Further, a power transistor 5 which is installed on a heat spreader 7 contiguously to the printing substrate 8 is fixed through an insulating plate 9. Further, one edge sides of a plurality of external electrodes 6 are connected with the printing substrate 8 and the heat spreader 7. The whole periphery of the heat radiation plate 1, electronic parts, etc., are molded by a package 2 through the transfer molding so that the other edge side of each external electrode 6 projects outside the package 2. Accordingly, even if a gap is generated between the heat radiation plate 1 and the package 2 because of the difference of the thermal expansion rate, intrusion of the contaminated gas into the gap is prevented. Accordingly, the oxidation of a soldered connected part can be prevented.

Filed: 1986-10-31
Abstract: PURPOSE:To detect a flaw in the wall of a tank speedily and securely by measuring a projection signal contained in an infrared ray emitted by the wall of the heated tank. CONSTITUTION:When the side wall 11 made of a steel plate is heated by an induction heater 21, the infrared ray is emitted from the side wall 11. Here, the side wall 11 is scanned through a polygon mirror 41 and the infrared ray is entered into an infrared sensor 40 through a condenser lens 42. The side wall 11 is heated almost uniformly by the heater 21, but the side wall 11 has a temperature distribution under the influence of the heat capacity of the side wall 11, winds, etc., and the output signal of the sensor 40 waves gently as shown in a graph (b). Then if there are flaws 10a-10c on the surface of the side wall 11 or in the side wall, a current generated by an induction heating means 20 becomes higher in density at the flaw parts than at other parts and the heat generation by induction heating increases as compared with other parts. For the purpose, infrared rays from the flaw parts 10a-10c are detected by the sensor 40, and then fine temperature rises are caused at corresponding parts and fine projection signals 60a-60c are generated at the timing of them. The flaws of the wall of the tank are detected with the projection signals.
