The present invention relates to novel trifluoromethoxyphenyl-substituted tetramic acid derivatives of the formula ,in whichJ, X, Y, A, B, D and G have the meanings given above,to a number of processes for their preparation, and to their use as pesticides andor herbicides. Embodiments monitor errors occurring in each of a plurality of portions of the application while the application is executing. After a predetermined amount of time, the intensity of the status indicators is faded one of two dim levels depending upon whether the lighting load is on or off. The amount of Al in the ion source layer is 30 to 50 atomic percent. If a pair of differential side gears fixed on the respective axles serve as the bevel gears, the restricting mechanism engages one of the bevel gear to the ring gear through a claw clutch or a friction clutch. It is configured such that a signal of a value outside a range of a normal output voltage is outputted from the first output terminal in the case of the failure diagnosis circuit determining abnormality of the failure diagnosis object section, thereby to improve reliability under abnormal condition.
