A bare optical fiber manufacturing method includes applying an ultraviolet curable resin applied around an optical fiber; and irradiating the ultraviolet curable resin with ultraviolet light emitted from semiconductor ultraviolet light emitting elements, by use of an ultraviolet irradiation device having plural ultraviolet irradiation units each having plural positions where the ultraviolet light is emitted toward the ultraviolet curable resin, the plural positions being arranged on the same circle, the plural ultraviolet irradiation units being arranged in a traveling direction of the optical fiber such that the optical fiber passes centers of the circles, at least two of the plural ultraviolet irradiation units being differently arranged with respect to circumferential direction angles thereof around an axis that is the traveling direction of the optical fiber.

Bare optical fiber manufacturing method

An object of the invention is to provide a user with information that serves as a material for determining whether an image generated by processing including a neural network is valid. A reception signal output by an ultrasonic probe that has received an ultrasonic wave from a subject is received, and an ultrasonic image is generated based on the reception signal. A trained neural network receives the reception signal or the ultrasonic image, and outputs an estimated reception signal or an estimated ultrasonic image. A validity information generation unit generates information indicating validity of the estimated reception signal or the estimated ultrasonic image by using one or more of the reception signal, the ultrasonic image, the estimated reception signal, the estimated ultrasonic image, and output of an intermediate layer of the neural network.

A small-size high-power terahertz oscillator achieves a stable oscillation in a terahertz frequency band even at room temperature. The high-power terahertz oscillator has a structure in which a bow-tie antenna is disposed on a substrate, a cavity resonator, which includes two cavities, is disposed at a power supply portion of the bow-tie antenna, and a resonant tunneling diode (RTD) is disposed along a bottom of a wall of the cavity resonator, which defines the two cavities, and stably oscillates waves in the terahertz frequency band at room temperature by using the RTD, the bow-tie antenna and the cavity resonator.

The ultrasonic image pickup apparatus includes a transmission/reception control unit that transmits an ultrasonic wave by applying a DC bias voltage and an AC driving voltage between electrodes of the electrostatic capacity type micro-machined ultrasonic transducer and picks up an image by transmitting and receiving two or more kinds of ultrasonic waveforms which have different signs, amplitudes, or phases from each other for one scanning line. In addition, as the AC driving voltage, the ultrasonic image pickup apparatus uses a voltage waveform that is obtained by adding a high frequency pulse waveform and a low frequency waveform that has a longer cycle than that of the high frequency pulse waveform and has such a voltage amplitude as makes the total voltage of the low frequency waveform and the DC bias voltage is equal or smaller than a pull-in voltage.

Provided is an optical fiber ribbon and an optical fiber cable, which are adaptable to manufacture at a high velocity, in the intermittent connecting type optical fiber ribbon obtained by adhering and connecting adjacent colored optical fibers by intermittent connecting portions. In an optical fiber ribbonof the present invention, since, in addition to polyol having a weight average molecular weight in a specific range, rheology control agent is contained in a specific range in a material forming an intermittent connecting portion, the Newtonian region between a low shear rate region and a high shear rate region of the material forming the intermittent connecting portioncan be adjusted. Thus, scattering of the material due to a centrifugal force generated by rotation of an application roll that applies the material at the time of manufacture and the like can be suppressed, and the application amount to colored optical fibercan be stabilized. In addition, the optical fiber ribboncan maintain suppression of such scattering and the like even in the manufacture at a high linear velocity.

A method for manufacturing an intermittent bonding type optical fiber ribbon which is capable of forming non-connection portions and intermittent connection portions between adjacent coated optical fibers formed into an optical fiber ribbon by performing a laser processing for the ribbon through irradiation with a pulse laser light, thereby making it possible to rapidly form the intermittent connection portions and the non-connection portions while maintaining high linear velocity of the coated optical fiber. The non-connection portions and the intermittent connection portions are formed in the obtained intermittent bonding type optical fiber ribbon through the irradiation with the pulse laser light, so the intermittent bonding type optical fiber ribbon becomes the intermittent bonding type optical fiber ribbon, which is capable of securing operability during collective connection and surely being subjected to an intermediate branching without damaging cable characteristics during high density mounting.

An optical fiber ribbon is intermittently connected in a length direction by an intermittent connection which includes a polyol having a weight-average molecular weight of 3000 to 4000 in a specific amount relative to the entire intermittent connection and which has Young's modulus at 23&#xb0; C. within a specific range. When collectively unitizing optical fiber ribbons to form an optical fiber cable, an optical fiber ribbon is formed which maintains advantages of the optical fiber ribbon and which prevents cracks of the intermittent connection and detachment of the intermittent connection from a colored optical fiber core when the cable is subjected to repetitive ironing.

There is provided a technique for obtaining a high-quality image by extracting only a nonlinear component with high accuracy in ultrasonic imaging using an amplitude modulation method of THI. By removing a fundamental wave component with high accuracy by making the influence of electrical distortion due to analog amplification on the echo signals of ultrasonic waves having different sound pressure levels approximately the same, only the nonlinear component is extracted with high accuracy. For example, the above influence is made to be the same by controlling the amplification factor of an amplification section. In addition, the above influence is made to be the same by restoring the digital data with a filter.

There is provided an ultrasound imaging apparatus that can reduce vertical stripes even though a transmission interval is widened for high speed imaging. When a receiving unitreceives an instruction to perform a high speed imaging mode, an aperture synthesizing unitadds a predetermined number (N) of phase outputs obtained from the reflected ultrasonic waves of individual transmission beams at the same received focal points to reduce the occurrence of stripes on an image. In order to generate N phase outputs at each of the received focal points, a control unitfinds a necessary number (M) of the reception scanning lines to be set by the reception beam former, and notifies the reception beam formerof the number.

When a key for directly transferring from the screen of a 'video mode' of tape reproduction to the screen of memory stick reproduction is separately arranged, the ratio of an occupation area of the key on the screen is increased. Therefore, a setting operation is performed such that a stop key () is displayed when the 'video mode' is set and no memory stick is mounted as shown in FIG.A, and when the tape is being reproduced as shown in FIG.C. In contrast to this, the setting operation is also performed such that a switching key () for transferring to the reproducing screen of the memory stick of FIG.D is displayed when the 'video mode' is set and no tape is being reproduced and the memory stick is mounted as shown in FIG.B.
