IPC: B23B27/14
Filed: 1990-02-09
Abstract: PURPOSE:To produce a laminated member coated with thin Ti-type film excellent in the adhesive strength of thin film by forming an intermediate Ti film of a specific thickness on the surface of a base material by an ion plating method and further forming a thin Ti-type film of Ti alloy, etc., on the above layer. CONSTITUTION:A thin Ti film of >=0.5mum thickness is formed on the surface of a base material by an ion plating method. Subsequently, a thin Ti-type film consisting of Ti alloy or Ti ceramics is formed by an ion plating method on the above thin Ti film as an intermediate layer. At this time, TiAl, TiNi, etc., can be used as the above Ti alloy, and further, TiN, TiC, etc., can be used as the above Ti ceramics. Moreover, it is desirable to carry out film formation while applying a negative voltage of about -400 to -1000V to the base material. By this method, the adhesive strength of the thin Ti-type film to the base material can be improved, and the laminated member coated with thin Ti-type film suitable for high hardness member, such as cutting tool, can be obtained.

Meanwhile, the gaps between measuring jigs 30, 32, 38, and 39 and a ribbon 44 are measured by the gage. With respect to a wing part 45 of the ribbon, the gap between the lower part of the wing part and the top part of a jig 26, under the state the wing 45 is opened, is measured if the gap is yielded. The gap between the upper end of the wing part and the tip part of a measuring jig 24, under the state the wing part 45 is closed, is measured by the gage in case the gap is generated.

Filed: 1986-02-10
Abstract: PURPOSE:To execute electrostatic painting of powder on a non-woven fabric by providing a counter electrode of a corona pin on a powder ejection gun under a nonconductive body such as the non-woven fabric. CONSTITUTION:Electric lines EF of force are generated by corona discharge between the corona pin 1 on a gun nozzle side and the corona pin 2 which is the counter electrode thereof. The powder is ejected in this state from the gun nozzle, then pulverized particle groups P thereof are attracted to the electric lines of force and rush toward the pin 2 by riding on the focused small-diameter electric lines EF of force, i.g., in the form of a small-diameter flux. The pulverized particle P groups of the powder accumulate and stick onto the fabric W or the like which is nonconductive and have the gas to allow the passage of the electric lines of force if said fabric W or the like is placed on the path where the groups pass. The fabric such as the non-woven fabric which is non- conductive and has the gaps is thus easily subjected to electrostatic coating.

Abstract: PROBLEM TO BE SOLVED: To recycle while dealing with digitizing of a printing step by providing a coating layer containing a compound decomposable by emitting a light having a wavelength of a higher energy than a band gap energy of a titanium oxide photocatalyst and a reducing action on a coat layer. SOLUTION: In the plate material for printing, a coat layer 3 containing a titanium oxide photocatalyst and a coating layer 4 formed on the layer 3 are formed on a surface of a base material 1 and a light having a wavelength of a higher energy than a band gap energy of the photocatalyst is emitted to its surface so that its hydrophobic property can be converted into its hydrophilic property. Accordingly, a hydrophobic part is used as a printing element part and a hydrophilic part is used as a non-printing element part, and hence a function as the plate material for printing can be performed. Thus, its recycling can be achieved by utilizing conversion properties from the hydrophobic property to the hydrophilic property, and an amount of the plate materials to be discarded after using can be reduced.
