The present invention relates to a wafer storage container which contains a semiconductor wafer one by one and provides a technology to effectively reduce adhesion of particles on semiconductor wafer surfaces during the storage of the wafer. A wafer storage container which contains a wafer one by one, includes: a wafer containing member including a domed-shape recess which abuts on a circumferential edge of the wafer and is capable of holding the wafer; and a cover member which is engaged with the wafer containing member and is capable of sealing the wafer containing member; and a wafer rear surface protection member which is formed into a shape substantially same as an opening of the domed-shape recess and comes into contact with an entire rear surface of the wafer placed so that a front surface is directed the domed-shape recess.

An optical alignment method which develops a pretilt angle by batch plane exposure without tilting a substrate. This optical alignment method provides liquid crystal aligning capability to the surface of a polymer film by exposing the surface of the polymer film through a slit exposure mask while the surface of the polymer film and the slit exposure mask are moved relative to each other substantially at a fixed rate. Alternatively, liquid crystal aligning capability is provided to the surface of the polymer film by exposing the surface of the polymer film through an optical exposure pattern while the optical exposure pattern having a plurality of lines with a certain width at certain intervals is formed on the surface of the polymer film continuously.

A radio communication device and a method of measuring distance is capable of easily obtaining a distance and a positional relation between a portable telephone 3A and a portable telephone 3B directly, not via a base station. The portable telephone 3A directly transmits a measurement pilot signal used for calculating a distance between its current position and the portable telephone 3B, to the portable telephone 3B via a radio interface for short distance 15, receives a pilot response signal in response to the measurement pilot signal from the portable telephone 3B, and then calculates a distance between the portable telephone 3A and the portable telephone 3B based on the pilot response signal and the measurement pilot signal, thus making it possible to easily obtain a distance and a positional relation between itself and the portable telephone 3B by directly communicating the pilot response signal and measurement pilot signal with the portable telephone 3B, not via the base station.

A disk cleaner includes a polishing member that is rotated while it is pressed against a surface of a disk to be polished to thereby polish the surface of the disk and an air cooling apparatus that cools the disk by causing outside air to flow along the surface of the disk. The air cooling apparatus is incorporated integrally with the disk cleaner. The cooling apparatus inhibits the peeling of the adhered surfaces as well as the generation of cracks of a DVD of a two-ply structure.

The rotary vessel is structured having a function movable generally vertical relative to a plane of a wristwatch case, and divided with a plurality of stop points in a movable range in a vertical direction, i.e. a stop point for securing stop stability of rotation and a stop point for rotating the rotary vessel. Due to this, in the case that the rotary vessel is in a rotatable state, rotation torque can be minimized.

A recording medium reproducing apparatus includes: an apparatus main body having a recording medium insertion opening; a flap body adapted to be attached to the apparatus main body so as to close the insertion opening; a first gear formed on the flap body, the first gear being coaxial with pivotal shafts of the flap body; a second gear provided in the apparatus main body and engageable with the first gear formed on the flap body; an arm member protruding from the front side of the apparatus main body, the arm member being retractable into the apparatus main body upon being pressed by the flap body when the flap body is closed on the apparatus main body; an interlock mechanism for simultaneously effecting the protrusion or retraction of the arm member and the rotation of the second gear provided in the apparatus main body; a first urging device for urging the interlock mechanism so as to cause the arm member to outwardly project to its fully projected position. Therefore, the above arm member may be urged to its projected position so as to open the flap body.

摘要:
An optical isolator having a constitution in which a Faraday rotator is sandwiched by two polarizers, which can be more easily produced at a reduced cost. An optical isolator is constituted so that it comprises the following constituent elements in the described order: a first reflection-type polarizer made of a polymeric multilayer film; a Faraday rotator capable of rotating the polarizing. plane by 45 degrees; a tapered glass plate; and a second reflection-type polarizer made of a polymeric multi-layer film.

In a combined, small-sized, portable video/still camera system, it is intended to improve the reliability against a rise in internal temperature of the system and improved reliability against vibration, while keeping small the external size of the system. Such compact system includes a PCMCIA hard disk drive capable of being loaded to, and removed from, the image recording/reproducing system. According to the present invention, as set forth hereinabove, a plate or medium formed of a thermally conductive rubber or copper (higher in thermal conductivity than air) is mounted on an encoder LSI package attached to a side of a circuit board opposite to the hard disk mounted side, and such medium is arranged to conduct heat to the system housing formed of aluminum or other material high in thermal conductivity. As a result, the housing is efficiently used as a heat sink. The hard disk is disposed centrally in the interior of the system, and thus an impact or vibration exerted on the exterior of the system is transmitted to the hard disk only through the mounting frame, so that the impact or vibration is relatively diminished. As an additional advantageous arrangement, the LSI package surface and the system housing are drawn very close to each other, for example not larger than 2 mm in terms of the spacing between the two, such that the heat of the LSI package can be transferred to the system housing at a high efficiency.
