    摘要： The present invention provides a ceramic sintered body excellent in oxidation resistance under high temperatures and markedly superior to the conventional ceramic sintered body in the mechanical strength over a wide temperature range of between room temperature and 1,500.degree. C. The ceramic sintered body of the present invention comprises at least one ceramic crystal grain selected from the group consisting essentially of a monosilicate represented by the general formula RE.sub.2 SiO.sub.5, where RE denotes a IIIa group element including yttrium, and a disilicate represented by the general formula RE.sub.2 Si.sub.2 O.sub.7, where RE denotes a IIIa group element including yttrium, and at least one additional element selected from the group consisting of Al, Cr, Hf, Nb, Zr, Ti, V, Ta, Ca and Mg which is segregated in the boundaries of the ceramic crystal grains in an amount of 0.1 to 15% by weight of the sintered body in terms of the oxide thereof.

    摘要： A brake shoe for an elevator emergency stop has a including a brake body having a braking face and (b) plurality of braking pieces embodied in the braking face side of the brake body to be projected from a braking face. The projection of each of the braking pieces forms a column or a multi-cornered pole having rounded corners. The braking pieces are made of a composite material containing a ceramic base material selected from the group consisting of silicon nitride, silicon carbide and sialon, and particles of at least one ceramic material selected from the group consisting of a carbide, a nitride and a boride. The ceramic particles have a particle size in the range of 10 to 150 .mu.m, and dispersed into the ceramic base material.

    摘要： A method of an electron energy distribution in a plasma region generated by high-frequency power. In the method, a heating probe is inserted into the plasma region and heated by a current flowing into the plasma region. A pulse voltage having a sufficient shorter period than a thermal time constant of the heating probe is applied to the probe, which emits thermions. The number of the thermions emitted sufficiently increases. The plasma vibration frequency of the emitted thermions is sufficiently higher than the frequency of the high-frequency power. The floating potential of the heating probe therefore follows the high frequency potential existing in the plasma. The floating potential difference between a voltage period of the pulse voltage and a no-voltage period is detected, and an the electron energy distribution in the plasma region is thereby determined.
