Abstract: PURPOSE:To reduce the influence of vibration by interposing a damping elastic body between a motor or a clamper and the other member. CONSTITUTION:A disk 6 such as an optical disk is installed on a turn table 5, and it is sandwiched and held between the turn table 5 and the clamper 7. The clamper 7 has a magnet, for example, and it is attracted to the turn table 5 through the disk 6. The damping elastic body 11 is installed on the clamper 7 and a restriction member 12 having constant mass (m) is installed on said body 11 in a free state. The damping elastic body 11 is manufactured by viscoelasticity material whose vibration resistance is high such as butyl rubber or the other elastic material, and the damping elastic body 11 is sandwiched between the clamper 7 and the restriction member 12. Then, both surfaces of the elastic body are adhered to the clamper 7 and the restriction member 12. Thus, the transmission of vibration whose amplitude is large for pickup can be prevented.

Title: Method for estimating welding quality in resistance welding
Inventor: HANEDA OKITOSHI
IPC: B23K11/24
Filed: 1994-04-22
Abstract: PURPOSE:To obtain a better non-destructive method for controlling quality of resistance welding. CONSTITUTION:A correlation between an electrode displacement quantity and welding strength meeting the number of spotting is previously determined by using a welding machine of an actual line. Measurement of the electrode displacement quantity during welding and pulling test are executed with the same current in this continuous spotting test. The acquired data are converted to a data base. The correlation between the electrode displacement quantity and the welding strength is plotted to a graph. The number of spotting times at which the correlation changes largely is determined from the resulted data and a mold parting line at this number of spotting times is analyzed. The welding strength of the resistance welding obtd. in an actual welding stage is estimated to approximately coincide with the acquired data and is used for quality control. A test sample is taken out at the point of the time when the correction changes and the welding strength thereof is investigated at the time of using the data actually in the welding stage line. This information is left as the data base and is fed back. As a result, verification as to whether the point of the time when the correction changes is correct or not is subsequently executed.
