摘要:
Proposed is a novel casing for frame-supported pellicle used for dustproof protection of a photomask in the photolithographic patterning process for the manufacture of fine electronic devices. Different from conventional casings made from a plastic resin, the casing of the invention is characterized by the use of a unique permanently antistatic resin composition which is a resin blend consisting of 80-95% by weight of an ABS or acrylic resin and 20-5% by weight of a specific hydrophilic polymer. By virtue of the excellent antistatic behavior of the resin composition, the frame-supported pellicle encased in the casing is safe from the troubles due to deposition of dust particles during transportation and from contamination by the vaporized matter from the casing.

Disclosed is a method for recovery of a metal using plants. The method for recovery of a metal involves bringing a protonema of a moss plant belonging to the family Funariaceae into contact with a metal-containing solution in which a metal(s) having an ionization tendency lower than that of silver is dissolved.

A workpiece W2 is grasped by inserting a first jig into a concave portion which is formed in a rotor forming process, and by interfitting a second jig to a convex portion which is also formed in the rotor forming process. Thereby, the workpiece W2 is firmly grasped, and a groove-forming roller can be strongly pressed into the workpiece W2. A time for forming a pulley groove is shortened, and a manufacturing cost thereof is reduced.

In a film feed device using a film having two perforations per frame, a perforation width and a perforation interval which are detected by one perforation sensor during a film feed operation are measured as times by timers in a microcomputer or as film moving amounts by a perforation detection circuit. When the time or the film moving amount measured as this perforation interval is less than the value obtained by multiplying the perforation width by a predetermined value, the film feed operation is stopped by a motor driving circuit and a motor. With this operation, even if the film position deviates from a predetermined position at the start of a film feed operation, the film can be accurately aligned with a correct position by using one perforation sensor.

Apparatus for fabricating a cellular laminated material from two plastic sheets includes a molding rotatable cylinder in contact with a pressure rotatable cylinder. Cooling water injection and air removal are accomplished within the interior of the molding cylinder. The contact portion of the two cylinders receives one of the plastic sheets. The other plastic sheet is cooled, heated and stretched prior to its being fed for embossing and laminating with the other plastic sheet on the molding cylinder. One embodiment has ends on the molding cylinder to provide an air-tight enclosure and the other embodiment is open at the ends thereof.

In an electromagnetic clutch, a rotor, an armature and a stator housing including an electromagnetic coil are assembled to a center hub through a bearing member. Therefore, by assembling the center hub to an engine crank shaft, an assembling operation of the electromagnetic clutch to a vehicle is finished. In addition, a stator plate fixed to the stator housing is fixed to an engine through a bushing made of an elastic material. Therefore, a vibration displacement of the stator housing relative to the rotor, generated due to vibration of the engine, can be absorbed.

Disclosed is a frame-supported pellicle, which is an integral body consisting of a rigid frame and a transparent plastic film adhesively bonded to one end surface of the frame in a slack-free fashion, for dustproof protection of a photomask used in a photolithographic patterning work in the manufacture of fine electronic devices such as LSIs and liquid crystal display panels. The frame-supported pellicle is prepared by bonding the frame and plastic film with an adhesive having a glass transition temperature substantially lower than that of the polymeric resin forming the film and the adhesive bonding work is performed at a temperature higher than the glass transition temperature of the adhesive but lower than that of the polymeric resin of the film so that excellent adhesive bonding strength can be obtained between the frame and the resin film still without causing any adverse influences on the resin film such as distortion and crease formation.
摘要:
A camera device (1) is provided with an imaging unit (3) for outputting a long exposure signal and a short exposure signal within one field period; a knee processing unit (12) for compressing a long exposure signal having the luminance level of a knee point or higher at a predetermined compression rate (i.e., decreasing the inclination of an incident light amount-luminance level line representing the variation of a luminance level with the amount of incident light); and a knee control unit (14) for adjusting the knee point and the compression rate according to the luminance level of a synthesized signal obtained by synthesizing the long exposure signal and the short exposure signal. In this knee control, the knee point and the compression rate are adjusted, so as to make the knee point lower with an increase in the luminance level of the synthesized signal of the long exposure signal and the short exposure signal and revert the inclination of the incident light amount-luminance level line to the original state thereof. Consequently, it is possible to obtain an image sharply contrasted in bright parts within a screen.
