Title: Pseudo-pancreatic islet and diffusion chamber-type artificial pancreas
Inventor: OGAWARA HISAKO
IPC: A61F2/02
Filed: 1988-03-27
Abstract: PURPOSE:To obtain an artificial pancreas maintaining various functions of pancreatic endocrine cell and usable over a long period, by subjecting pancreatic islet to primary culture in a cystine-free medium and then to three-dimensional culture in a medium added with nicotinamide, etc. CONSTITUTION:A pancreatic endocrine cell is cultured first in a cystine-free culture medium and/or culture liquid in order to suppress the proliferation of fibroblast cell. The cultured cell is further cultured in a culture medium and/or culture liquid added with nicotinamide and/or 3-isobutyl-1-methylxanthine to improve the fugitivity of the pancreatic islet cell in an extracellular matrix such as collagen gel and to proliferate the pancreatic islet cell in a void formed in the matrix and maintain its function. The culture medium, etc., may be further added with cerulein, etc. The reconstituted pancreatic islet produced by the above process is enclosed with a polymer membrane having a pore size to enable the passage of insulin but inhibit the transmission of immune carrier cell. An artificial pancreas usable over a long period can be produced by the above procedure using pancreatic islet which can be cultured over a long period.

IPC: H01F38/24
Filed: 1986-03-31
Abstract: PURPOSE:To relieve electric field of a high voltage winding and make electric stress distribution uniform by employing a plurality of types of insulators with mutually different dielectric constants as layer insulators. CONSTITUTION:A layer insulator 4, which is wrapped with a high voltage winding 3, is composed of a plurality of types of insulators which have different dielectric constants epsilon. From the inside of the high voltage winding 3, a layer insulator 4-1 whose dielectric constant is epsilon1 is applied with necessary turns and then a layer insulator 4-3 whose dielectric constant is epsilon3 is applied with necessary turns and, outside the layer insulator 4-3, a layer insulator 4-2 whose dielectric constant is epsilon2 is applied with necessary turns and a high voltage shield 9 is attached to the outermost part. Although these layer insulators 4-1, 4-2 and 4-3 have different dielectric constants, their dielectric strengths are nearly the same and the relation between the dielectric constants is epsilon2>epsilon1>epsilon3. The optimum winding thicknesses of the layer insulators 4-1, 4-2 and 4-3 are determined in accordance with the diameter, width or the like of the high voltage winding 3. The capacitances between the layers of the high voltage winding 3 can be freely controlled by the values of the dielectric constants epsilon of the respective layer insulators 4-1,4-2 and 4-3.

Abstract: PURPOSE:To prevent lenticulation of the end part and void, etc., in a transfer sheet whose moisture content is large by arranging a pressing member on an upstream which is upper than a corona discharge transfer charger so that the pressing member can contact with and separate from a photosensitive body. CONSTITUTION:A pressing device 9 having a pressing roller 8 functioning as the pressing member is arranged on the upstream side in the moving direction of the transfer sheet for a transfer member as a corona discharge transfer charger 4. When the transfer device is not actuated, it is kept in a position where the plunger of a solenoid 13 is pulled out as illustrated in a figure A and the pressing roller 8 is separated from a photosensitive roller 2 at such a time. When the transfer device is actuated, the solenoid 13 is energized and the plunger is pulled in as illustrated in a figure B, then a supporting lever 18 is moved by turning a lever 12 around a supporting shaft 11, so that the pressing roller 8 moves to a position where it comes into contact with the 2nd photosensitive roller 2. Since the end part of the transfer sheet 5 is pressed by the 1st photosensitive roller 2, the lenticulation of the transfer sheet 5 is made flat. Thus, an abnormal image is not formed in an environment where humidity is high.
