Abstract:
Provided are a heat sink and a memory module using the heat sink. In one embodiment, the heat sink includes a first and second guide pin respectively disposed in first and second heat spreaders placed around an object to be cooled. The first and second guide pins help prevent misalignment problems from occurring between the first and second heat spreaders, as well, as helping prevent the first and second heat spreaders from contacting each other when the first and second heat spreaders are pressed by pressure applied from the outside.
Abstract:
An antenna device for a mobile terminal. The antenna device includes a first antenna pattern provided within a case of the mobile terminal, and a second antenna pattern provided within the case and electrically connected to the first antenna pattern through contact with the first antenna pattern. Therefore, by forming an antenna device with an antenna pattern for use in a low frequency band, the antenna device may be conveniently used and decrease the size of the mobile terminal.
Abstract:
An short message service switching private branch exchange system and a method can reduce costs. The method can include certifying whether a usable DSP exists or not when an office line and a speech path are connected to each other, and transmitting an short message service signal transmitted from the office line to the DSP through a PCM channel if the usable DSP exists. A main processor of the private branch exchange can certify an extension line terminal that will receive short message service, generate an short message service signal having a format corresponding to a kind of the extension line terminal by using the DSP, and transmit the formatted SMS signal to an extension line interface unit of a corresponding extension line terminal. The system switches an SMS signal between an office line and an extension line by sharing the DSP, for example, by time division.
Abstract:
The present invention relates to a process for effectively preparing prostaglanin derivatives and to a stereospecific alkyl halide containing 15S-alcohol group as a starting material.
Abstract:
A system and method for displaying font in a wireless telephone. The system and method employ the operations of converting base font data into converted font data, wherein the converted font data has a data bits equal in number to data bits of a background screen into which the converted font data will be transcribed; generating a mask for the converted font data; storing the converted font data and the mask in a memory of the wireless telephone; retrieving the mask stored in the memory. The system and method further employ the operations of executing an AND operation to logically AND the retrieved mask and the background screen to generate; a background screen base; retrieving the converted font data stored in the memory; executing an AND operation to logically AND the retrieved font data and a color data, thereby coloring the converted font data which are white data; and executing an OR operation to logically OR the background screen base and the colored converted font data in order to display a character on the background screen.
Abstract:
The present invention relates to a novel process for preparing sulfamoyl-substituted phenethylamine derivatives, specifically, 5-{2-[2-(2-alkoxy-phenoxy)ethylamino]-propyl}-2-methoxy-benzene sulfonamide of the formula (1).
Abstract:
A test coupon for measuring a dielectric constant of a memory module substrate has a plurality of test pattern layers each having a long trace and a short trace formed thereon. A first test pattern layer has an exposed surface and a second test pattern layer is formed internally. The first test pattern layer has probe pads respectively connected to the long and short traces of the first and second pattern layers. Probe pads of the first test pattern layer are connected to a via contact of the second test pattern layer by via holes. The via contact of the second pattern layer is connected to the long and short traces of the second pattern layer. The test coupon is used to measure the dielectric constant of a module board.
Abstract:

More particularly, it relates to a synthetic method of oxazoline derivative having the structure of formula I. ##STR1## wherein R represents phenyl, benzyl, methyl, ethyl, isopropyl, isobutyl, cyclohexyl or cyclohexylmethyl.
Abstract:
A medicinal liquid pushing apparatus according to an embodiment of the present disclosure has a medicinal liquid channel that guides a flow of a medicinal liquid. The medicinal liquid pushing apparatus includes: a reservoir defining an internal space configured to store a medicinal liquid on the medicinal liquid channel; a reservoir pushing member configured to press the reservoir downward; a button member disposed to be spaced apart upward from the reservoir pushing member and configured to be movable downward; and a pressing member disposed between the button member and the reservoir pushing member and configured such that a lower end of the pressing member presses the reservoir pushing member downward while the pressing member is compressively and elastically deformed in an upper-lower direction when an upper end of the pressing member is pushed downward by the button member.
Abstract:
A medicinal liquid injection apparatus according to an embodiment of the present disclosure includes: a medicinal liquid storage part configured to form an internal space for storing a medicinal liquid and a priming storage space extending from the internal space and having one end located at a connection point between the priming storage space and the internal space; and a medicinal liquid flow part configured to be capable of being coupled to the medicinal liquid storage part, the medicinal liquid flow part having a guide flow path for the medicinal liquid that is configured to be capable of being connected to the other end of the priming storage space in a state that the medicinal liquid flow part is coupled to the medicinal liquid storage part.
