    • It is an object of the present invention to provide a quench-hardening testing method in which the quench-hardened depth of a quench-hardened layer and the quench-hardening pattern in inner and outer circumferential surfaces of hollow and solid parts can be measured through non-destructive inspection. A quantity of change in size, between before and after quench-hardening, of a hollow or solid member subjected to quench-hardening treatment in at least one of inner and outer circumferential surfaces of the member is measured, and the measured quantity of change is compared with a pre-measured quantity of change in size of a good member or a value obtained by a comparative calculating operation in accordance with a predetermined algorithm on the basis of the measure quantity of change is compared with a predetermined value of the good member to thereby judge the state of quench-hardening. Thus, even in the case of parts complicated in shape or even in the case of small size hollow parts, the quench-hardened depth of a quench-hardened layer and the quality of the quench-hardening pattern of the parts can be measured through non-destructive inspection.

    • Distilling tube apparatus for converting salt water such as sea water into fresh water is provided. The apparatus includes a first tube through which a feed stream of heated salt water is caused to flow, the first tube being constructed of a porous material which is both water-vapor permeable and liquid water impermeable, which tube allows water vapor to permeate through its walls thereof when heated salt water flows therethrough, the vapor then condensing outside of the first tube upon cooling of the vapor thereat. This first tube is preferably constructed of porous, expanded polytetrafluoroethylene. A second tube oriented in generally parallel relationship and in close proximity to the first tube is provided through which cooling water is caused to flow. The cooling water is maintained at a temperature lower than that of the heated salt water, thereby resulting in a lowering of the temperature of the surroundings of the second tube and providing an enhanced driving force for distillation of the salt water. A third housing tube is provided which houses both the first tube and the second tube within its interior. This housing tube has a plurality of spaced apart openings in the wall thereof to permit fresh water which has condensed externally to the first tube and within the housing tube to flow through these openings and thence outwardly of the distilling tube apparatus.
    • 提供了将咸水等咸水转换成淡水的蒸馏管装置。 该装置包括第一管,使加热的盐水的进料流通过该第一管流动,第一管由多孔材料构成,该多孔材料既透水又不透水,该管允许水蒸气渗入其中 当加热的盐水流过其中时,其蒸气在蒸气冷却时然后在第一管外冷凝。 该第一管优选由多孔,膨胀聚四氟乙烯构成。 提供大致平行关系并且紧邻第一管的第二管,使冷却水通过该管流动。 冷却水保持在比加热的盐水的温度低的温度,从而导致第二管周围温度的降低,并提供用于蒸馏盐水的增强驱动力。 提供了在其内部容纳第一管和第二管的第三容器管。 该容纳管在其壁中具有多个间隔开的开口,以允许在第一管外部并且在壳体管内部冷凝的淡水流过这些开口,从而从蒸馏管装置向外流动。
