Title: Clutch system and webbing winding device
Inventor: HORI SEIJI
IPC: F16D43/24
Filed: 1998-03-04
Abstract: PROBLEM TO BE SOLVED: To transmit a turning force of a pretensioner to a spool when the pretensioner operates, without any resistance developing in the rotation of the pretensioner and without wasting any turning force for rotating the spool. SOLUTION: In a normal state, a roller 32 is locked by a lock projection 50 of a rotor 44 that constitutes a pretensioner. The roller 32 is not fastened between the rotor 44 and a shaft 22, so the shaft 22 rotates freely, and a spool can rotate freely for pulling out or winding up a webbing. When a vehicle suddenly decreases speed, the rotor 44 rotates, and the lock projection 50 is estranged from the roller 32, so the roller 32 is pressed by a taper 52 of a rotor 44 and fastened between an outer circumferential surface of the shaft 22 and the taper 52. The rotor 44 and the shaft 22 become linked via the roller 32, so the turning force of the rotor 44 is transmitted to the shaft 22, and the spool rotates to wind the webbing.

In this case, a variable setting signal S23 is inputted in this comparator 21 separately, and this signal S23 shows the preset value. The comparator 21 compares this setting value with the detected value out of the sensor 19, and when the detected value has exceeded the setting value, it is so judged that there is an overload state, outputting a warning. Consequently, tuning for this overload preventer 18 is good enough to merely regulate the variable setting signal S23, thus it is simple enough.

Abstract: PURPOSE: To continuously oxidize and decompose contaminants contained in waste water by utilizing a cavitation effect, by providing a waste water disposer with a rotor, and introducing heated oxygen gas together with the waste water into the disposer.  
     CONSTITUTION: Waste water introduced through the waste water inlet 16 of a disposer is carried through a rotary cylinder 5 by the suction pump 4 of a rotor 2, to a suspended solid-separating opening 7 at the part to which discs 6 are attached. Suspended solids are discharged through a solid-discharging pipe 8. The separated waste water is further carried through the rotary cylinder 5 by a spiral plate 10, and dispersed by a bladed plate 11. At this time, a negative pressure is generated inside the bladed plate 11, so that heated air or oxygen gas is introduced through a conduit 13. The oxygen-containing gas is divided into dispersed fine particles by projections 12 such as a brush or the like, and cavitation occurs concurrently around the projections 12. Besides, the temperature of the waste water is raised by the injection of the heated oxygen-containing gas, so that electrons contained in the contaminants of the waste water will be excited. Consequently, the contaminants are oxidized and decomposed with high efficiency.
