Title: An apparatus for cleaning the capillary viscometer
Inventor: HWANG UI CHANG
IPC: B08B3/00
Filed: 2002-12-06
Abstract: PURPOSE: A capillary viscometer cleaner is provided to clean various kinds of viscometers by adjusting an interval of an inlet and an outlet in the viscometer. CONSTITUTION: A main body case has a certain internal space. A solvent tank(10) stores by arranging in the internal space and filling a certain amount of solvent. A solvent heater(15) vaporizes the solvent by offering heat source inside the solvent tank. A distribution pipe(20) has at least one inlet adaptors(21) to be connected with a viscometer. Solvent steam inside the solvent tank is flowed into the distribution pipe through a vacuum discharge line. A cooler(30) has at least one outlet adaptors to be connected with the discharged portion of the solvent steam. The cooler condenses the solvent steam. A return tank(40) stores the condensed solvent temporarily and connected with the solvent tank through solvent return lines(14,42). An air heater(50) heats air of an air supply line to dry the cleaned viscometer by supplying hot air into the distribution pipe. A controller controls the operating time of the solvent heater and the air heater and controls the opening/closing time of valve members(54) in the vacuum supply line, the solvent return lines and the air supply line. Thereby, the cleaning efficiency is increased and the washing cost is reduced.

Title: Method for performing radio resource level registration in a wireless communication system
IPC: H04W60/00
Filed: 2001-01-09
Abstract: Techniques to reduce the amount of registration required by a mobile station in a wireless communication system, especially if the registration zones are defined to be small areas. In one scheme, a mobile station registers (e.g., at R-level) with a network entity (e.g., a base station) each time it enters a new registration zone, which can correspond to an R-TMSI zone defined by GSM MC-MAP. The mobile station maintains a timer for each zone with which it has already registered but has since left. If the mobile station leaves a particular zone for a period longer than a time-out period, the registration with that zone times out, and the mobile station re-registers with that zone whenever it re-enters the zone. The mobile station may implement zone-based, timer-based, implicit, traffic channel RR, and some other registrations, or a combination thereof. Parameters to facilitate registration may be defined by a base station.

Abstract: PURPOSE: A method and an apparatus for loading the data of a liquid crystal display are provided to minimize the number of the signal lines and the number of pins between the timing controller and the ROM and to reduce the size of the ROM. CONSTITUTION: A method and an apparatus for loading the data of a liquid crystal display includes a first memory and a second memory. The first memory stores the modulation data and outputs the modulation data in response to the serial address assign signal. And, the second memory performs the load of the modulation data by generating the serial address assign signal.
