Abstract: PURPOSE: A noise removing device of a vehicle hydraulic type steering servomechanism stabilizes the hydraulic pressure of returning fluid to a rotary valve and prevents the generation of noise in the rotary valve. CONSTITUTION: If a hydraulic pressure is provided to a rotary valve(1) for a steering force increase, a hydraulic pressure controlling valve(2) is simultaneously operated to vary a steering weight according to the speed of a vehicle. If the hydraulic pressure of the rotary valve(1) is flowed into a space(31) of the hydraulic pressure controlling valve(2), the hydraulic pressure of the fluid passing through the small diameter portion of a spool(5) is rapidly altered. Then, the fluid is returned through the porous layer of an oil filter(4) mounted in an expanded portion(34) in stable state when the fluid is returning to the rotary valve(1) through an outflow passage(32). Therefore, the generation of noise in the rotary valve(1) is prevented.

Abstract: PURPOSE: A synchronization method in a base station in an advanced asynchronous radio communication system is provided to synchronize channel cards in a base station with the LC(Long Code) values of a main control block. CONSTITUTION: A main control block judges whether a request signal for the current time is inputted from channel cards(S1). If the current time request signal is inputted, the main control block judges whether the current time is within a transmission possible area(S3). If the current time is within the transmission possible area, the main control block transmits the information of the current time to the channel cards(S5). However, in case that the current time is not within the transmission possible area, the main control block waits until the current time reaches the transmission possible area, without transmitting the current time information(S7). When an LC value is increased(S9), the main control block transmits the current time information to the channel cards(S11).

Abstract: PURPOSE: An additive added to a varistor driven at a low voltage and a low sintering temperature is provided to reduce producing cost by reducing a sintering temperature, perform two functions of a capacitor and a varistor, and drive the varistor at a lower temperature. CONSTITUTION: An additive is added to a varistor which is driven at a low voltage. The additive contains CuO and SiO2 which are mixed in a ratio of 80-90 : 10-20 mol. The additive is added to the varistor, which is a SrTiO3 low voltage driven varistor, as much as 0.05 to 5.5 wt%. Besides Cuo and SiO2, the additive includes one or more of the compositions selected from the group consisting of AO2, BO2 and C2O3. Here, the A is +2 or +4 metal element, the B is +2 or +4 metal element, and the C is +3 metal element. The CuO - SiO2- AO2- BO2 - C2O3 composition is formed in a ratio of 80-90 : 10-20 : 0-5 : 0-10 : 0-5 mol. The additive forms an insulation layer(resistance layer) on the SrTiO3 and thus functions as both a capacitor and a varistor. The sintering temperature is reduced by 100 to 150°C, whereby manufacturing cost is accordingly reduced. The varistor is capable of being driven at a low voltage, and thus it is applicable to small sized and portable electronic products.
