The blood letting tube 3 is then removed from the blood letting tube holder after the blood taking is completed. The blood letting tube 3 into which the blood is taken is thereafter put into a centrifugal separator and is subjected to a centrifugal sepn. The blood is thereby separated to the blood cells of upper and lower layers and the member 1 for serum sepn. is positioned between the serum and the blood cells. The member 1 has the intermediate sp. gr. of the blood cells and the serum and further the shape on the aperture end side of the blood letting tube 3 is formed to the curved surface having no recesses and, therefore, the adhesion of the blood-clot is decreased and the serum which is not mixed with the blood serums is obtd. The operation for removing the plug body from the blood letting tube after the blood taking is, therefore, eliminated.

Title: Adhesive and method for mounting electronic component
Inventor: MIYAGAWA HIDEKI
IPC: H05K3/30
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To obtain an adhesive which can be dispensed in a stable amount regardless of a change in ambient temperature by incorporating a specified amount of a heat storage material component in an adhesive. SOLUTION: This adhesive is prepared by incorporating 5-50 pts.wt. heat storage material component having a glass transition point and a softening point at least either of which is 20-60 deg.C to 100 pts.wt. adhesive. The heat storage material used is e.g. a solid epoxy resin powder having a softening point of 59 deg.C or a paraffin wax having a melting point of 45-60 deg.C. When the heat storage is softened or molten, it removes heat from the adhesive to inhibit it from becoming excessively flowable due to the otherwise risen ambient temperature.  To mount an electronic component, this adhesive is applied to a predetermined position on a circuit board at 20-60 deg.C, the component is mounted on the applied adhesive, and the adhesive is cured by heating, Next, after a flux is applied to the circuit board, the board is immersed in molten solder to solder the component and the board together.

Title: Dynamic speaker
Inventor: KAWAMURA SHINICHIROU
IPC: H04R9/06
Filed: 1982-10-18
Abstract: PURPOSE:To utilize a cavity in a magnetic circuit effectively by charging at least one magnetic gap with magnetic liquid, and flowing air from at least one cavity in the magnetic circuit to the space between a diaphragm and the front surface of the magnetic circuit or reversely. CONSTITUTION:The magnetic gaps 8 and 9 are charged with magnetic liquid materials 10 and 11 in order to damp an oscillation system mechanically. Consequently, no air flows in the magnetic gaps, so the cavity in the magnetic circuit is not utilized. Namely, when the diaphragm 3 oscillates by driving force from voice coils 12 and 13, the air surrounding the diaphragm 3 and in the space 20 is compressed and expanded, and its pressure is propagated to the direction at right angles to the center axis of the speaker. For this purpose, bobbin holes 21 and 22 are provided. The pressure exerted by the air in the space 20 is propagated to the cavities 14 and 15 through the magnetic gaps 8 and 9. Then, the cavities 14 and 15 operate as an air-spring to contribute to release the pressure in the space 20.

CONSTITUTION:A through-hole 15 is provided to a specified position on a second interlaminar insulating film 13 deposited on an upper layer, of a first layer Al wiring 11 to make the first layer Al wiring 11 exposed at the base. In this process, the angle theta of inclination of the side wall of the through-hole 15 is made to be about 90 degrees. Next, a sputter etching is performed using Ar<+> ions to remove a natural oxide film formed on the surface of the first layer Al wiring 11. As the angle of inclination of the side wall is nearly 90 degrees, the side wall is prevented from being etched. Next, a tungsten 16 is buried inside the through-hole 15 to make the opening flattened. After that, the second interlaminar insulating film 13 is coated with an Al-Si-Cu alloy film to form a second layer Al wiring 14.
