The invention provides an endoscope having a lens holder, wherein the lens holder includes a body containing a sintered feedstock and machined surfaces. The invention also provides a method of manufacturing the endoscope which includes the steps of molding a metal blank by a MIM process, wherein the metal blank is near net shape and has a sprue, a post, and optionally an outer shell, machining the inner surfaces and then the outer surfaces of the metal blank to form a lens holder, installing a lens in the lens holder, and assembling the lens holder having the lens into the endoscope.

A metal enclosure has a surface region which is coated with cladding material using a laser cladding process. The metal enclosure can form at least a portion of an electronic device housing. All or part of one or more surfaces of the enclosure can be coated with cladding material. The coating of cladding material can be varied at selective regions of the enclosure to provide different structural properties at these regions. The coating of cladding material can be varied at selective regions to provide contrast in cosmetic appearance.

One aspect of the present disclosure includes a turbine vane assembly comprising a vane made from ceramic matrix composite material having an outer wall extending between a leading edge and a trailing edge and between a first end and an opposing second end; an endwall made at least partially from a ceramic matrix composite material configured to engage the first end of the vane; and a retaining region including corresponding bi-cast grooves formed adjacent the first end of the vane and a receiving aperture formed in the endwall; wherein a bond is formed in the retaining region to join the vane and endwall together.

A method of manufacturing a metal separator for a fuel cell includes providing an opening in a metal plate which is to be a part of the metal separator for the fuel cell, integrally molding a sealing member on both sides of an outer peripheral edge of the metal plate to cover the opening, and trimming the sealing member to remove a covering portion of the sealing member that covers the opening and to provide a fluid communication hole, at least one of a fuel gas, an oxidant gas, and a cooling medium being to pass through the fluid communication hole in the fuel cell.

[Task] To provide a method that makes it possible to easily, inexpensively and accurately manufacture a machined part with a simple configuration and an excellent strength. [Means for Solution] In a method for manufacturing a machined part according to the invention, a dislocation is partially introduced (S3), through shot peening, only into a surface layer of a raw material 1 in a region 1a to be machined, graphite is partially deposited (S4), through heating, only in the surface layer of the region 1a to be machined, and then, the surface layer of the region 1a where graphite is deposited is removed, through machining (S5), only by an amount corresponding to a working margin 1c, thereby manufacturing a machined part 1.
