    摘要： An optical power measuring apparatus for measuring a power level of an optical signal comprised of a light intensity modulated signal, received by a light receiving element is provided. In the apparatus, a first signal path including a first voltage detection circuit and a first amplifier circuit supplies a processor with a first signal having a voltage proportional to a current flowing through a light receiving element (PD), and a second path including a TIA, a DC detection circuit and a second amplifier circuit supply the processor with a second signal. The second signal corresponding to an envelope of a voltage from the TIA. The processor compares the level of the first signal with a predetermined set value to select an optical power value retrieved based on the first signal when the level of the first signal is equal to or higher than the set value, and to select an optical power value retrieved based on the second signal when lower than the set value, and outputs the selected optical power value as a measured optical power value Pout. An output signal of the TIA can be supplied to an external device, so that the optical power measuring apparatus can measure an optical power level while serving as an optical signal receiving apparatus.

    摘要： A balloon expandable superelastic stent is made of a Ti—Ni—Nb (the content of Nb being at least 3 at %) shape memory alloy. A shape recovery temperature of the stent is lower than a living body temperature in an unloaded state after shape memory treatment. The shape recovery temperature exceeds the living body temperature after the stent is mounted to a catheter and released from the catheter in a living body.

    摘要： Provided is a core wire for guide wire in which high rigidity can be attained even with a fine wire diameter so that pushability is improved while the core wire is prevented from fatigue deformation, and a method for manufacturing the core wire.This core wire 15 for guide wire is made of a Ti—Ni based alloy and has a wire diameter not larger than 0.5 mm and a Young's modulus not lower than 50 GPa. According to the manufacturing method, first, wire drawing is performed on a raw material M0 so that the raw material M0 is passed through a wire drawing dice 2 to be drawn to a certain length while the wire diameter of the core wire is reduced. Thus, a primary processed material M1 is formed. After that, the primary processed material M1 is hammered and drawn by swaging dices 5 and 5 so that a secondary processed material M2 is formed. In this manner, the core wire 15 having a wire diameter not larger than 0.5 mm and a Young's modulus not lower than 50 GPa is manufactured.
