Title: An automatically controlled process for melting a rod of semi-conductor material zone-by-zone
IPC: C30B13/30
Filed: 1960-06-17
Abstract: <PICT:0899688/III/1> <PICT:0899688/III/2> In the zone-refining of a rod by passing an induction heating coil over the rod, the diameter of the molten zone is controlled at a desired value at a particular point in its passage by utilizing deviation in the strength of the current passing through the coil from a predetermined value corresponding to the desired diameter to compress or draw apart the two ends of the rod.  The molten zone may be passed upwards at a constant speed through a vertical rod after passage through a seed of smaller diameter fused to the rod under such conditions that the difference in diameter is maintained.  The portion of the rod below the molten zone may be rotated.  As shown in Fig. 1, a variable high frequency generator 9 feeds a heating coil 5 having a capacitor 7 in parallel therewith and relative movement is effected between the coil and a rod 2 by means not shown.  The generator has a discharge device (not shown) which produces an anode current and a voltage drop across a variable resistance 13 connected in series opposition to a battery 14.  On variation of the rod diameter from a desired constant value, variation in the anode current operates polarized relay 15 which causes electric motor 17 to effect upward or downward movement of rod holder 4 through the medium of toothed wheel 18 and toothed rack 19 to counteract the variation.  As shown in Fig. 4, the generator frequency and heater current are varied in accordance with the preset programme illustrated in Fig. 3 (not shown) to maintain a seed crystal of reduced diameter, continuous upward movement of heating coil 5 being effected by electric motor 116 through the medium of toothed wheel 115, toothed rack 114, and insulated carrier 113, electric motor 116 at the same time effecting continuous rotation of current wipers 128 and 129 relative to a series of capacitors 125 and a voltage divider 131 respectively to effect variation in frequency and current respectively.  Specification 888,148 is referred to.

Abstract: 674,931. Control of A.C. motors. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. S. July 21, 1949. [Aug. 23, 1948] No. 22188/48. Class 38 (iii). A wound rotor induction motor is arranged for forward motoring and at least one other operational state such as reverse power braking or dynamic braking, a control member selects the operational state, variable resistance is arranged to be connected to one winding of the motor, and a servo-motor is arranged to vary the magnitude of the resistance. A main contactor and a pilot contactor is provided for each operational state in addition to an interlock contactor. The pilot contactors are arranged to be energized selectively by the control member but the energization of the associated main contactor is dependent upon the state of the interlock contactor which is arranged to be energized or de-energized in dependence upon the magnitude of the resistance, the arrangement of the interlocking means being such that, on changing from one operational state to another, the current-supply to the motor for the second operational state is not connected until the resistance is not less than a predetermined value. When a control lever 16 is returned to the neutral position to terminate forward motoring operation of an induction motor forming part of the equipment described in Specification 674,932, contacts 13 open to de-energize a pilot contactor 6 which then closes contacts 37. The pilot contactor de-energizes a main contactor 3, but the opening of contacts 34 is delayed, and, if the rotor resistance is not adjusted to its maximum, or other pre-determined value, an interlock contactor 25 is energized from an alternating-current source 12 through contacts 33. When energized, the interlock contactor closes self-maintaining contacts 40 and opens contacts 24, energization of forward contactor 3 or reverse braking contactor 4 being prevented until the contacts 33 open upon the rotor resistance being adjusted to its pre-determined value. Similar operation is afforded after operation through the reverse braking contactor 4 or the direct-current braking contactor 5. However, direct-current braking may be introduced with the rotor resistance at less than its pre-determined value. When the contactors 3, 4 or 5 are open the restraining and control windings referred to in the above Specification are de-energized, so that the rotor resistance is adjusted to take up its maximum, or other pre-determined value, under the effect of the bias upon the valve member.
