摘要： In magnetic transfer performed to transfer an information signal such as a servo signal from a master medium to a slave medium, the degradation of transfer quality caused by a failure of close contact between the master medium and the slave medium due to dust accumulated thereon is prevented. Magnetic transfer means is provided to carry out the magnetic transfer by bringing the master medium bearing information and the slave medium into close contact with each other, and applying a transfer magnetic field. Replacing means is provided to prepare a plurality of master media, and replacing the master medium after magnetic transfer is performed a predetermined number of times. Cleaning means is also provided to clean the replaced master medium by ultrasonic washing or the like.

摘要： A method for producing a tin free steel having double layers consisting of a lower layer of flatly deposited metallic chromium and an upper layer of insoluble hydrated chromium oxide which is characterized by a dissolution of soluble hydrated chromium oxide after the formation of three layers consisting of a bottom layer of metallic chromium, a middle layer of insoluble hydrated chromium oxide and an upper layer of soluble hydrated chromium oxide on a steel base by using a chromic acid electrolyte with a small amount of fluoride compound.By using this tin free steel, a welded can body can be produced at high speed without the removal of the plated layer in the welded part because this tin free steel has an excellent weldability.
摘要翻译：一种用于生产具有双层沉积金属铬的下层和不溶性水合氧化铬上层的无锡钢的方法，其特征在于在形成三层之后溶解可溶性水合氧化铬金属铬的底层，不溶性水合氧化铬的中间层和可溶性水合氧化铬的上层，通过使用具有少量氟化物的铬酸电解质在钢基体上。通过使用这种无锡钢，由于这种无锡钢具有优异的焊接性，所以可以高速度地制造焊接罐体，而不会在焊接部分中除去镀层。

摘要： Tin free steel having three layers consisting of a bottom layer of metallic chromium, a middle layer of nickel-zinc alloy containing 10 to 90 weight percent of zinc and a top layer of hydrated chromium oxide on a steel base, and a method for the continuous production of this tin free steel which comprises:(a) chromium plating a steel base to form a layer of metallic chromium and hydrated chromium oxide, (b) nickel-zinc alloy plating the chromium plated steel base by using a nickel-zinc alloy plating electrolyte sufficiently acidic to dissolve the hydrated chromium oxide and (c) forming a hydrated chromium oxide layer on the chromium plated nickel-zinc plated steel base.Instead of (b) in the above method, a cathodic treatment in an acidic solution can be carried out for the removal of hydrated chromium oxide formed during chromium plating, and thereafter nickel-zinc alloy plating can be carried out by using a known nickel-zinc alloy plating electrolyte.This tin free steel is useful for producing welded can bodies at high speed without removing the plated layer in the welded part, since it has an excellent weldability.
摘要翻译：具有金属铬底层，含有10〜90重量％锌的镍 - 锌合金的中间层和钢基上的水合氧化铬顶层的三层无锡钢，以及连续的该无锡钢的制造方法包括：（a）镀铬钢基以形成金属铬和水合氧化铬层，（b）通过使用镍 - 锌合金电镀电镀镀铬钢基体的镍 - 锌合金电解质充分酸化以溶解水合氧化铬，和（c）在镀铬的镀镍钢基体上形成水合氧化铬层。代替（b）在上述方法中，可以进行酸性溶液中的阴极处理以除去在镀铬期间形成的水合氧化铬，然后可以使用已知的镍 - 锌合金电镀电解液。由于具有优异的焊接性，所以这种无锡钢可以高效地生产焊接罐体，而不需要去除焊接部件中的镀层。
