摘要： PURPOSE:To measure the amount of displacement of a measuring point by a simple structure at a remote position, by fixing a moving pulley at the measuring point, fixing fixed pulleys at a reference position, hooking a piece of wire rope on the pulleyes, and detecting the rotation by a rotary angle sensing part. CONSTITUTION:A moving pulley 2 is provided at a measuring point 1. Fixed pulleyes 4 and 5 are provided at a reference position 3. A piece of wire rope 6 is hooked on the pulleyes. A weight 7 is suspended at both tips 6a and 6b of the rope in order to impart suitable tension. An angle detector 8 is coupled to the reference position 3 so that the axis of the detector is the same as the rotary shaft of the pulley 5. The amount of displacement of the measuring point 1 can be detected by the angle detector 8.

摘要： PURPOSE:To make construction simple and attaching and handling easy by having >=2 stationary pulleys which are fixed at pivotal supporting parts in a reference position so as to parallel approximately with the displacing direction of a measuring point apart at a prescribed distance from each other. CONSTITUTION:Two stationary pulleys 4, 5 of which the pivotal supporting parts, i.e., brackets, are respectively fixed so as to parallel with the displacing direction 1a of a measuring point 2 are provided in a reference position 3 apart at a prescribed distance from each other. The device is so arranged that the rate of displacement of the point 1 is absorbed by the rotation of a running block 2 when the sum of the wire length among the blocks 2, 4, 5 changes according to the displacement of the measuring point 1. A weight 7 as a tension applying means applies tension equally to wire ropes 6. The construction is thus made simple and the attaching and handling are made easy.

摘要： PURPOSE:To measure two-dimensional displacement quantity, by mounting a displacement converter or a first angle detector outputting the electric signal corresponding to the moving quantity of a wire rope and a second angle detector outputting the electric signal corresponding to the angle of rotation of a running block. CONSTITUTION:The moving quantity of one point 6 of a wire rope 6 at a reference position 3 is set to d1, the winding-in quantity or pay-out quantity of the wire rope 6 to a running block 2 at a measuring point position to d2 and the distance between the perpendicular V passing the center point 0 erected from the straight line AB on a plane ABC and a point C to P1. Now, when it is assumed that a measuring point 1 moved from the point C to a point C' with respect to the reference position 3, the up-and-down direction displacement quantity Dv and horizontal direction displacement quantity Dh of the measuring point 1 are calculated from formulae I, II. The electric signals corresponding to d1 and d2 outputted from a displacement meter 8 and an angle detector 9 are inputted to an operator performing addition, subtraction, multiplication, and division and square etc. and operated on the basis of the formulae I, II to obtain the vertical direction displacement quantity Dv and horizontal direction displacement Dh of the measuring point 1.

摘要： PURPOSE:To improve the accuracy of measurement, by fixing both ends of plural ends of leaf springs to a friction member and a stationary member, and providing a force detecting mechanism which detects the force transmitted from the friction member. CONSTITUTION:A friction member 1 wherein the material of the same kind as the material of a structure into which said member is embedded and installed is stuck in the part of the material of the same kind formed with the friction surfaces of suitable areas of the material of the same kind, and which makes the same action as the action of the member constituted of the material of the same kind, and a stationary member 2 to be embedded and fixed into the structure are provided. Both ends of two sheets of leaf springs 3 which can deform slightly in the friction directions are fixed to the member 1 and the member 2. A force detecting mechanism 4 using a load cell LC in order to detect the force in the friction direction transmitted from the member 1 is fixed between the member 1 and the member 2.

摘要： PURPOSE:To enable measurement of a feed value to be effected at a high accuracy by providing a feed value setter, an error computing section and a target reference value computing section. CONSTITUTION:A measured weight as feed value detected by a feed value detecting means and a reference value are compared with a feed storage judgment section 23 which outputs a closure direction signal when the measured weight is larger than the reference value to close a feed port of a supply container. Thereafter, the measured weight is detected by the feed value detecting means again and the reference value is subtracted from the measured value by an error computing section 19 to calculate a feed error value. Moreover, the feed error value is subtracted from a forecast feed value preset on a feed value setter 10 by a target reference value computing section 20 to calculate a target reference value. Thereafter, this error computation is repeated. It should be noted that the reference value employs a target reference value calculated by the computing section 20 at the (N-1) th operation (wherein N is integer of N>1) and computation for correction of errors is repeated to update the target reference value sequentially.
