Title: Preparing and purifying process for succinic acid
Inventor: DEEBUITSUDO EI GURASUNAA
IPC: C07C51/02
Filed: 1989-12-28
Abstract: A process for producing and purifying succinic acid comprises growing a succinate salt-producing microorganism on an inexpensive substrate containing carbohydrate, other nutrients, sodium ions and tryptophan under a CO2 partial pressure until most of the carbohydrate is converted to succinate. The fermentation broth is then electrodialyzed to recover and concentrate the succinate salt in an aqueous stream which is subjected to water-splitting electrodialysis to form base and a succinic acid product. The resulting succinic acid product is treated first with a strongly acidic ion exchanger in the acid form to remove any sodium or other cations and then treated with a weakly basic ion exchanger in the free base form to remove any sulfate ions or sulfuric acid and to obtain a highly purified succinic acid product.

Title: Anisotropic light scattering film and liquid crystal display device using the same
Inventor: SATO ATSUSHI
IPC: G02B5/32
Filed: 1998-12-07
Abstract: PROBLEM TO BE SOLVED: To obtain an anisotropic scattering body of which the color of display light does not change depending on an observer's position by generating light scattering with respect to the incident light along the angle of the inclined direction and functioning as a mere transparent film with respect to the incident light with the angle vertical to the inclined direction. SOLUTION: Light scattering occurs with respect to the incident light 2 on the anisotropic light scattering film with an incident angle θ along the inclined direction of laminatedly distributed parts with different refractive indices, and with respect to the incident light 3 on the film with the angle vertical to the inclined direction, the film functions as a mere transparent film so as to make the incident light exit without scattering. Thus, the light, scattering film 1 has the light scattering selectivity dependent on the incident angle, generating light scattering with respect to the incident light 2 on the light scattering film 1 with the specified angle θ, and on the contrary, functioning as the mere transparent film with respect to the vertical incident light 3.  As a result, the light 2 which needs scattering property and the light 3 which does not need scattering property can be separated by using the incident angle on the light scattering film 1 so as to reduce blur of the.display image.
