Various structures, such as microstructures and wall-like structures, can include parts or surfaces that are oblique. In some implementations, a cantilevered element includes a spring-like portion with a uniformly oblique surface or with another artifact of an oblique radiation technique. In some implementations, when a deflecting force is applied, a spring-like portion can provide deflection and spring force within required ranges. Various oblique radiation techniques can be used, such as radiation of a layer through a prism, and structures having spring-like portions with oblique radiation artifacts can be used in various applications, such as with downward or upward deflecting forces.
摘要:
An electrophoretic-type display device including an array of microcells, where each microcell is formed by a microwell containing a quantity of ink and a polymer-based membrane connected to upper edges of the microwell. The membrane is formed by curing an aqueous or hydroalcoholic sealing solution that is overcoated on the ink-filled microwells. The ink includes an isoparaffinic-based or oil-based suspension fluid, and the peripheral side walls of the microwell have a surface energy in the range of 20 to 30 mN/m. The microwell material serves two purposes: to prevent displacement (floating) of the relatively light ink solution above the relatively heavy sealing solution, and to facilitate reliable attachment between the polymer membrane and microwell walls during subsequent curing.

A microfabricated light collimating screen is provided. A microfabricated screen, in one form, is made from a photopolymer such as SU-8 material. It is able to collimate light in two dimensions and for improved degrees of collimation. It may also be directly patterned onto image sensors or light sources in order to achieve direct collimation. The fabrication method is large-area compatible and inexpensive. The proposed screens may be useful for position detection of objects, such as in the paper mover, in printers and copy machines.

A print structure includes a pattern layer that selectively actuates one or more of a plurality of actuators to selectively form one or more wells in a print surface to create a defined pattern on the print surface. A material is applied to the one or more wells and subsequently transferred to another surface in order to transfer the pattern.

An electrical interconnect device attaches electrical devices with a cantilever spring with out the use of solder or adhesive. The cantilever spring latches to a contact structure such that there are a plurality of contact points between the spring and the contact structure. The cantilever spring has two tines at a tip end that define an opening in the spring. The contact structure is received by the opening between the two tines so that the spring and the contact structure mate. The spring may engage the contact structure by latching to the contact structure or by a post that urges the tip end of the spring against the contact structure.

In a ballistic aerosol marking device or the like, marking material flows from a material reservoir to a delivery channel via a port. The walls of the channel and or the port may be provided with a non-wetting coating to allow for control of the position of a meniscus formed in or at the port. By controlling the meniscus location, attributes of the system, such as the quantity of marking material delivered to the channel, the size of the marking material droplets delivered to the channel, the amount of foreign material (e.g., carrier liquid) delivered to the channel with the marking material, the field strength of gating electrodes, etc. may be controlled.

Methods are disclosed for applying a dampening fluid to a reimageable surface of an imaging member in a variable data lithography system without a form roller. Dampening fluid in liquid form is converted to vapor phase, and directed to the reimageable surface. The dampening fluid reverts to the liquid phase directly on the reimageable surface. Controlling the temperatures of elements of the delivery subsystem prevents unwanted condensation of the dampening fluid vapor on those elements. Generation and delivery of the vapor can be controlled in a feedback arrangement as a function of measured layer thickness formed on the reimageable surface to obtain a desired dampening fluid layer thickness formed on the reimageable surface.

A system and corresponding methods are disclosed for applying a dampening fluid to a reimageable surface of an imaging member in a variable data lithography system, without a form roller. In one embodiment, the system includes subsystems for converting a dampening fluid from a liquid phase to a dispersed fluid phase, and for directing flow of a dispersed fluid comprising the dampening fluid in dispersed fluid phase to the reimageable surface. The dampening fluid reverts to the liquid phase directly on the reimageable surface. In another embodiment a continuous ribbon of dampening fluid may be applied directly to the reimageable surface. This embodiment includes a body structure having a port for delivering dampening fluid in a continuous fluid ribbon directly to the reimageable surface, and a mechanism, associated with the body structure, for stripping an entrained air layer over the reimageable surface when the reimageable surface is in motion.
