Abstract: The utility model provides a cupboard lamp, comprising a battery compartment; wherein the battery compartment comprises a compartment housing component and a compartment cover component; the compartment housing component comprises a first battery cavity and a second battery cavity; the compartment housing component also comprises a third battery cavity; and the third battery cavity is positioned between the first battery cavity and the second battery cavity, and is higher than the first battery cavity and the second battery cavity. The third battery cavity is disposed at a relatively higher position between the first battery cavity and the second battery cavity, so the battery compartment is more compactly structured and has a better power supply capability. The cupboard lamp has a long service life, a smaller size and a more beautiful appearance.

Abstract: The starter has a system of pushing the pinion gear in the direction of the anti-motor side by using the attracting power of the electromagnetic switch via the shift lever. The switch coil of the electromagnetic switch is constituted of one coil that is electrically separated from the motor circuit. The mass of pinion gear is set to 100 g or less, the switch extrusion power stored in the drive spring is set to 70N (Newton) or less, and the operation current of the electromagnetic switch is set to 12 amperes or less. With this starter, since the switch coil and the motor circuit can be electrically separated, the terminal for connection for connecting the conventional attracting coil and conventional “M terminal bolt” can be abolished. Further, by setting the operation current of the electromagnetic switch 10 to 12 amperes or less, it is possible to control the operation current directly by the ECU.

Abstract: An on-chip inductor includes a main inductor portion configured to provide a main magnetic field of an on-chip inductor. An interconnect inductor portion is electrically coupled to the main inductor portion and is configured to provide an interconnect magnetic field that constructively combines with the main magnetic field.

Abstract: An ignition coil contains an elongated substantially circular coil core which includes a primary coil and a secondary coil each disposed radially outwardly of the core with the core composed of a plurality of generally rectangular elements at least some of which have a different width than others and the elements being in surface-to-surface contact with each other. The lateral walls of the elements may have a shape which is not perpendicular to the longitudinal extent of the elements. The core may be welded at its ends. A core contained within this ignition coil, which may be an automotive ignition coil, is disclosed.
