  • Patent number: 9496540
    Abstract: Disclosed herein is a plate-shaped secondary battery used as a unit cell for middle- or large-sized battery pack, the secondary battery having an electrode assembly, which can be charged and discharged, mounted in a sheet-shaped battery case including a metal layer and a resin layer in a sealed state, the electrode assembly having electrode terminals protruding outside a sealing part of the battery case, wherein at least one of the electrode terminals is provided at a position spaced a predetermined distance from the sealing part with a self cutting part having a vertical sectional area less than that of the remaining part of the at least one electrode terminal such that the self cutting part can break first when overcurrent flows in the secondary battery.

  • Patent number: 9461436
    Abstract: The present invention relates to a pulse laser device, and more particularly, to a pulse laser device which can be operated in a burst mode, in which the output of a low-output laser generator is adjusted so as to enable the uniform control of the profile of the peak output of a final output optical pulse train, and in a variable burst mode, in which the profile of the final output optical pulse train can be controlled into an arbitrary waveform.

  • Patent number: 9077147
    Abstract: Disclosed is a burst mode oscillation method for burst mode oscillation by controlling the peak output of light pulses in a laser system. The burst mode oscillation apparatus includes a seed beam generator which receives electrical input signals having different pulse widths, modulates pulse widths and amplitudes of outputs in output light according to the received electrical input signals, and outputs the modulated pulse light, an amplifier which amplifies the modulated pulse light and outputs amplified pulse light, and a non-linear wavelength converter which can control wavelength-converted output light according to the amplitudes of the peak output changed through the pulse widths of the amplified pulse light.
