摘要:
In a radiation detector according to this invention, a portion of a semiconductor, located in a connection of a common electrode to a lead wire, is dented in a recess form from other portions of a semiconductor, in a range short of a radiation detection effective area. An insulating seat is disposed to fill the portion located in the connection. The common electrode is formed to cover at least part of the seat. The lead wire is connected to a portion of the incidence surface of the common electrode located on the seat. Thus, the detector can avoid performance degradation resulting from connection of the lead wire to the common electrode, and avoid problems of heat deformation stress and radiation attenuation.

An object is to provide a highly efficient compressor while improving a refrigerant leakage, enhancing a performance of a compressor, improving durability, and enhancing reliability. The compressor comprises: a compression element comprising a cylinder in which a compression space is constituted; a suction port and a discharge port which communicate with the compression space in the cylinder; a support member which closes an opening of the cylinder; a rotary shaft which is rotatably supported by a main bearing as a bearing formed on the support member; a compression member whose one surface crossing an axial direction of the rotary shaft is inclined continuously between a top dead center and a bottom dead center and which is disposed in the cylinder to be rotated by the rotary shaft and which compresses a fluid sucked from the suction port to discharge the fluid via the discharge port; a vane which is disposed between the suction port and the discharge port to abut on one surface of the compression member and which partitions the compression space in the cylinder into a low pressure chamber and a high pressure chamber; and a shaft seal which is disposed on an end portion of the bearing (main bearing) on a side opposite to the compression member and which abuts on the rotary shaft.

A catalyst body includes a catalytic layer containing an alkali metal and/or an alkaline earth metal and a carrier carrying the catalytic layer, characterized in that the carrier has a porosity of 40% or below. According to this catalyst body, the invasion of the alkali metal and/or the alkaline earth metal contained in the catalytic layer into the inside of the carrier is inhibited and thus the carrier can sustain the strength and NOx absorptivity required as a carrier over a long period of time even upon exposure to a high temperature.

An optical pickup device is provided which includes a first diffraction grating (45) that splits a light beam emitted from a light-emitting/-detecting element (31) into a zero-order light beam and positive and negative first-order light beams, a second diffraction grating (46) that diffracts return light from an optical disk (2) for traveling along a light path separate from that of the outgoing light, and a third diffraction grating (47) that corrects the deviation of the light path by diffracting the positive first-order light beam diffracted by the second diffraction grating (46). The light-emitting/-detecting element (31) provides a focusing error signal FE by detecting the negative first-order light beam, and a tracking error signal by detecting return portions of the positive and negative first-order light beams from the first diffraction grating (45).

A nonvolatile memory device includes source and drain regions formed in a semiconductor substrate, and an insulating film formed on a channel region between the source region and the drain region in the semiconductor substrate. The nonvolatile memory device also includes a dielectric film formed above the channel region to store electric charge, and a control gate formed on the dielectric film. Compressive stress in the channel region is equal to or less than 50 MPa.
摘要:
A catalyst body is obtained by loading, on a carrier, a catalyst layer containing an alkali metal and/or an alkaline earth metal, wherein at least one kind of alkali metal and/or alkaline earth metal is allowed to be present in the carrier and/or between the carrier and the catalyst layer. With this catalyst body, the deterioration of the carrier caused by the alkali metal, etc. is prevented effectively and the long-term use has been made possible.

It is sought to provide a form evaluation system, which permits clear visual comparison of an ideal form and the own form on an image and accurately understanding points to be improved. A database is formed with check points of the form in golf, for instance, as reference data of form evaluation. A predetermined division number of still images are produced from motion picture image data of subscriber, these still images are displayed on a personal computer display screen, the form of the subscriber's still images is evaluated with the database as reference, and on the basis of the evaluation a form evaluation sheet is produced, which contains a predetermined division number of serially changing still images and form guide comments each provided for each of these still images.
