  • Patent number: 8639959
    Abstract: A first switch is arranged between a judgment unit and a signal line. The first switch is turned on during a period in which the judgment unit judges a device, after which the first switch is turned off. A second switch is turned off during a period in which the judgment unit judges the device, after which the second switch is turned on. The signal line connects a communication interface port, which allows various different kinds of devices to be connected, and a communication terminal of a processor configured to perform data communication with the device. The judgment unit monitors the electrical state of the signal line, and judges the device connected to the port.

  • Publication number: 20140020764
    Abstract: A method comprises transporting a first stream of a carrier gas to a delivery device that contains a liquid precursor compound. The method further comprises transporting a second stream of the carrier gas to a point downstream of the delivery device. The first stream after emanating from the delivery device and the second stream are combined to form a third stream, such that the dew point of the vapor of the liquid precursor compound in the third stream is lower than the temperature of the plumbing that transports the vapor to a CVD reactor or a plurality of CVD reactors. The flow direction of the first stream, the flow direction of the second stream and the flow direction of the third stream are unidirectional and are not opposed to each other.
