Title: Method of managing addresses of first-in-first-out memory for inter process communication
Inventor: PARK SUN JUN
IPC: G06F12/16
Filed: 1998-12-24
Abstract: PURPOSE: A method of managing addresses of a first-in-first-out(FIFO) memory for an inter process communication(IPC) is provided to detect errors generated while operating the FIFO memory by managing a write address and a read address as cell units, and to detect data errors caused by unstable operations of control signals or clocks while writing/reading the FIFO memory to prevent a system from being unrecoverable, by adding surplus bytes to each cell to detect the errors. CONSTITUTION: A method of managing addresses of a first-in-first-out(FIFO) memory for an inter process communication(IPC) comprises the steps of: allocating a write block address, a write byte address, a read block address, and a read byte address, and initializing the addresses; increasing values of the write byte address one by one, whenever byte data of cells is written in a block of the FIFO memory; counting writing operations of the byte data to confirm whether a cell synchronization signal is received, and writing a corresponding write operation counted value in a surplus byte; and increasing values of the write block address one by one, whenever the byte data is fully written in the block.

Filed: 1998-12-28
Abstract: PURPOSE: An optical pickup actuator is provided to reduce the number of components and wasted electricity by generating driving force using a tracking coil and to miniaturize the optical pickup actuator by lowering the height of a lens holder CONSTITUTION: Flux from a first magnet(18) returns to a third magnet(60), and the flux from the third magnet returns to the first magnet. The straight forward performance of the flux passing through first/second focusing coils(44-1,44-2) is strengthened. Thus, excellent driving force in focusing direction is generated. The flux from a second magnet(19) returns to a fourth magnet(62), and the flux from the fourth magnet returns to the second magnet. Thus, the excellent driving force in a tracking direction is generated by the flux affecting to first/second tracking coils. An optical pickup actuator generates the driving force in the tracking direction from the entire tracking coil. Thereby, the number of tracking coils and wasted current are reduced. The height of the tracking coil is lowered for lowering the height of the lens holder. Therefore, the size of the optical pickup actuator is reduced.

Abstract: PURPOSE: A simultaneous paging method of a multi-exchange is provided to rise the paging success rate by making base stations, which are adjacent to a mobile station and control different exchanges, simultaneously transmit the paging signals when the mobile communication terminal is positioned in a boundary of exchanges. CONSTITUTION: If an incoming call is requested, a gateway station requests a first subscriber location information to a home location register(HLR). The gateway station transmits an incoming call to a first exchange corresponding to the first subscriber location information. When an incoming signal is detected, the first exchange requests a second subscriber location information to the HLR. The first exchange matches the second subscriber location information with a paging list. If the first subscriber location information and an exchange field of the matched paging list have mutually different exchange identifying factors after comparison, a base station controller transmits a corresponding paging message to a first paging message transmitter. The first paging message transmitter identifies an exchange identifying factor of the received paging message, and searches a second paging message transmitter to transmit a paging message by referring to an exchange identifying factor table. The first paging message transmitter transmits the paging message to the second message transmitter. The second paging message transmitter transmits the paging message to a first base station controller corresponding to a base station control station identifying factor included in the transmitted paging message. The first base station controller searches a base station controller from the transmitted paging message, to transmit the paging message to confirmed base stations. The base stations transmit a paging signal to a mobile station set with a specific mobile communication subscriber number through a paging channel.

Abstract: PURPOSE: A constriction clamp for a hose connection is provided to prevent leakage of fluid from a gap and to maintain constrict force while connecting a synthetic resin spiral hose to external surface of a metal nipple. CONSTITUTION: A constriction clamp for a hose connection comprises a metal nipple(P); a synthetic resin hose(H) inserted to an outer face of tip of the metal nipple; a clamp(1) constricting a connect part of the hose; constrict plates(2,3) forming the clamp; insert holes(2b,3b) formed by curving an end portion of the constrict plate; a support bar(4) engaged to the insert hole by a bolt(5); plural engage holes(4a) perforated on the support bar; and reinforcing support pieces(2a,3a) integrally mounted on inner surface of semi-circular constrict plates. The constrict plates and the reinforcing support pieces are engaged for corresponding to the engaged portion of the hose and the nipple. Thereby, a peripheral face spiral protrusion unit(h) is uniformly compressed to entirely attach the inner face of the hose on external circumference of the nipple.
