    • The present invention relates to a method for molding a high thermal resistant sound-absorbing substance which is mounted on an engine cylinder block of a vehicle and an upper vehicle body panel of a muffler by using sound-absorbing material consisting of 20-80 parts by weight of fiber materials with a limited oxygen index (LOI) of 25% or more and a thermal resistant temperature of 200°C or greater and 20-80 parts by weight of thermosetting resins with a thermal resistant temperature of 200°C or greater and, more specifically, to a method for molding a high thermal resistant sound-absorbing substance comprising: a release agent spraying step of spraying a releasing agent to the inner space of a hot-working mold; a hot-working compressed molding step of fixing a shape; and a cool-working compressing step of stabilizing the shape. The high thermal resistant sound-absorbing substance molded by the method is able to reduce the interior noise of a vehicle by preventing a radiated noise generated from an engine and exhaust system from being transferred to the inside of the vehicle through a vehicle body panel; is able to maintain a shape even in the hot environments of 200°C or greater generated in the engine and the exhaust system; and is able to satisfy the flame retardant of UL 94V-0.
    • 本发明涉及一种高耐热吸音物质的成型方法,该方法通过使用由20-80份的吸音材料组成的吸声材料安装在车辆的发动机气缸体和消声器的上部车体面板上 具有有限氧指数(LOI)为25%或更高,耐热温度为200℃或更高的纤维材料的重量和耐热温度为200℃或更高的热固性树脂为20-80重量份,以及 更具体地,涉及一种用于模制高耐热吸声材料的方法,包括:将脱模剂喷射到热加工模具的内部空间的脱模剂喷射步骤; 固定形状的热压缩成型步骤; 以及稳定形状的冷却压缩步骤。 通过该方法模制的高耐热吸音物质能够通过防止从发动机和排气系统产生的辐射噪声通过车体面板传递到车辆内部而降低车辆的内部噪声; 即使在发动机和排气系统中产生的200℃以上的高温环境中也能够保持形状; 并能够满足UL 94V-0的阻燃性。

    • A directionally-sensitive device (10) for detecting and processing vibration waves includes an array of polymeric optical waveguide resonators (28) positioned between a light source (24), such as an LED array (24), and a light detector (26), such as a photodiode array (26). The resonators (28) which are preferably oriented substantially perpendicularly with respect to incoming vibration waves, vibrate when a wave is detected, thus modulating light signals that are transmitted between the light source (24) and the light detector (26). The light detector (26) converts the modulated light into electrical signals which, in a preferred embodiment, are used to drive either the speaker of a hearing aid (32) or the electrode array (39) of a cochlear implant. The device (10) is manufactured using a combination of traditional semiconductor processes and polymer microfabrication techniques.
