Title: Cathode for electronic tube and its manufacture
Inventor: KI GANSHIYOU
IPC: H01J1/14
Filed: 1990-09-07
Abstract: PURPOSE: To improve dispersed state of a reducing agent contained is thermionic emission material and to generally improve thermionic emission characteristics by a method, wherein a fourth material containing the thermionic emission material is made of one of scandium nitrate, rare metal nitrate and indium nitrate. CONSTITUTION: A thermionic emission material layer 3 comprising ternary alkaline earth metal carbonate composed of barium, strontium and calcium is formed on the surface of a base matal 2, and is decomposed thermally to form an oxide thermionic emission material layer. This thermionic emission material contains at least one of scandium nitrate, rare metal nitrate and indium nitrate as a fourth material. A negative electrode for electron tube exhibits high thermionic emission characteristic, because the fourth material such as a rare earth and scandium nitrate, and rare earth nitrate or indium nitrate is thermally decomposed and uniformly dispersed as an oxide. This significantly improves the thermionic emission characteristic and also lengthens the lifetime of the negative electrode. Thus, the highly reliable negative electrode for electron tube can be obtained.

Title: Continuous casting method for hollow ingot
Inventor: ITOYAMA SEIJI
IPC: B22D11/00
Filed: 1985-10-25
Abstract: PURPOSE:To prevent the cracking of a core by the thermal fatigue of the core in the stage of continuously casting a hollow ingot and the danger of steam explosion, etc. of a cooling medium by passing a low melting metal having the b.p. higher than the solidifying temp. of the metal to be cast as a core cooling medium into the core. CONSTITUTION:The core 7 is cooled while the above-mentioned low melting molten metal 12 which is the cooling medium for the core 7 is made to overflow from the top end of a supply pipe 13 and is passed between the inside wall of a cooling passage 11 and the pipe 13. The molten metal 12 absorbs the heat of the molten metal 5 to be cast and heats up during this time, but the molten metal is cooled by a heat exchanger 17 in the circulation path on the outside of the core 7 down to the temp. to the extent at which said metal does not solidify. Such molten metal is again supplied 14 for cooling of the core 7. A pure metal or alloy, for example, Pb (alloy) or the like having about 100-400 deg.C m.p. is usually used for the molten metal 12. As a result, the core is cooled without using water which is the cause for the danger of steam explosion as the core cooling medium, by which the continuous casting of the hollow ingot 20 is executed with the much higher safety than heretofore.
