    Abstract: A DCDC converter module is provided that includes an insulating substrate having first and second surfaces; and a circuit section at the insulating substrate. The circuit section includes a switching element and an output filter connected to the switching element in series from an input end to an output. The output filter has an output inductor, and first and second output capacitors connected in parallel to each other and having different capacitance. A current path from the switching element to the output end of the circuit section penetrates through the insulating substrate from the first surface to the second surface. The first and second output capacitors are different from each other in position in a thickness direction and are arranged to the current path. An inductor component is between a plus terminal of the first output capacitor and a plus terminal of the second output capacitor.

    Abstract: An optical device includes a protective cover and a driver. An outer surface of the protective cover includes a first region having higher hydrophobicity than a second region. The first region is separated from the second region by a first boundary line extending from a starting point deviating from a center point of the protective cover in the direction toward an outer edge portion of the protective cover and a second boundary line extending from the starting point in the direction toward the outer edge portion of the protective cover, and which is located on a side where the center point is not included. Among angles defined by the first and second boundary lines, an angle on the side where the center point is not included is equal to or less than about 180°.

    Abstract: An optical unit includes an optical sensor, a protective cover disposed in a direction of view from the optical sensor, an actuator to drive the protective cover, and a casing including a space between the casing and the protective cover and to which the optical sensor and the protective cover are attached. A first region on the casing adjacent to an outer edge of the protective cover with the space interposed between the casing and the outer edge of the protective cover is a hydrophobic region where a contact angle of a droplet is equal to or larger than a predetermined angle.

    Abstract: A vibration device includes a cylindrical vibration body portion including a cylindrical member and a piezoelectric vibrator fixed to the cylindrical member, and a light-transparent body portion that includes an outer peripheral portion connected to an end surface of the cylindrical member and a light-transparent portion positioned in front of a lens. The light-transparent body portion vibrates in a bending mode by vibration of the cylindrical vibration body portion. The bending mode includes a first bending mode in which a center-maximum-displacement portion of the light-transparent body portion and the outer peripheral portion of the light-transparent body portion connected to the end surface are displaced in the same direction and a second bending mode in which the center-maximum-displacement portion of the light-transparent body portion and the outer peripheral portion of the light-transparent body portion are displaced in opposite directions.

    Abstract: A voltage converter is provided that includes a variable inductor device that is disposed between an input line and an output line, a switching device that is disposed between the input line and the variable inductor device, a capacitor that is disposed between the output line and a ground line and a control circuit configured to switch an inductance value of the variable inductor device and to switch a control mode of the switching device according to a load current in the output line. The control circuit is configured to set the inductance value of the variable inductor device to a first value when the load current is less than a threshold value and set the inductance value of the variable inductor device to a second value that is smaller than the first value when the load current is higher than the threshold value.
