Patent number: 6670588Abstract: An inverter in which the three-phase power source is used as an input power source and the single phase voltage is outputted, is provided. The single phase output voltage of the inverter is applied onto the inductive coil of the inductive heat generation mechanism provided inside the rotating roller as the exciting voltage. Because the single phase voltage obtained by being phase-converted by the inverter is used, the unbalance is not generated among the phases of the three-phase power source which is the input power source.Type: GrantFiled: December 7, 2000Date of Patent: December 30, 2003Assignee: Tokuden Co., Ltd.Inventors: Yoshio Kitano, Kozo Okamoto, Yukio Horie

Patent number: 6437301Abstract: In an induction heating roller apparatus of the present invention, Rolling bearings 10 and a sliding bearings 14 are provided between drive shafts 2 of a roller body 1 and a support rod 9. When a trouble occurs in the rolling bearings 10, a rotational torque is transmitted from the drive shafts 2 through the rolling bearings 10 to the support rod 9. The sliding bearings 14 operate during the transmission of the rotational torque to the support rod 9, and the rolling bearings 10 slips relative to the support rod 9. The slip prevents that the support rod 9 co-rotates with the drive shafts.Type: GrantFiled: September 27, 2000Date of Patent: August 20, 2002Assignee: Tokuden Co., Ltd.Inventors: Yoshio Kitano, Kozo Okamoto, Yukio Horie

Patent number: 4011641Abstract: The first-state jacketed roller in an apparatus for spin drawing synthetic fiber comprises a roller rotatably mounted on a shaft and encompassing a fixed, non-rotatable inner core. The roller includes an electrically conductive tubular member coaxial with, and hermetically affixed to, the inner wall of the roller. A plurality of bore holes extend in the conductive member parallel to the roller axis and are coextensive therewith, and a heat transfer fluid fills each bore hole. The fluid divides into a liquid and a vapor phase when the roller is heated and rotation of the roller forces the liquid phase outwardly under centrifugal force into engagement with the outer portion of each bore hole.Type: GrantFiled: January 2, 1975Date of Patent: March 15, 1977Inventors: Yoshio Kitano, Takuma Katsumata
