Title: Light spot positioning method for optical disk device
Inventor: MASUNAGA YASUYUKI
IPC: G11B7/09
Filed: 1987-05-20
Abstract: PURPOSE:To improve the positioning precision by obtaining the quantity acting upon the control system of a main light spot as disturbance by inverse calculation in accordance with the spot position detection signal of a sublight spot and adding it to the driving signal of an actuator. CONSTITUTION:A sublight spot SPS preceding a main light spot SPM on the same track part is provided independently of the main light spot SPM which a main light beam for data read or write forms on the surface of an optical disk 1. A driving compensation signal X4 which equivalently cancels the disturbance (face wobbling of the disk and track eccentricity) applied to a control system 3 of the main spot SPM is obtained from a position detection signal X3 of the sublight spot SPS and is added to a control circuit output signal 3Ma of the main light spot. Thus, the positioning precision of the main light spots is improved.

Title: Three dimensional coordinate measuring apparatus
Inventor: WATANABE KEIICHI
IPC: G01B11/00
Filed: 1989-05-17
Abstract: PURPOSE:To measure a material to be measured stably by obtaining images when slit light is projected and when the slit light is not projected as the continuous images, obtaining the position of the slit light at the same time from the difference in images, and measuring the coordinates in real time. CONSTITUTION:Slit light (b) which is projected from a slit-light projecting means 1 is reflected from a material to be measured (a). The light is supplied into an image sensing means 2 as a light signal. An image memory 3 receives the first image outputted from the means 2, and the image is stored. When the second image is outputted from the means 2, the stored first image is outputted. In a differential image computing means 4, the second image outputted from the means 2 and the first image stored in the memory 3 are inputted at the same time, and the difference between both images is computed. Thus the differential images are outputted. The position of the image is computed in a slit-light position computing means 5 from the computed differential image. The three dimensional coordinates are computed in a coordinate computing means 6.

IPC: G01N27/82
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To reduce failure caused by a roll flaw in a magnetic flaw detection by providing a chrome layer on the surface of a stainless steel roll. SOLUTION: This roll for a steel sheet magnetizing device is used for a nonmagnetic hollow roll 4 of a magnetic flaw detection device. A chrome layer is provided on a surface of this stainless steel roll 4, and the roll 4 has extremely high hardness. Therefore, even if the steel sheet 1 is fractured while steel sheet 1 is made to pass and the fractured steel sheet 1 is brought in contact with the roll 4, a flaw is scarcely made in the surface of the roll 4, so that a waveform detected by a flaw detection head 2 can be prevented from being adversely affected. As for the chrome layer, for example, a chrome plating layer and a chrome roll can be listed. In the case of the chrome roll, a stainless steel roll is inserted in the chrome roll of a prescribed thickness, so that both are integrated by quenching fitting.

IPC: H01S3/0971
Filed: 1984-06-18
Abstract: PURPOSE:To enable the increase in output, prolongation in lifetime, and miniaturization of a discharge oscillator by a method wherein the cathode using a hollow cathode is flattened in cross section. CONSTITUTION:A cathode 18 is composed of the outer electrode 11 of cylindrical form opened on the side opposed to anodes 9 and the inner electrode 12 provided inside this outer electrode 11 by alienation from this electrode 11 and is formed into a member having the appearance of flat cross-section in the direction not to block flows of the excitation gas 8. This enables the generation of discharge between a slit 19 and the anodes 9 on the start of discharge. When a plasma 20 is thus generated in the slit 19, the plasma 20 creeps to the discharge space 13, and a current with a density several times that of a normal glow discharge current is led out of the hollow cathode 18 by the exhibition of hollow cathode effect, accordingly, the plasma 20 of high current-density is generated between the anode 9 and the hollow cathode 18. In other words, the laser output increases because of the increase in power density.

IPC: F23N5/10
Filed: 1987-05-21
Abstract: PURPOSE:To restrict amount of generation of oxygen nitride and keep a stable combustion state ranging from a high amount of combustion to a low amount of combustion by a method wherein a controller has a temperature sensing part for detecting a temperature of a burner cap through a thermocouple and an air ratio controller for controlling an amount of supplied air of a fuel supplying means or an air supplying means in such a way so that an output signal of the temperature sensing part becomes a constant value. CONSTITUTION:A thermocouple 13 is made such that a temperature measuring point 14 is closely contacted with a central position of a burner cap 15, connected to a controller 16 and an electromotive force generated at the temperature measuring contact point 14 is transmitted to a temperature detector part 17 of a controller 16. A temperature retrieving part 18 outputs a signal for varying an amount of combustion to an air ratio controller part 19 in such a way so that it becomes a constant value. An air ratio controller part 19 may control a pump 6 in response to an output signal of the temperature retrieving part 18 and adjust an amount of supplied fuel. The amount of supplied fuel is controlled in such a way so that the electromotive force shows a constant value and an air ratio is controlled to show any predetermined value (lambda=approximately 1.5). The air ratio is adjusted to keep a stable combustion condition, thereby a flame temperature when ignited is lowered and an amount of generation of NOx is reduced.

Abstract: PURPOSE: To obtain a superconductive wire of uniform and high electric current characteristics by beforehand applying preventing means for a mild metal squeezing on the end surface of an unworked composite material in subjecting a mild metallic bar and hard metals around the same to area reduction working to one piece.  
     CONSTITUTION: An Sn bar 3 is inserted into a composite pipe 4 formed of Nb wires 1 and Cu matrix 2, and the end face of the bar 3 is located to the central side from the end face of the pipe 4.
