Title: Hot galvanizing method
Inventor: ONO YOSHIO
IPC: C23C2/20
Filed: 1979-12-12
Abstract: PURPOSE:To eliminate dispersion of galvanizing amount in the longitudinal direction of steel strip and lessening defect in area reduction during the high-speed thin glavanizing process by separating tension of the steel strip in a pretreatment furnace and the tension of the steel strip in a nozzle for air-throttling after passing through a melting spot into respetive given tension ranges. CONSTITUTION:A steel strip 1 is sent through a pretreatment furnace 2 and a bridle device 6 to a melting spot 3, the amount of molten metal for plating is controlled by a nozzle 4 for air throttling, and then it is sent through a top roll 5 to the next process. In this case, tensions imposed on steel strip can be regulated independently in a furnace 2 and the nozzle because of the installation of the device 6. In short, the tension of the steel strip 1 in the furnace 2 is regulated at 0.3-0.6kg/mm.<2>, while the tension of the steel strip in the nozzle portion is at 0.5-6.0kg/mm.<2>. As a result, the maximum oscillating amplitude of the steel strip 1 at the nozzle portion can be regulated to approx. 1/4 in contrast with the conventional plating method in which tension is in a range of 0.3-0.6kg/mm.<2> as a whole. Thus, the tension of the steel strip in the furnace 2 can be kept constant and thereby the cutting of the strip in the furnace 2 can be reduced.

Title: Position information generator for step motor
Inventor: JIYANNKUROODO BERUNEI
IPC: G05B19/06
Filed: 1980-11-15
Abstract: The device comprises a stepper motor (20, 21, 22) controlling, through intermediate wheelwork, a wheel (23) carrying at least one soft-iron cam (24) of triangular shape. On each wheel revolution, this cam passes in front of a fixed permanent magnet (25) which exerts a force of attraction on the cam. In a first phase, the attraction acts in the direction of motion of the wheel (23), this being equivalent to a reduction in the load of the motor, hence to a reduction in the time taken by the rotor (20) to perform its step. Then, when the cam moves past the magnet, the attraction acts in the direction opposite to the rotation of the wheel, this tending to increase the time taken by the rotor to perform its step. An electronic circuit detects these variations in duration of the steps of the rotor and delivers information characterising the position of the cam with respect to the magnet. <IMAGE>
