Title: Method for preventing from mis-tuning for multi-system tv
Inventor: KIM KI YONG
IPC: H04N5/50
Filed: 1998-11-30
Abstract: PURPOSE: A method for preventing from mis-tuning for multi-system TV is provided so that user's convenience become increased by discriminating the positive and negative of multi-system TV. CONSTITUTION: A method for preventing from mis-tuning for multi-system TV includes a step for discriminating whether the ID of signal is operated when starting the tuning operation(202S,203S). A step is to detect a frequency when operating the ID of the input signal(204S). If the detection of the input frequency is completed, a step is to compare it with the stored channel table value(206S). A step is to discriminate whether the frequency of the input signal is the frequency of the predetermined channel(207S). As the result of the above step, if the frequency of the input signal is not the same as the frequency of the predetermined channel, a step is that the frequency is stored as the negative modulation(209).

Abstract: A resin-impregnated endless belt for a long nip press or calender of the shoe type, or for other papermaking and paper-processing applications, has a base fabric in the form of an endless loop with an inner surface, an outer surface, a machine direction and a cross-machine direction. The base fabric has machine-direction (MD) structural elements and cross-machine-direction (CD) structural elements in an open structure wherein at least some of the MD structural elements and CD structural elements are spaced apart from one another. The MD structural elements cross the CD structural elements at a plurality of crossing points, where they are joined to one another by mechanical, chemical or thermobonding means. A coating of a first polymeric resin is on the inner surface of the base fabric. The first polymeric resin impregnates and renders the base fabric impermeable to liquids, and forms a layer on the inner surface thereof. The coating is smooth and provides the belt with a uniform thickness. A method for manufacturing the belt, using a smooth and polished cylindrical mandrel with a spacer ring slidably disposed thereon, is also shown. <IMAGE>

Title: Self refresh device
Inventor: HAN SANG JIN
IPC: G11C11/403
Filed: 1998-12-30
Abstract: PURPOSE: A self refresh device is provided to reduce power consumption owing to refresh and to realize low power by selectively using a refresh cycle proper for element characteristic. CONSTITUTION: Several signals of drain terminals(pu,pd) in PMOS/NMOS(p-channel/n-channel metal oxide semiconductor) transistors(MP0,MN0) are converted owing to variable resistance depending on fuse blowing. The converted signals are transmitted to gate terminals of each PMOS/NMOS transistor(MP1-MPn,MN1-MNn) to change the amount of electric currents. The amount of currents flowing into inverters(IV1-IVn) is changed by changing the potential of source terminals(pu_a,pd_a) of the inverters. The signals are fed back to the input terminal of an inverter(IV1) from the odd numbers of inverters. At the same time, an oscillation cycle is changed through the variation of delay amount of each inverter owing to the changed currents to form pulse signals having various cycles depending on each different resistance value of variable resistance.
