Title: Method for detecting abrasion quantity of bush of pump shaft
Inventor: NOGUCHI NOBUHISA
IPC: G01B5/00
Filed: 1990-11-27
Abstract: PURPOSE:To accurately detect abrasion quantity on the basis of proper measured data by storing only the max. displacement within a predetermined period among the detection values of the displacement in the radius direction of a rotary shaft in the vicinity of a bush. CONSTITUTION:The clearance C between a rotary shaft 13 and a bush 12 is detected by a non-contact type displacement sensor 14 and sent to an operational processor 15 to be subjected to the comparative operation with the displacement corresponding to the initial clearance or the displacement corresponding to a limit clearance. When the max. detection value is larger than the initial displacement, the abrasion of the bush 12 is judged to be generated to store the value of abrasion. Thereafter, the displacement of the next period is detected in the same way to be subjected to comparative operation and the stored value is rewritten if necessary and, when the value of abrasion exceeds the displacement corresponding to the limit clearance, an alarm is emitted. By this method, the abrasion quantity of the bush can be accurately detected and it can be also prevented that measured data becomes excessive.

Title: Production of alumina substrate
Inventor: KAJIYOSHI KOUJI
IPC: C04B35/10
Filed: 1988-12-20
Abstract: PURPOSE:To obtain an alumina substrate having the surface with a high level of smoothness by mixing alpha-Al2O3 with gamma-Al2O3 having a specified particle diameter at a prescribed weight ratio, adding a binder and organic solvent thereto, forming the resultant mixture into the shape of a sheet and calcining the formed sheet. CONSTITUTION:gamma-Al2O3 having 0.01-0.1mum particle diameter in an amount of 5-50wt.% is added to alpha-Al2O3 having 0.1-0.5mum average particle diameter and a binder (e.g. polyvinyl butyral) and an organic solvent are further added and mixed therewith. The obtained mixture is then formed into the shape of a sheet to provide a green sheet, which is then calcined to afford an alumina substrate. Thereby, since the particles of the gamma-Al2O3 fill interstices between the particles of the alpha-Al2O3, the surface of the resultant alumina substrate has a high level of smoothness. Furthermore, the particles of the gamma-Al2O3 are subjected to phase transition to the alpha-Al2O3 at about 1300 deg.C temperature and the particles grow in the process. As a result, calcining is preferably carried out at about 1250-1300 deg.C temperature.
