Advent of the TYCO brand. Launching in 1957, Mantua pioneered HO-scale model railroad “ready-to-run” die-cast locomotives. These products, also available as assembly kits, were sold under the "TYCO" name (for "Tyler Company"). [3] Many TYCO and Mantua die-cast products, such as steam engines, are collector's items today.
Used to separate Uranium 235 isotope for the Manhattan project, after the end of World War II used for separation of medical and other isotopes. 95-inch cyclotron. Harvard Cyclotron Laboratory. 1949–2002. Circular. Proton. 160 MeV. Used for nuclear physics 1949 – ~ 1961, development of clinical proton therapy until 2002.
A diagram of a Rhodotron. The electron beam is in red. E is the electron gun, L is an electron lens, C is the radiofrequency cavity, and M is a bending magnet. A Rhodotron is an industrial electron accelerator first proposed in 1987 by J. Pottier of the French Atomic Energy Agency (CEA), [34] manufactured by Belgian company Ion Beam ...
v. t. e. Paramagnetism, ferromagnetism, and spin waves. Ferromagnetismis a property of certain materials (such as iron) that results in a significant, observable magnetic permeability, and in many cases, a significant magnetic coercivity, allowing the material to form a permanent magnet. Ferromagnetic materials are noticeably attracted to a ...
A neodymium magnet (also known as NdFeB, NIB or Neo magnet) is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd 2 Fe 14 B tetragonal crystalline structure. [1] They are the most widely used type of rare-earth magnet. [2] Developed independently in 1984 by General Motors and in 1970s by Sumitomo Special Metals ...
Semiconductor device. A semiconductor device is an electronic component that relies on the electronic properties of a semiconductor material (primarily silicon, germanium, and gallium arsenide, as well as organic semiconductors) for its function. Its conductivity lies between conductors and insulators. Semiconductor devices have replaced vacuum ...
A rare-earth magnet is a strong permanent magnet made from alloys of rare-earth elements. Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets. The magnetic field typically produced by rare-earth ...
A machinist at a lathe. Tool and die makers are highly skilled crafters working in the manufacturing industries. Tool and die makers work primarily in toolroom environments—sometimes literally in one room but more often in an environment with flexible, semipermeable boundaries from production work. They are skilled artisans (craftspeople) who typically learn their trade throu
