International Classification:

G11C 1908

US Classification:

365 2

Abstract:

A unique and compact open coil rotating magnetic field network structure to efficiently package an array of bubble domain devices is disclosed. The field network has a configuration which effectively enables selected bubble domain devices from the array to be driven in a vertical magnetic field and in an independent and uniform horizontal rotating magnetic field. The field network is suitably adapted to minimize undesirable inductance effects, improve capabilities of heat dissipation, and facilitate repair or replacement of a bubble device.

Appl. No.:

5/708806

Inventors:

Thomas T. Chen - Yorba Linda CA

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

G11C 1908

US Classification:

365 1

Abstract:

This invention relates to an improved network and technique for correcting bubble domain memories of the major/minor loop type. In particular, a selectively insertable correction loop can be provided in a major loop path to insert or remove blank bits so that the effect of defective minor loops can be overcome. The correction networks include propagation loops formed of conventional magnetic bubble domain device elements and a conductor which is selectively alterable to provide a bypass or insertion mode of operation for the correction loop relative to the major loop.

International Classification:

C02F 102

C05F 900

US Classification:

71 11

Abstract:

The present invention provides a waste treatment process and device thereof which can reduce the size and weight of organic waste by decomposing the waste to powder form and bacteria free substance that may be used as a kind of fertilizer for plants. The waste is first frozen by liquefied nitrogen in a cooling chamber to a temperature less than -200. degree. F. , wherein during this freezing procedure, the gas generated from the waste must be removed from the cooling chamber. Then, the frozen nitrogen is immediately transferred to a heated chamber having a temperature of at least 160. degree. F. but not exceed 200. degree. F. During this heating procedure, the water content of the waste is sucked out of the heated chamber, so that the waste is decomposed to form the bacteria free powder.

Inventors:

Thomas T. Chen - Yorba Linda CA

Assignee:

Rockwell International Corporation - El Segundo CA

International Classification:

G11C 1908

US Classification:

365 16

Abstract:

A magnetic bubble domain circuit which permits the information in two separate propagation paths to crossover each other without deleterious effects. The crossover junction includes at least two definable propagation paths, a merge device for joining the paths, and an active transfer junction between the two paths. The information on the two paths is arranged to become interleaved or intermixed at the merge and to be separated at the active transfer switch arrangements are made for crossing over a plurality of propagation paths by using information properly timed or spaced, or, in the alternative, using a multiple junction arrangement.

International Classification:

G11C 1908

US Classification:

Abstract:

A large capacity bubble memory device using a basic major-minor loop storage cell design. The basic storage cell is repeated, typically in matrix form, on a suitable bubble domain structure. The cell design is arranged so that interconnecting elements between respective cells permit magnetic bubble domains to be selectively transferred between cells in accordance with the status of switch elements. Control signals control the switch status. The cells include redundancy features so that cells can be interconnected to form a large capacity storage loop whereby chip yield is increased.
