摘要： A DC-DC converter converts a DC input to a predetermined high-voltage DC output according to a predetermined control signal. An output unit has a pair of high- and low-voltage-side output paths and supplies the predetermined high-voltage DC output to a load. An output variation detecting unit has a resistor voltage dividing circuit including high- and low-voltage-side resistors connected in series between the pair of output paths and detects a variation in predetermined high-voltage DC output that follows a variation in the load. An inner shield shields the exterior of the resistor voltage dividing circuit. The inner shield is electrically connected to a node of the high- and-low voltage-side resistors. An outer shield shields the exterior of the inner shield. The outer shield is electrically connected to the low voltage-side output path of the pair of output paths. A control unit receives a voltage component generated across both ends of the low-voltage-side resistor of the resistor voltage dividing circuit, generates the predetermined control signal in accordance with the voltage component, and supplies the predetermined control signal to the DC-DC converter.

摘要： A PC board inspecting method capable of detecting deviation of an IC component at high speed with small storage capacity utilizes inspection logic particular to a component to be inspected. The inspection logic includes a color condition for specifying a color appearing in the body of the component to be inspected. The component is radiated with a plurality of color rays at different angles of incidence. An image formed by reflection light of the color rays is captured, and an inspection image including at least part of an edge of the body of the component to be inspected is captured. By using the color condition, a component body area satisfying the color condition is extracted from the inspection image by an image process.

摘要： A cover member of an ultrasonic sensor has a first engagement portion and a second engagement portion, which are respectively engaged with a third engagement portion and a fourth engagement portion of a sensor body. The engagement portions are arranged in such a manner that a force applied to the cover member due to an engagement between the first engagement portion and the third engagement portion and a force applied to the cover member due to an engagement between the second engagement portion and the fourth engagement portion respectively have opposite directions to be substantially countervailed when the sensor body is attached to the cover member. Thus, the cover member can be restricted from slanting when the sensor body is fixed to the cover member.
