摘要:
The present invention provides a method for producing an activated carbon for an electric double layer capacitor, with which the wettability of a carbon material with an alkali activator is improved, thereby improving contact efficiency between the carbon material and the alkali activator and efficiently promoting reaction between the carbon material, which is a starting material and the activator. The method comprises adjusting a carbon material as it is or after having been calcined to produce a carbon powder having an average particle diameter of 0.5 to 15 μm, oxidizing the carbon powder to contain 3 percent by mass or more of oxygen, and activating the oxidized product with an alkali activator.

The present invention provides a process for producing an activated carbon having a small average particle diameter, a uniform particle size and a relatively large specific surface area suitable for an electric double layer capacitor electrode, in an easy and cost effective manner. The process comprises calcining an easily graphitizable carbon material such as petroleum coke or coal coke, used as the raw material under an oxidizing gas atmosphere, adjusting the particle size of the carbon material, and then activating the carbon material. The use of the activated carbon produced by the process of the present invention in an electrode can provide an electric double layer capacitor having a large capacitance per unit volume.

When a user performs a short-press manipulation to A button or B button, a vehicle ID associated with either A button or B button having received the short-press manipulation is specified based on a button-vehicle correspondence table. Charge status information of a battery of a vehicle corresponding to the above associated vehicle ID is acquired from the vehicle. Thereby, the display device displays the acquired charge status information or the electric power supply is started to the battery of the vehicle corresponding to the vehicle ID.

Chargers are connectable with vehicles. An electric supply controller controls a switching circuit to connect an electric power supply line to one of the chargers. A storage unit of the electric supply controller associates information on a priority to each of the vehicles and stores the associated information therein. When the vehicles are simultaneously connected to different chargers, a control unit of the electric supply controller controls the switching circuit to connect the electric power supply line preferentially to one of the different chargers. The one of the different chargers is connected to one of the vehicles assigned with a highest priority.

Desired data can be easily retrieved from material image data associated with video data. For material image data associated with video data, character strings contained in relevant material images are extracted, and keywords input to keyword input parts of a user interface are matched with the extracted characters to retrieve data of the relevant material images. The retrieved material images are changed in size according to their importance before being displayed on a screen.
