FEP

Reading: Front-End Processor and [ehuipi]
Full spelling: Front End Processor
Field:
Software > type > Japanese input > FEP

Thing of the auxiliary processor which does the pretreatment of the data and the control etc of data transfer in order is old, to lighten the burden of the main processor in the large-sized computer system, was displayed. Changing, it reaches the point where it points to the device and the generality software which, do the assistance of pretreatment and input of the data on the MS-DOS system it uses in order to input , it became fixed the kana Chinese character conversion software (“ATOK” of the just system and so on) as a general term. Presently as for the Japanese input software IM (Input Method) with there is many a thing which is called, but when the terminology, FEP in still this sense is used, it is.

FeRAM <Ferroelectric memory>

Reading: [ehuiramu]
Full spelling: Ferroelectric Random Access Memory
Alias:
FRAM
Field:
Semiconductor > memory > RAM > FeRAM

One kind of non- volatilization memory which utilizes the ferroelectric.

The substance where stores electric charge the ferroelectric, spontaneous polarization inside the substance (when electric plus and minus has occurred inside the substance) it changes direction freely by adding voltage, does not apply voltage and the dielectric which also the [te] can make that polarization direction continue (with polarization, does not pass through direct current) it is thing, the non- volatilization memory which designates this as the storage cell is FeRAM.

As for FeRAM structure and the like having been similar to DRAM, the high speed which reaches 10 times that or more flash memory reading and writing is possible. In addition, it is called on markedly flash memory, in comparison with EEPROM regarding the aspect of reliability. As for FeRAM also “FRAM” is called, but this is registered trade mark of the Ramtron corporation.

FET <Field-effect transistor>

Reading: [huetsuto]
Full spelling: Field Effect Transistor
Field:
Semiconductor > basis technology > FET

At one of structure of the transistor, the system which controls the flow of electric current with the electric field which it occurs from the gate electrode. The carrier which carries electric current one of the unipolar transistor which kind is similar and it does not use.

FET the source - between the drain the electron or the positive hole which flows (the hole) controls the flow by putting voltage on the gate terminal with three terminals “of source” “gate” “drain”.

There are several types in concrete structure, but those where it is used widely the metal (Metal) - semiconductor oxide (Oxide) - the semiconductor (Semiconductor) are designed to be three layer system, “MOSFET” is. This on the semiconductor baseplate of silicon and the like makes the insulator film with the oxide of the semiconductor, is designed to be the structure which on that piles up the gate electrode with the metal.

FFB <Fourth feedback>

Full spelling: Force Feed-Back
Field:
Multimedia > game > game machine for home > FFB

At functional one which has been attached to input device such as controller of the game machine, reacting to input, the function which adds the vibration and power to the hand. Even feeling simulation it is said.

For example, when the automobile it drives, the vibrating and resistant impression joins in the hand which grasps the steering wheel according to the body and road surface circumstance, but in order to reproduce this with the race/lace game and the like, those where it is built in to the steering wheel type controller are fourth feedback mechanism. From it is possible in addition to eyesight and hearing, by approaching also the antenna, to make the game which has the appearance impression with real.

The input device which imitates the gun (the cancer/gun controller) on the picture of the product and the personal computer which install the function which reproduces the impact when firing there is also a mouse and the like which vibrates according to operation.
