摘要： A manpower-assisting power apparatus for appropriately applying power to assist human power without using a large, high cost torque detection apparatus, and enabling operation by human power to be continued even when external motor-generated power is no longer applied. This manpower-assisting power apparatus is equipped with a differential gear mechanism preferably comprising a pedal drive bevel gear, a motor drive bevel gear, and a pair of corresponding small bevel gears driving a rotary output member. The rotational speeds of the motor drive spur gear integrated with motor drive bevel gear, and pedal drive sprocket integrated with pedal drive bevel gear are respectively detected by a motor speed sensor and at least one manpower rotational speed sensors operating in a noncontact fashion. These detected rotational speeds are used by a controller to preferably drive the motor to maintain a constant ratio between these rotational speeds. Also, this power apparatus may employ a planetary gear system to minimize mechanical loss when transferring power from the motor-manpower combination to the output member driving a wheel.

摘要： A brushless DC motor, whose stator (10) is a combination of stator yokes (11, 16), a bobbin (14) on which a magnetic field coil (15) is wound and to which terminal pins are provided, and a base plate (20). The stator (10) is fixed to the base plate (20) by a protrusion (12c) provided on the bobbin (14) or by a flange (18a) formed on a bearing. The widths of magnetic poles (11a, 16a) of the stator, which are measured in the circumferential direction of the stator, are smaller than the width of one of the poles of a rotor magnet (5). Thereby, the position of a stable point is a maximum excitation torque position. Further, a magnetic pole sensing element (21) is provided at a place which is shifted in the circumferential direction from the middle position of one of the magnetic poles of the rotor magnet (5).

摘要： A light source apparatus with modulation function has a wavelength conversion module (75) composed of a nonlinear optical material with a structure having a nonlinear constant modulated periodically. It outputs a difference frequency or sum frequency produced by multiplexing pumping light from semiconductor laser light sources (71) and (72) with different wavelengths through a WDM coupler (74) and by launching the multiplexed light into the optical waveguide. The semiconductor laser light source (72) includes a diffraction grating. The semiconductor laser light source (71) includes a section for modulating output light emitted from its semiconductor laser, and is connected to an external FBG (73) which has a reflection band narrower than a resonance wavelength spacing determined by the device length of the semiconductor laser.
