20100309753 | FISH FINDER - This disclosure provides a fish finder, which includes a transmission module and a reception module, for outputting an ultrasonic wave underwater, receiving an echo, and outputting a reception signal corresponding to an intensity of the received echo, a control module for generating echo data corresponding to a depth based on the reception signal, a display module for displaying the echo data, and a user interface for receiving a user's operation. The control module causes the display module to display the echo data so that the echo data is displayed in two or more display screens. At least one display screen displays an area having a color different from a background color. A part of the echo data at a depth range corresponding to a height of the area is displayed in the other display screen so as to expand the echo data in a depth direction. The user interface specifies a position and a size of the area via the user's operation. | 12-09-2010 |

20080238265 | Stepping motor and rotor - A stepping motor has a stator and a rotor disposed to surround the stator. The rotor has an annular magnet which has a plurality of magnetic poles formed along a circumference thereof, and a comb-teeth-shaped back yoke which is disposed to surround the magnet and has a plurality of comb teeth, the comb teeth being faced boundary positions of adjacent magnetic poles. | 10-02-2008 |
20080278012 | VIBRATION-GENERATING STEPPING MOTOR - The present invention provides a vibration-generating stepping motor including: two stator yokes; a bearing that magnetically couples the two stator yokes; a rotor frame that rotates on a circumference of the stator yokes; and an eccentric weight that shifts a gravity center of the rotor frame from a rotation center of the rotor frame. | 11-13-2008 |
20080278024 | RADIAL STEPPING MOTOR - The present invention provides a radial stepping motor including: a coil that is comprised of a self-bonding magnet wire wound and fusion-bonded and that has annular surfaces; stator yokes that are supported by the annular surfaces of the coil; and bonding sheets bonding the stator yokes to the coil. | 11-13-2008 |
20090218903 | Stepping motor - A single phase stepping motor has a stator, and a rotor disposed to surround the stator. The stator includes first and second annular stator yokes, which are disposed opposite to each other and have a plurality of pole teeth formed along a circumference thereof, and an annular stator coil disposed between the first and second stator yokes. The rotor includes a ring magnet, which is disposed to surround the first and second stator yokes, and has a plurality of magnetic poles formed along a circumference of the rotor, and a shaft disposed at a center position of the magnet. At least a partial region of a gap formed between each of the pole teeth and the opposing magnetic pole of the magnet is non-uniform in a predetermined direction. | 09-03-2009 |
20090251017 | Vibration motor - A vibration motor includes a rotary shaft, an armature core secured to the rotary shaft and having a plurality of salient poles, an armature coil wound around each of the salient poles except at least one salient pole, a frame serving as an outside cover, a plurality of magnets secured to the frame and having respective different polarities, and a weight adapted to rotate together with the rotary shaft and disposed eccentrically, wherein the weight is disposed inside the frame and secured to the armature core in such a manner that at least a part of the weight is inserted in a hollow provided in at least the one salient pole having no armature coil. | 10-08-2009 |

20140064025 | TARGET OBJECT DETECTION DEVICE AND METHOD OF DISPLAYING ECHO DATA IN THE TARGET OBJECT DETECTION DEVICE - A target object detection device is provided. The device includes a signal processor, a display unit, and a controller. The signal processor receives a reception signal generated based on an echo of an ultrasonic wave from a target object and generates echo data corresponding to a distance from a transmission source of the ultrasonic wave to the target object every time the ultrasonic wave is transmitted. The display unit has a display screen with a first side and a second side that is turnable in an axial direction perpendicular to the display screen, and displays an image on the display screen based on the echo data. The controller sets a range with respect to time at which the ultrasonic wave is transmitted, and outputs the echo data corresponding to the ultrasonic wave within the time range according to turning of the display screen. | 03-06-2014 |
