A.Cordless telephones.

B.Miracles of modern life.

C.A combination of a telephone and an FM radio transmitter.

1.Cordless telephones are one of those minor miracles of modern life – with a cordless telephone, you can talk on the phone while moving freely about your house or in your yard. Long before cell phones became so cheap that anyone could afford one,

cordless phones gave everyone the freedom to walk and talk within the privacy of their own homes. A cordless telephone is basically a combination telephone and radio transmitter/receiver. A cordless phone has two major parts: base and handset.

2. The base unit of the cordless phone is plugged into the telephone jack on your wall. If you open up the base and expose the circuit board, you'll see several components that carry out the functions of the base:

•phone line interface – receives and sends telephone signals through the phone line;

•radio сomponents – amplifies signals to and from phone-line interface, user controls and speaker phones (if present); broadcasts and receives radio signals to and from the handset;

•power сomponents – supplies low voltage power to the circuits and recharges the battery of the handset.

3. You can carry the handset with you throughout the house or outside within the range of the base transmitter. The handset has all of the equipment of a standard telephone (speaker, microphone, dialing keypad), plus the equipment of an FM radio transmitter/receiver. When you open up the handset, you can see these components:

•speaker receives the electrical signals from the audio amplifier in the radio components and converts them into sound;

•microphone changes the sound waves from your voice into electrical signals that are sent to the audio amplifier of the radio components;

•keypad allows you to dial a number. It transfers the pressure from your fingertip on the appropriate key into an electrical signal that it sends to the radio components.

4.When the radio components of the handset receive the ringer signal from the base, they send electrical signals to the buzzer. The buzzer changes those electrical signals into sound much like the speaker does. You hear the buzzer sound and know that someone is calling you.

5.The radio components of the handset are like those of the base – they convert electrical signals from the microphone into FM radio signals and broadcast them at the same frequency as the receiving crystal of the base unit.

6.The handset's battery supplies the power for all of the electrical components in the handset. All cordless phone handsets have a rechargeable battery.

A.Constant current power supplies.

B.Power supplies in welding processes.

C.Arc welding processes.

1.To supply the electrical energy necessary

for arc welding processes, a number of different power supplies can be used. The most common welding power supplies are constant current power supplies and constant voltage power supplies. In arc welding, the length of the arc is directly related to the voltage, and the amount of heat input is related to the current. Constant current power supplies are most often used for manual welding processes such as gas tungsten arc welding and shielded metal arc welding, because

they maintain a relatively constant current even as the voltage varies. This is important because in manual welding, it can be difficult to hold the electrode perfectly steady, and as a result, the arc length and thus voltage tend to fluctuate.

2.Constant voltage power supplies hold the voltage constant and vary the current, and as a result, are most often used for automated welding processes such as gas metal arc welding, flux cored arc welding, and submerged arc welding. In these processes, arc length is kept constant, since any fluctuation in the distance between the wire and the base material is quickly rectified by a large change in current. For example, if the wire and the base material get too close, the current will rapidly increase, which in turn causes the heat to increase and the tip of the wire to melt, returning it to its original separation distance.

3.The type of current used also plays an important role in arc welding. Consumable electrode processes such as shielded metal arc welding and gas metal arc welding generally use direct current, but the electrode can be charged either positively or negatively. In welding, the positively charged anode will have a greater heat concentration, and as a result, changing the polarity of the electrode has an impact on weld properties. If the electrode is positively charged, the base metal will be hotter, increasing weld penetration and welding speed. Alternatively, a negatively charged electrode results in more shallow welds.

4. Nonconsumable electrode processes, such as gas tungsten arc welding, can use either type of direct current, as well as alternating current. However, with direct current, because the electrode only creates the arc and does not provide filler material, a positively charged electrode causes shallow welds, while a negatively charged electrode makes deeper welds.
