Abstract: The present invention provides a oxazole compound represented by Formula (1), or a salt thereof: wherein R1 is an aryl group which may have one or more substituents; R2 is an aryl group or a nitrogen atom-containing heterocyclic group each of which may have one or more substituents; and W is a divalent group represented by —Y1-A1- or —Y2—C(?O)— wherein Y1 is a group such as —C(?O)—, A1 is a group such as a lower alkylene group, and Y2 is a group such as a piperazinediyl group. The oxazole compound has a specific inhibitory action against phosphodiesterase 4.

Abstract: There is provided a vehicle-power-generator control apparatus that can largely raise the gasoline mileage of an internal combustion engine. The vehicle-power-generator control apparatus includes a boost control unit having a function of making a magnetic-field current control unit perform boost-on control or boost-off control, based on a command provided by an ECU through communication and a function of making the magnetic-field current control unit perform boost-on control or boost-off control, based on at least one of a rotation speed of an internal combustion engine and a temperature of a vehicle power generator.

Abstract: The generator control device for vehicle is provided with a boost permission determination circuit capable of controlling the power generation rate, if there is communication between the engine control device and the generator control device for vehicle, the boost permission determination circuit performs the field current control so that the specified power generation rate is achieved by the communication, if there is no communication between the engine control device and the generator control device for vehicle, based on the rotation speed and temperature of the generator for vehicle, the boost permission determination circuit performs the field current control.

Abstract: To provide a generator controller can determine permission of power generation autonomously within a range where startability is not deteriorated, even in the case where the generator controller cannot communicate with the engine controller. A generator controller, in case of communication normal time with engine controller, permits the generation voltage control when the permission command signal is received from the engine controller and the generator rotational speed is higher than a determination value at communication normal time, and prohibits the generation voltage control at other times; in the case of communication failure time, permits the generation voltage control when the generator rotational speed is higher than a determination value at communication failure time, and prohibits the generation voltage control at other times.
