摘要:
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.

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.

A large part of conventional organic-inorganic composite materials is obtained by mechanical blending silsesquioxanes with organic polymers, and therefore it has been very difficult to control the structure thereof as the molecular aggregate of the composite materials. An object of the present invention is to provide a novel silicon compound having a living radical polymerization-initiating ability for an addition-polymerizable monomer and a polymer obtained using the same to thereby solve the problem described above regarding the conventional organic-inorganic composite materials. The present inventors have found that a novel silsesquioxane derivative to which a group having an ability to initiate polymerization of a monomer is useful as means for solving the problem described above. That is, the silsesquioxane derivative of the present invention is represented by Formula (1): wherein R1 is hydrogen, alkyl, aryl or arylalkyl; R2 and R3 are alkyl, phenyl or cyclohexyl; and A is a group having an ability to initiate polymerization of a monomer.

A holder for a mobile electronic device includes first and second clamping jaws, at least the first clamping jaw being displaceable toward the second clamping jaw to clamp the mobile electronic device. The holder also includes a stop element and an entraining element connected to the first clamping jaw, the entraining element being shaped so that it is displaceable with respect to the stop element, namely jointly with the damping jaw connected to it, in which case at least one extreme position corresponding to the maximum opening of the clamping jaw is defined in the displacement path by the impact of the stop element against the entraining element. The holder includes a damper element, which is mounted on the stop element and damps the stopping of the stop element against the entraining element.

An image-processing device that performs image processes for pixel data of an image, to generate image-processed data. The amount of the image-processed data is greater than that of the pixel data, for each line of the image. The pixel data are stored in a recording area of a memory. The capacity of the recording area for one line's worth of the pixel data is coincident with a maximum amount of data in one line of the image-processed data. The pixel data are stored in the recording area such that a last pixel data in a sequentially stored series of pixel data for the one line is stored at an end address of the recording area.

To an original plate holder 16 to which an original pattern plate 15 is set in ordinary exposure, a transmittable plate 20 having a concave-shaped concave portion 22 formed at a middle of a quartz glass plate is set in self-cleaning and irradiated with ultraviolet light emitted from a light source 11. The ultraviolet light is diffused through the concave lens of the transmittable plate 20 and an entire surface of a projection lens 17 is irradiated with it. Accordingly, molecular bonds of a contaminant adhering to the surface of the projection lens 17 are cut off with strong energy of the ultraviolet light, so that the contaminant is decomposed, vaporized, and then removed.
摘要:
A method of manufacturing an alignment mark structure and aligning a substrate includes providing a semiconductor substrate having an upper layer, the alignment mark structure being formed on a surface region of the upper layer. The method includes providing the surface region as having opposite first and second parallel sides extending along the upper layer, with outer side walls extending upwardly from the upper layer and extending lengthwise along the side. The outer side walls are provided lengthwise with alternating first and second wall portions, each of the first wall portions being spaced farther from the first side of the surface region than each of the second wall portions. An alignment pattern is defined by providing openings in the alignment mark structure.
