Title: Rolled paper supply device
Inventor: ISHIDATE YOSHIYUKI
IPC: G03G15/00
Filed: 1983-06-03
Abstract: PURPOSE:To prevent the leading end part of a rolled paper from slacking, by exerting braking force to the leading end part of the rolled paper in association with the closing of a door in an apparatus incorported therein with a rolled paper supply device. CONSTITUTION:When a door 4 is opened, a rolled paper 1, a pinch roll 7 and a feed roll 8 are exposed with a press roll 16 being separated from a brake roll 13, and therefore, the replacement of the rolled paper 1 may be simply made without being hindered by the press-roll 16. When the door 4 is closed, the press roll 16 abuts against the brake roll 13 in association with the motion of the door 4 to compress a constant pressure coil spring 11 so that the brake roll 13 and the press roll 16 produce braking force due to the spring force of the spring 11. With this arrangement the rolled paper leading end 1a is not slacked, thereby paper-jamming due to oblique feeding, zigzaging and deviation of the paper may be prevented.

Filed: 1997-04-16
Abstract: PROBLEM TO BE SOLVED: To obtain a manufacturing method for composite wires by which the wires are efficiently produced and manufacturing man-hours are reduced by improving the strength of interfacial adhesion between aluminum and zinc and strength of ductility of a plating layer. SOLUTION: A stage (Step S1) for preprocessing a steel wire is executed, next, a stage (Step S7) for coating the steel wire with aluminum and zinc is executed and, at last, a wire stranding stage (Step S6) is executed. In the stage for coating the steel wire with aluminum and zinc, aluminum and zinc are coated in one process by extrusion. Consequently, as compared with a conventional method, the stage for coating only zinc is eliminated and the manufacturing man-hour is reduced. By extruding process at the coating stage (Step S7), the interfacial between aluminum and zinc is pressure-welded by extruding pressure and preheating, deformation heat or the like of a composite billet, so the strength of interfacial tight adhesion is improved so as to be strong. Zinc also becomes worked structure whose crystal grain is refined by extrusion, so ductility is raised.

Title: Spread spectrum receiver
Inventor: ENDO YOSHINORI
IPC: H04J13/00
Filed: 1990-04-16
Abstract: PURPOSE:To reduce the synchronization acquisition time by utilizing positively a synonym phenomenon caused when an inverse spread signal obtained resulting from applying inverse spread processing to a spread spectrum signal is digitized by a down-sampling method. CONSTITUTION:When an inverse spread signal is digitized by a downsampling method in a spread spectrum receiver, a high frequency component is looped back and restores to a frequency within a frequency band less than a half of the sampling frequency. This is referred to as a synonym phenomenon. Thus, a noise signal is eliminated by a synchronizing signal detection filter 12 from the digitized signal in this way. The processing for synchronization establishment is implemented and when the synchronization is not established, the frequency search is tried for a frequency range below a half the sampling frequency and the synchronization is established. When the band width of the filter 12 is variable, the band width is made wide before the synchronization establishment to allow the synchronization to be easily established and the band width is made narrow after the synchronization establishment to a degree that an inverse spread signal is able to be passed. As the band width of the filter 12 gets narrower, the S/N of the inverse spread signal is improved.
