Patent number: 6574058Abstract: A technique for detecting a magnetic recording medium such as a strip on a magnetic card so as to distinguish between a case where a magnetic strip has high coercivity and one where it has low coercivity. A magnetic head detects the existence and appropriate positioning of a magnetic strip which is then fed to a permeability sensor that provides an output signal that is a function of the permeability magnetic strip. A circuit responsive to the output of the permeability sensor provides an output signal indicating the high coercivity strip when the permeability sensor output is low and indicating a low coercivity strip when the permeability sensor output is high.Type: GrantFiled: November 22, 1999Date of Patent: June 3, 2003Assignee: Sankyo Seiki Mfg.

Patent number: 5597879Abstract: There is disclosed a process for continuously producing a highly syndiotactic styrenic polymer by using a horizontal self-cleaning type reactor which comprises feeding into the reactor, a catalyst or both the catalyst and a styrenic monomer dividedly into at least two portions, preferably 2 to 5 portions in the direction of the axis of the reactor. The above process facilitates the control for the reactor inside temperatures because of the stepwise feeding of the catalyst (and the styrenic monomer) and remarkably enhances the productivity by simply increasing the feed rates of the catalyst and the styrenic monomer, thus making itself industrially highly valuable.Type: GrantFiled: September 5, 1995Date of Patent: January 28, 1997Assignee: Idemitsu Petrochemical Co., Ltd.Inventors: Hisashi Ase, Kazutoshi Ishikawa, Hideki Imabayashi

Patent number: 5306790Abstract: There is disclosed a process for continuously and efficiently producing a styrenic polymer having a high degree of syndiotactic configuration which comprises effecting polymerization reaction by continuously introducing a styrenic monomer and a polymerization catalyst into a polymerization reactor, the inside of which has been brought into fluidized state by particles previously fed therein, which process is characterized in that the polymerization reactor temperature is controlled by vaporizing a part of the styrenic monomer which has been introduced into the polymerization reactor, while the inside of the reactor is maintained under reduced pressure. According to the above process, such problems as difficulty in polymerization reactor scale-up, adhesion of polymer to the reactor inside and polymer particle agglomerate are simultaneously solved, and thereby the industrial significance of the process is remarkably enhanced.Type: GrantFiled: September 30, 1992Date of Patent: April 26, 1994Assignee: Idemitsu Petrochemical Co., Ltd.Inventors: Hideki Imabayashi, Kazutoshi Ishikawa, Yoshihiko Ishida
