An optical system head of the laser processing machine includes a focusing optical system configured to deflect and condense an incident laser beam so that a target object to be processed is irradiated and a deflecting direction adjusting unit configured to adjust the direction of deflection of the laser beams about at least two axes perpendicular or substantially perpendicular to each other. A nozzle holding head of the laser processing machine includes a cutting nozzle configured to blow a cutting gas at a site of the target object, at which the laser beam is irradiated, and a nozzle position adjusting unit configured to adjust the position of the cutting nozzle in a top plane parallel or substantially parallel to the target object. The optical system head and the nozzle holding head are separately supported by an optical system nozzle support member configured to selectively advance or retract in three axis directions relative to the target object.

Laser processing machine

An autonomous moving apparatus includes a vehicle provided with a drive unit; a cover that is attached to the vehicle such that the cover either entirely or partially covers side, upper, and lower surfaces of the vehicle, and the cover is arranged to be displaced with respect to the vehicle; a detection unit arranged to output detection signals in accordance with relative displacement generated between at least one of the upper and lower surfaces of the vehicle and the cover facing at least one of the upper and lower surfaces; and a control unit arranged to control the drive unit in accordance with the detection signals output from the detection unit.

Autonomous moving apparatus

The present invention provides a linear motor device that can reduce a variation in thrust caused by a variation in attractive force. The linear motor device includes a linear motorand a control sectionthat controls the linear motor. The linear motorincludes a magnet membercomposed of permanent magnets having respective N poles and S poles alternately arranged in an axial direction, and a coil memberwhich is located orthogonally to the axial direction with respect to the magnet memberand through which the magnet memberis movable in the axial direction relative to the coil member. The control sectioncontrols current conducted through the coil memberso that a moving one of the magnet memberand the coil memberreciprocates within a use range L corresponding to a part of a pitch p between the magnetic poles N and S in the magnet member

Linear motor device and machine tool having the same mounted thereon

The present invention provides a linear motorthat can prevent a magnet memberfrom falling down when a power supply is turned off. A linear motorincludes a magnet membercomposed of permanent magnets having alternately arranged respective N poles and S poles and a coil memberwhich surrounds a periphery of the magnet memberand trough which the magnet memberis movable in an axial direction relative to the coil member. A magnetic substanceis provided in the vicinity of one end of the coil memberto allow the magnet memberto exert a magnetic attractive force.

Linear motor and machine tool having the same mounted thereon

The present invention provides a linear motorwhich uses a plurality of cylindrical linear motorsto increase power and which can guide forward and backward movements using a simple configuration, the linear motorrequiring reduced manufacturing costs. A plurality of cylindrical linear motorsare provided each of which has a shaft membermade of a permanent magnet and a coil unit. A motor supportis provided which is able to support the coil units of the plurality of cylindrical linear motorsarranged in parallel. The shaft members of the plurality of cylindrical linear motorsare coupled together at ends thereof by coupling members. A guide mechanismis located inside the arrangement of the cylindrical linear motorsto guide movement of the shaft membersof the cylindrical linear motors. The number of guide mechanismsis smaller than that of the cylindrical linear motors. For example, the single guide mechanismis provided.
