Title: Switch mechanism
Inventor: SUGA TAKESHI
IPC: H01H21/28
Filed: 1988-04-06
Abstract: PURPOSE:To prevent a contact in a switch from being over-loaded when the switch is over-loaded by providing therein a member which restricts pressure applied to the switch in the specified amount. CONSTITUTION:A push button 1 is operated by the pressure of its actuater 1a. In the distance b and c shown in the figure from a wall to which the actuater 1a is attached to its end, the push button 1 is normally operated, so that if the pressure is continually applied beyond the distance c, the mechanism in the push button 1 is over-loaded. The push button 1 is fixed by a switch supporting board 3 and pressed with 1 pressing board 8 which revolves by external force as a shaft 2 is a supporting point. By arranging the dimension of a restricting member 10 provided at the end of the pressing board B in m<1<n, the end of the restricting member 10 touches the switch supporting board 3 so that the push button 1 is prevented from being applied with excessive force therein.

Title: Tool holding device
Inventor: MIYAGAWA SAIJI
IPC: B23B31/117
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To provide a tool holding device which efficiently coverts tractive force of a draw bar into holding force of a collet chuck, in which failures are hard to occur and which can be easily designed. SOLUTION: In the engagement of the rear end of a collet chuck 2 with the part near the tip of a draw bar 1, either one of the inside engaging face of the collet chuck 2 and the engaging face of the draw bar 1 on the opposite side of the inside engaging face is defined as a tapered face (b) sequentially reducing the diameter in the rear toward the center side, and the other is made nearly circular arc or nearly elliptic arc (a). In the engaging relationship between the rear end part of the collet chuck 2 and the rear end part of a sleeve 31 of a spindle, either one of the outside engaging face of the collet chuck 2 and the engaging face of the sleeve 31 on the opposite side of the outside engaging face, is defined as a tapered face sequentially enlarging the diameter in the rear, and the other is made nearly circular arc or nearly elliptic arc (a).  Thus, on the basis of these facts, tractive force of the draw bar 1 is allowed to be efficiently converted into holding force of the collet chuck 2 without requiring the strict accuracy in designs.

Title: Cathode for carbon dioxide laser device
Inventor: IZUHARA MASAMI
IPC: H01S3/038
Filed: 1987-04-06
Abstract: PURPOSE:To realize oscillation of high power laser beams which are stabilized for a long term, by coating a surface of a cathode with conductive oxide so that a cathode material is prevented from vaporizing during discharge. CONSTITUTION:A surface of a cathode 6, which is made of molybdenum, stainless steel, or the like and L rod-shaped, is coated with a conductive oxide thin film 10 made of SnO2, ZnO, In2O3, or the like by physical evaporation methods such as a sputtering method, an ion plating method, or the like and a chemical evaporation method such as a CVD process or the like. The surface of the cathode 6, whose surface is thus coated with the conductive oxide thin film, is not corroded in recessed and projecting shapes because the cathode material is prevented from vaporizing during discharge. Further, since oxide is not stuck on the surface of the cathode, it is not stuck also on the surface of the anode, so that deformation of a surface shape and contamination do not occur on the anode. High power laser beams which are stabilized for a long term can be oscillated accordingly.
