  • Publication number: 20180254636
    Abstract: A photovoltaic power conditioning system (PV-PCS) outputs power generated by a photovoltaic panel. An electric vehicle power conditioning system charges an electric vehicle with power supplied from a commercial power system or the power outputted from the PV-PCS. The PV-PCS directly or indirectly receives limitation information from a server. During a limitation period in which the power to be outputted from the PV-PCS is limited, a management device obtains a suppressed power generation amount on the basis of a readily estimated power generation amount of the PV panel, and controls the PV-PCS so that charging power increases by having the suppressed power generation amount as an upper limit.

  • Patent number: 9779993
    Abstract: A method for dividing a wafer including: attaching a protective tape to a functional layer of the wafer with the adhesive layer of the tape in contact with the functional layer; and a wafer dividing step. The dividing step includes a cut groove forming step and a laser processing step. The cut groove forming step uses a blade to form a cut groove with a depth that does not reach the functional layer, resulting in part of the substrate being left along each division line. The laser processing step includes applying a laser beam to the part of the substrate left after the cut groove forming step and the functional layer of the wafer to form a laser processed groove having a depth reaching the tape. The tape is closely attached to the functional layer during the tape attaching step to prevent the adhesion of debris to the devices.

  • Patent number: 9758153
    Abstract: A control apparatus for a hybrid vehicle including an internal combustion engine, a motor, and a storage battery and which charges the storage battery with electric power generated as a result of regenerative braking and electric power generated by using an output of the engine. When a planned travel route includes a downhill section whose height difference is greater than a predetermined height difference threshold, the controller executes a downhill control operation that decreases the target remaining capacity of the storage battery. The controller increases the height difference threshold as the estimated average speed of the vehicle during travel in the downhill section increases, to thereby restrain the execution of the downhill control for a downhill section in which an increase in the remaining capacity is not expected due to a large air resistance acting on the vehicle.
