Title: Integrated optical polarization splitter
Inventor: DIEMEER MARTINUS BERNARDUS JOH
IPC: G02B6/12
Filed: 1991-01-28
Granted: 1999-05-15
Abstract: The invention relates to an integrated optical polarisation splitter based on the mode filter principle, in which the asymmetry, necessary therefor, of the waveguides is obtained by using a polable glassy polymer as optical waveguide material, which material is polarisation-sensitive in the poled state and is not, or virtually not polarisation-sensitive in the unpoled state. A Y-shaped optical waveguide pattern 8 of polable glassy polymer comprises a continuous optical waveguide formed by the optical waveguide sections 8.1 (incoming) and 8.2 (outgoing) in which the polymer is in the unpoled state and an outgoing optical waveguide section 8.3 which connects to said optical waveguide at an acute angle and in a tapered fashion and in which the polymer is in the poled state. Since the poled material is also electro-optical, an electric field, for example generated between electrodes 2 and 10, can still correct any small deviations in the asymmetry. Advantages are simple production, with relatively high tolerances, and a short integration length of the component. <IMAGE>

Title: Controlled drug release composition
Inventor: MORITA YASUSHI
IPC: A61K47/30
Filed: 1991-08-30
Granted: 1997-06-14
Abstract: The present invention is concerned with a controlled drug release composition comprising a hardly soluble drug, a water-soluble macromolecular compound and biodegradable macromolecular compound, which composition can be freely tailored to the required solubility and release pattern of the hardly soluble drug through adjustment of the ratio of said ingredients.

Title: Process for preparation of caprolactam
Inventor: LEE KYUL-SOP
IPC: C07D201/02
Filed: 1991-12-12
Granted: 1994-07-21
Abstract: The recovering method of the low purity caprolactam distilled remnants generated in the nylone polymerization process is characterized by adding at most 5 wt.% solidification inhibitor i.e. alkali (earth) metal (barium oxide or calcium oxide) and at least 0.01 wt.% inorganic halogen compound (calcium chloride) to the remnants composed of lactam and oligomer, and depolymerization-reacting the remnants with a superheated vapor and a phosphoric acid as a decomposition catalyst at 270-300 deg.C in the depolymerization reactor.
