Display device

In a liquid crystal display comprising a plurality of pixels each of which has an switching element, a plurality of drain drivers and gate drivers for operating the switching elements and the pixels, and a plurality of drain lines and gate lines supplying signals from the drain drivers and the gate drivers to the switching elements being formed on one of a pair of substrates sandwiching a liquid crystal layer, the present invention provides wiring lines formed on the one of a pair of substrates for transferring display data signals and a clock signal between each pair of the plurality of drain drivers adjacent to one another, and provides at least one gate circuit for at least one of the plurality of drain drivers which is controlled by the clock signal and switches the display data signals and the clock signal either (1) to be acquired by the at least one of the plurality of drain drivers or (2) to be transferred to another of the plurality of drain drivers arranged adjacent to the at least one of the plurality of drain drivers. This liquid crystal display device has an advantage, for instance, or of suppressing electromagnetic interference (EMI) to another equipment surrounding the liquid crystal display device, of preventing the display data signals or the clock signal from being distorted in the wiring lines.

Differential evacuation system

[Technical Problem] To provide a differential evacuation system capable of easily maintaining, at a low cost, a large differential pressure between a light generation chamber and an illumination optical chamber in which optical processing, e.g. exposure, is performed by using extreme ultraviolet (EUV) light generated in the light generation chamber, and yet capable of sufficiently ensuring a desired optical path.
[Solution to Problem] The differential evacuation system has a light generation chamber 10 that generates EUV light, an illumination optical chamber 100 in which optical processing is performed by using the EUV light generated in the light generation chamber 10, and a chamber connecting passage 150 that connects together the light generation chamber 10 and the illumination optical chamber 100 to guide the EUV light generated in the light generation chamber 10 into the illumination optical chamber 100. The chamber connecting passage 150 has a flow path constricting portion 151 and is increased in inner diameter in a conical tube shape at portions thereof that are at opposite sides, respectively, of the flow path constricting portion 151. An enlarged-diameter part 160 is provided at a position of the chamber connecting passage 150 that is closer to the light generation chamber 10, which is the higher in pressure of the two chambers 10 and 100, than the flow path constricting portion 151, and vacuum pumps 170 are attached to the enlarged-diameter part 160.

Magnetorheological damper with built-in magnetorheological valve for damping performance control

The invention discloses a magnetorheological damper with a built-in magnetorheological valve for damping performance control, which mainly comprises a piston rod, a piston cylinder, a damper cylinder body, a valve core, a floating piston, end covers, lifting lugs and the like. The piston rod, the damper cylinder body, the valve core, an excitation coil, cylinder liquid flow passages, and U-type liquid flow passages form the built-in magnetorheological valve. When the excitation coil is conductive, flowability of magnetorheological liquid inside effective damping gaps of the cylinder liquid flow passages and the U-type liquid flow passages is reduced due to electromagnetic effects, a pressure difference is formed between a first magnetorheological liquid accommodating cavity and a second magnetorheological liquid accommodating cavity, a damping force applied to the right end surface of the piston head changes, and the purpose that the magnetorheological valve controls the damping performance of the magnetorheological damper is realized. Due to the U-type liquid flow passages, the damping length is effectively increased, and the damping force adjustable range is increased. The magnetorheological damper is particularly suitable for being applied to a shock absorption system for a railway, a train, a bridge and the like, and has the advantages of large adjustment range, compact structure and small size.
