Title: Disk device and brushless motor
Inventor: TAJIMA FUMIO
IPC: G11B19/20
Filed: 1991-03-19
Abstract: PURPOSE:To obtain the device of a small size, light weight and thin type having high reliability and high accuracy by using a brushless motor for a spindle motor for directly driving 8 disk. CONSTITUTION:The spindle motor is the brushless motor having a permanent magnet as a rotor and a 3-phase coil for generating a rotating magnetic field as a stator. The rotor 3 consists of the permanent magnet 5 disposed with N poles and S poles circumferentially at a nearly equal pitch and a rotor yoke 6 constituting the magnetic circuit on the rotor side. The rotor 3 is provided with a shape varying in the distance from the center of the rotor to the outside diameter of the stator with an angle. The magnetic pole 4 having the coil 10 positively generates driving torque by the electromagnetic force between the current flowing in the coil 10 and the permanent magnet 5 of the rotor 3. A shorting yoke 9C part having no coil 10 constitutes a part where the torque is not generated. Consequently, the torque density increases.

Title: Preparation of nitrile
Inventor: TAMURA MITSUHISA
IPC: C07C255/57
Filed: 1982-04-02
Abstract: PURPOSE:To prepare a nitrile useful as an intermediate of agricultural chemicals, etc., easily, by heating an aldehyde and an inorganic acid salt of hydroxylamine in the presence of a solvent which forms azeotropic mixture with water, and removing the produced water from the reaction system by azeotropic distillation. CONSTITUTION:An aldehyde of formula RCHO (R is substituted or unsubstituted aryl) is made to react with an inorganic acid salt of hydroxylamine to obtain the corresponding nitrile of formula RCN. The reaction is carried out by heating the reaction mixture in the presence of a solvent (e.g. benzene, toluene, etc.) which forms an azeotropic mixture with water, thereby removing the produced water from the system by azeotropic dehydration. Addition of an amide (e.g. formamide) to the system improves the selectivity of nitrile. The addition of an acid catalyst is not necessary in the above process, and it is supposed that the inorganic acid which is expected to be separated by the production of oxime serves as an acid catalyst. The lowering of the catalytic effect can be prevented, and the equilibrium of the reaction can be shifted toward the nitrile-formation side by the azeotropic dehydration.
