Abstract: A microimprint/nanoimprint device includes a mold, a substrate and an energy transferring module. The substrate is disposed oppositely to the mold and at least has a molding material layer. The energy transferring module includes an energy transferring member and at least one energy source, wherein the energy transferring member is connected to the substrate or the mold, and the energy source provides imprint energy to the substrate or the mold, such that at least part of the imprint energy goes through the energy transferring member to the substrate or the mold for performing imprint molding.

Abstract: Provided is a closed-loop feedback control positioning stage comprising at least one block formed therein, a plurality of hinge mechanisms for attaching the block in the stage, at least one actuator formed in the block, the actuator adapted to bend for moving the block in at least one direction, and a plurality of strain gauges each attached in a corresponding hinge mechanism for measuring its strain. The invention can repeatedly position the block at the moved location for carrying out a highly precise positioning of the stage.

Abstract: A vibration isolation device for isolating a vibration source from a carried member, includes: a carrier for carrying the carried member; a housing positioned on the vibration source, and formed with an accommodating space; a cover for sealing an open end of the housing; a base mounted in the accommodating space, and extended through the cover to be connected to the carrier; a plurality of connecting members mounted in the accommodating space and around the base, wherein each of the connecting members is connected to the base and the cover; and a plurality of actuators provided in the connecting members respectively, for changing vibration of the connecting members and the base when the vibration source vibrates, so as to minimize vibration of the carrier, thereby achieving the effect of isolating vertical and horizontal vibrations.

Abstract: The microstructure imprint device of the invention comprises: a supporting plate, a substrate, a moldable layer, a mold, and a microwave source, wherein the microwave discharged from the microwave source is being provided to the substrate, the moldable layer and the mold for heating up the moldable laye so as to soften the moldable layer, and the substrate having a layer of moldable layer arranged thereon is being placed on the supporting plate, and the mold is disposed at a position corresponding to the substrate and the supporting plate such that the mold can be pressed on the moldable layer for pattern transferring. The device the present invention is capable of enhancing the thermal state of a moldable layer in a short time by means of electromagnetic wave, such that the moldable layer can be heated in a short time and further the moldable layer can be softened.

Abstract: The invention, relating to an internal, active, compensatory and method and device for the rotational main-shaft of a cutting tool with axial bias-and-swing, mainly applies an active technique to a gas-floating main-shaft to thereby control its bias-and-swing. A sensor at the exterior of the main-shaft directly measures the axial bias-and-swing of the cutting tool. Taking the measured data as feedback signals, the cutting point of the cutting tool is maintained at an axial positioning accuracy that is predetermined. Further, the invention is arranged with an electromagnetic controlling module to the mandrel's tail end at the interior of the main-shaft for taking non-contacting magnetic force to finely tune the axial position of the mandrel, such that an active compensatory function of the axial position of the cutting point of a cutting tool in action is achieved.

Abstract: A load-adjustable SAW (Surface Acoustic Wave) actuator arrangement includes a platform having two sliding bearings symmetrically disposed at two sides; a SAW actuator disposed in the platform between the sliding bearings for producing a surface acoustic wave at the top surface thereof, a slider disposed inside the platform and movable by the SAW actuator along the sliding bearings, and a support structure. The slider has a pressure bearing structure disposed in contact with the top surface of the SAW actuator and two positioning portions respectively supported on the sliding bearings. The support structure applies a predetermined force to the slider subject to the load carried on the slider, keeping the contact pressure between the slider and the SAW actuator about a constant value.

Abstract: A roller gear cam index mechanism including a turret having pairs of adjacent rollers radially arranged on a circumference thereof. Each pair of rollers is engaged between adjacent ribs on a globoidal cam. The angle between the line up direction of every pair of rollers and the tangent direction of the turret circumference is a variable between 0 to 90 degrees. The rollers are modified globoidal rollers which are selected having difference maximum radii and vertex positions.
