Patent EP-0657447-A1 (EP)
Inventor: YAMAGUCHI YOSHIAKI
IPC: C07D319/12
Filed: 1994-12-06
Abstract: A method for the purification of lactide is provided which permits lactide of high optical purity or DL-lactide of high purity to be produced from crude lactide by the removal of meso-lactide from the crude lactide. This method for the purification of lactide is characterized by causing a mixture containing L-lactide and/or D-lactide together with meso-lactide to contact with water thereby effecting hydrolysis of meso-lactide. This method can remove meso-lactide from crude lactide and produce DL-lactide and/or optically active lactide of high optical purity in high yield and, in the production of optically active lactide, can eliminate the restrictions otherwise imposed on the formation of meso-lactide.

Abstract: The vibrating unit for fruit trees presented by this invention consists of two sets of two pairs of counterweights 4-8 and 5-9 that rotate in opposite directions in each set. The counterweights 4-8 are driven by a driven half-shaft 14 that incorporates a speed selector 10, while the other half-shaft 13 is motive. The speed selector synchronizes or disynchronizes the counterweights, adding or suppressing them and thus producing or not a vibrating effect in a circular orbit around the tree.

Title: System and method for key distribution using quantum cryptography.
Inventor: TOWNSEND PAUL DAVID
IPC: H04L9/08
Filed: 1993-12-23
Abstract: A method of communication uses quantum cryptography to encode and decode a signal. A key is distributed on a quantum channel, and information subsequently communicated between the transmitter (1) and receiver (2) on a public channel to determine whether the key has been intercepted. A common transmission medium (3) is used for the quantum channel and public channel. A calibration signal is transmitted over the public channel on the common transmission medium to calibrate the system for the subsequent transmission of a key on the quantum channel. The transmission medium may be an optical fibre and the transmitter may switch between a single-photon output and a multiple-photon output to provide the quantum channel and public channel respectively.

Title: Voltage controlled oscillator with efficient process compensation.
Inventor: JELINEK JULES JOSEPH
IPC: H03K3/354
Filed: 1994-01-31
Abstract: A voltage controlled oscillator (VCO) provides an output signal with an output frequency that varies only minimally for any given input control voltage despite variations in the manufacturing process, temperature and supply voltage. The VCO also includes a multistage ring oscillator which includes a plurality of series-connected current-starved inverter stages. The VCO utilizes a first current source to provide a substantially constant current independent of process, temperature and supply voltage and a second current source to provide a variable current that varies in response to process, temperature and supply voltage. Both current sources generate a respective current signal independent of the input signal to the VCO. An attenuator, responsive to the VCO's input voltage signal (typically from a phase-locked loop filter) provides a control current signal to the ring oscillator. The attenuator receives a supply current created by subtracting the second current from the first current, and utilizes a differentiation subcircuit that attenuates the supply current in response to changes in an input voltage to produce a current control signal that sets the current level in the ring oscillator's cells. The frequency of oscillation of the ring oscillator is determined by the control current signal. Additionally, the VCO circuit may include a current mirror for receiving the control current signal from the attenuator and mirroring the control current signal to the ring oscillator.

Abstract: L'invention concerne un procédé et un système de vaporisation par bombardement électronique activé au plasma. Les procédés connus ne permettent pas d'atteindre de très hautes vitesses de revêtement sous une influence intensive de plasma. Le spectre de matériaux susceptibles d'être déposés doit être très large, même dans le cas de couches isolantes. L'efficacité du procédé doit être élevée. Selon l'invention, le matériau à vaporiser contenu dans au moins deux creusets à vaporiser (1; 2) est vaporisé au moyen de faisceaux électroniques (71). Une tension électrique est appliquée aux creusets à vaporiser, de sorte que les zones du creuset dont se dégage la matériau vaporisé servent d'électrodes d'une décharge électrique. Le matériau à vaporiser sert de cathode ou d'anode. Les creusets à vaporiser (1; 2) sont connectés par les résistances ohmiques (R1; R2) avec le potentiel de masse. Ce procédé et ce système sont de préférence utiles pour revêtir par réaction de larges surfaces, ainsi que pour revêtir par réaction des composants, des outils et des feuillards d'acier (substrat 3).

Abstract: An adhesive film for an adhesive bandage in which an adhesive is coated on one surface of a nonwoven fabric, characterized in that a film which is permeable to water vapor and substantially impermeable to water is laminated on the opposite surface of the nonwoven fabric. 
     A backing sheet is formed in such a structure that an elastic nonwoven fabric is laminated with a film having water vapor permeability and water impermeability, whereby sufficient flexibility and excellent water vapor permeability are provided and help to keep skin respiration and not only to prevent skin irritation caused by stickiness with perspiration or the like but also to completely prevent permeation of water, a detergent aqueous solution or the like into a pad portion or an affected part and further to prevent infection of a wound with bacteria. Water impermeability can be further improved by sealing the edge portion of the adhesive bandage via heat-sealing or the like. Further, the use of the laminating film can realize improvement in break strengths and abrasion resistance of the adhesive bandage, and improve handling characteristics in adhering the adhesive bandage to the affected part.
