Patent number: 11979035Abstract: A wireless power transmitting apparatus is provided with: a power transmitting circuit for transmitting power for a load device to a wireless power receiving apparatus; a signal transmitting circuit for transmitting a control signal for the load device to the wireless power receiving apparatus; a signal receiving circuit for obtaining an estimated received power level indicating a level of the power transmitted from the wireless power transmitting apparatus and received by the wireless power receiving apparatus; and a control circuit. The control circuit periodically allocates time slots to wireless power receiving apparatuses for wireless power transmission. When the received power level is smaller than a threshold in a first time slot allocated to one wireless power receiving apparatus, the control circuit extends a second time slot allocated to the one wireless power receiving apparatus, the second time slot preceding or following the first time slot.Type: GrantFiled: August 19, 2019Date of Patent: May 7, 2024Assignee: OMRON CORPORATIONInventors: Kentaro Hamana, Tetsuya Nosaka, Manh Tai Nguyen, Akito Murai, Yoshiki Sugimoto

Patent number: 7017713Abstract: A mast in a conventional stacker crane is configured to extend in a vertical direction. Accordingly, the mast is not sufficiently rigid, and may swing in a running direction during running or when the running operation is stopped. An attempt to increase the rigidity results in a thicker mast, thus increasing the size of the stacker crane. In order to solve this problem, a mast is extended vertically from a lower frame and a platform that elevates and lowers along the mast wherein a ladder is extended vertically at a position opposite to the mast across the platform in a direction in which the lower frame runs, and a top of the mast and a top of the ladder is connected together via an upper frame.Type: GrantFiled: November 25, 2002Date of Patent: March 28, 2006Assignee: Murata Kikai Kabushiki KaishaInventor: Akito Tai
