摘要： The present invention provides an optical fiber distortion measuring apparatus and optical fiber distortion measuring method which make it possible to measure the amount of distortion of an optical fiber efficiently and in a short period of time. The time change waveform when a light pulse having a frequency of &ngr;1 is applied is compared with initial data (the time change waveform obtained in a case in which there is no distortion). Then, the light intensity L1 at a position Dx at which the light intensities do not agree is obtained. Next, the time change waveform is measured when a light pulse having a frequency of &ngr;2 is applied, and the light intensity L2 at position Dx is obtained. After this, the loss (resulting from distortion) in light intensities L1 and L2 is corrected, and light intensities LC1 and LC2 are obtained. Curve calculating unit 17 obtains a second-order curve which is a curve resulting from the parallel movement of a curve approximating the spectrum waveform of the initial data, and which contains the (&ngr;1, LC1) and (&ngr;2, LC2) described above. The peak frequency detecting unit 12 obtains the light frequency exhibiting a maximum value in the light intensity in the second-order curve. The distortion amount calculating unit 13 calculates the amount of distortion based on this light frequency.

摘要： An OTDR measurement device employs optical heterodyne wave detection to perform measurement on optical fibers. Optical pulses are incident on a measuring optical fiber, which in turn outputs backward scattering light. The device performs heterodyne wave detection on the backward scattering light as well as probe light whose frequency is set in proximity to a frequency of the backward scattering light, thus producing a detection voltage. The device provides a differential amplifier which performs amplification on a difference between the detection voltage and a reference voltage to produce a difference signal. An A/D converter converts the difference signal to a digital signal. Square addition is performed on the digital signal to produce a mean square signal representing property of the measuring optical fiber. Herein, calculations are performed on the mean square signal to produce a reference signal, which is then converted to the reference voltage. Herein, the reference signal is produced based on a reference value which is determined in advance such that the difference signal corresponds to an intermediate value of a voltage conversion range of the A/D converter under a state where only the probe light is incident on the device. Moreover, the reference signal is automatically changed to correct a shift of the reference voltage due to disturbance factors such as variations of temperature.
摘要翻译： OTDR测量装置采用光外差波检测来对光纤进行测量。光脉冲入射到测量光纤上，测量光纤又输出反向散射光。该装置对后向散射光进行外差波检测以及将频率设定在靠近反向散射光的频率的探测光，从而产生检测电压。该器件提供了一种差分放大器，其对检测电压和参考电压之间的差进行放大以产生差分信号。 A / D转换器将差分信号转换成数字信号。对数字信号进行平方加法，以产生表示测量光纤特性的均方根信号。这里，对均方根信号进行计算以产生参考信号，然后将其转换为参考电压。这里，参考信号是基于预先确定的参考值产生的，使得差分信号对应于在只有探测光入射到其上的A / D转换器的电压转换范围的中间值设备。此外，参考信号被自动改变以校正由于诸如温度变化的干扰因素引起的参考电压的偏移。

摘要： An astrocyte-specific drug carrier containing a retinoid derivative and/or a vitamin A analog as a constituent; a drug delivery method with the use of the same; a drug containing the same; and a therapeutic method with the use of the drug. By binding a drug carrier to a retinoid derivative such as vitamin A or a vitamin A analog or encapsulating the same in the drug carrier, a drug for therapeutic use can be delivered specifically to astrocytes. As a result, an astrocyte-related disease can be efficiently and effectively inhibited or prevented while minimizing side effects. As the drug inhibiting the activity or growth of astrocytes, for example, a siRNA against HSP47 which is a collagen-specific molecule chaperone may be encapsulated in the drug carrier. Thus, the secretion of type I to type IV collagens can be inhibited at the same time and, in its turn, fibrosis can be effectively inhibited.

摘要： A signal corresponding to a short-period change and a signal corresponding to a long-period change of a sound signal are detected, and optimal quantization is performed based on the combination of the two signals. In an ADPCM encoding apparatus (100), a differential value dn between a 16-bit input signal Xn and a decoded signal Yn-1 of one sample ago is calculated by a subtractor (102). Thereafter, the 16-bit differential value dn is adaptively quantized by an adaptive quantizing section (103), so as to be converted to a (1 to 8)-bit length-variable ADPCM value Dn. Thereafter, the ADPCM value Dn is compression-encoded by a compression-encoding section (108) to generate a signal D′n, and the signal D′n is framed by a framing section (130) and outputted. Further, in an ADPCM decoding apparatus, a framed input signal is subjected to a reverse of the aforesaid process so as to be decoded.

摘要： A pyrochlore-type oxide represented by a general formula A2B2O7-Z is prepared by precipitate formation, where A and B each represent a metal element, where Z represents a number of at least 0 and at most 1, where A contains at least one element selected from a group consisting of Pb, Sn, and Zn, and where B contains at least one element selected from a group consisting of Ru, W, Mo, Ir, Rh, Mn, Cr, and Re. Impurities are then sufficiently removed through washing and drying processes, and the pyrochlore-type oxide is calcined under controlled conditions. This allows the crystallinity of the pyrochlore-type oxide, which contained amorphous parts immediately after the production of the precipitate, to be increased so that the resistance to acid can be improved while preventing particle aggregation.
