  • Publication number: 20190250225
    Abstract: According to one embodiment, an RF circuit includes a directional coupler, processing circuitry, and an adjuster. The directional coupler includes a first port for outputting at least a part of a traveling wave and a second port for outputting at least a part of a reflected wave. The processing circuitry is configured to calculate impedance of a load side that is viewed from the directional coupler, by using a voltage standing wave ratio based on respective outputs from the first port and the second port and a phase of the reflected wave based on an output from the second port. The adjuster is configured to adjust an output from at least one of the first port and the second port based on the impedance calculated by the processing circuitry.

  • Patent number: 10377412
    Abstract: A steering assist control system causes multiple actuator units to control an assist torque that provides assistance in steering in accordance with a turning operation on a steering wheel in a vehicle having an information presentation apparatus. The steering assist control system includes: a monitoring part that monitors the actuator units; a torque control part that reduces, in a case of a one-unit anomaly, the assist torque that results from combining output torques from all the actuator units, when the turning operation is performed on the steering wheel; and a warning control part controls the information presentation apparatus. In the case of the one-unit anomaly, the torque control part reduces the assist torque so that the assist torque is smaller than an assist torque output before the occurrence of the one-unit anomaly, every time the turning operation proceeds by a set angle.

  • Publication number: 20190212044
    Abstract: Provided is an air-conditioning apparatus configured so that a decrease in a refrigeration capacity can be suppressed without increasing the amount of refrigerant with which a refrigerant circuit is filled and that refrigerant can be suitably stored during a pump down operation. The air-conditioning apparatus includes a first on-off valve provided at a pipe between an expansion valve and a use side heat exchanger, a bypass branching from a pipe between the expansion valve and the first on-off valve and connected to a pipe at a suction-side of a compressor, and a refrigerant storage unit configured to store the refrigerant having passed through the bypass. In a pump down operation in which the compressor operates with the first on-off valve being in a closed state, the refrigerant having flowed out from the heat source side heat exchanger flows into the bypass, and then, is stored in the refrigerant storage unit.

  • Publication number: 20190194220
    Abstract: Novel tetrahydroisoquinoline derivative compounds are disclosed herein that may be used as an active ingredient for a pharmaceutical composition, and in particular, for a pharmaceutical composition useful for preventing or treating a disease or condition responsive to modulation of the contractility of the skeletal sarcomere. This may be accomplished, for example, by modulation of the troponin complex of the fast skeletal muscle sarcomere through one or more of fast skeletal myosin, actin, tropomyosin, troponin C, troponin I, and troponin T, and fragments and isoforms thereof. The tetrahydroisoquinoline derivative compounds can thus be used as an agent for preventing or treating 1) neuromuscular disorders, 2) disorders of voluntary muscle, 3) CNS disorders in which muscle weakness, atrophy, and fatigue are prominent symptoms, 4) muscle symptoms stemming from systemic disorders, and 5) dysfunctions of pelvic floor and urethral/anal sphincter muscle.
