PURPOSE:To avoid the occurrence of a speed change shock due to a reverse drive transmission and prevent an operater from being given with the feeling of unpleasantness on account of a shock sound, by not conducting a speed change from a high speed step to a middle speed step, but conducting the speed change directly to a low speed step. CONSTITUTION:At the time of the coast travel of a transmissio...

PURPOSE:To form an electrode plate having long overcharge life by containing alkali methaphosphate and/or alkali pyrophosphate in an active material, and by applying, impregnating, or filling the active material in a current collector. CONSTITUTION:An active material contains alkali methaphosphate and/or alkali pyrophosphate. A current collector is coated, impregnated, or filled with this active m...

PURPOSE:To suppress water reduction in an electrolyte and capacity deterioration caused thereby even by high-rate constant-current charge by adding palladium ions into an electrolyte. CONSTITUTION:0.02 to 0.5g/l (saturation amount) per electrolyte volume of palladium hydroxide is added to an electrolyte as an oxygen reducing catalyzer. Palladium hydroxide added to the electrolyte is ionized, palla...

A kink preventing device for preventing occurrence of a kink in a yarn drawn out from a yarn supply bobbin of a winder includes a pair of kink bars supported for opening and closing movement with the yarn supply bobbin interposed therebetween and each having a contacting portion which is arcuately opened along an outer peripheral portion of the bobbin, and a kink bar opening and closing means for ...

A highly proportional solenoid is disclosed. An armature (60) having a conic indentation is attracted by a pole piece (10A) with a complementary tapered face (11), thereby providing an actuation which is highly linear in relation to applied electric energy.

Porous electrodes for lead acid storage batteries without supporting plates or grids. The electrodes are porous, self-supporting, structurally integral and electrically continuous. Lead-acid batteries incorporating such electrodes exhibit improved performance characteristics as compared to conventional lead-acid batteries. The electrodes are made by forming a molten mixture of metal (e.g. lead) an...

In or for a lead-acid battery, active material for its negative and/or positive plate(s) includes electro-conductive whiskers affording high degree of direct connection between active material particles and to base plate material. Electro-conductive whiskers are disclosed of at least one type selected from carbon, graphite and titanate with diameter of 10 mu m or less, aspect ratio of 50 or more,...

The functions M(y) and M(n) between the torque M of the engine, the position y of the accelerator pedal and the speed of rotation n are stored in an electronic control unit (13), in which the moment values pertaining to the measured acceleration signal and to the measured speed of rotation signal are picked out and a load signal s is generated. The signal s is compared with a constant shifting-up ...

A coextrusion head for producing a generally tubular elastomeric ply made up of first and second concentric tubular streams of elastomeric material having interposed, adjacent to their interface, a closely spaced array of parallel reinforcing elements wherein the coextrusion head includes a reinforcing element guide subassembly including a generally annular guide element as well as a mechanism for...

A method and apparatus for producing a coherent spray deposited product from liquid metal or metal alloy is provided. The method comprises atomising a stream of molten metal to form a spray and providing additional cooling by applying to the stream or spray relatively cold solid particles. The solid particles are preferably injected into the spray and may be formed from overspray particles recycle...
