Title: A method of melting a rod of crystalline material zone-by-zone
IPC: C30B13/32
Filed: 1967-09-25
Abstract: 1,129,488. Floating zone-melting. SIEMENS A.G. 25 Sept., 1967 [24 Sept., 1966], No. 43613/67. Addition to 1044592. Heading BIS. In the zone-melting of a rod of silicon with lateral shifting of the holder for the recrystallized material, the holder shaft passes through an opening in the zone-melting chamber and is shifted by a moving carriage in hermetic contact with the outside of the chamber around the opening, abutment members being provided to limit movement of the carriage. The shaft passes through the carriage in known hermetic manner to enable rotary and axial movement of the shaft to be effected. The other holder may be similarly shifted. The chamber and carriage may have flat engaging surfaces, one of which has an annular groove containing oil or a resilient sealing ring. Alternatively, the chamber and carriage may be separated by concentric annular resilient walls forming an annular space to which oil is fed through the carriage. The shifting may be by linear or eccentric circular movement. The diameter of the recrystallized rod may be smaller, the same, or greater than that of the rod to be recrystallized.

Abstract: 1522817 Magnetic storage arrangements INTERNATIONAL BUSINESS MACHINES CORP 31 Oct 1975 [31 Dec 1974] 45263/75 Heading H3B A magnetic bubble domain BD, Fig. 2A, is moved by a pulsating in-plane magnetic field Hx along a path defined either by a permalloy or NiFe magnetic overlay 13 on the bubble supporting layer 10, or by an ion implantation pattern in the layer, the field imparting a forward extension and rearward contraction movement to the bubble. Thus leftward movement 14 is produced by a + Hx field acting in the direction shown, the field reducing the external bubble field 16 on one side of the bubble and augmenting the external field on the opposite side. Continuity of movement is produced by using a sawtooth pulsating field, Figs. 2B and 2C, having different rise and fall times, the positive and negative waveforms shown imparting leftward 14 and rightward 14<SP>1</SP> bubble movements, respectively. Alternatively the pulsating field may have different positive and negative durations, Fig. 2D, and/or different amplitudes. The path defining overlay may be in the form of individual strips 18A, 18B, Fig. 3, extending between respective bubble generators G1, G2 and magnetoresistive sensors 20A, 20B. In a modification, Fig. 4 (not shown), the paths are formed by ion implantation strip regions. An alternative arrangement is described, Fig. 5B, in which the bubble layer 10 is overlaid by a magnetic strip 32 and an angel fish pattern 34, bubble movement being effected by an in-plane rotating magnetic field which reacts with the angel fish pattern to produce the required bubble expansions and contractions.
