ABSTRACT Mechanical Engineering Department of the named Institute has many non – operational malhiues. Sequel to the fact, maintenance was poorly excuted which resulted to the breakdown deep freezer.Quality and effectiveness of machine maintenance were well observed. Also, a minimized maintenance and a highly successful repair was adopted.In other words during the repair and rehabilitation of the facility Deep Freezer, appropriate tools, cost and quality of materials were w...
INTRODUCTIONPower amplifier is an electronic device, which is used to increase sound energy. In other words, the final stage which must driven a given load e.g mechanical indicator, a loudspeaker cathode roy tade, magnetic deflection coil, a transmitting accrual of a communication network. Power amplifier is also used in regulation power supplies, chopper amplifier, motor controller etc. In general the load will by its nature, demand a certain power from the amplifier and th...
ABSTRACTThis work was centered on the Design and implementation of a simple scientific calculator for education organization. The study traced calculator system as a tool to completely change mathematical knowledge and sophisticated problems solving strategies had advanced the field of simulated engine in mathematic. This project work also focused principally on numbers and arithmetic operation. This researcher investigated the manual system in detail with a view to finding out th...
ABSTRACT In this project (3) alternative design solutions were considered for the locally made electric run. The authors utilize the available local raw demerits of each alternative with respect to the considered group were discussed and the solutions of the alternative that best satisfied the limitations was selected for production. Material selection, design and cost of analysis, production processes and operation maintenance and problems encountered during the design were also included.&nb...
ABSTRACT In all types of air –conditioning work a through knowledge of basic principal is varying important. The report of the project “re pair and rehabilitation of a faulty Air–conditioner” serves as guide to project implementation. It explains and illustrates the import principle of operation and various maintenance procedures in an understanding manner.The report is divided into four chapters, which covers the practical application of air-conditioner in the field of domestic, busi...
ABSTRACTThis write up outlines the design and fabrication of wood lathe machine. This type of lathe is capable of creating different wood designs using the cheapest available material and method.To achieve functional and efficient wood lathe of this kind, we analyzed as well as synthesized the different possible design solutions and concepts.The principle of turner is puts into consideration the case of its production, main finance and services, values durability , reliability and...
LETTER PRESS PRINTING1.1 THE BASIC PRINCIPLE:Letterpress is a highly versatile printing process. It is adaptable to both short and long printing runs, from a few hundreds to several millions of printed impressions. In letterpress printing the image area of the printing surface stands in relief, raised above the surrounding non-image areas. Ink is applied to the image areas with a roller and is transferred to paper under pressure. Letterpress printing process is derived from pre-industrial art...
ABSTRACTDescription of a system and peripherals or devices in a computer system in which the operating of such devices is under control of the central processing unit is termed on-line. Because of the efficiency and fast services, this project is equally aimed at creating a computer based lottery which allows entire to be sold over the phone, ATM, POS Machine, E-mail or via kiosks in which participants are invited to choose at least one unique number from a defined range of numbers. &nb...
ABSTRACTThe ill treatment that take place in our motor vehicle Drivers licensing office today, one have to wait endlessly in order to get his driver’s licensing or renew his driver license and so on. This is a problem that is experienced daily, which robs the government a huge sum of money through fraudulent means. Being a system run manually, it is prone to many man-made errors both intentionally and unintentionally, which could be unnecessary delays in attending to customers due to ...
ABSTRACTVoting is a very important process in the Nigerian political system. It is one of the means and most effective method of ensuring a legitimate government through popular participation. To enthrone sound democracy and stability in the political system of the Enugu state a system of rig-free voting has to be put in place.The system would among others discourage double voting, forgery or hoarding of electoral materials massive transfer of ballot papers destruction of ballot b...
ABSTRACT The magical impact of computer has made enormous contribution to all aspect of the society people can now do things easily unlike in the past. Computers have lesson human activities (effort) in their day to day life, by reducing both human labour and time in solving their problem which are both numerous / unlimited. The introduction of the magical machine has led to the further growth of Agricultural products. The technological know how and scientific research reveals that a lot of w...
INTRODUCTIONEach machine consists in principle of three basic parts: a motor or another prime mover (that sets the machine in motion), an actuating mechanism (which is directly doing the needed work:digs a ditch, weaves cloth, peels potatoes, propels a ship, and so on), and a transmission that connects the first two parts. Sometimes, the transmission may be lacking, for example, in a fan the impeller is mounted directly on the shaft of the electric motor. But in most cases, the transmis...

INTRODUCTION REFRIGERATION Refrigeration is a branch of science that deals with the process of removing heat from a substance or space in order to make it cooler. Refrigerator is defined as a device that is used in cooling the internal temperature below the room temperature (that is between 250C to 300C). Generally, however, for a space or substance to be cooler, it must loss that heat to another. Also, for a space or substance to get hotter, it must absorb heat from another, which...
ABSTRACTIn the mechanical engineering department of institute of management and technology there are many machines but it is not all that is functioning well.This may airless as a result of lack of maintenance which is a prove in the breakdown of the air conditioner.The quality and effectiveness of materials were mated very well as referred to machine maintenance. The cost of maintenance was minimized jet reaching a highly victorious rehabilitation.In the course of rehabilitation and r...
