Abstract: PURPOSE:To obtain better sticking of methane fermentation bacteria group such as facultative anaerobic bacteria group, etc. and to improve generation of gaseous methane by causing methane fermentation using shells such as surf clam, scallop, ear shell, etc. as contact material. CONSTITUTION:Shells as they are or crushed to certain degree are charged to a methane fermentation tank, thereby the shells may be packed as it is to the fermentation tank or may by packed after wrapping with metallic net successively preventing scattering of individual pieces of the shell. Liquid to be treated such as night soil or excess sludge is mixed in the first place with a medium for cultivating seed for methane fermentation bacteria group, and the mixture is filled in a closed anaerobic tank packed with the shells. When the bacteria are cultured at 20-50 deg.C for ca. a week, groups of methane fermentation bacteria stick to the circumference of the shells to commence methane fermentation. The treated liquid is flowed continuously into the closed anaerobic tank portion- wise, and overflowed treated fermentation liquid is withdrawn.

Title: Semiconductor memory device and its manufacture
Inventor: OKADA YOSHIO
IPC: G11C11/41
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To implant and extract electric charges at a low voltage, by a method wherein a tunnel oxide film is composed of a silicon germanium oxide of a value in which X in the composition is in the specified range, and an islandish germanium area exists in the silicon germanium oxide film. SOLUTION: An Si(1- X) GeX layer is oxidized in epitaxial growth and a tunnel oxide film 2 is formed. An oxidizing method is preferably a dry oxidation at a low temperature of 550 to 800 deg.C. Here, since SiO2 is more thermal- dynamically stabilized than GeO2 , grains of Ge are scattered in an islandish manner in the obtained tunnel oxide film 2 to form an island 21. Further, it is preferable that, in a composition of the tunnel oxide film 2, X is in 0<X<1 and in particular X is 0.15 to 0.40. The reason is that, if X is less than 0.15, density of a Ge island 21 is reduced and a sufficient tunnel current cannot be attained, and if more than 0.40, defects occur in a substrate due to lattice unalignment of Si(1- X) GeX and Si.

This acoustic optical modulator 108 is controlled according to the interference patterns of the holography calculated by a high-speed calculator 110. The pass light of three primary colors is subjected to modulation by a liquid crystal layer 102 in the forward and backward strokes of the liquid crystal layer 102 before the light returns by reflecting at a reflection dielectric mirror 103, by which color holography stereoscopic images are reconstructed and displayed.  The images are formed by making the pitch of the interference fringes of the three primary colors proportional to the wavelengths of the colors of the corresponding color filters, by which the respective images of the three primary colors are formed around the same angle at the time of reproduction of the white light of the holography and, therefore, the occurrence of the color drift is averted.
