  • Patent number: 11008999
    Abstract: A wave power generation system includes a wave receiving member, ram cylinder hydraulic pump device, change value sensor, accumulator device, hydraulic motor, power generator, and controller. The member is arranged near a virtual reflection surface that reflects a coming incident wave. The controller sets a torque command used when the generator generates electric power. Based on a differential value of a change value detected by the sensor and changes in accordance with a swing amount of the member, the controller determines whether the member is swinging toward a first or second side in a swing direction. When the controller determines the member is swinging toward the second side by receiving force of a reflected wave reflected by the virtual reflection surface, the controller changes the torque command from the command set when the controller determines the member is swinging toward the first side by receiving force of the incident wave.

  • Publication number: 20210130926
    Abstract: The present invention relates to a method for recovering nickel and cobalt from a nickel, iron, and cobalt-containing raw material. According to the present invention, high concentrations of valuable metals, such as nickel and cobalt, can be recovered from a raw material containing nickel, iron, and cobalt, and especially, the concentrations of nickel and cobalt are low and the concentration of iron is high, and thus when nickel is leached, and relatively large amount of iron is leached, whereas a small amount of nickel is leached. Therefore, the present invention can be more suitably applied in the smelting of nickel ore in which the separation of iron and nickel is difficult.
