    摘要： A wire member of cemented carbide based on tungsten carbide contains a binder phase of 4 to 35 % by weight of at least one metal selected from the group consisting of cobalt and nickel, 1 to 50 ppm by weight of unavoidable impurities and a hard dispersed phase of balance tungsten carbide. The tungsten carbide has an average particle size ranging from 0.2 to 1 µm. A particle size of the impurities is not larger than 10 µm. The distance between an axis of the wire member and a point on a periphery of the wire member disposed farthest from the axis of the wire member is 0.025 to 1 mm. The wire member may contain a binder phase of 15 to 35 % by weight of at least one metal selected from the group consisting of cobalt and nickel, 1 to 50 ppm by weight of unavoidable impurities, and a hard dispersed phase consisting of 0.1 to 40 % by weight of at least one compound selected from the group consisting of carbides of metals in Groups IV A , V A and VI A of the Periodic Table other than tungsten, nitrides of metals in Groups IV A and V A of the Periodic Table and solid solution of at least two of the carbides and nitrides, and balance tungsten carbide. The hard dispersed phase also has an average particle size of 0.2 to 1 µm.

    摘要： The temperature of the printing elements in a thermal printing head is controlled by controlling the electrical power supply to the thermal head, and thereby the amount of heat that is generated, said control also taking account of the different printing requirements of ordinary characters, bar codes, and so forth, data on the various such types of printing being stored in electronic memories for reference thereto for the said temperature control. The result is printing that is sharper and more uniform.
