  • Publication number: 20210072572
    Abstract: A light control device including a light control sheet including a light control layer switchable between at least a first state and a second state by changing alignment of liquid crystal molecules by application of a drive voltage, and transparent electrode layers sandwiching the light control layer. The light control layer is transparent in the first state and turbid in the second state. The light control layer is in the second state when there is no application of the drive voltage. When the light control layer is in the second state, the light control sheet has a transmitted image definition of 70% or less, where the transmitted image definition is based on JIS K 7374:2007 with an optical comb width set to 0.125 mm.

  • Patent number: 7174594
    Abstract: A car washing machine (1) is composed of a front body (1A) provided with a rocker brush (11), a top brush (12), side brushes (13) and so forth as washing means for washing a vehicle (2), and a rear body (1B) provided with a top nozzle (21), side nozzles (22) and so forth as drying means for drying the vehicle (2). The front and rear bodies (1A and 1B) are capable of separately traveling. According to this arrangement, the washing operation of the vehicle (2) using the washing means provided on the front body (1A) and the drying operation using the drying means provided on the rear body (1B) can be executed in a spaced apart relationship, thus preventing the drying finish from being deteriorated by water splashes produced during the washing operation.

  • Patent number: 6688339
    Abstract: A high-pressure composite pipe of the present invention comprises an inner layer pipe made of a synthetic resin, and a reinforcing layer formed by spirally winding a stretched polyolefin resin sheet on an external circumferential surface of the inner layer pipe. The synthetic resin for the inner layer pipe or a heat-sealable resin is filled into a gap defined by the stretched polyolefin resin sheet, thereby avoiding penetration of water from a cut surface of the pipe.

  • Publication number: 20040007279
    Abstract: As the first object, the present invention intends to provide high-pressure composite pipes which show remarkable pressure resistance and optimum applicability in various uses and which can be economically manufactured in a light weight. As the second object, the present invention intends to provide a joining method which is capable of firmly joining the high-pressure composite pipes in a simple operation, firmly joining the high-pressure composite pipes by reinforcing the joint strength at the butt-fused area, and making a joint area adjustable to strain of the high-pressure composite pipes. To achieve these objects, a high-pressure composite pipe of the present invention comprises a pipe-shaped inner layer made of a synthetic resin, a reinforcing layer made of a stretched polyolefin resin sheet and wound on an external circumferential surface of the inner layer, and an outer layer made of a synthetic resin and disposed on an external circumferential surface of the reinforcing layer.
