Abstract:
Disclosed are a multilayer ceramic condenser and a method of manufacturing the same. The method includes printing a plurality of stripe-type inner electrode patterns in parallel on ceramic green sheets; forming a laminate by staking the ceramic green sheets having the plurality of stripe-type inner electrode patterns printed thereon; cutting the laminate in order to have a structure in which first and second inner electrode patterns are alternately stacked; and forming a first side part and a second side part by applying ceramic slurry in order to cover the sides of the laminate to which the first and second inner electrode patterns are exposed.
Abstract:
A termination circuit is connected to an input buffer receiving a data signal, and includes at least one termination resistor connected to the input buffer for impedance matching. At least one switch controls a connection between the input buffer and a corresponding one of the at least one termination resistors. A control signal generator generates a control signal for selectively enabling the termination circuit by controlling each of the at least one switches. The control signal has an input period less than or equal to an input period of a data signal.

Abstract:
The present invention relates to a blend of polyolefin comprising a modified chlorinated polypropylene. This invention provides a blend of polyolefin comprising a novel amine modified chlorinated polypropylene capable of improving printability by promoting adhesion with ink when the ink is printed or coated on plastic products including film and sheet. The present invention provides a novel blend of polyolefin comprising a modified chlorinated polypropylene, which is prepared by substituting 1-99.9 mole % of chlorine of a chlorinated polypropylene, whose chlorine content is 1-75 wt % and whose number average molecular weight is 100-400,000, with ammonia or an amine compound and is capable of improving dyeability and adhesion performance. This invention also provides the modified chlorinated polypropylene and a method for preparing the same.

Abstract:
A locking apparatus for locking a magazine configured to receive a printed circuit board (PCB) may include an actuator, a rotating block, and a locking member. The actuator may be installed on the magazine. The rotating block may be connected to the actuator. The rotating block may be rotated about a vertical axis. The locking member may be rotatably connected to the magazine about the vertical axis. The locking member may be selectively combined with the rotating block to block a front face of the magazine, thereby preventing breakaway of the PCB from the magazine.
Abstract:
A stacked semiconductor package is presented which includes multiple semiconductor chips and through-electrodes. Each semiconductor chip has bonding pads formed on a first surface of the semiconductor chip and has a projection which projects from a portion of a second surface of the semiconductor chip. The first and second surfaces of the semiconductor chip face away from each other the first surface. The through-electrodes pass through the first surface and through the projection on the second surface.
