Title: Cutter for surface skin of paper roll
Inventor: KASAHARA TAKAHIRO
IPC: B26D3/00
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To detect such a fact that the real paper on the top layer of a paper roll is surely cut when a surface skin cutter is inserted in the paper roll from the side face to cut the surface skin including a peripheral packaging material and the real paper on the top layer of the paper roll. SOLUTION: A surface skin cutter 15 is inserted in a paper roll 11 from the side face and a surface skin 13 of the paper roll 11 is cut by a rotary scooping cutter 17. A spit 16 of the skin cutter 15 is connected to an upside distinguishing sensor 22 to detect the color of the back of the surface skin 13, and a packaging material remover 25 to be pressed on the side face of the paper roll 11 is connected to a side face distinguishing sensor 26 to detect the color of the side face of the paper roll 11. When the surface skin of the paper roll 11 is cut, signals from the upside and side face distinguishing sensors 22 and 26 are compared with each other. When both signals are the same, it is decided that real paper of the paper roll 11 is surely cut.

Abstract: PURPOSE:To hold the external surface beautifully and smoothly by enabling not only easy peeling-off of a protective tape but also reliable protection of the external surface, by covering the external surface with the protective tape adhering by charging statically. CONSTITUTION:The titled manufacture is so constituted that a protective tape T is drawn out while the same is being made into contact with the inside in a piercing through-hole 12a of an extruding mold 12 or a piercing through-hole 13a of a shoe 13 in a sliding state and the tape T is pressed to weld to the external surface of a molding body M discharged through an extrusion mold 12 by making the tape T charge statically through sliding contact friction. The charge is generated large when tension is applied to the protective tape T to some extent within the piercing through- holes 12a, 13a or on this side of them and it follows that the protective tape T is stuck to the external surface of the molding body M by attracting the same. Sticking and covering of the protective tape T are completed prior to extrusion of the molding body M through an outlet of the extruding mold 12 or an outlet of the shoe 13, and when extrusion molding of the molding body M is performed in a predetermined cross-sectional form the external surface has been covered with the protective tape T already.

Filed: 1990-05-31
Abstract: PURPOSE:To effectively eliminate both of the multipath distortion and an interference wave by extracting an interference component without filtering on the frequency base by subtraction of a desired signal replica from a reception signal and subtracting this interference component from the reception signal after phase control to eliminate the interference wave. CONSTITUTION:A discrimination feedback equalizer 2 eliminates the multipath distortion included in a matched signal outputted from a matching filter 1 to generate a discrimination signal, and a convoluter 3 convolutes an inference impulse response and the discrimination signal to obtain a designated desired signal. A delay element 6 fixedly delays the reception signal, and subtractor 8 takes the difference between the output signal of this element 6 and the inferred desired signal to extract the interference wave component. A correlator 5 takes correlations between the reception signal and the interference wave component to obtain a correlation value, and an AGC amplifier 9 normalizes the amplitude of the correlation value to one to extract the phase of the correlation value. A multiplier 4 multiplies the interference wave component by this phase to obtain an inferred interference wave. Thus, the multipath distortion and the interference wave are effectively eliminated.
