    摘要： Magnetic bubble domain memory circuit in which magnetizable overlay patterns of magnetically soft material, e.g. permalloy, are provided as bubble propagation elements on a bubble-supporting magnetic layer to define major and minor bubble propagation paths. The bubble propagation elements are arranged to form major propagation paths defining a bubble input section and a bubble output section respectively. A plurality of minor propagation paths in the form of closed storage loops defining a bubble storage section are disposed between the input and output bubble sections, being arranged in even and odd blocks of minor propagation paths. Input swap transfer gates and output replicate gates are provided between the bubble storage loops and the input and output sections respectively. The input swap transfer gates and the output replicate gates are of double level construction, each type of gate including a hairpin element at the first level and a 90.degree. hook-like element at the second level which is correlated into bubble propagation elements included in a minor storage loop. The 90.degree. hook-like elements of corresponding swap transfer and replicate gates are respectively situated at the input and output ends of the minor storage loops, forming the opposite bights of the loop. Bubble generators and detectors are associated with the input and output bubble sections respectively at the opposite ends of the minor storage loops to provide a magnetic bubble domain memory chip for data processing purposes. Data as represented by the presence or absence of a magnetic bubble is transferred into the minor storage loops and replicated outwardly therefrom into the bubble output section for detection in a manner enabling such data to be received by the bubble detector for readout at the field rate.

    摘要： Input swap transfer/replicate gate and output replicate gate for use in a magnetic bubble memory arrangement between the bubble storage loops and the input and output sections respectively on opposite sides thereof. The input swap transfer/replicate gate and the output replicate gate are of double level construction, each type of gate including a hairpin element at the first level and mounted on a planar layer of bubble-supporting magnetic material on which bubble propagation elements of magnetically soft material are disposed. The bubble propagation elements are arranged to form propagation paths defining a bubble input section, a bubble output section, and a plurality of closed storage loops defining a bubble storage section interposed between the input and output bubble sections. The second levels of the swap transfer/replicate gate and output replicate gate are situated at the input and output ends of the storage loops, forming the opposite bights of the loop. Each type of gate at the second level comprises an asymmetric hook-like transfer/replicate element whose opposite ends are respectively disposed in the opposite courses of the storage loop of which it forms a bight. The hook-like element includes an intermediate leg portion thereof disposed in overlapping relation to the loop region of the hairpin element, the intermediate leg portion being of wedge-shaped configuration and tapering toward the leading end of the asymmetric hook-like transfer element so as to have a reduced width dimension at the leading end thereof. The wedge-shaped configuration of the intermediate leg of the asymmetric hook-like element is responsible for greater reliability in data transfer and replication as represented by bubbles and the absence of bubbles into and out of the storage loops of the magnetic bubble memory organization.

    摘要： Method of fabricating a magnetic bubble memory device in which the magnetizable upper overlay pattern of magnetically soft material, e.g. permalloy, defining bubble propagation elements and bubble function-determining components as located above a bubble-supporting magnetic film is disposed in a wholly planar configuration to avoid bubble propagation anomalies encountered with typical non-planar overlay patterns of magnetically soft material. The fabrication method provides for the consecutive deposition onto a substrate having a magnetic film capable of supporting magnetic bubbles of a layer of non-magnetic electrically conductive material, a layer of insulating material, and a layer of magnetically soft material, such as permalloy. Patterning of the layers then proceeds from the uppermost layer downwardly in stages to form magnetically soft components defining the elements of magnetic bubble propagation paths and magnetic bubble function-determining components as a planar upper overlay pattern from the layer of magnetically soft material, insulation spacers from the layer of insulating material, and control conductors as a planar lower overlay pattern from the layer of non-magnetic electrically conductive material. Patterning of the respective layers is preferably achieved by ion milling of selected portions of the layer of magnetically soft material as defined by a first mask and by sequential plasma etching of selected portions of the underlying layer of insulating material and the layer of non-magnetic electrically conductive material as defined by a second composite mask partially comprising the overlay pattern of magnetically soft material and photoresist material.

    摘要： An apparatus for slicing apples is provided. The slicer utilizes thinner blades than known in the art, with a thickness less than 300 microns, and preferably between 180 and 220 microns. Each of the thinner blades is supported against bending, warping or twisting by a novel clinch buckle which rigidly supports the outer end or ends of each blades. The clinch buckle is rigidly connected to bent tabs formed at the outer end or ends of each blade and supports the outer ends across the full width of the blades. The clinch buckle is supported by an outer blade support ring and is captured by the outer support ring to prevent rotation of the clinch buckle. The thinner blade reduces cell damage, reduces the amount of sealant or neutralizer needed to slow or prevent oxidation of enzymes released from cells ruptured by slicing, and delays the onset of browning. A serrated blade is used to further reduce the extent of cell damage.
