Title: Stirrer for eia analyzer
Inventor: WAKATAKE KOICHI
IPC: G01N35/02
Filed: 1985-12-06
Abstract: PURPOSE:To reduce the size of an immunological measurement (EIA) instrument by rolling beads in vessels by the attraction and repulsion effects of magnetic materials thereby stirring reactive liquid. CONSTITUTION:The strongly magnetized beads B are housed in the vessels 4. The beads B are held attracted to permanent magnets RN if the magnetic field in the lower part of the beads B are an S pole and the magnets RN facing a base body (r) are an N pole. The beads do not, therefore, roll in the vessels 4. The magnetic field, on the bottom surface of the beads B and the magnetic field of the magnets RS have the same S pole when the vessels 4 are transferred atop the magnets RS. The beads B are, therefore, rolled by the repulsion effect in the vessels 4 so that the magnetic field of the bottom surface thereof changes to the N pole. The reactive liquid in the vessels 4 is thereby stirred. The rolling effects are repeated by the transfer of the vessels 4 in the above-mentioned manner, by which the reactive liquid in the vessels 4 is thoroughly stirred. Since the stirring of the reactive liquid is executed by utilizing the beads essential for the EIA analysis in the above-mentioned manner, the constitution is made extremely simple and the size of the instrument is reduced.

IPC: H01M4/80
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To provide a current collector having through holes which active material hardly comes in and gas permeates with ease. SOLUTION: This current collector is formed of a banboo blind like perforated one formed out of a metallic foil provided with a plurality of through holes, each hole is so determined in shape that its major diameter is in a range of 5 to 1000 μm, and its minor diameter is in a range of 2 to 100 μm. In this case, a ratio of the major diameter to the minor diameter for the respective through holes is 2.5 <= major diameter/minor diameter <=100. The metallic foil is made out of a copper foil, a copper alloy foil, an aluminum foil, and of an aluminum alloy foil. This current collector is used when a negative electrode or a positive electrode is manufactured for a polymer cell and a lithium cell. In order to manufacture such a current collector, a metallic sheet is merely rolled spread, so that the through holes may be manifested automatically.  This is because when the metallic sheet is rolled spread beyond its working limit, slipping occurs at specified crystal planes, and the through holes in the aforesaid shapes can thereby be manifested automatically.
