An automatic transmission comprises a friction engaging means having a plurality of first plates spline-fitted to a hub and a plurality of second plates spline-fitted to a drum and disposed in an interleaving relation to the first plates, an one-way clutch provided in the hub and having a plurality of sprags for locking the rotation of the hub when the hub rotates in a locking direction and a control means for temporarily releasing the friction engaging means for a specified timespan when the fr...

To provide an automatic warehouse that can elevate and lower an elevating rail stably even if racks are high, and that allows effective use of the space between the racks for maintenance. Elevation drive sections for an elevating rail 3 are provided near the respective ends of one of racks 1 and 2, a rope 40 attached to a rail-supporting member 12 is wound around a drum 22, and a counterweight 24 is used to balance the effect of gravity in order to elevate and lower a rail 3. A travelling cart 4...

An automatic decapper removes caps from capped test tubes by gripping the cap on a test tube with the upper grippers and holding the cap stationary while the test tube is rotated and translated downward with lower grippers. In a preferred embodiment, the upper grippers comprise three jaws coupled to a cam to be moved, as appropriate, from a first position in which a test tube cap may be inserted between the jaws to a second position in which the jaws grip the inserted cap. The upper grippers are...

The present invention is a quiver having: a housing having a top end an a bottom end and an opening between the top and bottom ends for the insertion and removal of arrows and a carousel mounted inside the quiver for the positioning and delivery of arrows. The carousel of the quiver of the present invention has a rotatable shaft in the center of the housing, at least one means attached to the rotatable shaft for gripping arrows, a shaft mount associated with the top half the housing for mounting...

Without causing an increase in size and complication of an automatic analyzer, the efficiency of washing cuvettes can be increased and the amount of detergent used can be more effectively saved in comparison with known analyzers. In an automatic analyzer in which a sample and a reagent are dispensed into each of a plurality of cuvettes, a resulting reaction solution is mixed under stirring, and reaction states of the mixed reaction solution are measured successively. The automatic analyzer inclu...

The output rotation of an engine is transmitted to a drive member when a vehicle starts moving, and the drive member is connected to a carrier of a speed-increasing planetary gear via a start clutch. Upon engagement of the start clutch, the rotation of the drive member is accelerated by the speed-increasing planetary gear and then transmitted to an input shaft that is directly connected to a ring gear. Such rotation transmitted to the input shaft is shifted to a plurality of speeds and transmitt...

An automatic transmission comprises a planetary gear train (PG) including a sun gear (S) connected to a first main shaft (3), a carrier (C) and a ring gear (R); a first gear train (G1) including a first drive gear (6) connected to the ring gear (R), and a first driven gear (7) disposed rotatably over a countershaft (5) and meshed with the first drive gear (6); a third gear train (G3) including a third drive gear (10) disposed rotatably with respect to the carrier (C), and a third driven gear (11...
