Patent KR-19990082600-A (KR)
IPC: G01F1/44
Filed: 1997-01-22
Abstract: A non-contaminating flow meter having an isolation member is disclosed. The flow meter includes two pressure sensor transducers, located on opposite sides of a restriction in a conduit. Each of pressure transducers is isolated by an isolation member from exposure to fluids flowing through the conduit. The flow meter may be positioned in-line within a fluid flow circuit carrying corrosive materials, wherein the square root of the difference in pressure between the two pressure sensors is calculated to thereby determine the rate of flow within the fluid flow conduit. The flow meter compensates for changes in temperature within the fluid flow circuit and further activates an alarm if the pressure or flow rate within the fluid flow conduit exceeds or falls below a threshold level. The flow meter of the present invention also avoids the introduction of particulate, unwanted ions, or vapors into the flow circuit.

Title: Field emission triode, device based thereon, and method for its fabrication
Inventor: ZHIRNOV VIKTOR VLADIMIROVICH
IPC: H01J29/82
Filed: 1997-04-30
Abstract: PURPOSE: A field electron emission triode is based on silicon emitters prepared from an oriented whisker array. The semiconductor nature of the emitters makes it possible to use their high series resistance for making uniform of the field electron emission from large area multiple tip arrays. CONSTITUTION: The whiskers were epitaxially grown on a (111) oriented single crystalline silicon substrate (2) by crystallization from vapor phase according to the vapor liquid solid mechanism. The same epitaxial process is used for preparation of columnar spacers (3, 10) that separate a gate (extracting) electrode (5) from a cathode (8) and an anode (9). Different diameters and heights of tip emitters (1) and of the columnar spacers (3, 10) are formed owing to different metal solvents that are used for initiation/localization of the oriented whisker growth. An additional uniformity of the emission is ensured owing to coating of the emitters with substances that decrease work function of the emitters.
