A process for producing a fluid transfer surface, which process comprises: providing a titanium or titanium alloy surface; subjecting the titanium or titanium alloy surface to surface hardening by interstitial element absorption to provide a hardened surface; and, if required engraving the hardened surface to provide a desired surface topography.

After a free-form surface is machined on an elongated material 1 with a projection 3 and a blade root 4 held, the holding of the projection 3 is released to release strain generated during machining. Upon release of the holding, the entire elongated material 1 deforms, and the projection 3 moves from a holding position A to a strain-released position B. A re-holding position C obtained by correcting the position B by the deformation amount of the elongated material 1 due to the weight of the elongated material 1 is determined, and the projection 3 is held again at the re-holding position C for further machining the free-form surface on the elongated material 1.

The invention relates to a method for machining the interior of a brake caliper (1) of a disc brake, on which are formed: a first saddle portion to the one side of the brake disc of the disc brake, a second saddle portion to the other side of the brake disc, and a bridge section connecting the saddle portions and providing a free space for at least a part of the brake disc. At least one of the saddle portions is provided with a hollow space (7) for receiving a brake application device, wherein said hollow space comprises a mounting opening (4) towards the free space and extends in the opposite direction until a saddle rear wall (18). At least one support surface for the forces acting during the brake application is formed on the inner side of the saddle rear wall. The machining of the support surface (20) is carried out from the direction of the free space and, for this purpose, a tool (55) is brought from outside of the brake caliper (1) into the hollow space. In order to provide a method for machining the interior of a brake caliper of a disc brake, which allows a high-precision machining of the support surfaces inside the brake caliper even in the case of the narrow space conditions which are typical for the machining of a single-piece brake caliper, the tool (55) is guided into the cavity through another opening (25) than the mounting opening (4).

Embodiments provide a helical layer structure including: a helical core member which is formed of a flexible, lengthy, flat plate-like core member and which is formed of a steel plate made of a metal material, such as iron; and a polymeric coating layer which is formed of a polymeric material such as a thermosetting elastic material or a thermoplastic elastic material, and which coats the helical core member. The manufacturing method of the helical layer structure includes: a feeding step of feeding a core member having flexibility; a supply step of supplying the polymeric material having fluidity; a coating step of coating the core member with the polymeric material; a cooling step of cooling a coated intermediate which is coated with the polymeric material; and a helix formation step of helically twisting the coated intermediate to form the helical layer structure.

A putter-type golf club head and method of manufacturing said golf club are herein disclosed. The putter has a body, a face surface, a rear surface, a sole surface, a crown surface, and a heel surface. To reduce the reflective glare off the crown surface and to improve the ease of alignment, the putter includes various curved boundaries between surfaces of the club head. Multiple sections of the crown connect with the heel surface through curved transition regions, which reflect the light differently than the crown surface and thus serve as alignment aids.

Systems and methods are provided for securement of parts. One embodiment is a method for securing a part during fabrication. The method includes forming an interference fit between a pin and a wall defining a hole, supporting a weight of the part with the interference fit, and rotating the part around an axis of the part while the weight of the part is supported.

A surgical instrument assembly is disclosed. The surgical instrument assembly can include an instrument attachment interface, a shaft, a firing member, an articulation joint, and an end effector including a first jaw, a second jaw, an anvil, and a replaceable staple cartridge comprising a proximal end, a distal end, a slot, at least two rows of staple cavities, and a plurality of staples stored within the staple cavities. The staples can be deployed by the firing member. Each staple can include, one, a staple leg comprising planar surfaces and, two, a staple base, wherein the staple leg extends from the staple base, wherein the staple base comprises planar surfaces and a camming surface distally offset from the staple leg and configured to be directly engaged by the firing member, and wherein the staple leg is configured to be formed over the camming surface.

A head for a ball striking device includes a bracing member connected to an upper sole surface located on the sole of the body opposite the bottom sole surface. The bracing member includes a first end connected to a first point on the upper sole surface, a second end connected to a second point on the upper sole surface spaced from the first point, and a bridge portion extending between the first and second ends. The bridge portion extends upward from the upper sole surface and is spaced from the upper sole surface. The bridge portion may be formed by one or more trusses, and may define a generally triangular shape in one embodiment. The first and second ends may be connected to the upper sole surface using a variety of techniques, e.g., welding or other integral joining technique, integral forming, adhesive or other bonding material, or other technique.

The present disclosure provides three-dimensional structures and related methods. The three-dimensional structures may define patterns of positive and negative spaces on opposing surfaces that combine to form the three-dimensional structures. The negative spaces of the patterns may intersect to form apertures through the three-dimensional structures, which may define linear or non-linear paths therethrough. The apertures may be configured to provide desirable characteristics with respect to light, sound, and fluid travel therethrough. Further, the three-dimensional structures may be configured to define desired stiffness, weight, and/or flexibility. The three-dimensional structures may be employed in embodiments including heat sinks, housings, speaker or vent covers, springs, etc.

Methods, system, devices, processes and techniques are disclosed for manufacturing orthopedic implants utilizing blanks and/or fixtures.
