Abstract: The accessory of the present invention comprises 1% to 9% by weight of germanium, 2% to 20% of indium in terms of weight ratio with respect to germanium, and the rest constituted by silver. It can provide an accessory realizing a metallic luster similar to the brightness of platinum and the health-enhancing and curing effect caused by the far-infrared effect at the same time.

Abstract: A thin-film EL element having as a laminated luminescent composite a configuration comprising at least a first layer and a second layer wherein(1) the first layer comprises a compound having a lattice constant, before lamination, larger than that of a compound constituting the second layer, and contains manganese as a luminescent center impurity,(2) the difference between the lattice constant, before lamination, of the compound of the first layer and the compound constituting the second layer is 5% or more, and(3) the peak value of the emission spectrum of the laminated luminescent composite rests on 590 nm or more, whereby the thin-film EL element can provide red light having high color purity.

Abstract: An vacuum evaporating apparatus for depositing thin films on a substrate comprises a vacuum tank, a hot-wall furnace for heating and evaporating a material to be evaporated, an auxiliary vacuuming means connected to the vacuum tank through a gate valve, a substrate exchanging mechanism for an evaporated substrate with a new substrate through the auxiliary vacuuming device, and a substrate transferring unit generally of a turn table located to be rotatable above the hot-wall furnace. The hot-wall furnaces are disposed in standing state in the vacuum tank, each of hot-wall furnaces being provided with a plurality of crucibles coaxial in a vertical direction in which the evaporation source materials are accommodated, heaters independently provided for the respective crucibles, and thermocouples connected to the respective heaters to independently control the temperatures of the respective crucibles.

Abstract: Two or more crucibles containing different source materials to be vaporized are arranged concentrically, with their mouths open to a vapor chamber defined by an open top envelope within a vacuum housing. The vacuum housing is evacuated while the vapor chamber is held open. Then, with the vapor chamber closed, heat is applied to the crucibles as well as to the envelope to evaporate the source compounds within the crucibles. A substrate is held against the open top of the vapor chamber when the vapor pressure therein rises to a predetermined degree, thereby causing deposition of the vaporized source materials onto the substrate in the form of a crystalline compound film. As required, an impurity evaporator may also be provided within the vacuum housing for doping the compound film. The substrate having the crystalline compound film grown thereon may be moved from over the vapor chamber to a position over the impurity evaporator.
