Title: Aluminum nitride powder and its production
Inventor: RAI TAKASHIO
IPC: C01B21/072
Filed: 1992-05-15
Abstract: PURPOSE:To produce aluminum nitride powder surface-coated with an aluminum sulfate coating film and excellent in oxidation resistance. CONSTITUTION:Aluminum nitride powder is treated with a sulfuric acid-contg. org. solvent and dried to industrially produce the objective aluminum nitride powder surface-coated with an aluminum sulfate coating film at a low cost. The oxidation resistance of the aluminum nitride powder can be considerably improved without deteriorating characteristics peculiar to aluminum nitride. Since the aluminum sulfate coating film does not adversely affect the characteristics of a sintered compact, powder storing and handling work is remarkably improved.

Title: System for managing activity identifier
Inventor: TOZONO RYOJI
IPC: H04L1/18
Filed: 1990-05-14
Abstract: PURPOSE:To prevent the occurrence of duplicate utilization of an activity identifier by setting a condition of updating the activity identifier with its own system set to the start side to a minimum range only at retrial-out of error recovery processing. CONSTITUTION:A file is transferred between a starting side data processing section 1 and a response side data processing section 7. An activity identifier control section 3a of the starting side data processing section 1 does not update the activity identifier at the end of file transfer independently of the normal end or the abnormal end but uses a same value (current value) again, and updates the activity identifier when the error recovery processing is in retrial-out and uses a succeeding value (current value + increment). Thus, the occurrence of duplicate utilization is prevented by sending the activity identifier stored at the response side after the retrial-out of the error recovery processing from the starting side is prevented.

Title: Etching method
Inventor: NAKAMURA MORITAKA
IPC: H01L21/3065
Filed: 1986-05-29
Abstract: PURPOSE:To prevent corrosion, by etching an aluminium alloy layer with a resist pattern used as a mask to form an aluminium alloy pattern, removing the resist pattern and dipping the substrate in choline or a derivative thereof. CONSTITUTION:A substrate 1 is provided by a silicon substrate covered with an insulation layer of phosphorus silicate glass or the like.

Title: Treating method for radioactive waste liquid
Inventor: YASUMURA KEIJIRO
IPC: G21F9/28
Filed: 1993-05-26
Abstract: PURPOSE:To allow simultaneous treatment of suspension and water soluble components, e.g. chemical oxygen demand(COD) components, in waste liquid containing detergent components by adding an adsorbent adsorbing a surfactant into the waste liquid. CONSTITUTION:After waste liquid is fed to a conditioning tank 1, active carbon powder is added thereto and stirred through a tank stirring line 2 so that the surfactant (detergent component) in the waste liquid is adsorbed by the power active carbon. A valve 12 is then opened to feed the waste liquid containing the powder active carbon to a rotary filter 4. The waste liquid is filtered through filtering cloths 5 and fed through a line 9 to a storage tank 10. The adsorbent deposited on the filtering cloth 5 is discharged through a concentrated sludge discharge port 8 through the function of rotary stirring impellers 6. The suspension (ravelings, hair, etc.) is separated by subjecting the waste liquid to cake filtering using the filtering cloths 5 and the separated suspension is removed. Since the main component of COD, i.e., the surfactant, is adsorbed and removed, the added active carbon powder can be utilized effectively as an accelerator for fine filtering.
