Abstract:
A THz photomixer emitter is disclosed. The emitter comprises a photoconductive material, an antenna structure, and an electrode array. The electrode array is disposed such that an electric field associated with photocarriers generated in the photoconductive material is coupled to the antenna for emission of a THz wave via the antenna structure. The electrode array is configured such that an electric field resonance pattern of the electrode array is substantially aligned with an emission field pattern of the antenna structure.

Abstract:
A printhead includes a jetting module that forms liquid drops travelling along a first path. A deflection mechanism causes selected liquid drops formed by the jetting module to deviate from the first path and begin travelling along a second path. A catcher includes a stationary porous surface. A liquid film flows over the stationary porous surface of the catcher. The catcher is positioned relative to the first path such that the liquid drops travelling along one of the first path and the second path contact the liquid film.
Abstract:
A unimodal polymeric resin having a density of from about 0.946 g/ml to about 0.97 g/ml and a zero shear viscosity of from about 8×102 Pa-s to about 6×104 Pa-s. A method comprising (a) providing a catalyst system comprising a half-sandwich transition metal complex; (b) contacting the catalyst system with an olefin under conditions suitable to form a polyolefin, wherein the polyolefin is unimodal; and (c) recovering the polyolefin, wherein the polyolefin has a density of from about 0.946 g/ml to about 0.97 g/ml and a zero shear viscosity of from about 8×102 Pa-s to about 6×104 Pa-s. A unimodal polymeric resin having a density of from about 0.946 g/ml to about 0.97 g/ml and a CY-a parameter of from about 0.5 to about 0.6.

Abstract:
A liquid dispenser includes a first liquid chamber and a second liquid chamber. The first liquid chamber includes a nozzle. A heater is associated with the second liquid chamber. A flexible corrugated membrane is positioned to separate and fluidically seal the first liquid chamber and the second liquid chamber from each other.
Abstract:
A liquid dispenser includes a liquid supply channel, a liquid return channel, and a liquid dispensing channel. The liquid dispensing channel includes a wall. The wall includes a surface. A portion of the wall defines an outlet opening. A drain is located in the wall downstream from the outlet opening. The drain includes a radius of curvature as viewed from a direction perpendicular to the wall. A liquid supply provides liquid that flows from the liquid supply channel through the liquid dispensing channel to the liquid return channel. A diverter member selectively diverts a portion of the flowing liquid through the outlet opening of the liquid dispensing channel.
Abstract:
A printhead includes a substrate, catcher, and monolithic liquid jetting structure including a nozzle and deflection mechanism. A liquid jet is ejected through the nozzle in a direction substantially parallel to a first surface of the substrate. The nozzle includes material layers formed on the first surface of the substrate. At least one of the material layers of the nozzle includes a drop forming mechanism actuated to form liquid drops from the liquid jet. The deflection mechanism is associated with the liquid jet and deflects portions of the liquid jet between first and second paths. The liquid drops formed from portions of the liquid jet following the first path and second path continue to follow the first path and second path, respectively. The catcher includes a liquid drop contact surface including a portion of the first surface of the substrate and collects liquid drops following the second path.
