Title: Device for detecting position of linear actuator
Inventor: NAKAISHI TAKAMICHI
IPC: G01B7/00
Filed: 1994-04-20
Abstract: PURPOSE:To improve the resolution of a device for measuring position of linear actuator by providing a recessed and projected section which revolves along the outer peripheral surface of a nut and is formed on part of the outer circumferential surface of the nut and a position detecting means which outputs a signal in accordance with the position of a mobile section engaged with the recessed and projected section. CONSTITUTION:A thread 44b is formed on the outer circumferential surface of a lock nut 44 and the nut 44 is fixed to the outer circumference of a nut 41 with screws 44a and 44f. A potentiometer is set above the nut 44 and the front end of the mobile section 51a of the potentiometer is engaged with a screw 44b on the outer circumferential surface of the nut 44. In addition, the potentiometer is fixed to a bearing member 15 so that the mobile section 51a of the potentiometer can freely slide linearly in its axial direction. When the nut 41 is rotated by means of an electric motor, the shaft of an actuator moves in its axial direction and, at the same time, the mobile section 51a of the potentiometer engaged with the screw 44b moves in its axial direction. As the result, the potentiometer outputs a signal indicating the position of the shaft of the actuator.

Filed: 1983-05-12
Abstract: PURPOSE:To prevent a prime mover from over-run due to a motor action of a variable pump in descend along a steep slope by increasing a pressure in a hydraulic pump circuit when the rotational frequency of the prime mover exceeds a set governor range by a throttle lever. CONSTITUTION:When an engine is in a limit point of controlling the rotational frequency increased by a motor action of a variable capacity type pump and the output characteristics of a function generator 11b is set such that the out-signal of the function generator 11b has a maximum value, the engine is driven by the motor action of the hydraulic pump. When the rotational frequency of the engine reaches point B', the out-signal more than zero is generated from the function generator 11b. The signal is amplified by an amplifier 11c to drive an electromagnetic proportion relief valve 8 for increasing the circuit pressure in a fixed type hydraulic pump. When the circuit pressure is increased, load on the hydraulic pump is increased and applied to the engine so that the increase of rotational frequency of the engine is restrained. Also, when the rotational frequency exceeds point B' the corresponding out-signal is increased so that the load on the hydraulic pump is increased to prevent the engine from over-run.

Abstract: PURPOSE:To obtain a device of simple constitution which has small parallax among respective photodetecting elements and high photodetection efficiency by providing a diffraction grating to a transparent optical member which guides light to a wavelength selecting member for selecting the wavelength of the light incident on the individual photodetecting elements. CONSTITUTION:The photodetecting elements 11-13 where color filters 14-16 having wavelength selectivity are stuck detect the R, G, and B components of incident luminous flux respectively. Then the transparent optical member 17 is arranged in front of the elements 11-13 and the diffraction grating 18 consisting of grating grooves, etc., is provided thereupon to scatter and project the incident luminous flux in the array direction of the elements 11-13. Here, when the array direction of the elements 11-13 is coincident with the Y axis of a three-dimensional coordinate system, the X axis is in the traveling direction of light from a subject and the grating grooves of the grating 18 are arranged in parallel to the Z axis and periodically, e.g. at equal intervals in the Y-axial direction. Then when light from an illumination light source is projected on a subject, its reflected light is scattered by the grating 18 intensely in the array direction of the elements 11-13 and incident equally on the elements 11-13. Thus, the parallax among the elements 11-13 is reduced and the influence of the color pattern of the subject is minimized.
