  • Patent number: 10112255
    Abstract: The present invention relates to a thin plate bonding method or a thin plate assembly, and more particularly, to a thin plate bonding method which includes coating with a coating material after increasing a surface roughness or increasing a surface roughness through coating with a coating material, and then, conducting diffusion bonding, such that excellent bonding strength is achieved even when the diffusion bonding is performed at low temperature and low pressure, thin plate deformation by thermal stress may be prevented, and high air tightness may be obtained since the coating material fills micro-pores.

  • Patent number: 7950508
    Abstract: The present invention relates to a piston valve assembly which is used in a continuous damping control damper using magneto-rheological fluid. The piston valve assembly is coupled with an end of the piston rod, and a stopper having a flat upper surface which is surface-contacted with an upper plate is disposed between a core assembly and the upper plate, thereby properly dispersing a force applied to the piston rod. According to the present invention, the reliability and stability in the coupling between the piston rod and the piston valve assembly can be increased, thereby stably controlling the damping force of the damper. Further, the slot is formed in the core of the piston valve assembly so as to reduce the damping force in the lower speed range, thereby considerably improving the driving comport of a vehicle.

  • Patent number: 6642785
    Abstract: A power linearizer of a CDMA system preferably includes a linearization input unit for compensating a level of an input signal to remove a non-linearity of a power amplifier; an amplification controller for controlling an amplification of the power amplifier; and the power amplifier operated under the control of the amplification controller, for amplifying the power of the level-compensated input signal. By adjusting the voltage inputted to the input terminal of the voltage controlled power amplifier (VCA), the non-linearity of the VCA can be accurately compensated and the power compensation can be easily performed. In addition, the capacity of the CDMA system can be increased.
