Patent CA-2207680-A1 (CA)
Inventor: COLLETTE WAYNE N
IPC: C08L67/02
Filed: 1995-12-11
Abstract: A substantially transparent package or preform made of a polymer composition including an aliphatic polyketone as an oxygen scavenger having formula (a) where n is the number of repeating units and R is hydrogen, an organic side chain, or a silicon side chain. The aliphatic polyketone may be advantageously combined with other thermoplastic polymers to provide the desired injection molding and stretch blow molding characteristics for making substantially amorphous injection molded preforms and substantially transparent biaxially oriented polyester containers. A multilayer container package may be provided having a core layer of the oxygen scavenging composition, and inner and outer layers of polyethylene terephthalate (PET). The container may further include layers of a high-oxygen barrier polymer such as ethylene vinyl alcohol (EVOH).  When filled with a liquid product including water, the water vapor from the product may permeate the inner and core layers to facilitate removal and consumption of entrapped oxygen by the core scavenging layer. The aliphatic polyketone provides a highly reactive oxygen scavenger which is made from low-cost monomers and which remains colorless during processing.

Title: An integrated optic device with active and passive guide zones
Inventor: BROQUIN JEAN-EMMANUEL
IPC: G02B6/122
Filed: 1997-07-23
Abstract: The device integrates on the same glass substrate (1) a passive monomode guide (2b) achieved by ion exchange in the substrate and an active monomode guide with lateral confinement by the substrate formed by an active thin layer (4) deposited on the substrate and covering a zone (2a) in the form of a channel achieved by ion exchange in the substrate. The passive monomode guide (2b) constitutes the extension of the zone (2a) in the form of a channel of the active guide. The thin layer (4) comprises a transition zone enabling adiabatic passage of the light from the passive guide to the active guide and vice-versa. The transition zone can be formed by an edge (5) of the layer (4) cutting the axis (S) of the zone in the form of a channel obliquely or by a zone of variable thickness of the thin layer.

Abstract: A display device or image processor for displaying images while executing pixel density conversion of an original image, such as enlargement, reduction, rotation, and more particularly, a memory having the arithmetic function of high-speed filtering for data interpolation, such as pixel density conversion.  To provide fractional addresses of original images, which do not generally have integer coordinates, a memory (100) comprises a cell (207) for storing data corresponding to an integer address, arithmetic circuits (202 and 203) for executing interpolation on the basis of the integer component and fractional component of an address read out from the memory cell, and a circuit (216) for judging whether or not the given fractional address exists within the range of the address of the data stored in the memory cell. Since interpolation is executed inside an LSI, the operation speed can be four times higher than the conventional speed.
