Abstract: An image processing device includes a target image acquirer that acquires a target image, a target index value calculator that calculates a target index value for a subregion that is a portion of the target image, a material image acquirer that acquires material images arranged in chronological order, an index value calculator that calculates, in chronological order, an index value for a material subregion that is a portion of the material images, a cycle pattern generator that generates a cycle pattern fitting a chronological change in the calculated index value, and a change detector that calculates a correction index value that is a value in the-cycle pattern at a capturing date and time at which the target image is captured, and determines that a change occurs in the material subregion when a difference between the target index value and the correction index value is greater than a threshold.

Abstract: There is realized a piezoelectric/electrostrictive device of a laminated type from which a large displacement is obtained and which is highly reliable over a long period. A laminated piezoelectric/electrostrictive device 1 has: a laminated columnar article 10 constituted by alternately laminating a plurality of piezoelectric/electrostrictive layers 14 and inner electrode layers 18, 19; and a pair of outer electrodes 28, 29 disposed on a peripheral surface of the laminated columnar article 10 to connect layers having the same polarity to each other among the inner electrode layers 18, 19. This laminated piezoelectric/electrostrictive device 1 is characterized in that interfaces 2a, 2b having a relatively low interface strength as compared with the other interfaces are disposed at a specific interval among the interfaces between layers of the laminated columnar article 10.

Abstract: A planar body with a good crystallinity is grown continuously and stably when a planar body of an oxide single crystal is grown by a micro pulling-down method. A raw material of the oxide single crystal is melted in a crucible 7. A fibrous seed crystal 15 is contacted to a melt 18, and then the melt 18 is pulled down from an opening 13c of the crucible 7 by lowering the seed crystal. A shoulder portion 14A is produced following the seed crystal, and a planar body 14B is produced following the shoulder portion. In this case, differences in lattice constants between each crystal axis of the seed crystal and each corresponding crystal axis of the shoulder portion are controlled at 1% or less, respectively.
