IPC: H01L21/336
Filed: 1999-05-10
Abstract: PROBLEM TO BE SOLVED: To provide a thin film transistor which has its performance and reliability improved, and its manufacture. SOLUTION: To form a coplanar thin film transistor having an active layer of polycrystalline silicon, a polysilicon film 3 is formed on an undercoat film 2 having a recessed part 12 formed in a desirable shape by patterning. The top surface of the polysilicon film 3 is polished by a chemical mechanical polishing method(CMP) to remove projections of polysilicon grain boundary parts, thereby forming a flat surface in level with the top surface of the undercoat film. Then a gate insulating film 4, a gate electrode 5, an inter-layer insulating film 6, and source and drain electrodes 7 and 8 are formed on the polished polysilicon film and undercoat film.

Title: Tungsten halogen lamp and manufacture of it
Inventor: HATAKEYAMA ATSUSHI
IPC: H01K1/50
Filed: 1990-05-21
Abstract: PURPOSE:To readily obtain a tungsten halogen lamp of stable performance and high reliability by precooling the bottom of a bulb and cooling it again upto the upside so that filler gas can be securely filled into the bulb. CONSTITUTION:After the inside of a glass bulb 1 that is linked to an exhausting device via an exhaust tube 3 is exhausted to be vacuum, a predetermined amount of halogenated gas such as bromine and mixed gas of inert gas like xenon and nitrogen is introduced into the bulb 1. After a head-bulb is closed, a cooling box 4 is positioned, as indicated by a full line, with the liquid level of liquid nitrogen 5 reaching at about 10mm from a sealing unit of the glass bulb 1 to precool the bottom of the bulb 1. Then, after the bulb 1 is cooled again upto the upside in the liquid nitrogen 5, the cooling box 4 is moved downward to seal the exhaust tube 3 at the predetermined position for sealing using an oxyhydrogen burner. Thus, since the majority of the filler gas is solidified at the bottom of the bulb through precooling, the exhaust tube can not be sealed by liquefaction occuring through main cooling, and the filler gas at predetermined pressure can be filled with high accuracy.

Abstract: PURPOSE:To form uniformly the shape of a winding hole by packing a winding slot whose surface is formed with a metallic magnetic film by a glass material, removing part of the glass material, and forming a glass fluidity restriction film to the surface of the remaining glass material. CONSTITUTION:A couple of core blocks 12a, 12b are butted to each other while metallic magnetic films 6 are opposed to each other, a bonding glass 13 is inserted to a glass arranging slot 10, the glass is heated or cooled gradually under inactive gas atmosphere such as N2, Ar while the side face is pressed, the glasses 7, 13 are molten to bond a couple of the core blocks 12a, 12b incorporatedly. Since the glass fluidity restriction film 9 is formed adhesively to the surface of the glass 7 imbedded in the winding slot 2, even when the viscosity of the glass 7 goes to <=10<-4> poise at the time of welding, the movement quantity of the glass 7 is decreased. Thus, the shape of the wind slot 2 is formed uniformly.

Abstract: PURPOSE: To produce high grade briquette by following method in which reducing material and residual oil generated during distilling crude oil as a binder, are arranged into iron ore-powder, thereafter the powder is formed under pressure into a predetermined shape after mixing and kneading said powder at a high specially determined temp.  
     CONSTITUTION: 8W20wt% Carbone material as a reducing agent is added into iron ore-powder crushed in a moderate particle size, and it is charged in a mixing and kneading device. Then residual oil (DR) being generated during distilling crude oil and having weight of 3W10% to the iron ore-powder is added into said powder as a binder, and is mixed and kneaded. In this case, the powder is mixed  and kneaded at 100W150°C higher than the softening temp. of DR. DR can be sufficiently penetrated between each particle and the surfaces of the particles are substantially coverted with DR. Thus the mixture heated and kneaded is sent to a  forming machine under pressure at heating condition, and is formed in a briquette  of predetermined shape.
