  • Patent number: 11139761
    Abstract: A control apparatus includes a controller that controls a motor, a first transmission channel connected to a first power-supply terminal of an alternating-current source that supplies an alternating-current voltage, a second transmission channel connected to a second power-supply terminal of the alternating-current source, and a third transmission channel connected to each of the first transmission channel and the second transmission channel. The controller switches the rotational speed of the motor based on the voltage value of a signal input to the controller in accordance with a first connection status of the first transmission channel and the third transmission channel and a second connection status of the second transmission channel and the third transmission channel.

  • Patent number: 8680301
    Abstract: There are provided foods and beverages that will suppress the absorption of dietary lipids, thereby suppressing the rise of triglyceride in blood. High-molecular weight polyphenol fractions recovered from oolong tea are added to foods or beverages as an active ingredient for inhibiting lipase activity. The foods and beverages of the present invention are safe and their inherent flavor has not been impaired; hence, they may be taken in routinely so that the lipase inhibitory action of the high-molecular weight polyphenol fractions will suppress the rise of triglyceride in blood and prevent obesity.

  • Patent number: 8388539
    Abstract: Surgical operation supporting apparatus and method is disclosed in which based on a high-definition tomographic images of an operation site produced before surgery, a three-dimensional model of the operation site is generated, and a surface of the operation site is optically measured during the surgical operation, and further, first position information that represents a three-dimensional position of each of points on the surface is acquired. An unexposed portion of the operation site is measured with ultrasonic waves during the surgical operation, and second position information that represents a three-dimensional position of each of points in the unexposed portion is acquired. Based on the first position information and the second position information, displacement and distortion at a portion whose three-dimensional position is not known in the three-dimensional model is estimated to obtain an estimated result.

  • Patent number: 8112144
    Abstract: Since cerebral atrophy does not occur only in a specific cross-section and reaches the brain in its entirety or arises prominently in a specific lobe (for example temporal lobe), for the assessment of cerebral atrophy, not only atrophy assessment for the frontal lobe but also an assessment also including atrophy of the temporal lobe, the parietal lobe and the occipital lobe is more desirable. The intracranial volume, the volume of the grey matter and the volume of the white matter are respectively extracted, computed and converted into numbers by image processing from a plurality of MRI slice images and the like. Ratios of these values from the conversions into numbers are taken to calculate the ratio of the grey matter and the ratio of the white matter with respect to the entire brain. Through comparison of a multitude of measurement data obtained by this automated computation, and a case, an objective cerebral atrophy assessment is carried out.
