Abstract: A sealing bag includes a valve 3 which is fitted to a bag body and which communicates interior and exterior of the bag body with each other. A ball valve element 5 of the valve 3 is placed in a tapered passageway 8 so as to be advanceable toward and retreatable from the interior side of the bag body, and can close the tapered passageway 8. A screw type cap 6 of the valve 3, which is fitted to a fitting hole 27 of a valve body 4 so as to be advanceable toward and retreatable from a smaller-diameter end portion of the tapered passageway 8, has a stopper portion which is to be inserted into the fitting hole 27 and contactable with the ball valve element 5.

Abstract: A structure of an air passage of a sealable bag is provided wherein bag sheets 11, 12 and a valve body sheet 31 layered between the bag sheets 11, 12 are used. The valve body sheet 31 comprises a front piece 31a and a rear piece 31b, and a air passing space is formed between the front bag sheet 11 and the front piece 31a, as well as between the rear bag sheet 12 and the rear piece 31b, while a dead-end space is formed between the front piece 31a and the rear piece 31b. In said valve body, at one side based on the direction of flow of air in the air passage 3, said dead-end space is closed by said front piece 31a and rear piece 31b that are joined together, while on the other side, said dead-end space is opened by said front piece 31a and the rear piece 31b that are separated from each other.

Abstract: A packaged product formed by enclosing a content material, such as food or beverage, sanitary products or medical products, within a packaging material including at least a layer of hydrophilic resin, is heat-treated with hot water for, e.g., boil sterilization or retort sterilization. The hot water is caused to contain a water-soluble compound in an amount substantially exceeding a level contained in tap water, whereby it becomes possible to suppress the opalescence of the packaging material causing inferior appearance or transparency and leading to a lowering in gas-barrier property, which has been problematic in the conventional boil or retort hot water treatment.

Abstract: In failure analysis method of a semiconductor memory device, an absolute value of a position difference between two fail bits of a two-dimensional bit map is calculated while a histogram corresponding to the absolute value of the position difference is updated. The bit map indicates a map of fail bits and each fail bit corresponds to a fail memory cell. The above calculation is repeated to all combinations of two of the fail bits in the bit map. Then, an expectation function value is calculated for each of values from the histograms and the number of the fail bits. Finally, whether the fail bits has regularity or irregularity for each value is determined based on the calculated expectation function value for the value.
