Title: Escalator for out-door use
Inventor: MATSUBA KENJI
IPC: B66B31/00
Filed: 1995-10-19
Abstract: PROBLEM TO BE SOLVED: To return lubricating oil to an oiling device and prevent the occurrence of environmental contamination by separating turbid water into original lubricating oil and rainwater, and discharging only the separated rainwater. SOLUTION: Rainwater drops to a drain pan 13 as turbid water, together with lubricating oil fed to a chain, when it rains. The turbid water flows into the first reservoir 16 via the drain pan 13. The turbid water is composed of the lubricating oil and the rainwater, and, therefore, the rain water is separated into a lower layer with the lubricating separated into an upper layer. Then, the rainwater separated in the first reservoir 16 and positioned in the lower layer flows into the second reservoir 17 via a communication port 18. In this case, a float switch 26 positioned beneath the separated lubricating oil prevents the flow thereof to the second reservoir 17 via the communication hole 18. When the rainwater in the second reservoir reaches the prescribed level, the float switch 24 is turned on.  A pump P2 begins to operate, when the float switch 24 is turned on, thereby pumping out the rainwater in the second reservoir 17 to a drain gutter. According to this construction, environmental pollution can be prevented.

Inventor: HIROSE MASAHIKO
IPC: B62D5/083
Filed: 1997-09-17
Abstract: PROBLEM TO BE SOLVED: To impart a desired rigid feeling during strait-ahead running with a mechanical structure. SOLUTION: The oil pressure supplied to a hydraulic actuator for generating steering-assist force is controlled in accordance with the elastic rotation of relative steering torque of an output shaft through a torsion bar 3 to an input shaft. A rolling member 63 is interposed between a presser part 61 adapted to move relative to either of the shafts axially and corotate with it and a receiver part 62 adapted to corotate with the other. The elastic force that causes the presser part 61 to press the rolling member 63 against the receiver part 62 is produced by a elastic member 65.  During straight-ahead running, the rolling member 63 is positioned between concavities 61e and 62e formed in the presser part 61 and the receiver part 62 to thus check the relative rotation of both the shafts while the steering torque falls below a preset value and to allow the relative rotation while the torque equals or exceeds the value. The elastic force is made variable so that the preset torque value is adjustable.
