Title: Optical head driving device
Inventor: EZAWA HIROSHI
IPC: G11B7/085
Filed: 1994-04-01
Abstract: PURPOSE:To keep a sliding characteristic for a long term by means of a supporting mechanism composed of a shaft and a bearing by making the surface hardness of a driven shaft, being easily worn, harder than the surface hardness of a main shaft in an optical head driving device. CONSTITUTION:An optical head driving device is mainly composed of a movable pickup A, a magnetic circuit B for making access and a supporting shaft C (a main shaft 1, a driven shaft 2). The main shaft 1, the driven shaft 2 and the circuit B, B are fixed on a deck base. The surface of the main shaft 1 is coated with solid lubricant having good sliding ability and the material of the driven shaft 2 is stainless steel. The contact of the main shaft 1 with a main bearing 61 is a surface contact and, since the contact of the driven shaft 2 with a driven bearing 62 is line contact, they are easily worn. Stainless steel is used for the base stock of the driven shaft 2 taking into account this fact so that the surface hardness of the driven shaft 2 is made harder than the surface hardness of the main shaft 1. Consequently, the wear resistance is improved and the optical head driving device is manufactured with a low cost since stainless steel is inexpensive.

Title: Optical recording medium
Inventor: HANIYU YUKIO
IPC: G11B7/24015
Filed: 1986-03-25
Abstract: PURPOSE:To obviate the generation of uneven thickness in recording layers in spite of spinner coating and to improve reliability by sticking substrates formed with plural projecting parts spaced from each other in the part near the outside periphery along the outside periphery in such a manner that the projecting parts face each other. CONSTITUTION:This recording medium is formed by sticking the substrate 1 and substrate 2 respectively laminated with the recording layers 3, 4 in such a manner that the recording layers 3, 4 face each other with an inside space 6 in-between. The substrate 1 is a flat plate-shaped substrate which is generally used heretofore and is made into a doughnut shape. On the other hand, the substrate 2 is made into the doughnut shape to meet the shape of the substrate 1 and is so formed that the annular projecting parts 2X project along the inside periphery near the inside periphery of the substrate and that plural pieces of the projecting parts 2Y spaced from each other project along the outside periphery 2a near the outside periphery 2a of the substrate. The outflow of the recording layer material arriving at the periphery of the projecting parts 2Y to the outside from the spaces between the adjacent projecting parts 2Y is thereby made possible in the case of coating the material onto the substrate 2 by a spinner. The generation of the uneven film thickness of the recording layers 4 is thus substantially obviated.

The inner tube 7 provides the outer diameter smaller than the inner diameter of the outer tube 6, and a little longer than the outer tube 6. After inserting the inner tube 7 into the outer tube 6, the inner tube 7 is compressed from the both ends to expand the diameter, and the convex parts of the inner tube 7 are brought into contact with the inner surface of the outer tube 6. According to this constitution, oil which has been flowed into an oil passing space 15 sinuately runs threading along between the concave parts 12, 12a and the inner surface of the outer tube 6, so that it provides good heat transfer rate, less deformation on the inner tube, and no trouble of damage due to the material fatigue.

Abstract: PURPOSE:To provide an air shower device of high efficiency with less power consumption by setting an imaginary rotary column at the central portion within a capsule, forming a lateral flow air curtain in a direction identical with the rotating direction of the imaginary rotary column by cutting the lateral flow air curtain by the column, also forming an airstream turning and advancing from the wall surface of other horizontal wall, and setting the upright position of a person to be processed at the central portion of the imaginary rotary column. CONSTITUTION:An air flow fed through a large number of holes 43 formed in a vertical cylinder 42 is blown off from a blow-off port 41. An imaginary rotary column 6 is set at the central portion within a capsule 21, and a lateral flow air curtain 44 is cut by the imaginary rotary column 6. At a cutting point 61, the lateral flow curtain 44 is formed in a direction which is identical with the rotating direction of the imaginary rotary column 6, thus directing the lateral flow air curtain toward an intake port 52. A turning advancing air stream 7 forms a whirlwind, thus is directed toward the intake port 52. The turning air flow speed of the air stream is extremely high and the dedusting processing is carried out extremely rapidly and positively. Thus, when the airstream reaches the intake port 52 of a blasting duct 51 and is sucked up and shifted, it passes through a dust collector and is dedusted and purified, and circulated to the blow-off port 41.
