Abstract: PURPOSE: A method for fabricating a transistor of a semiconductor device is provided to reduce well junction capacitance by decreasing concentration of a well without changing characteristics of the transistor. CONSTITUTION: In the method, a field oxide layer(1) is formed on an n-type silicon substrate, and a p-well(2) is formed. Next, an oxide insulating layer is formed over a resultant structure and etched to form a contact hole exposing a portion of the p-well(2). Next, a channel stopper ion(5) is implanted into the p-well(2) through the contact hole, and then a gate oxide layer and a polysilicon layer(7) for a gate are sequentially deposited over a resultant structure. Next, the polysilicon layer(7) is planarized by a chemical mechanical polishing process, and then the oxide insulating layer is removed by a dry etching process. Next, a spacer(8) is formed and then an impurity ion(9) with high concentration is implanted to form a source and a drain. Since the channel stopper ion(5) is formed only underneath the gate(7), well junction capacitance is reduce by a decreased concentration of the p-well(2).

Abstract: PURPOSE: A control method of a diesel engine for a vehicle is provided to keep velocity of a vehicle regular with elasticity in driving on an uphill road by raising the velocity. CONSTITUTION: A difference between limit velocity and driving velocity is calculated if a vehicle travels on a downhill road. Arming velocity is set as first set value and arming difference is obtained. If the arming difference is higher than 0, enable velocity is set as second set value. Otherwise, the enable velocity is set as 0. The enable velocity is operated by the difference between limit velocity and driving velocity and then compared with 0 again. If the enable velocity is smaller than 0, offset velocity is set as 0. If the opening of an acceleration pedal is changed higher than fourth set value, the offset velocity is added to the preset limit velocity to obtain new limit velocity. If the driving velocity is lower than the new limit velocity, a control signal for fuel supply is outputted. Otherwise, a control signal for fuel feed stop is outputted. Therefore, the driving velocity of a vehicle is kept regular without regard to uphill or downhill roads.

IPC: D06B7/08
Filed: 1997-09-02
Abstract: Fabric comprising yarns comprising lyocell fibres is treated with a swelling agent, preferably aqueous sodium hydroxide, whilst in a form in which it is unrestrained and free to shrink. The swelling agent causes the lyocell fibres to swell without destroying their structure by dissolution, the amount of swelling being in excess of the amount to which the lyocell fibres will swell during exposure to all subsequent wet processing of the fabric. The effect of the swelling agent is then diluted with water so as substantially to set the yarns in the fabric in the positions relative to one another that they have in the swollen condition. The resulting fabrics are very much less affected by creasing than untreated fabrics are and do not suffer as much from the formation of lines during subsequent wet processing.

Abstract: PURPOSE: An ignition button system of automatic lamp display method is provided to operate an ignition button conveniently without checking character- or picture-used contents of the ignition button by lighting on/off a lamp with the ignition button of a burner immediately when a cooking vessel is laid on a heat plate. CONSTITUTION: A lamp operating circuit is connected, and a lamp(L) of an ignition button is lighted on even though a central pin(c) is contacted with a switch(H) on a gas range by the load of a cooking vessel. After 10sec, the circuit is isolated and the lamp is lighted off. Thereby, the lamp is not mixed with other ignition button lamps by considering time intervals when a user selects another burner. A bottom surface of blades for load sensing is concave while a corresponding upper switch part is convex. The central pin of the blade and the switch keep the same position always so that the switch is not stained by overflowing food. A timer(T) is a unit operated by a pulse signal of the switch. The timer feeds an excitation current to the lamp to light on the lamp. After 10sec, the timer lights off the lamp by isolating the excitation current. Therefore, the user operates the ignition button easily in a dark plate.
