Title: Phase synchronization storage device and computing apparatus
Inventor: OSHIMA TOSHIO
IPC: H01L29/06
Filed: 1997-06-13
Abstract: PROBLEM TO BE SOLVED: To guarantee that a specific phase state is maintained for a sufficiently long time and to make the error rate of information sufficiently small in a phase synchronization-type storage device and a computing apparatus in which a DC bias is applied to a very small tunnel junction single-electron-effect element, in which an AC pumping signal is applied so as to be phase-synchronized and in which information is stored and computed. SOLUTION: An auxiliary circuit 3, for error correction, which contains a device having the low error rate of information is installed. The refresh operation of information is performed from the auxiliary circuit 3 for error correction at a time interval which is shorter than the time in which a specific phase state is maintained stably. Alternatively, in order to store information which is contained in the time which is equal to, or more than, the time of the reciprocal number of the error rate of information, a plurality of phase synchronization-type storage circuits 1-1, 1-2 or computing circuits which are more than the number of stored bits of information are installed so as to be redundant. In addition, pieces of information which are outputted from the storage circuits or the computing circuits are decided by a majority vote.  As a result, the error rate of information is made a sufficiently small value.

Title: Heat insulating gas sampler for gas chromatograph
Inventor: TSUKUDA IWAO
IPC: G01N30/04
Filed: 1986-07-04
Abstract: PURPOSE:To easily form a calibration curve of a low concn. region for a condensible gas by providing a carburetor having a liquid feed port and gas introducing pipe to a flow passage selection type sampling cock and passing a standard gas to the gas introducing pipe. CONSTITUTION:The standard gas is passed to the gas introducing pipe 10 and is kept passed through the carburetor 3 to a metering pipe 5. A liquid to be inspected is adequately diluted by the standard gas simultaneously with evaporation when said liquid is adequately into the carburetor 3 from the liquid feed port 2 thereof by a microsyringe. The respective component concns. of the standard gas in the resulted chromatograph decrease at a specified ratio as compared to the case in which the liquid to be inspected is not contained therein if the liquid to be inspected is analyzed by a gas chromatograph. Since the decrease correlates with the concn. of the liquid to be inspected, the calibration curve of the low-concn. region of the condensible gas is extremely easily formed by adequately controlling the injection rate of the liquid to be inspected by the microsyringe and the flow time of the standard gas.
