Abstract: Objects of the invention are to minimize power consumption while maintaining the required information processing capabilities of an LSI chip by supplying multiple voltages to the LSI chip such that its circuit blocks receive necessary voltages and to prevent an increase in the chip area of the LSI chip and performance degradation of signal wires, which may result from the supply of the multiple voltages, by reducing the number of power supply wires. In an LSI chip to which two voltages are supplied, high voltage wires are more densely spaced than low voltage wires. By selectively applying voltages based on circuit block performance, it is possible to reduce power consumption while maintaining the amount of information processed by the LSI chip.

Abstract: A catheter assembly (1), including an outer catheter (2) and an inner catheter (6) capable of being inserted into the outer catheter (2). The catheter assembly is characterized in that an outer catheter hub (5) and an inner catheter hub (9) are fixedly fitted to each other so that the two catheters are not rotated nor moved relative to each other, and when fitted to each other, at least a part of the tip of the inner catheter (6) is protruded by 10 mm or shorter from the tip of the outer catheter (2). When the inner catheter is inserted into the outer catheter, operabilities such as kink resistance, press-in performance, and torque transmission performance are excellent and the inner diameter thereof is increased when the catheter is used after indwelling. As a result, the range of choices of a catheter for treatment can be increased.
