Provided is a short stroke type extrusion press which is capable of increasing a container strip force, improving energy efficiency, and saving space by reducing apparatus length. A main cylinder housing (4) of the extrusion press comprises a transfer medium (10) which advances or retreats an extrusion stem (13) in an extrusion axis direction, and a transfer medium (16) which advances or retreats a container (14) in the extrusion axis direction. A container pushing medium (21) is disposed at an end platen (1) disposed opposite the main cylinder housing (4) and makes it possible for at least four different transfer motions to be carried out independently or in collaboration with the container transfer medium in the direction in which the container (14) separates from a die (9).

The invention relates to a plug-in steel wire rope connector which comprises a casting body and a steel wire rope. The end of the steel wire rope is inserted into an opening of the casting body and welded together. The casting body is a closed type casting body with an opening formed in the end. An inner cavity of the opening end of the casting body is divided into an inverted-cone cavity body and a filling shrinkage cavity body. The inverted-cone cavity body is a cone opening gradually shrunk from inside to outside. The filling shrinkage cavity body is formed in the outer end of the inverted-cone cavity body. The inner diameter of the filling shrinkage cavity body is larger than the inner diameter of the inverted-cone cavity body at the transition portion of the filling shrinkage cavity body and the inverted-cone cavity body. According to the plug-in steel wire rope connector, as the casting body is arranged in a closed form with one end open, the filling shrinkage cavity body is designed in the end, before the end of the steel wire rope is inserted into the casting body, brazing filler metal is placed into the casting body, and the brazing filler metal in the filling shrinkage cavity body is shrunk due to the fact that liquid brazing filler metal in the inverted-cone cavity body is cooled and turned into a solid, so that most brazing filler metal flows into the inverted-cone cavity body, and a welding seam structure basically flawless in the inverted-cone cavity body is formed.

A composite panel includes a honeycomb core sandwiched by a pair of skins that are attached directly to the core with no separate adhesive layer. The skins are impregnated with a resin material that is unevenly distributed between first and second surfaces, and direct contact is established between the surfaces with the greater resin distribution and the core, reducing weight and eliminating the manufacturing step of incorporating an adhesive layer therebetween.

In order that the pitch angle of a wind turbine blade can be changed using a simple, lightweight, low cost, and highly durable structure without impairing the strength of each portion such as a rotor hub, the present pitch drive device (15) is characterized in comprising: a cylinder support section (27) provided to the rotor hub (10) and having a support point (31) located on the side of the cylinder support section (27) which is opposite the front end surface (22)(non-supported end section) of the rotor hub (10); an eccentric connection point (34) provided at an eccentric position on the root-side end surface (11b) of the wind turbine blade (11); and a cylinder (35) disposed so as to penetrate through the non-supported end section (22) of the rotor hub (10) and configured in such a manner that a connection section (38) provided to the portion of the cylinder (35) which protrudes further outward than the non-supported end section (22) is rotatably connected to the support point (31) through a spherical surface joint (39) and in such a manner that a connection section (40) located on the inner side of the non-supported end section (22) is rotatably connected to the eccentric connection point (34) through a spherical surface joint (41).

The invention describes an LED lighting unit (1) comprising a container (12) with a number of partially reflective side walls (120); a light exit opening (11) defined by the side walls (120); and a number of light-emitting diodes (10) arranged in the container (12) to emit light (L10) of a first colour (CLED) through the light exit opening (11) during an on-state of the lighting unit (1). The LEDlighting unit is characterized in that the material properties of the partially reflective container side walls (120) are chosen to impart a second non-white colour (CPG, CPY, CPB) to the container side walls (120), and to absorb light in at least one specific region (S40, S41, S60, S70) of the visible spectrum such that light (L120) of the non-white second colour (CPG, CPY, CPB) exits the lighting unit (1) through the light exit opening (11) during an off-state of the lighting unit (1). The invention further describes a method of manufacturing such an LED lighting unit (1).

The invention relates to a method for forming a composite material joint by adopting a multi-direction composite material joint RTM mould. According to the method, a multi-direction joint fiber prefabricated body is arranged in an RTM mould designed with a prefabricated hole core mould; assembling and sealing detection of the mould are completed; vacuumizing is carried out, and meanwhile preheating resin is injected in a pressurizing mode; after resin mould filling is completed, a resin injection opening and a resin outlet are sealed, the mould is wholly placed in an oven to be heated, and the fiber prefabricated body is fully soaked with the resin in the mould along with rising of the temperature; chemical reaction happens under the high-temperature action, and curing and forming are completed. Precise forming of the carbon fiber reinforced resin-based composite material multi-direction joint and precise forming of the mounting hole position of an embedded part of the joint can be achieved, through structural design of the mould, a prefabricated hole of the multi-direction joint can be directly formed, secondary machining is not needed, it is ensured that fibers in the opening are continuous, production and machining defects are avoided, and therefore the mechanical property of the product is ensured.
