Electro-Motion Devices - Essay Example This novel electro-motion device has been explained in the paper below. The common electro-motion devices comprise of the normal rotary machines running on both AC and DC power supply. In addition to these, electro-motion devices also produce linear motion, controlled rotary and linear motions. On most of the occasions, the linear motion in an electro motion device is produced using rotary equipment. For long traveling devices, motors are used with appropriate capacity. Stepper motors and servo controlled motors are normally used for small and incremental movements needed out of electro motion devices. These motors are normally rotating devices. They are not directly producing linear movement. However, there are devices which produce controlled linear movement. Uncontrolled linear devices are used in high speed trains typically, the bullet trains. In some special applications, rotating devices need to be controlled to an accurate angle. This kind of controlled movement becomes a tough implementation because of the motor's speed and the reduction that mi ght be required. These are normally used for controlling the movement of telescopes and antennas in radar systems. The electro motion device for rotation control is a common requirement. ... The ball valve is normally operated using either a mechanical lever or a rotating member or it could be a pneumatically operated valve. The ball valves are used to control the flow rate and could be placed in any of the angles to control the flow. In order to realize this, an electro motion device is used more comfortably rather than use one of the indicated methods. The design consists of a large gear wheel connected to a standard AC motor. This motor to gear ratio is predetermined in such a way that the motor has to rotate about 100 times to realize one complete rotation of the gear wheel. One rotation of the gear wheel will, in turn, open the valve fully. If the gear wheel is to be rotated only through half of the rotation, then the valve will be open ninety degrees. The design of the gear wheel has to take into consideration the size of the motor drive gear. The ratio between them has to be one hundred ensuring that the motor rotates one hundred times to open the valve fully. By controlling the motor and the number of times it could rotate, the opening of the valve could be controlled. The percentage opening obtained is exactly proportion to the number of rotations that the motor has performed. If it has rotated twenty times, then the valve is open for twenty percent. The same logic is maintained for one hundred percent opening too. The working of the device varies with the options that are required. In the process industries where such devices are put to use, the electro motion ball valve can be used in any of the following applications: 1. Steam handling 2. Non Corrosive liquid handling 3. Corrosive liquid handling 4. Gas handling 5. Sludge or semi solid handling Depending on the viscosity of the fluid that is

Micro Economics - Competition Essay Example | Topics and Well Written Essays - 1750 words

Micro Economics - Competition - Essay Example However, not all situations can the management plan on how to counter the competitors. In most cases, these situations arise due to unavoidable circumstances facing an organization. Whenever such situations arise, an organization’s management has to take drastic measures of solving the problem. How firms solve the problem of competition in the two scenarios forms the main discussion of this paper. Short-Run Decisions and Long Run Adjustments of Firms Facing Competition Introduction Competition occurs in perfect market structures where firms operate in a perfectly competitive market structure. In perfect competition, many small firms involved in the production of identical products with perfect access to resources and knowledge characterize the market structure. Firms operating in a perfectly competitive market structure face a horizontal and perfectly elastic and demand curve, a situation where marginal revenues are equal to average revenue. Characteristics of perfectly compet itive markets include perfect knowledge, freedom of entry and exit of firms, production of homogenous and identical units of output and many firms in operation. The structuring of a perfect market does not give an opportunity to a single firm to either influence the market price or market conditions, there are no governmental regulations and the assumption there is no existence of externalities. Body Faced with the problem of competition, organizations have to device ways and means of preserving their relevance in the market. Various factors affect the relevance of organizations in the industry they operate. Jain and Khanna (198) assert that quality and the popularity of an organization’s products among the customers determine the market share of that company in the market it operates. Competition indirectly acts as a quality controller. As companies increase their fight for a bigger cake in the entire market, they apply a number of measures. Firstly, companies increase their focus on the quality of products provided to the market while at the same time strives to offer the best prices in the market. Pricing is not an influential factor as high-end markets have indicated. Quality is the biggest factor influencing the market dynamics and purchasing behaviours of customers. Compromising quality of products adversely effects on the customers base of a company. Companies known to high quality products and services are associated with large market shares and subsequently report high revenues and profits. While laying down strategies for winning their competition, organizations apply a number of means and ways. Although every organization uses unique strategies in the market geared towards increasing its revenue sales, there are similar steps that organizations use to achieve these results. Either, an organization can opt for long term or short-term competition mitigation factors. While long-term plans needs a solid strategic plan and implementation schedule, short term decisions could be spontaneous and reactive. Reaction is a situation where a company facing high competition from other firms operating in the same industry takes drastic measures of countering that competition. Mainly, the management as measures of last result takes such measures. However, the management of an organization should be adequately prepared to counter any in eventualities whenever they occur in their operations. Whenever
