  • Patent number: 6358494
    Abstract: A composite toothpaste product comprising a toothpaste containing a hydroxyapatite as a main active ingredient and another toothpaste containing a fluorine compound as a main active ingredient, which are enclosed with a container made of, for instance, a flexible tube but separated from each other by a partition united to the container. In the composite toothpaste product, the toothpastes are separated from each other with no contact when it is out of use, and are squeezed out of the container, when in use, in such a manner that the latter toothpaste is enclosed with the former. It is far more effective in removing bacterial plaque, improving tooth whiteness, and preventing dental caries than the conventional toothpaste products containing only either a hydroxyapatite or a fluorine compound.

  • Patent number: 4879503
    Abstract: A blower motor control for an air conditioner is carried out so that when a detected actual rotation speed has come into an allowable deviation range to a target rotation speed at the time of controlling the motor so as to approach its rotation speed to the target rotation speed, the output for adjusting the rotation speed is not changed. As a result, a stable rotation speed can be obtained as long as the load on the motor does not fluctuate. Furthermore, after the output has been fixed, the allowable deviation range is expanded to prevent the output from changing even if slight load fluctuation is caused. This allows stable controls.

  • Patent number: 4451235
    Abstract: An artificial dental root comprised of a particulate or powdered form of synthetic hydroxyapatite or calcined or sintered synthetic hydroxyapatite or a mixture thereof and an organic matrix, the surface area of said artificial dental root to be brought into contact with a bone being composed of both a phase of said hydroxyapatite and a phase of said organic matrix. The artificial dental root is prepared by blending said hydroxyapatite with said organic matrix and molding the blend. The artificial dental root has moderate affinity for a bone and high mechanical strength.
