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.

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.

The vision recovery training device of the present invention includes a target 2 to be watched; a driving device 3 that moves the target 2 and a visual field plate 13 having three peep windows 5a to 5c through which the target 2 is peeped; and is characterized in that the three peep windows are respectively horizontally arranged in parallel, the peep window 5b provided at a center is located on an extended line of a moving direction of the target 2, other two peep windows 5a and 5c are located at positions spaced by an equal distance from the peep window 5b located at the center and a distance between the other two peep windows 5a and 5c are substantially equal to an interval of pupils of a person.

Abstract: The ultrasonic probe of the present invention includes an ultrasonic element unit for transmitting and receiving ultrasonic waves, an oscillation mechanism for causing oscillation to the ultrasonic element unit and a detector for detecting the oscillation of the ultrasonic element unit. The detector detects the oscillation angle and the oscillation origin of the ultrasonic element unit, and when the oscillation range of the ultrasonic element unit is divided at its oscillation origin into two regions of a positive region and a negative region, the detector detects in which area the ultrasonic element unit is located. In use of the ultrasonic probe, a control of origin return for returning the ultrasonic element unit to its oscillation origin is performed on the basis of the result of the detection by the detector.

Abstract: An ultrasonic probe is provided which may be employed in medical applications to radiate an ultrasonic wave for inspecting the interior of a patient's body noninvasively. The ultrasonic probe includes a scan mechanism which consists of a rotating mechanism and a swinging mechanism. The rotating mechanism is designed to rotate a cylindrical holder having installed thereon a piezoelectric element which emits an ultrasonic wave and receives the echo. The swinging mechanism is designed to swing a rotary base which supports the rotating mechanism to swing the cylindrical holder about an axis of rotation extending perpendicular to that of the piezoelectric element.

Abstract: A loader conveys a holder, carrying thereon a disc cartridge, between a cartridge ejection position and a reproducing/recording position. The loader has an engaging part which engages with a mechanical lock mechanism so as to release a holder pin in the mechanical lock mechanism from its locked condition in order to hold a movable chassis in a floating condition with respect to a stationary chassis and to lock the holding pin in the mechanical lock mechanism so as to fix the movable chassis to the stationary chassis when the holder has been moved to the cartridge ejecting side.

When the holder is moved to the reproducing/recording position, the holding pin provided on the holder engages with a shutter closing spring so as to retract an engaging part at the front end of the shutter closing spring through an opening in the holder in order to prevent the disc cartridge from making contact with the shutter closing spring, thereby making it possible to give a satisfactory feeling of insertion of the disc cartridge and avoid damaging the disc cartridge.

Abstract: A disk apparatus is disclosed. A movable chassis assembly having a turntable and a pickup head is detachably supported on elastic members by a stationary chassis assembly with the lock mechanism of the stationary chassis assembly engaged with lock pins disposed on the movable chassis. A holder located on the movable chassis assembly for holding a disk cartridge to load or eject the disk cartridge is transported by a loader located on the stationary chassis assembly in a predetermined transport direction.

A pair of pivoting cross links are connected at their crossings by a support pin that is engaged with a first guide slot in the stationary chassis assembly. One end of each of the pair of cross links is slidably engaged with a guide slot in the loader.
