Title: Preparation of silicon nitride powder
Inventor: ISHII MASAYUKI
IPC: C01B21/068
Filed: 1980-08-27
Abstract: PURPOSE: To prepare silicon nitride powder giving sintered silicon nitride having high density and strength, by thermally reacting a mixed powder of silica and carbon black under reduced pressure in a furnace, and then heating in a nitriding gas atmosphere.  
     CONSTITUTION: A mixture obtained by uniformly mixing 1pt.wt. of amorphous silica powder and 0.4W1.0pts.wt. of carbon powder, is heated at 1,200W1,800°C in a furnace under reduced pressure. A part of the mixture is converted to SiC by the process according to the formula I. The reaction product is further reacted in a nitriding gas (nitrogen or ammonia gas) atmosphere at 1,200W1,500°C to obtain Si 3 N 4  powder according to the reaction of formula II. The Si 3 N 4  thus prepared has low SiC content and is almost free of SiO 2  and Si 2 ON 2 . It can be formed to a dense and high- strength sintered material, which can be used as a heat-resistant structural material such as the engine parts of automobile, aircraft, etc.

Filed: 1995-04-21
Abstract: PURPOSE: To improve the operation efficiency by disposing an electric heater for melting snow falling on a moisture sensor and a temperature sensor for detecting the temperature in a moisture sensor case for supporting the moisture sensor. CONSTITUTION: When snow falls on the pavement surface 11 of a pavement part 10, the snow is melted by the heat of an electric heater 7 in a moisture sensor case 4 to be changed into water. Subsequently, electric resistance between the anode 1 and cathode 2 of a moisture sensor is decreased by the water, and the change of electric resistance is transmitted to a road heater control board by the moisture sensor. Subsequently, the control boards turns off the application of an electric current to the electric heater 7. When a temperature sensor 5 in the moisture sensor case 4 detects a temperature below the preset temperature T1 , the sensor transmits the temperature to the control board. Further, the control board applies an electric current to the road heater 9 to melt the snow falling on the road surface.  If there is no detection of moisture by the moisture sensor, an electric current is not applied to the road heater 9, and if the temperature sensor 5 to the electric heater 7 detects a temperature below the preset operating temperature T2 , an electric current is applied.

Abstract: PURPOSE:To enable to accomplish effective utilization of a substrate and highly efficient groove processing works by a method wherein the groove for isolation is formed into U-type from the convensional V-type, thereby enabling to make narrower the groove width to a high degree. CONSTITUTION:After an isolation groove 12 has been formed, a dielectric film 13 is formed by performing a thermal oxidization, and then a poly silicon 14 is deposited by performing a CVD method. The single crystal silicon 16 located on the part, where an element will be formed, is formed into an island isolated by a dielectric by performing a grinding work on the dielectric film 13 in such a manner that the upper part of it will be exposed. As the isolation groove is formed on the single crystal silicon 11 by performing a machine work, the width of groove can be made narrower than that of the conventional groove which is formed by performing an etching. The conventional groove has approximately 60-70mum in width, whereas the width of the above groove can be narrowed to 20-30mum, thereby enabling to effectively utilize the substrate and to perform processing works in a mass productive manner.

Abstract: PROBLEM TO BE SOLVED: To achieve stable performance over a long term without causing the deterioration of the performance of toner by making (elastic energy)/((elastic energy)+(plastic energy)) obtained from the deformation recovering behavior of the surface of a member >= a specified value. SOLUTION: Surface material is adjusted so that (elastic energy)/((elastic energy)+(plastic energy)) obtained from the deformation recovering behavior of the surface of the member in the case of measuring the universal hardness of the surface of the member may be >=0.4. In the case of an outermost layer forming the surface of the member, fluororesin is desirably used as an outer layer from the viewpoint of the surface smoothness of the member and the low tightness with a body to be electrified. By adding conductive agent, conductivity is applied or adjusted in the outer layer, and it is desirable to use carbon in the case of the outermost layer. It is desirable to set the thickness of the outer layer to <30 μm, especially, 1 to 15 μm.

Abstract: PURPOSE:To foresee a thaw end time during thawing and to suitably thaw food by ringing a thaw buzzer before a predetermined time from the end of integrating a predetemined time of a thaw timer. CONSTITUTION:If it becomes a time before predetermined time (e.g. 5min) from predetermined time (e.g. 30min), a thaw timer 26 stores to set ON and to reset OFF in a thaw buzzer 25 in a RAN 18. The timer 26 is turned ON to integrate time. It outputs the states of a thaw heater 13 and the buzzer 25, but since the heater 13 is set to ON here, a transistor 21 is turned ON to conduct a relay coil 22 thereby to close a relay contact 23. Thus, the operations of the heater 13 and an auxiliary motor-driven blower 12 are continued to proceed thawing. The buzzer 25 turns a transistor 24 ON due to the ON state before predetermined time (e.g. 5min) of predetermined time (e.g. 30min) to ring the buzzer 25.
