A method for producing a plasma display panel having a base layer including metallic oxides and agglomerated particles dispersed on the base layer includes the following steps of: forming the base layer on the dielectric layer; spreading an organic solvent in which the agglomerated particles are dispersed on the base layer to form a coating layer thereon; drying the coating layer under a reduced pressure to form an organic solvent coating film on at least the base layer; disposing the rear plate and the front plate on which the coating film is formed so as to face each other; heating the front plate and the rear plate facing each other to evaporate the coating film, dispersing the agglomerated particles on the base layer, and removing components of the evaporated coating film from the discharge space; and sealing the rear plate and the front plate from which the coating film is evaporated to each other.

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.

The present invention provides a mobile terminal and a method of executing scanning for radio signals in the case where the mobile terminal is connectable to multiple radio communication systems employing different radio communication schemes. The mobile terminal and the method can scan for radio signals transmitted from a radio base station at an appropriate timing without modifying the existing radio base station or the like. The mobile terminal includes a WLAN controller configured to cause a WLAN communication unit to execute scanning for radio signals transmitted from an access point. Scanning is executed if a scrambling code determining unit determines that a scrambling code contained in notification matches a scrambling code stored in a scrambling code information storage, and if a position determining unit determines that a certain position indicated by position information stored in a GPS position information storage is within a predetermined distance from a current position of the mobile terminal.

A high definition plasma display panel which can display a video of a higher brightness and yet can be driven at a low power consumption is realized. To this end, a plasma display panel includes front panel including display electrode formed on glass substrate, dielectric layer covering display electrode, and protective layer formed on dielectric layer; and a rear panel opposing to front panel to form a discharge space filled with discharge gas, and including an address electrode formed along a direction intersecting with display electrode, and a barrier rib partitioning the discharge space. Protective layer is formed of a metal oxide made of magnesium oxide and calcium oxide and contains zinc. In an X-ray diffraction analysis on a surface of protective layer, a diffraction angle where a peak of the metal oxide occurs exists between a diffraction angle where a peak of the magnesium oxide occurs and a diffraction angle where a peak of the calcium oxide occurs.

A car is suspended by suspension means and raised and lowered by means of a hoisting machine. Electric power supplied to a motor of the hoisting machine is controlled by an electric power converter. The electric power converter is controlled by means of a control apparatus. The control apparatus estimates a maximum value of a regenerative voltage at time of a regenerative operation of the hoisting machine when the car is running. When the estimated maximum value of the regenerative voltage reaches a predetermined voltage limit value, the control apparatus controls the electric power converter so as to stop an increase in estimated maximum value of the regenerative voltage.

A PDP can be driven at low voltage while having a charge retention property in a protection layer, and has favorable image display properties. Additionally, the PDP prevents the occurrence of discharge delay and realizes high-quality image display by performing favorable high-speed driving in a high definition PDP. To achieve this, a surface layer (8) is formed to a film thickness of 1 μm in an oxygen atmosphere having an oxygen partial pressure of 0.025 Pa or more, the surface layer (8) is provided on a face of a dielectric layer (7) on a discharge space side. Furthermore, MgO particles (16) are dispersed on a surface of the surface layer (8). The surface layer (8) has the effects of protecting the dielectric layer (7) from ion bombardment during discharge, reducing the firing voltage, and preventing excessive electron loss. Also, the MgO particles (16) have a high initial electron emission property.
摘要:
While a voltage value of the battery detected by a battery voltage-detecting part is less than a predetermined threshold voltage value for determining a low voltage state, a rotation sensor malfunction-detecting part stops calculating a vehicle speed and uses the vehicle speed calculated at a time immediately before a time when a voltage value of a battery becomes less than the threshold voltage value for determining the low voltage state, for detecting malfunction in a rotation sensor. Thereby, even if noises due to a voltage fluctuation in the battery mix with the rotation signal from the rotation sensor, since the rotation sensor malfunction-detecting part does not calculate the vehicle speed during a period of time when the voltage value of the battery detected by a battery voltage-detecting part is less than the threshold voltage value for determining the low voltage state, the vehicle speed is not miscalculated based on the rotation signal including noises, and the malfunction in the rotation sensor can be precisely detected.
