    • PURPOSE:To enable to measure a degree of vacuum correctly by making a jet of vapor by raising the temperature of mercury or oil with the normal temperature and low vapor pressure and discharging gas from the high vacuum side to the low vacuum side by this operation. CONSTITUTION:In measuring the degree of vacuum by a Macleod gage, the pressure P is calculated by a calculating formula of P=hXv/VTorr (h: height of mercury column, v: volume of C, V: volume of A). Then, V of the volume of A is set prescribedly beforehand and the minimum point of curvature of the graph is calculated and the value of the least P is calculated from the least values of v and h to obtain 10 mm.

    • PROBLEM TO BE SOLVED: To improve the subjective quality of decoding signal by properly adjusting the dynamic range of spectrum inserted in a technique for replacing a spectrum of a certain band with a spectrum of another band. SOLUTION: A deformation information estimation unit 303 estimates deformation information by checking a way of deformation by use of a first spectrum S1(k) of the band 0≤k≤FL (k is the frequency of each sub-band). A deformation unit 304 deforms the first spectrum S1(k) of the band 0≤k≤FL by use of the estimated deformation information to thereby generate a deformed first spectrum S1'(j, k) (j is an index for identifying each deformation process). An extended band spectrum encoding unit 114 estimates a spectrum to be contained in the higher range (FL≤k COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:通过适当地调整插入在用另一频带的频谱替换特定频带的频谱的技术中的频谱的动态范围来提高解码信号的主观质量。 解决方案:变形信息估计单元303通过使用频带0≤k≤FL(k是每个子带的频率)的第一频谱S1(k)检查变形方式来估计变形信息。 变形单元304通过使用估计的变形信息使频带0≤k≤FL的第一频谱S1(k)变形,从而生成变形的第一频谱S1'(j,k)(j是用于识别各变形的指标 处理)。 扩展频谱频谱编码单元114通过使用变形的第一频谱S1'(j,k)来估计包含在第一频谱S1(k)的较高范围(FL≤k
