Abstract: An electrochromic layer consisting of an electrochromic material film and an electrolyte is provided between transparent electrode films of two glass substrates. An ultraviolet radiation stabilizing agent is not added to the electrolyte. A photocatalytic layer and a porous inorganic hydrophilic layer are formed on the front surface side of the front side glass substrate to make the surface of the device hydrophilic.

Since the master cylinder system is provided with the stroke absorber, a relationship between a depression force imposed on a brake pedal and a brake stroke can be fixed. Since the wheel cylinder system is provided with an output hydraulic control valve controlled so as to produce a braking deceleration rate according to the depression force, another relationship between the depression force and braking deceleration rate can also be fixed.

Abstract: An electroencephalogram (EEG) and an electrocardiogram (EKG) signal are detected, and said EEG signal is divided into segments in synchronization with said EKG signal, whereby said segmented EEG signals are averaged. EKG-originating noises yielded as such are subtracted from the EEG signal, whereby an actual EEG signal is derived. The resultant actual EEG signal is divided into segments in synchronization with a stimulation signal, and the segmented actual EEG signals are averaged for enhancing an evoked response signal.
