Disclosed are N-substituted benzenesulfonamides for use in treating or preventing cognitive disorders, such as Alzheimer’s Disease. The engine temperature data value is sent to an engine state display device installed in a watercraft by a LAN. When pore radii giving the one peak and the two peaks are respectively regarded as R1 and R2, R3 where R2 is smaller than R3, R1 is 8 to 11 nm, R2 is 5 nm or more, R2 is smaller than R1, a difference between R1 and R2 is 2 nm or more, R3 is not less than R1, a difference between R3 and R1 is 3 nm or less. As the first conductor pattern and the second conductor pattern carry out inductive operation and the third conductor pattern is capacitive-coupled with these conductor patterns, resonance is made in a band lower than a frequency band prescribed by the length of the lines. A conductor connects the transistor in series with the LED. In one embodiment a single focussingcollimating lens is provided substantially at a focal plane of the element having optical power.
