摘要:
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).

An active matrix liquid crystal display for projection system comprises a light shielding layer 12 arranged between a layer 13 including thin film transistors and a first substrate 11 for shielding an injection light toward each of the thin transistors, said light shielding layer 12 having a plurality of openings through which each of the pixel electrodes 22 is exposed against the injection light. The light shielding layer 12 is preferably made of metal and is connected to an electric source. A level of voltage applied on the data lines is adverse to that applied on the light shielding layer with respect to polarity of the applied voltage.

An optical disk substrate which includes a plurality of sectors, tracks alternately formed into lands and grooves in a direction intersecting at right angles with a tracing direction during recording or reproducing of information, a first pit row having address information and formed at a specific position of the track of a predetermined one land or groove, and a second pit row having address information and formed in a different track neighboring the track formed with the first pit row in the tracing direction, and formed at a position deviated longer than a length of the pit row from the specific position. By the above arrangement, the address information can be read without interference, with reduction of waiting time for reading.

A cylinder block as a main part of an engine block includes a cylinder barrel assembly block, a skeleton-like frame surrounding the outer periphery of the cylinder barrel assembly block and a plate-like rigid film member, within a fluid passage in the skeleton-like frame. The skeleton-like frame is integrally joined to the outer surfaces of left and right side walls of the assembly block along the crankshaft axis and includes crossbeam bone members, longitudinal beam bone members and post bone members which are rigid and unitarily assembled into a three-dimensional latticework structure. A cylinder head is integrally coupled to the deck surface of the cylinder block and a lower case is integrally coupled to the lower surface of the cylinder block, lateral outer surfaces of the block and lower case along the crankshaft axis being formed flush with each other in parallel with the cylinder bore axis. The lower case includes a lower case frame of three-dimensional latticework structure and rigid film members at least on the lateral outer surfaces of the lower case frame along the crankshaft axis. Moreover, the lower case is secured to the lower surface of the cylinder block by bolts and an oil pan is floatingly carried on the lower surface of the lower case via resilient members. The cylinder block has at its one end surface along the crankshaft axis a square, transmission mating surface and a divergent bulged portion extending from a rear part of the cylinder block toward the mating surface.

A hydrostatically operated continuously variable transmission includes a cylinder block centrally coupled to a transmission shaft coupled to an engine, a swash-plate-type axial-piston hydraulic pump having a group of pump plungers, a hydraulic motor having a group of motor plungers, and a closed hydraulic circuit by which the hydraulic pump and the hydraulic motor are interconnected. The groups of pump and motor plungers are disposed in annular patterns in the cylinder block, and disposed concentrically such that one of the groups surrounds the other group. The plunger groups are positionally displaced in the circumferential direction of the cylinder block such that a circle inscribed in said one group passes through the other group.
摘要:
A valve operating mechanism for operating a single valve 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, and a plurality of cam followers, one of which 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 valve differently in different speed ranges of the internal combustion engine. In different embodiments, the camshaft has an annular raised portion and low- and high-speed cams, or low-, medium-, and high-speed cams, or an annular raised portion and a cam, and the cam followers are held in sliding contact with these raised portion and cams. The valve is selectively kept inoperative by the raised portion and operated in low- and high-speed ranges by the low- and high-speed cams, or selectively operated in low-, medium-, and high-speed ranges by the low-, medium-, and high-speed cams, or selectively kept inoperative by the raised portion and operated in a high-speed range by the cam.
摘要:
A valve operating mechanism includes a camshaft rotatable in synchronism with rotation of an internal combustion engine and having a plurality of cams of different cam profiles. First, second, and third rocker arms are held in sliding contact with the cams, respectively, for operating the valves according to the cam profiles of the cams. The rocker arms are selectively interconnected and disconnected by first and second selective couplings to operate the valves at different valve timings in low, medium, and high speed ranges of the internal combustion engine.
摘要:
A motorcycle having an engine with a turbo-supercharger is disclosed herein. A rear fork is pivoted to the frame member for vertical oscillation and the supercharger is disposed at the back of the engine below the pivot point of the rear fork relative to the frame member so that it can be installed in an exposed manner for effective cooling and protected from contact with other obstacles without interference with other members.
