Title: Sheet roll and its package
Inventor: ITO SADAMI
IPC: B65D75/04
Filed: 1989-03-02
Abstract: PURPOSE:To permit the winding beginning of a following sheet to be automatically projected to the outside by the winding end of a preceding sheet by winding a plurality of sheets one by one with each sheet overlapping at its end. CONSTITUTION:To unpack the subject package, the conventional unpacking means such as tear-strip attached to one edge of a bag 8 and V-shaped notch formed on a seal part in the longitudinal direction of a bag is used. The forefinger is thereafter inserted in the center of exposed sheet winding body 7, i.e. a hollow 5 formed by a first sheet 1 to draw it out. Since this drawing action makes the winding diameter of the first sheet 1 slightly smaller due to the absence of winding core, the winding beginning 2A of a second sheet 2 is gripped between the winding end 1B of the first sheet 1 and the second sheet 2 and the resulting contactual friction force permits the winding beginning 2A of the second sheet 2 to be partially projected following the winding end 1B of the first sheet 1. Therefore, the second sheet 2 and the subsequent sheets can ba drawn out by being clamped between the fingers.

Abstract: PROBLEM TO BE SOLVED: To reduce the influence caused by eliminating a non-principal wave component by selecting a numerical series that has the least numerical amplitude among plural distributed numerical series and defining the timing containing the selected numerical series as the symbol timing. SOLUTION: The N sets of numerical series R0, R1...RN-1 which are stored in a two-dimensional register 107 of (N sets × F stages) are read out by N sets of arithmetic circuits 108 which calculate the rates Ti (i=0, 1...N-1) between two main waves showing the largest value and the second largest value of received signals and the absolute value of a correlative series for those numerical series respectively. A largest value retriever 109 retrieves the largest value of the rate Ti calculated between two main waves and the absolute value of the correlative series for each of series R0 to RN-1. Then (i) having the largest Ti is defined as i0 with a sample point where the remainder is i0 when N is divided by (n) defined as the symbol timing respectively, and i0 is outputted via an output terminal 110.  Thus, the timing that contains a numerical series having the least numerical amplitude is defined as the symbol timing.
