Abstract: PURPOSE:To obtain a hybrid IC durable for large electric power by simultaneously forming an Ni plated layer secured with a lead wire and a low resistor. CONSTITUTION:An Al2O3 layer 2 is formed on one surface of aluminum plate 1, and a copper foil roughed on the back surface is bonded thereto with insulating resin 3. When the copper foil is etched to form an electroconductive path 4, rough surface 5 is formed on the surface of the resin 3. A resist mask 7 is coated thereon, an activator is coated thereon, and an Ni-plated layer 7 an Ni-low resistor 8 are formed thereon by an electroless plating process. The plating conditions are suitably selected to control an Ni-film thickness. Then, with the resistor 8 as one electrode the path 4 is as another electrode to execute an electrolytic plating thereon to reduce the Ni- plated layer 7. The mask is removed, is brushed to remove burrs, a semiconductor element 11 is secured onto the path 4, and is connected to a wire 11. In this configuration no contact resistance occurs at the superimposition of the path 4 and the resistor 8 to improve the heat dissipating efficiency and a hybrid IC durable against large current is thereby obtained.

Abstract: PURPOSE: To prevent the conducting current of the switch element from exceeding the limit value of the conducting current which is decided by the smaller one of the excitation property of the transformer and the interrupting property of the switch element, by giving the control to the conducting period of the switch element.  
     CONSTITUTION: The switch element 4 is turned on by the ion signal produced by the oscillator 11, and at the same time the element current, i.e. the exciting current of the transformer 3 is observed by the element current detector 7. This measured value is then compared through the comparator 9 with the value 8 set at the limit value of the conducting current which is decided by the smaller one of the excitation property of the transformer 3 and the off property of the element 4. And when the measured value reaches the set value 8, the off signal is generated by the off signal generator 10 to turn off the element 4. Thus the conducting period is of the element 4 is controlled to secure the protection against the faulty working of the circuit such as the breakdown of the element 4 and the saturation of the transformer 3. As a result, a compact and light-weight switching power source, which is suited for the power source of the electronic range or the like, can be obtained.
