摘要： Provided is a method for producing a heat sink that can easily and effectively form a heat radiating film on the surface of a substrate without requiring enormous heat energy for increasing the temperature of the substrate. The method is a method for producing a heat sink having a substrate and a heat radiating film formed on the surface of the substrate, including a first step of casting a substrate by injecting molten metal into a cavity of molding dies; and a second step of applying a heat radiating coating to the substrate through spraying or dropping in the period from when the molding dies are opened after the casting until when the temperature of the substrate that has been cast becomes lower than the deposition temperature that is a temperature necessary to deposit the heat radiating coating on the substrate.

摘要： An overcurrent preventive diode comprises a diode chip sandwiched between respective bonding ends of first and second leads. The bonding end of the first lead is directly bonded to the diode chip into electrical conduction while being also kept in heat conduction with the chip. The bonding end of the second lead is held in heat conduction with the diode chip via a thin electrical insulating layer. The bonding end of the second lead and the insulating layer are shaped to expose an electrical connecting portion of the chip, thereby enabling the second lead bonding end to be electrically connected to the chip through a fusing wire which is designed to be melt-cut upon passage of a predetermined overcurrent.

摘要： An improved method for manufacturing a capacitor packaged by synthetic resin after welding an anode bar of a capacitor element with a lead terminal of a lead frame and electrically connecting a cathode of the capacitor element with another lead terminal of the lead frame, wherein the capacitor is assembled after measuring an inclination of the capacitor element in the horizontal/vertical direction after welding the anode bar of the capacitor element with the lead terminal and correcting the inclination of the capacitor element by pressing a portion of the lead terminal to which the anode bar is welded corresponding to the direction of the inclination when the inclination exceeds a predetermined value. As a result, no stress is applied to the capacitor element itself, so that no element is rendered defective or no element characteristic is damaged. In the same time, no capacitor element part will protrude out of the package or no thin package portion is created due to the inclination of the capacitor element, so that the reliability is kept.
