Abstract: The present invention relates to a metallocene complex with a heteroatom-containing ?-ligand, having a chemical structure represented by formula (I) as below: wherein M is a transition metal element from Group 3, Group 4, Group 5 and Group 6 in the periodic table, including lanthanides and actinides; X, being the same as or different from each other, is selected from hydrogen, halogen, an alkyl group R, an alkoxyl group OR, a mercapto group SR, a carboxyl group OCOR, an amino group NR2, a phosphino group PR2, —OR?O— and OSO2CF3; n is an integer from 1 to 4 and is not zero; the charge number resulted from multiplying n by the charge number of X equals to the charge number of the central metal atom M minus 2; Q is a divalent radical; A is a ?-ligand; and Z is a ?-ligand; the process for producing the same; a catalyst system of the same; and use of the catalyst system.

Abstract: This invention publicly announces a quantificational testing method of semen liquefaction ability. By following the steps of sample preparation, image collection, image quantificational analysis and curve analysis to analyze the quantificational testing of semen liquefaction ability; indirectly indicate the semen liquefaction ability by observing the color depth change in the sperm sampled cover black area; to analyze the quantification of semen liquefaction by observing the level of change in grey level value versus time; thus, to efficiently, subjectively and standardly test the semen liquefaction ability and avoid human errors.

Abstract: A locking includes a locking member, a guiding rod, and a space member. The guiding rod is fixedly connected to the locking member. The mold includes a first mold plate, a second mold plate, a stripper plate, and a top plate. The first mold plate, the second mold plate, the stripper plate, and the top plate are connected in sequence. A receiving hole is defined in the first mold board. A through hole is defined in the second mold board corresponding to the receiving hole. The guiding member movably passes through the through hole. The through hole includes a first retaining portion and a second retaining portion. The space member is sleeved on the locking member. A diameter of the space member is greater than that of the receiving hole and the second retaining portion. The disclosure also supplies a mold.

Abstract: A semiconductor inspection apparatus performs a hybrid inspection process including cell-to-cell inspection, die-to-die inspection and die-to-golden or die-to-database inspection. The apparatus creates a golden image of a reticle complimentary to portions of the reticle that can be inspected by cell-to-cell inspection or die-to-die inspection. Alternatively, the apparatus creates a reduced database complimentary to portions of the reticle that can be inspected by cell-to-cell inspection or die-to-die inspection.

Abstract: The present invention provides an optical amplifier for a wavelength division multiplexed communication system, including a first amplifier stage responsive to changes in gain to cause a wavelength dependent gain tilt in one direction. a second amplifier stage (3) responsive to corresponding changes in gain to cause a wavelength dependent gain tilt in an opposite direction and gain control means (4) for controlling the gain of the first (2) and second (3) amplifier stages to maintain a substantially flat response for the amplifier (1) over time, in which the first amplifier stage (2) is a length of optical transmission fibre providing a Raman amplifier. The present invention provides an optical amplifier which uses dynamic gain tilt adjustment whilst maintaining a constant output level from the amplifier.
