摘要:
A butt welding system and a butt welding method of steel plate by which the quality of a product can be ensured. Butting portions of blank members (1,2) to be joined together are butted and a predetermined butting load is applied to the butting portion, wherein the blank members (1,2) are moved relatively in the direction of the welding line thus matching the butting portions. Protrusions and recesses formed on each butting portion of each blank member (1,2) are flattened, whereby linear precision at each butting portion of each blank member (1,2) is enhanced as compared with a case where the butting portions are not matched. Since the gap is reduced extremely at the butting portion, welding is facilitated at the butting portion. Good welding beads are thereby obtained at the butting portion and the quality of a product is ensured.

A water-in-oil (W/O) emulsion ink which is suitable for use in inkjet printing and is low in viscosity and superior in storage stability is provided. The ink comprises an oil phase and a water phase emulsified in the oil phase using a nonionic surfactant, in which the water phase contains a salt of at least one metal selected from potassium or calcium. The metal salt is preferably a calcium salt, and particular preferably calcium chloride. The nonionic surfactant is preferably a polyglycerin fatty acid ester, and particularly preferably an esterification product of a polyglycerin and a hydroxy fatty acid. Preferably, the ink comprises 40-99 mass % of the oil phase and 60-1 mass % of the water phase, and contains a polyglycerin fatty acid ester in an amount of 0.5-40 mass % based on the total of the ink.

A portable electronic device having an RFID function has an RFID antenna having a planar coil formed by winding a conductor. The RFID antenna is a loop antenna having a loop diameter corresponding to RFID with a strong electromagnetic field characteristic, and has an antenna pattern where a part of its coil turn which is other than an innermost coil turn is placed inward of the innermost coil turn. The antenna pattern can be provided by bending or branching a part of a coil turn of the conductor which is other than the innermost coil turn in such a way that the part of the coil turn is laced inward of the innermost coil turn, thereby ensuring compensation for the magnetic field strength at the center portion of the antenna and achieving excellent communications without a non-communicatable area even with the RFID having a slight electromagnetic field characteristic.

A WDM (Wavelength Division Multiplex) terminal device located in a WDM network includes a multiplexing unit that multiplexes a wavelength of a client signal having a single wavelength or a wavelength of at least one of a first plurality of client signals whose wavelengths are multiplexed, to wavelengths of a second plurality of client signals received with their wavelengths being multiplexed, and transmits the second plurality of client signals. Thus, the WDM terminal device can multiplex wavelengths of a plurality of client signals received from a metro WDM terminal device located at a distant place, to a wavelength of another client signal without separating the plurality of client signals by each wavelength, thereby achieving accommodation of a plurality of client signals whose wavelengths are multiplexed, at low cost.
