  • Internal combustion engine and power generation system
    Patent number: 11536206
    Abstract: An internal combustion engine includes an internal combustion engine main body including a plurality of cylinders, a knock sensor provided on each of the plurality of cylinders, a control board including an amplification circuit, and a plurality of cables differing in length and each connecting the knock sensor and the control board. The amplification circuit includes, for each of the plurality of cables, a first charge amplifier connected to a first output terminal of the knock sensor via one of the plurality of cables, a second charge amplifier connected to a second output terminal of the knock sensor via one of the plurality of cables, and a differential amplifier configured to take an output of the first charge amplifier and an output of the second charge amplifier as input.
    Type: Grant
    Filed: August 2, 2019
    Date of Patent: December 27, 2022
    Assignee: MITSUBISHI HEAVY INDUSTRIES ENGINE & TURBOCHARGER, LTD.
    Inventors: Michio Onozuka, Daisuke Komori, Yosuke Kitamura, Sakiya Watanabe, Ko Takayanagi

  • Nitride semiconductor light emitting device and method of fabricating the same
    Patent number: 9666753
    Abstract: A nitride semiconductor light emitting device includes a substrate as a base and an n-type semiconductor layer grown on a surface side of the substrate. Antimony (Sb) is added to the n-type semiconductor layer so that a molar fraction is not less than 0.1% and is less than 1%. A concentration of an n-type impurity in the n-type semiconductor layer is lower than an electron concentration.
