Abstract:
PROBLEM TO BE SOLVED: To provide a buckling beam switch movable between two states. SOLUTION: A substantially linear beam of a non-buckling state is compressed so that the beam is buckled and deformed by using an adjustable compressor. The compressor applies force to one end or both ends of the beam and limits compression amount applied to the beam so that the beam may be movable between a first buckling state and a second buckling state. The first buckling state and second buckling state are constituted of operations having substantially equal buckling deformation amount and buckling and deforming in an opposite direction from the non-buckling state.

PROBLEM TO BE SOLVED: To provide an actuator which is used in an optical waveguide switch. SOLUTION: A thermal actuator 500 is formed with a substantially straight beam 510. The beam 510 is formed with a plurality of beam segments 520, 522 and 524. The beam segments 520, 522 and 524 have predetermined beam widths 525, 526 and 527, respectively. The beam widths 525, 526 and 527 vary according to a predetermined pattern along the longitudinal direction 518 of the beam 510. The beam 510 buckles when heated with a built-in heating means 528 and 546, the intermediate point 519 of the beam moves toward a predetermined direction 548 due to the buckling of the beam, and a built-in optical waveguide switch is operated by the movement of the intermediate point 519 of the beam. The built-in heating means are realized by a Joule heating, an eddy current heating, a conduction heating, a convection heating, a radiation heating or the like. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract:
PROBLEM TO BE SOLVED: To solve the problem that in printed MEMS requiring materials to be jetted in liquid form from an inkjet printer, a structural material is likely to be a polymer, but the polymer is not conductive, normally, and although conductive polymers are available, these materials tend to have a high resistance. SOLUTION: The method is for creating a composite material for micro-electro mechanical systems. The method includes determining a layout for a micro-electro mechanical system device and alternating depositing drops of polymer and drops of conductor to create an interwoven matrix based on the layout. The method also includes the step of forming the micro-electro mechanical system device based on the layout. COPYRIGHT: (C)2009,JPO&INPIT

SOLUTION: A projection system includes a display apparatus comprising a plurality of tunable Fabry-Perot filters, each of the filters being configured for shifting between a state in which the filter transmits radiation in a bandwidth in the visible range of the electromagnetic spectrum and a state in which the filter transmits radiation in a bandwidth outside the visible range of the electromagnetic spectrum. An illuminator provides light to the plurality of Fabry-Perot filters. A control system receives image data and controls the display apparatus to project an image onto an associated display surface. The control system includes a modulator which provides wavelength modulation signals to the plurality of Fabry-Perot filters to modulate a color of pixels in the image and causes selected ones of the Fabry-Perot filters to shift into the bandwidth outside the visible range to modulate the brightness of pixels in the image.
