Title: Ion Beam Processing Position Correction Method
Inventor: IWASAKI KOJI
IPC: G03F7/20
Filed: 2001-01-10
Abstract: PURPOSE: To provide a processing method which can finish fine processing with accuracy without taking much time for check of a datum point, in a con verged ion beam processing method for proceeding with processing by ion beams while referring to the reference mark being the datum point on a sample. CONSTITUTION: This method materializes highly accurate converged ion beam processing in a relatively short time, by executing the position correction work at relatively long intervals in the case of processing not requiring accuracy thereby omitting not efficient position correcting work, though this executes the position correction work by check of a reference mark at short intervals thereby performing highly accurate processing in a fine processing requiring accuracy.

Title: Resinoid grinding wheel having core portion made of metallic material
Inventor: ITO KENJI
IPC: B24D5/04
Filed: 2001-02-23
Abstract: PURPOSE: To provide a resinoid grinding wheel for heavy duty grinding capable of minimizing the resulting waste. CONSTITUTION: This resinoid grinding wheel for heavy duty grinding 10 comprises an inside reinforcement part 10a for enhancing the mechanical strength and a grinding part 10b integrally provided on the outside of the reinforcement part 10a in which abrasive grains 12 are mutually bonded through a phenolic resin. The reinforcement part 10a is made of steel having substantially the same thermal expansion coefficient as the grinding part 10b. Since the elastic modulus of the reinforcement part 10a is higher than in the past, the grinding ratio can be improved. Since the production efficiency is consequently improved, and the life of the resinoid cutting grinding wheel 10 is also extended, the generation of spent grinding wheels can be minimized. Further, since the reinforcement part 10a of the spent grinding wheel is made of steel, it can be repeatedly used with less possibility of breakage and deformation. The resulting waste can be thus remarkably minimized.
