Filed: 1983-07-15
Abstract: PURPOSE:To improve the maximum measuring level of incident optical power and to obtain a wide dynamic range by impressing a reverse bias voltage which is zero or minute at a region having a small incident light power and large at a region having large power to a photo diode.

Abstract: PURPOSE:To secure at all times an excellent brake operation characteristic without a slide resistance against a pin member becoming large by forming at the sliding portion of the hole of a cylinder main body a film by means of an anodic oxidization treatment. CONSTITUTION:A piston P within a cylinder portion 2 slides forward through a cylinder hole by receiving a liquid pressure from a master cylinder, and a caliper 1 consisting of the cylinder portion 2 and a push-pressing portion 3, is constituted so that it may move in the opposite direction to that of the piston due to reaction force.

Title: Measuring instrument for rotational frequency
Inventor: NEMOTO HIROSHI
IPC: G01P3/486
Filed: 1985-06-15
Abstract: PURPOSE:To secure sufficiently measurement precision even if the front end surface of an optical fiber and a projection and recess part shift in relative position by slanting either of a projected and a recessed surfaces which are formed in a rotating body and decreasing the quantity of light incident on a photodetection fiber. CONSTITUTION:Projected and recessed surfaces 13 and 14 are formed in the peripheral direction of the rotating body 10 and a light transmitting optical fiber 11 which irradiates the projection recess surfaces 13 and 14 with light and the photodetecting optical fiber 12 which photodetects reflected light are provided successively. Recess surfaces 13 are slanted by an angle theta to right and left projection surfaces 14. Consequently, when the light transmitting fiber 11 and photodetecting fiber 12 face a slanted recess surface 13, the light from the light transmitting fiber 11 is reflected in a different direction from the irradiation direction, so the quantity of light incident on the photodetecting fiber 12 becomes a little. Therefore, the difference in the quantity of incident light between the recess and projection surfaces 13 and 14 becomes very large and the level difference does not vary greatly even when the axis of the rotating body 10 deviates or when the two optical fibers shift in arrangement position, so the measurement precision does not decrease.
