Abstract: Provided is a method of producing an artificial marble containing amethyst and vermiculite. The artificial marble includes amethyst representing superior performance in terms of a far-infrared emission effect and an antimicrobial property with a fine appearance, and vermiculite serving as an inorganic filler material and representing a superior adiabatic effect with a light weight. The artificial marble has a structure in which the first base layer including amethyst and the second base layer including vermiculite are laminated on each other.

Abstract: An adhesive layer that bonds the back surface of a plate capable of attracting a wafer and the front surface of a cooling plate together that includes a main adhesive portion, which is made of a hardened matter of a fluid adhesive, and an outer peripheral adhesive portion, gas-supply-hole adhesive portions, lift-pin-hole adhesive portions, and terminal-hole adhesive portions made of a double-faced tape. The tape portions bond the outer peripheral edge on the back surface of the plate and the outer peripheral edge on the front surface of the cooling plate together, and the outer peripheral edges of the holes on the back surface of the plate and the outer peripheral edges of these holes on the front surface of the cooling plate together.

Abstract: A method of making a solid oxide fuel cell (SOFC) includes forming a first sublayer of a first electrode on a first side of a planar solid oxide electrolyte and drying the first sublayer of the first electrode. The method also includes forming a second sublayer of the first electrode on the dried first sublayer of the first electrode prior to firing the first sublayer of the first electrode, firing the first and second sublayers of the first electrode during the same first firing step, and forming a second electrode on a second side of the solid oxide electrolyte.

Abstract: An apparatus for welding together thermoplastic hoses comprising two clamping units which in part can be rotated and displaced relative to each other. The two clamping units each have two clamping jaws which comprise through-passages between the clamping jaws in which the hoses can be inserted continuously parallel to each other and squeezed transversely to each other. The apparatus further comprises a heatable blade for severing the hoses and melting the cut edges thereof between the clamping units. An intermediate piece is disposed between the clamping jaws of the clamping units, thereby separating the clamped hoses from each other, and at least one of the two clamping units has inner and outer clamping jaws, wherein the inner clamping jaws are held by the outer clamping jaws and can be adjusted together. In a closed position, the inner clamping jaws and the intermediate piece can be rotated with each other.
