Title: Perovskite-type organic/inorganic lamellar polymer
Inventor: TAKEOKA YUKO
IPC: C08F38/02
Filed: 2001-11-19
Abstract: It is an object of this invention to increase the stability of the quantum well structure of laminar perovskite compounds having excellent optical characteristics and possible applications in light emitting elements.        In this invention, it was discovered that amines having an unsaturated bond can be introduced into the organic layer of organic-inorganic laminar perovskite compounds comprising a metal halide and an organic amine, and the organic layer can be polymerized by applying external energy such as by irradiating with UV light or radiation. In this way, the quantum well structure is stabilized.        This invention is an organic-inorganic laminar perovskite polymer compound produced by cross-linking unsaturated bonds of an organic-inorganic laminar perovskite compound represented by the general formula (RNH3)2MX4 (in the formula, R is a hydrocarbon group having an unsaturated bond, X is a halogen or mixture of same, M is Group IVa metal, Eu, Cd, Cu, Fe, Mn or Pd).      R is represented by CH3(CH2)n C.ident.C-C.ident.CCH2 (n = 2-14).        It is preferred that M is Pb, and X is a bromine atom.

Title: Integrated optical system for endoscopes and the like
Inventor: HOOGLAND JAN
IPC: G02B23/24
Filed: 2001-02-23
Abstract: Optical systems (1-19) for endoscopes and the like are characterized by an integrated design in which the locations of the components and the aberratio n corrections are no longer tied to the optical functions of the objective (1- 6) and the relays (7-19), and in which the relays may depart from symmetry. The  power requirements can thus be shifted from one group to another, thereby reducing the overall power requirement. Moreover, the aberration correction can be shared between the optical groups of the integrated system.

Title: Adjustable electronic duplexer
Inventor: KOUKI AMMAR B
IPC: H04B1/52
Filed: 2002-12-09
Abstract: A duplexer for a communication device having a transmission unit, a reception unit and a shared antenna. The shared antenna transmits a portion of a transmission signal provided by the transmission unit and receiving a reception signal. The duplexer generates a leakage signal from the transmission unit toward the reception unit. The leakage signal being added to the reception signal. The duplexer comprises a first signal path between the transmission unit and the reception unit. The first signal path comprises a filter unit filtering the reception signal. The filtering unit provides a filtered signal to the reception unit. The duplexer further comprises a second signal path between the transmission unit and the reception unit. The second signal path comprises a cancellation unit which receives a sample of the transmission signal and produces a compensation signal. The injection of the compensation signal to the first signal path substantially reduces the leakage signal, thereby producing a substantially leakage-free reception signal.

Inventor: WILGER WILFRED H
IPC: B29C41/06
Filed: 2003-02-20
Abstract: A rotational molding method for forming two separate molded parts each including an undercut portion includes providing a mold formed from two mold parts connected at a mold junction, introducing a particulate plastics material and rotating the mold about two axes while applying heat to the mold so as to cause the plastics material to melt within the hollow interior and adhere to the inside surface.  An annular heat conduction member extends from an outer edge outside the mold through the junction between the two mold parts to an inner edge inside the hollow interior and carries two undercut mold portions for molding respective undercut portions of the two separate molded parts. A band of a heat insulating material such as Teflon is located around the junction between the parts on the inside of the heat conducting member which prevents the adherence of the plastics material at the band so that the mold molds the separate molded parts each separately from the other. The heat conduction member carries heat from the exterior to the undercut mold portions to ensure proper coating thereof by the plastic as it melts.

Inventor: KRUMMRICH PETER
IPC: H01S3/30
Filed: 2001-09-17
Abstract: Different pump signals (S.lambda.1,..., S.lambda.N) are contradirectionally coupled into an optical fibre (LWL) in order to amplify a WDM signal (S.lambda.i) with stimulated Raman scattering. The outputs of the pump lasers (P1, ,PM) with their different wavelengths are distributed in such a way that all of the channels of the WDM signal have a flat curve for the optical signal-to-noise ratio at the transmission fibre end. A filter (F) for adjusting all of the channel levels is also connected to the output of the Raman amplifier so that the level curve of all of the channels is also flat. As a result, all of the channels of a WDM signal have the same signal-to-noise ratio and identical levels at the fibre end.
