Abstract: A lawn mower includes a cutter blade rotatably disposed in a cutter housing, for cutting grass, a discharge fan rotatably disposed in the cutter housing upwardly of the cutter blade, for discharging grass clippings cut off by the cutter blade, a power source disposed outside of the cutter housing, and a speed reducer mechanism disposed outside of the cutter housing upwardly of the discharge fan, for transmitting mechanical power from the power source at a reduced speed to the discharge fan to rotate the discharge fan at a speed lower than the speed at which the cutter blade rotates. The cutter blade comprises a flat member and lies substantially horizontally.

Abstract: An electrostatic recording sheet comprising a support provided thereon a conductive layer and a dielectric layer, in this order, with the dielectrics layer containing polypropylene particles with a specified size distribution and exhibiting excellent moisture resistance and high transparency.

Abstract: A process for producing a photographic light-sensitive material comprising providing a first light-sensitive photographic emulsion layer on one side of a support having a surface resistivity greater than 10.sup.14 .OMEGA. and a thickness of not more than 230.mu. and providing a light-sensitive photographic emulsion layer or a gelatin-containing back layer on the opposite side of the support wherein between the time the first emulsion layer is coated and the time the opposite surface of the support is coated, (i) the opposite surface of the support is prevented from coming into contact with anything except rolls having a diameter larger than about 50 mm, and (ii) the water/gelatin weight ratio in the photographic emulsion layer(s) coated on the first surface of the support prior to coating the second surface is not less than 1. The process is particularly applicable to production of X-ray films.

Abstract: Each of a pair of belts for conveying a photographing film therebetween comprises an insulating layer and at least one electrically conductive layer whose surface resistivity is less than 10.sup.9 ohms.
