Abstract: A method is disclosed for precision control of pole tip recession of magnetic recording heads. This is achieved by first constructing the head so that the thermal expansion coefficient of the recording head is different from the thermal expansion coefficient of the overcoat. Then the recording head is heated during the lapping process of the slider and recording head. The average and distribution of the recession between the overcoat and the recording head pole tips are improved.

Abstract: Phosphonic acid agents are synthesized and characterized which are potent inhibitors of angiogenesis, tumorigenesis and metalloproteinase activity. Their method of use for the inhibition of angiogenesis and metalloproteinase and the treatment of tumors is also shown.

Abstract: A vibrating device for vibrating liquid provided in vessels comprises a vibrating table (32) whereon the vessels are mountable. The vibrating table (32) is supported eccentrically on a flywheel (10). Due to the eccentric support of the vibrating table (32) on the flywheel (10), high centrifugal forces occur during the operation of the vibrating device, deteriorating the stability of the vibrating device. According to the invention, an adjustable counterbalance weight (76) is connected to the flywheel (10) for balancing the centrifugal forces occurring. For adjustment purposes, the counterbalance weight (76) can be shifted along a guiding device (78). The guiding device (78) comprises a guiding spindle (80) whereon a threaded adjusting nut (87) is provided. By rotating the adjusting nut (87) by means of an adjusting wrench (88), the counterbalance weight (76) can be shifted in the guiding device (78) radially to the flywheel (10).
