IPC: C02F1/62
Filed: 1984-02-29
Abstract: PURPOSE:To remove mercury in waste water with good efficiency, by a method wherein an oxidizing agent is injected in mercury-containing waste water to convert mercury to ionic mercury and, thereafter, a reducing agent is added to the treated waste water to form metal mercury and vaporizing gas is subsequently blown into the treated waste water to vaporize metal mercury.

As the oxidizing agent, sodium hypochlorite is used. Next, this waste water is introduced into a reductive reaction tank 2 and subjected to reducing treatment using hydrazine hydrate or stannous chloride for a definite time under stirring to convert ionic mercury in waste water to metal mercury. The waste water after reducing treatment is guided to a stirring apparatus 3 and vaporizing gas is blown into said stirring apparatus 3 to perform gas-liquid contact treatment and metal mercury is allowed to follow the vaporizing gas. As the vaporizing gas, gas not reacted with waste water such as air, nitrogen or argon is used.

Title: Pump having apparatus for preventing deposition of foreign matter
Inventor: MIYAZAKI KAZUAKI
IPC: F04D7/04
Filed: 1980-03-24
Abstract: PURPOSE: To prevent deposition of foreign matter by providing an appropriate gap between a base part of a fixed cutting part and an internal periphery of an impeller intake, communicating said gap to an upper stream side and an intake side via a circular window, and eliminating the stagnation of the reversely flowing water in this part.  
     CONSTITUTION: In the operation of a pump, foreign materials in contaminated water which is sucked to an impeller 15 through an intake are appropriately cut by an engagement between a rotary blade 15a and a fixed blade 19c and exhausted from an exhausting port. The rotary blade 15a is provided at the inside of the impeller 15 and its end is linearly inclined. The fixed blade 19c is provided at the cut out part of a conical part 19b of an intake metal 19 and its outer end is inclined. In this case, reversely flowing water is generated by circulating flow engendered in an impeller groove and low pressure caused in a base part of a conical part 19b of the intake metal 19. Said reversely flowing water is directed to a gap S between a port of a cylindrical part 19c of the intake metal 19 and an internal periphery of the intake of the impeller 15. Said reversely flowing water becomes a circulating flow which easily flows through a path W comprising circular oblong hole 19d of the intake metal 19 since the gap S is relatively wide. Thus, deposited matter are readily removed to the intake side through the path W, and the deposition can be prevented.

IPC: H03K5/19
Filed: 1989-02-16
Abstract: PURPOSE:To detect the abnormality of a pulse signal by monitoring a period when the same level continues for the pulse signal where a pulse train of a fixed cycle should be led out via a shift register. CONSTITUTION:A shift register 2 consists of plural cells F1-Fn which are connected in series, and perform the latching operations based on a clock signal l2 having a shorter cycle than a pulse signal l1. This signal l1 is inputted to the cell F1 of the register 2. A deciding means 3 receives the input of signals from those cells F1-Fn of the register 2, then decides the abnormality of the pulse signal when the coincidence is obtained among the levels of those signals received from the cells F1-Fn. Thus the signals having the same level and received from the cells F1-Fn are outputted when a pulse is omitted and a fixed level is held for a long time. As a result, the abnormality of the signal l1 is detected.
