    摘要: A homogeneous electro rheological fluid is provided. The fluid comprises a lyotropic liquid crystalline polymer dissolved in a solvent in low concentrations in a manner in which the fluid does not exhibit a liquid crystalline state. According to the homogeneous electro rheological fluid of the present invention, the problem associated with the precipitation of particles can be circumvented. Moreover, the electro rheological fluid can provide a large difference in torque before and after the application of an electric field; therefore, exhibits good electro theological properties. The electro rheological fluid according to the present invention can be used in making engine mounts, damping apparatuses, clutches, torque converters, braking systems, valves, dampers, suspensions, actuators, vibrators, ink jet printers, and the like.

    摘要: A method of manufacturing a thin-film transistor which comprises the steps of forming a gate electrode on an insulating substrate, a gate insulating film covering the gate electrode, and an i-type a-Si layer on the gate insulating film, forming a blocking film made of metal such as Cr or the like on a channel-forming region of the i-type a-Si layer, and forming an n-type a-Si layer covering the i-type a-Si layer and the blocking film, forming a metal layer on the n-type a-Si layer, and etching a predetermined portion of the n-type a-Si layer and a predetermined portion of the metal layer, thereby forming a source electrode and a drain electrode. That portion of the blocking film which is located below a gap between the source electrode and the drain electrode is removed from the i-type a-Si layer.

    摘要: A code reading apparatus of a bar code reader which has detecting means for outputting a reading signal responsive to the code displayed on a medium, edge detecting means for detecting the edge of the reading signal, counting means for starting counting each edge detected by the edge detecting means. Discriminating means outputs a reset signal to decoding means when the counted value started for counting by the counting means is a product or more of the quotient produced by dividing the allowable maximum width of the code by the allowable minimum width and the counted value counted between the edges immediately before by the counting means, when the quotient produced by dividing the counted value started for counting by the counting means by the counted value counted between the edges immediately before is a quotient or more produced by dividing the allowable maximum width of the code by the allowable minimum width. Thus, the apparatus can discriminate the start even if the starting margin before the code of the bar code is short.
