摘要： A dispenser has a seal disk (30), a valve member (40), a plunger guide block (50), a motor (3), which rotates a cam-follower guide block (60), and an end cam (5). The seal disk (30) has communication holes (31), (32) and a sliding surface (33). The valve member has a sliding surface (41), three plunger holes (42) and three plungers (80) inserted in the plunger holes. The cam-follower guide block (60) has three guide holes (62) that receive cam followers, which each have a body (70) with a ball (75) within a recess (71). The ball (75) contacts the cam surface (5A) of the cam (5) which causes the cam followers and plungers (80) to move back and forth parallel to the dispenser axis. The coefficient of friction between the ball and the recess is less than that between the ball and the cam surface (5A).

摘要： The liquid discharging device includes a driving mechanism that drives a needle, a measurement plunger member and an inlet valve members that are concentrically-arranged inside a container. The driving mechanism includes: a piezoelectric-element support plate to which piezoelectric elements are attached; a spring for biasing the piezoelectric-element support plate toward a discharge outlet; and a control device adapted to control the piezoelectric elements separately. The piezoelectric-element support plate includes: a base end to which first end sides of the piezoelectric elements are fixed; a drive unit to which second end sides of the piezoelectric elements are fixed; and a displacement expanding portion expanding and outputting a displacement of the drive unit, the drive unit being displaced in conjunction with a expansion and contraction driving of the piezoelectric elements. Since the three members can be driven by the two piezoelectric elements, a driving at high speed can be realized and the liquid discharging device can be easily downsized.

摘要： This invention relates to a continuously operable hydraulic device usable as either a hydraulic pump or a hydraulic motor, including a plurality of unit hydraulic devices each having a pair of plungers. Operational association between these unit hydraulic devices makes it possible to discharge fluid at an accurate flow rate continuously or by a predetermined value, or to supply the fluid to rotate a driven component. Four pairs of plungers 51 and 56 are inserted into a port block 20 having a sucking port 25 and a discharge port 26 with the end faces thereof being opposed to each other. These plungers 51 and 56 are moved along a pair of cam surfaces 68A and 68B of a cam 68 by cam followers 69 and 70 which are connected to the plungers 51 and 56 via plunger driving shafts 73 and 75. These pairs of plungers 51, 56, the cam followers 69, 70 and the like constitute the unit hydraulic device 95. The unit hydraulic devices 95, in case of being as the hydraulic pump, are operated in operational association with the driving of the cam 68, and, in case of being as the hydraulic motor, are operated as the rotation of the cam 68 by the supplies of the fluid to spaces formed between the plungers 51 and 56.

摘要： A piezoelectric drive device 2 includes cases 4 and 5 and a drive device body 6. The drive device body 6 includes a displacement expanding plate 10, a biasing unit 15 and piezoelectric elements 17 and 18. The displacement expanding plate includes a body 110 biased to rotate by the biasing unit 15, and a displacement expanding portion 120 expanding a displacement when the piezoelectric elements 17 and 18 are expanded to be displaced relative to the body in a direction perpendicular to an expanding direction of the piezoelectric elements. In a state where no voltage is applied to the piezoelectric element, a first driven object 31 is moved by the body that is biased by the biasing unit. When a voltage is applied to the piezoelectric element 17, a second driven object 32 is moved by the displacement portion 120. When the voltage is further applied to the piezoelectric element 17 in a state where the second driven object 32 abuts on an object such that the displacement of the displacement expanding portion is expanded, the body 110 and the first driven object 31 are moved against a biasing force of the biasing unit in a direction opposite to a biasing direction of the biasing unit.
