  • Patent number: 5570596
    Abstract: A washing machine includes a dehydrating tub whose interior is divided by rotational angle detecting elements into a plurality of circumferential areas. A period of time required for each area to pass a water pouring location is cumulated by a timer function of a microcomputer in a rinse-with-dehydration operation in which the dehydrating tub is rotated with water being supplied to the tub, A quantity of water poured into or contained in laundry in each area is determined on the basis of a cumulated value so that insufficiency in the quantity of poured water due to rotational unevenness of the dehydrating tub is solved.

  • Patent number: 5469719
    Abstract: A full automatic washing machine includes an outer tub, a rotatable tub rotatably mounted in the outer tub, an agitator rotatably mounted in the rotatable tub and an electric motor for driving the rotatable tub and the agitator. The volume of clothes accommodated in the rotatable tub is detected. A control circuit controls either a stored-water rinse mode in which the clothes are rinsed with water being stored in the rotatable tub or a rinse-with-dehydration mode in which the clothes are rinsed and dehydrated with the water supplied into the rotatable tub. The stored-water rinse mode is selected when the detected volume of clothes is large. The rinse-with-dehydration mode is selected when the detected volume is small.

  • Patent number: 5150713
    Abstract: In a shock wave therapy apparatus, shock wave irradiation conditions, such as the number of shock wave irradiations, a pulse rate, a driving voltage, and the number of pause shots, are set by a setting unit in accordance with the position and size of a calculus in a subject which are acquired by an ultrasonic tomographic image. Irradiation of shock waves by a shock wave applicator starts according to the set shock wave irradiation conditions, and the ultrasonic tomographic image and the corresponding irradiation condition data are displayed on a display unit during shock wave irradiation. When the number of shock wave irradiations reaches the number of pause shots, the shock wave irradiation is temporarily stopped. Then, the focus point of a shock wave is moved on the basis of the ultrasonic tomographic image and irradiation condition data displayed on the display unit. When the shock wave irradiation is completed, a therapy record of the subject is printed out by an output unit.

  • Patent number: 5103805
    Abstract: A shock-wave curative apparatus is provided with a second imaging probe, which is disposed outside a shock-wave applicator, in addition to a first imaging probe. The first imaging probe collects mode data of a human body, and is movably located at substantially the center of the shock-wave applicator. The second imaging probe is located outside the shock-wave applicator, and manually collects mode data of the human body from the outside of the shock-wave applicator. The first and second imaging probes are connected through a select switch to a mode data processing section. The select switch selectively makes either of the first and second imaging probes ready for use. The processed mode data is displayed by a display means.

    Abstract: A shock wave lithotrity apparatus comprises an applicator which includes a first transducer for generating ultrasonic waves and for converging the ultrasonic waves on a focal point to treat an object, a second transducer for generating ultrasonic waves at a low level for echography, and a water bag for transmitting the ultrasonic waves to the object. A lithotrity unit and a B-mode imaging unit are respectively connected to the first and second transducers. When a position mode is selected, the second transducer is driven by the B-mode imaging unit and the echography is displayed and the first transducer is driven by the lithotrity unit at a low voltage to detect the intensity of the echo signal. The degree of focus-calculus matching is calculated based on the intensity. The operator adjusts the position of the first transducer by referring to the echography and the matching degree.

  • Patent number: 4962754
    Abstract: A shock wave treatment apparatus has a shock wave applicator including a shock wave transducer for forming a focusing region of a shock wave for destroying an object to be destroyed in an object to be examined, and an ultrasonic transducer for transmitting/receiving an ultrasonic wave and acquiring ultrasonic tomographic image information. The shock wave applicator is aligned with the object to be destroyed, such that an overlap degree between a focusing region of the shock wave and the object to be destroyed is discriminated by an overlap degree discrimination circuit. When the calculation result of the overlap is smaller than a predetermined value, control is performed not to generate a shock wave. On the other hand, the shock wave application is mechanically aligned with the object, such that a support device supporting the applicator is operated so that a focal point position of the shock wave in the object to be examined can be moved to coincide with the object to be destroyed.

  • Patent number: 4779623
    Abstract: A system for both measuring the sound velocity of tissue in an object and simultaneously providing a real-time B-mode image of the object. The system alternately image scans the object and cross scans the object so that a B-mode image of the object can be displayed while the object is being cross scanned by intersecting beams. By measuring the propagation times and displaying both a B-mode image of the object along with an image representing the cross scan signals, the user can view and correct errors caused by the reflection of echos waves from undesired reflection points, such as blood vessels.
