Abstract: PURPOSE:To decrease the error factor of an output, and to obtain the linearity of the output by detecting a phase difference by a Sagnack effect by comparing a phase directly instead of an intensity of interference light. CONSTITUTION:The first optical beam which has been emitted from a light emitting device 1 is made incident on a polarized beam splitter 3, a P polarized light component travels straight, an S polarized light component is reflected and propagated in an optical fiber loop 6, led to the first frequency deviation element 8 (1) by an orthogonal polarization separating optical element 7a, subjected to + primary and - primary Bragg's diffractions, subjected to frequency deviations of +fAOM(1) and -fAOM(1), and also subjected to the - primary and + primary Bragg's diffractions and the frequency deviations of -fAOM(2) and +fAOM(2) in the second frequency deviation element 8 (2). Both linear polarized light beams are converted to circularly polarized light beams by using a polarizer 9, and the interference light of both the light beams is detected by a detector 11. A converted electrical signal 12 has a frequency of 2.¦fAOM(1)-fAOM(2)¦. A frequency deviation element driving device 15 outputs a signal 18 which is inputted to a signal processor together with the electrical signal 12 and is proportional to a phase difference between both the signals.

Title: Tactile sensor
Inventor: ISHIKAWA YOSHIKAZU
IPC: G01L1/04
Filed: 1994-03-18
Abstract: PURPOSE:To enhance response by a constitution wherein a resilient member imparts a constant force to a pressure sensor and a pressure receiving member receives a pressing force decreasing depending on the contact load with an object. CONSTITUTION:Three pressure sensors 4 are disposed at the vertexes of a right triangle on the ceiling face in a housing space 1b and a pressure receiving member 3 is urged in the direction opposite to a load by means of a plurality of resilient members, i.e., coil springs 5. The pressure receiving member 3 imparts, at the flange part 3b thereof, a constant pressing force to the sensor 4. The springs 5 are supported, at one ends thereof, by a base 6 which abuts, at the rear end thereof, on the forward end of a pressure regulating screw 7 driven from the outside of sensor housing 1. The base 6 is shifted by adjusting the screw 7 and pressing force of the spring 5 against the sensor 4 is regulated. When an object touches the member 3 to produce a load, pressing force of the spring 5 decreases depending on the load. Consequently, the force being applied to the member 3 can be detected based on the variation in the output from the sensor 4 which is thereby protected against fracture even if an undue pressure is applied to the member 3.

IPC: E02D23/08
Filed: 1979-04-23
Abstract: PURPOSE: To simplify and facilitate the sinking of caisson and reduce the cost for works by properly selecting the unit weight of concrete used for constructing each lot.  
     CONSTITUTION: At each stage of sinking of a caisson, the force of resistance against sinking to be expected for the next and the subsequent stages is calculated and then the necessary sinking load is computed, while the unit weight of the required reinforced concrete being computed as well.

In this way, it becomes unnecessary to add load such as an ingot or a sheet pile on every lot for accelerating the sinking as before, and also the works for improving the ground to prevent excessive sinking becomes unrequired.
