flatness is thus enabled.

Title: Method for evaluating semiconductor wafer
Inventor: MATSUSHITA MITSUYOSHI
IPC: G01N23/20
Filed: 1992-01-27
Abstract: PURPOSE:To evaluate continuity of extrinsic gettering(EG) treatment effect regardless of presence or absence of heat treatment by obtaining an amount of strain on a wafer surface. according to angle change of a rocking curve on the semiconductor wafer. CONSTITUTION:When an X-ray beam which is turned into monochromatic color with two crystals or three crystals is shed onto a semiconductor wafer surface, an angle spread of a same bending point of Bragg reflection under no strain is normally and approximately less than 10 seconds. On the other hand, the angle spread of diffraction point from the surface where a strain is given by sandblasting is approximately 30 seconds or longer, thus enabling the difference between both to be detected as an amount of strain. Therefore, since a process for realizing an oxidation generation lamination defect can be eliminated, the EG treatment effect can be directly evaluated. Also, after the same wafer is subjected to heat treatment successively, the change in the amount of strain can be evaluated for enabling continuity of the EG effect to be evaluated.

Title: Holding method for pellicle film
Inventor: NAITO KENJI
IPC: G03F1/64
Filed: 1986-01-24
Abstract: PURPOSE:To eliminate the generation of a temp. difference and a pressure difference between an inside part and outside field by forming a pellicle holder of a material having air permeable small holes. CONSTITUTION:The construction of a pellicle film 12 and the pellicle holder 21 are exactly the same as in the conventional practice. The pellicle holder 21 is made of a material having mechanical strength and air-permeable small pores 23, for example, sintered nickel. Dust 15 is hampered by the Ni particles 22 and cannot pass the pellicle holder 21 but air can pass the holes 23 and therefore the air flows between the inside and the outside field. The increase of the internal pressure in excess of the pressure of the outside field by following up the pressure of the outside world or the decrease thereof below said pressure is thus prevented. The generation of the pressure difference between the inside and the outside field in the use, preservation and transportation of a mask is thereby prevented and the exposing with high accuracy is executed.
