An awakening degree detecting device outputs awakening degree information corresponding to an awakening degree of a driver of a vehicle. A stimulus providing device provides the driver with a stimulus including at least one of a vibration stimulus imparting vibration and an apparent motion stimulus giving an illusion of motion presence. A control device outputs, based on the awakening degree information, a first control signal causing the stimulus providing device to provide the stimulus in a case where the awakening degree is less than a first threshold, and to output a second control signal causing the stimulus providing device to provide the stimulus after the first control signal is outputted.

Water-soluble vinyl copolymers with number average molecular weight 500-20000, having two specified repetition units at a specified molar ratio and a specified end group can serve as an effective agent for reducing a drop in the fluidity of hydraulic cement compositions.

Agents for and method of reducing the fluidity drop of hydraulic cement

Cement dispersion agents composed of water-soluble vinyl copolymers obtained by aqueous solution radical polymerization of five specified kinds of monomers at a ratio within a specified range can provide improved fluidity to high-strength hardened concrete and mortar with extremely low water-to-cement ratio.

Cement dispersion agents

Cement dispersion agents containing a graft copolymer composed of four kinds of constituent unit each having a specified structure can provide improved fluidity to cementing compositions, prevent slump loss after the kneading process and reduce the drying shrinkage of hardened concrete produced at the same time.
