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 control unit 20, including a circuit board and a switch unit, is arranged in a housing space in a door handle. The switch unit has a switch component, which is fastened to the circuit board, a hard switch case, which covers the switch component, a soft pushbutton, which operates the switch component, and a hard cover member, which is fastened to the switch case. The pushbutton has a pushing part in the shape of a cap, a flange, which extends from the bottom end of the pushing part, and an operation projection, which is inserted into an insertion opening in a roof. The switch case and the pushbutton are united by the cover member, and the flange is brought into close contact with the roof all the way therearound, by the cover member.

摘要： The bottom end of a rotary shaft contacts a cover part of a cover member, while the top end of the rotary shaft protrudes upwards from a retaining plate. A planar first washer member, which is made from a hard material, is fastened to the rotary shaft, between a bottom plate of a rotor case and an oil-impregnated bearing. The first washer member is disposed without contact with the bottom plate of the rotor case and the oil-impregnated bearing.

摘要： A motion sensor comprises: a plurality of first light emitting elements, which emit lights having mutually different characteristics in the region of movement of the object to be detected; a light receiving element, which receives reflected light that is emitted from the first light emitting elements and reflected by the object to be detected; a second light emitting element, which emits light towards the light receiving element; and a separation member. A light guiding part, which guides light emitted from the second light emitting element so as directly irradiate the light receiving element, without passing through the region of movement of the object to be detected, and light blocking parts, which block light so that light from the first light emitting elements does not directly irradiate the light receiving element, are formed integrally with the separation member.

摘要： A sensor electrode has an upper side portion arranged on an automobile, a lower side portion arranged with a predetermined spacing from the upper side portion, and a connecting portion that connects the upper side portion and the lower side portion. A control unit inputs a signal for detecting a user to the upper side portion, the lower side portion, and the connecting portion, which are electrically connected. The lower side portion is arranged farther from an area through which the user passes than the upper side portion. The installation height of the upper side portion is greater than or equal to the installation height of the lower side portion.

摘要： Copper covered steel is used for metal terminals 50a, 50b in an antenna coil. Through holes penetrating in the Z direction and position restraining grooves that are formed continuous with these through holes are formed in a holder for holding the metal terminals 50a, 50b. Proceeding from the situation in which the metal terminals 50a, 50b have been driven into, so as to be press-fit in, the through holes in the holder, by bending the first ends in the Y direction and the second ends in the X direction, the first ends and the second ends are respectively fitted into position restraining grooves such that the positions of binding parts 50a1, 50b1 and lead wire connection parts 50a2, 50b2 are restrained.

摘要： In a brushless motor having a rotor in which a drive magnet 43 and a position detection magnet 44 are fixed to the inside of a rotor case 44, along the axial direction, an annular separation plate 45 having positioning parts 45a and 45b for positioning these in the circumferential direction is disposed between the drive magnet 43 and the position detection magnet 44. Thereby, the magnetic influence of the drive magnet can be limited, and thus a highly reliable position detection signal can be obtained.
