Abstract: A phase frequency detector with two different delays is disclosed herein. The phase detector comprises a first D flip-flop, a second D flip-flop, a first delay unit and a second delay unit. The first D flip-flop receives a reference signal to output an up signal. The second D flip-flop receives a clock signal to output a down signal. The first delay unit delays the received signal with a first delay. The second delay unit delays the received signal with a second delay. When the reference signal synchronizes with the clock signal and the charge pump currents are calibrated, the high-level pulse widths of the up signal and the down signal are determined based on the first delay, and when the reference signal does not synchronize with the clock signal and the charge pump currents are not calibrated, the high-level pulse widths of the up signal and the down signal are determined based on the second delay.

Abstract: The invention provides a multi-functional polymer-entrapped-cell-bead airlift bioreactor for odor or gaseous emission treatment. Especially, it refers to a reactor that mainly treats a low-and-medium gas flow rate and concentration of volatile organic emission or odorous substances. Particularly, it utilizes synthetic material (PAA beads) and microbial entrapment technology as the microbial source and startup mechanism for gaseous emission and odor treatment. Besides, plastic decomposing Thiosphaera pantotropha can be added under certain condition to be triggered to breakdown the synthetic material (PAA beads) to prevent wastes. This will achieve benefits in low cost, high efficiency and zero secondary pollution.

Abstract: A weight adjustable golf club head is provided. The club head has a trough at a lower part of the club head's back and a weight positioned inside the trough. The trough is arranged to follow the curvature of the club head's bottom. The trough has a tapered mouth along the surface of the club head and a base. There is an insertion hole at a position along the trough. The weight could be inserted into the trough through the insertion hole, and then slid along the trough. The weight contains a seat, a bolt, and a loading ring. The seat has a locking rim and the positioning rim which are inside the trough's base and mouth respectively when the weight is slid into the trough. The seat's body and the locking rim have a number of breaks so that the locking rim could be stretched. When the bolt is screwed into or out of the seat, the locking rim would be stretched or retracted, so that the weight could be locked or un-locked in the trough.
