摘要:
A signal processor includes a period detection section which detects that a period is currently used for communication of a frame; a pattern detection section which detects, from the received signal, a first signal pattern by which the end of communication of the frame is recognized; and an output processing section which outputs the received signal to a controller, configured to instruct, upon detection of the first signal pattern in the period being currently used for communication of a frame, the controller to halt startup of communication action of the next frame, until the period being currently used for communication of a frame comes to the end, to thereby reduce an event such that frames are transmitted from a plurality of communication devices simultaneously, and to thereby allow the communication action for the next frame to proceed correctly.

A slab type laser apparatus has a slab type gas laser medium part formed in a region defined by a pair of electrode flat plates oppositely disposed in parallel with each other in a space to be filled with a gas laser medium which is excited by high-frequency electric power. The apparatus includes an oscillator part including a pair of resonator mirrors oppositely disposed with a part of the gas laser medium part in between, and for amplifying a laser beam to have predetermined light intensity to emit the laser beam, and the amplifier part including a plurality of return mirrors oppositely disposed with a part of the gas laser medium part in between. The incident laser beam goes and returns plural times between the return mirrors, and the laser beam is amplified to have predetermined power.

In an extreme ultra violet light source apparatus that exhausts debris including fast ions and neutral particles by the effect of a magnetic field, neutral particles emitted from plasma are efficiently ionized. The extreme ultraviolet light source apparatus includes: a plasma generating unit that generates plasma, that radiates at least extreme ultra violet light, through pulse operation; collective optics that collects the extreme ultra violet light radiated from the plasma; a microwave generating unit that radiates microwave through pulse operation into a space in which a magnetic field is formed to cause electron cyclotron resonance, and thereby ionizes neutral particles emitted from the plasma; a magnetic field forming unit that forms the magnetic field and a magnetic field for trapping at least ionized particles; and a control unit that synchronously controls at least the plasma generating unit and the microwave generating unit.

An extreme ultra violet light source apparatus in which both a mechanism of supplying a droplet target to a laser application position at a high speed and a mechanism of trapping charged particles generated from plasma are managed without disturbing a track of the target. The apparatus includes: a target nozzle that injects a target material toward a plasma generation point; an electric charge supply unit that charges the injected target material; an acceleration unit that accelerates the charged target material; a laser oscillator that applies a laser beam to the target material at the plasma generation point to generate plasma; and electromagnets that form a magnetic field at the plasma generation point such that the magnetic field has substantially straight lines of magnetic flux in substantially parallel with a traveling direction of the target material in the track of the target material.

A water-based ink for ink-jet recording may include a benzotriazole type compound for preventing corrosion of a metal in an ink ejection portion of an ink-jet head, and a coloring agent having a divalent metal in a structure thereof, and a polymer containing a polymerization unit having at least two carboxyl groups in an ethylene chain unit. The generation of a precipitate by reaction between the divalent metal and the benzotriazole type compound may be suppressed without using a sequestering agent. The ink may have an excellent corrosion inhibiting effect and an ink ejection stability effect.
