Abstract: A non-evaporation getter material suitable for non-evaporation getters disposed in electron devices, such as fluorescent luminous tubes. The getter material is sized and shaped to more efficiently absorb gases actively at low temperatures.

Abstract: Ultradispersed ones of primary particles of nanometer-sized carbon are obtained by applying a wet-type milling method and/or a wet dispersion method to an aggregate structure of the primary particles to overcome van der Waals forces, by which forces the primary particles are held together to form the aggregate structure, whereby the ultradispersed primary particles are obtained in a colloidal dispersion on a large-scale basis at low cost without using any additive. In a method of manufacturing the ultradispersed primary particles, the wet-type milling method is carried out in a ball mill, preferably in combination with a high-energy ultrasonic-wave process carried out in a dispersing medium such as pure water, whereby a colloidal solution or slurry with a low-concentration of the primary particles ultradispersed in the dispersing medium is obtained.

Abstract: An absorptive article having a superior liquid-absorptivity, without returning of the absorbed body fluid and being compact is provided.which article comprises a liquid-permeable front sheet, a liquid-impermeable back sheet and an absorbent placed between the above two sheets, this absorbent being composed of at least two layers. As those used in the first layer and the second layer in Examples 1 to 3 were mixed to obtain homogeneous absorbents.The preparation conditions, the quantity of liquid absorbed, the percentage of absorbed liquid and the tensile strength after dried, these absorbers are shown in Tables 1 and 2.

Abstract: A raw material prepared by washing a phosphor powder containing a phosphor host material and an activator with an acid solution, followed by drying the washed powder, is heated within a thermal plasma at a temperature which permits partially melting the phosphor, followed by cooling and subsequently subjecting the resultant phosphor at 1200.degree. to 1700.degree. C., thereby manufacturing spherical phosphor particles having a concentration gradient in a radial direction.

Abstract: A vehicle occupant-restraining webbing is used in a seat belt apparatus of a vehicle in which an air bag apparatus is provided as an auxiliary occupant protecting apparatus, and comprises a webbing length increasing section in which a folded portion of the webbing, formed with a portion of the webbing being folded in a longitudinal direction of the webbing, includes first, second and third regions arranged in order from a fold base end to a fold tip end, wherein the first region is formed by stitching and when a first tensile force acts in the longitudinal direction of the webbing and is applied to the first region to undo the stitching of the first region, the length of the webbing is increased, the second region is provided so as to increase the length of the webbing without applying active tensile force in the longitudinal direction of the webbing when the stitching of the second region comes undone, and the third region is formed by stitching and when a second tensile force which is smaller than the first

Abstract: A front body section of a vehicle which is provided with a front-side member and a crush box. The crush box includes a front section and a rear section, which are disposed in front of the front-side member so as to be axially aligned and connected thereto. An upper plate, a lower plate, an outer plate, and an inner plate, all of which form the front section, are prepared so as to provide a lower level of total plastic characteristic, when under load, than those plate members which form the rear section. The crush box thereby exhibits a total plastic characteristic, when under load, in two stages.

Abstract: A stretchable nonwoven fabric is provided, in which a uniform web comprising 70 to 100% by weight of polypropylene base heat-bondable composite fibers and 0 to 30% by weight of other organic fibers and having a web heat shrinking percentage "A" of 50% or lower at 100.degree. C. and a web heat shrinking percentage "B" of 50% or higher at 120.degree. C. provided that a difference "B"-"A" between the latter and the former is 20% or higher, the fibers being uniformly entangled together, has been shrinked as a result of sufficient crimping and more increased entanglement of the above composite fibers imparted through further heat-treatment, and which has an elastic recovery-at-30%-elongation of 80% or higher in both the warp and weft directions. This nonwoven fabric has no density variation, no crease, and excellent stretchability.

Abstract: In preparing superfine particle in a reaction chamber by evaporation-in-gas method or on such processes as PVD or CVD using arc- or high-frequency plasma wherein in the proximity of the inner surface of the said reaction chamber, a vessel provided with a number of pores thereon is arranged and gas consisting of given components is introduced into the space between the inner surface of the chamber and the vessel, and spouted through the said pores on the vessel. The resultant superfine particle produced in the chamber and being in Brownian movement or in thermal migration does not adhere to the surface of the vessel by being separated from the vessel by the spouting gas so that the gas containing superfine particle is directed securely to the collecting path, wherein the vessel is made of the material not reactive with the resultant superfines but resistant to heat.

Abstract: An ignition element for use in igniting a high-frequency plasma torch is ungrounded and displaceable. When a tip end of the ignition element is positioned in a location in a gas to be formed into a plasma, which flows under normal pressure, and a high-frequency energy is applied to the above location in the gas flow, the gas is ignited into a high-temperature plasma in a small period of time shorter than 1 second. After the gas has been ignited, the ignition element is immediately retracted out of the location. The ignition element may be in the form of an ignition rod of metal or an ignition tube of quartz or the like. Where the ignition rod is used, it instantaneously contacts the high-temperature plasma upon ignition so that the high-temperature plasma is of high purity consisting only of the component of the gas. The ignition tube may be used for producing a high-temperature plasma of higher purity on and after ignition. The ignition tube is employed while a pressure therein is reduced.
