Introduction A microprocessor is multipurpose, programmable, clock driven, resister based electronic device that reads binary instruction from the storage device called Memory, binary data as input and process data according to those instructions and generates the result as an output. A central processing unit (CPU) built on a single chip is called a microprocessor . The microprocessor contains electronic circuits with a large number of electronic components (such as transistors, resistors etc...) integrated into a single component called chip . Evolution of Microprocessor Growth of Microprocessor has been several stages starting from 4-bit to present 64-bit processor and multi-core designs. A computer-on-a-chip is a variation of a microprocessor or which combines the microprocessor core (CPU), some memory and input/output (I/O) lines, all on a single chip. ·        4- bit design ·     ...

Introduction Turbojet engine takes its oxygen supply from the surrounding atmosphere. The turbojet engine consist of a diffuser, compressor, combustion chamber, turbine and a expansion nozzle. The air is compressed in to the chamber, heated and expanded by the fuel combustion and then allowed to expand out through the turbine in to nozzle were it is accelerated to high speed to provide propulsion (moving forward) Working Principle : - Atmospheric air enters into the diffuser with the same velocity as that of the propulsive unit. The function of the diffuser is to convert the kinetic energy of entering air in to pressure energy of it. High pressure air now enters into the compressor were its pressure is further increased and its temperature also increases correspondingly. The high pressure and high temperature compressed air now inters in to a combustion chamber in which a liquid fuel is injected through a ring of injectors by means of a pump. In the c...

Water jet cutting  works by forcing a large volume of water through a small orifice in the nozzle. The constant volume of water traveling through a reduced area causes the particles to accelerate.

ROBOTICS Introduction Robot is an automatically controlled material handling unit that is widely used in the manufacturing industry robots are generally used for high volume production. The term robot was derived from Czech language in 1920 which means forced labour. the official definition for the robot was given by robot institute of America Definition An industrial robot is a reprogrammable, multifunctional manipulator designed to move material, parts, tool (or) special devices through a variable programmed motions for the performance of variety of tasks. A manipulator is mechanical element that consist of series of joints and links. HISTORY OF ROBOTS Science fiction has contributed lot in the development of robots. Mid 1700's - human sized mechanized dolls were developed. Mid 1800's - mechanical dolls were able to play music. 1952         - First NC machine was developed. 1953  ...

      A  proximity sensor  is a  sensor  able to detect the presence of nearby objects without any physical contact.                           Principles of Operation for  Inductive Proximity Sensors Inductive proximity sensors are designed to operate by generating an electromagnetic field and detecting the eddy current losses generated                                                  when ferrous and nonferrous metal target objects enter the field. The sensor consists of a coil on a ferrite core, an oscillator, a trigger-signal                                              level detector and an output circuit. As a metal object...

SHAPE MEMORY ALLOY INTRODUCTION SMA is one of the smart materials a smart material is defined as one which has multiple responses to one stimulus in a coordinated manner. External stimulus can be pressure, load, electrical field or magnetic field. Smartness of the material can be attributed to the self-adaptability, self sensing, self memory and multiple-functionality. These smart characteristics provide numerous application in defense, manufacturing process and bio medical application. DEFINATION A shape memory alloy is an alloy that "remembers" its original shape and that when deformed return to its pre-deformed shape when heated, this material is light weight. Let us we discuss about the application of SMA- I explain you with one example , Everybody knows the catheter- It is a tube and guide wire which are used for the medical treatment in blood vessel are called catheter. Now days we are using active catheters using shape memory alloy. Then you...
