  • Patent number: 10856852
    Abstract: An ultrasonic diagnostic system includes elements disposed around a subject to transmit and/or receive ultrasonic waves. A controller controls the elements so that some of the elements disposed in a first region transmit ultrasonic waves at a first angle to a diagnosis target in the subject, some of the elements disposed in a second region receive reflected waves of the ultrasonic waves, which are reflected from the diagnosis target at a second angle, and some of the elements disposed in a third region receive reflected waves of the ultrasonic waves, which are reflected from the diagnosis target at a third angle distinct from the second angle. An operator calculates a velocity vector of the diagnosis target using the reflected waves received by the some of the elements disposed in the second region and the reflected waves received by the some of the elements disposed in the third region.

  • Patent number: 9761472
    Abstract: The present invention provides a container opening/closing device for opening and closing a lid of a container. The container comprises a container body including an opening and the lid detachably attached to the opening. The device comprises an opening/closing mechanism including a holding portion for holding the lid and a pressing mechanism. The opening/closing mechanism opens and closes the opening by moving the holding portion between a closing position and an open position. The pressing mechanism presses a peripheral edge of the holding portion toward the container body when the opening/closing mechanism moves the lid from the open position to the closing position.

  • Patent number: 9696290
    Abstract: The interior of a fractionating tool for fractionating dioxins is packed with a purification layer and an adsorption layer. The adsorption layer includes a first adsorption layer including an activated carbon-containing silica gel layer and a graphite-containing silica gel layer, and a second adsorption layer including an alumina layer. When a solution of dioxins is injected into the purification layer and is supplied with an aliphatic hydrocarbon solvent, the solvent dissolves dioxins in the solution of dioxins and passes through the purification layer and the adsorption layer. In this process, non-ortho PCBs, PCDDs and PCDFs among dioxins are adsorbed to the first adsorption layer, and mono-ortho PCBs among dioxins are adsorbed to the second adsorption layer. As a result, dioxins are fractionated into a group including non-ortho PCBs, PCDDs and PCDFs, and mono-ortho PCBs.
