Abstract: PROBLEM TO BE SOLVED: To provide a voltage detector which allows improvement of the sensitivity in voltage sensing to a great extent, can widen the degree of freedom of the inpendance matching characteristics of an electrode part for modulation, and can work well with voltage sensing for high frequency signals over one GHz. SOLUTION: This voltage detector is equipped with the first Y-branched waveguide path 1, a pair of electrodes 4 and 5 installed over and under a waveguide path 3a, and the second Y-branched waveguide path 2, and the impressed voltage between the electrodes 4 and 5 is determined on the basis of the intensity of the output light from the second Y-branched waveguide path 2. Because of provision of the electrodes 4 and 5 in the described arrangement, the sensitivity in voltage sensing is improved to a great extent, and will be further improved if the waveguide paths are formed from an organic material.

IPC: F16D65/18
Filed: 1991-02-08
Abstract: PURPOSE:To facilitate exchange of a pad of an inverse actuation disc brake device, which maintains constant the stroke of a lever to rotate a cam, by opening with a cam a pair of carries, which press a friction pad against a disc while constantly receiving the strength of a pressurized means, and thereby releasing the brake, and also providing an automatic adjusting device for pad abrasion. CONSTITUTION:A means to restore the position of a carrier is composed by providing a screw hole 17 on a housing 11 fixed to a carrier 2 and screwing a return bolt 18 into the screw hole 17. When the return bolt 18 is turned after making it contact the rear end of an adjusting bolt 12 with a clutch 15 in a disengaged state as shown in the drawing, an adjusting bolt 13 or an abrasion adjusting device turning into a reaction force supporting member and the housing into a propulsion transmission member, cause the carrier 2 to open as the adjusting bolt 12 turns and, simultaneously, the relative positions of the adjusting bolt 12 and the carrier 2 are restored to their original positions, thus the pad can be exchanged without releasing the strength of the pressurized means which constantly applies the closing force to the carrier.

A notch 6 is provided in the tube 5 in a position, allowing the notch to coincide with the through-hole 3 in the pipe body 1, to form a flexible tong-shaped valve body 7. When a water pressure in earth, in which a drainage pipe is buried, is higher than the pressure of the interior of the tube 5, the valve body 7 is forcibly opened inwardly, underground water therearound enters the tube 5, and the water is drained through the pipe. When a water pressure in the pipe is increased or an internal pressure is increased over an external pressure resulting from an increase in a water pressure outside the pipe, the valve body 7 is pressed by dint of the internal pressure and is forced into firm adhesion to the inner surface of the pipe body 1 to close the through-hole 3.
