  • Patent number: 12001339
    Abstract: According to one embodiment, a dictionary buffer stores dictionary data including a first substring and data before the first substring. A substring generator generates, from second input data, second substrings. A transformer transforms each of the second substrings into a hash value. A read processor reads the dictionary data, using a hash value transformed from a third substring among the second substrings. An acquisition unit compares a data string including the third substring and data before the third substring with the read dictionary data, and acquire first and second match lengths of the third and fourth substrings. A coded data generator generates coded data based on the acquired first and second match lengths.

  • Patent number: 10661609
    Abstract: A recessed portion is formed in each tire side portion of an agricultural machinery pneumatic tire. Rigidity at the part of each tire side portion where the recessed portion is formed is reduced. This enables each tire radial direction outside portion to be made to tilt over toward tire width direction outside with the recessed portion as a point of origin without reducing the internal pressure, enabling the ground contact width of a tread portion to be enlarged. Since there is no need to intentionally reduce the internal pressure in order to reduce the ground contact pressure, bead portions do not tilt over more than necessary, and there is no reduction in the durability of the bead portions.
