A grain oriented electrical steel sheet includes a base steel sheet, a glass film, and a tension-insulation coating. When a glow discharge emission spectroscopy is conducted from a surface of the glass film toward a depth direction, an analysis starting time Ts, a time T.sup.Al.sub.p at which Al shows a maximum emission intensity, an Al emission intensity F(T.sup.Al.sub.p) at the T.sup.Al.sub.p, a time T.sup.Si.sub.p at which Si shows a maximum emission intensity, and an Al emission intensity F(T.sup.Si.sub.p) at the T.sup.Si.sub.p satisfy 0.05≤F(T.sup.Si.sub.p)/F(T.sup.Al.sub.p)≤0.50 and 2.0≤(T.sup.Al.sub.p−Ts)/(T.sup.Si.sub.p−Ts)≤5.0.

A load structure may include a first honeycomb layer, a second honeycomb layer, and/or an attachment feature. The second honeycomb layer may be connected to the first honeycomb layer. The attachment feature may be connected to at least one of the first honeycomb layer or the second honeycomb layer. A method of manufacturing a load structure may include providing a first honeycomb layer, a second honeycomb layer, and an attachment feature, disposing an adhesive layer onto at least one of the first honeycomb layer or the second honeycomb layer, connecting an attachment feature to the first honeycomb layer or the second honeycomb layer, and/or disposing the first honeycomb layer onto the second honeycomb layer.

A syringe or other vessel having a substrate surface coated by PECVD is provided. The PECVD coating is made by generating plasma from a gaseous reactant comprising an organosilicon precursor and optionally O.sub.2. The lubricity, hydrophobicity and/or barrier properties of the coating are set by setting the ratio of the O.sub.2 to the organosilicon precursor in the gaseous reactant, and/or by setting the electric power used for generating the plasma. In particular, a lubricity coating made by said method is provided. Vessels coated by said method and the use of such vessels protecting a compound or composition contained or received in said coated vessel against mechanical and/or chemical effects of the surface of the uncoated vessel material are also provided.

Methods, apparatus and systems are described that relate to in-situ and in-process assembly of segmented optical component with high accuracy. One example method for assembling an optical component with multiple segments includes positioning the multiple segments to an initial state conforming to an alignment or positioning requirement, measuring positions of the multiple segments at the initial state, initiating a fusing process to fuse the multiple segments of the optical element together, measuring the positions of the multiple segments after commencement of the fusing process, and determining whether a change in the positions of the multiple segments has occurred that causes a deviation from the initial state. Upon a determination that the deviation is not within a tolerance value, the method includes adjusting a position of at least one of the multiple segments to maintain the deviation within the tolerance value.

Procedure for controlling the chemical reaction in multi-layer ceramic decorations, according to interfacial and surface properties, in which the ceramic coating formulation is broken down into two separate compounds: on the one hand, a bottom layer formed by a glaze with part of the necessary oxides to obtain the ceramic effect, applied in the conventional manner over the ceramic substrate, and on the other hand, a top layer formed by an ink with the other necessary part of the oxides, applied by injection over the previous layer. The ceramic product is finished off with a firing process. This procedure has the advantage of regulating the penetration of the oxides of the top layer throughout the profile of the bottom layer, thus achieving an adequate concentration of oxides in the zone nearest to the surface, which permits optimization of the chemical reaction and thus, of the ceramic effect obtained.
