摘要:
A die for molding a disk substrate capable of forming fine recessed and projected pits and grooves up to the outer periphery of the disk substrate by preventing low heat conductive elements from peeling off and burrs from occurring on the outer periphery thereof, comprising a first base die, a second base die disposed oppositely to the first base die, a first low heat conductive element fixed to the first base die, a stamper fixed onto the first low heat conductive element, a second low heat conductive element fixed onto the second base die, and a ring-like regulating member fitted to and in slidable contact with either of the first and second low heat conductive elements. The die is characterized in that the end part of the ring-shaped regulating member is positioned within the range of the outer peripheral side face of the low heat conductive element in slidable contact therewith.

A liquid crystal display comprises an array substrate in which a common electrode, a pixel electrode, a scanning signal line, a video signal line and a semiconductor switching element are provided, an opposed substrate, and a liquid crystal layer interposed between the array substrate and opposed substrate. The line width of at least either the common electrode or the pixel electrode is larger than the distance between the common electrode and the pixel electrode. The film thickness of at least one of the common electrode and the pixel electrode is larger than the thickness of at least either the scanning signal line or the video signal line.

A polymer dispersed liquid crystal display element (100) in which liquid crystal (14) is dispersed in a polymer composite (15) is provided whereby gap width distortion resulting from sudden changes in temperature is prevented, and uniformity of the display image is improved. Distortion of the gap width between glass plates due to a temperature change within a specific temperature range is prevented by dispersing spherical resin spacers (16), which are resiliently compressed a specific percentage by two glass plates (11, 12) within a specific temperature range (&Dgr;t), in a liquid crystal layer (17) interposed between a glass plate (11) and another glass plate (12) that comprise a voltage application means (18, 19, 20, 21) and are mutually opposed through a seal member (13).
摘要:
A substrate forming mold for forming a substrate by filling a cavity formed between a pair of matching molds 1, 2 with resin, that is, this substrate forming mold has shims 9, 12 disposed at least between a mirror finished surface plate 6 for composing one mold 1 and a stable mold base 8, and in a region inside of a fixed abutting ring 13, depending on fluctuations of plate thickness of formed substrate. As a result, the plate thickness of formed substrate can be adjusted finely, and fluctuations occurring in the radial direction or peripheral direction of the formed substrate can be decreased.
摘要:
A mixed material of liquid crystals and resin is dropped on at least one substrate in an amount greater than the amount needed to cover a display area for the LCD panel. The substrate is adhered to another substrate, and excess material is removed to the outside of a display area. The phase-separation of the liquid crystals and resin is carried out by irradiating light while pressure is added to at least one substrate, so that a liquid crystal display panel applied to a liquid crystal display device or a light shutter can be manufactured without applying a complex vacuum device.
摘要:
A polyurethane lens is produced by (a) adding to a monomer mixture comprising a polyisocyanate and a polythiol, a phosphoric acid ester represented by the general formula (I) ##STR1## (R.sub.1 and R.sub.2 which may be the same or different are each an alkyl group of 1-8 carbon atoms) and then (b) subjecting the monomer mixture containing the phosphoric acid ester, obtained in the step (a) to cast polymerization in a mold for plastic lens production. Said polyurethane lens has good releasability from mold, is free from color unevenness after tinting and cloudiness, and possesses high refractive index (N.sub.D) and high optical dispersion.
摘要:
A valve operating mechanism for operating a plurality of valves of a particular cylinder of an internal combustion engine includes a camshaft rotatable in synchronism with rotation of the internal combustion engine and having at least one cam. At least one of a plurality of cam followers slidably engages the cam for selectively operating the valves according to a cam profile of the cam. The cam followers are selectively interconnected and disconnected to operate the valves in different speed ranges of the internal combustion engine, the speed ranges including a range in which all of the valves remain inoperative. The camshaft has one or two annular raised portions in addition to the cam, and the cam followers include one or two cam followers which slidably engage the raised portion or portions. The valves remain inoperative by the annular portion or portions and are operated in a high-speed range by the cam, or selectively in low- and high-speed ranges by low- and high-speed ranges.
摘要:
A valve operation mode changing system for the intake or exhaust valves of an internal combustion engine is controlled in response to engine speed and temperature of the working oil utilized in the system in such a way as to permit the valve operating mode to be changed from a low-speed to a high-speed mode in response to engine speed requirements only when the temperature of the working oil exceeds a predetermined value. The system also provides for terminating fuel supply to the engine when the temperature of the working oil is below a predetermined temperature and the speed of the engine exceeds a predetermined temperature.
