  • Patent number: 7028533
    Abstract: Measurements are obtained by a computing unit based on an output Vh from an indirectly-heated constant-temperature controlling flow rate measuring section (16) and an output Vout from a two-constant-point temperature difference detecting flow rate measuring sections (18a, 18b). In the flow rate measuring section (16), a heating element (163) is feedback-controlled based on a detected temperature by a heat sensing element (162) to obtain an output Vh based on the feedback-controlled condition. An output Vout is obtained from flow rate measuring sections (18a, 18b) based on the detected temperature difference between a heat sensing element (182) disposed on the liquid-flow-direction upstream side of the flow rate measuring section (16) and a temperature sensing element disposed on the downstream side.

  • Patent number: 7024390
    Abstract: The invention solves the inconvenience that a customer would experience when his/her electronic wallet was lost or broken down. A backup condition testing means tests predefined backup conditions to determine whether to make a backup, when an electronic wallet device communicates with any other device to transfer monetary data. When the backup condition testing means has determined to make a backup, a backup data sending means sends a predetermined set of backup data collected from the electronic wallet device. A backup data management means receives the backup data from the backup data sending means and saves the received data into its backup database. In this way, the proposed system automatically saves backup data of the electronic wallet device when any backup condition is met. This mechanism permits the customer to have an alternative electronic wallet device to be promptly issued when his/her electronic wallet device is lost.

  • Patent number: 7014228
    Abstract: A door closer includes a striker, a latch mechanism, and an actuator that brings the striker into a standby position when the actuator performs a standby action and, brings the striker into a closed position when the actuator performs a closing operation. After the striker is located at the standby position and engaged with the latch mechanism, the striker is moved to the closed position, thereby closing the trunk lid with respect to the vehicle body. Between the actuator and the striker, the striker is held at the standby position when the actuator performs the standby action in a normal state. When a switching operation is performed, the striker is allowed to move to the closed position even when the actuator 30 performs the standby action.
