Patent NO-965149-D0 (NO)
Inventor: CESHKOVSKY LUDWIG
IPC: G11B7/125
Filed: 1996-12-03
Abstract: Control apparatus and method are disclosed for shifting focus on a multilayered optical medium using closed loop servo operation. The outputs of an astigmatic optical pickup are independently modified by a control signal generator according to a predetermined time varying pattern to produce a deceptive error signal that changes the apparent focal offset seen by a servo circuit. While in closed loop mode, the servo tracks the shifting apparent focal plane from a first information layer of the medium toward a second information layer. Thereafter the control signals are removed, and the servo locks focus on the second information region. <IMAGE>

IPC: A61K9/50
Filed: 1998-05-25
Abstract: The invention relates to a process for the production of morphologically uniform microcapsules that contain peptides, proteins or other water-soluble biologically active substances as active ingredients as well as microcapsules that are produced according to this process with a degree of concentration of between 3 to 30% by weight and a diameter<=8 mum.According to the invention, biodegradable polymers are dissolved in a halogen-free solvent or solvent mixture, and the buffered active ingredient solution, which has a pH of between 6.0 to 8.0, is dispersed into this solution. Then, an aqueous solution that contains a surface-active substance (W/O/W-emulsion) is added to this W/O-emulsion, and the solvent is removed.The microcapsules that are produced with this process do not show any tendency toward agglomeration. The encapsulation efficiency of the process is approximately 90 to 95%.
