摘要:
A spindle motor (50) is composed of a base (8), a sleeve (4) in cylindrical shape that is fixed on the base (8), a shaft section (1) inserted into a through hole (4b) of the sleeve (4) that is rotatable with respect to the base (8), a hub (7) that rotates together with the shaft section (1), a radial dynamic pressure bearing section (RB) formed between a bushing (13) and the sleeve (4), a flange section (4a) that protrudes in a radial direction on an outer circumferential section of the sleeve (4), a wall section (7a) in annular shape that protrudes with surrounding the sleeve (4), a thrust ring (3) that is fixed on an inner circumferential section of the wall section (7a) being adjacent to the flange section (4a) and the bushing (13) in an axial direction, and a seal plate (17 fixed on an outer circumferential section of the sleeve (4) with sandwiching the thrust ring (3) between the flange section (4a) of the sleeve (4) and the seal plate (17) in an axial direction. The spindle motor (50) is furnished with a first thrust dynamic pressure bearing section (SB1), which is formed between confronting surfaces (3a, 4a1) of the thrust ring (3) and the flange section (4a), and a second thrust dynamic pressure bearing section (SB2), which is formed between confronting surfaces (3b, 17a) of the thrust ring (3) and the seal plate (17).

In a second horizontal plate (18a) bottoming an atmosphere recovery box (18), there are formed circular holes (21) between blowout pipes (20) adjacent to each other. Each of partition walls (2) positioned above a conveyor (5) includes an upper portion formed from a heat-insulating wall (2a) including a heat-insulative material having a thickness of T, and a lower portion formed from a metallic-plate wall (2b) extending downward from the heat-insulating wall (2a) toward the conveyor (5). The pitch P2 of the blowout pipes (20) across the metallic-plate wall (2b) is substantially same as the pitch P1 (12 mm) of the blowout pipes (20) disposed inside each of the chambers (R1 to R5) and adjacent to each other.
摘要:
In an optical transmission module having a communication module which is freely movable in a case, when a tensile force is generated on an optical cable after connection of an optical transmission module, optical coupling surface and an optical axis center follow each other and thus stable optical transmission can be constantly performed.
摘要:
A camera or other sensing unit senses the conditions of articles and mobile entities, including humans within a living space. An article management/operation server manages, within an article database, attribute information about the articles, including operators, according to the information from the sensing unit. The server receives a user's instruction, input through a console unit, and refers to the article database to convert this instruction into a control command, which is then transmitted to a life-support robot.

A sensing unit, such as a camera, or the like, senses the conditions of articles and mobile existences, including humans, in a life space, such as a house of a household, or the like. An article management/operation server manages, on an article database, attribute information of the articles, which include operators, etc., according to the information from the sensing unit. The server receives a user's instruction input through a console unit and refers to the article database to convert this instruction to a control command, which is then transmitted to a life-support robot.

A gamut judging apparatus of the present invention has source color distance calculator 1 that calculates the length of a source color vector connecting a source color as an object to judge whether the source color is in or out of gamut of a device and a center color set in the gamut, gamut distance calculator 3 that calculates a gamut distance between the center color and an intersection at which the source color vector or an extended source color vector intersects a gamut boundary of the device, and a judging section that judges that the source color is out of the gamut of the device when the length of the source color vector is larger than the gamut distance, and judges that the source color is in the gamut of the device when the length of the source color vector is smaller than the gamut distance.
摘要:
The present invention relates to a scanning electron microscope employing a deceleration field forming technology (retarding), more particularly a scanning electron microscope which separates and detects secondary electrons at high efficiency. The object of the present invention is accomplished by providing an electron source, a lens for condensing the primary electron beam which is emitted from said electron source, a detector for detecting electrons which are generated by radiation of the primary electron beam onto a specimen, a first deceleration means for decelerating the primary electron beam which is radiated onto said specimen, a second deceleration means for decelerating electrons which are generated on the specimen, and a deflector for deflecting said electrons which are decelerated by said second decelerating means.
