    Abstract: A method for fabricating an integrated, micromachined structure, such as a torsional scanner, that includes a reference member, such as a frame, a pair of torsion hinges, and a dynamic member that is coupled to the reference member by the torsion hinges. The method includes providing a wafer that has been formed from silicon material, and that has both a frontside and a backside. A membrane is formed in the wafer by etching a cavity in the silicon material from the backside of the wafer. The method also includes establishing a pattern that defines the mirror surface and the torsion hinges on the frontside of the wafer at the membrane formed therein. The frontside of the wafer is processed to form therein the dynamic member and the torsion hinges that support the dynamic member for rotation about the axis.

    Abstract: A compact medium scanner (100) scans a surface (132) of a medium (134) with a beam of light (106). A medium transport mechanism (202, 206) advances the surface along a medium transport path through a scanning station. A light source (104) produces a collimated beam of light (106) that impinges upon a mirror plate (112) of a micromachined torsional scanner (108). A pair of coaxially aligned torsion bars (304) support the mirror plate (112) within the torsional scanner (108). A mirror-surface drive means (306, 312) rotates the mirror plate (112) about the torsion bars (304). A single reciprocation of the mirror plate (112) by the drive means (306, 312) deflects the beam of light (106) over a fan-shaped region having a virtually fixed vertex (128) on the mirror plate (112). Scanner optics (116, 122) direct the fan-shaped region beam of light (106) onto the surface (132) of the medium (134) then present in the scanning station to thereby scan across the medium (134) with the beam of light (106).

    Abstract: An X-ray lithography apparatus permits the successive exposure of each of four quadrants of a semiconductor wafer through a single mask. The mask overlays one quadrant of the wafer at a time and the wafer is rotated through 90 degrees after exposure of a quadrant to allow exposure of succeeding wafer quadrants; each wafer quadrant is independently aligned to the mask prior to exposure. In an alternative preferred embodiment, a rotatable diaphragm is used to select a single mask quadrant from a mask which overlays the entire surface of the semiconductor wafer. Both the wafer and the diaphragm may be rotated to allow various exposure combinations of mask and wafer quadrants.

    Abstract: A method of making an electron permeable window is provided which entails depositing a thin film of an inert, high strength material or compound having a low atomic number onto a substrate by chemical vapor deposition (CVD). Following that deposition, a window pattern and window support perimeter are photolithographically defined and the substrate is etched to leave the desired window structure. For a particular class of materials including SiC, BN, B.sub.4 C, Si.sub.3 N.sub.4, and Al.sub.4 C.sub.3, films are provided which are exceedingly tough and pinhole free, and which exhibit nearly zero internal stress. Furthermore, due to their extreme strength, these materials allow fabrication of extremely thin windows. In addition, because of their low atomic number and density, they have excellent electron penetration characteristics at low beam voltages (15 to 30kV), so that most conventional CRT deflection schemes can be used to direct the beam. Also, such films are remarkably resilient and chemically inert even when very thin and can easily withstand large pressure differences.

    Abstract: A method and apparatus for selectively transferring magnetic toner from a reservoir to the imaged areas of a copy web. The reservoir is used to develop a donor web in which a multiplicity of microfields have been recorded. The donor web is subsequently passed into non-contacting proximity to a copy web having a latent magnetic image thereon. The toner is selectively attracted to the stronger magnetic forces in the imaged areas of the copy web and remains on the donor web in the non-imaged areas. Another aspect of the invention provides for the neutralization of the donor web microfields prior to the toner transfer to enhance the development process.

    Abstract: A fenestration piercing the otic capsule bone of the cochlea receives a therapeutic appliance, such as a microactuator, plug, micropump for drug or therapeutic agent delivery, electrode, and the like. Several different ways of achieving a ‘water tight’ seal between the otic capsule bone and the therapeutic appliance are provided. The therapeutic appliance may be implanted with or without a sheath or sleeve lining the wall of the fenestration formed using specialized surgical burrs. The burrs permit safely fenestrating the otic capsule bone adjacent to the scala tympani of the cochlea without damaging the basilar membrane or organ of corti. This approach may also be adopted for safely fenestrating other areas of the inner ear such as the scala vestibuli, bony labyrinth of semicircular canals, or walls of the vestibule, or the oval or round windows thereof.

    Abstract: A fiber optic switch (400) includes a fiber optic switching module (100) that receives and fixes ends (104) of optical fibers (106). The module (100) includes numerous reflective light beam deflectors (172) which may be selected as pairs for coupling a beam of light (108) between a pair of optical fibers (106). The module (100) also produces orientation signals from each deflector (172) which indicate its orientation. A portcard (406) included in the switch (400) supplies drive signals to the module (100) for orienting at least one deflector (172). The portcard (406) also receives the orientation signals produced by that deflector (172) together with coordinates that specify an orientation for the deflector (172). The portcard (406) compares the received coordinates with the orientation signals received from the deflector (172) and adjusts the drive signals supplied to the module (100) to reduce any difference between the received coordinates and the orientation signals. The switch (400) also employs optical alignment to precisely orient pairs deflectors (172) coupling a beam of light (108) between optical fibers (106).
