摘要： PROBLEM TO BE SOLVED: To provide a method of fabricating metal particles for anisotropic conductive film, having high hardness, minimal contact failure uniform shape and usable as an alternative to the conventional conductive particles prepared by applying Au plating to resin particles, and the metal particles for anisotropic conductive film. SOLUTION: The method for fabricating the metal particles for anisotropic conductive film comprises steps of: forming a resinoid resist film on a substrate; providing micropores to the resist film; applying plating composed essentially of metal consisting of any of Ni, Cu, Ag and Au to the micropores; melting and removing the above resist; and peeling off the resultant metal plating particles composed essentially of metal consisting any of Ni, Cu, Ag and Au from the above substrate to obtain the metal particles for anisotropic conductive film.

摘要： PROBLEM TO BE SOLVED: To provide a method of manufacturing, in a large quantity, fine, uniform metal balls having high sphericity and uniform particle size distribution. SOLUTION: A minute crucible 1 is prepared by forming a plurality of minute holes in the (001) plane of a silicon wafer W and then applying burning in an oxidizing atmosphere to form SiO2 film on the inner surface. Subsequently, a film of metal to be formed into metal ball is formed on the inner surface of the minute crucible 1. Then, the wafer W is heated to bring the metallic film in the minute crucible 1 into a molten or semi-solid state, and the resultant metallic molten body is spheroidized by surface tension. By this method, a fine metal ball P is obtained.

摘要： PURPOSE:To simply, quantitatively evaluate fatigue strength by locally heating a boundary between the neck and the shaft of an engine valve to a highest temperature, and repeatedly applying a tensile stress until it is broken in the vicinity of the boundary. CONSTITUTION:For local heating means, a high-frequency induction heat having narrow heating range and easy temperature control is desirable. Since a heating position may be the vicinity of the boundary between the neck and the shaft of an engine valve for generating a fatigue destruction, a large-scale heater is eliminated. For a fatigue tester for applying a tensile stress, a tensile-tensile type in which a repetitive stress is applied to a test piece similarly to the stress loading state of an actual machine, is preferable. The piece is clamped by hydraulic clamping with a jig manufactured to match the actual valve shape. However, it is necessary to carefully consider the shape of the jig and the size of the high-frequency coil so that the jig is not excessively large to cause a high temperature. A thermocouple is mounted at a site of the highest temperature to measure the temperature, thereby, it is made possible to generate the fatigue crack and destruction at a highest temperature.
