  • Patent number: 7576494
    Abstract: The present invention applies to provide a lighting method of a high pressure discharge lamp dedicated particularly for image equipments in which re-lighting when turning ON the switch again immediately after the switch OFF is instantaneously performed even in the high pressure discharge lamp. In the transition state of transitioning from the lighted state to light off, the lamp power to be supplied to the electrodes (3), (4) is reduced to an extent an arc discharge does not disappear and maintained for a while, and thereafter, transitioned to the glow discharge after lowering the lamp temperature to a temperature capable of maintaining the glow discharge and maintaining the glow discharge for a while, and the current supply to the electrodes (3), (4) is cut at the point the lamp temperature becomes lower than or equal to the temperature at which re-lighting is possible.

  • Patent number: 7516242
    Abstract: An integrated information communication system capable of improving information security is provided, in which an IP packet is detected which is sent from an external area toward either an operation management server or a relay apparatus, the detected IP packet is not entered inside the integrated information communication system in order to reduce such a chance that the operation management server and the relay apparatus are unfairly attacked. Also, such an IP packet is detected and discarded, which violates an address application rule established so as to keep secret of a communication company network. An address which is applied to either an operation management server or a relay apparatus employed in the integrated information communication system is sectioned, or classified as an “address which is not opened outside network” with respect to an external area of the communication system. A packet filter is installed in an address control apparatus.

  • Publication number: 20080042538
    Abstract: This invention makes it possible to use a concave reflection mirror using metal in at least a concave reflective portion thereof for discharge lamps. The concave reflection mirror is characterized by including: a metallic concave reflective portion; and a neck portion for receiving therein a high voltage side seal portion of a high-pressure discharge lamp to be continuously applied with a d.c. voltage of 1000 V to 4000 V during an ignition phase, the neck portion protruding rearward from a central portion of the metallic concave reflective portion and being formed partially of an insulating member or entirely of an insulating material. The concave reflection mirror can have a concave reflective surface with improved curved surface precision thereby making it possible to reduce variations in brightness, use a multi-layered deposited film having a low heat resistance, and reduce the required cost considerably.
