Title: Silicon nitride-based sintered body
Inventor: KOSAKA SHOJI
IPC: C04B35/584
Filed: 1987-09-30
Abstract: PURPOSE:To improve the bending strength and toughness of the title sintered body by dispersing a metal or its compd. in the composition wherein the molar ratio of the SiO2 to the oxide of a group IIIa element is specified in an Si3N4- SiO2-oxide of a group IIIa element based sintered body. CONSTITUTION:The metallic Nb, Ta, Ti, W, and Mo or their compds. are dispersed in the silicon nitride matrix wherein the molar ratio of the SiO2 to the oxide of a group IIIa element is controlled to >=1 in the three-component silicon nitride-based sintered body (Si3N4-SiO2-oxide of a group IIIa element). Since the metal to be added is hardly melted and deformed at high temp. and has a relatively low thermal expansion coefficient, the bending strength is not sufficiently increased only by adding the metals or their compds. to the three- component body. However, the toughness can be remarkably improved without deteriorating the bending strength by applying the metals or their compds. to the composition wherein the molar ratio of the SiO2 to the oxide of a group IIIa element is controlled to >=1, and sintering the composition.

Filed: 1992-09-18
Abstract: PURPOSE:To evaluate weldability of the damping steel plate with high accuracy by specifying the relation between the voltage and a current of a first cycle of spot welding. CONSTITUTION:Effective values of the voltage between electrodes and an applied current value of the first cycle of spot welding are measured for different voltages or current values, these are plotted for rectangular coordinates, regression equation V1=c1.I1+b1 is obtained and a spot welding value is controlled be values of b1 and c1 wherein the values of b1 and c1 are regulated in the range of 0.3-0.5. Further, a condition of constants c2<c1 of a second cycle is desirable. This shows that a current path in the beginning of spot welding is unstable according to a state of the steel plate surface and welding resistance is high. Further, the second cycle has lower welding resistance than the first cycle. Since (c) value gives a minimum resistance value and the current of spot welding flows, the current path is considered to be subject to restriction.
