Abstract: PURPOSE: A method for manufacturing a static random access memory(SRAM) device for guaranteeing contact hole margin is provided to reduce the size of the device and to improve integration, by sufficiently guaranteeing the contact hole margin. CONSTITUTION: A polysilicon layer for a gate of a drive transistor is deposited on a semiconductor substrate(41) having a field oxide layer(42) by a well-known deposition method. A predetermined portion of the polysilicon layer is patterned to form a gate electrode(43) of the drive transistor. A polysilicon layer for a spacer(44) is deposited on the semiconductor substrate to cover the gate electrode, and a predetermined portion of the polysilicon layer for the spacer is etched to form the spacer on the side surface of the gate electrode of the drive transistor. Impurity ions are implanted into the exposed semiconductor substrate to form a source/drain region. An oxide layer for a buffer, a polysilicon layer for a barrier and an interlayer dielectric(47) are sequentially stacked on the resultant structure. A predetermined portion of the interlayer dielectric is etched to expose the drain region by using the polysilicon layer for the barrier and to form a contact hole. The polysilicon layer for the barrier and the oxide layer for the buffer which are left in the contact hole, are eliminated. A node line(48) which contacts the gate electrode and the drain region simultaneously, is formed.

Abstract: PURPOSE: A method for refrigeration control of portable electronic equipment is provided to change the refrigeration capability by following the calorific volume and to supply an equipment that is appropriate for the method. CONSTITUTION: A method for refrigeration control of portable electronic equipment is composed of differentiation, detection, ventilation. Control circuit distinguishes every mode selection when note personal computer(10) is turned on(S1). If performance mode has been selected, whether a plug(16) is connected to the jack(17) of PC's main body(11) is determined(S2). At this time, power is supplied to PC's main body through the plug, therefore user can use note personal computer without worrying about PC's main body's electric consumption. Control circuit(40) sets frequency of clock signal, which is created by clock generation circuit(43), as 1st frequency(S4), it operates ventilation fan(26), and as a result CPU's(18) heat is ventilated through radiation plate(23) and pin(24). If it is confirmed that plug is disconnected in S2, clock signals frequency generated in clock generation circuit as 2nd frequency, power is supplied to CPU only from the battery(21), not from the plug, power supply mode is changed to low frequency mode, therefore extending battery's operation time. Control circuit receives temperature in CPU's vicinity through temperature sensor(42) and compares detected temperature of temperature sensor to standard temperature(S6). If detected temperature is less than standard temperature, control circuit continues to disable ventilation fan(S8). When temperature arises to standard temperature, control circuit returns to S4 and operates ventilation fan. If silence mode is detected from S1, control circuit selects newly generated signal of clock generation circuit as 2nd frequency in S8 and control circuit orders ventilation to stop its operation in S7.

Abstract: PURPOSE: A turbocharger protecting device is provided to prevent damage on a turbocharger by supplying oil from an oil tank installed in addition to an oil feeder in the cold start of an engine or sudden acceleration. CONSTITUTION: A turbocharger protecting device comprises an oil tank(7) supplying oil to an oil feeder(6), a glow plug(8) inserted in the oil tank and radiated by an ECU(Electronic Control Unit), and a non-return valve(9) supplying oil to bearings(5) supporting a rotating shaft(2) by being opened when pressure of the oil tank rises over a specific level. As oil is not supplied to the rotating shaft and the bearing in cold start or sudden acceleration, temperature of the rotating shaft rises over a specific level and the ECU supplies power to the glow plug to heat oil in the oil tank. The oil is gasified and internal pressure of the oil tank rises. Internal pressure of the oil tank over a specific level is applied to elastic valve bodies(91,92) in the non-return valve. The elastic valve bodies are opened and oil flows to an oil supply path from the oil tank. The oil cools the rotating shaft and the bearing, and smooth lubricating action is performed.

Abstract: A method for the "dry" production of sodium percarbonate (dry process), in which monohydrate crystals of sodium carbonate are reacted with a quasi-stoichiometric quantity of concentrated aqueous hydrogen peroxide solution, relative to the quantity of active oxygen required in the sodium percarbonate to be produced. This method can be combined to great advantage with subsequent compaction of the sodium percarbonate obtained. Sodium percarbonate products containing varying concentrations of active oxygen of at least 10 weight percent, particularly high active oxygen concentrations of above 14.5 weight percent, can be produced. The resulting sodium percarbonate products are distinguished in that they have remarkably advantageous dissolution rates, stabilities and compatibility with detergent bases, and are superior to conventional sodium percarbonates obtained, for example, by a crystallization process. The invention also relates to the sodium percarbonate products obtained and to detergent compositions containing such sodium percarbonate products.

Abstract: PURPOSE: A method for removing an organic molecular film is provided to completely remove the film on a substrate by ultraviolet rays. CONSTITUTION: An organic high-molecular film to be removed on a substrate is exposed to ultraviolet rays of a wavelength of 180 microns or shorter, whereby the film is completely decomposed and can be removed. Moreover, since the ultraviolet rays of the wavelength of 180 microns or shorter are hardly transmitted to a transparent conductive oxide, such as an ITO(indium-tin oxide), the rays can be used for removing a polyimide orientation film having defects, such as a defective printing, on a TFT array board with an ITO transparent electrode pattern formed on the surface of the structure of a TFT. By having the polyimide orientation film on the TFT array board irradiated with the rays of wavelength of 180 microns or shorter, the defect orientation film on the TFT array board can be completely removed, without giving adverse effects to the characteristics of the TFT. After that, the defective orientation film is again sent to an orientation film forming process. Similarly, by having the TFT array board irradiated with the rays of the wavelength of 180 microns or shorter prior to an adhesion of an orientation film to the TFT array board, impurities in the TFT array board can be also removed.
