摘要： A breathable salt core is provided that is placed in a cavity of a casting mold in order to mold a hollow part of a cast product and that is dissolved and removed after casting, the breathable salt core being formed by powder molding innumerable salt particles into a predetermined shape corresponding to the hollow part, wherein a gap that can retain a gas remaining in the cavity in a casting process is formed between the innumerable salt particles that have been powder molded. The breathable salt core thus manufactured assures that residual gas within the cavity pushed by the molten metal to enter the gap formed between salt particles of the salt core, thereby avoiding any incomplete filling of the molten metal, and which can be formed with a simple production process at a low cost.

摘要： A surgical retractor for illuminating a surgical field includes an ergonomic handle, a retractor blade coupled with the handle, a quick release mechanism, and an illuminator blade. The retractor blade is adapted to engage and retract tissue, and the quick release mechanism is adapted to couple the handle with the retractor blade. The illuminator blade acts as a waveguide to transmit light by total internal reflection. Light is extracted from the illuminator to illuminate the surgical field. The retractor blade is releasable from the handle without requiring uncoupling of the illuminator blade from the handle and also without requiring optical uncoupling of the illuminator blade from a light source. The retractor may also be adapted to evacuate smoke from the surgical field.

摘要： Provided is a multicore. The multicore includes a first core, being made of a water-insoluble material, having a hollow formed in the first core and, having an opening formed at both ends of the first core and connected to the hollow, a second core, being made of a water-soluble material and disposed inside the hollow, and a coating layer, being configured to surround the first core to prevent at least a portion of the first core and the second core from being exposed to an outside. Further, the first core includes a plurality of spaces to allow a fluid supplied to an interior of the first core to flow toward the second core.

摘要： The present invention comprises: a blank forming step in which a casing blank (70) is formed by die-casting, the casing blank (70) having a first cylindrical section (41), a second cylindrical section (42), and an annular section (44) which includes a recess (71) recessed toward one side in an axial direction (O) from a first surface (44a) facing the other side in the axial direction (O); and a cutting step in which the inner peripheral surface (42a) of the second cylindrical section (42) and a second surface (44b) of the annular section (44), the second surface (44b) facing the one side in the axial direction (O), are cut to connect the recess (71) to a compression section containing space (42A) within the second cylindrical section (42), thereby forming a flow passage. In the blank forming step, the casing blank (70) is formed such that a part of a side surface (71a) of the recess (71) is disposed radially outside the inner peripheral surface (42a) of the second cylindrical section (42).

摘要： Disclosed is a cooled airfoil having a hub end and tip, an airfoil height being defined between the hub end and the tip. The airfoil has a leading edge, trailing edge, suction side and pressure side. The airfoil has a first airfoil height section adjacent the hub end and extending towards the tip, wherein, in a meridional view, the leading edge and trailing edge are straight along the first airfoil height section. The airfoil has a second airfoil height section adjacent the tip and extending towards the hub end, wherein, in a meridional view, the airfoil is concavely shaped at the leading edge and is convexly shaped at the trailing edge along the second airfoil height section. At least one cooling channel has a length principally extending along the airfoil height, extends straight in a first cooling channel length section, and is bent in a second cooling channel length section.

摘要： A cast component having reduced cross flow linking cavities and method of casting may include a body. The body may define a plurality of internal flow channels. The plurality of internal flow channels may include a first internal flow channel and a second internal flow channel. The cast component may also include a plurality of linking cavities obstructing unintended fluid communication between the first internal flow channel and the second internal flow channel through the plurality of linking cavities.
