  • Patent number: 7175753
    Abstract: A process and a device are provided for monitoring the hydrogen concentration in a gas with at least one device, which comprises an electrochemical gas sensor and a bipotentiostat, e.g., for use in internal combustion engines with hydrogen, in fuel cells and in the petrochemical industry. The electrochemical gas sensor used has two working electrodes (3) and (4), with which the hydrogen and oxygen concentrations are determined in the gas in different steps due to the application of a voltage by a bipotentiostat (5-18). In an additional, optional step, a voltage in the range of ?1,100 mV to ?800 mV is applied to a working electrode (4), so that hydrogen is formed at the working electrode (4) and the functional surface of the working electrode (4) as well as the sensitivity of the working electrode (3) to hydrogen can be checked.

  • Patent number: 7172116
    Abstract: Dispensing more than one card or card like good is prevented to prevent issuing a duplicate with an automatic dispensing machine of card or card like good having a table which supports the piled up card or card like good. A sucking device is located over the table and pulls the card or card like good. A transporting device transports the card or card like good which is pulled by the sucking device. A moving device drives to change the distance between the table and the sucking device. A duplicate detecting device is located at a card transporting passageway which is located downstream the transporting device. A vibrator imparts a vibration to the card or card like good on the table. A separating device acts when the duplicate detecting device detects the duplicate of the goods.

  • Patent number: 7165490
    Abstract: A press forming method is disclosed, wherein press forming can be effected at high speed while maintaining the horizontal state of a slide plate in press-forming a work-piece by a press machine. A press machine is used in which the slide plate is pressed by a plurality of drive sources using servo-motors for driving. The speed of one of the plurality of drive sources is set to a target speed for production forming for the drive source, and by using a function that shows a delay in terms of a speed of the drive source and a load thereon and also using a load separately found, the respective speeds of the drive sources are found so as to eliminate the delay between the drive sources. Trial forming is repeated on the basis of the thus-found speed to derive conditions that enable press-forming at high speed while maintaining the horizontal state of the slide plate.
