Title: Absolute angle measuring instrument
Inventor: KITAHARA RYOICHI
IPC: G01B11/26
Filed: 1986-07-04
Abstract: PURPOSE:To measure the movement quantity of a body to be measured with simple structure by rotating a cylindrical lens which varies the refractive angle of incident light according to rotation by a driving means coupled with the rotary shaft whose angle is to be measured, and detecting the angle of rotation from its outgoing light. CONSTITUTION:The hollow homogeneous cylindrical lens 1 which is so worked that the internal circle and external circle shift in center axis from each other is fitted to a holder 2. This holder 2 is coupled with the rotary shaft 3 whose angle is to be measured through a coupling 4. Consequently, the lens 1 rotates as the rotary shaft 3 rotates. Then, a prism 5 is fixed in the lens 1 independently of the lens 1, and consequently laser light outputted by a laser oscillator 6 is refracted by 90 deg., made incident on the lens 1 from its internal circle, and projected from its external circle. The output laser light is photodetected by the photodetector 7 composed of photodetecting elements 71-7n. Therefore, the photodetection position 7n of the photodetector 7 corresponding to the angle of rotation of the rotary shaft 3 and therefore lens 1 one to one is easily detected and the absolute value of the angle of rotation of the body to be measured is measured.

Abstract: PURPOSE:To raise the efficiency of excavation as well as lengthen the mechanical life of an excavator by providing a system in which a reciprocal vibration in the turning direction is generated for a bucket by a mechanical vibration generator for an excavator in which the bucket pivotally supported on an arm is turned. CONSTITUTION:A link 8 is pivotally supported on an arm b, the other end of the link 8 is pivotally attached to the connecting point between a bucket cylinder (a) and a reciprocating cylinder 1 as a mechanical vibration generator and thereby the bucket (c) is smoothly turned. The reciprocating cylinder 1 gives a reciprocal vibration in the turning direction to the bucket (c) by alternately charging and discharging a working oil to and from oil chambers 13 and 14 on both sides of the piston by a rotary valve 6 driven by an oil-pressure motor 7. By the reciprocal vibration, the frictional resistance in soil of the bucket (c) can be reduced and the bucket (c) can thus be penetrated easily while crushing rock bed, etc. Thus, effective excavation can be attained. Also, by adjusting the motor 7, the frequency can be selected according to the quality of rock bed and soil.
