Title: Method for reducing sludge generated when heavy metal is removed from waste liquid
Inventor: MATSUMOTO TATAE
IPC: C02F1/52
Filed: 1999-03-03
Abstract: PROBLEM TO BE SOLVED: To reduce generated sludge remarkably by a method in which filtered iron hydroxide sludge is dissolved in a HCl solution, with pH adjusted, added into waste liquid of a next lot, and used again. SOLUTION: When waste liquid containing heavy metals is treated, the waste liquid is introduced into a waste liquid tank 1, added with iron chloride containing HCl, and neutralized by NaOH in a neutralization tank 2 to generate iron hydroxide, which is sent a precipitation tank 3. The flock of iron hydroxide adsorbing heavy metals is precipitated, treated water in the upper part is separated, and the separated supernatant is discharged. The precipitated flock of iron hydroxide adsorbing heavy metals is filtered by a filter 4, iron hydroxide sludge is preserved, and the filtrate is returned to the tank 1. Next, the iron hydroxide sludge containing heavy metals which was filtered by the filter 4 is introduced into a pH adjustment tank 5, added with HCl, and returned to the tank in which waste liquid of a next lot is stored, with iron chloride which adsorbed heavy metals left untouched.

Abstract: PURPOSE:To reduce the number of times of rewriting and to prevent the generation of a plotting delay by setting up plotting to a stop state for a prescribed period in which a stop signal is outputted. CONSTITUTION:An NC program analyzing part 1 in a numerical control part 10 analyzes an inputted NC program and outputs a tool moving command CMD.

IPC: G01B7/00
Filed: 1980-04-30
Abstract: PURPOSE: To detect the relative displacement between the two distance sensors distributed in opposition to each other after a conversion into a reduced relative displacement, by putting in a wedge-shaped target member between the two sensors and then shifting in parallel one surface of the target member toward one of the two sensors to obtain the sum of the output voltage.  
     CONSTITUTION: A wedge-shaped target member 3 is put in between the housings 1 and 2 of distance sensors distributed in opposition to each other, and a surface 31 is set parallel to the housing 1. The impedance of coil 11 varies according to the distance between the surface 1 and the coil 11. Then the unbalanced voltage of an impedance bridge comprising the coils 11 and 12 plus resistances 13 and 14 is applied to the resistance 15. In the same way, the unbalanced voltage corresponding to the distance between the surface 32 and coil 21 is applied to the resistance 25. These two voltages are added together through an operational amplifier to be delivered 44. Then the target member 3 is shifted in parallel to the surface 31. As a result, the displacement of surface 32 to the housing 2 can be detected in the form of a relative displacement that is obtained by reducing the displacement between surfaces 31 and 32.
