IPC: A47J27/00
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To cook delicious rice with a sweet taste by increasing a carbohydrate content of rice by installing the first heating controller which controls a heating means to maintain a pan to a pre-determined impasting temperature and the second heating controller which completes cooking by controlling heating means after the impasting time elapses. SOLUTION: A control circuit board 8 has the first heating controller 15 in order to maintain a pre-determined impasting temperature and a measurement signal from a temperature sensor 7 is inputted by means of a temperature detector 14. The first heating controller 15 controls the input of a coil 6 and maintains the pan 3 to the pre-determined imputing temperature. An impasting temperature is established by an impasting temperature setting means 17 beforehand. The setting time may be changed by a step of 5 minutes by way of the setting means 18 which establishes the time for setting an impasting time. When the control of the first heating controller 15 is over, the second heating controller 20 drives a coil drive means 16 based on the measurement signal of the temperature sensor 7, generates alternating magnetic field in the coil 6 and controls the heating of the pan 3.

Abstract: PURPOSE:To make it possible to form projected and recessed parts on the surface of a polycrystalline silicon film in a stable and easy manner by forming a silicon oxide film whose film thickness is greater than that of a grain section on a grain boundary section of the polycrystalline silicon film and then etching the silicon oxide film and polycrystalline silicon film. CONSTITUTION:The surface if a polycrystalline silicon film 2 is esposed to oxygen plasma and slightly oxidized, which forms a silicon oxide film 5 on the surface of the polycrystalline silicon film 2. During this formation, the silicon oxide film 5 is formed on a grain boundary section 3 rather than a grain section 4. Then, the silicon oxide film 3 and a part of the polycrystalline silicon film 2 are etched with reactive ions, using HBr gas-based plasma which is anisotropic etching. Under this etching condition, the etching speed of the polycrystalline silicon film 2 is sufficiently large compared with the etching speed of the silicon oxide film 5. As a result, only the upper part of a clad section of the polycrystalline silicon film 2 can be removed by etching, which produced projected and recessed parts on the surface of the polycrystalline silicon film 2, then removes the silicon oxide film 5, thereby forming a number of projected and recessed parts with ease.

Also a contact prevention layer 28 composed of SiO2 film, etc., is formed between the luminous segment electrode 21 and an insulation layer 24. Consequently the Al wiring pattern 21, etc., is not corroded by the insulation layer 24 or external water and other dirt, etc. Moreover because the prevention layer 28 is an insulation substance structurally and it is needed to select one not including impurities such as alkali ion, etc., for example a SiO2 film is used, and at the time of Al wiring, a film is formed using low-temperature plasma CVD. This permits obtaining a dot array tube in which luminous brightness is not lowered and luminous nonuniformity is not produced.
