PURPOSE:To make is possible to mechanically, automatically and simply knot threads, irrespective of kinds of threads, by forming grooves in the facing surfaces of a pair of blocks, corresponding to the paths of threads to be knotted together, and by providing an air stream producing means directed to the openings of the paths. CONSTITUTION:Blocks 1, 3 are closed so that their facing surfaces 11, 3...

PURPOSE:To reduce the influence due to oil temperature by assembling a spring made of shape memory alloy onto a valve for controlling the supplied hydraulic pressure, in a hydraulic controller equipped with said valve communicating to the frictional engagement elements assembled into the hydraulic circuit of a transmission for vehicle. CONSTITUTION:The lower part of a valve spool 32 is formed long...

PURPOSE:To make drive feeling constant by providing a throttle opening sensor detecting throttle opening and a speed change control device having an inclination hysteresis bestowing means and a speed change controlling means. CONSTITUTION:A throttle opening sensor 303 detects actual throttle opening. A speed change control device 300 controls action of a step motor 110 and a solenoid 224. On the s...

PURPOSE:To make speed change characteristic variable with a simple construction by making speed change characteristic variable with changing of a lever ratio of a correction lever be small at lower stage side than a fixed gear ratio while to be large at higher stage side. CONSTITUTION:Engine brake is acted by down shift of a gear ratio control valve 90 to higher engine speed side with actuation of...

PURPOSE:To make feeling of speed change in kick down good, together with getting sufficient driving force in full open starting by providing a gear ratio detecting means, an engine load detecting means, a judging means and a speed change pattern changeover means. CONSTITUTION:When throttle opening is judged by a means C to be fully open, whether the vehicle is in full open state or in kick down ac...

PURPOSE:To suppress vibration on a vehicle body in Ds range by constituting the device such that a speed change line with small change is fixed in engine speed in extra low speed range of sporty drive(Ds) range, and a speed change line with large change is fixed in engine speed in proportion to gear ratio in medium and low speed range. CONSTITUTION:The device is made so as to change speed to the d...
