    摘要: Disclosed is a method of a gas-phase catalytic oxidation reaction of propylene, isobutylene, or tertiary butanol with molecular oxygen in the presence of a catalyst to produce a corresponding unsaturated aldehyde and a corresponding unsaturated carboxylic acid, in which the catalyst can be used over a long period of time. Concretely, in the presence of the catalyst containing a complex oxide including molybdenum, bismuth and iron as essential components, at least one factor of a reaction pressure and a molar ratio of molecular oxygen to a raw material is controlled to change in such a way that a rate of reaction of the raw material is kept constant in the temperature range of from (TA−15)° C. to TA° C., when a boundary temperature of the activation energy of the catalyst is set to be TA° C.

    摘要: Second transistors working as temperature-monitoring elements are disposed in the vicinity of the respective first transistors (HBT cells) connected in parallel to amplify an RF signal and at positions where their thermal environments are substantially the same. Each of the second transistors is connected between its collector and its base to thereby constitute a diode through which the current rises as the temperature increases. The collectors of the second transistors are connected with a DC power supply through respective first resistors, and their emitters are grounded through respective second resistors. Further, their bases are connected with the bases of the respective first transistors through respective first inductors.
