Abstract: A wheel-axle generator equipped with a rotor configured to rotate with rotation of a wheel and a stator arranged around the rotor. The rotor is fixed to a concave portion that opens toward a vehicle outside of a tire wheel of a wheel. An arm member that has one end attached to a wheel-axle housing or a steering knuckle), that extends so as to stride over a wheel, and that, on a side of an outer surface of the wheel, further extends parallel to the outer surface of the wheel up to a central portion of the wheel. The stator is annularly arranged so as to surround the rotor and is provided on the other end side of the arm member. This arrangement provides space for accommodating a generator without shortening a wheel axle etc. and attaching the generator easily.

Abstract: A toughened glass sheet for use as a windowpane of an automotive vehicle. The toughened glass sheet has a thickness ranging from 2.5 mm to 3.1 mm and has a first characteristic that a number of fragments is not less than 40 within an area of 50 mm.times.50 mm in a fragmentation test in which an impact is applied to a predetermined position of the glass sheet with a hammer or a punch, and a second characteristic that a specified height is not less than 2 m in an impact resistance test in which the specified height is a value at which the glass sheet is broken upon dropping a steel ball having a weight of 227 g.

Abstract: An oral composition which prevents periodontal disease such as gingivitis, periodontitis and alveolar pyorrhoea through the prevention of the colonization of Bacteroides gingivalis comprises an antibody obtained by immunizing a mammal with an antigen selected from Bacteroides gingivalis, its pilus and capsule fractions.
