A print head die () includes slot ribs () having edges () with triangular notches. In one embodiment, the print head die is formed by dry etching from a first side () of a wafer () a series of spaced openings () completely through the wafer () and separated by ribs () followed by wet etching the wafer () from a second opposite side () to recess the ribs () from the second side ().

Print head slot ribs

An adhesive joint with an ink trap is provided. The joint may be employed in a cartridge for an inkjet printer. The cartridge includes a headland region attached to a printhead assembly by an adhesive layer. The adhesive joint between the headland region and the printhead assembly include notches for retaining additional adhesive in order to reduce degradation of adhesive due to ink penetration. A method of assembling the printer cartridge to include an ink trap in the adhesive joint is also provided.

An apparatus includes a first member, a second member and a flexure. The flexure has a central portion connected to the first member, outer portions connected to the second member and an intermediate portion spaced from the first member and the second member.

Flexure

An electron beam actuated light modulator, including an actuatable mirror element carried by a pedestal and hinge portion, having an electrostatically more neutral first position and an electrostatically more charged second position, the mirror being actuatable in a first direction from the first position to the second position by charge accumulation, and is actuatable in a second direction from the second position to the first position by dissipation of the charge accumulation and a stop element positioned adjacent the mirror element in the first position, configured to limit movement of the mirror element in the second direction after the mirror reaches the first position traveling in the second direction.
