Title: Method of growing large single crystals from many seed crystals
Inventor: BURUUSU FUAIITSUU CHIYAI
IPC: C30B7/00
Filed: 1984-04-24
Abstract: A large single crystal of metal orthophosphate is grown from a plurality of seed crystals by first mounting the seed crystals with one planar surface of each seed crystal substantially in contact with a planar surface of an adjoining seed crystal and a second planar surface substantially parallel to a second planar surface of the adjoining seed crystal. By known methods, the seeds are then grown into a large single crystal in an acid medium at elevated temperatures. The process is particularly useful for growing large crystals of berlinite, which can then be cut into wafers useful in surface acoustic wave devices.

IPC: B01D53/04
Filed: 1990-03-29
Abstract: PURPOSE: To efficiently reduce the oxygen concn. in an oxygen-contg. gaseous compsn. by mixing this gaseous compsn. and anhydrous alcohol, then heating this mixture, bringing the mixture into contact with an ammonia cracking catalyst to form hydrogen and nitrogen and reacting the hydrogen with the oxygen to form water. CONSTITUTION: A gaseous mixture 3 is produced by mixing the oxygen-contg. gaseous compsn. (e.g. a nitrogen product stream by a pressure swing adsorption process) 1 and a certain amt. of the anhydrous alcohol 2. A heating coil 601 internally packed with the ammonia cracking catalyst (e.g. a catalyst formed by depositing platinum or the like on an alumina support) is arranged in a reactor 300. The gaseous mixture 3 is injected into this reactor 300 and natural gas 4 is combusted to induce the reaction within a pressure range of 10 to 15 psig and a temp. range of 1500 to 1700  deg.F. Namely, the ammonia is dissociated to form the hydrogen and the nitrogen, by which the hydrogen is reacted with the oxygen to form the water and, consequently, the oxygen concn. in the gaseous mixture 3 is reduced. The thus resulted gaseous compsn. is cooled to remove the moisture.

Title: Detector
Inventor: GOTO YUICHI
IPC: G01K13/02
Filed: 1985-04-19
Abstract: PURPOSE:To detect average property of fluid by letting the fluid flowed in from plural inflow ports of a fluid duct flow out from an outflow port utilizing pressure difference and detecting property of the fluid by a detecting element provided near the outflow port. CONSTITUTION:The device is provided with a fluid duct 1, plural inflow ports 2 provided opposite to the flow and an outflow port opened in the direction of the flow, and a detecting element 4 is provided near the outflow port. As the pressure of the inflow port 2 is opposite to the direction of flow, it becomes higher than that of the outflow port by the value of dynamic pressure of the flow. Accordingly, air flowed in from plural inflow ports by pressure difference is mixed in the duct 1, and even if temperature of the air at inflow ports is different, it becomes an average state of temperature near the outflow port, and discharged from the outflow port 3. Consequently, by installing a detecting element 4 at this position, average temperature can be detected easily by a detecting element.
