Title: Productionof tl-based oxide superconductor
Inventor: NAKAJIMA OSAMU
IPC: C01G1/00
Filed: 1990-11-05
Abstract: PURPOSE:To surely obtain Tl-based oxide superconductors whose critical temp. are regulated to values in the desired ranges, respectively, in respective compositions by specifying heat treatment conditions in the manufacturing process and also performing rapid cooling. CONSTITUTION:A mixed raw material in which metallic elements constituting a Tl type oxide superconductor are mixed in the prescribed ratio is calcined at 800-950 deg.C in an oxygen-containing atmosphere. Subsequently, the resulting calcined compact is cooled slowly in an oxygen-containing atmosphere. Then, reheating is exerted in vacuum or in an inert-gas atmosphere, and, when the calcined compact reaches the prescribed temp., this sintered compact is cooled rapidly. As the inert gas, nitrogen is preferred. The above-mentioned method is effective, in particular, for Tl2Ba2Can-1CunO2n+4 as the Tl type superconducting oxide.

Title: Spectrophotometer
Inventor: EHATA YOSHISADA
IPC: G01J3/02
Filed: 1990-11-05
Abstract: PURPOSE:To make it possible to perform highly accurate measurement by one measurement without the effects of polarized light, the fluorescence emitted from a sample to be measured and the shape of the sample to be measured by providing a depolarizing plate between a spectroscope which transforms white light into monochromatic light and a sample chamber. CONSTITUTION:The light from a white light source is transformed into chromatic light in a spectroscope 2. The monochromatic light which does not have a polarizing characteristic is obtained with a depolarizing plate 3. The light is cast on a sample to be measured 8 in a sample chamber 4. The transmitted light is cast into a detector 5. When the monochromatic light without the polarizing characteristic is used, there is no effect of polarized light, fluorescence is not generated and there is no effect of the fluorescence. In this constitution, the length of the optical path between the sample and the detector becomes short. The highly accurate measurement of the spectroscopic luminous intensity can be performed by one measuring without the influence of the shape of the sample. When the reflected light from the sample is detected, the same procedure can be used.
