Title: Optical pickup
Inventor: YUMA YOSHITO
IPC: G11B7/135
Filed: 1990-08-04
Abstract: PURPOSE:To prevent an adverse effect due to repeated diffraction by providing an optical device with size of 1/2 that of a lens pupil which diffracts reflected light from a disk in a tracking direction in the neighborhood of an objective lens to converge a laser beam from a laser beam source. CONSTITUTION:A diffraction grating 5 with size of 1/2 that of the pupil of the objective lens 6 and with the tracking direction in a diffracting direction is formed on a diffraction grating substrate 4. Incident laser beam from the laser beam source 1 is diffracted along the tracking direction on the disk 7, and around two sub beams generated by the diffraction are projected on positions before and behind a main beam in the tracking direction. In such a case, light transmitting a part where the diffraction grating with size less than around the half of the size of the objective lens 6 is provided is diffracted in the tracking direction, and is reflected on a disk plane. The reflected light transmits a part where no such diffraction grating is provided in the objective lens 6. Therefore, an error signal equivalent to the one by a three-beam system can be obtained.

Title: Optical switch of magnetic field variation type
Inventor: YATSUHASHI MOTOHARU
IPC: G01D5/26
Filed: 1987-08-21
Abstract: PURPOSE:To remove the effect of dust, water, oil, etc. by utilizing a Faraday element and a magnetized substance to detect the displacement of a displacement body to be detected, in a non-contact manner. CONSTITUTION:A light from a light source passes through an incident fiber 2a and enters a polarizer in a magnetic sensor 1 of a Faraday effect type to be polarized linearly. In the course of its passing through a Faraday element thereafter, the rotation of a polarization plane is given by an external magnetic field and this is converted into a change in the intensity of light by an analyzer. The light thus processed passes further through an emission fiber 2b and goes to a photodetector, and the intensity of light is detected therein. A C-shaped magnet (magnetized substance) 3 fitted to a displacement body to be detected which is in linkage to the displacement of a valve is disposed near said sensor 1. It comes near to and separates from the sensor 1 repeatedly in the direction of an arrow X with the displacement of the displacement body to be detected, varying the intensity of the external magnetic field impressed on the sensor 1. Accordingly, from the variation in the quantity of the emitted light from the analyzer due to the movement of the magnet 3 with the displacement of the displacement body to be detected, the photodetector computes the amount of movement of the displacement body to be detected and and detects the opening or closure of the valve.

IPC: G11B7/0045
Filed: 1985-09-19
Abstract: PURPOSE:To obtain a data write method for an optical recording medium with less mis-reading by splitting the entire storage area representing one bit of digital information, setting the optical state so as to bring each split part alternately to be optical high or low and expressing the state as a binary coding or the like. CONSTITUTION:Data write to an optical recording medium is applied by forming an optical change pattern along a track of an optical recording medium. The optical change pattern is formed by low/high reflectance and expressed by a write pattern, a white level and hatched lines, and the hatched part represents the low reflectance and the white level represents a high reflectance. The optical state is set in the track so that the entire storage area S representing one bit of digital information is either a high or a low level optically, and the state is used as the expression of '0' being one of a binary code. Further, the entire storage area S representing one bit of digital information is divided into three, the optical state is set so that each split part is in optically high or low level alternately and the state is used as the expression of '1' being other level of the binary code. Thus, the data write with less mis-reading is realized.

Abstract: PROBLEM TO BE SOLVED: To perform optimal steering during turning on a butt or work on a ridge or a line by increasing a hydraulic flow rate for steering a front wheel more than that for steering a rear wheel and changing a hydraulic flow rate in a steering mode. SOLUTION: For performing reverse-phase steering by a 4WS steering instructing switch, a hydraulic oil flow rate is increased by a flow rate control valve V5, and when a front wheel steering instructing switch is ON and front wheel steering is set, a flow rate is reduced by the flow rate control valve V5 by an amount equal to half of that during reverse-phase steering. For changing the ratio of a flow divider D without using the flow rate control valve V5 and increasing a flow rate for steering the front wheel more than that for rear wheel steering, in addition to the omission of the flow rate control valve V5, the dividing ratio of the flow divider D is set not to 1:1 but to front wheel : rear wheel = 2:1. Thus, during steering, the operation amount of the front wheel where a load is larger is reinforced.
