Abstract: A metal bellow tube has sectional shapes of a ridge and a valley in a bellows-shaped tube wall of a metal bellows tube that are made to be V-shaped. As a result, a metal bellows tube with significantly improved bending fatigue resistance compared to conventional ones is provided. In addition, by this metal bellows tube and a tubular metal braid covering the outside of the tube, a flexible tube for a high-pressure fluid can be constituted. Consequently, a high-pressure fluid exceeding 20 MPa, particularly even a superhigh-pressure fluid of 70 MPa, can be transferred safely without transmitting the molecules of the fluid.

Abstract: The gel liquid quenching and deodorizing compositions for cigarettes, which comprise water, a deodorizing agent, a water-absorbing polymer or thickener and a viscosity-imparting agent and exhibit excellent quenching and deodorizing effects for a long time are discussed. Due to their gel form, the compositions can offer effects in that they can be used in shaky vehicles and ashtrays can be cleaned easily after use by letting the content enveloped therein fall out.
