Title: Polymer having (meth)acrylate unit, emulsion thereof, processes for their productions, and adhesive compositions containing the emulsion
Inventor: NAKABAYASHI NOBUO
IPC: C08F220/12
Filed: 1993-05-26
Abstract: ABSTRACT          An emulsion of a polymer comprising (a) a recurring unit derived from a (meth)acrylate and (b) a recurring unit derived from a vinyl compound having a group of -SO3R in which R is a hydrogen atom, an alkali metal atom or ammonium ion.

Title: Computer system
Inventor: TAKAHASHI KATSUNORI
IPC: H04N7/04
Filed: 1993-09-29
Abstract: A game computer system for processing sound data and image data in synchronization with each other is disclosed.      An adaptive difference pulse code modulator (ADPCM) is used to produce high quality sound in synchronization with a horizontal synchronization signal, which is also used for controlling the display cycle of image data, for eliminating time gaps between the displayed image and transmitted sound. The game computer system quickly recovers from interruptions during sound reproduction, and resumes from the point of interruption through the use of pre-calculated, or virtual, sound data to maintain continuous transmission of sound. Because the sampling frequency can be decreased from the optimum frequency as required, the computer system performs linear interpolation upon the sound data to ensure high quality sound reproduction at the lower sampling frequencies. By performing a rounding function upon the data, the ADPCM decoder accurately reproduces sound data resulting in high quality sound reproduction at all times.

Title: Gels for Encapsulation of Biological Materials
Inventor: HUBBELL JEFFREY A
IPC: A61K35/12
Filed: 1993-03-01
Abstract: This invention provides novel methods for the formation of biocompatible membranes around biological materials using photopolymerization of water soluble molecules. The membranes can be used as a covering to encapsulate biological materials or biomedical devices, as a "glue" to cause more than one biological substance to adhere together, or as carriers for biologically active species. Several methods for forming these membranes are provided. Each of these methods utilizes a polymerization system containing water-soluble macromers, species, which are at once polymers and macromolecules capable of further polymerization. The macromers are polymerized using a photoinitiator (such as a dye), optionally a cocatalyst, optionally an accelerator, and radiation in the form of visible or long wavelength UV light. The reaction occurs either by suspension polymerization or by interfacial polymerization. The polymer membrane can be formed directly on the surface of the biological material, or it can be formed on material, which is already encapsulated.

Patent CA-2124954-A1 (CA)
Inventor: MICHALSKI BERNHARD
IPC: G01S15/10
Filed: 1993-09-28
Abstract: In order to set a range finding instrument operating according to the echo-sounding principle using sonic or ultrasonic pulses to an optimum transmission frequency, the transmission frequency is altered stepwise within a predetermined frequency range. During each reception spell following on the transmission of a sonic or ultrasonic pulse an amplitude-time-profile of the received signals is formed and integrated. The integration values obtained for the various transmission frequencies are stored, and an optimum transmission frequency is set to that frequency at which the maximum integrated value is obtained. In order to eliminate the effects of background noise on the determination of the optimum transmission frequency a mean noise amplitude of the received signals is determined and subtracted from the amplitude-time-profile of the received signals before integration.
