Title: Servo-signal writing method, magnetic disk device and magnetic disk
Inventor: SEO YOSUKE
IPC: G11B5/55
Filed: 1993-07-21
Abstract: PURPOSE:To prevent occurrence of phase deviation between tracks, and eccentricity of a disk by providing a clock signal on a magnetic disk, and performing reproduction of clocks and the recording of a servo signal with the same magnetic head. CONSTITUTION:A magnetic head 2 reprodcues an already recorded clock signal. The signal is amplified with an amplifier 8. A write-clock generating circuit 9 generates a recording clock for servo-pattern recording. A write-pattern generating circuit 11 generates a pattern, which is written into a magnetic disk 3, based on the recording clock outputted from the circuit 9 and the pattern outputted from a controller 12. The pattern is recorded on the magnetic disk 3 through a writing circuit 10. Then, the magnetic head 2 is sent by a head- position control mechanism 7, and the above described process is repeated. Here, the control mechanism also has the length measuring function when the magnetic head 2 is moved.

Filed: 1995-07-17
Abstract: PROBLEM TO BE SOLVED: To laminate optical fibers in parallel without crossing by arraying optical fibers, lead in a couple of gates at an interval a little larger than the diameter of the optical fibers, in a line and then putting them in contact with each other. SOLUTION: Many optical fibers 12 are arranged having their axes almost in parallel and led in couples of gates 18, 18' and 19, 19' at intervals a little larger than the diameter of the optical fiber 12, so that adjacent optical fibers 12 are arrayed in a line. The positions and order of the optical fibers corresponding to an incidence surface and a projection surface can be held accurately in 1:1 correspondence relation. Then adjacent optical fibers 12 are brought into contact from both the sides of the arrayed optical fibers 12 by contacting means 22, 22' and 23, 23', so such trouble that some optical fiber runs over other fibers is prevented and the optical fibers 12 can be brought into contact with each other while the correspondence relation is secured. Further, the optical fibers can be arrayed closely in the vertical direction.

IPC: G01C3/06
Filed: 1991-07-22
Abstract: PURPOSE:To improve the ranging precision of a sensor with the omnidirectional visual field at a long distance by specifying the convex mirror shape of a light receiving device. CONSTITUTION:In a light-applied distance sensor, the light emitted from a light source 1 is projected to an object to be measured 10 by a plane light projecting mirror 2 as the plane light 7, the reflected light 8 is guided to a two-dimensional light receiver 3 by a receiving convex mirror face 4, and a two-dimensional image is obtained here. The shape of the convex mirror face 4 is formed so that the distance from the point of the reflected light 8 on the object 10 to the vertex of the mirror face 4 and the distance between the sensor and the object 10 are kept at the proportional relation. The shape is obtained when the preset differential equation is solved, and the change of the distance on the image against the actual change of the distance, i.e., the resolution of the distance, can be unified. The reduction of the ranging precision at a long distance is prevented, and the uniform ranging precision can be obtained over the whole region in the effective range of the sensor.

Title: Water-base ink-jet recording fluid
Inventor: UEDA TAKAMASA
IPC: C09D11/033
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To obtain a water-base recording fluid which, unlike one prepd. by using a commonly used fungicide, is free from a safety problem with increasing toxicity by incorporating a specific dye as a fungicide into a water-base record ing fluid at least contg. a water-soluble dye and water.

Title: Stroboscope controller
Inventor: MITSU SHIGERU
IPC: G03B15/05
Filed: 1990-07-11
Abstract: PURPOSE:To perform soft light emission with appropriate light quantity without giving a strong stimulus to an object in the case of photographing the object which is sensitive to the stimulus of light by setting a low light quantity light emission mode and controlling the charge of a main capacitor based on the lowest light emission performable voltage of the main capacitor required for the light emission with the light quantity required for the illumination of the object. CONSTITUTION:A current which flows in a light emitting tube 4 during the light emission becomes maximum immediately after the light emission is started and the magnitude thereof is in proportion to a light emission start voltage and the intensity of emitted light becomes higher in proportion to the current which flows in the tube 4. Therefore, the soft light emission being low light quantity light emission is performed by setting the light emission start voltage to be low, so that the stroboscope emits the light with the lowest light quantity necessary for illuminating the object by stopping the boosting for the main capacitor 3 of a DC/DC converter 2 by a boosting action control means 22 when the voltage of the main capacitor 3 attains the lowest light emission performable voltage after starting charge. A lowest light emission performable voltage arithmetic means 17 acts only in the case of setting the soft light emission mode by a light emission mode setting means 16 and in the case of setting a macro mode by a macro mode setting means 15, outputs the lowest light emission performable voltage to the means 22 to control the boosting action of a booster circuit 2.
