Abstract: In this shift device, in a case in which an external force has acted on a lever when an operating mechanism is causing the lever to pivot, a clutch mechanism permits rotation of a first detent plate with respect to a second detent plate, such that pivoting of the lever is permitted. Note that a restraining mechanism urges the lever toward a shift position. This enables to the restraining mechanism to urge the lever separately to the clutch mechanism, thereby enabling the degrees of freedom for setting a biasing load on the lever by the restraining mechanism to be increased.

Abstract: A feedback control device that takes information regarding a control deviation between a measured value and a desired value of a controlled object as input, and outputs a manipulated variable for the controlled object, includes: a first control unit that takes information regarding the control deviation as input, and outputs a manipulated variable for the controlled object; a second control unit that takes information regarding the control deviation as input, and that includes a learning control unit in which a parameter for outputting a manipulated variable for the controlled object is determined by machine learning; and an adder that adds a first manipulated variable output from the first control unit and a second manipulated variable output from the second control unit. A manipulated variable from the adder is output to the controlled object, and the second control unit includes a limiter that limits the second manipulated variable.

Abstract: Back projection voxels smaller in size than forward projection voxels are created. Back projection is performed by the use of computed pixel values and measured pixel values at intersection points between straight lines connecting an X-ray source with the centroids of the back projection voxels and an X-ray detection panel.

Abstract: A photoacoustic apparatus includes a light irradiation unit configured to irradiate a subject with light, a reception unit configured to convert an acoustic wave generated from the subject into an electric signal, a processing unit configured to acquire image data using the electric signal, and a display control unit. The processing unit acquires first image data by a first image generation method using the electric signal, and acquires second image data by a second image generation method different from the first image generation method using the electric signal. The display control unit sets, as a difference region, a region in which difference image data between the first image data and the second image data has an image value within a predetermined numerical range, and causes image data in which the difference region and another region are distinguishable from each other to be displayed on a display unit.

Abstract: During an incompressible fluid movement, three consecutive times during the movement of the fluid are called first, second, and third times in time order, calculation is performed with two different types of lattices for the first and third times and for the second time. Momentum and mass density at the first time are temporally developed to the third time in accordance with a conservation law by using an upwind velocity field. A pressure at the second time is determined so that a velocity field derived from momenta at the third time satisfies an incompressibility condition, and the field at the third time is corrected by adding a change in momentum caused by a pressure term using the determined pressure. This prevents pressure vibration and avoids the complexity of advective term calculation.
