A sailing ship includes a sailing unit, which comprises a hard sail assembly comprising a plurality of hard sail sections of wing-shaped hollow cross section vertically stacked so each, except the lowermost, fits on the one immediately below; a mast assembly comprising a plurality of mast sections of hollow cross section vertically stacked so each, except the lowermost, fits in the one immediately below; connecting members for connecting upper ends of the hard sail sections to upper ends of the mast sections located at the same level; first means for moving each mast section, except the lowermost, toward and away from the one immediately below; and second means for rotating the mast assembly around its longitudinal axis. Overlapping lengths between vertically adjacent mast sections are variably controlled so as to variably control overlapping lengths between vertically adjacent hard sail sections. Thus, the hard sail assembly vertically expands and contracts.

A sailing ship comprises a hard sail assembly. The hard sail assembly comprises a plurality of hard sails of wing-shaped hollow cross section. The hard sails are vertically stacked so that each except the lowermost is received in the one immediately below. The sailing ship further comprises means for driving the hard sails to move each except the lowermost toward and away from the one immediately below, a post extending vertically to support the lowermost hard sail, and second means for rotating the post around its longitudinal axis. Overlapping lengths between vertically adjacent hard sails are variably controlled to make the hard sail assembly expand and contract vertically.

THE DROP-WEIGHT tear test (DWTT) has had a significant positive impact on the fracture properties of linepipe steels. This review summarizes the incidents that started the research leading to the development of the DWTT from I960 to present.The initial driver for the development of the test was an incident that involved 8.3 miles (13.3 km) of brittle fracture during pre-service testing of a natural gas pipeline with gas. The initial goal of the DWTT was to accurately define the ductile-to-brittle transition temperature of pipeline steels to facilitate the specification of transition temperatures below the operating temperature range for linepipe. As the pipeline industry used the low-transition-temperature steels, the need for a measure of the steel toughness emerged to control ductile-fracture propagation arrest leading to examination of the DWTT energy as a substitute for the CharpyV-notch energy which had been identified as the way to define the steel fracture toughness.

THIS PAPER REVIEWS the Charpy V-notch (CVN) impact test and assesses its utility to characterize fracture resistance in applications to modern tough materials in contrast to those encountered prior to the availability of such materials.The origin of the CVN test and its development into a standard for use with metallic materials is discussed, with brief reference also made to application-based standards for use with other engineering materials. Thereafter, the evolution of mechanical and other properties motivated by industry demands is illustrated in regard to strength and toughness.The interpretation of the CVN test in regard to ( 1 ) the force-displacement and compliance response that develops during the test, and (2) factors affecting the energy measured and controlling failure of the CVN specimen, are discussed, including the tup design and the use of sub-size specimens.The utility of CVN testing is illustrated and discussed in the context of pipeline and other applications involving tough steels. Finally, the implications of evolution in material properties is assessed for impact-test practices including ASTM E23 and ISO 148-1, which are specific to the CVN practice, and the drop-weight tear test. It is concluded that where tough materials are involved, alternative testing practices are needed that are better adapted to the specific loading and failure response of the structure of interest.

A method for fabricating a through-silicon via comprises the following steps. Provide a substrate. Form a through silicon hole in the substrate having a diameter of at least 1 m and a depth of at least 5 m. Perform a first chemical vapor deposition process with a first etching/deposition ratio to form a dielectric layer lining the bottom and sidewall of the through silicon hole and the top surface of the substrate. Perform a shape redressing treatment with a second etching/deposition ratio to change the profile of the dielectric layer. Repeat the first chemical vapor deposition process and the shape redressing treatment at least once until the thickness of the dielectric layer reaches to a predetermined value.
