    摘要: There is disclosed a process for producing an aromatic hydroxylic compound by acid decomposition of a hydroperoxide having the general formula (I) ##STR1## wherein Ar represents an aromatic hydrocarbon group having a valence of n; and n represents an integer of 1 or 2, in the presence of an acid catalyst, thereby to provide an aromatic hydroxylic compound having the general formula (II)Ar--(OH)n (II)wherein Ar and n are the same as above defined, characterized in that tetrafluoroboric acid, hexafluorosilicic acid or hexafluorophosphoric acid is used as the acid catalyst. According to this process, the aromatic hydroxylic compound is obtained in a high yield while the by-production of hydroxyacetone is effectively suppressed. In paricular, a more effective suppression of by-production of hydroxyacetone and a higher yield of the target compound can be achieved by carrying out the acid decomposition reaction in two stages wherein the first stage of the reaction is carried out in the first reactor at a temperature of 50.degree.-95.degree. C., the resultant reaction mixture is sent to the second reactor, and the second stage of the reaction is then carried out in the second reactor at a temperature of 80.degree.-120.degree. C.

    摘要: An object of the present invention is to achieve reductions in size and costs of a vehicle-mounted motor driving control board in a configuration which allows the redundancy of a power supply to be ensured. The vehicle-mounted motor driving control board is formed by one printed circuit board on which are formed two inverter driving circuits for driving two inverter circuits for three-phase motors, and a voltage step-up/step-down driving circuit for driving a voltage step-up/step-down circuit for supplying electric power to the inverter circuits. The vehicle-mounted motor driving control board further includes a first power supply circuit for supplying electric power to part of constituent circuits constituting the voltage step-up/step-down driving circuit and the two inverter driving circuits, and a second power supply circuit for supplying electric power to the remainder of the constituent circuits in the voltage step-up/step-down driving circuit and the two inverter driving circuits.
