  • Patent number: 6365206
    Abstract: Paste-form natto which has a comfortable feeling on the tongue and has little or none of the undesired properties of viscous thread, odor and bitterness of ordinary natto, and a method of producing it in which dried soybeans are dehulled and the kernels sliced to 0.1-5 mm thickness and soaked in 1.0-2.5 times their weight in water, steamed, and lumps of steamed soybean flakes are decomposed during or before seeding with commercial [Bacillus nattol] Bacillus natto. The seeded soybean flakes are fermented aerobically, aged in a chilled room to produce paste-form natto, which had a good feeling on the tongue, does not have the viscous thread, odor and bitterness of ordinary natto. The paste-form natto is packed in plastic or edible containers of any size, chilled or frozen, and shipped to food processing plants. The packed and frozen paste-form natto is not contaminated by micro-organisms and is sanitary.

  • Patent number: 6359616
    Abstract: A coordinate input apparatus for correcting the shift in an input coordinate system between different coordinate input apparatuses relative to an opening of each apparatus. A data processing block captures information from a coordinate detector PD to determine whether a tapping operation has been performed and determine whether the finger is being slid on a sensor board. A data analyzing block compares inputted absolute coordinates (X, y) with minimum coordinate values (Xmin, Ymin) and maximum coordinate values (Xmax, Ymax) indicative of a preset effective pointing area on the sensor board. A control block controls the data analyzing block to transfer replaced minimum coordinate values (Xmin, Ymin), maximum coordinate values (Xmax, Ymax) and the values of absolute coordinates (X, Y) to a data correcting block. Based on these minimum coordinate values (Xmin, Ymin) and maximum coordinate values (Xmax, Ymax), the data correcting block transforms the absolute coordinates (X, Y) into display coordinates.

  • Patent number: 5781181
    Abstract: A coordinate detection system capable of displaying relevant coordinates when operated with only one fingertip or like coordinate designator even during a repeat operation of the latter with no complicated designator manipulations required. The system comprises a coordinate detection apparatus and a coordinate output apparatus. The coordinate detection apparatus includes a sensor substrate to be operated by the coordinate designator, scan driving output units for generating a detection signal in response to the coordinate designator operation, and signal processing units for extracting tap and slide component data from the detection signal and supplying the extracted data to the coordinate output apparatus.
