Title: Polishing and grinding tool
Inventor: NODA SATOSHI
IPC: B24D3/10
Filed: 1984-10-25
Abstract: PURPOSE:To permit the work with high precision by permitting the uniform abrasion of grindstone and suppressing the change of the shape of the polishing surface of a tool by using the abrasive material, as polishing and grinding tool, in which regions having the different constitution of the content of gas foams in the abrasive material and said regions are arranged in concentric and annular form around the revolution shaft to the tool. CONSTITUTION:A tool 11 is constituted of the regions 12-14 of the polishing material having the different density of gas foams whose volume is nearly equal, and the regions 12-14 are joined integrally into concentric annular form around the revolution shaft O of the tool, and when the gas-foam density C in each region is 12a-14a, the relation 12a>13a>14a is established. The magnitude of the gas-foam density exerts an influence onto the magnitude of the polishing area of the polishing material, and the abrasion amount of the polishing tool can be controlled. In other words, since the region 12 as the center part of the polishing surface of the tool 11 has the highest gas-foam density C, the degree of abrasion at the upper edge is large, and since the region 14 as the abrasion surface of the peripheral part has the lowest gas-foam density C, the degree of abrasion is little. Therefore, each abrasion amount of the peripheral part and the center part can be made equal by setting the distribution of gas-foam density, and the precision can be improved.

Title: Correction method of center offset between upper and lower shafts for bucket elevator
Inventor: ARAI SEIGOU
IPC: B65G23/44
Filed: 1982-12-22
Abstract: PURPOSE:To make a center offset correctable in an easy manner, by correcting the position of one side shaft to the other side one by means of a variation in the number of liner sheets to be disposed between a base plate supporting both upper and lower shafts and a casing and so on. CONSTITUTION:When there is an axial offset between upper and lower shafts, the number of liners lying between the side of a lower side housing 3 and a base plate 4 being opposite to the former is increased so as to cause the offset direction to be corrected to the opposite side whereby the number of liners at the opposite side is decreased. With this method, a lower shaft 9 shifts in an axial direction and the axial offset between these upper and lower shafts is corrected right. Likewise, when the degree of parallelism inside a horizontal surface of centers of both shafts goes wrong, loosing a bolt 20 to some extent as necessary, then the base plate 4 is shifted in a B direction, making the shaft 9 rotate inside the horizontal surface, and the parallelism between shaft centers is thus trued up. With this constitution, the center offset can be easily corrected with a simple construction.
