  • Patent number: 6991163
    Abstract: A card reader that transports a card having a magnetic strip with a drive means to read and write information on the card that includes prehead for detecting the insertion of the card by searching the presence of the magnetic information recorded on the magnetic strip, and a card detecting switch for detecting the card. When the card detecting switch determines that a card is present, the prehead searches the magnetic information. When the card detecting switch does not detect a card, the card is distinguished as a specially-shaped card.

  • Patent number: 6574058
    Abstract: 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.

  • Patent number: 5597879
    Abstract: 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.

  • Patent number: 5306790
    Abstract: 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.
