Title: Control bar position detection unit
Inventor: NISHIZAWA YUKIO
IPC: G01D5/20
Filed: 1979-03-05
Abstract: PURPOSE: To compensate change of a relative permeability dependent upon temperature change of a drive axis to make it possible to measure the position of a control bar with a high precision, by providing a winding for temperature compensation on the drive axis of a magnetic material interlocked with the control bar.  
     CONSTITUTION: The inductive coupling rate of primary winding 2 and secondary winding 5 is changed by the insertion position of drive axis 1 between primary winding 2 and secondary winding 5, thereby generating an induced voltage corresponding to the insertion position of drive axis 1 in secondary winding 5. This induced voltage is subjected to full-wave rectification in 6 and is amplified in 9 after smoothing in 7 and 8. Control circuit 12 compares the induced voltage of temperature compensation winding 11 with reference voltage 13 and controls the gain of amplifier 9 by the output proportional to the difference between both voltages. Then, the gain of amplifier 9 is reduced and increased for temperature rise and temperature lowering of drive axis 1 respectively, thus outputting a voltage proportional to the position of drive axis 1 between coils 2 and 5 independently of temperature change of drive axis 1.

IPC: E02F9/22
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To reduce a cost by utilizing a sensor already arranged in a hydraulically driven machine, and also improve the operation characteristic of a lever by distributing a flow having a ratio according to the manipulated variable of each lever from a hydraulic pump to each hydraulic actuator without previously memorizing the pump maximum discharge flow even when the hydraulic pump is saturated. SOLUTION: A correction efficient α1 to correct the manipulated variable of a corresponding operating lever 6 (opening area A1 according to the manipulated variable) is calculated based on the real flow Qr1 detected by real flow detecting means 8a1 and a target flow Qm1 detected by target flow detecting means 8b1. The manipulated variable of the corresponding operating lever 6 (the opening area Al according to the manipulated variable) is corrected to A1' (=α1.A1) by using this correction coefficient α1.

Abstract: PURPOSE:To form a 2-stage P-type base layer by implanting aluminum and gallium by an ion implanting method by providing two layers of nitride films, depositing the aluminum on a boundary between the lower nitride film layer and a substrate and the gallium on an oxide film between the two nitride films, and covering the surface of the upper nitride film layer with the oxide film. CONSTITUTION:After aluminum ions 2 are implanted from the surface of a semiconductor substrate 1 to the substrate 1, the surface is sequentially covered with a first nitride film 3 and a first oxide film 4 at 500 deg.C or below. Then, after gallium ions 5 are implanted from the surface of the film 4, the film 4 is sequentially covered with a second nitride film 6 and a second oxide film 7 at 500 deg.C or below, it is annealed to diffuse the aluminum and gallium. Accordingly, the films 4, 6 prevent out-diffusion in the annealing step, the first and second oxide films 4, 7 prevent thermal stress from occurring due to the difference of the thermal expansion coefficients of the nitride and oxide films. Thus, 2-stage P-type base layer due to the aluminum and the gallium can be formed by the ion implanting method.
