Title: Hydraulic control system for automatic transmission with six gears for vehicle
Inventor: KANG HYEON GU
IPC: F16H61/06
Filed: 2002-09-30
Abstract: PURPOSE: A hydraulic control system of a six-speed automatic transmission is provided to reduce the production cost by controlling and distributing hydraulic pressure through four duty control solenoid valves and two on/off solenoid valves. CONSTITUTION: A manual valve(22) changes oil passages by interlocking with a select lever(12). First, second, third and fourth pressure control valves(14,16,18,20) control D-range pressure from the manual valve by controlling through the control pressure of first, second, third and fourth solenoid valves(S1,S2,S3,S4). The solenoid valves are controlled by the decompression from a reducing valve. A first direction switching valve(24) supplies the hydraulic pressure from the second pressure control valve to two ports selectively by controlling through a fifth solenoid valve(S5). A second direction switching valve(26) connects the first direction switching valve and a line pipe with one port selectively by controlling through a sixth solenoid valve(S6). A switch valve(28) supplies the hydraulic pressure from the second direction switching valve to a second clutch(C2) and first and second fail safe valves(32,34) selectively by controlling through two control pressures from the manual valve. A N-R control valve(30) supplies the hydraulic pressure from the manual valve at a rear range to a first brake by controlling through the second solenoid valve. The first fail safe valve supplies the hydraulic pressure from the switch valve to the first brake by controlling the partial hydraulic pressure from the second clutch, a second brake and the manual valve. The second fail safe valve supplies the hydraulic pressure from the third pressure control valve to the second brake by controlling through the partial hydraulic pressure from the first, second and third clutches and the hydraulic pressure from the manual valve. A third fail safe valve(36) supplies the hydraulic pressure from the first direction switching valve to a fourth clutch by controlling through the partial hydraulic pressure from a third brake and the hydraulic pressure from the manual valve. Thereby, one solenoid valve for duty is alternated to two solenoid valves for on/off.

Title: Method for adjusting focus bias in an optical-disc playback system
Inventor: LEE JONG UK
IPC: G11B7/095
Filed: 2002-12-30
Abstract: PURPOSE: A method for controlling a focus bias of an optical disk reproduction system is provided to calculate a PLL(Phase Locked Loop) jitter value by using a falling edge or a rising edge of an FG(Frequency Generator) signal, thereby exactly determining an optimal focus bias even though a PLL jitter signal vibrates in sine wave type. CONSTITUTION: A reproduction system rotates an optical disk by rotating a rotative motor(S51), and adjusts a focus to the disk by driving a focus actuator of a pickup(S53). The system generates an FG signal(S55), and applies focus biases(S57). The system generates an RF signal when the focus biases are applied, and generates a PLL jitter signal(S58). If the FG signal becomes a falling edge or a rising edge, the system calculates PLL jitter values for the PLL jitter signal(S61,S63). The system decides whether a next set focus bias exists(S65). If not, the system selects one PLL jitter value by extracting the plural PLL jitter values(S67). The system retrieves a focus bias that causes the selected PLL jitter value from the plural focus biases, and determines the focus bias as an optimal value(S69).
