Notching relay à fires after receiving a number of impulses
Wien bridge à measuring capacitance
Kelvin double bridge à for measuring low resistances
+β decay à positron decay; proton to neutron
-β decay à with gamma radiation; for lowering binding energy
Crystal defect à line defect; most common; A.K.A. edge dislocation
Flip-chip and beam-lead packaging à eliminates need for bonding wires
Flip-chip à conducting paths evaporated on chip before die is inserted
Electronic data message
Commutator polishing paste
TO packaging à IC packaging similar to transistor; early packaging
DIP à for easier insertion to PCB
Brushes in repulsion motor à connected by jumper wire
Not part of categories of losses in rotating machines à hysteresis losses

FORTRAN à 1950’s
Chromium à body-centered cubic crystalline
1 atom per cell in cubic crystalline structure
Atom volume/cell volume à packing factor
0.74 à packing factor of face-centered cubic structure
NMOS à fastest MOS transistor in IC
instrumentation amplifier à for getting small signals from large common-mode noise
Electrodynamometer à with 2 coils, fixed and moving; meter movement
Magnetomotance à work involved in moving charge around a loop in a current-carrying conductor
Fixed-stop à open-loop movement; open loop – parameters are dictated by the system’s physical parameters
Principle of magnetic amplification à permeability of core decreases with increase in current
Mesons à 0.1 amu
