Abstract: PURPOSE: A method of channel demodulation using voice coding rate calculation method for a CDMA wireless communication system is provided to reduce the processing time of channel demodulation by using the user's voice pattern. CONSTITUTION: In a device of calculating voice coding rate, a channel decoder(210) decodes the channel of received frames corresponding to the coding rate decided by a voice coding rate calculator(218). A channel coder(212) codes the channel of the decoded result(220) from the channel decoder(210). An error calculator(214) calculates error(222) by comparing between the decoded result(220) and the received frame. A decoding process controller(216) compares critical error(226) decided by a processor and the error(222) calculated by the error calculator(214). If the error of the decoded result(220) is smaller than the critical error(226), the decoding process controller(216) orders the channel decoder(210) to stop decoding(224) and sends to the voice coding rate calculator(218) a decoding process information(228) notifying that the received frame comes within the set error range. The voice coding rate calculator(218) calculates the coding rate of the next frame using the coding rate of the first frame.

Abstract: PURPOSE: An outflow unit mechanism is provided to always maintain uniform pressure by controlling two balls installed to an inside regardless of high and low of the fluid pressure. CONSTITUTION: An outflow unit mechanism contains two control holes(1') letting fluid flow out. The upper portion diameter of outflow holes is smaller. As the two control holes are overlapped on a combined location, the diameter of the outflow hole is largely shrunk by enabling an inner expansion body to be expanded. Thus, the operation speed becomes fast. In the opposite case, the two control holes are overlapped to block one outflow hole of an external portion, and the inner expansion body is expanded for a small amount. Thus, the outflow amount is changed into a small amount and the operation speed becomes slow.

Abstract: PURPOSE: A method for fabricating a semiconductor device is provided to prevent the occurrence of a leakage current from a gate electrode to an adjacent conductive layer. CONSTITUTION: In the method, a polysilicon layer(64), a tungsten silicide layer(66) and a nitride layer(68) are sequentially formed on a semiconductor substrate(50) and then anisotropically etched to form a gate electrode(70) by using a mixed gas of sulfur fluoride such as SF6 and chlorine having a higher etch rate to the tungsten silicide layer(66) than the polysilicon layer(64) and the nitride layer(68). Therefore, the tungsten silicide layer(66) is overetched so that a recess(80) is formed on sides thereof. Then, a spacer(72) is formed on sides of the gate electrode(70), allowing a relatively increased thickness thereof on the sides of the tungsten silicide layer(66), and thus preventing the leakage current from the tungsten silicide layer(66) to an adjacent contact formed in a subsequent process.

Abstract: PURPOSE: A voice announcement method of a phone button is provided to make it possible to easily dial by using a phone at nights without illumination and accurately use a phone set with complicate additional functions by announcing a content to proceed or to be inputted by voice. CONSTITUTION: A user hooks off a phone set by picking up the receiver of a transmitting and receiving controller(S110). The user inputs pertinent buttons of a button unit to dial for a specific number of a called party and additional functions and applies it to a main controller(S120). The main controller senses the signal for the inputted buttons, draws out a voice signal recorded in a voice storing/reproducing unit and applies to a voice transmitting unit, so that a voice for the corresponding button is transmitted(S130). The main controller analyzes the content of the signal applied from the button unit and determines whether an additional announcement message is required(S140). If an additional message is required, the main controller applies the corresponding voice signal recorded in the voice storing/reproducing unit to the voice transmitting unit, and outputs the additional announcement message as a voice signal(S150). The main controller performs a corresponding function of the button by the signal inputted from the button unit(S160). As the receiver of the transmitting and receiving controller is hooked on the phone set by the user, the main controller determines whether it is a hook-on state which releases an occupancy of an office line, and if it is not a hook-on state, it is fedback so that input of buttons can be continued, or if it is in the hook-on state, it is terminated(S170).
