An unassembled IKEA flat-pack stool. Ready-to-assemble furniture (RTA), also known as knock-down furniture (KD), flat-pack furniture, or kit furniture, is a form of furniture that requires customer assembly. The separate components are packed for sale in cartons which also contain assembly instructions and sometimes hardware.
In marketing, lead generation (/ ˈ l iː d /) is the process of creating consumer interest or inquiry into the products or services of a business. A lead is the contact information and, in some cases, demographic information of a customer who is interested in a specific product or service.
Motor control centers are usually used for low voltage three-phase alternating current motors from 208 V to 600 V. Medium-voltage motor control centers are made for large motors running at 2300 V to around 15000 V, using vacuum contactors for switching and with separate compartments for power switching and control.
The number of leads is always even. For 0.3 inch spacing, typical lead counts are 8, 14, 16, and 20; less common are 4, 6, 18, 24, and 28 lead counts. To have an even number of leads some DIPs have unused not connected (NC) [nb 1] leads to the internal chip, or are duplicated, e.g. two ground pins. For 0.6 inch spacing, typical lead counts are ...
The PLCC uses a "J"-lead with pin spacings of 0.05" (1.27 mm). The metal strip forming the lead is wrapped around and under the edge of the package, resembling the letter J in cross-section. Lead counts range from 20 to 84. [5] PLCC packages can be square or rectangular. Body widths range from 0.35" to 1.15".
Washer design improved during the 1930s. The mechanism was now enclosed within a cabinet, and more attention was paid to electrical and mechanical safety. Spin dryers were introduced to replace the dangerous power mangle/wringers of the day. By 1940, 60% of the 25,000,000 wired homes in the United States had an electric washing machine.
As an example, a 250 kVA motor–generator operating at 300 ampere of full load current will require 1550 ampere of in-rush current during a re-closure after 5 seconds. This example used a fixed mounted flywheel sized to result in a 1 ⁄ 2 Hz per second slew rate. The motor–generator was a vertical type two-bearing machine with oil-bath ...
