Abstract: A side view LED package for a backlight unit includes a package body having a cavity with an inclined inner sidewall, first and second lead frames arranged in the package body, the cavity of the package body exposing a portion of at least one of the first and second lead frames placed in a bottom of the cavity to outside, a light emitting diode chip mounted on the bottom of the cavity to be electrically connected to the first and second lead frames, and a transparent encapsulant arranged in the cavity surrounding the light emitting diode chip. The cavity has a depth larger than a mounting height of the light emitting diode chip and not exceeding six times of the mounting height. The height of the sidewall is shortened to improve beam angle characteristics of emission light, increase light quantity, and prevent a molding defect of the sidewall.

Abstract: A side view LED includes an insulating substrate, and first and second metal layers each having first and second areas spaced apart from each other at a predetermined gap and disposed on top and underside surfaces of the insulating substrate, respectively. First and second electrical connectors are formed in a thickness direction of the insulating substrate, connecting the first area of the first metal layer to that of the second metal layer, and the second area of the first metal layer to that of the second metal layer. An LED chip is mounted on the first metal layer and electrically connected to the first and second areas. Also, a wall part is attached to the first metal layer to form an opened area around the LED chip. A protective device is mounted on an underside surface of the second metal layer and electrically connected to the first and second areas.

Abstract: A method for recycling copper oxide includes: a first step in which a sodium hydroxide aqueous solution is added to acidic copper chloride waste etchant produced in the PCB industry, to obtain copper hydroxide slurry; and a second step in which the slurry obtained in the first step is heated and sintered to thereby prepare a needle-form copper oxide. Since copper oxide has a purity of more than 99.0 wt % and the needle-form crystal morphology, so that it has an excellent filtering ability and homogeneous particle size distribution.

Abstract: A battery case for enclosing and hermetically sealing a battery body which generates current. The case includes a first polyethylene terephthalate layer, which is an innermost layer with respect to a battery body, which is adhered to another part of the same layer when sealing the battery body, a polymer layer on the first polyethylene terephthalate layer, a second polyethylene terephthalate layer on the polymer layer, and a polypropylene layer, which is an outermost layer with respect to the battery body, on the second polyethylene terephthalate layer. Therefore, short circuits generated during adhesion between edges of upper and lower portions of the case can be prevented, improving the case sealing process. Also, the deterioration of battery performance, due to a micro short circuit occurring during the sealing of the case, can be avoided. Further, the case sealing process can be safely performed, irrespective of conditions of thermal fusion such as temperature, pressure, and time.

Abstract: An improved method for effectively transmitting a PSMM in a communication system is provided. According to the present invention, a mobile station decides whether s message generated in itself is a PSMM. If the message is the PSMM, the mobile station decides whether the PSMM is the most recent PSMM. If the PSMM is not the most recent PSMM, the mobile station waits until the most recent PSMM is generated. If the PSMM is the most recent PSMM, the mobile station transmits only the most recent PSMM to the base station in order to gain an acknowledgment from the base station.
