Title: Production of raw material powder of oxide superconductor
Inventor: NANAO TSUTOMU
IPC: C01G3/00
Filed: 1988-12-09
Abstract: PURPOSE:To enable the lowering of the synthesis temperature and the formation of single phase, by mixing an alcohol solution of nitrates of copper and a lanthanide metal with an alcohol solution of Ba(OH)2 and a Ba alkoxide, thereby forming a coprecipitate and directly producing the objective material. CONSTITUTION:A coprecipitate is formed by mixing an alcohol solution I of a copper nitrate and a lanthanide metal nitrate with an alcohol solution II of one or more compounds selected from Ba(OH)2 and Ba alkoxide. The objective raw material powder of oxide superconductor can be produced by the thermal decomposition of the coprecipitate. The raw material powder of oxide superconductor is obtained without forming barium carbonate, etc., as an intermediate product by this process. Accordingly, the objective compound can be produced in a short time at a low temperature. Since the process is a coprecipitation reaction from an organic solvent without using an aqueous solution which is unsuitable for the production of oxide superconductor, the trouble of the residual water in the power can be lessened.

Title: Virtual environment generating device
Inventor: KOIZUMI NOBUO
IPC: G06F17/50
Filed: 1992-11-20
Abstract: PURPOSE:To generate virtual environment wherein an image and a sound having presence are synchronized with each other at all times immediately in response to changes of the shape and acoustic characteristics of a virtual space. CONSTITUTION:A user 60 operates an operation part 30 over a look at an image display part 40 to put a three-dimensional space designing and operation arithmetic part 11 in operation, thereby designing a closed space. The designed closed space can be viewed from a specific view point through the image display part 40. Further, the sound from a sound source 20 which reaches the view point can be listened to through a sound reproduction part 50. When the user 50 changes the shape and characteristics of the closed space, the three- dimensional designing and operation arithmetic part 11 sends the sound absorptivity, surface area, etc., of the wall surface constituting the closed space to a reverberation time arithmetic part 12, which estimates a reverberation time. A reverberation adding circuit 13 adds reverberations to the sound signal of the sound source 20 on the basis of the reverberation time and supplies the resulting sound to the sound reproduction part 50.

Filed: 1989-12-05
Abstract: PURPOSE:To measure leakage resistance between lines with high accuracy by taking the difference between the measured parallel value and measured series value in the same resistor at every line with respect to each of a plurality of line resistors arranged in a zigzag pattern. CONSTITUTION:When switches S0, S13 are closed and the remaining switches are opened, the currents flowing through all of line resistors RS can be collectively measured. When there is no irregularity between the resistors RS, the readings of respective ammeters M become equal excepting a terminal wherein there is leakage between adjacent lines and, therefore, it is cleared what part between terminals there is leakage. Next, when switches S0, S2, S4... S10, S12, 813 are opened and the remaining switches are closed, the currents flowing through the resistors RS on the side of terminals T2, T4... T10 are detected. The switches S0, S1, S3... S11, S13 are opened and the remaining switches are closed, the currents flowing through the resistors RS on the side of terminals T1, T3... T9 are detected. AS mentioned above, by taking the difference between the measured parallel and series values in the same resistor at every line, the error due to the irregularity of resistance values is set off and the leakage resistance between lines can be measured with high accuracy.
