摘要： PROBLEM TO BE SOLVED: To improve the adhesion between a board and circuits and simplify the process to reduce the production cost by hot pressing Cu foils preformed in desired solid shape and required number of prepreg sheets into a unified board by solid dies. SOLUTION: Cu foils 2 are preformed by forming dies 3 and set in a lower die 32, prepreg sheets 11 are laid on the preformed foils, and hot pressed through on upper and lower dies 31, 32 to form a board, and the foils 21 are etched to form circuit patterns by the known method, to finish a Z-shaped microwave circuit board 4. For a both-side board, two preformed Cu foils 21 are set between an upper and lower dies and prepreg sheets are inserted therebetween. For multilayer board, double-sides boards are prepared, prepreg sheets are inserted between the double-sided boards and above steps are repeated.

摘要： PURPOSE:To provide an electrode for a distributor, which is excellent in the noise wave preventing effect, has stability during a long period of time, is improved in reliability and is suitable for mass-production by providing an electric conductor on the surface portion of a high resistance material layer. CONSTITUTION:A silicon nitride film about 3mum as a high resistance material layer 4 is formed on the surface of a brass rotor electrode 1 by laser PVD method using CO2 laser. Further, tin oxide as an electric conductor 5 is formed in such a manner as to coat about 10% of the surface area of a high resistance material layer 4 by the same laser PVD method. Whereupon, as the formed high resistance material layer 4 is a very close film and has high adhesive force, and adhesive force of the conductor 5 is high, separation or defect of the high resistance material layer 4 and the dielectric conductor 5 is hardly caused and the durability is improved. Accordingly, long-time stability of a noise wave preventing effect is ensured, and furthermore, the high resistance material layer 4 and the electric conductor 5 can be continuously formed in a comparatively short time so as to be excellent in productivity.

摘要： PURPOSE:To enable mass producing with good workability highly reliable flat platelike heating elements resistant to a thermal shock extending over a long period of time, by spray coating and accumulating ceramic on the metal shaped into a heating electrode placed on a ceramic base and by holding and fixing said metal between both ceramics. CONSTITUTION:A tungsten foil rapped into a desired shape of heating electrode 1 is temporarily fixed on an alumina single crystal base 2 by adhesive so as to be placed on said base, alumina is accumulated and stuck through plasma spray coating to form an alumina layer 3, and said tungsten foil is held and fixed between the alumina single crystal base 2 and alumina layer 3 so that a flat platelike heating element is obtained. Accordingly, the production time of said element is as short as about one minute and the number of manufacturing processes also decreases to enable the mass production of the heating element. Further, because a tungsten foil is used as the heating electrode 1 for said flat platelike heating element, the element thus manufactured is higher in denseness and less in stress than a vapor deposited film. Therefore, said element causes neither breaking of wire nor crack and can exhibit an excellent thermal shock resistance.

摘要： PURPOSE:To easily make ceramic coating of high quality on a cylindrical inside surface by irradiating a spectrally divided laser beam to the pyramidal end face of a rotating ceramic member inserted into a cylindrical work moving in an axial direction. CONSTITUTION:The cylindrical work 7 is set in a vacuum vessel 5 in such a manner that said work can be axially moved by a gear 22 engaged with a tooth part 21a at the end face of a table 21 supporting the work when said gear is rotated by a motor 23. The ceramic member 13 of which the end is formed to the pyramidal end face is inserted into such work 7 and is rotated in an arrow (n) direction by a motor 20. The laser beam 2 from a laser oscillator 1 is spectrally divided by a wedge-shaped spectral mirror 17, an annular condenser mirror 18 and a window lens 6 and is irradiated to the pyramidal end face 13a. The ceramics is heated by the irradiated laser beam 2 and the formed evaporating particles 14 are made to collide perpendicularly against the inside peripheral face 7a of the work 7 by which the ceramic coating having the good adhesiveness is uniformly formed over the entire surface thereof.

摘要： PURPOSE:To form a ceramic film of a uniform thickness on the inside of a tubular material to be coated by using a ceramic member in the form of a rotatable column having an outside diameter smaller than the inside diameter of the material to be treated and by irradiating laser beams on a prescribed position of the sloped end of the member. CONSTITUTION:One end 13a of a rotatable columnar ceramic member 13 having an outside diameter smaller than the inside diameter of a tubular material 7 to be coated is sloped with respect to the direction of the axis of rotation. In a vacuum vessel 5, laser beams 2 are converged and irradiated on a position of the sloped end 13a at a prescribed distance from the center of rotation. Ceramic particles 14 are evaporated by the irradiation to coat the inside of the tubular material 7.
