Patent number: 10054318Abstract: The heat medium transport paths are arranged between the first building and the second building and transport heat media that transport heat energy. A temperature distribution acquisition means acquires the temperature distribution of the heat media that have temperatures being different from each other in the heat medium transport paths and that are sequentially transported in a state of having a predetermined length in the transport direction in the heat medium transport paths. A control means receives a load request of an air conditioner of the first building, and when a heat medium having the heat energy that satisfies the load request received reaches the first building, based on the temperature distribution acquired by the temperature distribution acquisition means, the control means causes the air conditioner of the first building to take out the heat energy from the heat medium reached.Type: GrantFiled: November 18, 2013Date of Patent: August 21, 2018Assignees: OSAKA CITY UNIVERSITYInventors: Masaki Nakao, Masatoshi Nishioka, Craig Farnham, Tsuyoshi Nagahiro, Youichi Kobayashi

Patent number: 10027156Abstract: An electronic apparatus and a charging method are disclosed. An electronic apparatus comprises a battery, a charge processing module, a setting module, and a determination module. The charge processing module includes a power reception coil, a generation module, and a charging module. The generation module generates a DC voltage based on the electric power received by the power reception coil. The charging module charges the battery based on the DC voltage when the DC voltage supplied from the generation module is equal to or greater than a first threshold or is greater than the first threshold, and does not charge the battery when the DC voltage is equal to or smaller than a second threshold or is smaller than the second threshold. The setting module reduces a charging current when the determination module determines that the battery is not continuously charged after the charging module starts charging the battery.Type: GrantFiled: November 18, 2015Date of Patent: July 17, 2018Assignee: KYOCERA CorporationInventor: Masaki Nakao
