  • Inhibitor of Insulin Multimer Formation
    Publication number: 20090264338
    Abstract: An insulin preparation having an ultra-rapid onset of action is provided by adding a substance that interacts with the insulin dimer formation surface or the hexamer formation surface to an insulin solution. The substance exerts its effect by inhibiting insulin dimer formation and/or hexamer formation.

  • MUTANT PROTEIN HAVING THE PEPTIDE-SYNTHESIZING ACTIVITY
    Publication number: 20070292916
    Abstract: The present invention aims at providing an excellent peptide-synthesizing protein and a method for efficiently producing a peptide. The peptide is synthesized by reacting an amine component and a carboxy component in the presence of at least one of proteins shown in the following (I) and (II). (I) The mutant protein having an amino acid sequence comprising one or more mutations from any of the mutations 1 to 68, and the mutations 239 to 290 and 324 to 377 in an amino acid sequence of SEQ ID NO:2.

  • Device for measuring concentration/flow rate of a mixture drawn into an internal combustion engine and air-fuel ratio control system of the engine incorporating the device
    Patent number: 5188085
    Abstract: A device for measuring a flow rate of a mixture of evaporative fuel and air supplied to an internal combustion engine comprises a plurality of flowmeters arranged in a purging passage connecting between a canister and an intake passage of the engine for purging the mixture of evaporative fuel and air therethrough into the intake passage. The flowmeters have different output characteristics relative to concentration of the evaporative fuel in the mixture. At least one of the concentration of the evaporative fuel in the mixture and the volumetric flow rate of the mixture are detected based on outputs from the flowmeters. In an air-fuel ratio control system incorporating the above device, the weight per unit time of evaporative fuel supplied to the intake system is calculated from the detected concentration of the evaporative fuel and the detected volumetric flow rate of the mixture.
