Abstract: An optical deflector includes; a light transmitting portion through which a light passes; and a pair of electrodes arranged to oppose to each other with the light transmitting portion interposed therebetween. The light transmitting portion is a transparent ion conductor made of a single crystal or polycrystal. The pair of electrodes apply a predetermined voltage to the light transmitting portion to move ions inside the transparent ion conductor so as to change a traveling direction of the light passing through the light transmitting portion.

Abstract: A lithium-air battery includes: an anode that includes an anode material for absorbing and desorbing a lithium ion; a cathode that includes a cathode material with a catalyst for reducing the oxygen using oxygen as a cathode active material; and a solid electrolyte layer that includes a solid electrolyte interposed between the anode and the cathode. At least one of charge and discharge is performed in a presence of vapor-phase water. That is, the reduction of oxygen or an oxide is performed in the presence of the vapor-phase water. With this arrangement, the air battery can exhibit the effect of reducing the overvoltage.

Abstract: The control device of the three-level inverter is applied to a system having a first battery and a second battery, a drive object, and a three-level inverter having switches for three phases. The control device of the three-level inverter includes: a neutral point information acquisition unit that acquires neutral point information, a command voltage acquisition unit that acquires a command voltage vector to control a system output of the drive object to approach a command value, a setting unit that sets output patterns, which are combinations of output voltage vectors, each of the output voltage vectors indicating the phase-voltage for each of the three phases, that can be output by the three-level inverter, based on the command voltage vector, and a control unit that turns each of the switches on and off based on the output voltage vectors included in the output patterns.

Abstract: An electrical power converter includes a three-level inverter and a rotating electrical machine which includes windings. The three-level inverter includes first and second electrical storage devices, and switches. A positive side of the first electrical storage device is connected to a positive terminal of the storage battery. A negative side of the second electrical storage device is connected to a negative terminal of the storage battery. The electrical power converter also includes a connector and a controller. The connector achieves electrical connection of the electrical device with the three-level inverter and also achieves electrical connection of the electrical device with the storage battery through the neutral point. The controller works to control switching operations of the switches to achieve transmission of electrical power between the electrical device and the storage battery with the three-level inverter and the electrical device connected together through the connector.
