摘要:
A thermal actuator comprises a substantially straight beam. The beam has a beam length and a beam mid-point. The beam comprises a plurality of beam segments with beam segment lengths. Each beam segment has a beam segment neutral axis, thus forming a corresponding plurality of beam segment neutral axes. The beam segment neutral axes are offset along the beam length based on a predetermined pattern. As the beam is heated by an included heating means, the beam buckles. The buckling of the beam, in turn, causes the beam mid-point to translate or move in the predetermined direction. The beam mid-point movement, in turn, operates an included optical waveguide switch. The heating means comprises any of Joule heating, eddy current heating, conduction heating, convection heating and radiation heating.

A thermal actuator comprises a substantially straight beam. The beam has a beam length and a beam mid-point. The beam comprises a plurality of beam segments. Each beam segment has a beam segment width, the beam thus forming a corresponding plurality of beam segment widths. The beam segment widths vary along the beam length based on a predetermined pattern. As the beam is heated by an included heating means, the beam buckles. The buckling of the beam, in turn, causes the beam mid-point to translate or move in a predetermined direction. The beam mid-point movement, in turn, operates an included optical waveguide switch. The heating means comprises any of Joule heating, eddy current heating, conduction heating, convection heating and radiation heating.

An actuator system that includes two beams that are formed into a diamond pattern. A crossbar is positioned at a midsection to connect the two beams. When power is applied to the two beams, the diamond pattern is driven vertically. An actuator system may also include a substrate and a first layer above a second layer on the substrate. The first and second layers include upper and lower beams joined together at one end of the layers. A method of forming an actuator system includes forming a first layer above a second layer on a substrate, joining the first and second layers together at one end of the layers, and forming upper and lower beams. The upper and lower beams may be different in width, length and thickness to control a vertical movement of the actuator system.

A thermal actuator comprises a plurality of substantially straight and parallel beams arranged to form a beam array. The midpoint of each beam is attached or coupled to an orthogonal coupling beam. Each array beam has a beam heating parameter with a corresponding beam heating parameter value. The beam heating parameter values vary across the beam array based on a predetermined pattern. As the beams are heated by an included heating means, the distribution of beam temperatures in the beam array becomes asymmetric, thus causing the beam array to buckle. The buckling of the beams in the beam array, in turn, causes the attached coupling beam to move in a predetermined direction. The coupling beam motion, in turn, operates an included optical waveguide switch. The beams in the beam array are heated by any of Joule heating, eddy current heating, conduction heating, convection heating and radiation heating.

A method for forming a gap (16) of a width (d) which meets selected tolerance limits includes forming sidewalls (80, 82) in a microstructure, the sidewalls defining a gap (16) therebetween. The gap has a width defined between the sidewalls. The width of the gap between the sidewalls is determined. Where the determined width of the gap is below the selected tolerance limits for the width of the gap, the sidewalls are consumed to form a gap which meets the selected tolerance limits. The gap may be incorporated in a waveguide device (10) of a microswitch (100) and selectively connect input and output waveguides (130, 132).

A method for bonding a polymer layer to an outlet plate for an inkjet print head has been developed that enables the polymer layer to be attached to the outlet plate with little or no bowing of the polymer layer. The method includes aligning recesses in a bonding plate with channels in an outlet plate, interposing a polymer layer between the bonding plate and the outlet plate, and pressing the bonding plate against the polymer layer to bond the polymer layer to the outlet plate.
