  • Fuel injection pump
    Patent number: 9243597
    Abstract: A fuel injection pump is provided which can be manufactured without an increase in the manufacturing cost and which is configured so that the sealing performance of an electromagnetic spill valve can be maintained with minimum maintenance cost.
    Type: Grant
    Filed: February 22, 2011
    Date of Patent: January 26, 2016
    Assignees: Yanmar Co., Ltd., Woodward, Inc.

  • FUEL INJECTION PUMP
    Publication number: 20150040872
    Abstract: The purpose of the present invention is to provide a fuel injection pump 1 wherein it is possible to easily position the second fuel supply path 21b of a housing 21 with the fuel supply hole 22a functioning as the fuel path of an insert piece 22, and to secure the insert piece 22 such that same does not rotate within the housing 21.

  • Blood vessel state evaluating device, blood vessel state evaluating method, and computer-readable recording medium storing blood vessel state evaluating program
    Patent number: 8628476
    Abstract: A phase line tilt calculating unit (actual measurement) receives phase characteristics Pa(f) and Pb(f) outputted from frequency conversion units, and calculates phase difference characteristics of actual measurement based on a phase difference on each frequency component between the phase characteristics. A phase line tilt calculating unit (model) calculates phase difference characteristics between a transfer function Ga(f) and a transfer function Gb(f) calculated by a transfer function calculating unit, and outputs the calculated phase difference characteristics to a search unit. The search unit fits a variable k and determines a variable kopt (optimum solution) in which a tilt g(k) and a tilt gexp substantially match each other. The variable kopt is an index indicating a degree of arterial sclerosis of a subject.
