  • Patent number: 8170768
    Abstract: The present invention provides a slip rate estimating device measuring a slip ratio without the need for a body speed and a slip ratio control device using the slip ratio estimating device. A motor torque measured by a torque measuring instrument is input to each of a vehicle model (601) and an SRE (602) that performs calculations including time differentiation of the slip ratio. The vehicle model (601) derives a wheel rotation speed, a wheel rotation acceleration, and a body speed. The vehicle model (601) outputs the wheel rotation speed and the wheel rotation acceleration to the SRE (602). The SRE (602) outputs the slip ratio based on the motor torque, the wheel rotation speed, and the wheel rotation acceleration.

  • Publication number: 20090275836
    Abstract: Disclosed is an ultrasonic probe having an organism contact portion that is shaped for use along a comparatively large curvature and can easily be used while closely contacting an organism, and that has an adequately reduced size. According to the technique of the invention, a first cylinder pulley 5, secured to a probe casing 7, an arm 16, secured to a motor spindle 17 that is extended through a first pulley, and a second cylinder pulley 8, rotatably arranged on the opposite side, are coupled together by a wire 6. The second pulley is equipped with a slider shaft 14 that is arranged, in an extensible manner, by a slider bearing 15. The slider shaft is quipped with a roller 10 that contacts a guide rail 12 of the probe casing, and an ultrasonic element 2 is attached to the distal end of the slider shaft to provide the telescopic structure for the slider shaft. In this manner, the size of a scanning mechanism, for oscillating the ultrasonic element along a large curvature, is reduced.

  • Publication number: 20060241424
    Abstract: An excellent ultrasonic diagnostic apparatus is provided that can form a three-dimensional image in a more spatially-correct position regardless of an ultrasonic probe to be used, without leading to deterioration of the productivity of the treatment. An ultrasonic probe includes an ultrasonic transducer, a rotation transmission mechanism, a rotary encoder, a transducer-swinging motor and an encoder correction ROM. In the encoder correction ROM, an actual swing scanning angle of the ultrasonic transducer with respect to each count value that is obtained by counting pulses from the rotary encoder is stored in advance. A three-dimensional image processing means forms a three-dimensional image of a principal cross-section scanning plane in a direction at the actual swing scanning angle, while correcting an encoder count value from an encoder counter according to contents of the encoder correction ROM that are read out by a main controlling means.

  • Publication number: 20060085151
    Abstract: A technique for smoothly speed-controlling a speed of a motor whose time constant is relatively small, such as a supersonic motor, under a relatively rough speed control profile and a simple configuration is disclosed. According to this technique, a frequency division number calculating section 1 changes a division number A under the relatively rough speed control profile and sets for a frequency division number setting register 2. The comparator 3 outputs a+count signal if the division number A set by the frequency division number calculating section is greater than a current division number B counted by a frequency division number counter 4 (the division number A> the division number B), and outputs a—count signal if the division number A< the division number B.
