Abstract: PURPOSE:To enable the fall of a load to be prevented with compact constitution by providing a radially extended outward side plate at both ends of a winding drum having a hoisting rope wound thereabout, and braking the side plate with a brake device, when the rotating speed of the drum is detected as equal to or above the predetermined value with a drum speed sensor. CONSTITUTION:A hoisting rope 14 is wound around the barrel 13a of a drum 13 assembled into a rotary shaft 12, and a load W at the end of the rope 14 is elevated or lowered with the rotation of the drum 13. Disc-shaped side plates 13b and 13c are formed at both barrel ends of the drum 13, and a sensor S and a brake device B are laid on the external surface of one side plate 13b. The sensor S detects the rotating speed of the drum 13, and the speed signal thereof is outputted to a control device C.

Abstract: PURPOSE:To provide high quality recrystallization by an extremely simple method by forming an energy absorption film of a laser beam at part of a polycrystalline silicon film deposited on a silicon oxide film, then having part of the laser beam at the center absorbed by the film, and directing a scanning direction in parallel with the film. CONSTITUTION:After a single crystal silicon substrate 11 is thermally oxidized to form a silicon oxide film 12, a polycrystalline silicon film 13 of 0.5mum is formed, a Ge film of approx. 0.02mum is formed on the film 13, and removed except for part of the film 13. An isothermal line in the irradiating surface of an A<+> laser beam 15, i.e., a solid-liquid boundary 16 is low in temperature at the center of the beam 15 on the film 13 and high at the periphery due to the high absorptivity of the beam 15 of a Ge film 14. Accordingly, since the solid-liquid boundary 16' becomes recess with respect to a scanning line, its solidification is directed from the center toward the periphery, the growing nuclei of the crystal growth is disposed only at the center, thereby forming a recrystallized film of high quality without defect.
