Patent number: 10122164Abstract: A current path of a first transistor is connected in series to a communication line. When the electric current through the current path of the first transistor becomes equal to or greater than a set electric current, a current-limiting controller limits the electric current through the current path by controlling the first transistor to increase the resistance of the current path. When the end-to-end voltage of the current path of the first transistor becomes equal to or greater than a set voltage, a load limiter switches the first transistor off.Type: GrantFiled: May 14, 2013Date of Patent: November 6, 2018Assignee: Mitsubishi Electric CorporationInventors: Takuya Mukai, Yoshiaki Koizumi

Patent number: 9935784Abstract: The lower-level information acquirer searches a lower-level network, and acquires lower-level addresses for air-conditioning devices that are connected to the lower-level network. A database generator searches an upper-level network, and generates a database of upper-level addresses of air-conditioning devices that are connected to the upper-level network. An address assigner references the database generated by the database generator, and assigns vacant addresses existing among the upper-level addresses of the upper-level network to air-conditioning devices that are connected to the lower-level network. The table generator generates an address conversion table for converting the upper-level addresses assigned by the address assigner to lower-level addresses acquired by the lower-level information acquirer.Type: GrantFiled: February 21, 2013Date of Patent: April 3, 2018Assignee: Mitsubishi Electric CorporationInventors: Hiroaki Kotake, Yoshiaki Koizumi, Takuya Mukai
