Filed: 1991-04-25
Abstract: A cooling apparatus for cooling a given device which is incorporated in a computer or similar electronic equipment and generates heat by circulating a liquid coolant through the device of interest. A secondary cooling liquid exchanges heat with a primary cooling liquid in a heat exchanger and then flows into the device of the equipment. When the difference in temperature between the secondary cooling liquid and the interior of the equipment decreases beyond a predetermined value, a heat exchanging mechanism is caused to stop operating. On the increase of the difference in temperature beyond the predetermined value, the heat exchanging mechanism is caused to begin operating again. Alternatively, the operation of a secondary cooling liquid feeding mechanism may be interrupted and then set up again on the basis of the above-mentioned difference in temperature.

Abstract: Abstract of the Disclosure A method and apparatus are disclosed for forming polycrystalline superconductors of the thallium calcium-barium-copper oxide system, having high current-carrying capacity and high magnetic field behavior.  A polycrystalline precursor comprised of calcium, barium, copper, and optionally thallium, or oxides of the same, having a stoichiometry suitable for forming a polycrystalline Tl-Ca-Ba-Ca-O superconductor is annealed in an oxidizing atmosphere, and in the presence of a source of thallous oxide.  The source of thallous oxide is heated to a first temperature that establishes  a preselected partial pressure of thallous oxide over the precursor, and the precursor is heated separately to a second temperature where the Tl-Ca-Ba-Cu-O superconductor is formed, the first and second temperatures being selected to form a polycrystalline structure having strong current links between grains.     An annealing apparatus for performing the annealing method is comprised of a vessel suitable for containing an oxidizing atmosphere and resistant to chemical reaction with thallous oxide, the vessel having at least two separate heating zones configured to have a common atmosphere for the two zones.  Means for maintaining a preselected atmosphere within the vessel during annealing, heating means for heating the two zones separately, controlling means for heating the zones to predetermined temperatures, and cooling means for cooling the vessel so that the zones are cooled at predetermined cooling rates.

Title: Process and installation for the separation of a mixture of two gaseous components
Inventor: ADELMANN WALDEMAR
IPC: B01D5/00
Filed: 1991-05-21
Abstract: A B S T R A C T Process and Installation for the Separation of a Mixture of Two Gaseous Components In order to separate a mixture of two gaseous components with different boiling temperatures, it is proposed that the mixture be initially compressed and thereupon cooled so that its temperature lies below the boiling temperature of the gas components to be removed. The gas components to be removed undergo condensation and can be led off for reutilization without contaminating the environment. Furthermore, it is proposed to feed the gas mixture through activated carbon filters (4,5) after the condensation process, in order to bind remaining proportions of the gas components to be removed. It is also intended to partially return the gas mixture for renewed liquefaction after it has passed through said activated carbon filters. At the same time, the invention proposes a suitable installation for the execution of this process. - Drawing -

Filed: 1990-07-10
Abstract: In a fuzzy control apparatus in which a rule is capable of being changed during operation, a fuzzy reasoning output which prevails immediately prior to a rule change is stored when a rule change is made, and a fuzzy-control output is generated by combining, after the rule change, the stored fuzzy reasoning output which prevailed immediately prior to the rule change and a fuzzy reasoning output which prevails following the rule change.  The ratio of the combination is altered in such a manner that, with the passage of time from the moment at which the rule change is made, there is a gradual decrease in a percentage of the fuzzy reasoning output which prevailed immediately prior to the rule change, and a gradual increase in a percentage of the fuzzy reasoning output which prevails following the rule change, in the fuzzy-control output.  Upon passage of a predetermined time from the moment at which the rule change is made, the fuzzy reasoning output which prevails following the rule change is outputted as the fuzzy-control output.  As a result, a sudden change in the output at the time of a rule change is prevented so that a smooth changeover can be carried out.
