  • Publication number: 20140134973
    Abstract: A non-billing instruction function terminates a transmission of billing source information for a billing process to a billing server, and when a PB receiving function detects switching of the content of a telephone call while the connection of a call is maintained, a billing source information transmitting function transmits the billing source information to the billing server. This eliminates an occasion that a service is applied or is not applied depending on an operation given by a user, thereby providing the service equally.

  • Patent number: 6910281
    Abstract: A hair drier having the capability of efficiently supplying hot air and minus ions from different outlets is provided. This hair drier has a hollow housing with an air suction inlet and an air outlet. In the housing, a fan and a heater are disposed in an air-flow channel formed between the air suction inlet and the air outlet. The air sucked in the housing by the fan is heated by the heater, and then ejected from the air outlet. The housing also has an ion-flow channel formed as an independent flow channel from the air-flow channel, and an ion outlet provided at a different position from the air outlet to eject minus ions generated by the minus ion generator. The minus ion generator is disposed in the ion-flow channel.
