  • Patent number: 9909578
    Abstract: There is provided an integrated electric compressor that can be made small in size while reducing radio noise effectively. In an inverter of the electric compressor, a snubber circuit 21 comprising a resistor R and a capacitor C is provided between input/output terminals 20 of a power source and a switching element 18. The snubber circuit 21 is formed by surface mounting a resistive element constituting the resistor R and a capacitor element constituting the capacitor C on a power board 16. A leakage current from a motor 19 is thus restrained and radio noise is reduced. The resistive element and the capacitor element constituting the snubber circuit 21 are preferably surface mounted on the power board 16 on the side opposite to the side on which a control circuit board is arranged.

  • Patent number: 9803148
    Abstract: In a hydrocracking process, the product from the first stage reactor passes through a steam stripper to remove hydrogen, H2S, NH3, light gases (C1-C4), naphtha and diesel products. The stripper bottoms are separated from hydrogen, H2S, NH3, light gases (C1-C4), naphtha, and diesel products and treated in a second stage reactor. The effluent stream from the second stage reactor, along with the stream of separated hydrogen, H2S, NH3, light gases (C1-C4), naphtha, and diesel products, are passed to a separation stage for separating petroleum fractions. Preferably, the effluent stream from the first stage reactor is passed through a steam generator prior to the steam stripping step. In an alternate embodiment, the effluent stream from the first stage reactor is passed through a vapor/liquid separator stripper vessel prior to the steam stripping step.

  • Publication number: 20170292471
    Abstract: A lower water jacket of a cylinder head includes a lower/upper exhaust collecting portion cooling portion configured between a lower exhaust collecting portion and an upper exhaust collecting portion by bypassing a lower exhaust collecting portion cooling portion. Besides, cooling water flowing through the lower/upper exhaust collecting portion cooling portion is merely cooling water of the lower water jacket, and cooling water of an upper water jacket does not flow through the lower/upper exhaust collecting portion cooling portion. Therefore, in the lower/upper exhaust collecting portion cooling portion, interference may not occur in cooling water of the two water jackets to restrain smooth flowing, and cooling effects of an area sandwiched by the lower exhaust collecting portion and the upper exhaust collecting portion are further improved.
