Inventor: DE WINTER HUGO
IPC: B29C45/14
Filed: 2001-07-31
Abstract: L'invention concerne un procédé de production d'une couche de revêtement en polyuréthanne élastomère non cellulaire ou microcellulaire au moyen d'un procédé de moulage, ou plus généralement un procédé de production d'un composite renfermant une première partie en forme de couche qui est élaborée au moyen du processus de moulage à partir d'un mélange de réaction au polyuréthanne, et une seconde partie en forme de couche qui adhère à ladite première partie pour former le composite.

Title: Process for high-load treatment of carbohydrate-containing waste water
IPC: C02F3/02
Filed: 1989-10-18
Abstract: (1) A process for high-load treatment of carbohydrate-containing waste water comprises the steps of separating a yeast appearing in the waste water, subjecting the separated yeast to large-quantity culture, and treating the waste water by a high-load operation using the cultured yeast as a seed fungus under the conditions of a volume load of 10 to 80 kg-BOD/m3 day and a yeast load of 1.0 to 5.0 kg-BOD/kg-yeastday, whereby it is possible to treat the high-concentration waste water efficiently with a small volume for treatment.  The quantity of air required of a diffuser system blower may be 0.15 to 0.60 kg-O2/kg-BOD-removed, the value being 1/3 to 2/3 times that in a general activated sludge method.  A pH of not more than 5.0 and a residence time of at least 1.5 hours may be employed.  To obviate the conflict between the yeast and bacteria, it is recommendable to add C?2 to a reservoir in an amount of 10 to 50 mg/?.  If it is impossible to add C?2 to the reservoir, the C?2 may be added to a yeast tank in the same amount as above-mentioned.  This process, when carried out under the conditions mentioned above, promises an increase in the efficiency of the plant for treatment of the carbohydrate-containing waste water.  Upon the treatment of the waste water, a surplus of yeast is generated, which contains (2) proteins and vitamines in high contents and, therefore, is capable of being taken by a fodder company as fodder or fertilizer; thus, the disposal cost associated with the surplus yeast is saved.  On the other hand, an about 20% portion of the influent BOD, which is left upon the treatment with yeast, requires an after-treatment, so that an expense is necessary for disposal of the sludge formed. The disposal cost required in this case, however, is as low as about 1/4 times that required in the general activated sludge method, and the disposal cost for the after-treated sludge is substantially negligible because it can be canceled by selling the surplus yeast as fodder or fertilizer, as mentioned above.  Thus, the process for high-load treatment of carbohydrate-containing waste water promises a marked reduction in the treatment cost for the waste water.

IPC: H04N5/335
Filed: 1989-11-09
Abstract: A signal processing circuit of a solid-state imaging device having an image pickup section formed by plural solid-state image sensors including a discrete pixel array is disclosed. The solid state image sensor for green-color image pickup is arrayed in the image pickup section with a spatial shift equal to one half the pixel pitch from the solid-state image sensors for red-color image pickup and the solid-state image sensors for blue-color image pickup in accordance with the spatial pixel shifting method.

Abstract: ABSTRACT OF THE DISCLOSURE A method  is  described  for  achieving  selective generation of thermal energy from a thin metal film upon exposure to microwave energy.   A deactivating material is first applied to a substrate from the thin metal film in a pattern corresponding to the region from which heat is not to be generated.  The metal then is applied over the  substrate  and the  pattern  in  a  thickness  which normally  generates  thermal  energy  upon  exposure  to microwave energy.  Such thermal energy is produced only from those regions where the metal is adhered directly to the substrate.

IPC: H04Q3/68
Filed: 1990-05-18
Abstract: A method of expanding a regular three-stage switching array. Original switching blocks of the first and third stages having a smaller number of crosspoints are enlarged to switching blocks having a larger number of crosspoints, by combining the original switching blocks. In addition, the three stages are expanded by adding additional switching blocks. After the enlarged blocks are formed, at least one additional block is added to the second stage, and some of the connection paths between the enlarged blocks and the blocks of the second stage are rerouted to the additional blocks. The rerouting is performed for the original blocks of the second stage one at a time. In order to avoid disruption of operations during the expansion, while the rerouting is being performed for any particular original block of the second stage, the connections between that original block and the enlarged blocks which would otherwise be established, are switched through redundant connection paths in the second stage. When the rerouting for the original block is complete, these connections are switched back to the connection paths of the original and added blocks of the second stage. After repeating the above for all original blocks of the second stage, the outputs of additional blocks of the first stage and the inputs of additional blocks of the third stage are respectively connected with the inputs and outputs that are still free in the now existing original and additional blocks of the second stage.

The antenna may also include a plurality of polarizing antenna elements carried by the slot-forming means adjacent at least one or two of the substantially concentric, annular slots to enhance the unidirectional sensitivity of the antenna. Such a plurality of polarizers may be carried by the slot-forming means in a plurality of locations spaced above and over at least one or two of the concentric annular slots and oriented and distributed around their peripheries at locations to correct for variations to polarity and to suppress cross-polarization to and from the antenna.
