Abstract: An ultrasound diagnostic system is an ultrasound diagnostic system that performs diagnosis by moving an ultrasound probe by a robot. The system includes an arm section configured to hold the ultrasound probe, a motor section configured to move the arm section, an amplifier section configured to supply power to the motor section, a robot control section configured to output a control signal to the amplifier section, and a monitoring section configured to monitor states of respective sections constituting a system and shift to a predetermined safety state when an abnormality occurs in any of the respective sections.

Abstract: A robot device includes an arm holding a probe of an ultrasonic diagnostic device and a force sensor provided on the arm, supports a manual operation of the probe by an operator based on a signal from the force sensor, operates the arm to automatically operate the probe based on an instruction of the operator, and includes a storage device and a control device. The storage device stores a position and a posture of the probe for each point among multiple random points by the manual operation. The control device interpolates a trajectory between the multiple points stored in the storage device, and operates the arm such that the probe moves along the trajectory in the automatic operation and can stop at a desired position between the multiple points based on the instruction of the operator.

Abstract: A recording apparatus according to an aspect of the invention includes a sheet feeding cassette that can accommodate a stack of recording materials; a pick-up roller that comes into contact with the top recording material of the recording materials accommodated in the sheet feeding cassette to feed the recording material; a roller holder that is supported at a base end so as to be rotatable and has the pick-up roller at a tip, the pick-up roller being pressed against the recording material; and a lever that is supported at a base end so as to be rotatable and has a pressing portion at a tip, the pressing portion being pressed against the recording material. The lever is disposed on the roller holder and is supported coaxially with the roller holder.

Abstract: A hinge includes a tubular base part being attached to a main body or an open/closed body, a rotation body being attached to the main body or the open/closed body, which is not attached to the base part, and supported on side wall end parts of the base part opposed to each other for rotation, the rotation body having a cam part, a wedge body being reciprocatably housed in the base part and having a slope for coming in sliding contact with the cam part when the rotation body rotates, an elastic member being housed in the base part for urging the wedge body toward the side of the rotation body, a sliding contact face being formed on the side of the wedge body from a rotation axis of the rotation body on an inner wall of the base part and bent to a concave corresponding to a parallel move path of a line almost parallel with the rotation axis, and a sliding contact part being formed in the rotation body for coming in sliding contact with the sliding contact face when the rotation body rotates.
