摘要： PURPOSE:To improve the durability in the addition of the heat cycle having the large temperature variation by forming a ceramic structure part which is accommodated in a housing and applied with the high temperature heat, by a sintered body having the specific composition and bulk density. CONSTITUTION:As for a catalyst ignitor 9 for igniting the after burner of an aircraft engine, a disc-shaped ceramic structure part (disc) 9c is accommodated in a cover 9b arranged in a housing 9a. Further, in an outside sleeve 9g arranged in the housing 9a, a ceramic structure part (body) 9h having an L-shaped rotary body shape is accommodated. In this case, each of ceramics structure parts 9c and 9h is formed from a sintered body containing 1.5-6wt.% BN in 93-96wt.% Si3N4. Further, the bulk density of the sintered body is set in a range of 1.95-2.30. Accordingly, the durability in the addition of the heat cycle having the large temperature variation can be improved.

摘要： PURPOSE:To improve a chipping characteristic and wear resistance and to continuously cast particularly a high-Cr steel stably for a long period of time by adjusting the dynamic modulus of elasticity, pore size and heat conductivity of the steel to specific values. CONSTITUTION:Raw materials including AlN, BN, Al2O3, Si, SiO2 and Si3O4 having 5mum average particle size are compounded at required ratios and are thoroughly kneaded. After the kneaded material is molded to a suitable molding means, the molding is sintered for about 1-10hr at 1,400-1,800 deg.C in a non- oxidizing atmosphere of argon, gaseous nitrogen, etc. to obtain the molding having kgf/cm , more preferably kgf/cm dynamic modulus of elasticity,

摘要： PROBLEM TO BE SOLVED: To enable pressure in a wafer case during air transportation to be restored promptly after landing by providing a bag for packaging a wafer case with semiconductor wafers housed therein, and setting in a specific range the ratio of a value in which the volume of semiconductor wafers is subtracted from the content volume of the bag and the content volume of the wafer case. SOLUTION: The wafer case 3 for a semiconductor wafer packaging body 1 is comprised of a case main body 5 and a lid body 7. A bag 4 for packaging this wafer case 3 is provided with an opening for putting in and out the wafer case 3 at its one side. In this case, regarding the size of the wafer case 3 and the bag 4, the ratio of a value in which the volume of the semiconductor is subtracted from the content volume of the bag 4 and the content volume of the wafer case 3 is set to be in a range of 1.03-1.18. By this structure, even in the case where if the atmosphere in the airplane lowers during air- transportation and thereby air in the wafer case 3 comes out of the bag 4, the pressure in the wafer case 3 is maintained on the order of 0.9 atm, so that the pressure in the water case can be restored promptly to the atmosphere after landing.

SOLUTION: Hydraulic alumina is added as a binder by 3-15 wt.% to a granular aluminuous refractory aggregate consisting mainly of alumina. Transistion luminous such as ρ-alumina, χ-alumina, η-alumina, γ-alumina or θ-alumina may be used as the hydraulic alumina. Granular silicon carbide of a 0.1-0.5 mm particle diameter may further be added by 4-20 wt.%.
