摘要:
A disc-shaped recording medium for which information signals are recorded and/or reproduced in a state in which a rotating recording and/or reproducing head is floated a pre-set distance from a signal recording region carrying surface of the disc-shaped recording medium. The disc-shaped recording medium has an area radially outside of the outer perimeter of center opening by at least 0.1 mm clamped by a clamp mechanism. This area is coplanar as each surface of the disc-shaped recording medium carrying the signal recording region. It is possible in this manner to prevent eccentricity of the rotating disc-shaped recording medium and consequent collision of the recording and/or reproducing head against the disc-shaped recording medium.

It is an object of the present invention to provide a disk storage apparatus which employs a rotary actuator mechanically excellent as compared with a linear-movement actuator and can employ, in a disk cartridge, a slidable shutter that easily prevents dusts from entering the disk cartridge, and a disk cartridge therefor. The disk storage apparatus includes a disk cartridge in which a disk-like storage medium is rotatably accommodated, an apparatus body onto which the disk cartridge is detachably loaded, a shutter opening and closing mechanism provided on the apparatus body for, in an interlocking operation with an operation of attaching and detaching the disk cartridge, opening and closing a shutter capable of opening and closing a head-positioning-mechanism insertion slot of the disk cartridge, and a rotary head-positioning mechanism provided on the apparatus body for inserting a head portion for recording and/or reproducing information on and/or from the disk-like storage medium through the head-positioning-mechanism insertion slot opened when the disk cartridge is loaded,. The disk cartridge includes a slidable shutter for opening and closing the head-positioning-mechanism insertion slot by its sliding operation. The rotary head-positioning mechanism includes a rotation actuator for inserting the head unit into the disk cartridge through the head-positioning-mechanism insertion slot. According to the disk storage apparatus, it is possible to provide the disk storage apparatus which makes it difficult for the dusts to enter the disk cartridge and has a high reliability in the recording and/or reproduction.

An internal combustion engine fitted with a combustion pressure detection device includes: an internal combustion engine having a combustion chamber, a pressure detection device having a housing, a diaphragm, and a detection member, and having a shoulder part. The diaphragm is provided on the front end side of the housing and the detection member arranged inside the housing and behind the diaphragm, allowing it to detect the pressure working via the diaphragm. Also provided is a second seal member in a ring shape that seals the opening in the combustion chamber and the housing in the shoulder part of the housing in the pressure detection device.
摘要:
A cylindrical cosmetic container with an inner cap (7) inside a cap (5) fit outside an upper end of a container body (X) uses a first motion resistance at a halfway covering posture to an immediately preceding covering posture and a second motion resistance from the immediately preceding covering posture to a fully cover posture while the container body (X) is covered with the cap (5), in which the inner cap (7) includes a protrusion (7f) to deform towards an outer diameter side while applying the first motion resistance by being pressed into sliding contact with an extending upper end (4c) of the container body (X) and a projection (7d) projecting from an outer circumferential surface for applying the second motion resistance greater than the first motion resistance when a convex rib (4b) moves over the projection (7d).

This invention implements reduction in the amount of background-scattered light from a semiconductor wafer surface and highly sensitive inspection, without increasing the number of detectors. A surface inspection apparatus that detects defects on the surface of an object (semiconductor wafer surface) to be inspected, by irradiating the surface of the object with a beam of light such as laser light and detecting the light reflected or scattered from the surface; wherein a widely apertured lens with an optical Fourier transform function is disposed between the object to be inspected and a detector, a filter variable in position as well in aperture diameter is provided on a Fourier transform plane, and background-scattered light from the semiconductor wafer surface is effectively blocked, whereby only a signal from a defect such as a foreign substance is detected.

Disclosed is a heat-storage device provided with a supply pipe, a discharge pipe, and a heat-storage container that contains a heat-storage material. A heat-storage material layer comprising said heat-storage material is formed in the bottom of the heat-storage container. The supply pipe supplies a heat-carrying oil, which has a lower specific gravity than the heat-storage material, from outside the heat-storage container to the inside of the heat-storage material layer. The discharge pipe discharges the heat-carrying oil, which had been supplied to the inside of the heat-storage material layer, to the outside of the heat-storage container. The heat-storage device is also provided with a plurality of metal plates (members inside the heat-storage material layer) arranged vertically inside the heat-storage material layer. A metal plate is also disposed such that the upper end thereof is at a height greater than or equal to the vicinity of the upper surface level (L) of the heat-storage material layer. The disclosed heat-storage device is better than conventional heat-storage devices at preventing the heat-storage material from escaping the heat-storage container.
