    摘要： A wafer test method of a power switch wherein a main IGBT and a current detecting IGBT that detects a current value of the main IGBT are integrally formed on the same semiconductor substrate is such that there is provided resistance means that causes an emitter current of the current detecting IGBT to flow through an emitter terminal of the main IGBT, the main IGBT and current detecting IGBT are energized simultaneously, thereby applying a constant current to a common collector terminal of the main IGBT and current detecting IGBT, and a current ratio (main current/detected current) between a main current of the main IGBT and a detected current of the current detecting IGBT is calculated from the current flowing through the current detecting IGBT, obtained from the voltage across the resistance means, and the constant current.

    摘要： The optical image stabilizer shifts an image stabilizing element with respect to an optical axis of an optical system to reduce image shake. The stabilizer includes a lock ring which is rotatable to a lock position to limit shift of the image stabilizing element and to a lock-releasing position to allow the shift of the image stabilizing element, an actuator which rotates the lock ring to the lock position and the lock-releasing position, and a biasing mechanism which mechanically biases the lock ring rotated to the lock position toward the lock position and biases the lock ring rotated to the lock-releasing position toward the lock-releasing position.

In the case of 100 moles of barium titanate, there are 0.1 to 3 moles of the first accessory constituent, 2 to 10 moles of the second accessory constituent, 0.01 to 0.5 moles of the third accessory constituent, 0.5 to 7 moles of the fourth accessory constituent (wherein the number of moles of the fourth accessory constituent is that of R1 alone), more than 0 but not more than 5 moles of the fifth accessory constituent, and more than 0 but not more than 9 moles of the sixth accessory constituent.
