Title: Artificial inter-pebble contact unit and flowing water purifying device
Inventor: TAKESHITA KOJI
IPC: E02B3/00
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To make it possible to purify environmental water without requiring a large installation space and assure the quality of the water usable as industrial water and disaster preventive water by installing plural plate materials extending in their axial line directions in juxtaposition apart spaced intervals in a frame constituted with apertures connectably to each other. SOLUTION: This artificial inter-pebble contact unit 1 is constituted by installing many corrugated plates 2 in juxtaposition at the specified intervals in the cylindrical frame 1 and forming the unit to a wave-like rugged surface shape which waves along the flow of the water with respect to the water to be treated (raw water) flowing in the axial line direction of the frame 1a. Such intervals Z (usually 30 to 60mm) which allow the water to generate turbulence and not to allow the flow to stagnate are disposed between the respective corrugated plates 2. Such artificial inter-pebble contact units 1 are used by arraying plural pieces thereof in series along the water flow direction in a water flow passage, for example, river, etc., in such a manner that the axial lines of the frames 1a are paralleled approximately with the water flow.  The polluting org. matter in the water to be treated is oxidation decomposed by contact with microorganisms sticking to the surfaces of the corrugated plates 12, by which the water to be treated is purified.

Title: Locating of insulation deterioration point of cable
Inventor: SHIMOKUCHI SUSUMU
IPC: G01R31/11
Filed: 1984-02-29
Abstract: PURPOSE:To enable the locating of a defective point without generating discharge in a return line, by shortening a troubled phase cable and a trouble-free phase cable by a condenser. CONSTITUTION:The remote terminals Xa, Yb of a cable X having an insulation deterioration point and a trouble-free phase cable Y are connected by a high voltage condenser C in order to apply test voltage only to said cable X and remote terminals of branched cables P, Q are opened. Further, the conductor of the cable Y is earthed through a resistor R having resistance larger than cable surge impedance. As a result, high voltage E applied to the cable X is almost allotted to the condenser C and voltage E is not applied to the cable Y and operation is performed only as the core wire of a pulse return line. Therefore, no partial discharge is generated in the cable Y. Then, now, the voltage E is applied from the near terminal Xb of the cable X to generate discharge at a troubled point F and the time difference of the first advance wave returning through the cable to arrive the near terminal Xb of the cable X and a second advance wave passing the remote terminal Xa, the condenser C, the remote terminal Ya and the cable Y from the troubled point F to reach the near terminal Yb is calculated to discriminate the troubled point.

CONSTITUTION:When a small amt. of a molten steel supplied through a long nozzle 2 from a pan 1 into a tundish 3 is dammed up by an overflow gate 11 and stored down to the depth of the gate 11, the low temp. molten steel bath at said part is subjected to plasma arc heating so that the molten metal overflows from the gate 11 at a level X'. The temp. of the molten steel is high and therefore the heating is not required for a standard level Z for which heating is not requied but the molten steel is allowed to overflow from the level 11 at a level Z' by the effect of a front wall 13 and the gate 11. When the level Y at the joint between the pans arrives at the inlet side of a heater C, the wall 13 is immersed in the molten steel and therefore the static pressure in a heating chamber 12 is increased by the supply of the gaseous Ar in the state of heating the plasma arc of the molten steel to lower the molten metal surface down to a level Y' to allow the molten steel to overflow the gate 11 until the gas escapes from the bottom end of the wall 13.
