摘要： An optical fiber manufacturing method includes placing, inside a glass pipe constituting a cladding portion, a first holding member, which is one of a pair of holding members made of glass and having a plurality of holes formed thereon, and a core rod, which includes a core forming portion serving as the core portion and includes a cladding forming portion constituting the cladding portion, in such a way that the core rod is supported by the first holding member; includes filling glass particles in the gap between the inner wall face of the glass pipe and the core rod; includes placing a second holding member of the pair of holding members inside the glass pipe and holding the core rod in a sandwiched manner in between the first holding member and the second holding member; includes sealing one end portion of the glass pipe and manufacturing an intermediate object; and includes manufacturing an optical fiber using the intermediate object. The bulk density of the first holding member and the second holding member is set to be within a predetermined range with reference to the bulk density of the filling portion filled with the glass particles, and the predetermined range is determined according to the permissible variation range for the core diameter in the longitudinal direction of the optical fiber.

摘要： [OBJECT] To provide a radar device capable of detecting a position of a target in a direction orthogonal to a viewing angle.
[ORGANIZATION] In a radar device which detects a target by using a radio wave, the radar device includes: a receiving array antenna (receiving array antenna 17) where a plurality of receiving antenna elements (first receiving antenna 17-1 to eighth receiving antenna 17-8) each having a predetermined length in a first direction are arranged to be disposed in a second direction almost orthogonal to the first direction; a dispersion part (dispersion part 31) which is disposed in a vicinity of the receiving array antenna, and dispersion properties of the radio wave change with respect to the first direction; and a detection part (control and process part 15) which detects the position of the target in the first direction based on the radio wave reflected by the dispersion part.-

摘要： A method for welding a workpiece includes steps of: disposing a workpiece in a region to be irradiated with laser light from a laser apparatus; and relatively moving the laser light and the workpiece so as to cause the laser light to sweep over the workpiece while irradiating the workpiece with the laser light from the laser apparatus, thereby melting and welding an irradiated portion of the workpiece. The laser light is formed of a main beam and an auxiliary beam, at least part of the auxiliary beam being disposed anteriorly in a sweep direction, and the main beam has a power density equal to or greater than a power density of the auxiliary beam.

摘要： A pulse generating device of an in-vehicle radar configured to output a high frequency pulse including a main lobe and a side lobe includes a high frequency oscillator that generates a carrier wave of a predetermined frequency, an output variable device that adjusts an output of the high frequency oscillator, a power measuring unit that measures the output of the high frequency oscillator, a temperature measuring unit that measures an ambient temperature, a baseband pulse generating unit that generates a signal of a pulse shape, and a modulator that modulates the output of the high frequency oscillator with the signal of the pulse shape, and, when the ambient temperature is a first threshold value or less, the output or the pulse shape is adjusted so that the side lobe is a predetermined output or less.

摘要： To provide a transmission path with little loss even when a signal at a frequency of over 8 GHz is transmitted. In a transmission path 12 transmitting high-frequency signals each containing a frequency component of over 8 GHz, the transmission path 12 includes a nickel-phosphorus layer 122 containing nickel and phosphorus, and a phosphorus concentration of the nickel-phosphorus layer 122 is over 0 mass% and less than 8 mass%. Such a structure enables to provide a transmission path with little loss even when a signal at a frequency of over 8 GHz is transmitted.
