Title: Inclination detector
Inventor: KOMI HISAYOSHI
IPC: G01B7/00
Filed: 1986-02-18
Abstract: PURPOSE:To make it possible to measure the normal line and distance of a surface to be measured even in the vicinity of a sharply bent area, by eccentrically rotating the distance sensor, which is provided at a position taking predetermined eccentric quantity from the center of rotation of a measuring shaft, at the leading end part of the measuring shaft. CONSTITUTION:An inclination detector 1 is set at a position where the measuring shaft 3 thereof becomes almost vertical to a surface S to be measured. Next, by rotating a motor 5, the measuring shaft 3 is rotationally driven through a drive gear 6 and a gear 4. By this operation, a distance sensor 9 performs rotary motion having predetermined eccentric quantity R as a radius around a center line A. If the surface S to be measured is not vertical to the center line A, the distance D up to the surface S to be measured along a center line B changes cyclically during the rotation of the sensor 9. The sensor 9 and an amplifier 9a proportionally converts the change in the distance D to electrical analogue quantity to send the same to a calculator 8 which in turn operates the direction and magnitude of a normal line error from the output signal from the sensor 9 generated in accordance with the distance from the surface S to be measured and the signal corresponding to a rotary phase.

Title: Method of preventing damages to roller bearings
Inventor: TAKEZAWA KOHEI
IPC: F16C19/34
Filed: 1999-02-12
Abstract: PROBLEM TO BE SOLVED: To prevent generation of damages by filling low-melting point fats and oils in a clearance between both axial ends of a roller and an inner race. SOLUTION: Since a roller 1 is held by a holder, although it does not fall in assembling and disassembling since the holder necessarily has a play, the roller can freely move and rotates in the axial direction. In order to prevent the generation of damages due to the axial movement of the roller, a clearance between both end surfaces of the roller 1 and an inner race 3 is filled with low-melting point fats and oils so as to fix or constrain the roller 1 by viscosity so as to prevent the movement thereof. By assembling and disassembling a bearing while practically fixing the roller 1, damages to the race surface of the bearing due to the axial movement of the roller can be prevented.  When use of the bearing is started after assembling the bearing again, since the low- melting point fats and oils is naturally melted by the heat generated in the bearing with start of the operation and replaced with the lubricating oil, having no adverse effects on the bearing.
