摘要： PURPOSE:To enhance detection sensitivity and an S/N ratio by heating non- magnetic austenite type stainless steel at a desired interval by a high energy density heat source while a magnetic field is applied to said steel. CONSTITUTION:A current is supplied from a DC power supply 22 to form magnetic flux 30 and this magnetic field is applied to a base body composed of non-magnetic austenite type stainless steel. Laser beam 20 being a high energy density heat source is applied to said base body 1 so as to form a desired interval between heated parts 3 to heat and melt the same while the molten parts are solidified to form magnetic grids of a predetermined interval. About several % of magnetic ferrite is precipited in the austenite texture of each molten/ solidified heated part 3. Since a magnetic field is applied during the irradiation with laser beam, the axis of the precipitated ferrite magnetic body is aligned in a definite direction to generate magnetic anisotropy. Therefore, the interval between the magnetic grids is arbitrarily selected and a Hall element detecting residual magnetization quantity is used to obtain the relation between displacement quantity and residual magnetization quantity. By this method, displacement can be detected.

摘要： PURPOSE:To improve the heat resistance, the flame resistance, the strength and the electric insulating property by means of an insulation substrate in which the mixture of a specified inorganic powder and a thermosetting resin powder is combined with an inorganic fiber or a mica. CONSTITUTION:The mixture of an inorganic powder comprising an orthoboronic acid and a oxide or a calcium oxide and a thermosetting resin powder is combined with an inorganic fiber or a mica to make an insulation substrate. The substrate is inserted between the dies heated beforehand to be pressurized by heat. In this process, gas breathing is made at least once. Then, in the final stage of the treatment, it is cooled and the insulation molding is treated by heating. For the inorganic fiber, ideal are glass fiber and asbestos fiber. For the powder mixture, ideal is a blending of the orthoboronic acid 100wt% with the zinc oxide 5-150wt% and a thermosetting resin powder 8.2-62.5wt%.

摘要： PROBLEM TO BE SOLVED: To rapidly and accurately form a through-hole, etc., in a printed board which contains cloth-like glass fiber by casting laser beam on a processing part of a wiring board in pulse for a specified beam irradiation time and energy density. SOLUTION: Three double-sided copper clad glass epoxy printed boards are used as a multilayered printed board 1A. The copper foil of conductor layers 2, 3, 4 is 18μm thick and a copper foil removal part 8 of a diameter of 200μm is formed by etching. Laser beam 27 whose light source is a carbon dioxide gas laser is cast on a processing part of a wiring board in pulse for a beam irradiation time in the range of 10 to 200μs and energy density of 10J/cm or more. Laser beam is cast on the same processing part of a wiring board at a beam irradiation quiescent time interval of 15ms or more and energy density of 20J/cm or more as pulse.

摘要： PURPOSE:To improve reading accuracy even in a high temperature environment by changing the magnetic characteristics of a part of a substrate of a magnetic marker with a prescribed interval by beam irradiation to magnetically write information and reading out the information of the substrate by a heat-resisting magnetic sensor constituted of a heat-resisting exciting source and a heat- resisting magnetic detection part. CONSTITUTION:The magnetic sensor 3 constituted of the exciting source and the magnetic detection part is a permanent magnet having >=200 deg.C Curie point. Since the substrate 1 is made of stainless steel in an austenite group, ferrite structure is deposited and magnetism is generated by irradiating the substrate 1 with laser beams projected from a high energy density heat source and fusing a part of the substrate 1, so that the deposited part is utilized as an information element 2. The obtained magnetic marker has >=100 deg.C Curie point and heat- resisting characteristic. The heat-resisting magnetic sensor 3 is moved on the information element part of the marker. Thus, information can be highly accurately read out even in >=100 deg.C environment.

摘要： PURPOSE:To enhance detection sensitivity and an S/N ratio by superposing non-magnetic austenite type stainless steel on ferromagnetic steel and heating both of them at a desired interval on the side of the austenite type stainless steel using a high energy density heat source. CONSTITUTION:A base plate 1 is constituted by superposing plate-shaped non- magnetic austenite type stainless steel 2 on plate-shaped ferromagnetic steel 1. Laser beam or electron beam 20 being a high energy density heat source is applied to the heated parts 3 of the base plate 1 so as to form a desired interval between the heated parts 3 to heat the same and at least a part of the non-magnetic steel and the ferromagnetic steel 1 is melted at the heated parts 3 to be solidified. The non-magnetic steel 2 is melted by the irradiation with laser beam to be mixed with the ferromagnetic steel 1 and subsequently solidified to form magnetic grids to the base plate 11 at a predetermined interval. By irradiating the base plate 1 with beam to arbitrarily select the interval between the magnetic grids formed on the substrate 1 and using a magnet 4 and an element for detecting the quantity of magnetic flux 30, for example, a Hall element, the relation between displacement quantity and residual magnetization quantity is obtained and displacement can be detected.

摘要： PURPOSE:To reduce cost by forming a free carbon film on the rear of a work such as a stainless steel and irradiating a laser beam thereto thereby cutting the work simultaneously together with the free carbon film. CONSTITUTION:The laser beam 1 is bent perpendicularly by a total reflecting mirror 3 in the 1st cylindrical body 2 and is then condensed by a condenser lens 5. The condensed beam is irradiated to a horizontally disposed work 6. The free carbon film 10 is formed on the rear of the work 6 by a paint contg. carbon and therefore the work 6 is simultaneously cut together with the film 10 by the beam 1. The molten metal cannot stick to the bottom edge in the cut part by the presence of the film 10 in this state. The generation of a sagging part is thereby prevented and therefore the need for cutting such part is eliminated and the cost for cutting is reduced.
摘要翻译：目的：通过在诸如不锈钢的工件的后部形成游离碳膜并照射激光束来降低成本，从而与游离碳膜同时切割工件。构成：激光束1在第一圆柱体2中被全反射镜3垂直弯曲，然后被聚光透镜5冷凝。聚光束被照射到水平布置的工件6上。形成游离碳膜10 在工作的后方6由油漆contg。碳，因此工件6与薄膜10同时被梁1切割。熔融金属在这种状态下不能通过薄膜10的存在而粘在切割部分的底部边缘上。由此防止了下垂部分的产生，因此不需要切割这种部件，并且减少了切割成本。
