Abstract: A continuous forming apparatus of a fiber reinforced composite includes a tension detection mechanism, a drive motor, and a drive control device. The drive control device is configured so that a material roll is rotationally driven in a delivery direction of a reinforced fiber base material during a time period from a time point of end of pressurization in a forming process to a time point of end of a pulling-out process, and is also configured to perform tension control on the reinforced fiber base material based on a detected tension value from the tension detection mechanism and a target tension value, during a time period from a time point of start of the pulling-out process to a time point of end of the pressurization in the forming process in a next forming operation.

Abstract: Extract intracorporeal sounds (such as low-frequency-range heart sounds or breath sounds) by not only reducing steady noise (such as low-frequency-range environmental sounds or noise) but also reducing unexpected noise (such as high-frequency-range cries or speaking voices). This keeps up the intracorporeal sounds (such as low-frequency-range heart sounds or breath sounds), while reducing the unexpected noise (such as high-frequency-range cries or speaking voices), using an improved adaptive filter unit and an improved nonlinear filter unit. Here, a reduction level of the unexpected noise (such as high-frequency-range cries or speaking voices) and a level of keeping up the intracorporeal sounds (such as low-frequency-range heart sounds or breath sounds) are quantitatively calculated.

Abstract: A magnetic field measuring apparatus includes a digital FLL circuit including ADC that converts a periodically changing voltage output from a SQUID according to a change in a magnetic field into a digital value, a digital integrator that integrates the digital value output from the ADC, a DAC that converts an integrated value output from the digital integrator into a voltage, a converter that converts the voltage output from the DAC into a current, and a coil that generates the magnetic field received by the SQUID, based on the current output from the converter. A calculating device calculates a digital value indicating a flux quantum based on the digital value output from the ADC when the ADC converts the periodically changing voltage output from the SQUID upon receiving the magnetic field generated by a current that is obtained by converting a voltage generated by a voltage generator.

Abstract: An object is to provide a method for producing a polysaccharide derivative without using a catalyst, a cocatalyst, or an active compound by esterification, etherification, or the like, from a polysaccharide such as cellulose as a source material, while maintaining a high molecular weight. Another object is to provide a method for producing a cellulose derivative in a separated condition directly from biomass containing lignocellulose. A method for producing a polysaccharide derivative of the present invention is characterized in that a reaction is carried out in a mixture comprising: a source material comprising a polysaccharide; an ionic liquid for which the pKa of a conjugate acid of an anion in DMSO is 12 to 19 and which is capable of producing a carbene; and a chain or cyclic ester compound or an epoxy compound. Preferably as a source material containing a polysaccharide, a biomass source material containing lignocellulose is used.

Abstract: A heart correction net according to the present invention is attached to an exterior of a heart. The heart correction net includes a first area that is a partial area included in a right ventricle side area of an entire area surrounding exteriors of ventricles; and a second area that is an area surrounding the first area in the right ventricle side area and a left ventricle side area. The first area in the heart correction net is configured to provide a lower contact pressure against a heart during a cardiac diastole than the second area.
