    摘要： A combined-laser-light source includes: a plurality of semiconductor lasers; an optical fiber; and an optical system which converges a bundle of laser beams emitted from the plurality of semiconductor lasers, and makes the converged bundle of the laser beams enter the core of the optical fiber so that the laser beams are combined in the optical fiber when the laser beams pass through the optical fiber. The optical system is aligned with the optical fiber so that the converged bundle of the laser beams is incident on an area of an end face of the core when steady temperature control is performed on the combined-laser-light source, where the area is concentric with the end face of the core, and has a diameter equal to or smaller than half of the diameter of the core.

    摘要： The present invention is directed to a drum washing machine. In particular, the drum washing machine includes a rotating tub, wherein the rotating tub has a cylindrical drum having a front formed with a circular opening through which laundry is put into the rotating tub and having a rear that is closed. The drum washing machine further includes a DC brushless motor for generating a driving force for wash, rinse and dehydration operations and a rotor. The drum washing machine further includes a rotational shaft of the motor having a front end directly fixed to the rotating tub and a rear end fixed to a core of the rotor, so that torque developed by the motor is directly transmitted to the rotating tub. A current detector is provided in the drum washing machine for detecting electric current flowing into the motor. A torque control unit is also provided in the drum washing machine for performing a vector control for the motor on the basis of the current detected by the current detector, so that torque developed by the motor is rendered optimum for at least the wash and dehydration operations. A speed control unit for controlling a rotational speed of the motor, based on the current detected by the current detector and a laundry amount determining unit for determining an amount of laundry in the rotating tub, based on a magnitude of an accumulated value of torque current in a period when a rotational speed of the motor is accelerated are also provided in the drum washing machine of the present invention.
