Title: Cell culture substrate and production thereof
Inventor: TAKAHASHI YOICHI
IPC: C12N5/00
Filed: 1989-01-26
Abstract: PURPOSE:To obtain a cell culture medium, excellent in adhesion and propagating properties of cells and capable of advantageously culturing the cells by forming a fine pattern having regularity on the surface of a substrate. CONSTITUTION:For example, a desired pattern is drawn on a substrate consisting of a polyacetal, polyamide or polystyrene, with ultraviolet rays, ionizing radiation, electron beams, ion beans or laser beams. Thereby, the substrate in the part irradiated with the beams is slightly deteriorated to form the pattern having surface energy different from that in the unirradiated part. Any pattern having the regularity can be formed as the pattern in this case and a pattern consisting of lines and spaces is especially preferred. The size of the pattern is especially preferably about 50Angstrom  to 500mum. The depth thereof is normally suitably about 0.01-100mum. Cells can be stably adhered to the surface of the substrate and propagated for a long period by forming the above- mentioned pattern.

Abstract: PURPOSE:To work compressed powder body of alloy powder into a final desired shape at a stroke in one stage, decrease the number of working processes, and improve production efficiency, by a method wherein rare earth alloy powder is enclosed by can material, subjected to rolling in this state by a milling roll having a concave surface corresponding with a convex surface, and at the same time, subjected to bending process. CONSTITUTION:An anisotropic magnet is manufactured by molding rare earth alloy powder for a magnet use in a specified shape, and then magnetizing it. The rare earth alloy powder is enclosed by can material, and subjected to rolling by using milling rolls 12, 16 having a concave surface 14 corresponding with a convex surface 10. At the same time, bending process is performed so as to obtain a specified form corresponding with roll shapes. After that, a molded body 18 is magnetized in the orientation direction of an axis of easy magnetization. For example, after a hollow can of 36Ni steel is filled with alloy powder of Fe-30Nd-1R (wt.%), vacuum deaeration is performed. By using a barrel type milling roll 12 having a convex surface 10 of a circular type and a dram type milling roll 16 having a corresponding convex surface 14, rolling is performed and, at the same time, is molded in a shape whose section is a circular arc. Then the molded body 18 is magnetized by applying a magnetic field in the direction of plate thickness.

Abstract: PURPOSE:To prevent increase of the temperature of a framework without using insulation or the like by providing a wall assembly a part of which, opposed to another part, has approximately the same size as the height of a hot plate and by forming air holes through the bottom of the framework. CONSTITUTION:The heat transmitted from a hot plate 1 toward a guard 6 is shut off by a gap 10 and the radiant heat emitted from the hot plate 1 toward a first part 6a of a wall assembly is shut off by a second part 6b of the wall assembly. Thus the rise of the temperature of the first part 6a of the wall, which a user's hand directly touches, is suppressed assuredly. Furthermore, a heat reflective layer 8 is formed on the inner side of the first part 6a of the wall and on the inner and the outer sides of the second part 6b of the wall so that the radiant heat is reflected effectively, and through a bottom plate 5 and along its borders are formed air holes 11 so that through the passage 12 for air leading therefrom to the gap 10 are passed flows of cold air from under the framework 3 and up the second part 6b of the wall. The combined effect of these features enables suppressing the rise of the temperature of the guard 6 more intensively.
