Abstract: There is provided a metallic glass component with its surface layer having both durability of a film and chromatic color properties, and a method for forming the surface layer. Surface active treatment is performed wherein the surface of the metallic glass component is reacted with a mixed aqueous solution of nitric acid and hydrofluoric acid to remove an oxide film and to provide an anchor bond shape on the surface of a metallic glass component, and electroplating or electroless plating is then performed, to form a plating film on the surface of the metallic glass component. It is thereby possible to form a surface layer of a metallic glass which has both durability and a chromatic color.

Abstract: An ultrasonic diagnostic apparatus according to the present invention includes: a transmitting section 102 that drives an ultrasonic probe to transmit an ultrasonic wave toward a measuring region of a subject including an arterial vascular wall; a receiving section 101 that receives a reflected wave, produced by getting the ultrasonic wave reflected by the subject, at the ultrasonic probe to generate a received signal; a movement information deriving section 110 for deriving information about at least the axial movement of the arterial vascular wall based on the received signal; and a boundary locating section 109 for locating at least one of the blood flow-intima boundary, the media-adventitia boundary and the adventitia-body's connective tissue boundary of the arterial vascular wall in the measuring region based on the movement information.

Abstract: A superconducting quantum interference fluxmeter, a super-high-sensitivity fluxmeter using a SQUID, suitable for use in precision electric instrumentation and superconducting electronics. The fluxmeter comprises a system to detect response output from the SQUID with high sensitivity by applying thereto such exciting AC as has a plurality of frequency components from an excitation AC source, and a system to detect with high sensitivity such alternating current as has higher or lower harmonic component of the exciting AC, which is generated by utilizing electromagnetic nonlinearity of the SQUID. Thus this invention markedly relieves difficulties in the manufacture and the use of the superconducting quantum interference devices, and enables selection of any desired operating temperature range, and compensation of quality changes with time.
