Title: Blood separating medium and blood separating tube employing it
Inventor: HASHIMOTO SUEYUKI
IPC: G01N33/48
Filed: 1995-10-23
Abstract: PURPOSE: To stabilize the performance by adding an antioxidant and a photostabilizer to a resin containing chlorine of a material for forming a separation layer thereby preventing coloring, discoloring and lowering of the viscosity and specific gravity. CONSTITUTION: Preferably, a chloride of liquid olefin based polymer is employed as a resin containing chlorine while a hindered phenol and a sulfur-containing compound are employed as an antioxidant. A benzotriazole and a hindered amine are employed as a photostabilizer which can suppress production of desalted hydrogen in the resin containing chlorine by itself. The antioxidant can not suppress production of desalted hydrogen sufficiently by itself and requires a photostabilizer. The combination is more preferable than the single photostabilizer. Preferably, the content thereof is set in the range of 0.01-5 pts.wt. for 100 pts.wt. of the resin containing chlorine and sufficient suppression effect can not be achieved when the content is 0.01 pts.wt. or below.  When the content exceeds 5 pts.wt., sufficient compatibility with a material for forming the separation layer is not provided and the inspection values may be effected adversely by elution into the blood.

Filed: 1985-12-05
Abstract: PURPOSE:To determine whether a pattern is formed in a desirable manner or not and to improve the yield, by anisotropically dry etching a layer to be etched while masking it with a two-layer resist pattern. CONSTITUTION:A first layer 6a of resist pattern is formed on a layer to be etched 5 such as a polysilicon layer. Then a second layer 7a of resist pattern is overlaid on the first layer, the second layer 7a being thicker and narrower than the first layer. The layer to be etched 5 is then dry etched anisotropically as it is masked with the stepped pattern 6a and 7a. As a result, a polysilicon pattern 5a having a stepped profile corresponding to the profile of the stepped pattern 6a and 7a is formed in the etched layer 5. It is thereby determined whether the pattern is formed in a desirable manner or not and thus the yield can be improved.
