    Abstract: PROBLEM TO BE SOLVED: To provide an inexpensive apparatus for correcting positional shift of a beam spot in a low speed scanning direction by vertically adjusting the position of laser beam, in a raster output scanning system. SOLUTION: A raster output scanning system 10 consists of a photosensitive image forming unit 30, a modulation type laser beam generating unit 13 for generating a beam spot toward the photosensitive image forming unit 30, a horizontal scanning unit 29 for horizontally sweeping the beam spot generated in the modulation type laser beam generating unit 13 so as to traverse the photosensitive image forming unit 30, and a vertical scanning unit 12 having the rotary mirror 15 adjacent to the modulation type laser beam generating unit 13 to perform the positioning in the vertical direction of the beam spot in the vertical developing direction of the photosensitive image forming unit 30.

    Abstract: PROBLEM TO BE SOLVED: To provide the mass measuring system, which automatically detects the property of a paper sheet and automatically adjusts the setting of a paper- sheet conveying mechanism. SOLUTION: This system 140 includes an actuator 141, a paper-sheet-position sensor 142 and a touch-sense sensor system 200. The actuator 142 applies known force on a paper sheet 150, moves the paper sheet 150 and passes the paper sheet to the paper-sheet-position sensor 142. The paper-sheet-position sensor 142 measures the speed of the paper sheet 150 at each point. The paper sheet 150 passes the touch-sense sensor system 200. Thus, the friction coefficient of the paper sheet is measured. A controller can measure the mass of the paper sheet 150 by using these measured values. This is utilized, and the performance of the paper-sheet carrying path in a copying machine or the like is changed.

    Abstract: PROBLEM TO BE SOLVED: To provide a micro-machined element thermally isolated from a substrate. SOLUTION: The silicon structure is at least partially thermally isolated from the substrate by a gap formed in an insulation layer disposed between the substrate and a silicon layer in which the silicon structure is formed. In embodiments, the substrate is made of silicon and the silicon layer is made of single crystal silicon. In embodiments, the gap is formed such that a surface of the substrate under the gap is maintained substantially unetched. In other embodiments, the gap is formed without affecting the surface of the of the substrate underlying the gap. In particular, the gap may be formed by removing one portion of the insulation layer by etching not affecting the surface of the substrate underlying the gap. In embodiments, the etching is highly selective between the material of the insulation layer and the material of the substrate. Selectivity of the etching may be 20:1 or greater.

    Abstract: PROBLEM TO BE SOLVED: To reduce deflection caused by etching. SOLUTION: Structure for a micro-device is fabricated by forming a first layer of sacrifical material, a layer of a structural material over the first sacrifical material layer, a second layer of sacrifical material over the structural material layer, and a protective layer over the second sacrifical material layer. A release etch is used to remove the first and second sacrifical material layers at substantially same rate. A structural feature is fabricated by forming a first layer of a first material, a layer of structural material over the first layer of the first material, at least one cut in the structural material layer, and a first layer of a sacrifical material different from the first material over the structural material layer such that an interface is created between the first layer of the sacrifical material and the first layer of the first material in at least one cut.

    Abstract: PROBLEM TO BE SOLVED: To provide a mechanism aligning chips and an optical fiber with a simple method by using a mirror without aligning them under the use of a microscope. SOLUTION: When an MEMS-based adjustable mirror module is used, it is possible to make an optical fiber existing in a substrate to be in an alignment state more quickly, at a lower cost and more simply. Moreover, when the movable mirrors formed on the substrate are used, it is possible to prevent alignment failure by adjusting an optical path after the optical fiber is attached to the substrate and, thereafter, by fixing the mirrors at that positions.
