    Abstract: An apparatus for fabricating hemispherically bichromal balls, comprising a separator member (38) having opposing first and second surfaces (34,36) and an edge region (40) in contact with both surfaces, and delivery means for flowing first and second colored hardenable liquid material over the first and second surfaces, respectively, so that the liquid materials arrive at the edge at substantially the same flow rate and form a reservoir (42) outboard of the edge region (40). The reservoir comprises side-by-side regions (44,46) of liquid materials of different colors which do not intermix. Further means is provided for propelling the first and second liquid materials away from the separator member and out of the reservoir into a fluid medium as a plurality of side-by-side bichromal streams (48) whose forward ends become unstable and break up into droplets (10) which form into spherical balls, each of the balls comprising hemispheres of differently colored hardenable liquid, and means for collecting the bichromal balls.

    Abstract: Disclosed are ionographic imaging apparatuses and processes. One apparatus comprises an imaging means (1), means (5) for applying to the imaging means a liquid material capable of forming a dielectric peel layer adhering to the imaging means, ionographic writing means (7) for generating a latent image on the peel layer, means (9) for developing the latent image on the peel layer, and means for simultaneously transferring the peel layer bearing the developed image from the imaging means to a substrate (15) and affixing the peel layer bearing the developed image to the substrate. In another embodiment, the apparatus employs a process which comprises applying to an imaging means a liquid material capable of forming a dielectric peel layer adhering to the imaging means, forming a first latent image on the peel layer with an ionographic writing means, developing the first latent image with a first developer, forming a second latent image on the peel layer containing the first developed image with an ionographic writing means, developing the second latent image with a second developer, forming a third latent image on the peel layer containing the first and second developed images with an ionographic writing means, developing the third latent image with a third developer, and simultaneously transferring the portion of the peel layer that bears the developed images to a substrate and affixing the peel layer bearing the developed images to the substrate. A further embodiment is directed to an apparatus and process for sequentially forming and developing primary color images on an imaging means to form a full color image, followed by transferring the fully formed image to a substrate, wherein the developers employed contain a release agent.

    Abstract: PROBLEM TO BE SOLVED: To provide a system and a method for jetting a fluid which have improved performance characteristics. SOLUTION: A piston arrangement 110 is set movably to the inside of a fluid small chamber 120. A movement of the piston arrangement 110 towards a static face plate 130 presses a part of a fluid 140 between the piston arrangement 110 and the static face plate 130 to the outside from a nozzle hole 132 of the static face plate 130, whereby droplets or a jet of the fluid 140 is formed. A viscous force generated by a flow of the fluid along an action surface of the piston arrangement 110 moving towards the nozzle hole 132 or away from the nozzle hole 132 generates a force resisting to the movement of the piston arrangement 110. The resistance force tends to decelerate the movement of the piston arrangement 110 and to prevent the piston arrangement 110 from touching the static face plate 130. The fluid small chamber 120 is constituted of a cylinder arrangement in various embodiments.

    Abstract: PROBLEM TO BE SOLVED: To actualize a closely charged single-layer gyricon display which can have its surface coating rate approximated to 100% without using any space particle by using not spherical dichroic elements, but cylinder elements. SOLUTION: The projection area of cylinders 51 on the plane of a surface 55 is so determined that the entire plane area of the surface 55 is covered as much as possible. Cavities 53 are formed preferably as small as possible and ideally as large as the cylinders themselves. The larger the ratio of the total projection area of the cylinders on the lane of the observation surface 55 and the total area of the observation surface 55 is, the more the reflection degree and luminance of the observation surface 55 are improved. The maximum surface coating rate which is logically possible with spherical diachronic balls by conventional technology is about 90.7%, but the maximum value regarding the dichroic cylinders in this case is 100%. Therefore, the gyricon display formed of a single layer of closed charged cylinders can have the luminance made larger than that of a gyricon display formed of a single layer of closely charged spherical balls by the conventional technology.

    Abstract: PROBLEM TO BE SOLVED: To provide fluid ejection system and method having improved performance characteristics. SOLUTION: A fluid ejector 100 comprises a movable piston constitution 110 and a stationary face plate 130. A small fluid chamber 120 is formed between the piston constitution 110 and a substrate 150. The piston constitution 110 is fixed resiliently to the substrate 150 by means of one or more spring component 114. Ejected fluid 140 is supplied from a fluid storage unit the small fluid chamber 120 through a fluid supplement hole 152 made in the substrate 150. The stationary face plate 130 has a nozzle hole 132 for ejecting a fluid jet or a droplet. The piston constitution 110 is moved toward the stationary face plate 130 by electrostatic attraction between the piston constitution 110 and the stationary face plate 130, and a part of fluid between the piston constitution 110 and the stationary face plate 130 is pushed out from the nozzle hole 132 to form a jet or a droplet.

    Abstract: PROBLEM TO BE SOLVED: To provide a method for efficiently starting an apparatus being driven electrostatically. SOLUTION: An electric drive system applies a drive signal 152 to an apparatus being started electrostatically such that a resulting electric field has a constant force. The electric drive system applies the drive signal 152 to a fluid ejector 100 being started electrostatically wherein the fluid ejector 100 comprises a piston 120, and a face plate 140 having an ejection nozzle 142. Ejected dielectric fluid is supplied between the piston 120 and the face plate 140. The drive signal 152 is applied to one of the piston 120 or the face plate 140 and causes to generate an electric fluid traversing the fluid between the piston 120 and the face plate 140. The electric field attracts the piston 120 electrostatically toward the face plate 140 and a jet or a droplet of fluid is ejected through the ejection nozzle 142.
