  • Patent number: 8826689
    Abstract: The present invention relates to an air conditioner and to an outdoor unit. More particularly, the present invention relates to an air conditioner having a plurality of indoor units, wherein said air conditioner comprises a distribution unit which is accommodated in an outdoor unit of the air conditioner and connected to the outdoor unit and indoor units, or which is separated from the outdoor unit and connected to the outdoor unit and indoor units to distribute refrigerant to the plurality of indoor units.

  • Publication number: 20130107288
    Abstract: The purpose of this invention is to avoid unnecessary print out and cut wasteful consumption of resources and electricity. A printer receives a command indicating whether or not a user does not need to print out images such as advertisements on web pages. If a drawing command acquired by analyzing received print data is image, the printer determines whether or not the command is to draw images based on the user's choice and execute a drawing process along with the command from the user. Consequently, the printer can print out text information with eliminating image information which is noise for the user and can eliminate print out for unnecessary image information.

  • Patent number: 7600393
    Abstract: Disclosed herein is a refrigerant distributing device for a multi-type air conditioner, which can discharge an evenly mixed refrigerant to a plurality of indoor units. The refrigerant distributing device comprises an inlet pipe to supply a refrigerant, a distributor, and a plurality of outlet pipes. The distributor comprises an inlet port connected with the inlet pipe, a mix zone having a predetermined space formed therein such that the refrigerant induced through the inlet port forms a vortex flow within the mix zone so as to be evenly mixed, and a plurality of outlet ports separably connected with the mix zone to discharge the refrigerant having passed through the mix zone to an outside. The plurality of outlet pipes selectively connects at least one outlet ports of the distributor and each outlet pipe, for adjusting the amount of refrigerant supplied to each outlet pipe based on the capacity of each indoor unit connected with each outlet pipe.

  • Patent number: 5353066
    Abstract: A method and circuit for preventing the deterioration of picture quality in a video processor is disclosed in which, when an input color video signal is input, a clock signal for a combfilter is locked with a phase-locked loop (PLL) by a burst signal and when a monochrome video signal without the burst signal is input, the clock signal is locked by the output (quasi-burst signal) of a voltage-controlled oscillator of the PLL circuit, before the lapse of one horizontal period, so that the clock signal is constantly locked by a multiple (4 fsc) of the burst signal regardless of the presence or absence of the burst signal of the input video signal. According to a color/mono signal discriminating result, either the burst signal or the quasi-burst signal is selected as a reference signal so that the reference signal is locked to provide a clock signal having a constant phase and frequency, thereby preventing aliasing due to clock variations when the monochrome signal is input and thus improving picture quality.
