  • Patent number: 10773311
    Abstract: An object of the present invention is to provide a phosphorus-containing copper powder with good volume resistivity and a small carbon content by suppressing an oxygen content to a relatively low value even if a particle size is made small, and a method for producing the same. In the phosphorus-containing copper powder containing phosphorus, a ratio of an oxygen content (wt. %) to a BET specific surface area (m2/g) (oxygen content/BET specific surface area) is 0.90 wt. %·g/m2 or less, a divalent copper compound is present on a surface of particles constituting the phosphorus-containing copper powder, a carbon content is 0.10 wt. % or less, and D50 is 7.11 ?m or less.

  • Patent number: 7825786
    Abstract: The vehicle state value detecting device includes a first low pass filter (32, 36) and a second low pass filter (33, 37) having a lower cutoff frequency than the first low pass filter. The device processes a detection signal of a sensor (10, 11) for a motion control of a vehicle such as a yaw rate sensor and a lateral G sensor by selectively using one of the two low pass filters. A signal selecting unit (35, 39) selects the output of the first low pass filter when the control process demands prompt detection of an abrupt changes in the behavior of the vehicle and the output of the second low pass filter when it is not the case and an enhanced stability of the control action has a priority.

  • Patent number: 6925657
    Abstract: A head protecting body for a safety helmet, in which a first liner member for an impact-on-the-head absorbing liner includes a swell for reinforcing at least one region of a forehead region, a left temple region, a right temple region and an occiput region in an overlapping region with respect to a second liner member having a density lower than that of the first liner member, on an overlapping surface side of the first liner member, and the second liner member includes a hollow having a shape substantially corresponding to the swell. According to this head protecting body, despite that the impact-on-the-head absorbing liner is not broken easily more than necessary near a region reinforced with the reinforcing swell, both the maximum acceleration during impact and an HIC can be decreased effectively.
