An amorphous alloy for a magnetic head has a composition which may be represented asCo.sub.100-T-X-Y-Z Re.sub.T Hf.sub.X B.sub.Y Si.sub.Z,where T, X, Y and Z satisfy the conditions of 0.2.ltoreq.T.ltoreq.1.5, 6.ltoreq.X.ltoreq.15, 3.ltoreq.Y.ltoreq.8 and 0.ltoreq.Z.ltoreq.0.01. Such an amorphous alloy has a high crystallization temperature, said temperature being higher than 500.degree. C., and does not lower the effective magnetic permeability, even if gradual cooling is performed after heat treatment. A magnetic head having a core consisting of such an amorphous alloy is not deteriorated in its magnetic properties, even if the head is made by glass bonding.
摘要:
In a powder supplying device, a powder container contains powder therein and is provided at a bottom of the powder container with a gas blowout part for ejecting gas to the inside of the powder container. A powder transport unit attracts powder contained in the powder container from a suction opening and transports the powder to a powder receiving device. A first detection unit is provided in the powder container to detect a remaining powder in the powder container.

Disclosed is a high-temperature solder material which is composed of tin, zinc and silver, or of 0.01 to 2 wt % germanium or aluminum and the balance tin, or tin and zinc at a ratio of 80/20 to 70/30. The tin/zinc/silver solder has a composition ratio that the ratio of till to zinc is within a range of 97/3 to 79/21 by weight, and the ratio of the sum of tin and zinc to silver is within a range of 88/12 to 50/50 by weight, or that the ratio of tin to zinc is within a range of 70/30 to 5/95 by weight, and the ratio of silver to the sum of tin, zinc and silver is 15% by weight or less. The solder material is used for producing electric or electronic devices and equipments.
摘要:
A heat-sensitive stencil including a porous support, and a thermoplastic resin film laminated on the support and having a surface smoothness of at least 10,000 seconds. The stencil is fabricated by bonding a thermoplastic resin film to a porous support with an adhesive having a specific viscosity and a specific volatile matter content, while maintaining each of the support and the film under a specific tension. The stencil may also be fabricated by applying a coating composition containing a resin and first and second solvents having a specific solubility and specific evaporation rates, and drying the applied composition to form a porous support. A printing master is produced by heating the above stencil imagewise by a thermal head with a heating energy of not greater than 0.05 mJ/dot.
