PURPOSE:To make it possible to contain magnesium ions having a specified concentration in an electrolyte by only pouring a usual electrolyte by arranging a granulated magnesium salt inside an instant-use type lead-acid battery. CONSTITUTION:An instant-use type lead-acid battery 1 consists of a container 2 and a cover 3, and no electrolyte is poured in it. A plate group 4 is accommodated in the con...

PURPOSE:To reduce the factor of labor for assembling a speed change gear and to smoothly reduce the speed change gear in its weight by solidly forming side walls clamping a sun gear and a planetry gear and a guide wall for guiding lubricating oil to a engagement portion with a metal plate by pressing. CONSTITUTION:A lubricating oil flow-out device 45 of a speed change device T includes the first a...

A splicing apparatus for spun yarns comprises a splicing member which has a cylindrical splicing hole, a slit for insertion of the yarns and a jet nozzle jetting a compressed fluid and opened to the splicing hole in the tangential directions, and yarn end control nozzles, yarn cutting devices, a yarn guiding means and yarn clamping devices, which are arranged in sequence on both sides of the splic...

A splicing apparatus for spun yarns includes a splicing member having a splicing hole and a jet nozzle jetting a compressed fluid. Yarn end control nozzles, yarn cutting devices, a yarn gathering lever and yarn clamping devices are arranged in sequence on both sides of the splicing member. The yarn gathering lever for taking out the yarn ends left in the untwisting nozzle is regulated with the qua...

A structure of a joint of spun yarns formed by lapping the tops of two yarn ends in the untwisted state and jetting a compressed fluid to the lapped portion while keeping the tops of the yarn ends free without securing the tops of the yarn ends. In at least one portion of the joint, fibers of the two yarn ends are integrated to form one yarn having twists of the same or opposite twisting direction...

A pneumatic yarn splicing apparatus for splicing spun yarns including two nozzle pipes for untwisting and attracting yarn ends to be spliced and a yarn splicing member having a yarn splicing hole which is disposed between the nozzle pipes. The nozzle pipes have opening areas reduced with respect to the diameter of the nozzle pipe to increase the speed of flow of the suction stream of air.

PURPOSE:To obtain always good spliced condition with a splicing arrangement, in which a thread end is set in a nozzle pipe and untwining is made under action of a jetting stream, by changing the jetting position of the stream in nozzle pipe in relation to the twining direction of the thread's own. CONSTITUTION:This untwining device has a thread-end untwining pipe 26 fitted in a nozzle hole 12 of b...

PURPOSE:To prevent irregular splicing owing to pressure drop in the compressed air by furnishing a pressure switch at a pipe to supply compressed air to a pneumatic splicing device and by stopping the automatic winder when the pressure of compressed air becomes below a certain specified value. CONSTITUTION:Piping for compressed air in an automatic winder 1 is leading from a main tap 7 to a first p...

PURPOSE:To approximate the operation of an engine to an ideal condition, by making calculations with a microcomputer to put the operation of the engine in the condition desirable as to fuel efficiency and accelerating performance and by indicating the results of the calculations to the operator. CONSTITUTION:A detection signal of the revolution speed of an engine 1 is applied as input information ...
