Abstract: PROBLEM TO BE SOLVED: To reduce shock at the time of starting start-assisting, and to restrain the rush current of an electric motor to a low level, in a device constituted to drive the driven wheel of a vehicle by the electric motor to assist the start. SOLUTION: A hydraulic clutch 8 is interposed in a power transmission route between an electric motor 6 and driven wheels 4L, 4R to supply oil to the clutch 8 by a hydraulic pump 10 driven by the motor 6. Oil supplying pressure from the pump 10 is low in a low rotational-speed region of the motor 6 to generate slide of the clutch 8. Driving torques of the driven wheels 4L, 4R are thereby led moderately.

Abstract: Improved assay methods utilizing stable, enzymatically triggered chemiluminescent 1,2-dioxetanes with improved water solubility are provided. Assays are performed by a capsule chemistry analytical assay method wherein fluid capsules comprising discrete aqueous segments containing either a chemiluminescent dioxetane reagent or an activating agent separated by an oil-based isolating fluid are flowed through a conduit, and subsequently reacted to produce light. The improvement comprises using a dioxetane substituted with two or more water-solubilizing groups disposed on the dioxetane structure to provide the chemiluminescence. Compositions comprising such a dioxetane, a non-polymeric surfactant enhancer and optionally a fluorescer, provide enhanced chemiluminescence and eliminate the problem of reagent carryover when used in assays performed on capsule chemistry analytical systems. <IMAGE>
