    • There is proposed a battery with a large capacity that excels in safety. The safety valve is disposed to cover at least a portion of the center line of the lid plate between the pair of terminals for the positive electrode and the negative electrode. The distance from the center line of the lid plate to end portions of the components to be energized on the safety valve side is equal to or less than the distance from the center line of the lid plate to the outermost circumference of the safety valve. The shadow area obtained by projecting an opening portion of the safety valve in operation onto the plane of the lid plate does not overlap with the respective shadow areas obtained by projecting the electrically connected components, such as the external output terminals for the positive electrode and the negative electrode, onto the plane of the lid plate.

    • A speech spurt detecting apparatus for detecting speech spurts in a voice signal has a storage for storing an input voice signal. A decision portion determines speech spurt sections and mute sections using a threshold value and sets one of the mute sections at a latter part of a hangover time. A mute level statistical processor estimates the noise distribution of a signal in the mute sections. A speech spurt detecting threshold value decision portion receives the average and the variance of the noise distribution from the mute level statistical processor and approximates the noise distribution to a gamma distribution to decide a speech spurt detecting threshold. A speech spurt transmitting portion outputs the voice signal in the speech spurt sections from the storage. A speech spurt level statistical processor carries out statistical processing of the speech spurt sections. The speech spurt detecting threshold value decision portion detects an error of the speech spurt detecting threshold value using the speech spurt level statistical processor and the mute level statistical processor and resets the speech spurt detecting threshold value to its initial value if the error exceeds a predetermined value. The speech spurt detecting threshold value decision portion increases the speech spurt detecting threshold value at a fixed rate in each of the speech spurt sections, and computes (the average).sup.2 /(the variance) to obtain an adjusting coefficient and computes (the adjusting coefficient).times.(the average) to obtain the speech spurt detecting threshold value.
    • 用于检测语音信号中的语音喷发的语音突发检测装置具有用于存储输入语音信号的存储器。 决定部分使用阈值确定语音突发部分和静音部分,并且在宿醉时间的后半部分设置静音部分中的一个。 静音级统计处理器估计静音部分中的信号的噪声分布。 语音突发检测阈值判定部分从静音级统计处理器接收噪声分布的平均值和方差,并将噪声分布近似为伽马分布,以决定语音突发检测阈值。 话音突发发送部分从存储器输出语音突发部分中的语音信号。 语音突发等级统计处理器执行语音突发部分的统计处理。 语音突发检测阈值判定部使用语音突发级统计处理器和静音级统计处理器来检测语音突发检测阈值的误差,并且如果误差超过预定值则将语音突发检测阈值重置为其初始值 。 语音突发检测阈值判定部分在每个语音突发部分中以固定速率增加语音突起检测阈值,并且计算(平均)2 /(方差)以获得调整系数并计算(调整系数 )x(平均),以获得语音突发检测阈值。
