Processing is performed to make a user to certainly read information, e.g., a document, to be read by the user. In the processing, a database of an information management server stores information to be read by the user, an ID identifying the information, and status information identifying whether the information is not yet read by the user. When the user wishes to operate an apparatus in a system, the operation of the apparatus is restricted if the information to be read by the user is unread. If the information to be read by the user is already read, the operation of the apparatus is permitted.

A high-frequency electric resistance welding method combined with the irradiation of a laser beam in which a workpiece is continuously fed and opposed edges of the workpiece are formed into a wedge shape by causing them to converge as they are butted against each other, and the butted edges are melted by heating them with high-frequency resistance heating and a laser beam, to weld the butted edges. The laser beam is projected against the range of over 30% and below 80% of the thickness of the butted edges including the central portion of the thickness to melt the butted edges by the combined heating action of the laser beam and high-frequency current. The corners are heated and melted by means of high-frequency electric resistance heating, so that the butted edges of the workpiece can be melted uniformly through the entire range of thickness.

Sheet bars are effectively joined while they are traveling and subjected to continuous hot rolling without causing defects in quality and without requiring large expensive apparatus such as a swing roller etc. The present invention is to provide a continuous hot rolling method and apparatus in which the tail of a preceding sheet bar is butted to the top of a succeeding sheet bar between the rough and finishing mills on a continuous hot rolling line, and the butted portion is welded from the upper surface of the sheet bars by means of laser beam or plasma arc while the sheet bars are traveling. According to the present invention, it is possible to join sheet bars from the upper surface in a short period of time without stopping the sheet bars and without causing splashes and burrs, before the sheet bars are subjected to continuous finish rolling. Since the welded apparatus does not interfere with the sheet bar conveyance table, hot strips of high quality can be effectively manufactured by the economical apparatus.

In order to obtain a high-power laser beam with a high beam quality with use of a small-sized and low-cost apparatus, there has been disclosed a laser resonator which is constructed so as to produce a single high-order transverse mode laser beam, and a technique for converting the laser beam with a single high-order transverse mode into a laser beam with a high beam quality. The laser resonator is provided with a regulating plate of a high-order transverse mode which is constructed so as to produce a laser beam in a single high-order transverse mode. A phase adjusting plate inverts a phase for each region of the laser beam divided depending upon a lateral mode thereof to match the phase for each region of the laser beam, and subsequently, a traveling direction of the laser beam is changed for each position thereof by means of the first binary optics element, and further, the laser beam is converted into a parallel beam by means of the second binary optical element. The first binary optics element changes the traveling direction of the ray of the laser beam for each region thereof so that the laser beam has a desired intensity distribution on the second binary optics element.

摘要:
When the power output of a continuous wave oscillated laser is changed to a pulsed laser by Q-switching, in the conventional method of Q-switching, if the pulse repetition rate is changed, the condition of oscillated excitation is changed and the pulse waveform or pulse peak power are simultaneously changed; and therefore, a stable dulling process is impracticable.The present invention decreases the cavity loss of a laser oscillator during a pulse off by decreasing power output of the radio-frequency signal applied to the Q-switch, and consequently, controls the pulse waveform to that required for the roll dulling process. In accordance with the method of the invention, the roughness of the dulled roll surface consists of innumerable small craters and is suitable for a high speed fine dulling process.

A thin metal strip excellent in both shape and quality is produced by a continuous casting process which comprises the steps of jetting a molten metal through a nozzle onto the surface of a moving chill body maintained at a pertinent temperature range by irradiating a high density energy at a place positioned at the rear of the nozzle, and subjecting the molten metal to quenching so as to effect solidification.
