  • Patent number: 10335098
    Abstract: In a panoramic imaging apparatus, a panoramic image is displayed on a monitor. The panoramic image is an image in which an overall dentition is in optimal focus, or an image in which a region of interest that is a portion of the image of the overall dentition is in optimal focus. Both images are reconstructed from frame data that has been collected by an initial first scan. Feature points of one or more teeth and a supporting portion that supports the tooth in the dentition in the panoramic image displayed on the monitor are designated. A length based on the positions of the designated feature points is measured in the panoramic image. The degree of loss in alveolar bone that supports the tooth is analyzed based on the measured length. The analysis information is provided to a dentist as check information regarding periodontal disease.

  • Patent number: 9900546
    Abstract: A monitoring system has a monitor connected to a monitoring camera and a monitoring recorder via a network. The monitor checks whether the monitoring recorder is in a recordable state or in an unrecordable state of monitoring video data, and if the monitor confirms an unrecordable state of the monitoring recorder, the monitor 3 transmits a control signal for instructing the monitoring camera to start video recording. Receiving the control signal instructing to start the video recording, the monitoring camera records the monitoring video data it takes in its own storage medium.

    Abstract: The present invention relates to a plurality windings of U phase corresponding to one magnetic pole including first and second windings wound in a short pitch winding manner. The winding starts of the first and second windings are shifted by at least one tooth. The windings are wound so that a winding angle occupied by the windings inter-slot angle from the winding start of the first winding to the winding end of the second winding corresponds to a pole angle. The windings in the V phase are disposed in the same relationship as in the U phase at the position delayed by an electric angle of 120 degrees with respect to the U phase, and those in the W phase are disposed at the position delayed by an additional 120 degrees. The outputs of the windings are then each rectified, subsequently joined together and used by adding currents.

  • Patent number: 8823333
    Abstract: Solenoid coils not interlinked by magnet flux of a rotor, increase inductance of a control coil system for controlling generated voltage using little current flow to a switch so no increase in windings of a power coil is needed. A generator with rotor having magnets and stator outside the rotor, have winding coil of the stator connected in series to solenoid coil. A power terminal is between the power and control sides of the solenoid coil and a switch controls flow of current from the power coil to the solenoid coil. By controlling ON/OFF condition of the switch disposed on the DC terminal of a rectifier connected to the solenoid coil in series, the generated voltage is controlled to a voltage set in advance, in response to a detection signal from a sensor detecting the voltage.

  • Patent number: 7059130
    Abstract: A heat exchanger is applied well to a turbo-generator system and a fuel-reforming system. The heat exchanger has porous metals disposed in a hotter area and a colder area, one to each area, and a wall separating the two areas from one another. The porous metals are merged integrally with the wall through junction layers to raise the efficiency of the heat exchanger. The porous metals in the hotter and colder areas are merged together with the opposite surfaces of the wall through junction layers buried into the porous metals. The junction layers are made of pasty joining material kneaded with a powdery metal. The junction layers over the porous metals are brought into close contact with the opposite surfaces of the wall and subjected to sintering to get the porous metals merging together with the wall.
