    • The procedure of the present invention may be applied to mold a composite material having a predetermined configuration. The first step of the present procedure is to form the dimples of the core in accordance with a super-plasticizing molding procedure, so that the dimples may exhibit a height higher than that in its final configuration which corresponds with the above-described predetermined configuration, and its top surface is formed in a convexed configuration. Then, pressure is applied to the core to flatten it by forcibly deforming it prior to or at the moment of jointing the skins of the predetermined configuration, so that the dimples may come into contact with the internal surface of the skin at their top surfaces. Thereafter or simultaneously with this operation, the skins of the predetermined configuration are jointed. The composite material formed exhibits an increased operational reliability and an improved dimensional precision in its configuration, without causing the dimples top surface to be out of contact due to a design allowance.
    • 本发明的方法可以用于模制具有预定构型的复合材料。 本方法的第一步是根据超塑化模制步骤形成芯的凹坑,使得凹坑可以表现出高于其最终构造的高度,其对应于上述预定构型, 并且其顶表面形成为凸形构造。 然后,通过在将预定构造的表皮接合之前或期间强制地将其施加到芯上以使其平坦化,使得凹坑可以在其顶表面处与皮肤的内表面接触。 此后或同时进行该操作,将预定构造的表皮接合。 形成的复合材料表现出增加的操作可靠性和其配置的改进的尺寸精度,而不会由于设计余量而导致凹坑顶表面不接触。

    • A CPU of an effector calculates envelopes of an impulse response waveform from sample data of impulse response waveform data supplied from a microphone via an A/D converter circuit. Next, CPU detects a section during which a slope of the detected envelopes takes a value near “0” during a predetermined time or longer. CPU calculates an average value of sample data during the detected section to correct a DC offset. Thereafter, CPU acquires a maximum value of absolute values among the sample data during the detected section, and determines this maximum value as a background noise component value. The background noise components are removed from each sample data constituting the impulse response waveform data.
    • 效应器的CPU通过A / D转换器电路从麦克风提供的脉冲响应波形数据的样本数据中计算脉冲响应波形的包络。 接下来,CPU在预定时间或更长时间内检测检测到的信封的斜率在“0”附近取值的部分。 CPU在检测到的部分中计算采样数据的平均值,以校正直流偏移。 此后,CPU在检测部分期间获取采样数据中的绝对值的最大值,并将该最大值确定为背景噪声分量值。 从构成脉冲响应波形数据的每个采样数据中去除背景噪声分量。
