An output-torque estimation unit obtains a value of a current input to a motor, from a power converter, and calculates an estimated output torque value which is an estimated value of output torque of the motor, from the obtained value of the current. A load estimation unit estimates a load value of a hanging cargo based on the estimated output torque value which is calculated by the output-torque estimation unit, a speed reduction ratio of a speed reducer, an effective radius of a winch drum, and the winding number which is set by the number setting unit.

After a HEMT is formed, side walls are formed on a semiconductor substrate. Next, a sacrificial layer is formed to cover the HEMT. Next, contact holes are formed in the sacrificial layer to expose upper surfaces of source electrodes. Next, a metal interconnect line is formed by patterning a metal film formed on the entire top surface. Next, slits are formed in the metal interconnect line to partially expose an upper surface of the sacrificial layer. After the sacrificial layer is dissolved, the dissolved sacrificial layer is discharged through the slits to the outside. An air space is formed as a result of the removal of the sacrificial layer.

The laser optical system is arranged so that the optical axes of laser beams from the laser oscillators to the linear beam forming member are in substantially the same plane and substantially perpendicular to the substrate. Each laser beam is reflected from a reflecting mirror and applied to the silicon film on the substrate. Since the laser beams are applied to the substrate at the same time, the area irradiated can be increased, while each radiating laser beam maintains a required radiation intensity, resulting in high productivity.
