Title: Paper feeding device
Inventor: HASHIURA SHIGERU
IPC: B65H3/06
Filed: 1996-07-25
Abstract: PROBLEM TO BE SOLVED: To solve the dispersion in size of curved deflection of sheets and reduce the paper feeding noise without complicating an equipment by setting the paper feeding speed constant, and setting a card detecting sensor in a position closer to a resist roller than a thin paper detecting sensor. SOLUTION: Only one printing sheet 8 is carried toward a resist roller 4 along a carrying guide 6a by a separating carrying means 5. Since a paper feeding device 3 has a control means, the corresponding one of a thin paper detecting sensor 12 and a card detecting sensor 13 is selected on the basis of the judgment of kind of the printing sheet 8. When the top end of the printing sheet 8 is detected by the selected sensor, a feed roller driving motor is stopped by the control means, but the sheet is slightly carried by the inertial force, and stopped while forming a proper curved deflection after the top end touches the nipping part of a resist roller 4 which is not rotated at this time. Since it is detected just before the nipping part, the curved deflection has a uniform and proper size.

Title: Monitoring method for natural oxidized film presence and absence
Inventor: FUKUI AKIYOSHI
IPC: G01N23/22
Filed: 1988-08-05
Abstract: PURPOSE:To easily monitor whether or not there is a natural oxidized film on the surface of a semiconductor substrate by irradiating the surface of the semiconductor substrate with ultraviolet rays and measuring the quantity of photoelectrons emitted from the semiconductor substrate surface. CONSTITUTION:The semiconductor substrate 1 is installed on a semiconductor substrate support table 2 and the surface of the substrate 1 is irradiated with the ultraviolet rays. In this case, photoelectrons are emitted unless the natural oxidized film is present on the surface of the substrate 1 and gathered to a collector 4 and an ammeter 5 measures the quantity of the photocurrent. When the natural oxidized film is present on the surface of the substrate 1, no photoelectron is emitted and the amount of the photoelectron measured by the ammeter 5 is zero. Therefore, whether or not there is the natural oxidized film on the surface of the substrate 1 is easily monitored from whether or not the photocurrent flows.
