Abstract: A recording apparatus includes a recording head having discharge orifices arranged on a discharge orifice surface, a cap, a wiper, and a moving unit that moves the wiper in a first direction. When the cap covers the discharge orifice surface, a first member is disposed at an inside wall of the cap at a position near a first side of a region having the discharge orifices, and a second member is disposed at another inside wall of the cap at a position near a second side of the region having the discharge orifices. The first side faces in a direction opposite to the first direction and the second side faces in the first direction. In a direction normal to the discharge orifice surface, a distance between the second member and the discharge orifice surface is smaller than a distance between the first member and the discharge orifice surface.

Abstract: A liquid discharge apparatus includes a discharging unit configured to be capable of discharging a plurality of kinds of liquids onto a medium, and a waste liquid tank including a storage part configured to store a waste liquid of the liquid. The waste liquid tank includes a first inflow port and a second inflow port from which the waste liquid flows into the storage part, and a restriction portion located between the first inflow port and the second inflow port, and configured to restrict movement of the waste liquid in the storage part.

Abstract: A wave receiving mechanism includes: a shaft driving a hydraulic pump; and a wave receiving member including an arm and wave receiving plate, the arm unrotatably attached to the shaft, the plate being at the arm receiving a wave force, the wave receiving member swinging about the shaft by receiving the wave force and turning the shaft turn. The arm includes first and second arm portions, and a bendable portion, the first arm portion unrotatably attached to the shaft, the second arm portion being at the plate, the bendable portion coupling the first and second arm portions. When a swing angle of the first arm portion is less than a first predetermined angle, the bendable portion makes the arm portions swing integrally. When the swing angle of the first arm portion is the predetermined angle, the bendable portion allows the second arm portion to bend relative to the first.

Abstract: A wave power generation system includes: a hydraulic pump device configured to operate by force of a wave to discharge an operating liquid to a main passage; a hydraulic motor device configured to be rotated by the operating liquid flowing through the main passage; a power generator configured to be driven by the hydraulic motor to generate electric power; and a heat exchanger device configured to perform heat exchange of the operating liquid. The heat exchanger device includes a heat exchange motor device connected to the main passage through a sub passage and configured to be operated by the operating liquid introduced through the sub passage, a refrigerant pump device driven by the heat exchange motor device and configured to suck and discharge a refrigerant liquid, and a heat exchanger to which the refrigerant liquid discharged from the heat exchange pump device and the operating liquid are introduced.

Abstract: A wave receiving plate is pivotably supported by a support device in the wave force generation system and includes a flexible plate in at least a part of the wave receiving plate.

Abstract: A wave power generation system includes a wave receiving member, ram cylinder hydraulic pump device, change value sensor, accumulator device, hydraulic motor, power generator, and controller. The member is arranged near a virtual reflection surface that reflects a coming incident wave. The controller sets a torque command used when the generator generates electric power. Based on a differential value of a change value detected by the sensor and changes in accordance with a swing amount of the member, the controller determines whether the member is swinging toward a first or second side in a swing direction. When the controller determines the member is swinging toward the second side by receiving force of a reflected wave reflected by the virtual reflection surface, the controller changes the torque command from the command set when the controller determines the member is swinging toward the first side by receiving force of the incident wave.
