Title: Transmission for forward and backward movement
Inventor: KWAK HUI SEONG
IPC: F16H61/38
Filed: 1998-11-25
Abstract: PURPOSE: A transmission for forward and backward movement is provided to maintain traveling performance optimal by keeping the pressure operating to a clutch regular even if the temperature rises due to continuous shifting operations. CONSTITUTION: Hydraulic oil is supplied via a hydraulic pressure input line(3) by the opening of a second orifice part(22). The hydraulic oil supplied to an intermediate hydraulic line(15) and respective clutches(12,13) via a variable orifice(20) increases rather than facing to a main relief valve(4). The leakage amount via inner gaps of respective component is compensated. And the pressure applied to the intermediate hydraulic line and the clutches rises by supplying more hydraulic oil than the leakage. If the pressure of the intermediate hydraulic line and the clutches is restored to normal state, the hydraulic pressure of an accumulator increases. If the pressure of the accumulator rises over a set up value, the increased hydraulic oil is fed to the variable orifice via a hydraulic pressure line(30) of the clutch. Thus, the variable orifice is selected after being converted to a third orifice part(23) from the second orifice part. Thereby, regular operation state is maintained.

Abstract: PURPOSE: A method for diagnosing links between a base station controller and a base transceiver station is provided to exactly decide states of the links, by dividing sections of a link to diagnose the link states in a code division multiple access(CDMA) mobile communication system. CONSTITUTION: A base station controller(BSC) and a call control processor(CCP) check states of links when a link diagnosing command is received in a state of permitting link diagnoses, to examine numbers of available links. If one number of a link is available, a ping-pong test is performed, and if two numbers of links are available, calls using the two links are examined. If the calls do not exist, the CCP and a base transceiver station(BTS) control processor(BCP) block link processes. Link diagnoses are requested to a local code division multiple access(CDMA) interconnection network(LCIN) high-capacity integrated peripheral controller(IPC) control board assembly(HICA) and a BTS interconnection network(BIN) HICA. The LCIN HICA and the BIN HICA perform from a first test to a fourth test to unblock the link processes. The BSC and the CCP transmit tested results to a base station manager(BSM) to display the results to an operator.
