  • Publication number: 20200386298
    Abstract: A motor includes a motor unit, a speed reduction mechanism, a motion conversion mechanism, and a housing. The motion conversion mechanism converts rotary motion of the speed reduction. mechanism into reciprocating rotary motion and transmits the motion to an output shaft. The speed reduction mechanism includes a worm, a first gear, and a second gear. The worm is disposed on a rotation shaft of the motor unit. The first gear transmits rotation of the worm and rotates about a first shaft. The second gear receives rotation of the first gear and rotates about a second shaft. The motion conversion mechanism includes a rotary member and a rod. The rotary member includes a sector gear and rotates about an axis of the first shaft. The rod couples the second gear and the rotary member. The output shaft includes an output gear that engages the sector gear.

  • Publication number: 20200342757
    Abstract: The disclosed image processing apparatus (10) includes a communication interface (12) and a processor (13). The processor (13) detects an image of an object from a surrounding image capturing the surroundings of a moveable body (1) and determines an action of the moveable body (1) based on the state of the detected object. The communication interface (12) outputs, to the moveable body (1), an instruction to perform the determined action. The processor (14) determines a first action of the moveable body (1) based on the state of the object detected from the surrounding image and outputs an instruction to perform the determined first action to the moveable body (1) via the communication interface (12). The processor (14) determines a second action of the moveable body (1) based on the state of the object detected from the surrounding image after the first action by the moveable body (1).

    Abstract: Provided is a disease diagnosis support method employing endoscopic images of a digestive organ using a neural network, and the like. The disease diagnosis support method employing endoscopic images of a digestive organ using a neural network trains the neural network by using first endoscopic images of the digestive organ, and corresponding to the first endoscopic images, at least one of definitive diagnosis result of being positive or negative for the disease of the digestive organ, a past disease, a severity level, and information corresponding to an imaged region. The trained neural network outputs, based on second endoscopic images of the digestive organ, at least one of a probability of being positive and/or negative for the disease of the digestive organ, a probability of a past disease, a severity level of the disease, and the information corresponding to the imaged region.

  • Publication number: 20200196389
    Abstract: A carrier containing a plurality of semiconductor wafers in a lot is transported into a heat treatment apparatus. Thereafter, a recipe specifying treatment procedures and treatment conditions is set for each of the semiconductor wafers. Next, a reflectance of each of the semiconductor wafers stored in the carrier is measured. Based on the set recipe and the measured reflectance of each semiconductor wafer, a predicted attainable temperature of each semiconductor wafer at the time of flash heating treatment is calculated, and the calculated predicted attainable temperature is displayed. This allows the setting of the treatment conditions with reference to the displayed predicted attainable temperature, to thereby easily achieve the setting of the heat treatment conditions.

    Abstract: A stator has four or more magnetic poles. A commutator has a plurality of segments arranged in the circumferential direction and a short-circuit conductor for short-circuiting predetermined segments from among these segments. Each segment has an angular width WS, and there is a gap of an angular width WU between the segments. A substantial angular width WB of each of an anode brush and a cathode brush satisfies (n?1)(WS+WU)+WU<WB<n(WS+WU)+WU, where n is an integer no less than two. A plurality of coils are each connected to the corresponding one of the segments in order to form n closed loops. The closed loops each pass through the corresponding segments and are electrically independent of each other.

  • Publication number: 20100264772
    Abstract: A direct current motor is provided that includes an armature core, a commutator, coils, positive brushes, and negative brushes. The armature core includes a stator. The stator has magnets the number of which is represented by P (where P is an even number greater than or equal to six). The coils are wound about the teeth by duplex wave winding. Alternatively, the coils are wound about the teeth such that each pair of coils that are spaced apart by 180° are connected common ones of the segments. Each of the positive brushes and the negative brushes has an angular width WB, at which it slides on the segments. When the angular width of the arrangement pitch of the segments is represented by WP (WP=360°/the number of the segments), and the angular width of the clearance between each pair of circumferentially adjacent segments is represented by WU, the angular width WB is set to satisfy the expression: WB?(4/P)×WP+WU.
