摘要： A capacitive proximity sensor of the present invention principally comprises a sensor electrode, a sensor circuit, a detection circuit, and a microcomputer. The sensor circuit has an LC parallel circuit and an LC series resonant circuit. Furthermore, the single sensor electrode is connected in parallel with the LC parallel circuit. By decreasing the drive voltage applied to the sensor electrode, the radiated noise generated by the sensor electrode is also decreased. In addition, foot detection sensitivity can be improved by amplifying the detection signal with the LC series resonant circuit.

摘要： A motor comprises: a shaft; a permanent magnet rotor in which a permanent magnet and a gear member 32 are united; and a stator, arranged facing the permanent magnet. The gear member 32 has a pinion 33 and a mounting part 34. The mounting part 34 has: a circumferential-direction constraining part 34a, which constrains the circumferential movement of the permanent magnet; axial-direction constraining parts 34b, 34c, which abut both the top and bottom surfaces of the permanent magnet, so as to constrain the axial movement of the permanent magnet; and a plurality of elastic pieces 34d that apply a radially outward biasing force to the inner peripheral face of the permanent magnet.

摘要： The resonance frequency of an LCR resonance circuit is f1 and the determination voltage signal is V1, when an object is not in the proximity of a sensor electrode. The resonance frequency of the LCR resonance circuit is f2 and the determination voltage signal is V2, when a human body is in proximity of the sensor electrode 22. The resonance frequency of the LCR resonance circuit is f3 and the determination voltage signal is V3, when water is in the proximity of the sensor electrode. The LCR resonance circuit has the relationship f1>f2>f3. A control unit controls a high-frequency signal S0 so as to satisfy the relationship V2>V1>V3, and a human body or water being in the proximity of the sensor electrode is distinguished.

摘要： A brushless motor has a drive circuit component mounted on a stator which has plating conducted on a copper foil land to facilitate soldering. Need for a plating line from the outside is eliminated by providing an internal plating connection trace connected to a power feed terminal portion which is subsequently cut by a guide hole for an armature coil. An adhesive resin is applied to the stator where the circuit drive component is installed and the guide hole to adhere simultaneously to the stator to a bracket and the armature coil to the stator and bracket.

摘要： One end of a shaft is fixed to a first portion of a housing. An eccentric rotor is located in the housing rotatably on the shaft. The other end of the shaft is fitted into a concave portion on a second portion of the housing, so the rotor may be assembled in the housing in a simple manner and radial movement of the shaft can be prevented without enlarging the fixing portion of the shaft. Even if the diameter of the shaft is small, the shaft can withstand an impact resulting from dropping of the motor.
