PURPOSE:To make it possible to satisfactorily control the torque of an engine of such a type that the engine torque is increased and decreased by predetermined amounts during gear shift, by changing the above-mentioned predetermined values and a range in which the engine torque is controlled to be increased and decreased, when the frequency of increasing and decreasing the engine torque exceeds a ...

PURPOSE:To satisfy the economy of fuel consumption and drive feeling during normal running of a vehicle, by increasing hydraulic pressure fed into a frictionally engaging device which engages when engine brake is effected, only during an engine exhaust brake being operated. CONSTITUTION:There is provided a means for detecting whether an engine exhaust brake is on operation or not. There is also pr...

PURPOSE:To secure such an enclosed lead storage battery that is compact in size, thin type, and lighter in weight, by shallowing the depth of one side plate housing chamber to the utmost, while situating a void part of a plate collector to an inner bottom, and installing at least one reinforced projection being higher then plate height, then joining each interval between inner bottoms of the plate...

Disclosed is a process for fabricating a composite polycrystalline diamond or cubic boron nitride (CBN) compact. Briefly, the process is conducted by mating a pre-formed sintered polycrystalline diamond or CBN compact and a plastically deformable support, and subjecting the mated composite compact to elevated temperature and pressure conditions sufficient to plastically deform the support into att...

A hydraulically operable transmission comprises change speed gears, a hydraulic clutch, and a hydraulic circuit for operating the change speed gears and hydraulic clutch. The hydraulic circuit includes a plurality of hydraulic actuators interlocked with the change speed gears, and a pilot type control valve for controlling the hydraulic actuators. An oil line leading to the hydraulic clutch includ...

The invention relates to a method of welding together plastic pipes which are unwound from a roll, and an apparatus for regeneration of the shape of plastic pipes before the welding operation. The invention consists in that first of all the shape of the plastic pipe is regenerated by closely enclosing the plastic pipe over part of its length in a cylindrical mould, then heating up the mould until ...
