Publication number: 20110242398Abstract: A driving circuit (21) of a shape memory alloy actuator of the present invention measures by a measurement part a parameter value corresponding to a target position of a moving part that is displaced by being driven on account of the expansion and contraction of an SMA (15), which expands and contracts with temperature changes and which exhibits hysteresis in a parameter-distortion characteristic relating to the expansion and contraction, while the temperature of the SMA (15) is being raised or lowered. The driving circuit (21) sets the measured parameter value as a target parameter. The temperature of the SMA (15) is raised or lowered such that the parameter value measured by the measurement part passes the target parameter, before the crystal phase of the SMA (15) becomes a martensitic phase. Thereafter, the temperature of the SMA (15) is raised or lowered again such that the parameter value measured by the measurement part reaches the target parameter.Type: ApplicationFiled: December 8, 2009Publication date: October 6, 2011Applicant: Konica Minolta Opto, Inc.Inventors: Yasuhiro Honda, Nobuya Miki

Patent number: 7953319Abstract: In a position controller, a driving mechanism and an image pickup system according to the present invention, an operation of controlling a position of a movable member is performed by using, as a reference value, a first resistance value giving a first change point at which a resistance change rate per unit temperature change in a shape-memory-alloy member changes from a first rate to a second rate different from said first rate. Thus, the present invention makes it possible to control the position of the movable member based on a resistance of a shape-memory-alloy member, without a position sensor.Type: GrantFiled: March 31, 2008Date of Patent: May 31, 2011Assignee: Konica Minolta Opto, Inc.Inventors: Yasutaka Tanimura, Takeshi Aoi, Nobuya Miki
