    • A noise suppressor suppresses noise contained in speech converted by an A/D converter into a digital signal. A sidetone level controller controls a level of a speech signal with the noise suppressed by the noise suppressor, for output as a sidetone. A D/A converter then converts a speech receiving signal with the sidetone added from a digital signal to an analog signal. Therefore, it becomes possible to prevent a level of the sidetone from being changed according to a level of the noise existing in the background of a talker, and to control the sidetone to allow the talker to talk at an appropriate volume.
    • 噪声抑制器将由A / D转换器转换的语音中包含的噪声抑制成数字信号。 侧音电平控制器控制具有由噪声抑制器抑制的噪声的语音信号的电平,以作为侧音输出。 然后,D / A转换器将具有从数字信号添加的侧音的语音接收信号转换为模拟信号。 因此,可以根据在讲话者的背景中存在的噪音的水平来防止侧音的水平变化,并且可以控制侧音以允许讲话者以适当的音量进行通话。

    • The present invention relates to a braiding yarn made of expanded graphite for a gland packing which is to be used in a shaft seal part of a fluid apparatus or the like. In the braiding yarn made of expanded graphite of the invention, a braiding yarn base material of the inner-reinforce type is used in which a plurality of reinforcing fibers are embedded in the longitudinal direction in an expanded graphite tape of a predetermined width, with forming gaps in the width direction. A twisting process is performed in a state where both the end portions in the width direction of the expanded graphite tape are bent so that both the end portions in the width direction of the expanded graphite tape are directed toward the inner side in the width direction of the base material. Alternatively, while twisting the base material both the end portions in the width direction of the expanded graphite tape are bent so that both end portions in the width direction are directed toward the inner side in the width direction. According to the invention, flaking of expanded graphite particles during a process of twisting the braiding yarn made of expanded graphite is reduced or prevented from occurring.
    • 本发明涉及一种用于用于流体装置等的轴密封部分中的用于压盖填料的膨胀石墨的编织纱线。 在由本发明的膨胀石墨制成的编织纱中,使用内加强型编织纱基材,其中多根增强纤维沿长度方向嵌入预定宽度的膨胀石墨带中,成型 宽度方向的间隙。 在膨胀石墨带的宽度方向上的两端部弯曲的状态下进行加捻处理,使得膨胀石墨带的宽度方向上的两端部朝向宽度方向的内侧 基材。 或者,在使膨胀石墨带的宽度方向上的两端部扭曲的同时,使宽度方向的两端部朝向宽度方向的内侧。 根据本发明,减少或防止在由膨胀石墨制成的编织纱线加捻过程中膨胀石墨颗粒的剥落。

    • The present invention provides a gland packing in which a phenomenon where reinforcing fibers protruding from ends of adjacent braiding yarns overlap with each other, and the over-lapping reinforcing fibers are interposed over the whole range between expanded graphite tapes of the adjacent braiding yarns to form a leakage path can be reduced. In the gland packing 4, ends 1a, 1b in the width direction of each of the braiding yarns 3A to 3H constituting the gland packing are directed to the inner side in the width direction, and the reinforcing fibers 2A to 2H protruding from the ends 1a, 1b are confined to the inner side of the braiding yarns 3A to 3H.
    • 本发明提供一种压盖填料,其中从相邻编织纱线的端部突出的增强纤维彼此重叠的现象,并且覆盖增强纤维被插入相邻编织纱线的膨胀石墨带之间的整个范围内以形成 可以减少泄漏路径。 在压盖填料4中,构成压盖填料的各编织纱线3A〜3H的宽度方向的端部1a,1b朝向宽度方向的内侧,从端部1a突出的增强纤维2A〜2H 1b限制在编织线3A〜3H的内侧。
