    摘要： A droplet discharge head includes a lower housing, an upper housing, a nozzle plate, a shaft-shaped member, and a driver. The lower housing includes a flow channel. The upper housing is on the lower housing and detachable from the lower housing. The nozzle plate is on a lower surface of the lower housing. The shaft-shaped member includes a valve element at a tip end of the shaft-shaped member to open and close a nozzle orifice of the droplet discharge head. The shaft-shaped member is reciprocatable in the upper housing. The driver is disposed in the upper housing and reciprocates the shaft-shaped member in an axial direction of the shaft-shaped member. The shaft-shaped member is movable in the axial direction of the shaft-shaped member such that a length of the tip end of the shaft-shaped member protruding from the lower surface of the upper housing is shortened.

    摘要： This camera actuator is provided with a stationary-side member, a movable-side member which is provided to the stationary-side member in a displaceable manner and which holds a lens section, and a drive section which displaces the movable-side member in a plane including a first direction and a second direction which is perpendicular to the first direction. The movable-side member has a magnet affixation section for affixing a magnet section thereto such that the magnet section faces the stationary-side member, the magnet section being used for detecting the position of the movable-side member in either the first direction or the second direction. The surface of the magnet affixation section, to which the magnet section is mounted, is formed from metal.

    摘要： A plant monitoring and control apparatus having a function to simulate an object to be monitored and controlled for verifying healthiness of a control processing unit is provided with an input separating operation unit and an output separating operation unit which separate DI data and DO data handled by the control processing unit by transforming the DI data and the DO data into a label format differing from a label format of PDI data and PDO data which are related to input and output between the object to be monitored and controlled and the plant monitoring and control apparatus. In test mode, a switching unit switches an input device of the control processing unit and an output device thereof to a simulator unit provided within the plant monitoring and control apparatus.

    摘要： This camera actuator comprises: an optical path bending member; a lens unit disposed at a subsequent stage of the optical path bending member; a first actuator that is disposed near the optical path bending member and displaces the optical path bending member; and a second actuator and a third actuator that are disposed near the lens unit so as to be apart from each other in a first direction, and that respectively displace the lens unit in a second direction and a third direction that are orthogonal to the first direction and orthogonal to each other. As a result, the present invention provides a camera actuator capable of improving the degree of freedom of design around the optical path bending member.
