摘要:
The controlling apparatus includes a wire supplying sensor 18 for detecting a number of rotations of a wire supplying motor 8, a wire twisting sensor 49 for detecting actuation of a loaded torque detecting mechanism c, and a return position detecting sensor 38 for detecting that a wire twisting mechanism b is located at a predetermined waiting position. In response to an output signal from the wire supplying sensor 18, the controlling apparatus stops rotation of a wire supplying motor 7a and rotationally drives a wire twisting motor 7b. In addition, in response to an output signal from the wire twisting sensor 49, the controlling apparatus shifts rotation of the wire twisting motor 7b in the normal direction to rotation of the same in the reverse direction. Additionally, in response to an output signal from the return position detecting sensor 38, the controlling apparatus stops rotation of the twist driving motor 7b.When a start switch 5 is actuated with an operator's hand the controlling apparatus makes it possible to sequentially perform supplying of a predetermined length of binding wire 2, rotating of a twisting shaft 25 until a predetermined torque value is reached, and returning of the wire twisting mechanism b to the initial position.

摘要:
A method for producing carbamates that enables carbamates to be produced at low costs, with high selectivity and high yield, and in a simple manner, and a method for producing isocyanates that enables isocyanates industrially used to be produced by using the carbamates obtained by the carbamates producing method. Nonaromatic amine selected from the group consisting of aliphatic amine, alicyclic amine, and aralkyl amine is allowed to react with alkylaryl carbonate to thereby produce carbamates. Also, the carbamates thus obtained are thermally decomposed to thereby produce isocyanates. When carbamates are produced in this method, alkyl carbamates can be obtained with high selectivity and at high yield by using simple equipment. Also, when isocyanates are produced in this method, polyisocyanates used industrially as the raw material of polyurethane can be produced in a simple manner and with efficiency.

A lens array sheet, a transparent screen using the same, and a rear-projection display device are provided in which it is possible to control a perspective angle for the image in both a horizontal direction and a vertical direction without causing a problem in that a gain (brightness) of a light is reduced by an optical absorption and an S/N ratio is reduced by an increased white dispersion.A first lens array 18 and a second lens array 20 which are formed by disposing a plurality of half-cylindrical lenses 17, 19 in parallel on a common plain (a surface of a base member layer 13a) such that longitudinal directions of the cylindrical lenses 17, 19 should be orthogonal to each other. Unified lens array layer 13b and a shading layer 16 in which a section through which a light does not transmit is formed on a focal plain of the lens array layer 13b form a lens array sheet. Furthermore, fresnel lens are combined so as to form a transparent screen.

In a vacuum gate valve, a seal member for sealing a gate opening part is bonded to an outer edge part of a planar seal plate that is disposed in such a manner that the planar seal plate is opposed to a valve seat surface of the gate opening part and comes into contact with the valve seat surface. The seal member includes a vacuum seal part that is located on a side farther from the gate opening part and maintains the sealability of the gate opening part when the gate opening part is closed, and also includes a radical seal part that is located on a side closer to the gate opening part and that prevents the seal member from being affected by a treatment gas in the gate opening part when the gate opening part is closed. The vacuum seal part is made of a rubber elastic body, and the radical seal part is configured by providing a radical resistant body that is provided with an excellent radical resistance on the rubber elastic body.
