摘要:
In a spindle motor utilizing dynamic-pressure bearings having a full-fill structure, a bearing configuration that balances and sustains at or above atmospheric pressure the internal pressure of the bearing oil. Thrust and radial bearing sections are configured within oil-filled bearing clearances in between the rotor, the shaft, and a shaft-encompassing hollow bearing member. A communicating passage one end of which opens on, radially inwardly along, the thrust bearing section is formed in the bearing member. Either axial ends of the bearing clearance in between the bearing member and shaft communicate through the passage. The communicating passage enables the oil to redistribute itself within the bearing clearances. Pressure difference between the axial upper and lower ends of the oil retained in between the bearing member and the shaft is compensated through the communicating passage, preventing incidents of negative pressure within the oil and of over-lift on the rotor. And an annular protruding portion is formed on at least one of the end face of the bearing member and the flat face of the rotor at radially inward portion of the thrust bearing section.

A reinforcement ring is insert-molded as an insert body on a reel hub of a reel around which recording tape is wound. The reinforcement ring includes a metal ring at least whose inner peripheral surface is covered by a resin layer. The clearance between the reinforcement ring and a mold during reel molding can be reduced, and the amount of eccentricity of the insert body with respect to the reel hub can be reduced.

An image display apparatus includes: a display displaying an image with a predetermined number of pixels; an image holding unit holding an original image composed of a number of pixels larger than a number of pixels that is displayable on the display; and an object judgment unit judging whether or not an object is included in the original image held in the image holding unit, and generating object information related to the object in a case where the object is included in the original image. The image display apparatus also includes a display image generation unit extracting at least a part of an object area from the original image based on the original image specified by the user as well as on the object information corresponding to the original image, and generating a display image composed of a number of pixels corresponding to the number of pixels that is displayable on the display.
摘要:
A method of producing a laminate body having a thin metal layer on a substrate including processes (1) to (4) as follows: (1) preparing the substrate; (2) blowing a flame in which a silicon containing compound is introduced; (3) forming an undercoating layer by coating with a lacquer or a primer; and (4) forming a thin metal layer by reducing a metal ion. In addition, process (5), in which a topcoating layer is formed on the metal layer is preferably included in the present invention. The present invention makes it possible to coat various substrates with the metal layer (silver mirror). Practically all kinds of substrate may be used as a substrate to be coated.

A still image reproducing apparatus in which a user selects one piece of information, and production of still images and music associated with the mood in time of the production is provided. A still image reproducing apparatus 100 comprises: an image feature extraction unit 102 which analyzes image data, so as to extract feature; a music feature extraction unit 106 which extracts a music feature quantity from music data; and a mapping process unit 109 which uses each feature, so as to respectively map image data and music data on each sensitivity map using two axes. The user selects, from the sensitivity map, via a menu input unit 111, a quadrant for music or images desired in a slide show. Thus, the slide show associated with the mood is automatically produced in a slide show generation unit 110.

A reel has: a hub that has a cylindrical tube portion, an extending portion that extends from an inner peripheral edge of a lower end portion of the cylindrical tube portion toward a radial direction inner side, and an abutting portion provided at the extending portion; an upper flange; a lower flange; and a floor wall that is provided integrally at the radial direction inner side of the lower flange, and that has a position restricting portion that restricts a radial direction position of the abutting portion from the radial direction inner side. A region of the floor wall which is further toward the radial direction outer side than the position restricting portion is welded to the extending portion.

This display includes a light source portion, a first heat radiation member for radiating heat generated by the light source portion, a rear housing covering the first heat radiation member in a state in contact with the first heat radiation member, and a cover member covering a rear surface of the rear housing so that the rear surface of the rear housing is partially exposed outward. The first heat radiation member is arranged on a region corresponding to a region of the rear housing exposed outward from the cover member as viewed from the side of the rear surface.

A reel is provided that may raise the rigidity of the hub, and suppress flange deformation that is caused by winding tension of recording tape. The reel is provided with: a cylindrical hub on which recording tape may be wound; a top flange extending integrally to the hub from a peripheral edge at one end portion of the hub; a bottom flange, including a bottom wall that has had a reel plate fixed thereto, the bottom flange being welded to a portion of the hub at the opposite end of the hub to the end of the top flange, the welding site being within the region where the reel plate is fixed.
