Abstract: An apparatus for coating a photoreceptor substrate, such as a photoreceptor belt or a photoreceptor drum, consists of at least one photoreceptor coating fluid reservoir or diptank. The diptank defines an inlet at one end and a conduit with an orifice at the other end. The conduit includes at least one porous element such as a grid, screen or mesh arranged for suspending a plurality of layers of non-contaminating rounded objects, such as stainless steel or glass beads, in the bottom of the conduit. Photoreceptor coating solution supplied to the inlet is thereby forced to flow through the plurality of layers of beads prior to coating a photoreceptor substrate that is inserted through the orifice. As a result, the uniformity of the coating solution is improved as it coats the photoreceptor substrate, thereby reducing coating defects in the finished photoreceptor belt or drum.

The optical switching element is applicable in a device, a photoaddressable display medium and a display device. The optical switching element may alternatively include a mono-layered optical switching layer that has a charge generating function and a charge transporting function, wherein the mono-layered optical switching layer contains the charge transporting material represented by the following general formula (1).
Abstract: This invention relates to a toner for image formation that is used in developing an electrostatic latent image. In the toner of the present invention, an addition of a polyglycerol compound allows exhibiting an effect of dispersing a colorant in a water-repellent binding resin, thereby allows obtaining uniform dispersion by one-time kneading. Furthermore, since the degree of esterification of the polyglycerol compound is made 50% or higher and the degree of polycondensation n of polyglycerol is made from 9 to 30, even when the polyglycerol compound is added, the deterioration of electrostatic charging property and the filming can be prevented.

Abstract: By varying corona producing element height/projection, a more uniform charge potential is achieved. Elements, such as pins or teeth, are shorter at the edges of an element array and grow longer as one moves toward the center of the array. Such variation in height/projection overcomes shielding from adjacent teeth, as well as other effects, to yield the more uniform charging potential.

Abstract: An encased driving section includes magnets provided on a bottom surface in such a manner that their polarities are alternately oriented, a movable frame which is contained in the case and to which coils are attached, and an operating member fixed on the frame. When a state sensor unit senses a state of a vehicle or outside the vehicle, such as omission to turn off lights and the direction of wind, a control section determines whether or not the sensed state should be indicated to an operator and, when it determines that the information should be indicated, passes an electric current through the coils in a predetermined direction to drive the driving section in order to communicate the information to the operator through a haptic stimulus. The haptic interface device can communicate various information to the operator through their sense of touch.
