摘要： A grinding method includes a grit sticking step and a grinding step. In the grit sticking step, grit particles are stuck in a first tool by contacting the first tool with a second tool which is harder than the first tool, rotating the first tool and the second tool, and feeding the grit to the contacting surface between the first tool and the second tool. In the grinding step, the workpiece is ground by contacting the first tool with the workpiece and rotating the first tool or the workpiece.

摘要： This invention aims to provide a method of lapping a bevel gear effectively by placing a gear-shaped tool whose axis has the same relation with the axis of the bevel gear as those of hypoid gears. In a double mode, gear-shaped tools are placed whose axes lie in a position offset with respect to the axes of the first gear and the second gear and have the same relation as those of hypoid gears. The first gear is engaged with one gear-shaped tool and the second gear is engaged with the other gear-shaped tool, while lapping liquid is supplied to engaging portions, thereby lapping engaging surfaces of toothed portions of the first gear and the second gear.

摘要： The present invention relates to a method for dressing a hone of a honing wheel which is used for honing a gear to be finished. A dressing tool is brought into contact with the honing wheel under a predetermined constant contact pressure and during the reciprocal feed of the dressing tool. The amount of the contact pressure is maintained constant so as to gradually increase the in-feed of the honing wheel. This is useful in decreasing the number of transverse feeds of the dressing tool.

摘要： An optical pickup head is provided with a light source, a diffracting means for creating a plurality of diffracted beams, a converging means for focusing the diffracted beams onto an optical storage medium, a beam branching means for branching the plurality of beams reflected by the optical storage medium, and an optical detecting means for outputting a signal corresponding to the amount of light of the received beams. The optical detecting means has main beam light receiving portions and sub-beam light receiving portions. The amount of light of the first or higher order diffracted beams when they are substantially focused on and reflected by a focus plane of the plurality of information recording planes is equal to or greater than the amount of light of the zero order diffracted beam when it is reflected without focusing by a non-focus plane other then the focus plane of the plurality of information recording planes. The invention provides an optical pickup head where offset is not generated in the TE signals even during tracking with the objective lens when a two-layered disk is used.
