Abstract: In a compressor in which a compression mechanism incorporated in a housing is driven by a drive shaft penetrating the housing, and the compression mechanism is lubricated by mist-form lubricating oil contained in a low-pressure gas refrigerant sucked into the housing, the lubricating oil in a space is prevented from entering a bearing and deteriorating grease in the bearing. An equalizing hole is formed to allow the space to communicate with the atmosphere, the space being defined between the bearing pivotally supporting the outer end of the drive shaft on the housing and a shaft seal disposed on the inside of the bearing to seal a gap between the drive shaft and the housing.

Abstract: A compressor having a capacity-controlling mechanism is provided, by which the inner-peripheral surface of a blind opening provided in a piston is subjected to abrasion due to sliding and rotating motions of a coil spring in the piston. In the capacity-controlling mechanism, the coil spring is covered by a cover made of abrasion resistant material and the covered coil spring is arranged in the blind opening, or a head of the coil spring is engaged to an inner surface of the blind opening.

Abstract: An automobile side panel with a space defined therein is welded by positioning a plurality of outer panel components with a plurality of first clamping mechanisms, welding the positioned outer panel components into an outer side panel member, positioning an inner side panel member in superposed relation to the outer side panel member with a plurality of second clamping mechanisms, and welding the positioned outer and inner side panel members into a side panel, with the space defined between the outer and inner side panel members. The outer panel components and the outer and inner side panel members are welded in one welding station.

Abstract: A fishing reel comprising a housing including frame members. A spool member is provided containing a spool shaft supported between the frame members. A pinion gear member is slidably mounted on and movably engagable with the spool shaft. A main gear member is rotatably disposed within the housing, the main gear member is connected to a handle shaft member and is rotatable therewith. The main gear member is operably engaged with the pinion gear, and a clutch mechanism is mounted on the frame members and is operably connected to the pinion gear for movably engaging the pinion gear on the spool shaft, whereby the spool member is placed under load by either manually reciprocating the clutch mechanism to enable the pinion gear to engage with the main gear or by turning the handle to automatically enable the pinion gear to engage with the main gear.

Abstract: For rotating the runner of a fluid machine in compressed air atmosphere in the runner chamber after shutting off working water and feeding compressed air to the runner chamber to move the liquid level therein downwardly below the runner while discharging water remaining in the outer peripheral portion of the runner through a leak-water exhaust pipe following starting of pump-operation, an inlet valve opening detector is mounted and operatively connected to a leak-water exhaust valve controller for controlling a leak-water exhaust valve. Stable operation of the fluid machine in spinning-in-air mode can be achieved by opening the leak-water exhaust valve by means of the leak-water exhaust valve controller following lapse of a given period of time after the inlet valve is fully closed, to permit the water remaining in the outer peripheral portion of the runner to be discharged through the leak-water exhaust pipe.
