Title: Treatment of waste water containing selenium
Inventor: OKAMOTO HIDENORI
IPC: C02F1/70
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To efficiently and quickly remove selenium in waste water from the waste water by adding a reducing agent and neutralizer to the water to react while making the waste water containing selenium flow through plural reaction chambers. SOLUTION: An industrial waste water containing selenium is introduced to a first reaction chamber 1 and stirred by a stirrer, into which a ferrous salt such as iron (II) sulfate as a reducing agent and a neutralizer such as sodium hydroxide to control pH of the waste water to about 8 to 10 are added to react to remove selenium as the coprecipitate with iron from the waste water. The liquid which overflows from the first reaction chamber is introduced to second and third reaction chambers 3, 5 where the water is processed in the same way as in the first chamber. Namely, a reducing agent and a neutralizer are added to produce coprecipitate of the residual selenium with iron, which is removed. Thus, the waste water is discharged in a harmless state.

Filed: 1979-05-10
Abstract: PURPOSE:To obtain the rated output of transformer with small input by a method wherein a transformer coil is cooled with liquid nitrogen to make the specific resistance of the coil to be small. CONSTITUTION:A primary coil 1 and a secondary coil 3 are put in a liquid nitrogen cooler, and are cooled to -198--183 deg.C.

Title: Continuous test system for peripheral device
Inventor: TSUTAGAWA JUNKO
IPC: G06F11/22
Filed: 1990-03-07
Abstract: PURPOSE:To inhibit the continuation of a meaningless test when a data comparison error is produced due to a fixed fault of a peripheral device by ending the test if the data comparison errors exceed continuously a certain level of frequency after the reading actions are carried out in the continuous tests of the peripheral device. CONSTITUTION:The written data are read out and compared with the expected read data. If a data comparison error occurs, a data comparison error message is outputted and then '1' is added to a data comparison error counter. Then the value of this counter is compared with the prescribed value. If the former value is larger than the latter one, a test under execution is ended. Meanwhile it is decided whether a test was carried out to the entire surface of a working medium or not when the counter value is smaller than the prescribed value. If so, the test is ended. Thus it is possible to decrease the meaningless data with which the data comparison error messages are outputted for each reading action of data. Then the test time of a peripheral device is shortened.
