摘要： A new data storage device that includes one or more digital data storage elements, each element including a magnetic core, and an input addressing portion comprising a magnetic input addressing element for receiving at an input magnetic flux representing a data value and selectively coupling a flux to an output for transmission to a magnetic core in response to addressing flux generated therein. An output element magnetically coupled to a magnetic core detects transitions in magnetic flux in a magnetic core. In addition, the data storage element may further comprise an output addressing portion comprising a magnetic input addressing element for receiving at an input magnetic flux representative of flux in a magnetic core and selectively coupling a flux to an output in response to addressing flux generated therein.

摘要： A read head for a Wiegand wire has an E-core with a pick-up coil for the "1" bit wound on one outer leg and a separate pick-up coil for the "0" bit wound on a second outer leg. The E-core is composed of a relatively thin ferromagnetic E-laminae spaced from a relatively thick E-laminae. Between thin and thick laminae in each leg there is an appropriately polarized magnet. The result is to establish a first field across the face of the read head between the center leg and a first outer leg. This first field reads the one bits. Similarly, a second field between the center leg and the other outer leg reads the zero bits. Each one bit wire is on one side of the code strip and each zero bit wire is on the other side of the code strip so that the one bit and zero bit wires are passed respectively across the first and second reading fields provided by the read head. Saturation of the thin E-laminae and non-saturation of the thick E-laminae assures that the field configuration is appropriate to set and switch the Wiegand wires.
摘要翻译： Wiegand线的读头具有E型芯，其具有用于在一个外腿上缠绕的“1”位的拾取线圈和用于在第二外腿上缠绕的“0”位的单独拾取线圈。 E型芯由相对薄的铁磁E层组成，与相对较厚的电子层间隔开。在每条腿之间的薄薄层之间有一个适当的极化磁体。结果是在中心腿和第一外腿之间的读头的表面上建立第一场。第一个字段读取一位。类似地，中心腿和另一个外腿之间的第二场读取零位。每一个位线在编码条的一侧上，每个零位线都在编码条的另一侧，使得一位和零位线分别通过读头提供的第一和第二读取字段。厚电子薄层的饱和度和厚电子层的不饱和度确保了现场配置适合设置和切换韦根电线。

摘要： A coupling arrangement for coupling laddics in cascade comprises an emitter follower transistor circuit arranged so that the output impedance of the transistor restricts the rise and fall times in the mmf of the laddic output winding. The effect is to reduce the risk of spurious reset signals being generated in the output winding of sufficient amplitude to reset the next laddic in the cascade.

摘要： A magnetizable fluid which serves as a display liquid and which includes a suspension of colloidal magnetic particles is used in a display device. The magnetic fluid is opaque to provide optical contrast. A host liquid is substantially immiscible with the display liquid. The display liquid is carried in a reservoir section which is distributed about the periphery of a display field in the reservoir. Each propagation line of the display field is provided with a bubble generator, which passes bubbles by the input end of each line. A bubble switch coil draws selected bubbles across a gap to reach the associated propagation line in response to a signal impressed on the coil. A uniform rotating magnetic field is provided by a permanent magnet beneath the display or by orthogonal magnetic coils.
