摘要： PURPOSE:To prevent the adhesion of the surface of a blank stock and the die inner surface by setting the surface roughness at more than specified value on the metal blank stock used for heading of forming the end part of the metal stock in specified shape by pressing it by a die in the axial direction or radial direction. CONSTITUTION:A metal material is of the Fe-Ni alloy contg. 33-55wt.% Ni and Fe-Ni-Co alloy, etc. The surface roughness of the metal stock is set in >=2mum at the max. height (R max) reference. The bar-like metal stock 2 cut in specified length is fixed by inserting to a die 1 and the head part 4 in specified shape is formed by compressing this metal stock 2 by pressurizing in the axial direction by a punch 3. At the time when the surface roughness of the metal stock is set in >=2mum, the lubrication function of a lubricant is maintained for long time. The seizure phenomenon of the die and metal stock is thus prevented effectively, the workability of the stock is improved and the die life can drastically to extended.

摘要： PURPOSE:To improve printing performance and reduce the size and cost by producing an iron alloy of a specific quantity of Cr as a base and the specific content of at least either one selected of Al, Si, Sc, Ti, V, Y, Zr, Nb, La and Hf. CONSTITUTION:A thermal head 1 consists of a driver substrate 3 and a resistor substrate 4 mounted and fixed on an aluminum radiation substrate 2. A drive IC 5 is mounted on the drive substrate 3 and a discrete lead 8 and a thermal resistor 10 are mounted on the resistor substrate 4. A high resistance base 11 of the resistor substrate 4 is composed of a metallic substrate 12 made or an iron alloy containing 5-30wt.% of Cr and 0.05-5wt.% of at least either one selected of Al, Si, Sc, Ti, V, Y, Zr, Nb, La and Hf and a high resistor layer 13 of a glass layer. Addition of Al, etc. contributes to the improvement of adhesion of the metallic substrate and the glass layer, and also to their corrosion inhibition. The above-mentioned constitution reduces the size and cost as well as improves printing performance.

摘要： PROBLEM TO BE SOLVED: To provide a method to produce a high quality negative for a shadow mask which can prevent difference of holes' diameter and shape during forming a punching holes matrix by an etching process and doesn't make any burn-out during an annealing process following the etching process. SOLUTION: Specified amount of ingredient metal is mixed and melted to be a requested composition. As a method to make a shadow mask of specified thickness from the casted metal, unevenness of a dull-roll's surface is transferred to negative's surface at the last rolling process.

摘要： PROBLEM TO BE SOLVED: To provide a stock for shadow mask, capable of producing an excellent shadow mask minimal in striped irregularity, composed of iron-nickel alloy or iron-nickel-cobalt alloy. SOLUTION: The desired iron-nickel alloy or iron-nickel-cobalt alloy composition is adjusted. This alloy is melted and pressed, and then hot rolling is performed to form a plate. Subsequently, the oxide layer, formed at the surface of the plate at the time of hot rolling, is removed uniformly without leaving remainings. The plate is cold-rolled and annealed, if necessary. Then, finish working is carried out. By this method, the stock for shadow mask can be obtained.

摘要： PURPOSE:To provide a shadow mask capable of restraining the occurrence of a color shear without impairing the advantage of a Fe-Ni alloy such as low temperature expansion and moldability. CONSTITUTION:A shadow mask is made of a Fe-Ni alloy material containing nickel at least within the range of 30 to 45wt.%. The alloy material has a surface layer containing Fe4N and/or Fe3NiN. Furthermore, only the surface layer of the alloy material is increased as Hv=170 or above. For example, when the surface layer hardness of the alloy material is H1 and the inside hardness is H2, a ratio of H1 to H2 is taken at 1.05 or above. According to this construction, a howling resistance characteristic can be improved.
