A cylindrical tube extending from a fluid reservoir to a location that is convenient to fill the reservoir. Some hydraulic reservoirs and fuel tanks are installed inside an aircraft structure in a location where servicing is difficult. A filler neck is installed on these reservoirs to allow them to be filled from outside the aircraft.

A damaged head on a chisel or punch caused by hammering on the tool. Mushroomed heads are dangerous, because a piece of the metal can be easily broken off and cause injury. A mushroomed head must be ground off of a tool as soon as it forms.

A dark brown, tetravalent (having four valence electrons), nonmetallic crystalline chemical element. Silicon’s symbol is Si, its atomic number is 14, and its atomic weight is 28.086. Silicon is the second most abundant chemical element in nature (oxygen is the most abundant). Because of the ease with which silicon unites with oxygen to form silicon dioxide (sand and quartz), it is never found in nature in its pure state.
Silicon is used to make semiconductor diodes, transistors, and all forms of integrated circuit devices.

A decision based on logic. This is the type of decision made by a digital computer when there are two possible conditions or alternatives.
If a computer is instructed to count ten items and then turn off the power to a motor, it will count one item and then ask for a logic decision to be made: “Have ten items been counted?” If the answer is NO, the computer will make the logic decision to count again. After the tenth item has been counted and the computer asks the question “have ten items been counted?” the answer is now YES, and the computer will make the logic decision to turn off the power to the motor.
A decision point where the computer is asked to make a logic decision is shown on a flowchart as a diamond.
