Abstract:
An image apparatus and a method for receiving a video signal are provided. The image apparatus includes dedicated input terminals for receiving only particular video signals, and a common input terminal for receiving diverse video signals, and determines the format of video signals input through a corresponding input terminal and then displays the determined format on a screen. Accordingly, the number of input terminals can be reduced and the user can identify the format of the video signal input through the common input terminal

Abstract:
Provided are a semiconductor memory device and a magneto-logic circuit which change the direction of a magnetically induced current according to a logical combination of logic states of a plurality of input values. The semiconductor memory device comprises a current driving circuit, a magnetic induction layer, and a resistance-variable element. The current driving circuit receives a plurality of input values and changes the direction of a magnetically induced current according to a logical combination of logic states of the input values. The magnetic induction layer induces magnetism having a direction varying according to the direction of the magnetically induced current. The resistance-variable element has a resistance varying according to the direction of the magnetism induced by the magnetic induction layer.
Abstract:
A multi-stage rotary compressor comprises: a casing having a sealed space therein; a driving unit installed in the casing, for generating a driving force; a first compression unit and a second compression unit for receiving the driving force from the driving unit and compressing a refrigerant; and a connection unit for connecting the first and second compression units and guiding the refrigerant discharged from the second compression unit to be sucked directly in the first compression unit and then re-compressed, by which it is possible to vary capacity, even using every plurality of compression units, and to obtain power saving effect suitable for a saving mode.
Abstract:
A fusing unit is formed along a printing path in an image forming apparatus and fuses an image transferred to a printing medium. The fusing unit includes: a heat source; a nip plate which is heated by the heat source, and comprises a nip part to heat and press the printing medium; and a reflection member to reflect heat generated by the heat source toward the nip part. A belt member is rotatably provided about the heat source, the nip plate and the reflection member, and guides the movement of the printing medium. A driving roller faces the nip part and rotatably drives the belt member. The nip plate and the driving roller form a fusing nip, which quickly heats and provides for quick fusing of a toner image to a printing medium.
