IPC: C07C37/74
Filed: 2000-01-27
Abstract: PROBLEM TO BE SOLVED: To provide a process for removing hydroxyacetone from hydroxyacetone-containing phenol so that loss of phenol may be minimized with the minimized energy consumption. SOLUTION: The vapor form of hydroxyacetone-containing phenol that occurs in the decomposition of cumene hydroperoxide by the action of an acid catalyst is treated with a base. In this invention, the steps of distillation and reaction are carried out by introducing a vapor phase taken out of the top of a distillation column into a reactor in which the vapor phase is allowed to react with the base or the reaction is carried out in the distillation column and the hydroxyacetone-containing phenol and the base and fed in combination. In this process, the energy to be used in the removal of hydroxyacetone is more reduced than that in the known process and the loss of phenol is also reduced. Particularly, the process can be applied to a post-treatment of crude phenol occurring in the Hoc phenol synthesis.

Title: Brushless motor
Inventor: SUZUKI MITSUO
IPC: H02K21/22
Filed: 2000-03-02
Abstract: PROBLEM TO BE SOLVED: To reduce eddy currents induced by fluxes leaking from rotor magnets of a brushless motor and suppress the temperature rise of the brushless motor, due to eddy current loss. SOLUTION: Magnetic elements 24 and 25 are placed on open magnetic path sides of rotor magnets 11 of a brushless motor 2. Fluxes leaking from the rotor magnets 11 are drawn toward the magnetic elements 24 and 25, so that fluxes penetrating into other fixed components provided in the neighborhoods of the rotor magnets are reduced. Eddy currents, therefore, are reduced in the other fixed components, in which the penetrations of the fluxes leaking from the rotor magnets 11 can be reduced. Although eddy currents are induced in the magnetic elements 24 and 25, as they are placed on the open magnetic path sides and distances between them and the rotor magnets 11 are large, the eddy currents induced in the magnetic elements 24 and 25 can be reduced.  With this constitution, the eddy currents in the brushless motor 2 as a whole can be reduced, so that the temperature rise of the brushless motor caused by the eddy current loss can be suppressed.
