Title: Ball-inclined face mechanism for joining rotary member
Inventor: ROSCOE CHARLES S
IPC: F16H48/30
Filed: 2001-11-21
Abstract: PROBLEM TO BE SOLVED: To provide a differential clutch operating system having improved sensitivity, and an improved cam inclined face axial direction moving distance with respect to cam inclination, and providing both actions of advancing and retreating. SOLUTION: A ball inclined face passage has a double ball inclined face actuator 80 for following mutually overlapped eccentric grooves 84a and 84b operable in both directions of the advance and the retreat. Inclination is reduced (to a half), by mutually overlapping eccentric ball inclined faces, and an angle- moving distance is increased (doubled effectively). The clutch operating action is generated in both directions of advancing and retreating. A central control ring 84 rolls two sets of balls 86 of respective side parts by a doubly-inclined face three-piece sandwich structure. This structure can double the axial direction moving distance for pressing a disk pack more as compared to a singly-inclined face system including only two inclined faces, and is usable for locking a differential having the same ball inclination.

Inventor: OKAMURA GEN
IPC: A63F5/04
Filed: 2001-11-22
Abstract: PROBLEM TO BE SOLVED: To reinforce a lower plate without hindering detachment and attachment of the lower plate. SOLUTION: When a lower plate supporting frame 19 having a lower plate 16 is mounted to a supporting frame mounting portion 120, pressing members 121 to 126 press three positions of the upper side and the lower side of the periphery of the lower plate 16 from the reverse side. Therefore, even if struck or pushed from the surface side, the lower plate 16 does not easily get warped or broken since the lower plate 16 is reinforced with the periphery pressed by the pressing members 121 to 126. Since the lower plate 16 is attached to or detached from the lower plate supporting frame 19 with the lower plate supporting frame 19 removed from the supporting frame mounting portion 120 of the front door 12, the pressing members 121 to 126 provided in the front door 12 do not interfere with the attachment and detachment.

Filed: 2001-11-28
Abstract: <P>PROBLEM TO BE SOLVED: To provide a flexible coupling, with which a work of modifying the connection between an existing manhole and a pipe into an earthquake resistant structure can be completed inside the manhole.  <P>SOLUTION: The flexible coupling (a) is fitted into the gap between a drilled hole and the end of the pipe from the inside of the manhole body. The flexible coupling has tapered surfaces 14, 24, which is the tapered front ends of coupling members 4, 5 fixed to the inside and outside of a sleeve 1 via inside and outside rings 2, 3, respectively. When the tapered surfaces 14, 24 are pressed into the gap, the flexible seals 15, 25 on the tapered surfaces come in slide contact with the interior wall of the drilled hole or exterior wall of the pipe as the seals deform elastically, thus the coupling (a) is ultimately fixed between the interior wall of the drilled hole and the exterior wall of the end of the pipe. Coupled together via the bendable coupling (a), the manhole body and the pipe are held flexible in their move, being able to follow the fluctuation of the ground due to earthquake, differential settlement and the like. Thus, breakage of the pipe on the connection with the manhole can be prevented and the watertightness of the pipe is also maintained.  <P>COPYRIGHT: (C)2003,JPO
