A multi-layered structural element and a method for producing a multi-layered structural element are disclosed. In an embodiment dielectric green sheets, at least one ply containing an auxiliary material which contains at least one copper oxide and layers containing electrode material are provided and arranged alternately one above another. These materials are debindered and sintered. The copper oxide is reduced to form the copper metal and the at least one ply is degraded during debindering and sintering.

Provided is a metal joint (5) including: a Ag—Cu—Zn layer (7); and Cu—Zn layers (6) joined to both surfaces of the Ag—Cu—Zn layer (7), wherein the Ag—Cu—Zn layer (7) has a composition in which a Cu component is 1 atm % or more and 10 atm % or less, a Zn component is 1 atm % or more and 40 atm % or less, and the balance is a Ag component with respect to the total 100 atm %, and wherein the Cu—Zn layers (6) have a composition in which a Zn component is 10 atm % or more and 40 atm % or less and the balance is a Cu component with respect to the total 100 atm %. It is therefore possible to obtain the metal joint (5), which is capable of joining metal base materials to each other without being limited to aluminum-based materials, and also have high mechanical strength.

The laminate of the present disclosure includes multiple glass ceramic layers each containing quartz and a glass that contains SiO.sub.2, B.sub.2O.sub.3, Al.sub.2O.sub.3, and M.sub.2O, where M is an alkali metal. The B concentration of a surface layer portion of the laminate is lower than the B concentration of an inner layer portion of the laminate.

A tin-plated product contains: a substrate 10 of copper or a copper alloy; an underlying layer 12 of nickel which is formed on the surface of the substrate 10; and an outermost layer 14 containing tin, the outermost layer 14 being formed on the surface of the underlying layer 12, the outermost layer 14 being composed of a copper-tin alloy layer 14a of a large number of crystal grains of a copper-tin alloy, tin layers 14b of tin having an average thickness of 0.01 to 0.20 micrometers, and a plurality of copper-nickel-tin alloy layers 14c of a copper-nickel-tin alloy, each of the tin layers 14b being formed in a corresponding one of recessed portions between adjacent two of the crystal grains of the copper-tin alloy on the outermost surface of the copper-tin alloy layer, the copper-nickel-tin alloy layers 14c being arranged on the side of the underlying layer 12 in the copper-tin alloy layer 14a so as to be apart from each other.

A powder carrier, to which a powder layer containing a metal powder is applied, is provided by an automatic powder carrier feed. A first joining partner is pressed onto the powder layer located on the powder carrier so as to bond a powder layer portion to the first joining partner. The first joining partner is raised from the powder carrier together with the powder layer portion bonded to the first joining partner, and the powder layer portion bonded to the first joining partner is arranged between the first and second joining partners. A sintered join is produced between the first and second joining partners by pressing the first and second joining partners against one another such that the powder layer portion makes contact with both the first and second joining partners. The powder layer portion is sintered as the joining partners are being pressed against one another.

A resin composition according to the present invention contains a cyanate compound (A). Further, the resin composition according to the present invention contains a maleimide compound (B) and/or an epoxy resin (C); and primary hexagonal boron nitride particles (D) having an average aspect ratio of 4 to 10.

A laser beam irradiation unit of a laser processing apparatus includes a laser oscillator that oscillates a laser, a Y-axis scanner that executes a high-speed scan with a laser beam emitted from the laser oscillator in a Y-axis direction, an X-axis scanner that executes processing feed of the laser beam emitted from the laser oscillator in an X-axis direction, and a beam condenser. The Y-axis scanner is selected from any of an AOD, a resonant scanner, and a polygon scanner and the X-axis scanner is selected from a galvano scanner and a resonant scanner.

A metal-on-ceramic substrate comprises a ceramic layer, a first metal layer, and a bonding layer joining the ceramic layer to the first metal layer. The bonding layer includes thermoplastic polyimide adhesive that contains thermally conductive particles. This permits the substrate to withstand most common die attach operations, reduces residual stress in the substrate, and simplifies manufacturing processes.

A method of fabrication of a black watch dial, comprising the following steps: providing a substrate (1); deposition of a black coating (2) on said substrate,
wherein said coating (2) comprises carbon nanotubes (21).

A multilayer film including alternately-laminated fluororesin layers and polyimide resin layers, wherein a total number of the fluororesin layers and the polyimide resin layers is five or more, a ratio of the total thickness of the fluororesin layers to the thickness of the whole multilayer film is 50% or more, and at least one of the outermost layers of the multilayer film is a fluororesin layer.
