On the basis of the planar positions of the spreader 15 and the landing surface 31 acquired by the position acquisition devices 23, 24, the control device 25 causes display, which makes it possible to confirm that the spreader 15 and the landing surface 31 are in positional alignment in plan view, to be displayed on the display device 22, superimposed onto images P1 captured by the camera 21.
This supercharger surplus power recovery device comprises an internal combustion engine that is driven by electronic control of a hydraulically-operated operation device, a first supercharger disposed in an exhaust gas path of the internal combustion engine, a hydraulic pump that is coupled to the first supercharger and produces hydraulic pressure by being rotationally driven, an oil path for supplying hydraulic pressure to the operation device from the hydraulic pump, a controller for electronically controlling the operation device, and a control valve for controlling an exhaust gas flow volume sent to a turbine of the first supercharger. The controller controls the degree of opening of the control valve so that when a load factor of the internal combustion engine is a first value or higher, then a hydraulic pressure production amount produced by the hydraulic pump corresponds to a required amount of hydraulic pressure required in order to drive the internal combustion engine.

It is an object of the present invention to prevent temperature decrease in a border portion of each of heating coils and to enable to eliminate an influence given by the change in a load state. In order to attain this object, an induction heating unit according to the present invention is provided with control units respectively corresponding to a plurality of heating units. A phase detector of the control unit obtains a phase difference between an output current (heating coil current) of an inverter detected by a current transformer reference signal outputted by a reference signal generating section, and inputs it to a drive control section. The drive control section adjusts an output timing (phase) of a gate pulse to be given to the inverter so as to make a phase of the heating coil current of the inverter coincide with a phase of the reference signal outputted by the reference signal generating section. A phase control section controls a variable reactor so as to make the phases of an output voltage and the output current (heating coil current) of the inverter coincide with each other, and improves a power factor of the inverter. Each of the other control units also performs the same control operation.
