A mobile terminal includes: a first manner of wireless communicator for conducting wireless communication with a client terminal; a second communicator for conducting wireless communication with a network (NW1); storage for storing data; and communication control for causing data to be transmitted between communicators. The communication control causing data received via the second communicator to be stored when a client terminal is in a state in which the client terminal does not receive data, and causes the stored data to be transmitted by the first communicator when the client terminal is in a state in which the client terminal receives data. Further, the communication control causes the data received via the first communicator to be stored when wireless communication with the network is not possible, and causes the stored data to be transmitted by the second communicator when wireless communication with the network is possible.

An HGW mobile device 20 can perform data communication on the basis of a plurality of wireless communication methods with different theoretical maximum transmission speeds, i.e., on the basis of a mobile wireless communication method and a wireless LAN communication method. Since the HGW mobile device 20 is provided with a mobile wireless communication unit 210 and a wireless LAN communication unit 250, it is able to relay data transmission between an external network 10 and a client terminal 30. A transmission speed initializing unit 230 sets a value according to a theoretical maximum transmission speed of the wireless communication method with the slower theoretical maximum transmission speed, i.e., the theoretical maximum transmission speed of the mobile wireless communication method, as an initial transmission speed for the wireless LAN communication unit 250 to first start wireless LAN communication with the client terminal 30 on the basis of the wireless LAN communication method.

It is intended to provide a power generating apparatus of renewable energy type and an operation method of the power generating apparatus, which can achieve both variable speed operation and grid connection without a frequency converting circuit and which uses a hydraulic transmission. In the power generating apparatus of renewable energy type 1, renewable energy received via a blade 4 is transmitted to a synchronous generator 20 via a rotating shaft 8 and a hydraulic transmission 10. The synchronous generator 20 is driven by a hydraulic motor 14 of the hydraulic transmission 10 to generate power. The synchronous generator 20 is connected to a grid without a frequency converting circuit and the power generated by the synchronous generator 20 is supplied to the grid 50. The power generating apparatus 1 is also provided with a transmission controller 40 which controls the hydraulic transmission 10. The transmission controller 40 controls the hydraulic transmission 10 in a normal operation mode to adjust displacement of each of a hydraulic pump 12 and the hydraulic motor 14 such that the rotating shaft 8 rotates at a rotational speed that is variable with respect to flow speed of the renewable energy while keeping a rotational speed of the synchronous generator 20 at a synchronous speed based on frequency of the grid 50 during normal operation of the power generating apparatus.

A plasma display panel has high definition, high luminance, and low power consumption. In the plasma display panel, the front panel is provided thereon with display electrodes, a dielectric layer, and a protective layer. The display electrodes are formed on the front glass substrate. The dielectric layer coats the display electrodes, and the protective layer is formed on the dielectric layer. The rear panel is provided thereon with address electrodes and barrier ribs for partitioning the discharge space in the direction crossing to the display electrodes. The front and rear panels are opposed to each other with a discharge space therebetween filled with a discharge gas. The protective layer on the dielectric layer includes an underlying film, and aggregated particles adhered on the underlying film, the aggregated particles being formed by aggregating crystal grains of magnesium oxide. The underlying film contains metal oxides composed of at least two oxides selected from magnesium oxide, calcium oxide, strontium oxide, and barium oxide. According to an X-ray diffraction analysis of the surface of the underlying film, in a specific plane direction, the metal oxides have a diffraction angle peak between the minimum and maximum diffraction angles of simple substances of the oxides composing the metal oxides.
