  • Patent number: 8974392
    Abstract: An ultrasonic probe has an organism contact portion that is shaped for use along a comparatively large curvature and can easily be used while closely contacting an organism. The probe includes a first cylinder pulley secured to a probe casing, an arm secured to a motor spindle extending through the first pulley, and a second cylinder pulley rotatably arranged on the opposite side and coupled to the first pulley by a wire. The second pulley is equipped with a slider shaft that is arranged to be extendable by a slider bearing. The slider shaft is equipped with a roller contacting a guide rail of the casing. An ultrasonic element 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.

  • Patent number: 8953312
    Abstract: In a casing, a printed circuit board is arranged such that a first side of the printed circuit board has a first angle of ?° with respect to a first side surface plate. A cooling device is arranged to have a second angle of ? with respect to the first side surface plate. Accordingly, an amount of cooling air flowing in and out via an air intake port and an air discharge port may be increased. Furthermore, by reducing the angle of the change in the flow direction of the cooling air flowing over the printed circuit board, the cooling air flowing over the printed circuit board may be made to efficiently flow through an air discharge port 119a. Furthermore, the efficiency with which a heat-generating component on the printed circuit board is cooled may be improved.

  • Patent number: 8797750
    Abstract: A first metal sheet and a second metal sheet are arranged opposite a printed circuit board including a second connector that fits into a first connector that is arranged at one end of a cable. A hole section through which the first connector passes is arranged in each of the first metal sheet and the second metal sheet. The first connector fits into the second connector by passing through each of the hole sections of the first metal sheet and the second metal sheet. The first metal sheet and the second metal sheet support a connector case of the first connector, thus improving the load bearing characteristics of the cable connection.

  • Patent number: 8708915
    Abstract: The invention provides an ultrasonic probe having a frame to constitute a part of a cubicle, a motor fixed on the frame, a first arm with one end fixed on a rotating shaft of the motor, and a second arm with one end rotatably coupled with the other end of the first arm via a coupling shaft and with the other end having an ultrasonic element mounted thereon. The second arm has a lengthwise long groove and is slidably engaged with the fixed shaft of the frame in the direction of length. The length from an end of the second arm where the ultrasonic element is mounted on the coupling shaft is designed to be longer than the length from the rotating shaft to the coupling shaft, and further, to be longer than the length from the rotating shaft to the fixed shaft.
