Title: Lifting and lowering of ring rail when starting spinning machinery and controller for lifting and lowering of ring rail
Inventor: SHIBUYA MAKOTO
IPC: D01H1/36
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To reduce the occurrence of yarn breakage when forming an oblique loop winding at the time of starting spinning machinery and then performing the usual winding. SOLUTION: An oblique winding is formed before performing the usual winding at the time of starting a spinning frame and the winding by a usual chase length is then carried out. When the winding by the usual chase length is performed, a ring rail is initially lifted and lowered at a higher prescribed speed than a lifting and lowering speed at the time of the usual winding a prescribed number of times, and then transferred to the lifting and lowering speed when performing the usual winding. The ring rail is lifted and lowered at a high speed even in a state of the tip of the oblique loop winding separated from a bobbin surface or a snarl remaining in a yarn. Thereby, the yarn is rapidly immobilized in the surface of the bobbin.  The lifting and lowering speed and the frequency of lifting and lowering when lifting and lowering the ring rail at the high speed are set at suitable values corresponding to spinning conditions.

Title: Pickup driving device
Inventor: NAGATSUKA KUNISHIGE
IPC: G11B21/12
Filed: 1977-09-29
Abstract: PURPOSE: To let the pick up descend slowly and smoothly at the reproduction and let the same ascend rapidly upon ending of the reproduction by slowly and rapidly controlling the displacements of a permanet magnet depending upon the current supply condition to an electromagnetic coil.  
     CONSTITUTION: Non-magnetic materials 11 are interposed among a flat plate form permanetnt magnet 6, a flat plate form yoke 1 and a yoke part 5 to prevent unnecessary contacting of the magnet 6 and yoke 1 or yoke part 5. Since the d.c. current to an electromagnetic coil 2 increases sharply at the beginning of supply and the rate of the increase gradually decreases and approaches to a specified value in the due course of time, the descending of the magnet 6 becomes slow and smooth and the rate of descending becomes mild along with descending. Next, when the current of the coil 2 is cut off, attraction force is developed among the magnet 6, yoke 1 and yoke part 5 and at the same time the elastic force of an elastic body 7 causes the magnet 6 to ascend rapidly. This enables the pickup linked to the permanent magnet to be descended slowly and smoothly toward the record side at the reproducing and to be rapidly ascended upon ending of the reproduction

Filed: 1989-05-11
Abstract: PURPOSE:To avoid a control delay during start after engine stall by stopping the energization of a valve means for feeding hydraulic pressure to a hydraulic actuator in a valve timing mechanism when a detected vehicle speed is lower than a predetermined value. CONSTITUTION:A valve timing changing mechanism 3 changes the relative phase between the valve opening timings of intake and exhaust valves in accordance with a hydraulic pressure fed to a hydraulic actuator 1 by a valve means 2 upon energization. Further, a control means 4 controls the energization of the valve means 2 in accordance with a driving condition. With this arrangement, A means 5 detects a vehicles speed. If thus detected vehicle speed is lower than a predetermined value, a means 6 stops the energization of the valve means 2 by the means 4. That is, a hydraulic actuator 1 is released under such a condition that the vehicle speed is lower than a predetermined value, and accordingly, the valve timing changing mechanism 3 is set to an initial position where the valve overlap is small.
