Abstract: An image processing apparatus includes a placement unit that is provided on an upper surface of a housing and on which a document is placed; an imaging unit that images the placement unit from above; and a processor configured to display guidance information indicating that the document to be imaged by the imaging unit is to be placed on the placement unit, on a display unit.

Abstract: An earphone includes a housing having a space therein and having a path capable of ventilation from one end side on an external auditory canal side of a wearer to the other end side on an ambient environment side, a valve accommodated in the housing and configured to switch the path between an open state and a close state, a microphone disposed on one end side of the housing and configured to collect uttered voice of the wearer, and a control unit configured to control the open state and the close state. The control unit switches the path to the open state during a first operation in a call including an operation in which the uttered voice of the wearer is collected by the microphone, and switches the path either the open state or the close state during a second operation different from the first operation.

Abstract: An expansion valve with an improved vibration isolation mechanism includes a valve body, a valve element, a biasing member that biases the valve body toward a valve seat, an actuation rod that contacts the valve element and presses the valve element in a valve opening direction against a biasing force of the biasing member, and a vibration isolating spring that suppresses vibration of the valve element. The actuation rod is inserted into an actuation rod insertion hole in the valve body. The vibration isolating spring includes a leg spring having a base portion and a plurality of leg portions extending from the base portion. The leg spring is arranged in the valve chamber such that a center axis of the leg spring is non-coincident with a center axis of the actuation rod insertion hole.

Abstract: It is an object of the present invention to provide an expansion valve with an improved vibration isolation mechanism. Accordingly, in the present invention, the expansion valve includes a valve body, a valve element, a biasing member configured to bias the valve body toward a valve seat, an actuation rod that comes into contact with the valve element and presses the valve element in a valve opening direction against a biasing force of the biasing member, and a vibration isolating spring configured to suppress vibration of the valve element. The actuation rod is inserted into an actuation rod insertion hole provided in the valve body. The vibration isolating spring includes a leg spring having a base portion and a plurality of leg portions extending from the base portion. The leg spring is arranged in the valve chamber such that a center axis of the leg spring is non-coincident with a center axis of the actuation rod insertion hole.

Abstract: A valve piece urging member urges a valve piece toward a valve closing side, at which an opening degree of a restriction passage is reduced by the valve piece. An actuation member exerts a drive force against the valve piece in a direction of moving the valve piece toward a valve opening side, at which the opening degree of the restriction passage is increased by the valve piece. A vibration limiting member limits vibration of the valve piece in a direction, which intersects with the axial direction, by generating an urging force for urging the valve main body at a location between the valve main body and the valve piece. When the valve piece is moved beyond a predetermined displacement position toward the valve opening side, the valve piece releases the urging force of the vibration limiting member.

Abstract: A power element has a closed space provided between a first diaphragm and a second diaphragm. An interposing member is interposed between the first diaphragm and the second diaphragm. Accordingly, a size of the closed space can be optionally determined in accordance with a shape such as a thickness of the interposing member. Therefore, limitations on the size of the closed space due to a shape of the first diaphragm and the second diaphragm can be reduced. Accordingly, limitations on the size of a fluid enclosing space due to a shape of a diagram can be reduced.

Abstract: When a power element expands in a direction of a uniaxial center, a diaphragm is pressed, in the direction of the uniaxial center, against a pressing portion of a lid member fixed to a body unit. A holder member of the power element is displaced away from the pressing portion as the diaphragm further expands outward in the direction of the uniaxial center. Displacement of the holder member in the direction of the uniaxial center is transmitted to a spherical valve, thereby increasing or decreasing an opening degree of the spherical valve. Accordingly, it is not necessary to dispose a member which may cause complicated processing work for an expansion valve between the holder member and the spherical valve, e.g., a member which needs complicated welding processing work.

Abstract: A vehicular air conditioning control device that detects an outside air temperature, and calculates the time for the evaporator blower to continue to blow after the engine has been shut off, in an air conditioning system where the compressor is powered by the engine. After a given elapsed time, the control device restarts the blower fan, issues an engine startup request, and initiates refrigerant circulation by the compressor.
