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.

The invention aims at providing a vacuum circuit-breaker, a vacuum bulb used therein and electrodes for the vacuum bulb, which can reduce the manufacturing cost while being of high performance and compact in size. The invention resides in a vacuum circuit-breaker, a vacuum bulb and electrodes for the vacuum bulb, which are characterized in that fixed and movable electrodes (30a, 30b) each comprise arc electrodes (1), whose entire surfaces, mutually facing each other, are made of an alloy containing a refractory metal and a highly conductive metal, and electrode rods (4) of a highly conductive metal supporting the respective arc electrodes, and that each arc electrode and the mating electrode rod are integrally formed by means of solid-phase diffusion bonding.

Interference film filters and optical waveguides with low loss of light, including a laminate deposition-formed on a substrate (1,30) by alternate sputtered lamination of a first film (2,4,10) of amorphous Si x C y O z (x:y:z = 1:0.6-1:0-0.5) having refractive index up to 3.4 and an extinction coefficient below 0.1 and a second thin film (3,5,20) of amorphous Si x O y C z (x:y:z = 1:1.8-2:0-0.5) having a low refractive index in comparison with that of the first thin film. The two film types may be sputtered from a single sintered SiC target by varying oxygen content of a sputter gas mixture.
