Patent CA-2132248-A1 (CA)
Inventor: LIN YING-WEI
IPC: H04N1/387
Filed: 1994-09-16
Abstract: A method of arbitrary image resolution conversion takes an original print ready image at a first resolution and orientation and simulates printing of that image by creating a representation of a page at a particular resolution and orientation using a suitable spot model for the reconstruction function. The image is then filtered with a low pass filter and sampled with an aperture that corresponds to the desired output. The image data, which may be definable at several bits per pixel, is then made print-ready by reducing the number of bits defining each pixel to a valid output state. The reduction step is accomplished through error diffusion methods that maintain the local area gray density level. The filtering step reduces moire in the converted image.

Title: Recording and/or reproducing apparatus for a cartridge accommodating a recording medium and an eject mechanism thereof
Inventor: KURITA KAZUHITO
IPC: G11B17/04
Filed: 1994-09-20
Abstract: An eject mechanism of a recording and/or reproducing apparatus using a cartridge accommodating a recording medium, such as a disc cartridge includes a cartridge holder, an eject lever and a lock mechanism. The cartridge holder is attached to a base member so as to become rotatable between a first position and a second position lower than the first position. The cartridge holder loads thereunto the cartridge and holds the inserted cartridge. The eject lever is attached to the cartridge holder so that it can be freely moved. The eject lever is engaged with the cartridge inserted into the cartridge holder and moved in unison with the inserted cartridge. The lock mechanism restricts the eject lever from moving in a disc cartridge eject direction under the condition that insertion of the cartridge into the cartridge holder is finished and releases a restricted movement of the eject lever in the disc cartridge eject direction when the cartridge holder is rotated from the second position to the first position.

Title: A method and a device for correlating two or more optical pulse signals
Inventor: THOGERSEN JAN
IPC: G02F2/00
Filed: 1993-06-15
Abstract: The object of the invention is to provide a method which makes it possible to determine the correlation between two optical signals, which makes it possible to correlate two optical signals, without using a crystal element which is associated with a plurality of drawbacks, because the components are quite expensive. It has been found possible to replace a frequency doubling crystal by an active, optical wave guide, e.g. in the form of an active, optical fibre, said wave guide transmitting fluorescence which is intensity-related to the arrived signal. When this fluorescence is detected in spectral bands, e.g. in the blue region of the visible light, an image of the strength of the arriving signal may be formed. Current distance delaying of the two correlated signals makes it possible to produce an image of the correlation between the signals.

Title: Method of increasing egg production in avian species by active immunization against vasoactive intestinal peptide
Inventor: HALAWANI MOHAMED E
IPC: A61K39/00
Filed: 1993-09-22
Abstract: The present method of increasing egg production in laying turkey hens includes actively immunizing the hens with vasoactive intestinal peptide. The peptide is conjugated to a protein to induce an antibody response in the hens. The resulting antibodies tie up vasoactive intestinal peptide naturally produced in the turkey. This lack of naturally produced VIP in the turkey in turn prevents the secretion of the hormone prolactin from the pituitary gland of the hens to eliminate the onset of broody behavior. The hens are immunized prior to the laying season and subsequently boosted with immunizations approximately once per month during the laying season.

Title: Multiplex addressing of ferro-electric liquid crystal displays
Inventor: GRAHAM ALISTAIR
IPC: G02F1/133
Filed: 1994-01-26
Abstract: The invention provides a ferro-electric liquid crystal display (FLCDs) with reduced voltages requirements for driver circuits. This enables standard drivers circuits designed to rms address twisted nematic type of displays, to be used for FLCDs. Displays are formed by cells containing smectic liquid crystal material. The cell walls are surface treated and carry e.g. row and column electrodes forming an x,y matrix of addressable display elements. The smectic liquid crystal material switches between two states upon application of a dc pulse of appropriate amplitude polarity, and time. Addressing waveforms are strobe waveforms, e.g. two pulses of opposite polarity in successive time slots, applied to each row in turn. Data waveforms are, e.g. dc pulses of alternate polarity with each pulse lasting one time slot ts. Two data waveforms are needed to switch between the two states; one data waveform is the inverse of the other. Typically a strobe waveform pulse may be 50 volts. In the invention a voltage reduction waveform (VRW) is added to both strobe and data waveforms. This has the effect of reducing the maximum amplitude of voltage needed by the driver circuits, whilst leaving the resultant voltage appearing at a display element at the same value as if VRW were not used. With a reduced voltage requirement, driver circuits previously used for relatively low voltage nematic material type of displays can be used to switch smectic materials.

Inventor: SHIH CHI-KAI
IPC: C08G81/00
Filed: 1994-05-20
Abstract: A staged feeding process for preparing a composition by mixing at least a first polymer and a second, dissimilar polymer forms a final composition comprising  a uniform, small-particle of the first polymer in a matrix of the second polymer. Preferably, the first polymer has a melt viscosity greater than the second polymer. The process comprises the steps of feeding the first polymer in a first feed stage and feeding all of the second polymer as a melt in at least two feed stages to mix the first and second polymers. Alternatively the process may comprise feeding the first polymer in a first feed stage and feeding all of the second polymer in at least two feed stages subsequent to the first feed stage. In either case, this mixing initiates a chemical reaction between the first and second polymers.
