  • Patent number: 8164269
    Abstract: One output power characteristic curve for supplying constant power is provided with respect to a raging voltage range of a discharge lamp, and in addition, a plurality of output power characteristic curves W1, W2 and W3 are provided with respect to a lamp voltage before the rating voltage range. There is provided minimum lamp voltage detecting means for detecting a minimum lamp voltage after a high intensity discharge lamp shifts to an arc discharge in an event where lamp power is supplied to a high intensity discharge lamp based on any initially set output power characteristic curve after the high intensity discharge lamp is started. As the minimum lamp voltage detected by the minimum lamp voltage detecting means is larger in a predetermined minimum lamp voltage range, any larger output power characteristic curve is reset from the plurality of output power characteristic curves W1, W2 and W3, and subsequent power control is performed.

  • Patent number: 8015402
    Abstract: A DHCP/authentication server transmits an IP address and authentication information acquired from the IP address to a home gateway. The home gateway creates authentication data from the authentication information and adds the authentication data to an IP packet received from a terminal, and transfers the IP packet to a false-address checking server. The false-address checking server extracts a source IP address and the authentication data from the IP packet, and creates provisional authentication data based on the source IP address. The false-address checking server checks the provisional authentication data against the original authentication data. If these two pieces of the authentication data coincide with each other, the false-address checking server transfers the IP packet to a communication counter part. If the authentication data do not coincide with each other, the false-address checking server discards the IP packet.

    Abstract: An apparatus for operating a gas discharge lamp. The apparatus includes an electronic ballast and a controller. The electronic ballast includes a half bridge configuration, a full bridge configuration, a first network, and a second network. The electronic ballast is controlled by a controller that causes the half bridge configuration to ignite an arc between electrodes of the gas discharge lamp in an igniter function that uses the first network, to switch the electronic ballast from the half bridge configuration to the full bridge configuration after the arc is ignited so that a buck inverter function using the second network sustains the arc between the electrodes of the gas discharge lamp, and to provide a transient operation function to the buck inverter function to produce a spike voltage that is used to re-ignite the arc between the electrodes of the gas discharge lamp when the arc extinguishes.

  • Publication number: 20110129767
    Abstract: A pellicle 10 for lithography includes a pellicle frame 3, a pellicle membrane 1 adhered onto the upper end surface of the pellicle frame 3 and an agglutinant layer 4 formed on the lower surface of the pellicle frame 3 and the agglutinant layer 4 is formed by hardening a curable composition containing a straight chain perfluoro compound having a perfluoro structure in a main chain. The thus constituted pellicle 10 generates only a small amount of a decomposition gas even when it is used for a long time, thereby preventing solid-like foreign materials from separating out on a pattern region of a photomask 5 and can suppress degradation of an the agglutinant agent contained in an agglutinant layer 4 to be used for fixing a photomask 5 to the pellicle frame 3. Further, this pellicle 10 can be easily peeled off from a photomask 5 and replaced with a new one.
