Abstract: The present invention addresses the problem of providing: a filter in which a liquid having phenol filtration capability is prevented from leaking out even after prolonged storage; and a flavor inhalation article equipped with said filter. The problem is solved by a filter that is for a flavor inhalation article, and that has a filtering medium including a biodegradable material, and a paper roll wound around the filtering medium. The filtering medium contains a liquid having a phenol filtration capability. A surface of the roll paper where a contact is made with the filtering medium is made of a layer exhibiting liquid-repellent properties with respect to said liquid.

Abstract: A low ignition propensity cigarette according to the invention includes a high-density region formed in the center of the paper tube and containing normal shred tobacco filled to be a filling density of 0.15 to 0.35 g/cm3, for example 0.25 g/cm3, and a low density region formed between the paper tube and the high-density region and containing expanded shred tobacco filled to a filling density of 0.05 to 0.15 g/cm3, for example 0.14 g/cm3. The thickness of the low-density region defined between the paper tube and the high-density region is in the range of 1 to 3 mm.

Abstract: A process for producing a cigarette paper exhibiting a low ignition propensity, includes applying a first aqueous solution containing divalent cations to a base wrapping paper on a whole of its one surface, and applying a second aqueous solution containing a water-soluble gellable substance capable of gelling under the action of the divalent cations to at least a part of the surface of the base wrapping paper having the first aqueous solution applied thereto to thereby cause the gellable substance to gel and thus form a combustion-inhibiting substance consisting of the gel.

Abstract: A cigarette comprises a tobacco section including a columnar tobacco filler material and at least one cellulose-based wrapping paper sheet for wrapping the outer circumferential surface of the columnar tobacco filler material. The outermost wrapping paper sheet among the wrapping paper sheets has a thermal conductivity not lower than 0.5 W·K?1·m?1.

Abstract: A cigarette includes a tobacco filler material rod and a cigarette paper wrapping the rod. The cigarette paper has an inherent air permeability of more than 20 CORESTA units but 80 CORESTA units or less and contains a loading material in an amount of 1.0 to 5.0 g/m2.

Abstract: Wrapper paper for a smoking article carries 1 g/m2 to 15 g/m2 of a burn adjusting agent and 1 g/m2 to 30 g/m2 of a calcium phosphate-based compound in the wrapper paper.

Abstract: A low fire-spreading cigarette has a tobacco section including a columnar tobacco filler material, an inside wrapper paper sheer wrapping the outer circumferential surface of the columnar tobacco filler material and an outside wrapper paper sheet wrapping the outer circumferential surface of the inside wrapper paper sheet. The heat conductivity of the inside wrapper is 0.5 W·K?1·m?1 or more and the heat conductivity of the outside wrapper paper sheet is less than 0.5 W·K?1·m?1.

Abstract: A smoking article is manufactured through supplying a tobacco filler material onto a tobacco wrapping paper sheet that is transferred, wrapping the tobacco filler material supplied onto the tobacco wrapping paper sheet with the tobacco wrapping paper sheet so as to prepare a rod body, and cutting the rod body into a plurality of tobacco rods each having a prescribed length. The tobacco filler material contains at least 20% by weight of expanded tobacco material. The tobacco wrapping paper sheet is coated with the burn adjusting agent during transfer of the tobacco wrapping paper sheet.

Abstract: A low ignition propensity cigarette according to the invention includes a high-density region (6) formed in the center of the paper tube (2) and containing normal shred tobacco filled to a filling density of 0.15 to 0.35 g/cm3, for example 0.25 g/cm3, and a low-density region (8) formed between the paper tube (2) and the high-density region (6) and containing expanded shred tobacco filled to a filling density of 0.05 to 0.15 g/cm3, for example 0.14 g/cm3. The thickness of the low-density region (8) defined between the paper tube 2 and the high-density region (6) is in the range of 1 to 3 mm.

Abstract: Wrapper paper for a smoking article carries 1 g/m2 to 15 g/m2 of a burn adjusting agent and 1 g/m2 to 30 g/m2 of a calcium phosphate-based compound in the wrapper paper.

Abstract: A wrapper paper for a smoking article, which permits decreasing an amount of visible sidestream smoke of tobacco, contains at least 30 g/m2 of calcium carbonate and at least 3% by mass of a burn adjusting agent.

Abstract: A cigarette comprises a tobacco section including a columnar tobacco filler material and at least one cellulose-based wrapping paper sheet for wrapping the outer circumferential surface of the columnar tobacco filler material.

Abstract: An electrostatic motor for use as a power generating mechanism to be mounted on a micromachine includes a rotatable semiconductor substrate and a drive electrode disposed in proximity to the substrate. The semiconductor substrate is doped with a specified impurity element to form electromagnetic wave-static electric converters of p-n junction. When the motor is to be started, the converter in the vicinity of the electrode is irradiated with electromagnetic waves to set up an electric field between the opposed surfaces of the converter and the electrode to rotate the substrate by an electrostatic force due to the electric field.
