Abstract: PURPOSE:To simplify a control circuit for regenerative braking, by a method wherein a saturated condition of reverse polarity of a speed discriminator, which is generated when the regenerative braking is effected during normal operation, is confirmed to switch the conducting condition of a motor. CONSTITUTION:3-phase AC current, supplied to a DC motor 1, is rectified by a forward direction rectifying unit 2 and a reverse direction rectifying unit 3 while the rectifying units 2, 3 output a voltage, whose phase is controlled by phase controllers 39, 40, to control the speed of said DC motor 1. The regenerative braking control circuit of the DC motor 1 is constituted of a speed discriminator 9, discriminating a speed through a speed detector 20, a comparator 32, comparing through the current detector 31 of the input line 28 of the 3-phase AC current, first and second timers 35, 38, a logical operation circuit 33, having built-in timers 41, 42, a forward direction switch 14, a forward direction phase controller 39, a reverse direction switch 13, a reverse direction phase controller 40 and the like. The speed discriminator 9 is saturated either in positive or in negative upon normal operation and is saturated reversely upon regenerative braking, therefore, it is confirmed by the logical operation circuit 33 or the like, thereafter, the regenerative braking is effected.

Filed: 1989-11-01
Abstract: PURPOSE:To prevent the deterioration of the surface of the doubling layer under a cap layer in annealing by stacking the cap layer in contact with the doubling layer, and successively stacking a cap protective layer in contact with this cap layer. CONSTITUTION:Phosphorus, which adheres to the surface of a cap layer 6 in crystal growth, adheres to it at the time of cooling after crystal growth. Thereupon, after the cap layer 6 is stacked, successively a cap protective layer 7 is stacked in contact with the cap layer 6. By doing it this way, even if P drops off at the time of cooling, it adheres to the surface of the cap protective layer 7, and it does not adhere to the cap layer 6. Therefore, the surface of the cap layer 6 can be kept clean. The cap protective layer 7 is removed by selective etching after it has effected the role of keeping the surface of the cap layer 6 clean.
