Title: Locking bolt (nut) and washer
Inventor: TSUJI TOSHIAKI
IPC: F16B39/282
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a locking bolt (nut) and washer adaptable for a portion where troublesomeness occurs in the case of loosening, no need for loosening again, or loosening due to mischief. SOLUTION: Corrugated cutouts are formed on a contact surface between a bolt and a washer. Sliding rotation is thus enabled in a fastening direction, while it is prevented in a loosening direction by the presence of the corrugated cutouts. A projection is formed on the washer which is caught into a main body or the like by fastening the bolt (nut). It is thus possible to obtain a structure allowing no loosening after once fastening by combiringly using the belt and washer.

Title: Production of silica glass
Inventor: HAYASHI FUSAJI
IPC: C03B8/02
Filed: 1987-05-20
Abstract: PURPOSE:To prevent cracking and crazing when silica glass is produced by a sol-gel process, by using an org. solvent contg. formamide during hydrolysis to increase the strength of gel, substituting other org. solvent for the formamide, drying and sintering the gel. CONSTITUTION:When silicon alkoxide such as silicon tetramethoxide is hydrolyzed to produce silica hydrosol, an org. solvent contg. formamide is used as a solvent and produced sol is turned into gel to produce high strength gel. This gel is soaked in a liq. mixture of an org. solvent contg. no formamide, e.g., ethanol with water to substitute the liq. mixture for the formamide in the gel. The gel is then dried and sintered. The occurrence of large stress due to formamide is avoided and silica glass is produced.
