摘要： PROBLEM TO BE SOLVED: To prevent the ply separation or the reduction in the ply adhesion in a cutting process by cutting a laminated molding with a cutting blade with its one principal plane being pressed and, after drawing up the cutting blade, canceling the pressing. SOLUTION: After a laminated molding 1 is positioned and set with accuracy on a base 21, a fluid pressure cylinder is operated to lower a press body 24. In the pressing of the laminated molding by the press body 24, a load is not necessarily applied but it would be just fine to bring the press body 24 into contact with the laminated molding 1. Next, the fluid pressure cylinder is operated to lower a cutting blade base 23 and a cutting blade 22. When the cutting blade 22 reaches the bottom dead point where it can cut the laminated molding 1, the cylinder is operated in the reverse direction to raise the cutting blade base 23 and the cutting blade 22 with the press body 24 being kept at the same position. When the cutting blade base 23 and the cutting blade 22 are raised up to a certain point, the cylinder is operated in the reverse direction to raise the press body 24.

摘要： PURPOSE:To easily make TiO2 particles fine and to extremely reduce the thickness of a formed thin film by using a sol prepd. with titanium isopropoxide which is alkoxide of Ti with isopropanol, absolute ethanol, distilled water and hydrochloric acid. CONSTITUTION:Titanium isopropoxide which is metal alkoxide of Ti with isopropanol as titanium alkoxide is refluxed in a flow of gaseous nitrogen and slowly mixed with absolute ethanol. A mixed soln. of hydrochloric acid and distilled water is further dropped and the titanium isopropoxide is hydrolyzed and refluxed to prepare a TiO2 sol. A substrate is immersed in the sol, pulled up, dried and heat-treated and these stages are repeated to form a thin TiO2 film of a desired thickness. Since superfine TiO2 particles are easily obtd. and the thickness of the thin TiO2 film can be extremely reduced, the size of laminated chip type electronic parts can be reduced and the performance can be improved.
