Title: Production of unsaturated carboxylic ester
Inventor: KAI HIROAKI
IPC: C07C69/54
Filed: 1996-12-25
Abstract: PROBLEM TO BE SOLVED: To obtain an unsaturated carboxylic east in high yield with reduced formation of by products by reaction of a specific amount of an unsaturated carboxylic acid with a cyclic alcohol in the presence of a catalyst. SOLUTION: An acidic catalyst is used for carrying out the reaction of an unsaturated carboxylic acid with a cyclic alcohol where the molar ratio of the carboxylic acid to the alcohol is kept in the range from 1/1.1. to 1/1.5 at the initial stage and at 1/(8-10) at the latter stage. The unsaturated carboxylic acid is, for example, methacrylic acid, the cyclic alcohol is cyclohexanol and the acidic catalyst is p-toluenesulfonic acid. The molar ratio of the reactants are kept at a constant level to suppress the decomposition of the staring alcohol, thus increasing the selectively of the starting alcohol. The concentration of the aqueous alkali to used for neutralizing the catalyst is kept constant to prevent the recovery loss due to the phase separation whereby the yields of the product and the starting alcohol can be increased.

Title: Cutout anisotropic cylindrical magnet
Inventor: NAKATSUKA SATORU
IPC: H01F7/02
Filed: 1991-12-26
Abstract: PURPOSE:To effectively alleviate change of the magnetic density at the gap of the boundaries of stator magnetic field and thereby prevent generation of cogging by forming cutout portions to non-effectuating surface regions including a part of the effectuating surface and gradually reducing the area of the cutout part at the effectuating surface at least in its circumferential direction. CONSTITUTION:While a synthetic resin magnet material supplied into a cylindrical cavity 1 is still in the soft condition, a magnetic field is applied to this magnet material to orient the axes of easy magnetization of magnetic particles in the magnet material along the direction of the line of magnetic force. Thereby, a cylindrical magnet converges both in the sections in the longitudinal direction and in the sections in the lateral direction. Even in this case, the cutout portions in which the areas thereof are gradually reduced in the one circumferential direction are provided within the cavity 1. Accordingly, generation of cogging can be prevented by effectively alleviating change of magnetic flux density at the gap of the boundaries of stator magnetic field and moreover torque can further be improved.
