Abstract: For a friction plate, when a friction clutch is in a disengagement state, a lubricating oil flowing from an outer circumferential oil groove into an inner circumferential side and rides onto a first segment of a first friction material set. For the friction plate, the lubricating oil flowing from an inner circumferential oil groove into the outer circumferential side rides onto a third segment of a second friction material set.

Abstract: A friction plate in which a powdery or staple fiber-shaped friction material is bonded to a metal core plate is produced by electrostatically spraying a particulate mixture containing the friction material and a thermosetting resin onto the core plate so that the particulate mixture is temporarily attached to the core plate by electrostatic attraction, and then heating the core plate with the mixture attached thereto in order to cure the resin.

Abstract: Problem—To provide a friction plate with reduced drag torque.Solution—The friction plate is formed with oil grooves having the sectorial shapes spreading toward the inner circumference and the perimeter. The adjacent edges of the friction material segments are provided with the perimeter side vertex and the inner circumference side vertex respectively. The sectorial oil groove opening toward the perimeter side from the inner circumferential side vertexes can discharge a lube oil to the perimeter side efficiently by a centrifugal force. Also, owing to the sectorial oil groove opening toward the inner circumference side from the perimeter side vertexes, a lube oil can be made to run aground onto the friction material segments due to a centrifugal force, thus, reducing the drag torque markedly compared with the conventional plates.

Abstract: There is provided a method of producing hydrogen gas serving as fuel for a portable fuel cell, whereby hydrogen gas can be provided easily, safely, and at a low cost. To that end, the method of producing hydrogen gas comprises the steps of causing friction and mechanical fracture accompanying the friction to occur to a metallic material under water and increasing thereby chemical reactivity of atoms of the metallic material, in close proximity of the surface thereof; wherein water molecules are decomposed by accelerating corrosion reaction of water with the metallic material. Further, for the metallic material, an aluminum or aluminum alloy material is used as industrial waste including refuse and cutting chips (curls) of an industrial aluminum material. Meanwhile, pure water not substantially containing ionic impurities and organic molecules is used for the water.
