Title: Paper sheet exfoliating device
Inventor: HASHIZUME EIJI
IPC: B65H9/20
Filed: 1990-01-25
Abstract: PURPOSE:To prevent a paper sheet from being diagonally fed by providing a plurality of driving means of driving each exfoliation roller, detecting means of detecting a diagonal feed of the exfoliated paper sheet and a control means of controlling each driving means in accordance with a detection result. CONSTITUTION:In the case of diagonally feeding a paper sheet 12 by exfoliating action by pusher rollers 6a, 6b and a delivery roller, a point end of the paper sheet 12 is detected first by a sensor 1b and successively by a sensor 1a, while a time difference calculating device 2 feeds to a control part 3 an input time difference between detection signals of both the sensors 1a, 1b to communicate information about the paper sheet 12 diagonally fed. The control part 3 outputs a drive signal to drive motor control parts 4a, 4b so that a feed amount of the paper 12 by the roller 6a is increased larger than the feed amount of the paper by the roller 6b in accordance with the input time difference from the calculating device 2. Accordingly, a pusher roller drive motor 5a is drive-rotated so that a rotational speed of the roller 6a is increased larger than a rotational speed of the roller 6b by a control of a control part 4a.

IPC: H01J49/10
Filed: 1983-02-02
Abstract: PURPOSE:To isolate atoms and molecules migrating along the surface, keep clean the surface of a sample and analyze carbon and oxygen included in the sample with high sensitivity by irradiating the ion beam radiating part with a laser beam. CONSTITUTION:In the figure, 3 is a laser beam used for irradiating the sputter surface of a sample 4. Atoms and molecules migrating along the surface of sample 4 are usually physically attracted weakly by the van der Waals forces. It is said that the activated energy moving on the surface of sample 4 is 0.1- 1kcal/mol. Meanwhile, since the light of 1eV corresponds to 11.600k in terms of thermal energy, it gives energy which is sufficient for atoms and molecules to be isolated from the surface of sample 4. Accordingly, when the area to be sputtered by ion is irradiated by laser beam before and during the sputtering, oxygen and carbon etc. are isolated from the surface and moreover inflow of new atoms and molecules can also be prevented.
