  • Patent number: 7911789
    Abstract: In the disk array system, in the basic chassis, HDD modules are installed from a front surface in a front part of a backboard, and duplex CTL modules are installed up and down from a rear surface in a rear part, and duplex power source modules containing fans are installed in the left and right sides thereof. By the operation of the fans, in the rear part, the cooling air flows separately into each CTL module and into each power source module, and the cooling air having passed through the area of the duct by a block in the CTL module is drawn by the fans in the power source module through a ventilation hole and is then exhausted outside. The cooling air flow path to the plurality of ICs is divided by the block. The rotation speed of the fans is controlled by using a temperature sensor.

  • Patent number: 7901720
    Abstract: A process for producing a tea extract containing non-polymer catechins, which includes immersing unfermented tea leaves in ethanol or an ethanol-water solution having an ethanol concentration of from 85 to 99.5 vol % to obtain unfermented tea leaves having a percentage catechin residue of at least 80 wt % based on a catechin content of the unfermented tea leaves before the immersion in the ethanol or ethanol-water solution, and then extracting the unfermented tea leaves with warm water or hot water. The highly-efficient extraction of non-polymer catechins makes it possible to obtain a tea extract, which has an improved taste and does not produce sediment when added to beverages.

  • Patent number: 7767076
    Abstract: The reforming of heavy oil with supercritical water or subcritical water is accomplished by mixing together supercritical water, heavy oil, and oxidizing agent, thereby oxidizing vanadium in heavy oil with the oxidizing agent at the time of treatment with supercritical water and separate vanadium oxide. The separated vanadium oxide is removed by the scavenger after treatment with supercritical water. In this way it is possible to solve the long-standing problem with corrosion of turbine blades by vanadium which arises when heavy oil is used as gas turbine fuel.
