Abstract: A shaft device includes a nut support including a shaft hole, a spline shaft extending through the shaft hole of the nut support, a spline nut having a tubular shape, a bearing of thrust type rotatably supporting the spline nut relative to the nut support, and a biasing member configured to bias the bearing in an axial direction of the spline shaft. The spline nut is disposed coaxially with a portion of the spline shaft protruding upward from the shaft hole and connected to the spline shaft through a spline mechanism.

Abstract: A processing method for a plate-shaped workpiece that has a transparent substrate, a first resin layer stacked on a front surface of the substrate, and a second resin layer stacked on a back surface of the substrate and in which the first resin layer is segmented into plural regions by plural planned dividing lines that intersect each other, includes sticking an expandable adhesive tape to the second resin layer, irradiating the workpiece with a laser beam with such a wavelength as to be absorbed by the first resin layer and transmitted through the transparent substrate, the laser beam removing the first resin layer along the planned dividing lines by ablation, the laser beam also forming a modified layer whose refractive index or mechanical strength is different from surroundings along the planned dividing lines.

Abstract: A fingerprint identification module packing method is provided. Firstly, plural fingerprint identification modules are attached on a supporting plate. Then, plural covering plates are attached on fingerprint sensing chips of the fingerprint identification modules. Then, the fingerprint identification modules are transferred to vacuum adsorption holes of a vacuum adsorption fixture. Then, the fingerprint sensing chips, the corresponding covering plates and corresponding metal terminals are welded by a laser welding process. Afterwards, the vacuum adsorption fixture is disabled. Consequently, the plural fingerprint identification modules are transferred to the packing plate.

Abstract: A tool has an hydraulic cylinder drive unit and an electric control unit, a stationary portion removably connected to a first busbar, a movable portion removably connected to a second busbar, and a loading portion for clamping connecting rods. The movable portion is movably connected to a first and second stationary shaft of the stationary portion, the movable portion is fixedly connected to the hydraulic cylinder drive unit by a movable shaft, the movable shaft is driven to slide axially with respect to the first and second stationary shaft by the hydraulic cylinder drive unit, the loading portion is movably connected to the second stationary shaft and slides between a body of the stationary portion and a body of the movable portion, the loading portion rotates around the second stationary shaft.
