Abstract: To provide a front fender device for a motorcycle in which a front fender extending on front and rear sides of a front fork is mounted on the front fork in such a manner as to cover an upper side of the front wheel. The device is intended to increase the degree of freedom in design while minimizing an increase in weight and reducing vibration and noise from the front fender. Garnishes are mounted on each of right and left outer surfaces of a front fender at a plurality of positions spaced in the longitudinal direction of the front fender with elastic members inserted between the front fender and the garnishes.

Abstract: A method of operating a secondary battery including a stack of secondary cells operable, in the presence of electrolytes, in a charge mode charging electrical power from a source of electrical power and in a discharge mode discharging the charge electrical power from the secondary cell. A part of the electrical power from the electrical power source is used intermittently in the charge mode to provide intermittent circulation of the electrolytes through the secondary cell. The secondary cell continues to operate in the charge mode with the electrolytes residual in the secondary cell after each interruption of circulation of the electrolytes. A part of the electrical power charged in the secondary cell is used intermittently in the discharge mode to provide intermittent circulation of the electrolytes through the secondary cell. The secondary cell continues to operate in the discharge mode with the electrolyes residual in the secondary cell after each interruption of circulation of the electrolytes.
