20090051136 | COAXIAL TWO-WHEELED INVERTED PENDULUM TYPE MOVING VEHICLE - The present invention provides, in connection with a coaxial two-wheeled inverted pendulum type moving vehicle, a technique which allows sudden braking without making a vehicle body to tilt significantly backward. The coaxial two-wheeled inverted pendulum type moving vehicle of the present invention comprises a pair of wheels, a chassis for supporting the pair of wheels coaxially and rotatably, wheel actuators for rotating the wheels with respect to the chassis, a vehicle body supported by the chassis, and an inverted pendulum control unit for controlling the wheel actuators so as to maintain the balanced state of the chassis. In this moving vehicle, the vehicle body is shiftable supported by the chassis in a manner that the vehicle body may shift in a direction parallel to the moving direction of the moving vehicle with respect to the chassis. The traveling body further comprises an attitude actuator for shifting the vehicle body along the moving direction of the moving vehicle with respect to the chassis, and a braking attitude control unit for controlling the attitude actuator so as to shift the vehicle body to a direction opposite to the moving direction of the moving vehicle with respect to the chassis when braking is commenced while the moving vehicle is in motion. | 02-26-2009 |
20110000948 | FILM TRANSPORT APPARATUS AND FILM TRANSPORT CONTROL METHOD - A film transport apparatus includes: an edge sensor that detects a lateral position deviation of a film; a lateral position correction device that corrects a lateral position of the film with a guide roll; a tension sensor that detects tensions applied respectively near left and right ends of the film; and a control unit that executes feedback control such that the lateral position correction device is controlled on the basis of the lateral position deviation detected by the edge sensor so that the film is located at a target position. The control unit changes the feedback control based on a left and right tension difference, which is a difference between the tension applied near the left end of the film and the tension applied near the right end of the film, the tensions being detected by the tension sensor. | 01-06-2011 |
