Abstract: Due to a characteristic of a switching element, a current leaks into a display element in an undisplayed region through the switching element to thereby cause a speckled pattern to occur in the undisplayed region. In addition to a supply of scanning signals to scanning lines corresponding to display elements in a displayed region, scanning signals are also supplied to scanning lines corresponding to display elements in the undisplayed region to thereby inhibit the speckled pattern from occurring.

Abstract: A dip-formed rubber article is produced by dip-forming a vulcanizable rubber latex composition comprising an unsaturated nitrile-conjugated diene copolymer rubber latex, a sulfur-containing vulcanizer, and at least one vulcanization accelerator selected from (i) dithiocarbamic acid compounds of the formula (1): wherein R1 and R2 independently represent and hydrocarbon group having at least 6 carbon atoms, and (ii) zinc dithiocarbamate compounds of the formula (2): wherein R1 and R2 are as defined above.

Abstract: The invention reduces power consumption when, for example, a mobile personal computer is in a power-saving mode or when a cellular phone is in a wait mode, in an electro-optical apparatus, such as a liquid crystal display of the subfield drive type used as a display apparatus for various apparatuses. Three different settings “64”, “16” and “2” are enabled as the number of gray scale levels in an electro-optical apparatus, the number of subfields becoming smaller as the number of gray scale levels is reduced. When a large number of gray scale levels is not required (when in the power-saving mode, the wait mode, etc.), a low number of gray scale levels is set, so that the own capacitance of a liquid crystal layer and storage capacitance are charged and discharged less often.

Abstract: A shaft seal having a high abrasion resistance is disclosed, by which the leakage of the gas from the high-pressure side to the low-pressure side can be reduced. In the shaft seal, flexible leaves are multi-layered to form a ring shape. The shaft seal is mainly arranged around the rotation shaft of a gas turbine or the like. The relevant turbine comprises a casing, a compressor, a rotation shaft, moving blades attached to the rotation shaft, and stationary blades attached to the casing in a manner such that the stationary blades face the moving blades, wherein the shaft seals are provided between a plurality of stationary blades and the rotation shaft wherein the leaves of each shaft seal contact the rotation shaft. Under the rated operating conditions, the top ends of the leaves slightly separate from the surface of the rotation shaft due to the dynamic pressure generated by the rotation of the rotation shaft.

Abstract: A rotating storage apparatus is provided for high recording reliability in an environment in which a shock or vibration exists. Provided are means for outputting a shock out signal (SO) if an output from an acceleration sensor exceeds a predetermined threshold, a latch circuit 21 for outputting a latch signal at high level during a predetermined write inhibit period after the shock out signal (SO) is input, and a write gate signal (WG) which goes high when a write is enabled. A write enable signal is generated by an AND circuit 23 having a NOT output of the latch signal as well as the write gate signal WG as its inputs.

Abstract: A method to enable servo information to be detected surely and stably even when a time interval between servo sectors is changed due to disk shifting is provided. A time interval TS(i) is calculated according to an internal variable value, which is in proportion to a displacement &Dgr;r(i) of a servo area SF(i) in a radial direction of a subject disk (step S6). The displacement &Dgr;r(i) is calculated from already detected servo information, thereby a time interval for detecting servo information is adjusted according to the above-described time interval TS(i) (steps S7 and S4). The time interval TS(i) is the time interval between passing of a servo sector in the servo area SF(i) under the head H and passing of a servo sector in the servo area SF(i+1) under the head H.

Abstract: A vulcanizable dip-forming rubber latex composition comprising an unsaturated nitrile-conjugated diene copolymer rubber latex, a sulfur-containing vulcanizer, and a vulcanization accelerator comprising at least one compound selected from (i) dithiocarbamic acid compounds of the formula: and (ii) zinc dithiocarbamate compounds of the formula: wherein R1 and R2 are hydrocarbon groups having at least 6 carbon atoms which may be the same or different, and an optional thiazole compound. A rubber article dip-formed from the rubber latex composition has no crack occurrence, good surface luster and good vulcanization properties, and does not contain a nitrosamine, and therefore, is suitable for medical use.

Abstract: Disclosed is a polishing system used for polishing a surface to be polished of an object to be polished by a polishing pad, which is capable of improving uniformity of the surface to be polished of the object to be polished by positively, accurately adjusting a polishing pressure, and a polishing method using the polishing system. Concretely, the surface to be polished of a wafer as the object to be polished is polished by relatively moving, along a plane, a polishing surface of the rotating polishing pad and the surface to be polished of the wafer in slide-contact with each other, and adjusting a pressing force applied from the polishing pad to the wafer in accordance with a polishing pressure previously set depending on a relative-positional relationship between the polishing surface of the polishing pad and the surface to be polished of the wafer.
