  • Publication number: 20160337788
    Abstract: Disclosed is a smart bag having a function of notifying a reception of a mobile communication terminal, the smart bag including: a notifying device including a label attached onto one surface of an external side of the smart bag and a backlight combined with one surface of the label; a Bluetooth chip, which is electrically connected with the notifying device and pairs the mobile communication terminal and the notifying device; and a near field communication (NFC) chip, which is attached to one surface of an inner side of the smart bag and activates a Bluetooth function of the mobile communication terminal, in which the Bluetooth chip receives a signal from the mobile communication terminal, so that the backlight is turned on, so that it is possible to confirm a received signal of the mobile communication terminal even outside of the smart bag.

  • Publication number: 20070079058
    Abstract: A mixed serial-parallel content addressable memory (CAM) includes serial CAM cells and parallel CAM cells that are arranged in multiple (N) columns and multiple (M) rows. Each row includes at least one serial CAM cell and at least two parallel CAM cells. The M rows are searched in parallel. For each row, the serial CAM cells are searched sequentially, and the parallel CAM cells are selectively searched in parallel. The CAM further includes a driver that generates search lines for the N columns of CAM cells, one search line per column. The driver sets the search lines to an N-bit value to search for in the CAM. Prior to each search operation, the driver presets at least one search line for at least one column of serial CAM cells to precharge a match line for each row.

  • Publication number: 20060268640
    Abstract: A system and method for sensing a data state stored by a memory cell that includes coupling a first digit line and a second digit line to a precharge voltage and further coupling a memory cell to the first digit line. At least one digit line other than the first and second digit lines is driven to a reference voltage level and the at least one digit line is coupled to the second digit line to establish a reference voltage in the second digit line. A voltage differential is sensed between the first digit line and the second digit line, and a data state based on the voltage differential is latched in response.

  • Patent number: 5980764
    Abstract: A gas injecting gadget or wafer-mounting susceptor, made of a chemical composition comprising 59.8-69.8% by weight of nickel, 25-35% by weight of copper, a valance weight of aluminum, cobalt, manganese, titanium or the combinations thereof, and E trace amount of inevitable impurities, is produced by a method comprising the steps of: a rough cutting process in which the substance is roughly cut and surface-processed; a precise cutting process in which the roughly processed substance is precisely processed in three stages comprising rough process, finishing process and shaping process; a holing process in which a number of fine holes are formed on the precisely processed substance by a drilling process and chips are removed by a reaming process; an abrasion process in which the substance with holes are abraded by a wet abrading process and a belt polishing process; and a washing and inspecting process.

  • Patent number: 5560384
    Abstract: An outdoor sunscreen formed without rope or pole connecting eyelets includes a fabric sheet having a reinforced margin. The reinforced margin is a two-layered structure and lengthwise receives a reinforcing band therein. This margin is formed by folding an edge of the sheet with the reinforcing band lengthwise placed in the folded edge and by fusion welding together inner surfaces of the folded edge through high frequency heating. A plurality of arcuate punched slits are formed on the reinforced margin for providing a rope reception hole. In the fabric sheet, wefts and warps of the reinforced margin are tightly woven such that a woven structure of the margin about each punched slit endures a tensile force applied thereto from a tightened rope.

  • Patent number: 5415915
    Abstract: A corner reinforcement for cloth is disclosed. This reinforcement comprises upper and lower plates for covering the upper and lower surfaces of the corner and reinforcing this corner. These upper and lower plates are integrally formed with each other in a single injection molding and have the same right-angled triangular appearance so as to provide a twofold right-angled triangular structure. This triangular structure of the reinforcement is opened at its hypotenuse but closed at the remaining sides thereof, thereby preventing the corner of cloth from jutting out of the reinforcement after fastening the reinforcement to the corner of cloth. The upper and lower plates each has an opening for a pitching rope and they are integrally formed with annular protrusions or eyelets which are adapted to reinforce the upper and lower plates against pull of the rope tied thereto. The reinforcement further includes grooves and protrusions to clamp the corner of cloth.

  • Patent number: 5327927
    Abstract: A tent for screening the sunlight. The tent comprises a main sheet for screening the downwardly radiating sunlight, a plurality of front and rear tent poles for causing the main sheet to maintain its suspended shape, a plurality of ropes for being stretched to impart a tensile force to the main sheet, a pole support for supporting the tent poles as well as dispersing the vertical force generated in the poles and a detachable side sheet for intercepting the side radiating sunlight. The pole support comprises a base and a pair of pole support pipes which receive lower ends of the pipes. The base is embossed at its under surface with a raised figure to improve the frictional force between said pole support and the ground surface. The pole support pipes concentrate in the center of the base to have a V shape in cooperation with each other.
