Title: Correcting method of output value of bridge circuit
Inventor: SHIMIZU TAKU
IPC: G01B7/16
Filed: 1990-03-07
Abstract: PURPOSE:To correct an output value of a bridge circuit without physically breaking a resistance body by cutting the correction resistance body through electrolytic corrosion. CONSTITUTION:An insulating layer 3 is formed on a metallic or glass substrate 2, onto which strain gauge resistance bodies R1, R2, R3, R4 and correction resistance bodies r1, r2, r3, r4 of amorphous metal are layered, whereby a sensing part 1 is formed. A bridge circuit is constituted by connecting each resistance body and each correction resistance body with electrodes 4, 5, 6, 7, 8. An error of a resistance value is detected by impressing a predetermined voltage to the circuit, and a correction resistance body to be cut is selected. For instance, if the correction resistance body r1 is selected, after a drop of water 9 is dropped onto the correction resistance body r1, and probe pins 11 and 12 are respectively brought into contact with the water drop 9 and electrode 4, a predetermined voltage is impressed to cause electrolytic corrosion to the correction resistance body r. Therefore, the circuit simulates the state of being cut. After making corrections, the sensing part 1 is cleaned and subjected to moisture-proof coating. Accordingly, the resistance value of the circuit can be corrected without a cutting process.

Title: Interference intensity detection method for interferometer
Inventor: YAMAHA TSUNEO
IPC: G01B9/02
Filed: 1998-02-20
Abstract: PROBLEM TO BE SOLVED: To exactly measure the phase difference corresponding to the distance between a level difference or the height of a projection, by splitting a first and a second laser light with a splitting means, operating the reception light output of one of the laser lights and the reception light output after polarizing the other laser light, and outputting a signal corresponding to the phase difference between both of measuring/ reference beams. SOLUTION: Both of the laser light split in a half mirror 11 and reflected or transmitted in a polarization beam splitter 12 go in a photosensor 13 and 14, respectively. An addition amplifier 17 adds the signals from a sensor amplifiers 15 and 16 and an operator 1C multiplies the signals from the sensor amplifiers 15 and 16 and outputs a root output to an operator 1D. On the other hand, the interference wave of laser light having passed the half mirror 11 and introduced in a polarization plate 18 goes in a photosensor 19. A subtraction amplifier 1B subtracts the slice voltage of the addition amplifier 17 from the interference output of a sensor amplifier 1A and outputs it to the operator 1D.  The operator 1D divides the output of the subtraction amplifier 1B by the output of the operator 1C, so that its output signal becomes output waveform depending only on the phase difference without being affected by the reflectivity.
