Abstract: A semiconductor memory cell is configured using a sense amplifier and a memory cell containing MOS transistors. In a write cycle, the sense amplifier inputs write data to accumulate charges in the memory cell. In a read cycle, the sense amplifier outputs read data in response to the charges accumulated in the memory cell. A cell array is configured using sense amplifiers and memory cells, which are arranged in a matrix form in such a way that each sense amplifier is connected with the memory cells which are arranged in a same column. In addition, a pair of a write word line and a read word line are shared by the memory cells which are arranged in a same row, while a pair of a write bit line and a read bit line are shared by the memory cells which are arranged in a same column. Further, the sense amplifier is connected with the pair of the write bit line and read bit line. The write word line is arranged between the read word line and a ground line having a ground level.

Abstract: A treated waste has been treated so as to prevent diffusion of a substance to be disposed, of e.g., radionuclide “I”, that tends to occur when the waste is disposed of in reducing environment at an ultra-deep underground. The treated waste has a low-resolution compound containing “I”, e.g., “AgI”, and a high oxygen potential agent having a higher oxygen potential than the compound, e.g., “Fe2O3”. Ionization of the substance to be disposed, attributable to reduction of the compound, can be suppressed over a long time.

Abstract: A digital information reproducing apparatus in accordance with a prior art that uses a semiconductor memory to realize a memory means cannot reproduce digital data which has been encoded according to a compression coding form different from the one adopted by an incorporated decoding circuit. According to the present invention, a decoding program stored in a second semiconductor memory is selected according to a compression coding form adopted for digital data stored in a first semiconductor memory. The selected decoding program is used to decode the digital data by means of an arithmetic circuit. Thus, digital information can be reproduced irrespective of a compression coding form adopted for provided digital information.

A switching device selects one of an address with which the memory is randomly accessed and the address produced by the address producing device. Data is written into and read from the memory, at a location that corresponds to the address that is selected by the switching device and supplied to the memory.

Abstract: A system and method for treating farm animal waste, such as hog and poultry waste, to remove volatile organic compounds (VOCs) from wastewater treatment pits and thus control smell is disclosed. The farm animals are housed in structures equipped with grated flooring to permit animal waste to fall into pits or reservoirs below. The pits contain water inoculated with a special assemblage of natural microbes to which oxygen is supplied through piping arranged in the pits. These special microbes have an affinity for ammonia and convert much of the animal waste into carbon dioxide, fatty acids, and water. The system also includes a second piping network situated beneath the grated flooring which serves to create a negative air situation by which escaping foul-smelling air is pulled back into the wastewater to permit further action on the VOCs by the microbes in the water.
