摘要： A rotating element for use in an electric paper system in which the rotating element may be either substantially cylindrical or substantially spherical in shape and comprises at least three portions. Each portion has an associated optical modulation characteristic and the optical modulation characteristics of at least one portion are different from the optical modulation characteristics of at least one other portion. One of the portions is capable of being permanently magnetized. The rotating element also has an anisotropy for providing an electrical dipole moment. The electrical dipole moment renders the element electrically responsive such that when the rotating element is rotatably disposed in an electric field while the electrical dipole moment of the rotating element is provided, the rotating element tends to rotate to an orientation in which the electrical dipole moment aligns with the field.

摘要： A method of making rotating element sheet material utilizing magnetic latching is disclosed. First a plurality of rotating elements, each element having a magnetized segment, are mixed with an elastomer and a plurality of magnetic particles to attract the magnetic particles to the magnetized segments. Then a magnetic field is applied to orient the elements in a common direction. When the rotating elements have all been oriented in a common direction, they are held in that orientation for a long enough period of time to allow the magnetic particles to migrate in the elastomer to the regions of the elastomer in the vicinity of the magnetized segments of the elements. The elastomer is then cured to form an elastomer substrate with trapped rotating elements and magnetic particles. The elastomer substrate is then immersed into a bath of dielectric plasticizer which is absorbed more readily by elastomer than by the rotating elements. The elastomer substrate swells to create plasticizer-filled voids around the rotating elements. The magnetic particles remain incorporated within the elastomer to form magnetic material pads which are associated with an element.

The apparatus comprises at least one separator member. Each separator member has a diameter, two opposed surfaces and an edge region in contact with both of the surfaces. Further included is an apparatus for providing at least two liquid flows wherein each one of the liquid flows has an associated separator member and an associated surface on the associated separator member, and each one of the liquid flows is provided across the associated surface of the associated separator members. The liquid flow flows toward the edge region of the associated separator member. The liquid flows are each a flow of hardenable liquid material associated with an optical modulation characteristic, and at least one of the liquid flows containing a magnetic pigment. The separator members are spun and the liquid flows are merged outboard of the edge regions of the one separator members to form a reservoir containing side-by-side amounts of each liquid. When the flow rate of the liquids is high enough, a free jet approximately in a plane outward from the reservoir, the free jet comprising side-by-side amounts of each liquid from the reservoir is formed. A magnetic field, is provided outward from the formation of the free jet and at least a portion of the free jet is passed through the magnetic field to magnetize the magnetic pigment. The magnetic field is aligned transverse to the free jet. If cylindrical elements are desired then the magnetized free jet is hardened into filaments which can be separated into cylindrical elements. If spherical elements are desired then the free jet is broken up into spherical elements before hardening.

摘要： A method of making rotating element sheet material utilizing magnetic latching is provided. The first step is providing a sheet of sheet material comprising a substrate with a surface and rotatable elements disposed therein. The elements each have an optical and electrical anisotropy, and comprise at least two portions. One of the portions is magnetizable. After the magnetizable portions have been oriented in a common direction, they are magnetized substantially uniformly. The elements can be oriented such that the magnetized portions are disposed towards the surface of the substrate. A layer of hardenable mixture containing a plurality of magnetic particles is then applied to the surface of the substrate. The hardenable liquid is kept liquid for a period of time to allow the migration magnetic particles to the area of the layer in the vicinity of the magnetized portions of the rotatable elements. Then the hardenable liquid is solidified to trap the magnetic particles in said layer in the area of the layer in the vicinity of the magnetized portion of the rotatable elements to form a magnetic pad.

摘要： A method of forming magnetized rotating elements for a rotating element display where all the elements are magnetized in the same orientation is provided. First, at least two planar streams of hardenable liquids flowing in substantially the same direction are provided. Each stream has an associated optical modulation characteristic and at least one stream has an associated optical modulation characteristic different from at least one other stream. At least one stream includes a magnetic pigment. The streams are then merged to form a reservoir containing side-by-side amounts of each liquid from each stream. A free jet is then formed containing side-by-side amounts of each liquid from the reservoir. Then a portion of the free jet is passed through a magnetic field which is oriented transverse to the direction of the free jet to magnetize the magnetic pigment. The rotating elements formed can be either spherical in shape or cylindrical in shape. In either case, each element will be comprised of side-by-side segments. To form spherical elements the free jet can be broken into spherical portions either before or after the magnetic pigment has been magnetized. Ultimately, magnetized spherical portions of the free jet are hardened into rotating spherical elements and collected. To form cylindrical elements, the free jet is magnetized and hardened into a filament The filament is then collected and broken into cylindrical elements.

摘要： An electric type paper display having memory properties, rapid response times and multi-optical property display with an image of high quality is made. Each display element is wholly in contact with liquid in a cavity and the surface of each display element has a portion with a most positive charge. When an electrical field is applied from the outside, each display element is turned correspondingly to the direction of the electric field and, then electrically migrated through the liquid and attached to the inner surface of the cavity. Among multiple display surfaces of each display element an optical property is selected according to an image signal and is visible through a transparent support to an observer. Afterwards, the attached state of each display element, i.e., its display state is held by the action of an attraction force such as van der Waals force and electrostatic force acting between the circumferential surface of the display element and the inner surface of the cavity, even after the electric field is removed.
