Title: Winding stem control structure of timepiece
Inventor: YAMADA SHINICHI
IPC: G04B27/04
Filed: 1986-01-31
Abstract: PURPOSE:To improve the durability of a setting lever by winding stem operation and to use parts in common by allowing a setting lever dowel to strike on a receiving member nearby the center line of a winding stem during the operation of the setting layer and controlling the operation of the winding stem. CONSTITUTION:The winding stem 2 is pushed and pulled to rotate the setting lever 3 which is fitted in a winding stem step part 2a around a setting lever shaft 6. Then when the winding stem 2 is pulled by one stage, the setting lever dowel 4 moves from a position(a) to a position (b) and when the winding stem is pulled by two stages, the dowel 4 moves to a position (c) to position the setting lever 3. The dowel 4 strikes on the abutting part 5a nearby the center line of the winding stem at the position (c) and the winding stem 2 can not be pulled any more. Further, when the dowel 4 is at the position (c) and the winding stem 2 is pushed in, the dowel 4 strokes on an abutting part 5b nearby the center line of the winding stem while the dowel 4 is at the position (a) at the time of the most intrusion of the setting lever 3 and can not be pushed in any more, so that the winding stem 2 is prevented from being pulled and pushed too much. Further, the specification of the one-stage drawing or two-stage drawing of the winding stem 2 is dealt with without replacing any component except the setting lever 3.

Title: Condensed oxygen supplying device
Inventor: HIRATA MINORU
IPC: A61M16/10
Filed: 1996-01-10
Abstract: PROBLEM TO BE SOLVED: To secure a quiet operation by suppressing noises caused by the pressure fluctuation of a compressor for sucking air. SOLUTION: Suction cylinders 5 and 6 condense oxygen from air, and condensed oxygen is ejected from a nozzle 22 of a humidifier 21 through a tank 7. The air is sucked into a suction tank 21 by driving a compressor 2 and supplied to the suction cylinders 5 and 6. The pressure of air is relaxed inside the suction tank 2 and even when the pressure of compressor 2 is fluctuated, there is no pulse current in the sucked air. A muffling member 30 arranged at a suction hole 9 of the suction tank 2 absorbs a little pulse current caused by the pressure fluctuation of compressor 2. The noises caused by the pressure fluctuation of compressor 2 can be suppressed by the suction tank 1 and the muffling member 30.
