It is an object to prevent deterioration of reflectance of a reflection layer (2; 43) composed of silver or a silver alloy, resulting from heat-caused migration of silver. The reflector (6; 13, 14; 16) for projection type display apparatuses which display image light beams emitted and reflected by a light source (8; 15; 45; 49), modulated for light intensity by a display device (21, 22, 23) and magnified by a projection lens (37), wherein the reflector (6; 13, 14; 16) is provided, on the reflection surface side, with a reflection layer (2; 43) composed at least of silver or a silver alloy, and a layer comprising inorganic particles and a binder composed of a silicon compound; and a light source (8; 15; 45; 49) and image display device (21, 22, 23) which use the reflector (6; 13, 14; 16).
摘要:
The invention proposes electric contact made of a sintered alloy consisting essentially of chromium, copper and tellurium, wherein the sintered alloy is composed of copper matrix and a chromium phase, and wherein particles of a ternary intermetallic compound consisting of chromium, copper and tellurium are present in grains and at grain boundaries of the copper matrix, and at interfaces between the chromium phase and the copper matrix. The disclosure also discloses an electrode for a vacuum interrupter, a vacuum interrupter, a vacuum circuit breaker and a vacuum switch.
