    • A first absorbent comprising: synthetic fibers and/or natural fibers; water-absorbing fibers; and ultrafine fibers, characterized by being obtained by mixing all these fibers together, carding the mixture, and then needle-punching the carded mixture; a second absorbent which is a laminated nonwoven fabric comprising: synthetic fibers and/or natural fibers; and water-absorbing fibers, characterized by comprising one nonwoven fabric layer comprising fibers having a higher average fineness and another nonwoven fabric layer comprising fibers having a lower average fineness; and a third absorbent comprising flame-retardant fibers and (flame-retardant) water-absorbing fibers, characterized by being obtained by mixing all these fibers together, carding the mixture, and then needle-punching the carded mixture. The absorbents are excellent not only in liquid absorption but in liquid retention and dimensional stability. They are suitable for use as absorbents for ink-jet printers.
    • 第一种吸收剂,包括:合成纤维和/或天然纤维; 吸水纤维; 和特细纤维,其特征在于将所有这些纤维混合在一起,将混合物梳理,然后针刺梳理的混合物; 第二吸收剂,其为层压无纺布,其包含:合成纤维和/或天然纤维; 和吸水纤维,其特征在于包括一层非织造织物层,其中包含具有较高平均细度的纤维的非织造织物层和包含平均细度较低的纤维的另一非织造织物层; 以及包含阻燃纤维和(阻燃)吸水纤维的第三种吸收剂,其特征在于将所有这些纤维混合在一起,将混合物梳理,然后针刺梳理的混合物。 吸收剂不仅在液体吸收方面,而且在液体保持性和尺寸稳定性方面都是优异的。 它们适用于喷墨打印机的吸收剂。

    • A vertically anisotropic medium or a vertical recording system for conducting unoriented recording. The system has a terminal for receiving binary signals that are to be recorded, a ring head for causing magnetic change in the medium, and a recording current generating circuit for generating a recording current that drives the ring head. The recording current is a sequence of fine pulses whose polarities change in response to the direction of change of polarities of the binary signal, and nonzero intervals of a neutral level are inserted between the neighboring fine pulses having opposite polarities relative to each other. The pulses are given a duration TW which satisfies a relationship TW
    • 用于进行无取向记录的垂直各向异性介质或垂直记录系统。 该系统具有用于接收要记录的二进制信号的终端,用于引起介质中的磁变化的环形头,以及用于产生驱动环形头的记录电流的记录电流产生电路。 记录电流是其极性响应于二进制信号的极性变化方向而改变的精细脉冲序列,并且中性电平的非零间隔被插入相对于彼此具有相反极性的相邻细微脉冲之间。 脉冲被给予持续时间TW,其满足关系TW
