摘要： PURPOSE:To realize positive contact by providing a contact portion connected to a minus potential side inside a substrate and, forming a chevron-shaped protrusion at a confronting position to a fixed contact of a metallic casing and on a contact plate of a conductive leaf spring which is pressed when said substrate is inserted. CONSTITUTION:A hole 8c as well as a bracket is formed at a middle portion of a contact plate 8 made of phosphor bronze plate. The contact plate 8 is mounted in a gas meter casing through the hole 8c. A contact portion 8a at an upper end of the contact plate 8 has a chevron-shaped protruding contact point 8e. An end of the contact point 8e is depressed against a contact point 6 of a substrate 9 by the contact portion 8a because the contact portion 8a is deflected when the substrate 9 is inserted into the bracket assembled with the contact plate 8, and accordingly the contact plate 8 can be in positive contact with the substrate whether the surface of the contact portion 8a is attached with dusts or covered with an oxide film.

摘要： PURPOSE:To mitigate a thermal stress, generated in a torque tube upon cooling, and maintain the reliability of a structure, by a method wherein the torque tube is fixed to a coupling shaft in a condition capable of standing against an initial tensile stress on the inner peripheral surface of an end at normal temperature side. CONSTITUTION:A normal temperature damper 7 is fitted to the end of a torque tube 8A through shrink fitting and a radial inward initial displacement is provided while the inner peripheral surface of a cylinder is provided with a tensile bending stress. Under this condition, the torque tube is fixed to a coupling shaft 6 through bolts A. The bending stress, generated in the inner peripheral surface of the cylinder of the torque tube 8A when the torque tube 8A is provided with a radial inward initial displacement of delta by fitting the normal temperature damper 7 into the end of the same tube 8A through shrink fitting, is shown by a formula. Accordingly, said stress may be cancelled by a thermal stress upon cooling when the initial displacement delta is selected at a proper value, therefore, the stress is mitigated.
