Abstract: A nonvolatile semiconductor storage device has floating-gate memory cells and a memory control circuit which controls them. During programming operation of the memory cells, the memory control circuit makes the potentials at the backgate and source of the memory cells equal. For example, during programming operation of the memory cells, the memory control circuit short-circuits together the backgate and source of the memory cells. For another example, during programming operation of the memory cells, the memory control circuit switches from a state where the potentials at the backgate and source of the memory cells are equal to a floating state.

The gate electrode extends beyond a boundary portion between the channel region and the element isolation region. A width of the first region is smaller than a width of the second region in a channel width direction of the first region and the second region.

Abstract: A process for producing a modified coal from a coal of low-rank as a raw material includes dehydrating the coal, adding water to the dehydrated coal, agglomerating the water-added coal, and gradually oxidizing the agglomerated coal. In the water addition, an added amount of the water is regulated so that the water-added coal has a water content of 5% by mass or more and 20% by mass or less. In the oxidation, the agglomerated coal is held in an air at a temperature of 70° C. or more and 105° C. or less.

Abstract: A method for producing modified coal using coal of a low grade comprising: adding water for preventing any dust generation to the dewatered coal; an addition amount of the water is adjusted for a water content rate of the water-added coal to be 6% by mass or more to 16% by mass or less; agglomerating the water-added coal; slowly oxidizing the agglomerated coal; and crushing the oxidized coal.

Abstract: A method for storing upgraded coal, which is economical and whereby it becomes possible to prevent the spontaneous ignition of piles; and grain-size-controlled coal which rarely undergoes spontaneous ignition during storage. The method for storing upgraded coal includes piling up granular coal containing upgraded coal, wherein the content of grains each having a grain size of 10 mm or less in the coal is 50 mass % or more. It is preferred that the content of grains each having a grain size of 1 mm or less is 25 mass % or more and the content of grains each having a grain size of 0.15 mm or less is 7 mass % or more in the coal.

Abstract: The present invention provides microsphere manufacturing method and apparatus capable of stable obtaining microspheres of a desired size and reducing facility cost. According to the method and the apparatus, to manufacture microspheres made of a second liquid in a first liquid, the first liquid is supplied into a first channel to flow therein and the second liquid is supplied to an intermediate part of the first channel through a second channel. The supply velocities of the first and second liquids are set such that the second liquid closes the first channel and the closing part of the second liquid is cut off due to a pressure difference between an upstream side and a downstream side to form microspheres.
