Title: Eddy current check unit
Inventor: WATANABE SEIICHI
IPC: G01N27/90
Filed: 1979-07-09
Abstract: PURPOSE: To make it possible that the response speed for switching is high, by using a semiconductor variable resistance element such as the field effect transistor for the input signal circuit to the adding circuit in the circuit which cancels the output of an eddy current detector.  
     CONSTITUTION: A part of output voltage of phase detecting circuits 4 and 4' is input to bias adjusting and output amplifiers 305 and 305', and another part is input to similar amplifiers 306 and 306' after inverting the polarity of output voltages. In case that a detection output appears from eddy current detector 2, output voltages of bias adjusting and output amplifiers 305 and 306 and similar amplifiers 305' and 306' are changed to voltages of directions opposite to each other respectively with fixed bias voltages as the center, and these output voltages are applied to  gates G of FET307, 308, 307' and 308' respectivey, and therefore, output voltages  at connection points between FET307, 308 and between FET307' and 308' are  changed. Cancelling circuit 30 functions by inputting these output voltages to adding circuit 301. The response speed for switching can be high by constituting the  cancelling circuit electronically purely in this manner.

When the temperature sensor is connected to a three-wire bridge circuit through the terminals 6, 6', a resistance Rx of the resistance body constituted of the slit pattern 4 is obtained. Then, the temperature (t) of a main scale 1 is obtained from the related formulae. Therefore, the amount of the linear expansion is calculated from the coefficient of the linear expansion of a glass base of the main scale 1 and the temperature change of the main scale 1. An error of the measuring value because of the thermal deformation can be immediately corrected.

Filed: 1978-07-18
Abstract: PURPOSE:To obtain the high yield through the realization of high integrated density by providing the thin insulation film between two polycrystal Si films or between the polycrystal Si film and metal film to form the memory cell. CONSTITUTION:On an insulation film 20 is selectively coated polycrystal Si film 26, in which an area 27 with the diffused impurities is formed. Then, on the film 26 also selectively coated is an insulation film 20' having different depth, on which a polycrystal Si film or metal film 28 is selectively formed. The portion of the polycrystal Si film with no diffused impurities serves as the insulator. Cross points of the area 27 and the film 28, that is dotted circle areas 100, give memory cells and the depth of the film 20' is formed to be thinner at the parts corresponding to the areas 100. Thus, the area of the memory cell becomes equal to that of the area 100 and then no need for making an additional insulation area enables the significant reduction in the area used, which is essential to realize the high integration. It can be also expected to obtain the high yied because of the less numbers of junctions to be formed.
