    摘要： An electric injection molding machine capable of maintaining a quality of molded articles and capable of suppressing a variation of weight of articles molded by a mold having a plurality of cavities when transferring molding conditions in a hydraulic injection molding machine as they are to the electric injection molding machine. This electric injection molding machine has an electric injection mechanism for injecting a molding material into a mold by a drive force of an electric motor, an injection control unit and a servo driver for controlling the injection motor so as to follow the injection speed reference, and an reference compensation unit for compensating the injection speed reference based on the characteristics of the hydraulic drive system so that fluctuation characteristics of the injection speed with respect to the injection pressure when controlling the electric injection mechanism approximate the fluctuation characteristics of the injection speed with respect to the injection pressure in the hydraulic injection mechanism performing the injection of the molding material to the mold by the hydraulic drive system.

    摘要： A stationary die is held on the front surface of a stationary platen and a movable die is held on the front surface of a movable platen. A plurality of monitoring sections are set in advance within a moving range of the movable platen and an upper limit of forward thrust of the movable platen is set for each of the monitoring sections. When the forward thrust of the movable platen reaches the upper limit set in one of the monitoring sections during a die closing operation, it is determined that abnormality occurs to stop the movable platen from moving forward. If a die closing mechanism is of a toggle link type, the forward thrust of the movable platen is calculated based on the thrust of a crosshead which drives a toggle link mechanism, the moving speed of the crosshead, and the moving speed of the movable platen.

    摘要： Provided is a wind power generation apparatus to which general purpose inverters are applicable. An inverter in a constant-voltage mode is used. While a wind power generator is generating electricity, switching circuits are turned on and off at a controlled duty cycles to intermittently short-circuit an armature winding, boosting the voltage and controlling the rotational speed of a windmill rotating blade, with the result that the voltage applied to the inverter is made constant. At the activation, in order to prevent an excessive voltage from being generated while an inverter is changing from the stand-by state to the activated state, ON/OFF control of a switching circuit is performed to switch between the output voltage of a rectifier and the voltage generated at a resistor, with the result that the voltage is controlled and maintained at an appropriate value.
