Title: Method for joining zro2 ceramics
Inventor: HIRAI SHOZO
IPC: C04B37/00
Filed: 1992-08-14
Abstract: PURPOSE:To improve joinability by forming metallic films of Pt in the joint parts of respective ceramics, then firing the ceramics at a specific temp. to tightly adhere these metallic films to the joint surfaces of the ceramics and brazing the tightly adhered metallic films to each other by an Au brazing filler metal. CONSTITUTION:Powder consisting essentially of the Pt is made into paste and this paste is applied on the joint surfaces of the ceramic pipes 1.1 and 1.2 consisting essentially of ZrO2 to form the metallic films 2. The ceramic pipes 1.1 and 1.2 formed with the metallic films 2 are then set in a furnace and are heated to 1400 deg.C to the m.p. (1760 deg.C) of the Pt in the atm. to increase the density of the metallic films 2 and to melt a part of the glassy material forming the grain boundaries of the ceramics to cause the reaction thereof with the Pt, by which the adhesive power of the ceramics and the metallic films 2 is improved. The parts formed with the metallic films 2 of the ceramic pipes 1.1 and 1.2 are fitted to each other and the brazing filler metal 3 consisting essentially of the Au is heated to the m.p. thereof or above and is melted into the fitting parts, by which the surfaces of the metallic films 2 are wetted and the spacing therebetween is filled. The ceramic pipes are then cooled down to room temp. to complete the joining.

Abstract: PROBLEM TO BE SOLVED: To easily shorten the execution time of a test program with a simple configuration, by a method wherein the test condition of a second test item onward is compared with the test condition of a previous test item, and only different test conditions are set at an input/output means. SOLUTION: By a test-condition setting means 20 in an apparatus 10, a test-program analytical part 3 analyzes a test program in every test process so as to obtain its analyzed result. A test-condition storage and control part 4 stores a test condition in a memory 2.

As a result, a test-condition setting and control part 7 supplies only different test conditions to a hardware part 1 in a testing apparatus. Consequently, only a changd test condition is set at the hardware part 1, and a test setting instruction in the test program can be reduced sharply.
