    • A combined magnetic tape head having a recording head and a reproducing head disposed in a side by side relationship with a recessed wedge shaped area therebetween. A shielding plate is interposed between the heads to reduce cross feed therebetween. The top portion of the shielding plate is bent into L-shape so that the bent tip confronts the recording head. The remainder of the wedge shaped area is covered with a resin material, or an auxiliary plate can be positioned over the plate extending between the heads. In order to maintain the combined head free from dust accumulation, the top portion of the L-shaped shielding plate or the auxiliary plate is tapered so that it has a substantially trapezoidal cross-section with either straight or curved inclining sides.
    • 一种组合的磁带头,具有记录头和再现头,它们与它们之间的凹形楔形区域并排地设置。 屏蔽板插入在头部之间以减少它们之间的交叉进给。 屏蔽板的顶部弯曲成L形,使得弯曲的尖端面对记录头。 楔形区域的其余部分被树脂材料覆盖,或者辅助板可以位于在头部之间延伸的板上。 为了保持组合的头部没有灰尘积聚,L形屏蔽板或辅助板的顶部是锥形的,使得其具有基本上梯形的横截面,其具有直的或弯曲的倾斜侧面。

    • The infrared absorption filter of the present invention has a transmittance of not higher than 30% in the near-infrared region in the wavelength range of 800 to 1100 nm; a difference of 10% or less between a maximum value and a minimum value of transmittance in the visible light region in the wavelength range of 450 to 650 nm; and a transmittance of not lower than 50% at a wavelength of 550 nm, the filter being so excellent in environmental stability that after being left to stand in the air atmosphere at a temperature of 60° C. and a humidity of 95% for 1000 hours, the filter can maintain said spectral property in said range. Consequently, when used for a plasma display or the like, the filter can absorb the unwanted infrared rays radiated from the display, resulting in preventing erroneous operation of a remote control using infrared radiation even in such a high-temperature and high-humidity environment. The filter is gray in color so that when placed in front of a display, the color originated in the display can be seen without discoloration.
    • 本发明的红外线吸收滤光片在800〜1100nm的波长区域的近红外区域的透射率为30%以下; 在450〜650nm的波长范围内的可见光区域的透射率的最大值和最小值之间的差为10%以下; 并且在波长550nm下的透射率不低于50%,该过滤器的环境稳定性非常优异,在空气气氛中在60℃的温度和95%的湿度下放置1000 小时,过滤器可以将所述光谱特性保持在所述范围内。 因此,当用于等离子体显示器等时,滤光器可以吸收从显示器辐射的不想要的红外线,从而即使在这样的高温高湿环境下也能防止使用红外辐射的遥控器的错误操作。 过滤器的颜色为灰色,因此当放置在显示器的前面时,可以看到来自显示屏的颜色没有变色。

    • The present invention is concerned with a high water-absorbent resin composition, produced by forming a composite by fusing or fixing a thermoplastic resin onto a surface of a high water-absorbent resin via an adhesive binder or directly, wherein the composition comprises from 1 to 100 parts by weight of the thermoplastic resin, based on 100 parts by weight of the high water-absorbent resin.When the high water-absorbent resin composition of the present invention is used, it is possible to securely adhere a high water-absorbent resin to a fibrous base material, so that a water-absorbent material which stably retains the high water-absorbent resin even after absorbing water can be obtained. Accordingly, the base materials, such as fibrous base materials, can retain more amount of high water-absorbent resin than those of conventional water-absorbent materials. Thus, it is possible to provide water-absorbent composites suitable for various applications, including hygienic materials, such as paper diapers and sanitary napkins, and agricultural, horticultural, food, and other industrial materials.
