Abstract: A method for producing chitosan from naturally occurring chitin-containing raw material, such as crustacean shells, includes an optional pretreatment step to remove non-chitin rich organic material for example, shrimp flesh, from the raw material, e.g., shrimp shells. The optional pretreatment is followed by a demineralization step utilizing a mild hydrochloric acid solution and a deproteination step utilizing a mild sodium hydroxide solution. The deproteination step is followed by a deacetylation step to remove the acetyl group from N-acetylglucosamine (chitin) to form an amine group, yielding d-glucosamine (chitosan). Each step is followed by a washing step and the product is dried, preferably at a temperature not in excess of about 65° C. Known purification and grinding steps may also be used to produce the final chitosan product. The process is carried out in equipment comprising a series of substantially identical or similar tanks (18, 26, 36, etc.) and dryers (62, 62?), suitably interconnected.

Abstract: An orientation controller which divides a pixel into a plurality of different priority alignment regions and an additional orientation controller are provided in a pixel. The additional orientation controller is provided at least at an end of a pixel of a long-side alignment region formed along the long side of the pixel among the divided alignment regions, for example, around a center position of the long side of the pixel. The additional orientation controller can be realized, for example, by forming a cutout pattern in a side of a first electrode (pixel electrode) forming a part of the pixel. Because the alignment direction is also controlled by the additional orientation controller, the alignment of liquid crystal in this region is stabilized.

Abstract: In image processing in which each small area included in color image data, which is represented by C, M, Y, and K, is expressed by a predetermined number of representative colors, values of color parameters are obtained for a small area from the values of the color parameters for C, M, Y, and K for each pixel in the small area, so that the values of the color parameters have degrees of variation being compensated to become smaller in the group as the value for black becomes larger. One color parameter to be targeted is selected (#104) based on the degree of variation in the values of individual color parameters in the group. A reference value to be used for grouping the pixels is obtained based on the relationship between the values of the color parameter to be targeted in the group and the quantities of pixels in the group. Based on the reference value, the pixels are divided into groups (#106), and a representative color for each group is obtained (#109).
