摘要： A semiconductor device includes: first to fourth vertical type semiconductor elements having first and second electrodes; a metallic lead; a resin mold; a circuit board; an electric circuit on the circuit board; and an electronic chip on the circuit board. The electronic chip drives and controls each semiconductor element through the electric circuit. The first to fourth semiconductor elements are arranged to be a stack construction in the resin mold. The first to fourth semiconductor elements provide a H-bridge circuit. Each of the first and second electrodes in each semiconductor element is directly connected to the metallic lead so that heat generated in the semiconductor element is radiated through the metallic lead.

摘要： An electronic device includes: a first substrate and a second substrate; a lead frame disposed between the first and the second substrates for electrically connecting therebetween; and a first groove and a second groove disposed on the first and the second substrates, respectively. The first and the second grooves correspond to a connection portion between the first and the second substrates and the lead frame. The lead frame is connected to the first and the second substrates in such a manner that one end of the lead frame is engaged in both of the first and the second grooves through a conductive bonding material.

摘要： A magnetic circuit suitable for a self-held type rotary solenoid while maintaining properties, reducing cost, e.g., a material cost, and making the rotary solenoid smaller in size is provided. The rotary solenoid includes a swing yoke to which two magnets are fixed and a fixed yoke including projection portions at opposite sides thereof. An electromagnetic coil including a major magnetic pole is arranged at a center of the fixed yoke. The rotary solenoid is arranged to define a magnetic circuit extending through one of the magnets, the major magnetic pole, the fixed yoke, the projection portion, and the other magnet at a shortest distance. Therefore, even if a magnet made of a material having a low grade is used, it is possible to maintain sufficient magnetic properties.
