The invention relates to an unhooking device. The unhooking device comprises a fixed piece and a hook; the hook comprises a first half hook and a second half hook; at least the first half hook is hinged to the fixed piece; the fixed piece is provided with a vertically arranged guide rail which is provided with an adjusting piece; the adjusting piece is connected with the first half hook through afirst connection rod; the two ends of the first connection rod are hinged to the upper end of the first half hook and the adjusting piece correspondingly; when the adjusting piece moves in the vertical direction of the guide rail, the first half hook rotates along a hinging point on the fixed piece and achieves opening and closing of a hoisting hole; and the adjusting piece is fixed to the presetposition of the guide rail through a positioning piece. The unhooking device is simple in structure, small in size and low in cost, the lever principle is fully utilized to achieve carrying of the hook and unhooking unloading, labor is saved, reliability is high, effects are direct, the unhooking effect is good, the instant unhooking opening effect can be achieved, action delaying is avoided, unloading and falling positions of carried articles are accurate, high-speed unhooking releasing can be achieved, and the unhooking device is especially suitable for carried articles with large load and hoisting of goods carried at high speed.

A decoupling device for decoupling a high-frequency noise wave in a digital circuit is formed as a line device including a portion of a semiconductor substrate, an insulator film formed thereon as a gate oxide film, and an interconnect line formed thereon as a gate electrode. The line capacitance between the interconnect line and the semiconductor substrate is 100 pF or above, whereby the decoupling device effectively decouples the electromagnetic noise wave generated by a switching device in a frequency range between 10 and 1000 GHz.
