Title: Disposal of sludge
Inventor: KIKUCHI TOSHIYUKI
IPC: C02F11/14
Filed: 1979-04-18
Abstract: PURPOSE: To facilitate the disposal of sludge and conduct efficient dredging by a method wherein a sludge accumulated area is divided into the plural number of blocks, each of which is closed up, the surface water in each block is discharged, and further the sludge in specified blocks is removed, while the sludge in other blocks is transferred into these vacant sections, being given flocculating agents, and the sludge thus condensated is dredged.  
     CONSTITUTION: The sludge accumulated area of a river 1 is divided and closed up into the plural number of blocks AWH by steel sheet-piles 2. Then, after the surface water in the blocks AWH being discharged by an underwater pump (omitted from the figure), the blocks A and B are emptied by dredging sludge therefrom. Next, the sludge in the block C is transferred into the emptied block B, with its gross refuse removed by riddles, gratings 4 and the like. The sludge sent in the vacant block B is dredged by a pump 4 and further transferred into the vacant block A through a piping 5. In the course of this transfer a flocculating agent M is injected into the piping 5 and is churned by a churner 6. The sludge in the block A is condensated by 5W30 minutes for curing. Then the condensated and jellied sludge is dredged by grabs or pumps.

IPC: C23C10/28
Filed: 1986-03-07
Abstract: PURPOSE:To execute coating of the inside and outside surfaces of a metallic pipe which is a base material to easily obtain a good coating having improved adhesiveness without pinholes by irradiating a laser beam to a plating layer formed by plating an alloy element on the surface of the metallic pipe to melt the plating layer to an alloy layer. CONSTITUTION:The plating layer 2 of Cr or Ni-Cr is formed by electroplating to 50-70mum thickness to one of the inside and outside surfaces of the metallic pipe 1 made of a carbon steel or the like which is the base material. A laser beam 3 such as gaseous CO2 laser is irradiated toward the plating layer 2 to melt said layer. The beam 3 is moved in the axial direction A of the pipe in this stage and at the same time, the pipe 1 is rotated to spirally irradiate the beam 3 toward one surface of the pipe 1. The entire surface of the plating layer 2 formed on one surface of the pipe 1 is thereby melted. The plating layer 2 has no pinholes and forms the pinholeless and dense alloy layer 5 having high adhesiveness to the pipe 1. The pipe 1 formed with the coating having the good resistance to corrosion and wear is thus obtd.

IPC: G11C11/40
Filed: 1985-03-12
Abstract: PURPOSE:To completely turn off a non-selected transfer gate transistor by connecting an impedance element lifting the source potential between the ground and source of a pair of driving transistors for flipflops. CONSTITUTION:The sources of the transistors Q5, Q6 connected with the ground are disconnected from the ground and a resistor R is inserted between the sources and the ground in place thereof. At this time, the cell current flowing in the resistor R raises the cell potential to raise the source drain potential of the transfer gate transistors Q9, Q10 so that it is possible to lower the gate potential looked from the source to completely turn off the transistors Q9, Q10 even if the word line potential remains unchanged. In the memory cell MC, the load transistors Q7, Q8 are turned on while one of the driver transistors Q5, Q6 is on. When, for example, Q5 is on, the drain current of Q7 flows in the source of Q5, the drain current of Q8 flows in the gate of Q5, these currents flowing in the resistor R. In such a manner, the transistor gate transistors are turned off to eliminate current leakage.
