  • Patent number: 11064726
    Abstract: An extraction method of a flavor constituent comprises: a step A for heating a tobacco raw material which is subjected to an alkali treatment; and a step B for bringing a release component released in the gas phase in the step A into contact with a collection solvent at normal temperature until any time from when a first condition is satisfied to when a second condition is satisfied. The total amount of saccharides contained in the tobacco raw material is 9.0 wt % or less when a gross weight of the tobacco raw material in the dry state is 100 wt %. The first condition is determined based on variations in the pH of the collection solution. The second condition is determined based on the remaining amount of nicotine component.

  • Patent number: 10955012
    Abstract: An electromagnetic connecting device includes a flange of a hub, an armature supported by the flange via a leaf spring, a rotor accommodating an electromagnetic coil, and an anti-vibration member. When an electric current is supplied to the electromagnetic coil, the armature moves in the axial direction of the hub against the spring force of the leaf spring, and is attracted to the rotor. The leaf spring includes a moving portion that moves in the axial direction together with the movement of the armature. The anti-vibration member is fixed to the moving portion of the leaf spring. The anti-vibration member includes a stopper that comes in contact with the flange, and a damper that comes in contact with the armature. With this configuration, an electromagnetic connecting device capable of reducing an impact sound both when the armature is attracted and released can be manufactured at a low manufacturing cost.
