Abstract: A vehicular air conditioning system includes a compressor configured to compress a gaseous refrigerant to have a high temperature and a high pressure while an output rotation speed thereof is variably controlled according to a cooling load in a vehicle interior, and a compressor performance deterioration determination part configured to determine whether or not the performance of the compressor has deteriorated according to the magnitude of a difference between an amount of work (W) of the compressor and an amount of power consumption (kW) of the compressor.

Abstract: The method comprises registering at least one of an internet protocol (IP) address and a media access control (MAC) address of the security devices, generating a plurality of public key and private key pairs, encrypting and storing private keys comprised in the plurality of public key and private key pairs using a master key provided from a master key management unit, selecting any one of a plurality of public key and private key pairs when the access of the security device is approved and providing a certificate comprising the selected public key to the security device, receiving a symmetric key encrypted with the public key of the certificate from the security device, and decrypting the private key using the master key provided from the master key management unit.

Abstract: A method of manufacturing a semiconductor device includes: forming a trench in an insulating interlayer by etching the insulating interlayer; forming a conductive layer on bottom, side, and upper surfaces of the insulating interlayer where the trench is formed, using a first deposition process, the conductive layer on the bottom surface of the trench being thicker than the conductive layer on the side surface of the trench; forming a sacrificial layer in the trench covering the conductive layer formed on the bottom surface of the trench using a second deposition process different from the first deposition process; selectively removing the conductive layer formed on the upper surface of the insulating interlayer and formed on the side surface of the trench left exposed through the sacrificial layer; and selectively removing the sacrificial layer, to form a conductive line using the conductive layer remaining on the bottom surface of the trench.

Abstract: The apparatus for transmitting a workpiece along a press line includes a support frame; a support frame driving unit; a plurality of air pipes; an air flow forming unit; a plurality of rollers; and a roller driving unit. The plurality of suction cups are provided at a perimeter of each of the rollers A plurality of air exhaust passages extends from an inner surface of each suction cup to a respective air passage are formed in each of the rollers, such that air within a closed space formed between the suction cup and the workpiece is exhausted to the air passage by a difference between a pressure within the closed space and a pressure in the air passage.

Abstract: There is provided a system for realization of a base station controller in a compact PCI, which establishes a code division multiple access (CDMA) base station controller partly using functions of H.110. The system for realizing a base station controller in a compact PCI uses paths for CDMA packet routines by using partial functions of H.110, extracts clocks from networks without using a GPS and composes a reference clock of the base station controller using the extracted clocks to use the reference clock as a reference frequency in CDMA.

Abstract: A method and apparatus for separating picture image areas in facsimile machines, scanners, and other picture processing equipment, and more particularly to a method and apparatus for separating picture regions by extracting features of graphic image and characters includes a vertical contouring circuit for producing vertical contour data by combining vertical components of an original picture and binary picture data; a horizontal contouring circuit for producing horizontal contour data from horizontal components of the binary picture data; a logic combiner for combining outputs from the vertical and horizontal contouring circuits and a halftone picture; a mode discriminator for selecting between a binary picture and contouring mode; an image area separator for separating image areas with an output from the logic combiner and a halftone picture, and a counter for executing pixel counting from a halftone picture to determine the probability of the presence of a character.
