  • Patent number: 10525579
    Abstract: In order to provide an electric tool with good operability that can extend the life of and suppress breakage of a switching element for controlling energization of a brushless motor, a control unit (50), after an operation switch (5) is turned off, does not immediately turn off an inverter circuit (43) (does not set the duty of a PWM signal to 0), and instead normally operates the inverter circuit (43) with a low-duty PWM signal and waits until a rotation speed of a brushless motor (6) reaches a predetermined rotation speed or less to turn off the inverter circuit (43) (to set the duty of the PWM signal to 0).

  • Publication number: 20190041501
    Abstract: An optical scan type object detecting apparatus, includes a mirror unit including a first mirror surface and a second mirror surface facing each other; a light source; and a light receiving element. A light flux is projected so as to scan by rotation of the mirror unit via the first mirror surface and the second mirror surface, and some of the light flux scattered by an object is received by the light receiving element. An area of the light flux received by the light receiving element becomes larger than an area of the light flux projected from the mirror unit. An incident angle ?inc of the light flux emitted from the light source relative to the first mirror surface satisfies a formula: ?/2?7<?inc<?/2+11, where ? is an intersecting angle between the first mirror surface and the second mirror surface.

  • Publication number: 20180372491
    Abstract: An optical scan type object detecting apparatus, includes a light source that emits a light flux with a cross section being circular, a light projecting optical system into which a light flux emitted from the light source enters, a scanning device that makes a light flux scan in a main scanning direction, and a light receiving optical system that receives by a light receiving element a part of a light flux that is made so as to scan by the scanning device and is scattered on an object. The light projecting optical system shapes a light flux emitted from the light source such that a diameter, of a light flux made so as to scan by the scanning device, in a sub-scanning direction orthogonal to the main scanning direction becomes longer than a diameter in the main scanning direction, and, makes the shaped light flux enter the scanning device.

  • Patent number: 8040783
    Abstract: An optical information recording and reproducing apparatus relating to the invention employs a two-beam interference method. In the optical information recording and reproducing apparatus, a moving device moves an information recording medium between a recording and reproducing position and a retracting position, and a mirror moves together with the information recording medium. When the information recording medium moves to the recording and reproducing position, the mirror moves to a position which is displaced from the at least one of the reference beam and the information beam. When the information recording medium moves to the retracting position, the mirror moves to a position where the mirror can reflect the at least one of the reference beam and the information beam toward a detector for detecting a deviation of the at least one of the reference beam and the information beam.

  • Patent number: 7549497
    Abstract: A vehicle includes a wheel speed sensor sensing a vehicle speed V, a 2WD/4WD switch operative to input an instruction to switch between a two-wheel driving state and a four-wheel driving state, a transfer and an actuator switching the two-wheel driving state and the four-wheel driving state, and an ECU driving the actuator. The ECU instructs the actuator to switch from the four-wheel driving state to the two-wheel driving state regardless of the switching instruction from the 2WD/4WD switch if the vehicle tows a trailer and runs in the four-wheel driving state when the vehicle speed exceeds a predetermined value. Consequently, it is possible to provide a four-wheel drive vehicle capable of running while towing an object and also avoiding an increase in the size of the peripheral parts of driving wheels.
