IPC: E02D5/80
Filed: 1992-12-04
Abstract: PURPOSE:To prevent the lowering of strength of an unbonded steel wire by bending the unbonded steel wire, held in the groove of a guide cone, into U- shape along the groove of the guide cone at the time of the unbonded steel wire passing in a guide ring, together with a load bearing body. CONSTITUTION:A constrained pipe 5, a guide ring 7, a guide cone 4, an anchor load bearing body 3 and a jack 8 are disposed in relation to fixed plates 9. An unbonded steel wire 2 is disposed in the groove of the guide cone 4. The anchor load bearing body 3 and the guide cone 4 are then extended toward the guide ring 7 by extending the jack 8.

Title: Cylinder having cushion device
Inventor: HASHIGUCHI MASABUMI
IPC: F15B15/22
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive cylinder in which a piston or a piston rod does not abruptly collides with a wall surface at its advancement limit or at its retreat limit. SOLUTION: A piston is moved forward or backward by injecting fluid to a pressure chamber from a fluid port or exhausting the fluid therefrom. The fluid port has a speed reducing valve which serves to reduce the exhaust of the fluid when the piston comes near to a wall surface. Thus, resistance to the movement of the piston is generated, so that the speed of the piston is reduced and an abrupt collision is prevented. Such a speed reducing valve can be easily realized at low cost by a constitution having a cushion cap 101, a cushion valve 102, a spring and a spacer.

Abstract: PROBLEM TO BE SOLVED: To detect play and friction of a ball screw easily and surely by a single device by providing a nut holding jig with a holding mechanism which can selectively switch a nut freely between an unrotatable state for detecting play and a rotable state for detecting friction. SOLUTION: A nut holding jig 18 is provided with a holding mechanism 56 for selectively switching a nut 16 freely between an unrotatable state and a rotatable state.
