Patent JP-2947864-B2 (JP)
IPC: B65D85/672

Granted: 1999-09-13
Abstract: A compact, low shipping volume paper product comprising a compression loaded, core-wound roll of paper and a compression constraining element; and concomitant method of making such a paper product. The roll comprises a length of paper which is wound on a tubular core, and which roll may have an obround or parallelopipedal shape due to being unidirectionally compressively loaded after winding; and then constrained against expanding by a suitable constraining element. Preferably, the roll is sufficiently compressively loaded to completely flatten the core. In another aspect of the invention, the roll may be further compressed by applying a compressive loading that is substantially greater than that needed to cause the core to become flat; and, some of that high compressive loading may be relieved before the constraining element is applied or secured. The paper product is susceptible to being reshaped by a consumer upon removal of the constraining element so that both the product and the core become somewhat round in cross section. Such a product may, for example, be a contemporary roll of toilet tissue or disposable paper towels on a contemporary paperboard core. The paper product may comprise a plurality of such rolls, and may be constrained by enclosures such as polyethylene film, and/or bands about individual rolls, and/or a band about an array of rolls.

Abstract: In accordance with the present invention, for noise cancellation, a reference noise signal is input to signal-to-noise (SN) power ratio estimating circuitry via a reference signal input terminal. The SN power ratio estimating circuitry causes its adaptive filter for producing a pseudonoise signal from the reference noise signal to operate. The circuitry detects error signal power and pseudonoise signal power out of the pseudonoise signal and other signals, and then outputs an estimate of an SN power ratio based on the detected power. A first delay circuit is connected to the output terminal of the above circuitry. A comparator compares an estimate of an input to and an estimate of an output from the first delay circuit, and produces greater one of the two estimates as an expanded estimate. A step size output circuit controls, based on the expanded estimate, the step size of a second adaptive filter connected to the reference signal input terminal via a second delay circuit. A subtracter subtracts a pseudonoise signal output from the second adaptive filter from a received signal sequentially delayed by a third and a fourth delay circuit, thereby cancelling a background noise signal component contained in the received signal.
