IPC: F04D27/02
Filed: 1990-05-15
Abstract: PURPOSE: To use an inlet valve for controlling a system by repeating such serial processes that an unload valve closed and opened and the inlet valve is opened and closed when system pressure drops below a second pressure level lower than design pressure. CONSTITUTION: In a controller 28, in the case where a compressor 2 is operated, an unload valve 24 is fully closed firstly, and an inlet valve 18 is fully opened. For maintaining delivery pressure at a constant design pressure level and at a gas flow rate between the design flow level and a minimum flow level, the inlet valve 18 is closed by a necessary amount, and the inlet valve 18 is maintained when it reaches the minimum flow. The unload valve 24 is opened by an amount for maintaining delivery pressure detected by a pressure meter 30 lower than a first pressure level higher than design pressure. When the unload valve 24 remains open beyond a position set point for longer than a first predetermined period of time, the unload valve 24 is fully opened, and the inlet valve 18 is fully closed.  When system pressure detected by the pressure meter 32 drops below a second pressure level, the control steps discussed above are repeated.

Filed: 1990-05-16
Abstract: PURPOSE:To obtain a highly qualified translated sentence accurately expressing the meaning of an original sentence by providing the machine translator with an input storage part, an idiomatic expression storing part, an idiomatic expression deciding part, and a translation control part. CONSTITUTION:The translation control part 4 extracts (step F1) a sentence from the input storage part 1 and sends the extracted sentence to the idiomatic expression deciding part 3.

When the completion is obtained, the decided result is informed to the control part 4 to end the processing of the deciding part 3. The control part 4 determines the range of a document to be simultaneously translated based upon the decided result of the deciding part 3 and applies an instruction to a translation processing part 5. Then, all sentences stored in the storage part 1 have been translated or not, i.e. the translation has been completed or not, is decided, and when the translation of all the sentences has been completed, the processing of the control part 4 is ended, and if untranslated sentence are left, the processing is executed again.

IPC: G01M11/00
Filed: 1987-05-25
Abstract: PURPOSE:To make it possible to elongate measurable distance and to measure the short distance from an incident end to a near broken point, by using an optical switch, connecting a light source and an optical fiber when an emitted light passes, and connecting a photodetector and the optical fiber when reflected light passes. CONSTITUTION:An optical fiber 1 to be measured and a measuring device 2 are connected at an incident end 3. In this constitution, a light pulse is emitted from a light source 4 and inputted into the fiber 1 through an optical switch 6 in a switch state I and the incident end 3. The inputted light pulse is reflected by a far end 7, or reflecting means 8 (e.g., reflecting filters), which are provided at plurality of points distributed in the longitudinal direction, or a broken point 9. The reflected light pulse is returned to the incident end 3. The pulse reaches a photodetector 5 through the switch 6 in a switch state II. The distance to the broken point 9 or the transmitting characteristics can be found by checking the state of the light pulse, which has reached the photodetector 5. When the optical switch is used, the reflected light pulse from the incident point 3 can be cut. Loss at the optical switch is less. Therefore, the measuring distance of the optical fiber can be made long.

IPC: H01L39/06
Filed: 1987-05-25
Abstract: PURPOSE:To simplify and to highly integrate a superconducting printed circuit substrate by cooling a superconductor by an electronic cooling element. CONSTITUTION:When a DC current I flows from a power source 11 from an N-type semiconductor 8 to an electronic cooling element 6, heat is absorbed at a heat absorption contact 9 by the Peltier effect, and heat is dissipated at one heat generation contacts 10a, 10b. When the heat is absorbed at the contact 9, a conductor 5 made of near oxide ceramic superconductor is cooled, or the conductor 5 is cooled through a high thermal conductivity stabilizing material layer 4. When the temperature of the conductor 5 becomes a critical temperature or lower, a superconduction occurs. Thus, an enclosure for containing a superconducting printed circuit substrate, a cooling medium and a device for the medium, and a facility can be eliminated to simplify and to reduce the size of the device. Further, its cooling cost can be remarkably reduced, and its resources can be decreased. Then, the printed wiring substrate can be highly integrated.
