Title: Production of chitosan salt
Inventor: TOKURA SEIICHI
IPC: A61K8/72
Filed: 1989-05-02
Abstract: PURPOSE:To obtain a high purity water soluble chitosan salt in an industrially easy manner by reacting an acid with a solid chitosan in a polar organic solvent. CONSTITUTION:A chitosan salt is obtained by reacting an acid with a solid chitosan in a polar organic solvent. An example for chitosan is one obtained by deacetylating chitin by treatment with a concentrated alkali. Examples of the chitin includes alpha-chitin obtained from Crustacea such as crab or lobster and beta-chitin obtained from Mollusks such as cattle fish. As the solid chitosans used, those in the form of particles or a powder are desirable, and particularly one obtained by deacetylating pulverized chitin is desirable. The pulverization of the starting chitin is desirably performed by pulverizing it to about 80 mesh or smaller with a pulverizer such as a ball mill or a hammer mill.

Title: Image forming device
Inventor: WATANABE YUKIO
IPC: G03G15/00
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To prevent the formation of an image due to improper processing, in control involved in the detection of the film thickness of a photoreceptor in particular. SOLUTION: The film thickness is detected in a short time, during a pre- rotation before the image is formed. When the value of the difference between the value of the detection and a detection signal in the last γ-table switching which is stored in advance is lower than a prescribed threshold and further, the number of copies is >=500, the film thickness is detected during a post- rotation after the image is formed. Switching to a γ-table corresponding to the value at this time is attained. On the other hand, when the value is higher than the prescribed threshold, shifting to a pre-rotation detecting mode is executed to detect the film thickness of the photoreceptor and switching to the γ-table corresponding to the value at this time is attained.

Filed: 1986-05-20
Abstract: PURPOSE:To enhance quality of copy images, by providing the first step of obtaining an ink image on an intermediate transfer body as a mirror image of an original, and the second step of laying a transfer body on the ink image side of the intermediate transfer body and heating to transfer the ink image onto the transfer body, with exposure in the first step and exposure in the second step being carried out in different wavelength regions. CONSTITUTION:In the first step, a filter F for cutting off rays of wavelengths corresponding to a light absorption region of an ink layer 14 is inserted between a light source 11 and the intermediate transfer body 12, thereby preliminarily cutting off the part of rays alpha directed from the light source 11 to the ink layer 14 which part corresponds to wavelengths being absorbable by the ink layer 14. In the second step, the rays from the light source 21 are directly led to the intermediate transfer body 12. Although the ink is heated through exposure both in the first step and in the second step, the wavelength of exposure light in the first step is different from that in the second step. With this arrangement, a clear transferred image with high density is obtained, a ground smearing is prevented, and a high-quality image based on the entire part of a copy is formed.
