    摘要： The thermoplastic polyurethane molding of the present invention is obtained by melting, molding, cooling and solidifying, subsequently heating to a temperature T1 (specifically, 180 to 190° C) that is not more than flow starting temperature Tm and not less than glass transition point Tg and cooling down quickly to a temperature T2 (Tm>T1>T2>Tg, specifically, 160 to 165° C.). In dynamic viscoelasticity measurement, the difference between the temperature at which LogE′ turns 4.5 MPa and the peak temperature of tan δ is 190 to 225° C.

    摘要： A mandrel assembly is provided for insertion into a hollow tube to support the interior walls of the tube during bending of the tube in a tube bending apparatus. The mandrel assembly includes at least one mandrel segment that is adapted for positioning within the tube and has an exterior support surface for supporting the interior walls of the tube during bending. The mandrel segment is anchored at a fixed axial location within the tube by an anchoring device that is radially expandable and retractable between an expanded condition in which an anchor shoe is engaged with the interior wall of the tube and a retracted condition in which the anchor shoe is loose within the tube. A mandrel support rod is attached to the anchoring device for inserting and withdrawing the anchoring device into the tube when the anchor shoe is retracted.

    摘要： The present invention discloses a method of SiGe epitaxy with high germanium concentration, a germanium concentration can be increased by reducing the percentage of silane and germane during introduction silane and germane. With the same flow of germanium source, the germanium concentration is significantly increased as the germane flow is reduced, therefore a defect-free SiGe epitaxial film with a germanium atomic percentage of 25˜35% can be obtained. The present invention can balance epitaxial growth rate and germanium doping concentration by using existing equipments to obtain a high germanium concentration, and the epitaxial growth rate is only reduced a little, which can keep the SiGe epitaxial layer having no defect to meet the requirements of devices and can maintain sufficient throughput.

    摘要翻译： 本发明公开了一种具有高锗浓度的SiGe外延法，可以通过在引入硅烷和锗烷中降低硅烷和锗烷的百分比来提高锗浓度。 通过锗源的相同流动，锗的浓度随着锗含量的降低而显着增加，因此可以获得锗原子百分比为25〜35％的无缺陷SiGe外延膜。 本发明可以通过使用现有的设备来平衡外延生长速率和锗掺杂浓度以获得高的锗浓度，并且外延生长速率仅稍微降低，这可以保持SiGe外延层没有缺陷以满足器件的要求 并可以保持足够的吞吐量。

    摘要： The invention provides a hydroforming apparatus for forming a length of tube. A hydroforming press includes an upper platen and a lower plate. A first die set is provided for forming a first lengthwise portion of the tube and a second die set provided adjacent the first die set which forms a second lengthwise portion of the tube. A first pivot acts between a first and second upper die so that the second upper die can be pivotally adjusted on the upper platen relative to the first upper die. A second pivot acts between a first and second lower die so that the second lower die can be pivotally adjusted on the lower platen relative to the first lower die. A die insert is provided having an upper die insert and a lower die insert that define upper and lower insert cavities that connect together the first and second cavity portions of the upper die set and the lower die set. This die insert is removably mounted as needed to accommodate the pivotal adjustment between the first and second die sets.
