  • Publication number: 20210298926
    Abstract: The stent has an expansive force 0.05 N/mm or less per unit length when it has a diameter equal to the lower limit diameter of the target blood vessel and is measured under the following conditions. A radial force testing system manufactured by Blockwise Engineering LLC is used as a tester. The test conditions include a temperature of 37° C.±2° C. in the chamber of the tester; a stent diameter of 0.5 mm for start of test, and a rate of increase of diameter of 0.5 mm/s in the tester. The test method includes radially compressing the stent disposed in the chamber; recording an expansive force while gradually increasing the diameter of the chamber at the rate of increase of diameter; and dividing the expansive force by the effective length of the stent to calculate an expansive force per unit length.

    Abstract: The air discharge device includes a duct defining: a main flow path through which an air flow passes; and a main hole opened in a flat shape to discharge the air flow as a working air flow toward a downstream from the main flow path. A throttle portion is provided in the duct to reduce a flow path height of the main flow path from an upstream of the air flow toward a downstream of the air flow. A plurality of partitions are arranged to divide the main flow path in a major direction into a pair of side flow paths and at least one center flow path. The plurality of partitions are disposed in the duct such that a flow path width of the center flow path is reduced from the upstream of the air flow toward the downstream of the air flow.

  • Patent number: 11127469
    Abstract: A non-volatile semiconductor memory device that achieves downsizing as compared to conventional cases is disclosed. A non-volatile semiconductor memory device has a configuration in which a memory cell is disposed between a programming bit line and a reading bit line. The reading bit line provided between adjacent memory cells is shared by the adjacent memory cells. This configuration of the non-volatile semiconductor memory device, in which the reading bit line is shared by the adjacent memory cells, leads to reduction of the number of reading bit lines as compared to that in a conventional configuration, and further leads to reduction of the area of a control circuit and a sense amplifier circuit connected with the reading bit line, thereby achieving downsizing as compared to conventional cases accordingly.

  • Patent number: 10301974
    Abstract: An activation control apparatus permits activating a steam turbine safely at high speed in response to a power generation plant state. A heat source apparatus heats low-temperature fluid to generate high-temperature fluid, and steam generation equipment generates steam by thermal exchange with the high-temperature fluid. A steam turbine is driven by the steam, and an adjustment apparatus adjusts a plant operation amount. A thermal effect amount prediction calculation device calculates a prediction value for a thermal effect amount for use for activation control of the steam turbine, and a changeover device decides, based on a state value of the power generation plant, the sensitivity of the thermal effect amount to a variation of the plant operation amount and outputs a changeover signal in accordance with the sensitivity. Based on the changeover signal, an adjustment device calculates the plant operation amount so as not to exceed a predetermined limit value.
