    Abstract: A gas safety device includes: flow path through which a gas flows; ultrasonic sensor for measuring a flow rate of the gas flowing through flow path; flow rate calculator that calculates a flow rate measurement data pieces from a measurement value of the flow rate measured by ultrasonic sensor; and leakage detector that detects a minor leakage of the gas. The gas safety device further includes: pulsation recognizer that recognizes that pulsation is occurring when a fluctuation in the flow rate measuring data pieces calculated by flow rate calculator is greater than or equal to a predetermined value; and pulsating flow rate corrector that corrects, when pulsation recognizer determines that the pulsation is occurring, the flow rate measurement data piece by a predetermined value. Furthermore, when pulsation recognizer determines that the pulsation is occurring, leakage detector determines whether a leakage is present using the flow rate measurement data piece corrected by pulsating flow rate corrector.

    Abstract: According to an embodiment, a magnetic storage device includes a magnetic member, a switch element, a shift control circuit, a base current control circuit, and a controller. The magnetic member includes a portion extending in a direction. The switch element is connected in series to the magnetic member, and maintains an on state in a case where a current equal to or larger than a holding current value continues to flow in the on state. The shift control circuit shifts magnetic domains retained in the magnetic member. The controller causes the base current control circuit to supply a base current to the switching element and causes the shift control circuit to supply a shift pulse current a plurality of times.

  • Publication number: 20200352422
    Abstract: An endoscope treatment tool includes an insertion part that is insertable into a first treatment tool channel of an endoscope of an endoscope system, an operation part, and a single operation wire pulled through operation of the operation part. The insertion part includes a distal end portion that has an openable and closable grip portion, a bending portion that is able to be bent, and a connecting-portion that connects the bending portion to the operation part. The connecting-portion is moved forward and backward along a longitudinal axis of the connecting-portion and is rotated about the longitudinal axis. As the connecting-portion is moved forward and backward or is rotated, the grip portion moves forward and backward or rotates, through the operation of the operation part. As the operation wire is pulled, the grip portion is closed, and the bending portion bends in a state where the grip portion is closed.

  • Publication number: 20200294610
    Abstract: According to one embodiment, a magnetic memory puts a first magnetic domain having a magnetization direction which is the same as or opposite to a magnetic domain of a first layer of a magnetic memory line, into the first layer, based on a value of data and the magnetization direction of the first layer. When receiving a first command, the magnetic memory puts a first additional magnetic domain and a second additional magnetic domain having a magnetization direction opposite to the first additional magnetic domain into the magnetic memory line. When receiving a second command, the magnetic memory read the first and second additional magnetic domains to determine the magnetization direction of the first magnetic domain.
