    摘要: A calculator or an electronic control unit (ECU) calculates an instruction value of a column assist torque and a rack assist torque output from a column actuator, or a column motor, and a rack actuator, or a rack motor, based at least on a torsion torque. The calculator includes a base assist controller, a stabilization controller, and an adder. The base assist controller individually or commonly calculates a base assist torque based on the torsion torque. The stabilization controller individually or commonly calculates a stabilization torque for stabilizing a steering system. The adder performs addition of the base assist torque and the stabilization torque.

    摘要: An excellent photosensitivity is exhibited by a protein including, at a position or positions corresponding to one or two or more positions selected from the group made of the following (1) to (3) in a first amino acid sequence represented by SEQ ID NO: 1: (1) positions 39, 94, 98, 102, 110, 113, 114, 162, 224, 225, 230, 231, and 235, (2) positions 53, 61, 68, 74, 76, 80, 130, 137, 194, 195, 198, 200, 204, 205, 209, 210, 253, and 254, and (3) positions 46, 83, 84, 87, 90, 91, 116, 117, 120, 124, 139, 142, 143, 146, 173, 214, 216, 217, 238, 242, and 245, an amino acid residue different from that in the first amino acid sequence, and that has channel activity.

    摘要: A positioning control device of an actuator provided with a strain wave gearing has a full-closed control system for feeding back a position of a load shaft, and driving and controlling a motor so as to position the load shaft at a target position. The full-closed control system has an H∞ compensator designed so that, when a generalized plant having angular transmission error in the strain wave gearing as a disturbance input is assumed, an H∞ norm of a transfer function from the disturbance input of the generalized plant to an evaluation output is a predetermined value or less. Mechanical vibration during positioning response caused by angular transmission error in the strain wave gearing can be reliably suppressed.

    摘要: In a position measuring apparatus, a correspondence point detector detects, for each set of images at a respective one of time instants, correspondence points from the respective images of the set, where the correspondence points are points on respective image planes representing the same three-dimensional position. A projection point calculator calculates a projection point of each of the correspondence points detected at the respective time instants onto each of a plurality of common planes set at different depthwise positions in a world coordinate system using preset camera parameters. A reconstruction point calculator calculates a point at which distances to a plurality of rays each connecting the projection points of the correspondence point on a respective one of the image planes onto the plurality of common planes are minimized, as a reconstruction point representing a three-dimensional position of the correspondence point.
