  • Publication number: 20110205315
    Abstract: Provided is a pressure damper reducing pressure fluctuations of liquid and detecting the pressure fluctuations of the liquid. The pressure damper (1) includes: a main body portion (2), the main body portion (2) including a recessed portion (4) with an opening and a communication hole (5) which is open to an inner surface of the recessed portion (4) and communicates to an external region; a flexible thin film (7) which closes the opening for reducing pressure fluctuations of fluid (6) included in the closed recessed portion (4); and a detecting portion (10) engaged with the main body portion (2) for detecting electromotive force generated by electromagnetic induction thereby detecting relative positional change between the flexible thin film (7) and the main body portion (2).

  • Publication number: 20110169385
    Abstract: A fiscal board receiving case is provided. A management board receiving case includes a case main body and a lid connected to the case main body and receives a management board on which a memory storing data including fiscal information and a management board-side connector are mounted. A control board receiving case includes a case main body and a lid connected to the case main body and receives a control board on which a controller and a control board-side connector connected to the management board-side connector are mounted. The management board receiving case and the control board receiving case are configured such that one box-like body that receives at least the management board is formed while the management board-side connector and the control board-side connector are connected to each other by engaging the management board receiving case with the control board receiving case through engagement members provided in the cases.

  • Publication number: 20110154077
    Abstract: An electronic apparatus is provided. A management hoard includes: a control section; a real-time clock that outputs data indicating current date and time to the control section; a memory that stores fiscal data including the data indicating the current date and time and fiscal information under the control of the control section; and a power source that supplies power to the real-time clock through a power supply path. A housing box includes a box main body and a cover. The housing box that houses the management board. When the cover is in a closed state, the power supply path is formed and the power is supplied to the real-time clock. When the cover is placed in an open state, the power supply path is shut off and the power supplied to the real-time clock is shut off.

  • Patent number: RE42474
    Abstract: An input image signal is coded by an encoder to be outputted as a basic code string, and the basic code string is delayed by a code-string delay circuit for a predetermined period of time to be outputted as an additional code string. The basic code string is synthesized with the additional code string by a code-string synthesizer to be outputted as an output code string. Thus, there is provided an image data coding system which can quickly restore data even if the data is lost due to error and in which the increased code amount is less than the cycle refresh and the error correction.
