Title: Painting method
Inventor: YAMANE TAKAKAZU
IPC: B05D3/00
Filed: 1987-02-10
Abstract: PURPOSE:To enhance the smoothness of a painting surface by dispensing with a water sanding process, by a method wherein paint is dried while an object to be painted, which is coated with intermediate coat in a thickness equal to or more than a dripping limit, is rotated around a horizontal axis and top coat is applied without performing water sanding. CONSTITUTION:The spraying of intermediate coat in an intermediate coating process P2 is performed to that the thickness of a paint film becomes a dripping limit or more and, in the next setting process P3 and baking process P4, the intermediate coat is dried while an object W to be painted is rotated in the rotary axis extending in the horizontal direction. As a result, since the obtained intermediate coat film has sufficiently high smoothness, the smoothness of the final painting surface obtained after top coating becomes sufficiently excellent even when no water sanding is performed and, in addition, the thickness of top coat is reduced as much as possible to make it possible to achieve cost reduction.

Title: Surface-protective adhesive sheet
Inventor: TABATA HARUO
IPC: C09J7/02
Filed: 1981-02-25
Abstract: PURPOSE: To obtain the titled sheet enhanced in releasability and reduced in an amt. of residual paste, by subjecting the surface of an adhesive in said sheet to high-frequency sputter etching.  
     CONSTITUTION: The surface of an adhesive in a surface-protective adhesive sheet is subjected to high-frequency sputter etching, whereby an atom and molecule in the polymer constituting the adhesive is expelled by collision with a  cation, which reduces thickness of the adhesive and crosslinks the activated  polymer. If a low-molecular component causing the remaining of the paste is  produced on the surface of the adhesive, it is expelled from the adhesive during  the sputter etching, so that it does not remain in the adhesive. Therefore, the  adhesion of said sheet is substantially constant without remarkable enhancement, and no paste remains on an adhered surface after release because of the  absence of any low-molecular component.

Title: Blood-collecting tube
Inventor: TASHIRO KATSUSHI
IPC: A61B5/15
Filed: 1995-01-09
Abstract: PURPOSE: To prevent a precipitation layer and a supernatant layer from being mixed and to improve convenience of an assaying work using blood by using a material hardenable by a light energy given from the outside as a separation material for a separation film between a blood corpuscle component and blood serum or plasma component. CONSTITUTION: Blood which is collected in a blood-collecting tube is separated by centrifugation into a blood corpuscle portion 5 and a blood serum or plasma portion 6. Since a separation material 3 has specific gravity smaller than that of the blood corpuscles and heavier than that of the serum or plasma, it is positioned on the blood corpuscle portion 5 and under the serum or plasma portion 6, that is, at the boundary face of the blood corpuscle portion 5 and the serum or plasma portion 6. In such a state, ultraviolet rays are irradiated to the separation material 3 which is positional at the boundary surface and functions as a separation film, thereby hardening the separation material 3.  The separation material 3, which is hardened once, becomes a separation film having a physical strength and is not destroyed by a force applied from the outside, and prevents the blood corpuscle portion 5 and the serum or plasma portion 6 from being again mixed.
