The ends of information sections of the tapes used for recording sound signals bear markings which adjust a control during playback. This control stops the tape until it is started up again. The magnetic tape has at least two soundtracks, one of which receives the sound signals. An ...
Magnetic tape recording: Chromium (VI) oxide (CrO3) is used to manufacture magnetic tape, where its higher coercivity than iron-oxide tapes gives better performance. Chromium 7440-47-3 You may like Hydroxyapatite: A Key Material in Chemistry and Biomedical Applications Jan 7, 2025 Scandium: Imp...

aOne of the major weaknesses of videotapes used to be that they were not very durable and, consequently, would wear out with repeated usage. 其中一个录影带主要弱点曾经是他们不是非常耐久性,并且,因而,不会用完以重覆的用法。[translate] areplicant 正在翻译,请等待...[translate] ...
A variety of materials can be bonded, and the physical and chemical properties of the material can be maintained at low or ultra-low temperature after bonding. It is mainly used in shoemaking, packaging, automobiles, magnetic recording materials and other fields. ...
superconductors made of rare-earth barium copper oxide (REBCO) superconducting tapes that are capable of producing high-magnetic field coils. The stronger magnetic fields generated by these coils do a better job of confining superhot plasma, so the reactor can be smaller, cheaper and take less ...
Hypalon® is the trade mark of CSM. Hypalon was developed in 1951 and since then it has become the common name for chlorosulfonated polyethylene. It is a product of DuPont Performance Elastomers, a subsidiary of DuPont. However, it is also manufactured by other manufacturers with different tra...
It also employs external electromagnets (18) that act on the magnetic cores (16) to which the screens are attached and are surrounded by return springs (19) sliding inside non-magnetic tubes (15) with closed ends. In the event of an excess of power or other anomaly the current in the ...
