Title: Ceramic thermally sprayed member
Inventor: MIYAMOTO NORITAKA
IPC: C23C4/10
Filed: 1987-05-01
Abstract: PURPOSE:To improve the durability of the title member in a high-temp. corrosive atmosphere and to provide excellent heat insulating property and heat resistance by thermally spraying a first layer of zirconia and a second layer of alumina, titania, etc. through a thermally sprayed substrate layer having good adhesion to ceramics on a metallic base material. CONSTITUTION:The thermally sprayed substrate layer 2 of an Ni-based alloy, etc., having good adhesion to ceramics is formed on the surface of the metallic base material 1. The first ceramic thermally sprayed layer 3 consisting of zirconia is then formed thereon, and the second ceramic thermally sprayed layer 4 consisting of >=1 kind among alumina, titania, or spinel is formed thereon. Alternatively, a grated thermally sprayed layer 5 consisting of >=1 kind among zirconia, alumina, titania, and spinel and wherein the zirconia content is decreased from the first thermally sprayed layer 3 side to the surface side is formed on the first thermally sprayed layer 3, and then the above-mentioned second thermally sprayed layer 4 is formed. By this method, the infiltration of the external air is prevented, and the release of the ceramic thermally sprayed layer due to the oxidation and corrosion of the thermally sprayed substrate layer 2 can be prevented.

Title: Effective channel identification circuit
Inventor: YAJIMA YOSHIYUKI
IPC: H04L12/70
Filed: 1994-05-23
Abstract: PURPOSE:To obtain a signal identifying the channel effectiveness of received data on which the content of a channel identifier is affected by comparing a value of channel identifier in the received data with a specific value held with a specific value holding means. CONSTITUTION:The specific value holding means 4 holds one or more specific values of the channel identifier in which no or only a part of information is included in a degenerate channel identifier. A comparison means 5 judges whether or not the value of channel identifier in the received data coincides with the specific value held with the means 4. An omission channel identifier information affecting means 6 outputs signals to maintain or neglect compulsorily the channel effectiveness result of the received data obtained based on the degenerate channel identifier corresponding to the judged result of the means 5. Therefore, the signal representing the channel effectiveness of the received data on which the content of the channel identifier is affected can be obtained even when no information of channel identifier in the degenerate channel identifier exists.

Title: Semiconductor memory device and its manufacture
Inventor: MAEJIMA TAKASHI
IPC: H01L21/8247
Filed: 1995-05-02
Abstract: PURPOSE: To provide a semiconductor memory device wherein the number of times of data rewriting is largely increased, and provide further a manufacturing method of the device. CONSTITUTION: The title manufacturing method consists of a process wherein a floating gate 2 and a control gate 1 are formed, by etching, on a tunnel oxide film 4 formed on a semiconductor substrate 5, and a process wherein oxidation is performed under the condition where the tunnel oxide film 4 is left on the periphery of the floating gate 2 of the semiconductor substrate 5, and an oxide film 6 is formed on the whole surface. Since the excellent tunnel oxide film 4 which is eliminated in a conventional memory cell forming process is left at a gate edge part which is periphery of the stray gate 2 of the semiconductor substrate 5, surface energy level is hardly generated, and hot electrodes generated in case of writing and trapped charges of a tunnel current into the oxide film in case of erasing can be reduced.

Title: Continuous production device for vapor-phase epitaxial growth carbon fiber and continuous production of vapor-phase growth epitaxial carbon fiber
Inventor: HARADA MINORU
IPC: D01F9/133
Filed: 1995-05-02
Abstract: PURPOSE: To produce a vapor-phase growth carbon fiber in high yield and to enable continuous operation for a long period of time by installing a raw material gas feed nozzle at one end of a reaction tube and fixing a second gas feed opening at the outside of a gas feed opening laid at the outside of the raw material gas feed nozzle. CONSTITUTION: When the temperature of a first gas heated by a first heating means is made higher than that of a raw material gas jetted from a raw material gas feed nozzle 10, no convection will occur between the first gas and the raw material gas, consequently, the first gas and the raw material gas become a communicating state resembling a piston flow. Further, a second gas flow whose flow rate is adjusted by a third mask flow controller 8 is introduced to a second gas feed opening 14 and sent from the second gas feed opening 14 to a reaction tube 11. The second gas is then passed through a gap between the outer peripheral face of an inner peripheral tube 12 and the inner peripheral face of the reaction tube 11 and introduced to a vapor-phase growing carbon fiber forming zone.  A transition metal compound and an organic compound in the introduced raw material gas are decomposed by energy fed from an electric furnace 15 consequently, a vapor-phase grown carbon fiber is formed by the action of a catalytic metal and the fiber is gathered in a collecting box 16.

Abstract: PURPOSE:To restrain variations in the air-fuel ratio, by dividing the operating range of feed-back control into a plurality of sub-ranges so that the feed-back control is initiated when the operating range is shifted, in accordance with the coefficient value of the objective range. CONSTITUTION:In an air-fuel ratio feed-back control operating range, a basic fuel injection time which is obtained by an ECU5 in accordance with the outputs of a rotating angle sensor 11 and an intake-air pressure sensor 8, is compensated in accordance with a compensating coefficient, etc. obtained from the output of an O2 sensor 15 so that the injection time of a fuel injection valve 6 is controlled. In this stage, the above-mentioned operating range is divided into a plurality of sub-ranges, and the averaged value of the above-mentioned compensating coefficients is calculated and memorized when the operating range is in the O2 sensor feed-back control operating range. When the operating range is shifted from the first range (idle operation range) to the O2 sensor feed-back operating range, control is made such that the air-fuel ratio feed-back control is initiated with the use of the above-mentioned averaged value as a compensating value.

Filed: 1981-07-13
Abstract: PURPOSE:To prevent the generation of burrs and improve work efficiency by equalizing the sum of volume of concavities of the upper and lower dies with the volume of plastic worked parts of a blank material. CONSTITUTION:The width of the concavity 21 of an upper die 20 is made greatter than the diameter D of a material 9, and the sectional form of the concavity 22 of a lower die 23 is made nearly semicircular, and the radius of curvature is made greater than the diameter D. The sum of volume of the two concavities is made substantially equal to the volume of plastic worked part of the material 9. Accordingly, when the material 9 is pressed between the upper die 20 and lower die 22, rack teeth are cut on its upper surface. At the same time, the lower surface is plastic worked along the concavity 23 and the diameter is increased slightly. Thus, the generation of burrs can be prevented.

Title: Method of intensely burning solid fuel particle
Inventor: BIKINGU BARENTEIN DEMAARU
IPC: F23B99/00
Filed: 1980-08-11
Abstract: Solid fuel such as coal is fed into an inlet shaft of the furnace through a rotary feeder constructed to prevent the admission of air. Primary air channels supply the major part of the air required for combustion of the fuel in a region in which the fuel bed is sufficiently thick to avoid disturbance and the formation of "holes" by this air. Further, narrower air channels supply sufficient, diffused and low velocity air to complete the combustion of the fuel without substantial entrainment of grit and ash. Air is prevented from flowing in contact with the fuel up stream of the primary channels and the metering edge.

Abstract: PURPOSE:To improve the quality of a clad material and to extend the life of a bushing member by forming essentially said member of at least >=1 kinds among zirconia, silicon carbide and silicon nitride ceramics. CONSTITUTION:The bushing member A is formed of the ceramic material consisting substantially and essentially of at least >=1 kinds among the zirconia, silicon carbide and silicon nitride ceramics. The member A is calcined of the pulverous powder consisting of several mu - fractions of ten mu.
