  • Patent number: 8585615
    Abstract: An abdomen width determiner determines an abdomen width of a subject. A shape index calculator calculates a shape index corresponding to a cross-sectional shape of an abdomen of the subject. An obesity evaluator evaluates whether an obesity degree of the subject is high or low. An obesity index calculator calculates an obesity index corresponding to the abdomen width using a first equation if the obesity evaluator evaluates that the obesity degree is low, and calculates an obesity index corresponding to the abdomen width and the shape index using a second equation different from the first equation if the obesity evaluator evaluates that the obesity degree is high.

  • Patent number: 7594896
    Abstract: An abdomen width determiner determines an abdomen width value of a human subject. A memory stores a correlation between abdomen width values and waist circumferences of human beings. A waist circumference calculator calculates a waist circumference of the human subject on the basis of the abdomen width value determined by the abdomen width determiner and the correlation stored in the memory. The correlation stored in the memory may be expressed by the following regression formula: Y=aX+b where “Y” is a waist circumference of a human being, “X” is an abdomen width value of a human being, and “a” and “b” are constants.

  • Patent number: 7592263
    Abstract: A method of manufacturing a semiconductor device. In this method, a concave portion is formed in one surface in the thickness direction of a primary base plate comprising a semiconductor substrate with a relatively large thickness dimension. Then, through-holes are formed by a reactive-ion etching process using as a mask an opening formed in an oxide film provided on the other surface in the thickness direction of the primary base plate. The opening has a narrow width in a region corresponding to the concave portion and a wide width in the remaining region. Thus, respective times necessary for the wide-width through-hole to penetrate through the primary base plate and necessary for the narrow-width through-hole to reach a bottom surface of the concave portion can be approximately equalized to complete the common etching process of the wide-width through-hole and the narrow-width through-hole approximately simultaneously.
