Title: Manufacture of anionic exchange resin
Inventor: TERAUE TAKESHI
IPC: C08F8/44
Filed: 1995-11-28
Abstract: PROBLEM TO BE SOLVED: To obtain an anionic exchange resin with a high strength by causing an aromatic crosslinked copolymer with a haloalkyl group to chemically react with an amine in the presence of at least a specific amount of water and at least a specific amount of water-soluble inorganic salt. SOLUTION: An aromatic crosslinked copolymer with a haloalkyl group is caused to chemically react with an amine in the presence of at least 100 pts.wt. of water for 100 pts.wt. of the copolymer and at least 5 pts.wt. of water- soluble inorganic salt for 100 pts.wt. of water. Thus it is possible to manufacture an anionic exchange resin with high mechanical strength. The aromatic crosslinked copolymer can be manufactured by first, polymerizing an aromatic monofunctional polymerizable monomer with a multifunctional polymerizable crosslinking agent using a radical polymerization catalyst, and then causing this crosslinked polymer to chemically react with a haloalkylating agent in the presence of a Friedel-Crafts catalyst. In addition, it is possible to manufacture the aromatic crosslinked copolymer by copolymerizing the aromatic monfunctional polymerizable monomer with the multifunctional crosslinking agent using the radical polymerization catalyst.

Title: Paper feeder for image forming device
Inventor: TONAI YOSHIHIRO
IPC: B65H1/00
Filed: 1992-11-19
Abstract: PURPOSE:To prevent a machine from being stopped unnecessarily sheet feeding failure is detected, by feeding paper sheets until sheet feeding has been detected or sheet feeding of prescribed frequency has been performed. CONSTITUTION:Paper sheets in sheet cassettes 13-16 are fed to an image forming part 5 one by one by a sheet feeding means 17.

After sheet feeding starts, the sheet feeding means 17 is actuated until sheet feeding has been detected by the detecting means or the operation of the sheet feeding means 17 has reached prescribed frequency. If sheet feeding is not detected even when the operation of the sheet feeding means 17 has reached the prescribed frequency during the operation, an error process is taken. It is thus possible to prevent a machine from being stopped unnecessarily when sheet feeding failure is detected.
