摘要:
Provided is a shaft member for a fluid dynamic bearing device, which is excellent in wear resistance and which can exert a high dynamic pressure effect. A shaft material (11) is rolled to form a recess (7) for causing a dynamic pressure effect of a lubricating oil in a radial bearing clearance (6). In this case, in a surface layer portion (14) of the recess (7) to be formed in an outer peripheral surface (11a) of the shaft material (11), a first hardened layer (14a) is formed by rolling. At the same time, also in a surface layer portion (15) of a surrounding region (8) of the recess (7), a first hardened layer (15a) is formed by rolling at a partial region thereof. After the recess (7) is formed by the rolling, barreling is applied to the shaft material (11). As a result, an outermost surface layer portion of the surface layer portion (15) is formed with a second hardened layer (15b) by the barreling. A hardness of the second hardened layer (15b) formed in the surrounding region (8) is higher by 50 Hv or more and 200 Hv or less than that of the first hardened layer (14a) formed in the recess (7).

A device for connecting a personal audio/video player to a vehicle equipped with a FM radio. The device connects to the lighter/DC connector of the vehicle with a power block 1 to provide a source of power for the player and recharges the internal battery of the player. The device also connects to docking receptacles of a personal audio player with a receive port 6 allowing unattenuated sound and recharging connection. A wire 4 serves as an antenna for a FM transmitter 3 to make a wireless connection to the vehicle radio.

An imaging system, comprising a battery checker, an anti-shake controller, and an image processor, is provided. The imaging system is able to carry out mechanical and electronic anti-shake functions. The battery checker detects available charge of a battery. The anti-shake controller orders the mechanical anti-shake function to be carried out if the available charge is greater than a first threshold value. The anti-shake controller orders the electronic anti-shake function to be carried out if the available charge is less than the first threshold value. The image processor treats an image captured in a second area in the imaging area as a captured moving image while the mechanical anti-shake function is carried out. The size of the second area is second size, which is determined according to the available charge.

An image capturing apparatus is provided having an auto-focusing device and an image displaying device. The auto-focusing device focuses a lens on a photographing object automatically. The image displaying device displays an input image which corresponds to the photographing object and is updated periodically in a display, and displays an ornament image which covers all or part of the circumference of the input image in the display. The image displaying device displays the parts of the input image superimposed by the ornament image before said auto-focusing device finishes focusing the lens on a photographing object due to the ornament image semi-transparency, and displays the ornament image superimposed with opaque on parts of the input image after said auto-focusing device has focused the lens on a photographing object.

A digital camera has a signal processor, a high-frequency detector, a sampling processor, and a compression processor. The signal processor generates luminance and color difference data on the basis of image-pixel signals read from an image sensor. The high-frequency detector detects high-frequency components in the color difference data. The sampling processor carries out a sampling process to the luminance and color difference data in accordance with a given ratio of sampling frequencies. Then, the compression processor compresses the sampled luminance and color difference data. When there is a relatively low number of high-frequency components in the color difference data, the sampling processor samples the color difference data with a low sampling frequency.

When a self-cleaning method for an aligner is carried out, a reflecting plate having a convex lens portion is set in an original plate holder, and exposure light rays are irradiated from a light source. The surface of the lens portion is coated with a reflective film. The light rays are reflected by the reflecting plate, diffused, and emitted onto the surface of a condenser lens, thereby breaking down and removing contaminants that are adhered to the surface of the condenser lens. The light rays also enter the interior of the condenser lens to clean away contaminants that are adhered to locations other than a normal exposure path. When a concave mirror and/or a reflecting plate having 50% transmittance is used as the reflecting plate, the emission range of the light rays (i.e., the locations that are cleaned) can be changed.
摘要:
An inner space of a housing sealed with a seal member as well as internal pores of a bearing member (pores in a porous structure) are filled with a lubricating oil without the presence of air, so that the oil surface of the lubricating oil is within a seal space. Under a reduced pressure of 100 Torr, no lubricating oil leaks outside of the housing even at any attitude of the fluid lubricated bearing device such as normal, inverted, or horizontal attitude.
