IPC: F16H57/04
Filed: 1988-11-30
Abstract: PURPOSE:To prevent leakage of a lubricant in a machine even if internal pressure changes by providing means for absorbing volume changes of a lubricant poured into a speed change mechanism portion in a transmission and gas sealed therein, which are caused by temperature change. CONSTITUTION:A volume adjusting bag 30 is installed in a through-hole 22a provided in a case 22, with a bag opening 30a opened to the inner space 28 of a transmission 2, protected by a cover 31 fixed to the case 22 and mainly filled up with sealed gas of the transmission 2. Even if with the rise and fall of the temperature in the transmission 2, a lubricant and sealed gas filled in the inner spaces 28, 28a cause a volume change, the volume changes come into pressure changes to be absorbed by expansion or shrinkage of the volume adjusting bag 30, so that the internal pressure of the transmission 2 is kept near the outside air pressure to eliminate any influence upon each sealed joining portion. Accordingly, it is possible to prevent lubricating material in a machine from leaking together with sealed gas outside the machine through the sealed joining portion.

Title: Starter
Inventor: NIIMI MASAMI
IPC: F02N15/06
Filed: 1995-11-22
Abstract: PROBLEM TO BE SOLVED: To miniaturize an electric current limiting means so as to make a starter compact by preventing the electric current limiting means from being heated. SOLUTION: The first switch 21 and the second switch 24 which are sequentially connected when a plunger 14 is moved upward are received in the housing 15 of a magnet switch 7. The first switch 21 passes a current through a starter motor 4 via a current limiting means 25 to rotate a pinion 3 at low speeds and the second switch 24 passes a current through a starter motor 4 without the current limiting means 25 to rotate a pinion 3 at high speeds. A time limiting means 26 of a bimetal switch which is heated by itself to open a contact when a current is fed is connected to the current limiting means 25 in series.  If the second switch 24 is not connected after the first switch 21 is connected, the time limiting means 26 or the bimetal switch is heated to switch off, thereby stopping passing the current through the current limiting means 25 to prevent the current limiting means 25 from being heated, which results in making the current limiting means 25 and then the starter 1 compact.
