Filed: 1988-12-27
Abstract: PURPOSE:To enable drive power to be ensured in restarting time while improving a feeling in coasting down time by using in common a clutch and a lockup clutch performing a main speed change mode of a forward-reverse selecting mechanism providing a one-way clutch. CONSTITUTION:In an H range of a main speed change mode, a lockup clutch CL is connected placing a starting device 1 and a primary pulley 8 in a directly coupled condition. That is, a direct coupling clutch and the lockup clutch CL are placed in common of a forward-reverse selecting gear mechanism 4. While in an L1 range, because a brake B1 is connected, carriers 5c, 6c are decelerated rotating transmitting rotation to a fixed sheave 8a. While in vehicle deceleration time or the like, because power from the pulley 8 is transmitted from a ring gear 6r to the starting device 1, an engine brake is applied. Further in an L2 range, because only a brake B2 is connected transmitting power from an engine similarly decelerated to the L range by a one-way clutch F but no reverse power, the engine brake is not applied.

Title: Continuous girder bridge
Inventor: SUGIZAKI MAMORU
IPC: E01D19/12
Filed: 1997-11-14
Abstract: PROBLEM TO BE SOLVED: To construct easily and costlessly a continuous girder bridge and secure a compression-resistant stress at the lower side of a bridge body by extending the steel girders in the bridge-axial direction and supporting floor slabs and arranging concrete slabs in between the lower flanges of adjacent steel girders to form a box-shaped structure. SOLUTION: Precast slabs fabricated in a factory are connected to form a concrete slab 12. The shrinkage after it has been started to use is fine and hence, the function for compressive stresses is hardly decreased. And the spaces between steel girders 11 are closed by concrete slabs 12 to shield the outside air and prevent rust resulting from stagnant moisture or bird nests or the like. The concrete slabs 12 are used as scaffolds on inspecting and maintaining the girders to facilitate these works. The lower flanges 11L of steel girders 11 are concreted by the concrete slabs 12 to form a highly rigid girder 10. And compressive stress resulting from a negative bending moment are supported by the concrete slab 12. In this way, the continuous girder bridge can be costlessly manufactured and transported and further, the degree of freedom of the bridge design can be improved.
