摘要： An output power control circuit is provided in a casing of a mobile radio apparatus together with an automatic power control circuit and an RF signal amplifier. The output power control circuit applied level control signals to the automatic power control circuit for maintaining the power level of the output RF signal of the RF amplifier at one of a plurality of output power levels corresponding to the level control signals. The output power control circuit has a receiver, a temperature sensing circuit and a logic circuit. The receiver receives RF signals transmitted by a master station and detects power level setting command signals included in the received RF signal. The temperature sensing circuit detects an internal temperature of the casing and provides a power reduction signal upon detecting that the internal temperature has exceeded a predetermined temperature. The logic circuit receives the power level setting command signal from said receiver, and generates a level control signal for determining an output power level corresponding to the power level setting command signal, and generates a level control signal for determining an output power level which is lower than that specified by the power level setting command signal upon receiving the power reduction signal from the temperature sensing circuit.

摘要： An overcurrent protection apparatus for a DC motor which can be used with a speed control system of a DC motor to prevent an overcurrent condition arising when the DC motor is run with a heavy load or locked by an overload from burning or overheating windings of the motor. The apparatus is constructed using at least one integrated circuit and includes a current mirror circuit for detecting an overcurrent and for cutting off the supply current of the DC motor. A timing circuit prevents overcurrents lasting only a short time from triggering the apparatus to shut down the motor. Once the apparatus is triggered to shut off the motor, the motor will remain off for an indefinite period of time until the apparatus is reset.

摘要： A region containing a high concentration of impurity and a desired region adjacent thereto are fused by irradiation with a laser beam, to diffuse the impurity in the lateral direction into the desired region and to render the desired region a low resistance.Since this method can execute only the lateral diffusion of the impurity without affecting other portions, it is very useful for forming a high breakdown voltage MIS-FET, a resistor etc.
