Title: Method for formation clear interface between erythrocyte layer and granulocyte layer
Inventor: WARDLAW STEPHEN C
IPC: G01N33/50
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To suppress an erythrocyte repulsive force generated by the zeta potential of an erythrocyte by a method wherein micelles, in a definite quantity, which are composed of a plurality of kinds of high-molecular-weight particles and which comprise a positive surface charge are mixed with a blood sample and a blood-micelle mixture is centrifuged in a transparent tube. SOLUTION: A test assembly samples an anticoagulation-treated whole blood sample so as to be centrifuged by using a transparent tube 2. The centrifuged blood sample is separated into an erythrocyte layer 8 of layer specific gravity, a soft layer 10 and a blood plasma layer 12 according to specific gravity. The soft layer 10 is composed of three main component layers as a granulaocyte layer 14, a lymphocyte/a monocyte layer 16 and a thrombocyte layer 18. When a combination of high-molecular-weight cation molecules is added to the blood sample, the interface 20 between the erythrocyte layer 8 and the granulocyte layer 14 is partitioned clearly. A combination of reagents which neutralize and reduce the repulsive effect of the zeta potential of an erythrocyte is added to the blood sample.  A proper combination in a solution forms compound micelles which are useful as an erythrocyte aggregation and a linked-form promoter.

IPC: B07C5/344
Filed: 1994-11-16
Abstract: PURPOSE: To obtain an easy-to-use waste can crusher that has high performance with little maintenance inspection by constructing its sensor sorting device with a metal sensor for iron/aluminum and a shutter for preventing an erroneous detection. CONSTITUTION: A sorting device is provided with a port 2 for feeding waste cans, shutter 5 and rear door 14; when a waste can thrown in is larger than a prescribed dimension, it is detected by an optical sensor 13; the closing of the shutter 5 and the signal of the optical sensor 13 are then displayed with an alarm through a timer function; and the discharge/removal is instructed. The door 3 of the feeding port is provided close to the feeding port 2 and, if two waste cans are thrown in successively, a succeeding object is once stopped by the shutter 5; therefore, double detection is prevented without fail. In addition, since the body of the detecting part 1 is V-shaped, an object thrown in is detected adequately closely to sorting (metal) sensors 11, 12 regardless of the size of the shape, sorted and processed without error.

Title: Porous filter
Inventor: USHIKI KENICHI
IPC: B01D39/14
Filed: 1998-10-27
Abstract: PROBLEM TO BE SOLVED: To enable the clogged part of a filter from being automatically peeled and removed by making the surface layer of one of the faces of a filter laminated and porous with a constituent non-uniformly filled layer formed of a flocculating fine powder molded by compression. SOLUTION: When a laminated porous matter for a laminated porous filter 1 is manufactured, first a combustible organic powder is dispersed in a flocculating fine powder, and these powders are compression-molded. After this molding process, the flocculating fine powder packed non-uniformly in a laminar fashion is sintered. Thus pores are formed by burning the combustible organic powder to disappear and the laminated porous matter is manufactured. When suspended particles 3 are filtered from a fluid by the filter 1, the fluid containing the suspended particles 3 is made to pass through the filter 1 for filtration. Consequently a clean fluid 4 is obtained and the separated suspended particles 3 become a laminated particle layer 2.  When the pressure loss of the filter 1 becomes gradually large by the laminated particle layer 2, the clean fluid 4 is made to flow to the suspended particle 3 side through the filter 1, and the laminated particle layer 2 is separated from the filter 1.

Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To obtain a lead material having small internal residual stress and excellent etching workability by making the elongation percentage of the applying of a tension leveler to a copper alloy for the semi-conductor lead material after finish temper roller lower than a specific value and specifying the condition of a low temp. annealing or a continuous annealing executed thereafter. SOLUTION: To the copper alloy for the semi-conductor lead material after finish temper rolling, the tension leveler is applied at <0.2% elongation percentage and, successively, the low temp. annealing for heating at 200-500 deg.C for 5-300min or the continuous annealing for heating at 300-800 deg.C for 5sec-5min is executed. Thereafter, the tension leveler or roller leveler may be applied at <0.2% elongation percentage. In the case of >=0.2% elongation percentage, the internal residual stress with the tension leveler is largely loaded and such a large stress is not sufficiently eliminated in the following low temp. annealing process.  By a low temp. annealing thereafter or continuous annealing at a temp. lower than the lower limit for a period shorter than the shorter time limit, the internal residual stress is not sufficiently eliminated, and at the time of etching work, the warpage to a die pad part is developed.
