    摘要： A fiber laser oscillator (1; 100) has an optical fiber (10), a pumping light emitting device (30), a light guide member (40; 140), and a core member (50). The core member (50) is configured to have a flat plate-shaped, cylindrical, annular, or hollow spherical configuration. The optical fiber (10) is wound around the surface of the core member (50) or partially embedded within the surface of the core member (50). The light guide member (40; 140) has a light receiving surface (40a) and an opposite surface (40b) opposing the receiving surface. The opposite surface (40b) of the light guide member (40; 140) contacts the circumferential surface of the core member (50). Light (Lin) emitted from the light emitting device (30) travels (i.e., pumping light (Lin)) travels within the core member (50) along the circumference of the core member (50) and excites the core portion (12) of the optical fiber (10).

    摘要： A cylindrical grinder includes a workpiece support section adapted to support a generally cylindrical workpiece and rotate the workpiece about a rotational axis, and a wheel head adapted to support and rotate a grinding wheel. The wheel head is moved relative to the workpiece support section, along a first direction parallel to a rotational axis of the workpiece and along a second direction perpendicular to the first direction in order to grind an outer surface of the workpiece. The wheel head is turnable relative to the workpiece so that a rotational axis of the grinding wheel can be tilted within a plane substantially passing through the rotational axis of the grinding wheel and the rotational axis of the workpiece, within a range extending across a reference plane perpendicular to the rotational axis of the workpiece. Further, link-type parallel link mechanisms for moving the grinding wheel are disclosed.

    摘要： A fiber laser oscillator 1 is provided with a pumping light source 30 for emitting pumping beams Lin; beam condensing means (light duct) 50 for condensing the pumping beams Lin emitted from the pumping light source 30; and a laser oscillation optical fiber 10 for receiving the pumping beams Lin condensed by the beam condensing means 50 to generate an output laser beam Lout. The beam condensing means 50 has an incident surface Min for making the pumping beams Lin from the pumping light source 30 incident thereon and an emission surface Mout for emitting the pumping beams Lin therefrom. The emission surface Mout is made smaller in area than the incident surface Min. Further, the area of the emission surface Mout is made to be the same as or smaller than that of one end surface of the laser oscillation optical fiber 10.

    摘要： In order to detect accurately a seating of clamped body and a clamping force at a seating, the workpiece supporting device has plural seating mechanisms 40. Each of the seating mechanisms 40 includes a load sensing element 45 receiving a clamping force or a fixing force. The load sensing element 45 consists of a material having a characteristic that said load sensing element is not substantially deformed by an applied load, especially it consists of a composite material dispersing a material having a pressure resistance effect or a magnetic resistance effect in a matrix of an electric insulation ceramics material. An abnormal clamping or fixing of the clamped body and an abnormal overload are detected by detecting an output from plural load sensing elements 45 supporting the clamped body.

    摘要： Optical waveguides, lens arrays and laser collecting devices are disclosed. The optical waveguide is formed with an output surface which is made smaller in dimension in a fast axis direction than an input surface. The waveguide collects in the fast axis direction plural laser beams output from plural laser emitting parts arranged in the fast axis direction and outputs from the output surface. The entrance surface of the optical waveguide is provided with first lenses to correspond respectively to the plural laser emitting parts. Each of the first lenses is located to be offset first predetermined distances from a corresponding one of the laser emitting parts in the beam traveling direction and in said fast axis direction, and the first predetermined distances are determined for each of the first lens in taking into account the focal length of each first lens and an angle which each first lens makes with the output surface of the waveguide.
