    摘要： An improvement to a scrap melting method employing an electric arc furnace, which comprises the step of heating the scrap by a powdered coal burner prior to the step of heating the scrap by the electric arc. The burning conditions are controlled so as to reduce the amount of oxidized Fe as well as the amount of NO.sub.x contained in the exhaust gases. In preferred embodiments, a pair of furnaces are employed to heat the scrap alternately by the powdered coal burner and by the electric arc.

    摘要： Disclosed are an improved method of refining steel and an apparatus for practicing the method.The refining method comprises, basically, carrying out the refining, particularly, decarburization, while stirring molten steel in the refining furnace by injecting gas thereinto, while supplying heat with a burner installed at the top of the furnace to the molten steel. According to this method, it is possible to start at an initial carbon content of the moltend steel lower than that of known AOD process, and complete the refining in a curtailed period of time and with a decreased oxidation loss of Cr. Thus, damage of refractory materials of the furnace is reduced, and the amount of Si necessary for reducing Cr-oxides in the latter stage of the refining is also reduced.Oxygen for the decarburization is supplied usually in the form of gas, but can be supplied from a solid oxygen source. In an alternative of the present method, powdery metal oxide, which is reducable equally to or more easily than Cr-oxides, is shot into the furnace through the burner or injected into the molten steel through a tuyere or an immersed lance.Preferably, the burner is of a type of variable flame length. Use of the burner disclosed here makes it possible to lengthened the flame at the former stage of the refining so that not only heat but also oxygen may be supplied to the molten steel surface of promoting the decarburization, and to shorten the flame at the latter stage of the refining so that only heat may be supplied.

    摘要翻译： 公开了一种改进钢的精炼方法和实施该方法的装置。 精炼方法基本上包括进行精炼，特别是脱碳，同时通过在熔炼炉顶部的燃烧炉中对钢水进行加热，同时在精炼炉中搅拌钢液，同时向其中注入气体。 根据该方法，可以从蜕变钢的初始碳含量开始低于已知AOD方法的初始碳含量，并且在缩短的时间段内完成精炼并且减少Cr的氧化损失。 因此，炉的耐火材料的损伤减少，并且在精炼的后期阶段还原Cr氧化物所需的Si量也减少。 用于脱碳的氧气通常以气体的形式提供，但可以由固体氧源供应。 在本方法的替代方案中，与Cr-氧化物同等或更容易还原的粉末金属氧化物通过燃烧器喷射到炉中，或通过风口或浸入式喷枪注入钢水中。 优选地，燃烧器具有可变火焰长度的类型。 这里公开的燃烧器的使用使得可以在炼制的前一阶段延长火焰，使得不仅可以向钢水表面提供热量而且还可以提供氧气以促进脱碳，并且在后一阶段缩短火焰 的精炼，使得仅可以提供热量。

    摘要： In an electronic musical apparatus, a media ID (MD1, MD2, MD3, MD4, MD5) is associated with each recording media of a memory card 8, hard disk device 10, flash memory ROM 11, CD-ROM 12 and internet 15. Each media ID is encrypted to be recorded on a different position in a ROM 2. Upon reading a music content, the media ID of the corresponding recording media is decoded to decode the music content based upon the media ID and the secret key, and then, the resultant is temporarily stored in a RAM 3. Upon writing a music content, it is encrypted based upon the media ID corresponding to a recording media and the secret key, and the content in the RAM 3 is deleted. This makes cryptanalysis hard to thereby enhance a protection level of a music content in an electronic musical apparatus.

When assignment of waveform data to a key range including one or more keys of a keyboard is edited, the assignment state of the waveform data is displayed, and a mode setting operation of an operating unit is allowed in response to display of the assignment state of the waveform data. Waveform selection mode is set in response to operation of the operating unit by the user. When a key of the keyboard is operated in waveform selection mode, waveform data assigned to the operated key is selected, and an assignment state of the selected waveform data is allowed to be editable.
