摘要： PROBLEM TO BE SOLVED: To solve the problems that, since nowadays, plastic materials recovered from various used home electric apparatuses contain various kinds of materials, even if they are classified by the material, suppressing of a cost up of the material owing to removing impurities adhered to the waste and controlling for a color tone are difficult, and that almost of the plastic waste is not reused but discarded or spent as a fuel. SOLUTION: Hence a treatment capable of recycling is done while suppressing increasing of the cost of recycled plastics, utilization ratio of the recycled plastics is made higher by using the recycled material as an outside design part used much amount of plastics. For example, only a used fan is fractionally collected, producing recycled plastics and they are used again as a fan. For raising a utilization ratio, the used amount or utilized ratio of the recycled plastics in the total amount of the product is represented on the main product body or its catalog.

摘要： PROBLEM TO BE SOLVED: To solve the problem that a final-stage transistor generates an excessive output for thermal breakdown if load fluctuation occurs in an operation state at an overvoltage power supply.
SOLUTION: An overvoltage output protection circuit 71 for a power amplifier comprises monitor circuits (Trf1-Trf4) which allow a current to flow when an overvoltage output is monitored at an output transistor Tr3 at a final stage of a power amplifier 51, and current mirror circuits (Trm1 and Trm2) that supply a current proportional to the current from the monitor circuit. The output of the output transistor Tr3 at the final stage is suppressed by lowering the base bias of a first-stage transistor Tr1 using the current supplied from the current mirror circuit.

摘要： PROBLEM TO BE SOLVED: To prevent a transistor for power amplification from breaking owing to output load vibration by electrically connecting a collector to a base electrode of the transistor at least in the final stage of the power amplifiers which are connected in multiple stages and supplying a feedback current to the base electrode against a voltage higher than a prescribed one applied to the collector electrode. SOLUTION: The ON voltage of a TR 103 is about 1.3 (V), the value of a resistance 101 is denoted as Rfb1, and the value of a resistance 102 is represented as Rfb2. Then a protecting circuit 100 supplies a feedback current If1 from a point 107 to a point 105 by turning ON the TR 103 when the voltage Vf1 between terminals 108 and 109 exceeds (Rfb1+Rfb2)/Rfb2×1.3 (V). An ON voltage at which the protecting circuit 100 begins to function as a feedback circuit is set to a value which is larger than that of an ordinary collector bias voltage Vc3 supplied to a terminal 514 and less than that of the breakdown voltage of a TR 505.
