摘要： A motor based on the wobble motor provides pure rotary motion and can be used as a spindle motor for very small disk drives. The primary components of the motor are fabricated using thin film processes. The rotor has inner and outer rings that are interconnected by flexible members, such as semicircularly-shaped spring elements, with the rings and flexible members being formed of the same material. The rotor resides within the wobble motor stator elements that are circumferentially spaced on a substrate. The inner rotor ring is supported by a bearing structure that may be a ball bearing assembly or a pin bearing comprising a post and a restraining cap. The outer rotor ring functions as the wobble motor rotor and rolls around the inside of the stator as the stator elements are sequentially electrostatically activated. The flexible members act as a transmission to convert the wobble motion of the outer rotor ring to pure rotary motion of the inner rotor ring. The motor can function as a disk drive spindle motor by attachment of a data recording disk to the inner rotor ring and use of appropriate control circuitry to drive the motor at constant speed. The disk drive actuator may be attached to the same substrate that supports the stator elements. The stator elements, the rotor, and the bearing assembly may all be fabricated on a suitable substrate using thin film processes, without the necessity of assembly of separate components.

摘要： In the fabrication of a free-standing miniaturized structure in a range of about 10 to 20 .mu.m thick, a method based on a sacrificial system includes the steps of selecting a substrate material, depositing on the substrate material a sacrificial layer of material and patterning the sacrificial layer to define a shape. A photoresist layer of material is deposited on the sacrificial layer and patterned by contrast-enhanced photolithography to form a photoresist mold. Upon the mold there is plated a metallic layer of material. The electroplated structure conforms to the resist profile and can have a thickness many times that of conventional polysilicon microstructures. The photoresist mold and the sacrificial layer are thereafter dissolved using etchants to form a free standing metallic structure in a range of about 10 to 20 .mu.m thick, with vertical to lateral aspect ratios of 9:1 to 10:1 or more.

摘要： An information storage device which stores a single flux quantum without bias is disclosed. The device includes a single Josephson tunneling device made from two superconductive materials spaced apart by an insulator wherein a Josephson current density profile J.sub.1 (x) defined by ##EQU1## IS CHARACTERIZED SUCH THAT THE PROFILE HAS A LARGER MAGNITUDE AT THE BOUNDARY PORTIONS OF SAID DEVICE THAN AT THE CENTER. The current density profile is controlled by adjusting either the oxide thicknesses, the work function of the superconductors or by changing the shape of the junction from its usual rectangular cross-section.A sensing arrangement for the above described storage devices is also disclosed. By controlling the damping of the above described structures, the gain characteristics and the vortex characteristics are adjusted to permit coincident selection of a single device. The overall reduction in the magnitude of the Josephson current density profile provides a higher junction resistance with a consequent decrease in damping. This increase in resistance across the tunneling junction unexpectedly extends the switching characteristic from the envelope boundary of all vortex modes to the extent that the application of the same coincident currents permits the unambiguous reading of both positive and zero or negative vortices. Each device during sensing acts as its own sense detector and is capable of switching to the voltage state if a flux quantum is stored. A bit-organized memory array utilizing the devices disclosed is also shown.

摘要： A Josephson logic network which includes high and low transmission line impedance sections in the feeder line enables multiple logic devices to be connected in series to the same feeder line with minimum crosstalk between the logic devices. Also, the arrangement of the high and low impedance sections results in resetting of a switched Josephson logic device without the need for altering the d.c. current supplied to the feeder line.

摘要： Josephson tunneling devices are used as parametrons in circuits for logic and memory. Parametron circuits are used as input devices to conventional pulsed Josephson tunneling device circuitry, and as output devices from pulsed Josephson tunneling device circuitry. Therefore, transfers from phase information to pulse information and from pulse information to phase information are obtained. Interconnection between superconducting circuit chips is achieved using Josephson tunneling parametrons and Josephson tunneling detectors. Another interconnection scheme uses capacitive coupling between superconducting circuit chips without physical interconnections therebetween, and employs Josephson tunneling devices on separate chips for the receiving and sending circuitry.
