Title: Method of stainproofing sealing material surface
Inventor: OTOSHI YUKIO
IPC: C09K3/00
Filed: 1989-07-19
Abstract: PURPOSE:To prevent the deposition of contaminants on an uncured surface of sealing material by applying an acrylate polymer containing a polyfluoroalkyl group to the uncured surface of a sealing material made of a thermosetting resin. CONSTITUTION:An acrylate polymer containing a 3-21C polyfluoroalkyl group (Rf group) is applied to an uncured surface of a sealing material made of a thermosetting resin.

Title: Method of controlling paper-feed in copying machine
Inventor: SHINKAI MICHIO
IPC: B65H7/18
Filed: 1983-10-03
Abstract: PURPOSE:To feed papers with appropriate timing, by measuring a required time for which a paper reaches a predetermined position between a stacker and its aligning position. CONSTITUTION:When a reference signal is delivered to a control section 12, the control section 12 energizes an electro-magnet clutch 2 at a time t1 to discharge a paper 5. When the paper 5 passes just above a position detecting sensor 13 disposed in the vicinity of a register roll 11 at a time t2, the control section 12 computes a required time Td=t3-t1, and the detecting time Td is subtracted from a nominal reaching time T which is previously stored, so that a time difference DELTAT=T-Td is calculated. When the reference signal is delivered to the control section 12 so that the paper is discharged, the time at which the electro- magnetic clutch 2 is energized is compensated from t1 to t1+DELTAT. The timing of paper-discharge is compensated as mentioned above so that papers always reaches their aligning position with predetermined timing.
