摘要： PURPOSE:To stably form a vapor-deposited film for a long period with good efficiency in laser light irradiation at the time of irradiating a film forming material with laser light in a vacuum vessel to form the vapor-deposited film on a substrate by using a film forming material container of specified shape and blowing a gas against the inner surface of a laser light-transmitting window to clean the inner surface. CONSTITUTION:The vacuum vessel 1 is evacuated, and a supporting shaft 2 is rotated to rotate a holder 3 and plural substrates 22 thereon. The substrate 22 on the holder is electrically heated by a power source 10, gaseous Ar, etc., from a cylinder 17 are blown against the inside of the laser light-transmitting window 14 to clean off the deposited film forming material and to keep the transmissivity of laser light, the film forming material 23 in the container 4 on the holder is irradiated with the laser light 24 from a laser oscillator 12 through the window 14, hence the material 23 is heated and vaporized, a glow discharge is generated between an electrode 19 and the holder 3, and the vapor of the material is activated by the ionized Ar and attracted on the substrate 22 by the voltage gradient between the holder 3 and the electrode 19 to form a film. Since the container 4 is conical with the upper part narrowed, the laser light 24 is repeatedly reflected in the container, hence the material 23 is efficiently heated, the material is not leaked to the outside, and the instruments in the vacuum vessel are not damaged.

摘要： PURPOSE:To obtain a die having a long service life by projecting laser rays to a steel plate stock, heat treating and cutting it and forming another hard faced layer on the blade part of the die. CONSTITUTION:A contour part of the die 9 is irradiated by CO2 laser rays as shown by an arrow L. The steel part stock 8, in this case, is of flame hardened steel. When the laser rays are projected by the focal isolation system in this way, the laser rays can be projected over the prescribed area. When the contour part of the component for a die blade part is hardened, a 1st hard faced layer 10 having a circular arcuate section is formed from the surface of the steel plate stock 8 in the thickness direction. Then, the focally isolated laser rays are projected to a position adjacent to the inside of the contour part of the die 9 to form a 2nd hard faced layer 11. Then, the laser rays are projected in a focal state to cut the steel plate. The cut part is located in the center of the 1st hard faced layer 10. The die 9 manufactured in this way is used to manufacture a press die in a knockout system.

摘要： PURPOSE:To simplify manufacturing processes without impairing characteristics by placing on the base a mixture of different types of powder containing elements from which a compound superconductive substance of oxide type can be composed, forming therefrom a mixture layer, irradiating laser beam thereupon, and converting it into a compound superconductive layer of oxide type. CONSTITUTION:A mixture of different types of powder containing elements, from which a compound superconductive substance of oxide type can be composed, is placed on the base 2 of metal to form a mixture layer 3. Then laser beam 4 is irradiated onto this mixture layer 3 to melt and solidify one after another, and thereby the layer 3 is converted into a compound superconductive substance layer of oxide type, which is held consolidated with the base 2. This provides manufacture of long compound superconductive wires having great critical amperage and high critical temp. characteristic peculiar to compound superconductive substance of oxide type, that does not require any complicated processes, and also the cost will be suppressed to a great extent.

摘要： PURPOSE:To prevent change in the oscillation mode and intensity of laser light and to lessen the deterioration of an optical system disposed in the transmission path thereof by forming a light transmission body for guiding the laser light oscillated from a laser oscillator to hermetic structure capable of reducing the pressure thereon and reducing the pressure in said body. CONSTITUTION:The laser oscillator, the light transmission body which guides the laser light released from the laser oscillator and is formed into the hermetic structure capable of reducing the pressure therein, and a pressure reducing device which reduces the pressure in this light transmission body are provided. The attenuation of the laser light during transmission can be lessened if the light transmission body for guiding the laser light oscillated from the laser oscillator is made into the hermetic structure capable of reducing the pressure therein and is used after the pressure therein is reduced. The change in the mode to be generated by multiple reflections of fluctuation of gas or the like is prevented and the deterioration of the optical system is prevented by disposing said system in this light transmission body.
