Title: Turning effort generating device
Inventor: YASHIRO TOMIO
IPC: F03G7/00
Filed: 1987-12-25
Abstract: PURPOSE:To enable the generation of controllable turning effort by installing an electromagnetic band formed by connecting a lot of magnet portions which can be controlled by switching on the inner wall of a rotary guide outer ring cylinder and rotating a moving arm having magnetic balls at both ends thereof along the electromagnetic band. CONSTITUTION:An electromagnetic band 2 formed by connecting a lot of magnet portions 21, 22 is installed on the inner wall 11 of a rotary guide outer ring cylinder 1. The electromagnetic band 2 is constructed so that the magnetic forces of the individual magnet portions 21, 22 are on-off controlled sequentially towards the rotating direction of a weight ball 5. A connecting pipe 6 for sliding is formed on a rotary main shaft 3 disposed at an eccentric position in the rotary guide outer ring cylinder 1, and magnetic weight balls 5 are fixed to both ends of a moving arm 4 slidably mounted on the connecting pipe 6. The rotary main shaft 3 is rotated through the moving arm 4 by the weight balls 5 which are attracted and moved to the left by the magnetic forces of the electromagnetic portions 21, 22 and by the drop motion of the weight balls 5 which have passed OFF point.

Filed: 1998-11-19
Abstract: PROBLEM TO BE SOLVED: To permit control of a vehicle with high accuracy and improve controllability by coaxially mounting a neutral position detecting cam and clockwise and counterclockwise turn detecting cams on a steering wheel supporting shaft and by operatively connecting a brake control arm and a trunnion arm of a static hydraulic pressure type continuously variable transmission.

Title: Control device for continuously variable transmission
Inventor: MORISHIGE TOMOTOSHI
IPC: F16H61/00
Filed: 1989-12-18
Abstract: PURPOSE:To prevent a delay in control response and hunting of speed change ratio by compensating the line pressure for a drive pulley in accordance with a variation speed by a speed change ratio, and simultaneously by compensating a control gain for the feed-back control of the speed change ratio. CONSTITUTION:If a variation speed by a speed change ratio is higher, the line pressure fed into a hydraulic cylinder 414 for a drive pulley is compensated up to a high value so as to rapidly change the effective radii of drive and driven pulleys 41, 42. Simultaneously, a control gain for the feed-back control of the speed change ratio is compensated to a large value. Meanwhile, if the variation speed by the speed change ratio is low, the line pressure is compensated to a lower value, and simultaneously, the control gain of the feed-back control is compensated to a small value. Thus, the shift speed can be suitable controlled, and the feed-back control of the speed change ratio is allowed to meet the shift speed, thereby it is possible to effectively prevent a delay in control response and hunting of the speed ratio.

Title: Injection device for injection molding machine
Inventor: TAMAKI MASAHIRO
IPC: B29C45/58
Filed: 1997-11-13
Abstract: PROBLEM TO BE SOLVED: To enable a motor for measurement and a motor for injection to be easily controlled and also the appropriate measuring operation to be performed with an accurate screw back pressure by arranging a rotary shaft and a transfer shaft maintained at a specified interval from each other. SOLUTION: In a measurement step, a rotary shaft 34 is rotated through a power transmission device 33 by energizing a motor 28 for measurement, and a screw 27 connected to the rotary shaft 34 integrally is rotated, and further, a material resin supplied to the interior of a heating barrel 22 is fed to a position forward of the screw 27 by the rotation of the screw 27 while being melted by the shear heat of a heating device. Then the material resin thus fed is accumulated and measured. On the other hand, the screw 27 is moved backward being pressed by the pressure of the molten resin which is accumulated and measured forward of the screw 27. During this process, the rotary shaft 34 moves backward rotating but is spaced from a threaded shaft 36 as specified.  Since the threaded shaft 36 is not influenced by the rotation of the rotary shaft 34, the back pressure applied to the screw 27 synchronizes the motor 28 for measurement with the motor 24 for injection and thus the necessity to perform a difficult control is eliminated.
