Disclosed is a cover system for a portable communication device which is latched or separated according to pulling or pushing a cover unit so as to open/close a slot entrance of a portable communication device. The cover opening/closing apparatus includes a slot entrance formed on a body of the portable communication device; a cover unit for opening/closing the slot entrance, the cover unit being assembled with the slot entrance and latched to or separated from the slot entrance according to pulling or pushing the cover unit; a plurality of assembly units formed on the slot entrance; and a plurality of latching units formed on the cover unit, assembled to be inserted into and withdrawn from the assembly units, and latched to or separated from the assembly units according to pulling and pushing or lifting the cover unit.

An embodiment is a circuit including 2n−1 first comparators to generate a first result by comparing data from at least two of 2n memory cells to which test pattern data are written. 2n−1 first switching circuits provide the first result or a disable signal responsive to a first switching signal. And 2n−2 second comparators generate a second result by comparing signals output from some of the 2n−1 first switching circuits. N may be a natural number greater than or equal to three.

The present invention relates to a method of preparing a vinyl chloride polymer, and more precisely, a method of preparing a vinyl chloride polymer having excellent processability by raising a final polymerization temperature up to 5˜20° C. from an first polymerization temperature.
摘要:
The present invention provides a method of preparing vinyl chloride polymer having excellent processability and high bulk density by the separate stepwise additions of vinyl chloride monomer during suspension polymerization.

An ink-supply device comprises: a body in which at least one housing space is formed and which is for housing at least one ink pack in the respective housing spaces; ink discharge tubes which are coupled to ink outlets of the respective ink packs; ink-supply tubes which are coupled to a cartridge; and a coupling members which are coupled between the ink-supply tubes and the ink discharge tubes linked to ink packs of the same color. A multiple loading type of ink-supply device is positioned below the cartridge such that excessive ink pressure does not occur in the cartridge and there is therefore the advantage that damage to the cartridge head can be prevented even without providing a separate damper.

A portable electronic apparatus functioning as a pen-table, includes a touch-screen module for detecting contact with an external object and creating position data of a detected region. The portable electronic apparatus, by functioning as a pen-table, eliminates the need to install or carry a mouse, a pen-table, etc. for controlling a personal computer, a laptop computer or the like. A local area communication module transmits and receives data based on a local area communication protocol, and a display module displays the detected region and information on a user interface (UI) and functions of the apparatus. A controller controls the operations of the modules in response to the user's input so as to transmit position data created by the touch-screen module to an electronic device that includes the functions of a pen-table and local area communication.
