Title: Biological denitrification of waste water
Inventor: SUZUKI TAKAYUKI
IPC: C02F3/00
Filed: 1987-05-28
Abstract: PURPOSE:To enhance a dehydration property, by utilizing the denitrifying bacteria adhered to the granular medium of a denitrifying process and successively treating waste water through the denitrifying process under an anaerobic condition and an aerobic autodigesting process. CONSTITUTION:Waste water 1 enters a nitration process 2 to nitrate a nitrogen component to NO3 and the nitrated water 3 containing only NO3 flows in a denitrifying process 5 along with methanol 4 to be subjected to denitrification. The waste water 1 directly flows in the denitrifying process 5 through a bypass flow passage 1' if necessary to receive treatment. The excessive denitrifying bacteria propagated in the denitrifying process 5 follows outflow water along with a granular medium to be transferred to an aerobic autodigestion process 6 through a medium transfer pipe 7 and, simultaneously with the removal of the residual methanol 4, said bacteria receive autooxidation and decomposition, and the quantity thereof gradually decreases. By this method, treated water 9 having good water quality can be obtained efficiently.

Title: Solid polymer type fuel cell
Inventor: URABE KYOICHI
IPC: H01M8/04
Filed: 1999-05-11
Abstract: PROBLEM TO BE SOLVED: To prevent a catalyst layer and an ion exchange resin film from drying by including a first water-absorptive region exposing inside a gas feeding side manifold, a second water-absorptive region exposing inside a gas exhausting side manifold, and a third water-absorptive region for connecting the first and second water-absorptive regions with each other in a cell. SOLUTION: Since water is produced by a battery reaction in a cathode. an oxidizer gas abuts on a catalyst layer 9 and is humidified so that it becomes one containing a considerable quantity of water in a gas exit manifold. When it passes a water-absorptive sheet 11 of an ion exchange resin film/electrode joint body 2 corresponding to the position of the gas exit manifold, the water is absorbed. The absorbed water moves inside the water-absorptive sheet 11, and the water-absorptive sheet 11 corresponding to the position of the gas exit manifold is brought into a state containing water as well. Therefore, since a gas successively passing a gas entrance manifold is humidified, the catalyst layer 9 and the ion exchange resin film 8 abutting on the gas keep a certain quantity of water without having the water taken away.

Abstract: PROBLEM TO BE SOLVED: To simultaneously binarize plural pixels without increasing costs by simultaneously binarizing the data of plural pixels based on a set slice value while using either a high-order byte or a low-order byte at least. SOLUTION: When storing multilevel slip image data into a multilevel image memory 3, the high-order bits of multilevel slip image data composed of 2 bits/pixels are distributed to the high-order byte side of one address and the low-order bits of multilevel slip image data composed of 2 bits/pixels are distributed to the loworder byte side. When 8 pixels are stored, data are temporarily held and stored in the multilevel image memory 3. By repeating this operation, the multilevel slip image data are stored in the multilevel image memory for one slip. A binary slice part 4 receives a signal showing an image data area for performing character read and a slice value for performing binarization, segments an image area for character read, binarizes it and stores binarized data into a binarized pattern memory 5.

Filed: 1996-04-26
Abstract: PROBLEM TO BE SOLVED: To considerably deteriorate only image quality of a reproduced image from a VTR(video tape recorder) after dubbing without deterioration in the image quality of a reproduced image on a television receiver in the copy guard method for the video signal for a home use analog VTR. SOLUTION: Copy prevention signals (b), (c) with phases different from a substantial phase of a burst signal (a) are inserted to part of a front side and a rear side of the signal (a). This is conducted in the unit of blocks of several to several tens lines as shown in a caption (d) and it is arranged for several tens to several hundred lines. Moreover, a copy prevention signal is inserted as a whole as shown in a caption (e) to enhance the effect. Moreover, an image of a television receiver is made stable by providing lines where no copy prevention signal is inserted as shown in a caption (f). When the signal receives low frequency conversion by a VTR, the duty of the signals (b), (c) is extended and the reproduced image is deteriorated.  Since the copy prevention signal is inserted only part of the signal (a), the image is displayed on the television receiver normally before low frequency conversion. Since the low frequency conversion of the VTR is utilized, the image quality deterioration between the television receiver and the VTR is made different.
