Abstract: A leaf spring frame member (50) comprises: a plurality of leaf spring product parts (11A) each of which includes an outer frame part (11a), an inner frame part (11b) and spring parts (11c); and a support frame (51) which is arranged around the leaf spring product parts (11A) and supports the leaf spring product parts (11A). Each of the leaf spring product parts (11A) and the support frame (51) are connected to each other by connection parts (52). A breaking region (53), which is breakable, is formed in the connection part (52). An outer edge (53a) of the breaking region (53) is situated on the inside of an outer edge (11h) of the leaf spring product part (11A).

Abstract: There is provided a leaf spring which can prevent a reduction in the spring strength and can also prevent a reduction in the electrical conductivity when the thickness of the leaf spring is decreased. The leaf spring includes an outer frame portion an inner frame portion 5b, 11b disposed inside the outer frame portion 5a, 11a, and spring portions provided between the inner frame portion and the outer frame portion The leaf spring is made of a Cu-based alloy, and has an electrical conductivity of not less than 8% IACS and a 0.2% proof stress of not less than 900 MPa.

Abstract: A color conversion section for an imaging device carries out conversion to imaging data imaged by each medical imaging device for eliminating differences in color property of each imaging device, and generates standard color graphic data. To this standard color graphic data, a color conversion section for highlighting a specific tissue carries out color conversion for highlighting a designated specific biotissue, such as a blood vessel, to generate specific tissue highlighted graphic data. To this specific tissue highlighted graphic data, a color conversion section for a monitor carries out conversion for eliminating differences in color property of each monitor to generate display data. Color monitors display graphics based on this display data.
