Abstract: PURPOSE:To make it possible to control the width of a gate electrode with high accuracy by a method wherein when a gate metal film is formed at a scheduled gate electrode formation site adjacent to a step consisting of a gate mask film, the film thickness of the gate metal film at this site is controlled. CONSTITUTION:An active layer 14 is formed in a desired part of a semiconductor substrate 11. Then, a gate mask film 15 is applied and formed on the whole surface of the substrate 11. Then, an undesired part of the film 15 is etched away and a step 17 consisting of the film 15 is formed on the layer 14. Then, a gate metal film 18 is applied and formed on the whole surface of the substrate 11 including the film 15 in a prescribed film thickness by controlling the film thickness of the film 18. At this time, the width (l), which is located at a scheduled gate electrode formation site adjacent to the step 17 consisting of the film 15, of the film 18 can be set with high accuracy by controlling the film thickness of the film 18. After that, the whole surface of the film 18 is subjected to anisotropic dry etching to remove an undesired part of the film 18, the film 18 is made to remain at the scheduled gate electrode formation site, which is adjacent to the step 17 and is positioned on the layer 14, and a gate electrode 19 is formed.

Abstract: PURPOSE:To reduce manufacturing costs by making built-in a circuit part, which drives a light emitting element, and a signal processing unit, which converts an optical current from a light receiving element into a voltage signal, integrating the signal, then comparing it with a reference level, discriminating it, and outputting a trigger signal. CONSTITUTION:Inside a signal processing unit 4, a reference pulse generating circuit 46, which intermittently drives the light emitting element in a constant cycle, and a driving circuit 47 are provided. The signal inputted from a signal input terminal IN of the unit 4 is converted into the voltage signal by an I/V converter 41, then amplified 42, and integrated by an integrator 43. The integrated signal is inputted through a comparator 44 to a discriminating circuit 45, and the magnitude levels with respect to the reference signal is discriminated. In such a configuration, the unit 4 outputs a pulse signal from an output terminal OUT 1 in the constant cycle in order to drive an LED, the unit 4 receives the optical current sent from a photo diode through a terminal IN, and when the integration output amounts to the reference level, the trigger signal is outputted. Thus the one-signal type and two-signal type smoke sensor can be composed by using the unit 4.

IPC: C21B11/02
Filed: 1992-03-02
Abstract: PURPOSE:To separately discharge molten iron and slag without separating a molten iron discharging hole and a molten slag discharging hole or tilting a furnace by raising basicity and temp. of the slag and discharging the slag after precedingly discharging the molten iron from the discharging hole, by utilizing difference of the viscosity between the molten iron and the slag in the cylindrical furnace. CONSTITUTION:Coke packing layer 7 is formed from the furnace bottom of the cylindrical furnace 1 to the level containing primary tuyeres 3. On this coke packing layer, iron ore and/or scrap packing layer 8 are formed to the level of secondary tuyeres 4. Successively, by injecting assist gas and fuel from the tuyeres 3, 4, these materials are continuously melted. Then, while making the slag with low basicity and low fluidity, the molten iron 9 produced by one heat quantity is discharged from the discharging hole 6. Further, when the low fluidity slag quantity reaches to the reference value, the basicity and/or the temp. of the slag in the furnace are raised, the viscosity of the slag is lowered and the slag is discharged from the discharging hole 6.

This Na 4 is applied from a pouring port 5 arranged at one end of the cavity part 3 and then sealed with a cover 6. The sealed Na 4 is liquefied with heat received by the top face of the piston at the low melting point of 93 deg.C. Na 4 is then stirred inside the cavity 3 and heat received by the top face difused toward the skirt of the lower part to lower the temp. at the top face and cancel heat unbalance in the piston 1 itself. It is thus possible to prevent occurrence of trouble such as scuffing of the piston and the like and lighten weight so as to decrease inertia.
