  • Patent number: 12015361
    Abstract: A motor control device includes: a step-down device including a DC-output power conversion device having a first mode for outputting first voltage and a second mode for outputting second voltage lower than the first voltage; a power supply device; and a control device, and controls a motor. When a flying object takes off, the control device controls the power conversion device in the first mode. When the control device judges that flight information which is one or both of information of a motor parameter obtained along with control for the motor and information of an environmental factor relevant to the flight altitude of satisfies a predetermined condition, or when the control device has received an mode signal for which the second mode is selected on the basis of the flight information during control for the motor, the control device controls the power conversion device in the second mode.

  • Patent number: 4586144
    Abstract: A piping system surveillance apparatus has a CRT for displaying a graphic pattern of a piping system. Detectors are arranged in active construction members such as a valves, and pumps of the piping system so as to directly detect the presence/absence of fluid flow in the active construction members in accordance with operating conditions thereof. The presence/absence information of the fluid flow in non-active construction members is obtained by a CPU in accordance with logic operation of detection signals from the detectors. Data indicating the presence/absence of the fluid flow is compared with data indicating the presence/absence of the fluid flow in the construction members of the piping system in normal operation and is discriminated to be normal/abnormal. This discrimination result and the data indicating the presence/absence of actual fluid flows are displayed by the corresponding display elements of the graphic pattern on the CRT.

    Abstract: An ultrasonic imaging system comprises a transducer array including a plurality of elongated piezoelectric transducers successively arranged along a curved surface for emission of diverging beams of acoustic energy and an acoustic diverging lens affixed to the curved surface for increasing the angle of divergence of the emitted acoustic energy. The system includes a source for successively generating burst energy and means for selectively establishing a connection from the energy source to a subarray of the transducers to transmit a beam of acoustic energy therefrom and shifting the connection to the next subarray by at least one transducer in response to the generation of subsequent acoustic energy to cause the emitted acoustic energy to be angulated in an arc scan format. Means are provided for compensating for differences in energy level resulting from the differences in the path-length of the acoustic lens.
