Title: Partially impregnated polymer-grindstone compound material for grinder and its manufacture
Inventor: MASUDA TSUNEO
IPC: C08J5/14
Filed: 1988-03-07
Abstract: PURPOSE:To prevent the breakage of a non-grinding surface so as to improve the safety of grinding, and enhance the grinding ability of a grinding surface by allowing thermoplastic and thermosetting polymer to penetrate into the inside pores of a grindstone except the vicinity of its grinding surface. CONSTITUTION:Polymer 6 is allowed to penetrate into the inside pores of a porous vitrified grindstone 7 for a grinder except the vicinity of its grinding surface 1. Thus, the grinding surface 1 is not impregnated with the polymer 6, so that its grinding ability can be kept. And also since the inside pores in a grinding area except the vicinity of the grinding surface 1 are impregnated with the polymer 6, the crack and the breakage of the grindstone 7 can be prevented. Consequently, a clearance between an upper and a lower grindstones can be reduced due to the synergistic effect of those two matters. As a result, the grinding ability can further be improved and the ultrafine grinding of a workpiece can constantly be stabilized.

Title: Processing of surface shape of group 3-5 compound semiconductor
Inventor: KANAYAMA TOSHIHIKO
IPC: C23F4/00
Filed: 1979-05-02
Abstract: PURPOSE:To conduct precision processing of surface of groups III-V compound semiconductor utilizing solving speed of a solution containing ferric compound, by making ion radiation onto the surface. CONSTITUTION:Ar ion 4 of several KeV to several 100KeV is radiated onto a GaAs substrate 1. Damaged section 5 of crystal, excluding a mask 3, is etched in water solution of FeCl3. If HCl is added to this water solution at this time, etching speed becomes able to be controlled in a wide range. By using this method, the damaged section 5 can be selectively solved and etching can be achieved deeply depending on shape of the mask 3. By selecting the etching solvent, it is conversely possible to leave the damaged section 5 unetched selectively. Degree of difference in step to be caused by the etching is determined by chemical composition of the etching solvent and depth of the demaged section. Depth of damage, kind of ion, energy of radiation and amount of radiation are specified by electrically controllable amount, and therefore, this is superior in processing accuracy and reproducibility to the conventional etching solvent which had many instable elements. Further, this method is also effective to AlGaAs compounds.
