IPC: C07C209/88
Filed: 1992-09-30
Abstract: PURPOSE:To obtain an optically active 1-phenylethylamine by carrying out the optical resolution of an (RS)-1-phenylethylamine derivative using a resolution agent consisting of a specific optically active substance having extremely high chemical stability and producible from an inexpensive raw material in high yield. CONSTITUTION:An (RS)-1-phenylethylamine derivative of formula II (R<1> is methyl or methoxy) is made to contact with a resolution agent selected from an optically active N-formylphenylglycine and an optically active tartaric acid anilide derivative of formula I (R<2> is Cl or nitro) in a solvent to form a diastereomer salt. A solution containing the diastereomer salt is cooled or concentrated to crystallize the scarcely soluble diastereomer salt. The remaining mother liquor is cooled or concentrated to crystallize the remaining easily soluble diastereomer salt. Since the resolution agent used in the above process has extremely high chemical stability, it can be recovered from the diastereomer salt solution in high yield without causing the racemization of the agent. The process is excellent in yield and optical purity.

Filed: 1989-10-05
Abstract: PURPOSE:To improve control ability by judging a turning limit in accordance with a sideway acceleration ratio which is largely varied around the turning limit so that motive power transmitted to wheels can be cut down or cut off when exceeding the turning limit. CONSTITUTION:A ECU 44 finds artificial sideway acceleration through an operation means 44a in accordance with signals from a speed sensor 46 and a steering angle sensor 52 and a wheel base (L) of a car, so that a sideway acceleration ratio lambda1, which is the ratio to real sideway acceleration indicated by a sideway acceleration sensor 50, is computed and compared with a critical value memorized in a critical value memory means 44b by a comparison means 44c. The sideway acceleration ratio lambda1 is judged to be a turning limit when exceeding a critical value, so that a clutch control means 44d controls a connecting condition of transmission system clutches 10, 18 and cuts down or cuts off motive power to be transmitted to wheels. A tire increases its gripping force and cornering force equivalent to the decrement of this motive power. It is thus possible to improve control ability.

Abstract: PURPOSE:To separate a transfer material always in a satisfactory state by changing the discharge current of an electrostatic separating means according to the image density at the front end of the image to be transferred so that the separating conditions are made correct. CONSTITUTION:A photosensor 10 is disposed at the proper point on the upper stream side of a primary electrostatic charger 2 when viewed in the traveling direction of a photosensitive body 1 and the light reflected from a semi-transparent plate 14 disposed in the optical path for the light reflected from an original is received by the photosensor 10 by which the density at the front end of the original image is detected.
