Title: Denitrification of nitrite by chemical treatment
Inventor: NAKANISHI HARUO
IPC: C02F1/70
Filed: 1988-02-20
Abstract: PURPOSE:To cause gasification by a denitrification reaction by esterification of crude water, and to remove nitrite nitrogen of the crude water in a short time by carrying out aeration of the crude water at room temp. under normal pressure by adding a denitrifying agent to the crude water after adjusting the pH of the crude water contg. nitrites to acidic pH with H2SO4. CONSTITUTION:pH of crude water 5 contg. nitrites is adjusted to acidic pH of about 4 pH with H2SO4 in a pH adjusting tank 1 by adding H2SO4 and sirring with dispersed air. The water is then transferred to a denitrification tank 2 where the pH is adjusted to 2-3 by the addition of H2SO4. At the same time, an denitrifying agent such as methanol, etc., is added to the water and the water is aerated. Thus denitrification reaction is processed at room temp. under normal pressure. By this treatment, an esterification denitrification reaction occurs, causing gasification of nitrites in a short time, and the nitrites are removed in the form of nitrite nitrogen.

Title: Operation unit of tape recorder
Inventor: ARAYA AKINORI
IPC: G11B15/02
Filed: 1979-03-27
Abstract: PURPOSE: To reduce the cost price by providing a release plate etc. to release a lock operation, etc., and by constituting one electric plunger so that it can release lock of all modes.  
     CONSTITUTION: In the tape fast-winding mode, reproducing lever 3 and fast-winding lever 2 are stopped simultaneously. For example, when the part between tunes of the tape is detected to flow a current to solenoid in this mode, electromagnetic solenoid 9 becomes a suction state to move release plate 10 of lock in the arrow L direction. Then, release plate 10 is so constituted that the first lock plate 5 may be moved in the movement direction of iron core 9, etc., even if the second lock plate 7 stops the operation through lock plates 5, 7 and iron core 9, etc. Therefore, fast-winding lever 2 whose stop dependent upon the first lock plate 5 is released is reset to spring 11 to perform automatic playing from the beginning of a tune. Thus, lock of all modes can be released by one electric plunger, so that the cost price of the tape recorder can be reduced.

Abstract: PROBLEM TO BE SOLVED: To detect trouble of parts surely and also part trouble in an early stage at the usual use time, in a running test at the production time. SOLUTION: A cumulative operation time of a power source.backup circuit is memorized on E<2> PROM.5. A trouble detection threshold value is calculated by a micro-computer 2 based on the characteristic showing the cumulative operation time and parts trouble. Then, the capacity value of a condenser C as one sample of part is calculated by the micro-computer 2. The microcomputer 2 compares the calculated trouble detection threshold value with the capacity value and when the capacity value is less than the trouble detection threshold value, it is judged that the condenser C has trouble and this is recorded on a record block 3 and also warning lamp 4 is lightened.
