Abstract: A thermal spray material comprising granules containing a rare earth oxyfluoride has a particle diameter of 1 to 150 ?m at a cumulative volume of 50 vol % before ultrasonic dispersion and 10 ?m or smaller after ultrasonic dispersion at 300 W for 15 minutes as determined by laser diffraction/scattering particle size distribution analysis. The particle diameter after ultrasonic dispersion is one-third or less of that before ultrasonic dispersion. The thermal spray material has an average aspect ratio of 2.0 or lower and a compressibility of 30% or less. When the granules further contain a rare earth fluoride, upon being analyzed by X-ray diffractometry using Cu-K? or Cu-K?1 radiation, S1/S2 is preferably ?0.10. S1=intensity of the maximum peak assigned to the rare earth oxyfluoride. S2=intensity of the maximum peak assigned to the rare earth fluoride, both observed in a 2? angle range of 20° to 40°.

Abstract: An A/D converter includes a sampling capacitor that accumulates a charge according to an input voltage, a first initialization switch that initializes the sampling capacitor, a sample hold switch that switches a connection state of an external input terminal and the sampling capacitor, and a second initialization switch that initializes a charge accumulated in an input node via a resistor, the input node connecting the external input terminal and the sample hold switch.
