  • Patent number: 10551256
    Abstract: A magnetostrictive torque sensor is provided that is capable of maintaining high detection accuracy, even when an excessive torque acts on a rotary shaft. The magnetostrictive torque sensor includes a magnetostrictive film 71 that is arranged on a second steering shaft 23, or a rotary shaft, having a substantially columnar shape so as to surround the second steering shaft 23 around its axis, and detects a rotational torque about the axis acting on the second steering shaft 23 based on a change in a magnetic property of the magnetostrictive film 71. Compressive stress remains on an outer circumferential surface of a sensor region 77 of the second steering shaft 23 around which the magnetostrictive film 71 is arranged. A plated layer of the magnetostrictive film 71 is arranged on the outer circumferential surface of the sensor region 77 in which compressive stress remains.

  • Patent number: 10518803
    Abstract: An articulated work vehicle with linked front and rear frames includes a joystick lever, a hydraulic actuator, a control valve, a force imparting component, a joystick displacement sensor, a steering angle sensor, and a controller. The joystick lever is operated to allow a target steering angle to be set. The hydraulic actuator is driven hydraulically to change an actual steering angle. The control valve controls flow of fluid supplied to the hydraulic actuator to eliminate deviation between the target and actual steering angles. The force imparting component imparts an assist force or a counterforce to the operation of the joystick lever. The controller controls the force imparting component so that a counterforce is imparted to the operation of the joystick lever when the joystick lever has been operated in an opposite direction from a rotation direction of the front frame based on detections of the sensors.

  • Patent number: 10518840
    Abstract: The present invention is a removable device/mechanism which is installed onto a bicycle. The installed device assists a user in pedaling in a unique fashion which removes the stresses and forces of ordinary cycling. The movement of the pedals becomes such that force is caused only during half of the circumferential movement of each pedal, similar to a step/climbing machine. The movement is achieved by placing two shafts which move alongside planes parallel to the user during motion, the two shafts being interconnected at their top and bottom ends. The bottom ends are connected to the gears and chain of the bicycle as described herein. The top ends are connected to a reverse mechanism as described herein. The combination of elements assists the user by turning an ordinary bicycle into a more relaxed use machine, allowing more people to use bicycles.

  • Patent number: 10507145
    Abstract: Powered patient support apparatuses—such as beds, cots, stretchers, or the like—include a plurality of user controls that allow a caregiver to control the steering and/or driving of one or more powered wheels from multiple different locations around the patient support apparatus (e.g. head end, foot end, and/or the sides). The control is carried out by force sensors that detect both an orientation of the applied forces and a magnitude of the applied forces. Translational and/or rotational movement is effectuated, depending upon the magnitude and direction of the forces, as well as the physical location of the applied force relative to a reference point on the support apparatus, such as the center. One or more object sensors may also be included in the support apparatus to assist in steering and/or navigating.

  • Patent number: 10501117
    Abstract: The present invention provides a vehicle including wheels, and a steering module configured to steer the wheels in one of two mutually opposite right and left directions, or in one and the other of the two mutually opposite right and left directions, respectively. In the vehicle, a caster angle is set within the range of ±3 degrees relative to a kingpin angle. Though each wheel usually forms a camber angle when steered, by setting in the wheel the caster angle beforehand within the above range, the wheel does not or is less likely to form the camber angle because the camber angle and the caster angle cancel each other. Therefore, it is possible to prevent the steering angles of the wheels from being restricted, and to prevent the deterioration of steering operability.
