This invention relates to a water-soluble fiber and a method of manufacturing the fiber. The water-soluble fiber of the invention is composed of a high molecular compound with a weight average molecular weight of not less than 10,000, which high molecular compound is obtainable by reacting a polyalkylene oxide compound, which is obtainable by addition polymerization of an ethylene oxide-containing alkylene oxide and an organic compound containing two active hydrogen atoms, with a polycarboxylic acid, an anhydride thereof, a lower alkyl ester thereof, or a diisocyanate and is manufactured by spinning the same high molecular compound. The water-soluble fiber of the invention is not only high in elongation and tensile strength but is readily soluble in water.

摘要:
In a speech synthesizer, each frame for generating a speech waveform has an expansion degree to which the frame is expanded or compressed in accordance with the production speed of synthetic speech. In accordance with the set speech production speed, the time interval between beat synchronization points is determined on the basis of the speed of the speech to be produced, and the time length of each frame present between the beat synchronization points is determined on the basis of the expansion degree of the frame. Parameters for producing a speech waveform in each frame are properly generated by the time length determined for the frame. In the speech synthesizer for outputting a speech signal by coupling phonemes constituted by one or a plurality of frames having phoneme vowel-consonant combination parameters (VcV, cV, or V) of the speech waveform, the number of frames can be held constant regardless of a change in the speech production speed. This prevents degradation in the tone quality or a variation in the processing quantity resulting from a change in the speech production speed.

Disclosed is an aluminum alloy sheet having a chemical composition of an Si-containing Al--Mg--CU alloy. The aluminum alloy sheet exhibits a streak-shaped modulated structure at a diffraction grating points of an Al--Cu--Mg--system compound in the electron beam diffraction grating image. The above mentioned streak can be generated efficiently when the alloy essentially consists of 1.5 to 3.5% by weight of Mg, 0.3 to 1.0% by weight of Cu, 0.05 to 0.6% by weight of Si, and the balance of Al and inevitable impurities, and the ratio of Mg/Cu is in the range of 2 to 7. The alloy contains 0.01-0.50% of at least one element selected from the group consisting of Sn, Cd, and In.
摘要:
Analysis of a nucleic acid samples having thousands of bases is conducted by capillary electrophoresis. The electrophoretic section is provided with a first capillary filled with an agarose gel and a second capillary filled with a polyacrylamide gel. An on-column detector is incorporated with the second capillary for optical detection. To fill a capillary with a gel, a solution is fed under high pressure from a first flow channel through a switching valve into a second flow channel connected to the capillary. To inject a sample in the capillary, a sample injector is connected to a switching valve passage, and a buffer solution is connected to the capillary through a flow channel and the switching valve. After switching the valve, the first passage is incorporated into the flow channel between the buffer solution and the capillary being filled. Then, the sample is electro-kinetically injected into the capillary. When conducting genetic polymorphism by electrophoresis, temperature control elements are provided to maintain the capillary at a predetermined temperature and a DNA sample device is provided to heat the sample to a temperature higher than a disassociation temperature thereof for directly injecting the heated sample into the capillary.
摘要:
A counter circuit which incurs a uniform number of logic changes whether the clock signal is rising or falling is used in both a first counter circuit for measuring the reference signal for horizontal scanning period and a second counter circuit for measuring signals in the vertical blanking period. Since the number of logic changes of the flip-flops with respect to the clock signal is uniform, a driving circuit for a solid-state image sensor is realized in which noise in the vertical blanking period does not appear in the video period even if by using 1H delay line.
