Abstract: A regenerated tobacco material is manufactured through extracting a natural tobacco material with an extracting solvent to obtain an extracted solution containing components of the natural tobacco material and an extraction residue. A regenerated tobacco web is prepared by using the extraction residue. On the other hand, the extracted solution is subjected to a fractionating treatment by means of ultrafiltration, reverse osmosis filtration, or reversed-phase partition chromatography to obtain a first fraction enriched in desired components and depleted in undesired components, and a second fraction enriched in the undesired components and depleted in the desired components. The first fraction is added, optionally together with the second fraction decreased in amount, to the regenerated tobacco web to prepare a regenerated tobacco material.

Abstract: A data-related information acquiring device acquires data related information having a distribution information. The distribution is related to the distribution of data. A data identification device identifies first data of which first distribution time extends or contracts on the basis of the data related information and second data of which second distribution time is changed by the extension or contraction of the first distribution time of the first data. A distribution-state display controlling device controls display information, which suggests a change in each of the distribution times in addition to the distribution information of the first data and the second data.

Abstract: A cigarette is provided with a tobacco section including a tobacco filler rod wrapped with an inner wrapper paper sheet containing less than 4% by weight of calcium carbonate and an outer wrapper paper containing calcium carbonate in an amount of 30 g/m2 and a burn adjusting agent in an amount of 3% by weight or more.

Abstract: A buckle pivotally arranged in a movable clamp 12 of a first tube holder 1 is attached with play to a buckle 120 pivotally arranged in a movable clamp 82 of a second tube holder 2. When tubes are held in the first and second tube holders 1 and 2, release of the tubes from the holders 1 and 2 is prevented by a movement of a plunger 203 in correspondence of excitation and demagnetization of a solenoid 202 for a predetermined period of operation of the apparatus after holding the tubes (i.e., for a period required from the locking of the buckle 120 until the completion of moving-down of a wafer holder).
