    摘要: A heat exchanger unit includes first and second plate heat exchangers disposed in series along a refrigerant flow direction. A refrigerant flows from the first plate heat exchanger to the second plate heat exchanger when the heat exchanger unit operates as an evaporator to heat the refrigerant, and the refrigerant flows from the second plate heat exchanger to the first plate heat exchanger when the heat exchanger unit operates as a condenser to cool the refrigerant. The first and second plate heat exchangers have first and second gas-liquid mixing structures to promote gas-liquid mixing of the refrigerant when the heat exchanger unit heats the refrigerant. The first and second gas-liquid mixing structures are configured such that pressure loss becomes larger when the gas-liquid mixing action becomes higher and such that the gas-liquid mixing action of the first gas-liquid mixing structure is higher than the gas-liquid mixing action of the second gas-liquid mixing structure.

    摘要: A control system for an induction motor of the present invention independently commands the torque current component and the exciting current component of a stator current group supplied to the stator of an induction motor so as to feed-back control the amplitude and phase of the stator current group. The torque current component is commanded to control the output torque of the induction motor in correspondence with the output of a steering force sensor for detecting the steering force. According to an electric power steering apparatus using an induction motor controlled by the control system, a permanent magnet is not used for the motor so additional equipment such as a clutch is not required. Consequently, the structure can be simplified and the size of the unit can be reduced. Further, manual steering operation can be performed in the case of failure.

    摘要: A first link member (7), an upper-limit link member (9a), and a lower-limit link member (9b) are rotatably and axially coupled together. When the throttle is to be opened, the throttle valve (5) is electrically controlled by the motor (4) which has been under the control of an output from the accelerator opening sensing device (3), and at the same time, the throttle valve (5) is mechanically controlled by the wire (12) through the link members (7, 9a, 9b) in response to the degree of opening of the accelerator. A high degree of throttle operation such as traction control, idling control, constant speed run, etc. can be executed normally, and when an abnormality arises, the fail-safe function is at work to close the throttle valve (5).

    摘要: A method for operation of a flash smelting furnace comprising a reaction shaft, a settler connected at one end thereof to the lower portion of the reaction shaft and having a slag discharge port and a matte discharge port disposed on the side thereof, an uptake connected to the other end of the settler and at least one concentrate burner disposed to at least one of the top of the reaction shaft and the ceiling of the settler, in which the concentrate burner comprises at least a concentrate shoot, an oxygen blowing tube inserted in the concentrate shoot and an auxiliary fuel burner inserted into the oxygen blowing tube. In this method, the lower end of the oxygen blowing tube is protruded downward to lower than the lower end of the concentrate shoot and an amount of oxygen at least greater than that required for the auxiliary fuel is blown as an industrial oxygen by way of the oxygen blowing tube into the furnace. Oxygen efficiency can be improved remarkably while the rate of dust occurrence can be reduced.

    摘要: A refrigerating device is provided which can improve COP when a required load is 50% of a maximum load or below. When the load required of a common evaporator is 50% or less, a control unit stops a second compressor and controls the volume of a first compressor. Accordingly, it becomes possible to improve COP when the required load is equal to or below 50% as compared to the case of controlling the first and second compressors simultaneously to a low volume.
