20100178075 | IMAGE FORMING APPARATUS - Disclosed herein is an image forming apparatus including a main body; a developing unit detachably mounted on the main body and having a photoconductive medium; and a cover pivotably mounted on the main body to cover and support an outer end of the developing unit. The cover may comprises a latch engaged with the main body by one end thereof so that the cover supports the developing unit. A member that supports a shaft of the photoconductive medium may also be included. Because the member operates in association with the latch, opening and closing of the cover may be facilitated, accordingly also facilitating separation of the developing unit from the main body. | 07-15-2010 |
20120163882 | FUSING DEVICE AND IMAGE FORMING APPARATUS HAVING THE SAME - A fusing device to reduce lubricant leakage, includes a fusing belt having a heat source placed therein, a pressure roller placed to apply pressure to an outer surface of the fusing belt, and a nip plate to support an inner surface of the fusing belt so as to define a fusing nip between the fusing belt and the pressure roller. The nip plate includes a stepped portion spaced apart from the inner surface of the fusing belt so as to define a space for accommodation of a lubricant applied to the inner surface of the fusing belt. The fusing device may further include a side frame to rotatably support a longitudinal end of the fusing belt. The side frame may be provided with a lubricant guide to guide the lubricant on the longitudinal end of the fusing belt toward the center of the fusing belt. | 06-28-2012 |
20120170957 | FUSING DEVICE AND IMAGE FORMING APPARATUS HAVING THE SAME - A fusing device and an image forming apparatus having the same are provided. The fusing device includes a position regulating device to regulate a position of a side frame which rotatably supports a fusing belt, thereby fixing a position of a fusing nip defined between the fusing belt, inside of which a heat source is placed, and a pressure roller arranged to face the fusing belt. The fusing device prevents shift of a recording medium delivery path due to deformation of the pressure roller. | 07-05-2012 |

20090297944 | LITHIUM SECONDARY BATTERY - This invention relates to a lithium secondary battery, the tab shape of which is improved, thus increasing the safety and improving the electrical properties thereof. The lithium secondary battery includes an electrode group composed of a first electrode, a second electrode, and a separator disposed between the first electrode and the second electrode, a first electrode tab connected to the first electrode, and a second electrode tab connected to the second electrode. The first electrode tab includes a first portion connected to the first electrode and a second portion, which is not the first portion, the width of the first portion being less than the width of the second portion. | 12-03-2009 |
20100233536 | SAFETY APPARATUS USING HIGH POWER BATTERY - Disclosed is a safety apparatus for responding to a battery short-circuit, and more particularly a safety apparatus for use in the event of a short-circuited of a high power battery, in which a PTC function is integrated into a tab of a high power battery. The safety apparatus for responding to a short-circuit of a high power battery comprises a casing, a battery part including a first electrode plate, a separator, and a second electrode plate arranged in that order and disposed inside the casing, a first tab connected to one of four edges of the first electrode plate via a first tab welding part and protruding from the casing, and a second tab connected to one of four edges of the second electrode plate via a second tab welding part and protruding from the casing, wherein a portion of the first tab ruptures when the first tab and the second tab are short-circuited, thus preventing the first electrode plate and the second electrode plate from being short-circuited. | 09-16-2010 |
20110104539 | LITHIUM SECONDARY BATTERY AND MANUFACTURING METHOD FOR SAME - A lithium secondary battery includes: a first electrode having a first current collector, and first active material patterns formed on the first current collector such that the first active material patterns are symmetrically disposed with a first center non-coated portion formed therebetween; a second electrode having a second current collector, and second active material patterns formed on the second current collector such that the second active material patterns are symmetrically disposed with a second center non-coated portion formed therebetween; a first electrode tab connected to the first center non-coated portion; and a second electrode tab connected to the second center non-coated portion. | 05-05-2011 |

20140147712 | SECONDARY BATTERY - Provided is a secondary battery including a battery cell having a cathode tab and an anode tab formed at one side thereof; a pouch formed so as to be enclose and seal the battery cell so that the cathode tab and the anode tab of the battery cell are protruded to the outside; and a shape memory alloy provided in the pouch and having a bent part bent in a specific shape and penetrating through and opening the pouch while being unbent at the time of an increase in a temperature of the battery cell, to discharge gas generated in the pouch when the gas is generated in the pouch due to an increase in a temperature caused by overcharging, overdischarging, and the like, to expand the pouch, thereby making it possible to prevent ignition and explosion. | 05-29-2014 |
20150288022 | SECONDARY BATTERY - The present invention relates to a secondary battery comprising: a battery assembly formed from a positive electrode plate, a separator and a negative electrode plate which are sequentially stacked or wound; a finishing unit for covering the outer surface of the battery assembly in a first direction; and an end tape, the ends of which are fixed to one side and another side of the finishing unit such that the one side of the finishing unit can be elastically drawn in the first direction toward the other side of the finishing unit. | 10-08-2015 |
20150303412 | EMBEDDED FRAME FOR POUCH-TYPE SECONDARY BATTERY AND SECONDARY BATTERY HAVING EMBEDDED FRAME - The present invention relates to an embedded frame for pouch-type secondary batteries and a secondary battery having the embedded frame. The embedded frame is provided in a pouch casing for a secondary battery so as to maintain the external shape of the pouch casing and additionally protect an electrode assembly from an external shock. The embedded frame has a rectangular shape and makes close contact with an inner surface of the pouch casing. The electrode assembly is housed in the embedded frame. A plurality of pores is formed in the embedded frame. | 10-22-2015 |
