Title: Method for treating oxidative reaction mixture of cyclohexane
Inventor: FUJII KAZUHIRO
IPC: C07C45/85
Filed: 1991-07-16
Abstract: PURPOSE:To remove by-products with a small amount of an alkali by subjecting an oxidative reaction mixture containing cyclohexanol and cyclohexanone obtained by oxidation of cyclohexane to saponifying treatment under specific conditions. CONSTITUTION:An oxidative reaction mixture containing cyclohexanol and cyclohexanone is subjected to saponifying treatment in two stages. The aforementioned oxidative reaction mixture is initially mixed with an aqueous solution of an alkaline carbonate and subjected to primary saponifying treatment at 50-95 deg.C and pH 7-12. The resultant mixture is subsequently separated into the oily phase and the aqueous phase and the above-mentioned oily phase is then mixed with an aqueous solution of a caustic alkali and subjected to secondary saponifying treatment at a pH within a higher range than that in the primary saponifying treatment step, preferably pH 10-13 and 50-95 deg.C. The obtained mixture is subsequently separated into the oily phase and the aqueous phase to recover the oily phase. The aqueous phase is simultaneously recycled to the primary and/or the secondary saponifying treatment steps. Furthermore, the aqueous phase after the primary saponifying treatment is concentrated and burned to recover the alkali carbonate, which is then recycled as an alkaline source used for the primary saponifying treatment.

Title: Sputtered magnetic disk medium
Inventor: SUGIYAMA MINORU
IPC: G11B5/82
Filed: 1990-07-03
Abstract: PURPOSE:To improve adsorptivity by giving a grinding texture having a five angle to a reference when the direction of a periphery is set to be reference. CONSTITUTION:The grinding texture 2 is given to the front surface of a sputtered magnetic disk medium 1 and the grinding texture has the five angle 5 to the direction 4 of the periphery. When measurement is executed in the direction 3 of the radius, there is no difference in roughness compared to a conventional case but it becomes rough when measurement is executed in the direction 4 of the periphery. The five angle is satisfactory at about 5-10 deg. and roughness in the direction 4 of the periphery becomes rough for about 1.2-1.5 times. Thus, a roughness level in the direction of the radius is not changed but the roughness level of the direction of the periphery is made rough. The roughness of the front surface effective on adsorption is made rough and the change of the direction of the radius, which has an influence to the electric defect is eliminated and the satisfactory surface can be obtained for the both, whereby adsorption phenomenon can be prevented.

Title: Manufacture of coil spring
Inventor: OOMORI TADAO
IPC: B21F3/00
Filed: 1981-11-05
Abstract: PURPOSE:To improve productivity by performing the stage of coiling a blank material synchronously with the stages of cutting and grinding and finishing end surfaces. CONSTITUTION:To coil a blank material into a coil spring of prescribed length size, end surfaces of the material are ground and finished while cut at a high speed by a cutting grindstone which rotates at a high speed synchronously with the stage of coiling. Then, low-temperature annealing is performed upon occasion. Thus, the grinding and finishing of the end surface are performed simultaneously with the cutting, so the end surfaces are excellent and the stage of grinding the end surface after the low-temperature annealing is unnecesary. Further, successive coiling prevents the crushing of the wire to reduce variance, thereby improving productivity.
