Abstract: A module comprises a metallic terminal pins for connection and a circuit board with electronic components mounted thereon, a circuit board connecting side of the connector. The electronic components and the circuit board with the electronic components mounted thereon are encapsulated with the same resin. A metallic base is united to the module to obtain an electric conduction between the metallic base and the circuit board.

Abstract: There is provided a high-pressure fuel pump drive circuit for manipulating the electric current to be passed to a solenoid coil for controlling a high-pressure pump.

Abstract: In resin-molded engine control unit, a coil, an electrolytic capacitor, a microprocessor, electronic parts and a connector terminal are mounted on a board. Inside a cover fixed on the board, a resin-free region is formed. The coil, the electrolytic capacitor and the microprocessor, which should not be sealed with resin, are mounted in the resin-free region, while the board and the electronic parts which are not capped by the cover are sealed with a resin.

Abstract: An electronic circuit device comprises: a printed circuit board mounted with electronic components; a resin-molded portion formed of resin so disposed that the electronic components are covered therewith; a convex connector that has metal terminals for connection and is exposed from the resin-molded portion; and a sealing member wrapped around the resin-molded portion.
