Abstract: The present invention relates to a method for manufacturing a nickel-metallic hydride electrode. This invention is characterized in that rare earth-nickel-hydrogen-stored alloy powder is molded by plating it with copper without electrolysis, so that mechanical strength, electric conductivity and reaction velocity can be improved by increasing the amount of plating the surface of a molded electrode with copper.

Abstract: A transmission generates the travelling and PTO outputs of a farm tractor. The transmission can easily generate the travelling output of a 15-step forward movement and a 9-step backward movement and the output of a 4-step PTO by fractionalizing the number of speed changing steps. The transmission uses a large number of identically standardized gears and hub sleeves but reduces the number of built-in parts in each part of the transmission, raises the productivity by using a large number of the same parts and controls the equipment efficiently due to easy disassembly for maintenance.
