Title: Inserted drill
Inventor: KUBOTA MASAO
IPC: B23B51/00
Filed: 1985-10-11
Abstract: PURPOSE:To enable a drill, applicable even for a small diameter with good balance of cutting resistance, to be cheaply presented, by using a tip, which lacks an intermediate part of each side of a triangle, and a hexagonal tip which cuts this cutting edge lacked part. CONSTITUTION:Cutting edges are provided on two straight lines OV1, OV2 forming equal angles alpha from a point O on a tool center line OO1, and a center side tip 1, having the cutting edges approaching to the point O, is formed into a shape, lacking intermediate parts 011, 012, 013, by using a triangular tip providing roundness in the top point. While a centerless side tip 2, having no cutting edge approaching to the crossing point O, is formed into a hexagonal shape by removing each top point part 021, 022, 023 so as to provide an edge width not less than the edge width necessary for cutting a part, left as not cut by said lacked parts, to be removed. In this way, cutting resistance of the both tips is balanced. The angle alpha is desired to be 60 deg.. An external diameter can be changed by changing a size of the tip and its angle, but when the external diameter is that or more, additional tips are symmetrically provided in the peripheral side of the both tips.

IPC: G11B7/135
Filed: 1999-08-09
Abstract: PROBLEM TO BE SOLVED: To provide a method for assembling an optical pickup which can restrict the offset of DPD signals. SOLUTION: In assembling an optical pickup, the size and the angle of astigmatism of collimator lenses 16 in the production lot used as a collimator lens 16 for the pickup are measured for sampling, and an average angle from a lens reference position of astigmatism of the lot is obtained.
