摘要:
A method for manufacturing a multilayer ceramic capacitor, in which internal electrodes printed on each of a plurality of dielectric sheets have reduced thicknesses using an absorption member, thereby allowing the multilayer ceramic capacitor to have a high capacity and be minimized. The method includes printing the internal electrodes on each of the dielectric sheets, and stacking the dielectric sheets, wherein the internal electrodes formed on each of the dielectric sheets have a reduced thickness by causing an absorptive member to contact the surface of each of the dielectric sheets provided with the internal electrodes and then separating the absorptive member from the surface so that portions of the internal electrodes having a designated thickness are eliminated, and the dielectric sheets provided with the internal electrodes having the reduced thickness are stacked to form a chip element.

Disclosed is a semiconductor package and a method for manufacturing the same. A planar or substantially planar die pad is disposed within a leadframe and is connected to the leadframe by a plurality of tie bars. An perimeter of an upper and lower surface of the die pad is half-etched to increase the moisture-permeation path of the finished package. A plurality of rectangular leads extends from the leadframe toward the die pad without contacting the die pad. A silver-plating layer may be formed on the upper surface of the leadframe. A semiconductor chip is mounted on the upper surface of the die pad in the leadframe. After deflashing, the package is treated with a sulfuric (H2SO4)-based solution to restore the internal leads to their original color. Prior to singulation, the externally exposed bottom surfaces of the leads are plated with copper, gold, solder, tin, nickel, palladium, or an alloy thereof to form a predetermined thickness of a plating layer. The singulation step comprises forming a burr at a peripheral side surface of the leads in the upward direction. The finished package may be marked with a recognition mark to enable a user to more easily identify the first lead.

Provided is an air blower for an air conditioner. The air blower for the air conditioner includes a centrifugal fan and a fan housing. The fan housing covers the centrifugal fan, and forms a scroll-type flow path having a varying cross-sectional area and guiding air forcibly blown by the centrifugal fan to an outlet. Here, a bottom surface of the scroll-type flow path inclines and is thinnest near a region where the scroll-type flow path ends. The thickness of the bottom surface progressively increases along a straight line running from a region where the bottom surface is thinnest to an opposite outer side of the scroll-type flow path through a center of the centrifugal fan.

The present invention relates to an insert for slot milling, and more specifically, to an insert for slot milling which can smoothly form a front end surface of a concave portion of a slot formed at a cutting target, and provides a safe use thereof by preventing the erroneous installation of cutting inserts coupled with insert-installation seats on both sides of a milling cutter body to prevent damage of the cutting inserts and the milling cutter. To this end, the present invention is characterized in that the plurality of cutting inserts are provided around the slot milling cutter body, one of two cutting inserts protrudes with respect to one side of the milling cutter body and the other protrudes with respect to the opposite side of the milling cutter body, and two cutting inserts are formed with different structures to prevent the erroneous installation thereof on the insert-installation seats prepared on both sides of the milling cutter body.

A remote controller (100) and a system and method for remotely controlling a digital TV are disclosed. A memory card (110) is mounted in the remote controller (100), and the remote controller (100) receives video or audio data inputted from the memory card (110) and transmits the received data to a TV body (300). The remote controller (100) receives the video or audio data from the memory card (110) modulates the received data into a wireless signal and transmits the modulated wireless signal, and the TV body (300) receives the wireless signal transmitted from the remote controller (100), demodulates the received wireless signal into the video or audio data and reproduces the demodulated video or audio data. Therefore, the user can remotely control the TV body (300) without personally inserting the memory card (110) into the TV body (300). As a result, the user does not need to move to a place where the TV body (300) is located resulting in convenience in use.

Disclosed herein is a composition for the treatment bone fracture comprising N-hydroxy-4-{5-[4-( 5-isopropyl-2-methyl-1,3-thiazol-4-yl)phenoxy]pentoxyl-benzamidine, 4-{5-[4-(5-isopropyl-2-methyl-1,3-thiazol-4-yl) phenoxy]pentoxy}-benzamidine or pharmaceutically acceptable salts thereof as a medicinally effective ingredient. The composition of the present invention can significantly reduce the volume of bony callus, and increase bony density and strength of bony callus, and decrease the contents of connective tissue and cartilage tissue in bony callus, and thus promote loss and ossification of the bony callus formed during the fracture healing process. Therefore, the composition of the present invention is useful for the treatment of bone fracture.

Disclosed is a method of manufacturing a printed circuit board for fine circuit formation, in which an unnecessary metal layer formed on the upper portion of a circuit pattern is removed through mechanical polishing and then chemical etching. In place of expensive chemical mechanical polishing, in the method of the invention, mechanical polishing and chemical etching are continuously applied to thus sequentially remove and planarize the unnecessary metal layer. Thereby, through an inexpensive, simple, and continuous process, the planarization procedure can be precisely performed, thus making it possible to apply the method to large areas and economically realize a fine circuit pattern.
