Abstract: A heat-shielding film formed on the wall surface of a metal base material contains a plurality of ceramic hollow particles (1) and metal phases (2) to which the plurality of ceramic hollow particles (1) are joined at points. Each of the plurality of ceramic particles (1) is joined at a point, through the metal phase (2), to another ceramic particle among the plurality of ceramic particles (1) so that the plurality of ceramic particles (1) are joined to each other. The plurality of ceramic hollow particles (1) of the heat-shielding film (10) and the wall surface are joined at points to the metal phases (2) so that the plurality of ceramic hollow particles (1) are joined to the wall surface.

Abstract: A DC to DC converter includes an inductor having a first terminal and a second terminal, the first terminal coupled to an input of the DC to DC converter and the second terminal being coupled to an output of the DC to DC converter. A first switch is coupled between the second terminal and a current sensor. The switch controls current flow through the inductor and generates an inductor current signal representative of the current flow through the sensor. A slope generator generates a slope compensation signal. A first mixer adds the slope compensation signal to the inductor current signal. A sample and hold circuit samples a portion of the slope compensation signal. A second mixer subtracts the sampled portion of the slope compensation signal from the output of the first mixer, wherein inductor charging is terminated in response to the output of the first mixer.
