摘要： A method of manufacturing a semiconductor device comprising a ceramics cylinder, a metal seal member closing an open end of the cylinder, a semiconductor element located within the cylinder and having electrodes, and leads or electrodes connected to the electrodes of the semiconductor element and extending from the cylinder. The method comprises the steps of coating powder of active metal consisting of Ti and/or Zr on the end face of the ceramics cylinder without heating the ceramics cylinder, in an amount of 0.1 mg/cm.sup.2 to 10 mg/cm.sup.2, mounting a layer of brazing filler metal on the end face of the ceramics cylinder, which have been coated with the powder of the active metal, placing the metal seal member on the layer of brazing filler metal, and heating the ceramics cylinder, the metal seal member, and the layer of brazing filler metal, thereby melting the layer of brazing filler metal and, thus, brazing the metal seal member to the open end of the ceramics cylinder.

摘要： {W—CuxSb-balance Cu} alloy is employed for contacts. As the anti-arcing constituent in the alloy W or WMo in a content of 65 to 85%, of grain diameter 0.4 to 9 &mgr;m is employed. As auxiliary constituent, CuxSb is employed, the content of the CuxSb being 0.09 to 1.4 weight %, the x being x=1.9 to 5.5, the grain diameter being 0.02 to 20 &mgr;m, and the mean distance between grains being 0.2 to 300 &mgr;m. As conductive constituent, Cu or CuSb solid solution is employed, the Sb content present in solid solution form in the CuSb solid solution being less than 0.5%. As a result, not only is dispersion of CuxSb, which is evaporated on subjection to arcing, reduced, but also generation of severe cracks, which have an adverse effect in terms of occurrence of restriking. Arcing at the contacts surfaces is prevented, suppressing dispersion and exfoliation of W grains. In this way, damage due to melting and dispersion at the contacts surfaces is reduced, enabling both restriking to be prevented and the contact resistance characteristic to be improved.
摘要翻译： {W-CuxSb-余量Cu}合金用于接触。由于合金W或WMo中抗弧成分含量为65〜85％，粒径为0.4〜9μm。作为辅助成分，使用CuxSb，CuxSb的含量为0.09〜1.4重量％，x为x = 1.9〜5.5，粒径为0.02〜20μm，晶粒间的平均距离为0.2〜300μm。作为导电成分，使用Cu或CuSb固溶体，CuSb固溶体中以固溶体形式存在的Sb含量小于0.5％。结果是，不仅在电弧放电时蒸发的CuxSb的分散减少，而且产生严重的裂纹，这在再起弧的发生方面具有不利的影响。防止了在接触表面的电弧，抑制了W晶粒的分散和剥落。以这种方式，由于触点表面的熔化和分散而导致的损坏减少，从而能够防止再起弧，并且提高接触电阻特性。

摘要： In a closing magnetic circuit, when a movable contact is in contact with a fixed contact and a switching device is closed, N and S poles of a permanent magnet attract the fixed member in a direction in which the movable contact is pressed against the fixed contact. In an opening magnetic circuit, when the movable contact is separated from the fixed contact and the switching device is open, one of the N and S poles of the permanent magnet attracts the fixed member in a direction in which the movable contact is separated from the fixed contact. An operating electromagnet winding increases and decreases the magnetism in the closing magnetic circuit and opening magnetic circuit. With this configuration, it is possible to realize an operating apparatus for a switching device using a simple mechanism and assure a stable operation by producing a great contact load.
