Patent number: 10014809Abstract: A motor driving apparatus includes a driving circuit that drives a motor based on a driving instruction signal at a first state of the first state and a second state which are binarized, a current feedback circuit including a latch circuit, and a controller that outputs the driving instruction signal and a current command signal. The latch circuit latches a third state of the third state and a fourth state which are binarized if a motor current value exceeds a current command value. When the driving instruction signal becomes the second state, the latch circuit releases the latching of the third state and outputs a signal of the fourth state. The controller outputs the driving instruction signal of the second state along with the current command signal so as to release the latching of the latch circuit when outputting the current command signal with the current command value changed.Type: GrantFiled: January 25, 2017Date of Patent: July 3, 2018Assignee: KABUSHIKI KAISHA TOKAI RIKA DENKI SEISAKUSHOInventor: Kenji Murata

Patent number: 9777757Abstract: A fixture includes a base portion and a pair of holding portions on the base portion. Each holding portion include a clamping portion for clamping an object, and a head portion on the clamping portion side opposite to the base portion side. Each head portion includes a through-hole for a fastening member for adjusting a gap between the holding portions. The rigidity of the clamping portions is smaller than the rigidity of the head portions, with respect to deformation caused by the fastening member. The distance from the base portion to end portions of the holding portions in a plane orthogonal to the axial direction of the object is determined according to the tolerance prescribed for the object. The gap when external force is not being applied by the fastening member is determined according to an allowable amount of stress to be applied to the object.Type: GrantFiled: March 2, 2016Date of Patent: October 3, 2017Assignee: OMRON CorporationInventor: Kenji Murata
