Method for fabricating a three-dimensional object by successive consolidation, layer by layer, of selected regions of a layer of powder, consolidated regions corresponding to successive sections of the three-dimensional object, comprising in order:

• a—deposit layer of powder onto a support;
• b—fuse the layer of powder by a first laser energy source so as to obtain a fused layer corresponding to the section of the object and exhibiting a first state of its mechanical properties,
• c—heat at least a part of the fused layer by a second electron beam energy source to a temperature which follows a controlled variation over time so as to modify the first state of the fused layer and to obtain a consolidated layer with improved mechanical properties,
• d—repeat the preceding steps until several superposed consolidated layers are formed with improved properties forming the object.

Method of manufacturing a heat exchanger from a formable laminate (1, 11, 105) of a metal layer and a heat-seal layer whereby the laminate is sealed under heat and pressure to itself or to another similar laminate to form a flow channel for a heat exchange medium. Preferably the heat exchanger includes a series of fins (3, 106, 107) formed on the laminate (1, 11, 105) to increase heat transfer and may also include a water retaining layer (204).

There is provided a vehicle skeleton member including a composite material of a thermoplastic resin and a carbon fiber, wherein the composite material is a unidirectional carbon-fiber composite material (A) that a form of the carbon fiber in the composite material is a continuous fiber aligned in one direction and/or a random carbon-fiber composite material (B) that a form of the carbon fiber in the composite material is a discontinuous fiber arranged two-dimensionally randomly.

A method of manufacturing a medical implant comprising a radiopaque marker is described. The method comprises manufacturing a medical implant using stereolithography, wherein the medical implant has an external surface that delimits an opening to a channel. A curable mixture of a biocompatible polymer and a radiopaque material is then inserted into the channel while in a liquid state and cured in the channel so that it solidifies in the channel.

The combination of an implant manufactured by stereolithography and a radiopaque marker which is inserted into the channel in a liquid state enables complex internal structures to be formed in the implant for the radiopaque marker and for the marker to take on those complex forms more easily. This allows a better visualisation of the marker under X-Ray or other medical imaging technique.

The invention discloses a manufacturing method of a steel hot-stamped product with an aluminum or aluminum alloy plating layer. The manufacturing method comprises the following steps: 1) blanking: a steel plate with the aluminum or aluminum alloy plating layer is machined to a part blank with a needed shape by a blanking or laser cutting method; and the thickness of the steel plate with the plating layer is not more than 2.8 mm; 2) blank heat treatment: the blank is put in a heating furnace for heating and insulation; the temperature of the heating furnace is 900-950 DEG C; the atmosphere in the heating furnace guarantees the oxygen content to be more than 15%; and the total stop time of the blank in the heating furnace is 2.5-10 minutes; 3) blank transmission: the heated blank is quickly conveyed into a mold for punching; the conveying time is 4-12 seconds; and the temperature of the blank before punching is 680-750 DEG C; and 4) blank hot stamping: the heated blank is directly punched in the mold; the mold is cooled in the punching process; and the surface temperature of the mold before punching is lower than 100 DEG C.

A process for joining silicon-containing ceramic articles, and particularly ceramic articles and CMC articles that contain both silicon carbide and free silicon. The process entails providing a reactive metal-containing braze material between the articles, and then heating the braze material and the articles to react the reactive metal with the silicon within the articles to form a brazement containing a silicide phase of the reactive metal. The brazement and articles are then cooled to produce a component comprising the two articles and the silicide phase-containing brazement. The process is preferably carried out at temperatures below that which would thermally degrade constituents of the articles, and more preferably below the melting point of silicon.

The present invention provides a shaping sheet that includes a base material having at least an ink layer provided on the whole surface thereof and a surface shaping layer that is present on the ink layer, contacts the ink layer, and covers the whole surface of the ink layer, in which the surface shaping layer is a crosslinked and cured product of a curable resin composition and the surface shaping layer has a concavoconvex pattern on a surface thereof. There can be obtained: a shaping sheet that has a fine concavoconvex pattern, allows elaborated shaping with a high-grade feeling, and has excellent releasability; a shaping sheet having excellent design properties and releasability that can readily control a lustrous portion and a matted portion; and further a shaping sheet whose surface is free of contamination by impurities separated out of the base material even when it is repeatedly used.

The present invention provides a composition comprising a liquid crystalline polyester, a plate-like filler and a carbon black having a number average particle size of more than 20 nm and 45 nm or less. The composition is less likely to cause blister even at a high temperature.

The present invention provides a method of joining a sheet metal part to a metal tube to form an assembly. In an overlapping configuration, the parts are held together under a clamping force while a self-piercing rivet is driven through the assembly by a welding electrode. The rivet pierces and passes through the sheet metal part and then through at least substantial portion of the metal tube to thereby form a mechanical interlock. An electrical current is then applied to this mechanical retention to melt a portion of the rivet as well as a portion of the metal surrounding the joining region. The flow of electrical current is then stopped after several welding cycles where the now melted material is allowed to solidify upon cooling, thereby forming a weld.

An electrical connector can be fitted with either an electric wire cover (40) or a component installation cover (30), the choice of cover corresponding to the presence or absence of an electrical component (39) in the corresponding connector housing. The electric wire cover (40) or the component installation cover (30) are installed detachably and, as a result, the relatively expensive connector housing (10) is provided with shared components which can be adapted to the intended use.
