  • Patent number: 10183670
    Abstract: The drive system from the engine (1) to the drive wheels (7) of a vehicle is equipped with a torque converter (2), which has a lock-up clutch (3), and a variator (4). Said engined car is provided with a lock-up control means for controlling the engagement/disengagement of the lock-up clutch (3) and a gear change mode switch-controlling means (FIG. 8) for performing control to switch between a “continuously variable gear change mode” and a “DSTEP gear change mode.” While traveling, the gear change mode switch-controlling means (FIG. 8) prohibits gear change by the “DSTEP gear change mode” when the detected oil temperature is at or below a lock-up engagement-permitting threshold for permitting engagement of the lock-up clutch (3) and allows gear change by the “DSTEP gear change mode” when the detected oil temperature is higher than the lock-up engagement-permitting threshold.

  • Patent number: 8394935
    Abstract: An object of the present invention is to provide a industrially appropriate method for producing the ?-anomers of ribofuranose derivatives in a highly selective manner at a high yield. The present invention provides a method for producing ribofuranose derivatives wherein ?-anomers is precipitated from among the generated furanose derivatives by controlling the amount of a reaction reagent used and/or using a poor solvent in the acetolysis reactions of 2,3,5-tri-O-acyl-1-O-alkyl-ribofuranose and 2,3-di-O-acyl-1-O-alkyl-5-deoxy-ribofuranose.

  • Patent number: 7659409
    Abstract: The object of the present invention is to provide 3-hydroxy-3-(2-thienyl)propionamides useful as synthesis intermediates of pharmaceutical preparations and the like and a method for obtaining optically active 3-amino-1-(2-thienyl)-1-propanols using the same with high reaction yield, high optical yield and industrially low cost. According to the present invention, 3-amino-1-(2-thienyl)-1-propanols are obtained by carrying out asymmetric reduction of a ?-ketocarbonyl compound having thiophene ring in the presence of a catalyst constituted from a compound of a group VIII or IX metal in the periodic table (e.g., a ruthenium compound) and an asymmetric ligand represented by a specified optically active diamine derivative (e.g., a diphenylethylenediamine derivative), or using a cell, a treated product of said cell or the like of a microorganism, and as occasion demands, carrying out amidation of the ester group and then carrying out reduction of the amido group.

  • Patent number: 6900298
    Abstract: A process for efficiently producing a nucleic acid derivative by condensing a specific nitrogen-containing heterocyclic compound such as a dinitrogen 6-membered heterocyclic compound or a trinitrogen 5-membered heterocyclic compound with a pentose using a less expensive and safe reagent. Namely, a process for producing a nucleic acid derivative by condensing a dinitrogen 6-membered heterocyclic compound or a trinitrogen 5-membered heterocyclic compound with a pentose in the presence of an iron halide.
