摘要： PURPOSE:To make the level of leakage magnetic flux quantity detected by a read detector uniform and to improve information reading accuracy by detecting magnetic fluxes at positions different from each other near a magnetizer and controlling the magnetizer so that the level of magnetization in the write area of a base material may be made uniform. CONSTITUTION:In an information reader 4 for reading information bit 3 written in a steel plate 2, the level of magnetization of the steel plate 2 is made uniform so as to improve the reading accuracy. Namely, a winding 6 constituting the magnetizer 7 is divided into two windings 6A and 6B and controlled with a current supplied from a control part 9. A Hall element 10 functioning as a magnetization detector is arranged near both ends of the electromagnetic core 5 of the magnetizer 7 and controls a current from the control part 9 so as to make the outputs of both Hall elements 10 equal. Thus, the level of the magnetization of the steel plate 2 is made uniform over all the area in an information write area. As a result, the levels of the outputs of the respective Hall elements 8 are made uniform, information bit is accurately discriminated and the reading accuracy is improved.

摘要： PURPOSE:To execute satisfactory beam machining of the quality being free from a melted and resolidified layer and a burr by irradiating a work by an energy beam in an atmosphere in which the degree of vacuum is the degree of vacuum or above by which a component contained in said work shows a sublimation property. CONSTITUTION:A laser beam 2 from a laser oscillator 1 is condensed to the working surface 15 of a work 14 by a condensing lens 3, the working surface 15 is melted and evaporated by its high density energy and a hole 18 is pierced. In the beam machining the work 14 is placed in a vacuum chamber 10, and is irradiated with the laser beam through a laser beam take-in use window 11. Also, the inside of the vacuum chamber 10 is filled with an atmosphere in which the degree of vacuum is raised to the degree of vacuum or above by which a component contained in the work 14 shows a sublimation property. As a result, by irradiating the laser beam 2, the component is sublimated and high pressure is generated in the inside of an irradiated area. By its pressure, an adjacent molten area and a bulk-like part are scattered, and a worked hole 18 being free from a melted and resolidified layer and a burr is obtained.

摘要： PURPOSE:To enable use in a high temp. range by heating austenitic stainless steel contg. ferrite precipitated by rolling at prescribed intervals and converting the heated parts into nonmagnetic parts. CONSTITUTION:Ferrite is precipitated in the surface layer of austenitic stainless steel 1 by applying force such as rolling force to render magnetism. The steel 1 is then heated at prescribed intervals, e.g., with laser beams 3 to cause transformation into the original austenite structure and the heated parts 3 are converted into nonmagnetic parts.

摘要： PURPOSE:To improve the quality of a cut surface by moving the irradiation point of a laser beam, cutting a work and further irradiating the entire part or a part of the cutting route thereof with the laser beam. CONSTITUTION:The optical path of the laser beam 2 is disposed therein with 1st, 2nd partial reflecting mirrors 3a, 3b in series. The inclination angle of the reflecting mirror 3a is set at 45 deg. and the inclination angle of the reflecting mirror 3b is set at 45 deg.+alpha. The work 6 is first irradiated with the 1st laser beam 2a and is thereby cut. The 2nd laser beam 2b is then made incident to a condenser lens 4 via the partial reflecting mirror 3b and the entire part of a part of the cut surface is irradiated with this beam. An assist gas is ejected from a nozzle hole 5 at this time. Since the cutting route is irradiated again with the laser beam 2b, the aggregate sticking to the cut surface is surely removed. The quality of the cut surface is, therefore, improved.

摘要： PURPOSE:To adjust the amt. of vaporized particles and to form a multi element film having a desired composition by using plural kinds of materials to be irradiated at the time of forming an oxide film by laser vacuum deposition. CONSTITUTION:A vacuum chamber 5 is evacuated to a specified vacuum, and then O2 is introduced into the chamber 5 to form an atmosphere at a specified pressure. The first material 7a to be irradiated consisting of a mixture of a copper oxide and a Ba salt(BaCO3) in 3/2 molar ratio and second material 7b of a Y oxide previously formed and set in the chamber 5 are respectively irradiated by the condensed laser beams 1a and 1b, and vaporized. The respective kinds of vaporized particles are simultaneously deposited on a substrate 8, and a multi element film of the deposited plural kinds of vaporized particles is formed. Since the amts. of the respective kinds of vaporized particles can be adjusted by this method, an oxide film having a desired composition is obtained.
