Title: Filtering method of cmp drain
Inventor: TAIHICHI MOTOYUKI
IPC: B01D63/00
Filed: 2001-04-04
Abstract: PROBLEM TO BE SOLVED: To solve problems in a conventional processing method of CMP drain including the polishings and grindings produced in mechanical work such as dicing and CMP by two ways combining the coagulating sedimentation or filtration and the centrifugation, that in the former processing, a chemical agent is mixed in the filtrate water, so that the filtrate water can not be recycled, and in the latter process, a system is enlarged, which increases the initial cost and the running cost. SOLUTION: A first tank 75 is provided with a second filter 13 made of a solid matter 12, and the drain 73' including the slurry and abrasive grain is continuously poured into a first tank 75. As the solid matter 12 on a surface of the second filter 13 is movable, a filtering device can be prevented from being clogged by the application of the external force such as bubbles to the same.

Title: Fuse link for high voltage
Inventor: HIROSE KENGO
IPC: H01H85/46
Filed: 2001-04-17
Abstract: PROBLEM TO BE SOLVED: To make the arcs generated at adjacent arcking points hard to short- circuit to each other, even if adjacent parts of a fuse wire wound around a bobbin generate arcs simultaneously. SOLUTION: The fuse link for high voltage 11 is formed by winding a conduction body 13 on a cylinder-shaped bobbin 12 having a hollow part 12a. A groove 14 is carved spirally on the outer surface of the bobbin 12, and the conductor 13 is wound spirally, along a groove surface 14a or a ridge surface 14b of the groove 14. A plurality of narrow parts 15 fusing, when an accidental current is cut, are serially arranged on the conductor 13. Since the groove part or the ridge part lies between the adjacent parts of the conductor 13, insulation distance between adjacent parts of the conductor 13 is made large, without widening the winding pitch of the conductor 13, accordingly, the arcs generated at the adjacent arching points becomes hard to short-circuit to each other along the surface of the bobbin 12, even if arcs are generated simultaneously between adjacent parts of the conductor 13.

Title: Filtration equipment
Inventor: KURODA TARO
IPC: B01D29/11
Filed: 2001-05-14
Abstract: PROBLEM TO BE SOLVED: To realize filtration equipment which is hardly clogged even if materials to be removed are captured in a large amount. SOLUTION: The bag-like filtration equipment is provided with a segment where the cross-sectional area of a flow passage is minimized in about the middle thereof. As a result, the fluid flowing into the section where the cross-sectional area of the flow passage is minimal on the upstream thereof is thickened and the filtration treatment of the thickened fluid is performed on the downstream side of the section where the cross-sectional area of the flow passage is minimal. The inflow rate of the fluid to the downstream side of the section where the cross-sectional area of the flow passage is minimal is drastically reduced by thickening the fluid and therefore the good filtration treatment can be carried out even when filter media are clogged and the drastic decrease in the permeation flow rate is resulted.
