Title: Belt type torque control system
Inventor: TAKANO HIROSHI
IPC: G05D17/02
Filed: 1985-03-29
Granted: 1989-11-09
Abstract: A belt-type torque control system wherein a power transmission belt is entrained about a pair of variable speed pulleys. One of the pulleys includes coaxially mounted pully halves, one of which is fixed to a drive shaft and the other of which is axially and rotatively movably mounted thereto. A coil spring extends between the movably mounted coil half and a spring retainer fixed to the shaft urging the movable pulley half toward the fixed pulley half. The coil spring causes a variation in the spacing between the pully halves as a function of the belt force applied thereto in operation of the drive. The angular displacement of the movable pulley half is sensed by a control including sensing elements associated with the movable pulley half and sensing elements associated with the fixed pulley half so as to provide a differential angle, or phase, difference signal which is used by the control for adjusting the other adjustable pulley, thereby to maintain the adjustable pulley with which the sensing means is associated within a preselected range of angular displacement between the fixed and movable pulley halves thereof.

Abstract: In the production of a grain-oriented electrical steel sheet, instead of conventional inhibitors a novel (Al, Si)N inhibitor is utilized. This inhibitor is formed by obtaining an incomplete solution of Al and N and then nitriding the decarburization annealed steel sheet prior to initiation of a secondary recrystallization. The fine inhibitor can be formed in a large amount, thereby enhancing the magnetic flux density.

Abstract: In a known method of friction welding two workpieces together, one workpiece is reciprocated relative to the other while the workpieces are pressed together. When sufficient frictional heat has been generated, relative movement is caused to cease and the workpieces become welded. Apparatus for carrying out that method comprises power-driven reciprocatory means (5;5 min ;10;10 min ;9;12;11) which carries the reciprocating workpiece. To balance the reciprocatory means there are counterweights (20;21;27) which move in the opposite direction to the reciprocatory means. Each counterweight is constrained to guide means (98) to move along a rectilinear path. Each counterweight is coupled to the reciprocatory means by reversing means, which comprises a pivoted rocker (14;15;24), first linking means (16;17;25) and second linking means (18;19;28). Each linking means may be constituted by a flexible blade which is anchored in a non-pivotal manner to the reciprocatory means, the rocker or the counterweight, as the case may be.
