Translation guide
The English word 'acceptor' is a technical term used mainly in science and engineering. This guide covers how to express the concept in Japanese, focusing on common equivalents in electronics, chemistry, and biology.
An impurity atom that accepts an electron, creating a hole in a semiconductor.
The standard katakana loanword used in semiconductor physics. Widely understood in technical contexts.
シリコンにアクセプタをドープする。
Dope silicon with an acceptor.
An alternative katakana spelling, less common but still used in some texts.
アクセプター準位は価電子帯の近くにある。
The acceptor level is near the valence band.
A literal translation meaning 'acceptor impurity'. Rarely used; the loanword is preferred.
受容体不純物としてボロンが使われる。
Boron is used as an acceptor impurity.
A chemical species that accepts an electron during a reaction.
The standard term for 'electron acceptor' in chemistry. Used in contexts like redox reactions and photosynthesis.
酸素は最終電子受容体として働く。
Oxygen acts as the final electron acceptor.
The same loanword is used in chemistry, especially in contexts like donor-acceptor pairs.
A broader term meaning 'acceptor' or 'receptor'. Can be ambiguous without context; usually specified as 電子受容体.
A molecule or cell that receives a signal or substance. Note: In biology, 'acceptor' often overlaps with 'receptor', but 'acceptor' may imply a more passive binding role.
Used for both 'receptor' and 'acceptor' in biological contexts. For clarity, specify the type (e.g., ホルモン受容体).
インスリン受容体は細胞膜にある。
Insulin receptors are on the cell membrane.
Sometimes used in biochemistry for specific acceptor molecules, e.g., in group transfer reactions.
A device that accepts bills or payments, such as in vending machines.
Literally 'bill accepting machine'. Common in technical descriptions of vending machines or payment terminals.
この自販機の紙幣受入機が故障した。
The bill acceptor of this vending machine is broken.
Loanword from 'bill acceptor'. Used in industry jargon.
新しいビルアクセプタに交換する。
Replace with a new bill acceptor.
In electronics and chemistry, アクセプタ (or アクセプター) is the standard loanword and is unambiguous. 受容体 is a broader term that can mean 'acceptor' or 'receptor' and is more common in biology. Use 電子受容体 for 'electron acceptor' in chemistry to avoid confusion.
半導体ではアクセプタが正孔を作る。
In semiconductors, acceptors create holes.
細胞の受容体に結合する。
It binds to the cell's receptor.
Direct translations like 受取人 (recipient) or 引受人 (guarantor) are incorrect for the technical sense of 'acceptor'. Stick to the domain-specific terms above.
この分子は良いアクセプタだ。
This molecule is a good acceptor.
この反応では受容体が必要だ。
An acceptor is needed for this reaction.
It acts as a methyl group acceptor.
