  • Patent number: 7613596
    Abstract: A tire profile (12) includes a tread (16), a shoulder (18), a flat portion (20), an upper sidewall (22) and a lower sidewall (24). The shoulder (18) is provided in contact with a tread (16) at a point (Pa). The flat portion (20) is provided in contact with the shoulder (18) at a point (Pb). The upper sidewall (22) is provided in contact with the flat portion (20) at a point (Pc). A system including an input portion and a calculating portion is used for designing the profile (12). When the numeric values of a radius of curvature (R1) of the shoulder (18) and an inclination angle (?) of the flat portion (20) are input by the input portion, the calculating portion calculates a length (L) of the flat portion (20) and a radius of curvature (R2) of the upper sidewall (22). Based on the input numeric values and the calculated numeric values, the profile (12) is drawn by CAD software.

  • Publication number: 20080235901
    Abstract: In a suctioning state, even if the amount of dust trapped in a dust collecting unit in a main air passage is increased, air suctioned from a hose connection port is branched into a first half passage and reduction in the suction air amount can be suppressed. When the suctioning state is switched to a dust moving state by switch means, the dust trapped in a pleated filter is moved to the dust collecting unit, increase in the air passage resistance at the first half passage side caused by clogging of the pleated filter can be suppressed, and reduction in suction power over time can be suppressed. Since an upper air passage and lower air passage are provided in the lid body, the dust collecting unit is exposed with the lid body opened, whereby maintenance performance of the dust collecting unit is improved.

  • Publication number: 20080168616
    Abstract: A pleated filter is provided higher than an upper opening of a dust collecting unit. An introduction hole is provided on the downstream side of the pleated filter. When switching to a dust moving state, the outside air introduced from an introduction hole spreads to the entirety of the pleated filter when passing through the pleated filter and evenly cleans dust adhering to the entirety, and when micro dust removed from the pleated filter is moved to the dust collecting unit, this movement is supported by gravity by using the weight of micro dust. The pleated filter is prevented from being clogging by reliably moving micro dust removed from the pleated filter to the dust collecting unit, and when switching to a suctioning state, a suction air amount to pass through the first air passage is secured, whereby reduction in suction power over time can be suppressed.

  • Patent number: 7366578
    Abstract: Typical numeric data for specifying a shape of a first product having a typical size are stored in a storage portion. By an input portion (10), a size of a second product other than the typical size is input. A calculating portion (4) determines recommended numeric data for specifying a shape of the second product based on the size of the second product and the typical numeric data. By the input portion (10), furthermore, corrected numeric data for the recommended numeric data are input. The calculating portion (4) decides the validity of the corrected numeric data. In the case in which the corrected numeric data have the validity, the calculating portion (4) determines final numeric data for specifying the shape of the second product based on the recommended numeric data and the corrected numeric data. Based on the final numeric data, the shape of the second product is drawn by CAD software.

  • Patent number: 7353150
    Abstract: First of all, size data (MD), (BD), (BH) and (MW) of a tire are input. Next, a ratio (b/a) of a major axis radius (b) to a minor axis radius (a) of an ellipse (18) is input. Then, constants (S), (a) and (b) of an involute function are calculated. Based on the involute function having these constants, a profile function (22) from a central position in a lateral direction to a maximum width position is determined over an X-Y plane. Subsequently, the profile curve (22) is divided into a large number of segments. Next, each of the segments is caused to approximate to a circular arc. In the approximation, a radius of curvature is determined in such a manner that the adjacent circular arcs are tangent to each other. Thus, a profile is designed.
