Title: Formation for opening in filmlike substance
Inventor: YAMANO TAKESHI
IPC: H01L21/306
Filed: 1980-02-01
Abstract: PURPOSE: To form a desired tapered opening in a filmlike substance on a substrate without carrying out high-temp. treatment by implanting ions into the substance in a desired form to utilize a difference in etching resistance.  
     CONSTITUTION: Insulating film 6 and photoresist film 7 are formed on semiconductor substrate 1. Part of film 7 is removed, film 7 is softened by heat treatment to form tapered opening 8, and predetermined ions are implanted to form tapered ion implanted region 9 corresponding to opening 8 in film 6. Film 6 is then etched using film 6 as a mask to expose part of substrate 1. At this time, since region 9 is easy to etch, it is removed quickly, and tapered opening 10 expanding toward the upper surface of film 6 is formed in film 6. Thus, the disconnection of wire or other trouble at the outer edge of opening 10 is prevented even if a wiring film is formed through opening 10 after removing film 7.

Title: Modification of clay for china
Inventor: SUDO YOSHIMITSU
IPC: C12N1/00
Filed: 1991-02-01
Abstract: PURPOSE:To increase plasticity of clay and to remove iron content by adding specified amts. of nutrients such as starch, protein to a clay slurry. CONSTITUTION:To a clay slurry, one or more kinds of starch, decomposed material of starch, protein, amino acids are added by 0.1-2wt.% to the clay. Thereby, microbes intrinsically present in the clay or naturally mixed from air to the slurry can act in the slurry and rapidly increase in number. In this process, many kinds of materials which are adsorbed or absorbed on the clay grains are produced. Thereby, hydrophilicity of the clay and the holding effect of interlayer water are increased, which improve the plasticity of the clay. Further, the adsorbed material is decomposed with germ to increase the volume in the crystal and produced fine particles. Then after the microbes consume oxygen, aerophobic microbes increases to reduce the iron compd. in the clay and to elude as Fe<+2>. Since the Fe ion changes into iron oxide and iron hydroxide and precipitates when exposed to air, the iron content can be separated from the clay by adding an oxidation preventive.

Abstract: PROBLEM TO BE SOLVED: To estimate the residual life of brazed part between the clip of a stator coil and a copper wire and the insulation layer of stator coil in an electric rotating machine employing a water cooling system. SOLUTION: When the state of a brazed part between the clip 2 of a stator coil and a copper wire 1 and the development of corrosion hole are evaluated in an electric rotating machine employing a water cooling system, the brazed part between the clip 2 of stator coil and the copper wire 1 is sampled and the brazed part thus sampled is cut in the direction of copper wire 1. The length of a part 7 brazed with a brazing material is then measured as the length in the direction of copper wire 1 thus determining the effective seal length at the brazed part. Based on the effective seal length of each cut face, the shortest effective seal length is estimated for all clips 2 of stator coil (of one electric rotating machine) by statistic processing. Finally, the residual life of brazed part subjected to corrosion due to contact with a different metal is estimated based on the shortest effective seal length and a predetermined developing rate of corrosion due to contact with a different metal.
