  • Publication number: 20040129778
    Abstract: A cashless automatic vendor system comprises a portable communication terminal which enables a user to dispense with troublesome operations and to execute the cashless operation of even an existing automatic vendor. An automatic vendor (1) issues a settlement request code for requesting the settlement of a selected commodity on the basis of user's operation. A center apparatus (3) processes settlement on the basis of the settlement request code received from the automatic vendor (1) via a cellular phone terminal (2), processes the settlement request code as predetermined to generated a sale permission code, and transmits it to the cellular phone terminal (2). The automatic vendor (1) reads the sale permission code displayed on the display section of the cellular phone terminal (2) and controls commodity sale on the basis of the sale permission code.

  • Patent number: 6678482
    Abstract: An object of the invention is to make an exact judgment on suitability of a replaceable component such as a toner supplying container with use of an existing mechanism of an image forming apparatus, without additionally providing a data storage component designed for a consumable product which is detachably attached to the apparatus, or a data reading component to be placed in the image forming apparatus main body. In an incorporated control section, a specific part of a replaceable component, which is placed on an original platform prior to being loaded into the apparatus, is optically scanned to read image information, and, based on the reading result, whether or not the replaceable component is suitable for the image forming apparatus is judged.

  • Publication number: 20040002365
    Abstract: An information transmission method and a system capable of transmitting information without requiring a troublesome operation and at a low cost is provided. A portable communication terminal such as a cellular phone, a PHS or the like capable of making a telephone call and performing communications over a telephone line changes an image to be displayed on a display portion with time to transmit information to an information-receiving device. The information-receiving device receives a change in display of the image on the portable communication terminal by a receiver portion and recognizes the information from the received change in display (e.g., a display interval, etc.).

  • Publication number: 20030231005
    Abstract: There is provided a battery control apparatus that, when the battery temperature is low, repeats the charge and discharge of a battery on a short cycle such that the state of charge (SOC) of the battery lies in the range of 30 to 40% if the present SOC is less than 50%, and repeats the charge and discharge of the battery on a short cycle such that the SOC lies in the range of 50 to 60% if the present SOC is equal to or greater than 50%, thus increasing the temperature of the battery. Therefore, it is possible to increase the battery temperature in an efficient manner, and to prevent the available input-output power of the battery from being reduced due to a decrease in the battery temperature.
