The invention provides a self-cleaning device of a full-automatic washing machine, which is used for solving the problem of secondary contamination on clothes caused by clustered dirt in the interlayer between the water storage tank and the dehydration tank, and in the interlayer between the dehydration tank bottom and the impeller bottom of the washing machine. The interlayer between the water storage tank and the dehydration tank is provided with a plurality of clean balls 3, and a plurality of clean balls 5 are arranged between the dehydration tank bottom and the impeller bottom. When the washing machine washes or rinses, the clean balls perform friction with the water storage tank wall, the dehydration tank wall, the impeller bottom and the dehydration tank bottom to clean the dirt inthe positions, and simultaneously the clean balls are self cleaned through mutual collision and friction. By adopting the way in which the water storage tank rotates along with the dehydration tank when dehydrating and the storage tank wall or bottom is provided with a groove or a piston cylinder (to lead the clean balls to drop into the groove or the piston cylinder when dehydrating), the clean balls do not generate friction with the dehydration tank, thus prolonging the service life of the clean balls and saving energy; and the adoption of the way in which the water storage tank rotates along with the dehydration tank when dehydrating can decrease the width of the interlayer between the water storage tank and the dehydration tank to save water.

An optically clear encapsulant for optoelectronic packages exhibits a suitably high viscosity both to replace a silicon nitride passivation layer required on a VCSEL die and to fill a gap between the die and an optical coupler, preventing light signal degradation. The encapsulant exhibits optical transparency to light having a wavelength of about 850 nanometers (nm) with substantially no Mie scattering since particulate fillers are not required to modulate viscosity in the encapsulant. Also, the encapsulant further seals wire bonds between the die and a cable header to prevent abrasive wear. The gap-filling encapsulant is particularly suitable for use with vertical cavity surface emitting laser (VCSEL) technology. The encapsulant includes prior to curing, a difunctional acrylate epoxy resin exhibiting pseudoplastic flow and a viscosity of greater than about 0.7x106 centipoise. Accordingly, a method of manufacturing an optical subassembly may eliminate a separate passivation step and instead fill the gap between the die and optical coupler with an optically clear encapsulant.

A flexible heat pipe is disclosed for use with evaporator and condenser elements for removing heat from electronic components. The flexible heat pipe comprises a bellows member fixed at one end to a condenser member and at an opposite end to an evaporator member. A cable artery is disposed within the bellows and is fixed at one end to the evaporator, and slidingly engages the condenser at the opposite end. The bellows acts as a flexible vapor envelope, and the cable artery acts as a flexible wick for directing condensed working fluid from the condenser back to the evaporator. The sliding connection between the cable artery and the condenser allows relative axial movement, and the inherent flexibility of the cable artery allows relative lateral movement. Thus, the condenser and evaporator can move in all directions with respect to each other, which can provide desired vibration isolation of the two components.
