A cooking appliance includes a chamber surface that defines a cavity including a cooking chamber, a door that is configured to open and close the cavity and has a door surface configured to face the cavity, a heat source configured to supply heat to the cavity, and a coating layer disposed on the chamber surface or the door surface. The coating layer includes an enamel composition of materials including 30 to 45 wt % of phosphorus pentoxide (P.sub.2O.sub.5), 5 to 20 wt % of silicon dioxide (SiO.sub.2), 15 to 30 wt % of aluminum oxide (Al.sub.2O.sub.3), 10 to 20 wt % of zirconium dioxide (ZrO.sub.2), 5 to 20 wt % of at least one of lithium oxide (Li.sub.2O), sodium oxide (N.sub.2O), or potassium oxide (K.sub.2O), 5 to 15 wt % of boron trioxide (B.sub.2O.sub.3), and10 to 25 wt % of vanadium pentoxide (V.sub.2O.sub.5).

A wired and detachable, moveable, dis-assemble, re-assemble USB or Wireless charging-unit(s) which has minimum feet DC power delivery wire that is manual to coil, wrap within unit's own space for wire-arrangement, said each wired and detachable unit(s) cover broad area and people can chare external product(s) at any location within said area; wherein said unit(s) assembly with electric product which is at least one (1) desk, floor, wall-mounted item, light, (2) power strip, (3) selfie LED light has built-in or added-on image capture device(s).

A functional element according to an embodiment of the present disclosure includes: a first substrate; a second substrate disposed to face the first substrate; and a buffer layer provided between the first substrate and the second substrate. The buffer layer has, in a layer thereof, a distribution of concentration of a metallic element. The distribution changes in a film thickness direction.

A nerve stimulator and a manufacturing method thereof. The nerve stimulator includes a glass substrate, and a plurality of metal pins provided on the substrate, wherein the metal pins form stimulation portions on one side of the substrate, and the density of the metal pins is greater than 15 Pin/mm.sup.2. The stimulation portions in the present nerve stimulator have a high density and a good stimulation effect. The processing method thereof is to cut out a high-density metal pin array first by using a metal underlayer, then the manufacturing method overcomes the deficiency in the prior art that it is rather difficult to manufacture a high density of nerve stimulation electrodes by using other substrates such as ceramics and the like.

The invention relates to an anodic bonding method for bonding two elements with an intermediate layer. The invention especially, but not exclusively, relates to an anodic bonding method for between a metallic element and a heterogeneous element, for example a glass, artificial sapphire or ceramic element. The specificity and aim of the present invention is to produce an assembly that is gas-tight and fluid-tight, solderless, brazing- or welder-free and without organic compound (glue). The present method has multiple industrial applications, including making it possible to attach a watch-glass, typically made of mineral glass, sapphire or transparent or translucent ceramics, to a bezel or case middle of a watch case using the anodic bonding technique.
