Title: Controller oscillator system and method
Inventor: HALAMIK JOSEF
IPC: H03K4/06
Filed: 2000-12-06
Abstract: PURPOSE: A controller oscillator system and method is provided to reduce systems costs and being suited for manufacture in integrated circuit and to simplify the structure of an oscillation system. CONSTITUTION: In operation, with the output of comparator(82) being in a low logic level state, the output of inverter(102) will be in a high logic level state. Thus, transistor(104) is turned on and sinks the current from current source(110) while keeping transistor(106) turned off. While transistor(106) is turned off transistor(108 )will also be turned off which allows capacitor(114) to be charged by current source(112). Hence, capacitor(114) continues to charge as long as the output from comparator(82) remains low. When capacitor(114) charges to a voltage equal to Vhigh, the output of comparator(82) switches from the low logic level state to a high logic state. Transistor(104) is then turned off and transistors(106) and(108) turn on. Transistor(108) then sinks current and discharges capacitor(114). Capacitor(114) will continue to discharge until the voltage thereacross reaches Vlow at which the output of comparator(82) goes low and charging begins again. The charging and discharging of capacitor(114) produces the saw tooth signal at input(84) of controller oscillator(80). And varying the rate of the charging and discharging of capacitor(114) can change the shape of the saw tooth signal produced by generator(100) and thus the shape of the output pulse from controller oscillator(80). The charge and discharge rates can be varied by varying the ratio of the currents supplied from current sources(110) and(112) as well as the ratio of sizes of transistors(106) and(108) as is known.

Patent KR-20010024341-A (KR)
IPC: H03H17/02
Filed: 1998-10-15
Abstract: Several audio signal processing techniques may be used in various combinations to improve the quality of audio represented by an information stream formed by splice editing two or more other information streams. The techniques are particularly useful in applications that bundle audio information with video information. In one technique, gain-control words conveyed with the audio information stream are used to interpolate playback sound levels across a splice. In another technique, special filterbanks or forms of TDAC transforms are used to suppress aliasing artifacts on either side of a splice. In yet another technique, special filterbanks or crossfade window functions are used to optimize the attenuation of spectral splatter created at a splice. In a further technique, audio sample rates are converted according to frame lengths and rates to allow audio information to be bundled with, for example, video information. In yet a further technique, audio blocks are dynamically aligned so that proper synchronization can be maintained across a splice. An example for 48 kHz audio with NTSC video is discussed.

Abstract: PURPOSE: To prevent rise of a resistance value after aging test by preventing void from remaining in a connection material when an electronic element such as a bare IC chip is mounted on a wiring circuit substrate by a liquid or paste- like connecting material. CONSTITUTION: The surface tension (25deg.C) of a connection material comprising thermosetting resin is adjusted to 25 to 40 mN/m by compounding silicone resin surfactant or fluorine resin surfactant.
