Abstract: The present disclosure describes an apparatus for processing one or more objects. The apparatus includes a carrier configured to hold the one or more objects, a tank filled with a processing agent and configured to receive the carrier, and a spinning portion configured to contact the one or more objects and to spin the one or more objects to disturb a flow field of the processing agent.

Abstract: A pivot mechanism and an electronic device applying the same are provided. The pivot mechanism includes a pedestal having a bore passing through the pedestal; a shaft inserted into the bore and having at least two leaning surfaces in parallel to an extending direction of the shaft; two bushes coupled to the shaft and fixed in the bore; and a reed set disposed in the bore and arranged between the two bushes. The reed set includes at least one reed, wherein each reed is wedged in the bore and has a hole through which the shaft penetrates. At least one position limiting portion is formed in the periphery of the hole for orienting the shaft. The position limitation portion further extends inwardly to form a slot, by which a cantilever is formed between the slot and the axis hole to lean against the shaft.

Abstract: A hinge includes a housing member, a mounting member, a pivot shaft, which has one end pivotally coupled to the housing member and a second end affixed to the mounting member, and a set of Torque Unit mounted on the pivot shaft and secured to an accommodation through hole in the housing member, each Torque Unit having a center axle hole with two necks for receiving the pivot shaft and lubricating oil, and a plurality of protruding stop portions and peripheral notches alternatively arranged around the periphery of the upper part thereof for positive positioning in the accommodation through hole of the housing member and for enabling the Torque Unit to be twisted without breaking.

Abstract: A hinge includes a housing member, a mounting member, a pivot shaft, which has a first connecting portion pivotally coupled to the housing member and a second connecting portion affixed to the mounting member, and a friction spring washer set mounted on the pivot shaft and secured to the housing member, each friction spring washer having a peripheral deformable portion and a peripheral notch in the peripheral deformable portion for releasing torque produced against the friction spring washers during rotary motion of the pivot shaft with the mounting member relative to the housing member.
