Title: Method for preventing explosion during reduction of stock line and blowing down of blast furnace
Inventor: KAMATA MITSUO
IPC: C21B5/00
Filed: 1980-05-27
Abstract: PURPOSE:To prevent the explosion of furnace top gas at the time of resuming blast furnace operation by increasing the stock line by sampling the gases from the plural places in the circumferential direction in the cavity parts in the mid part of a shaft or bosh and measuring the same after reducing the stock line and blowing down of a blast furnace. CONSTITUTION:After reduction of the stock line and blowing down, gases are sampled from the plural places in the circumferential direction in the cavity parts in the mid part of a shaft or bosh, and the gas components contg. a large amount of CO and H2 in said cavity parts in the lower part of the furnace where substitution of the gases with steam or N2 is difficult are detected. In this case, the gases are sampled at >=2 placed in the circumferential direction of the cavity parts, and more preferably the gases are detected from six equidistantly spaced parts at the same height level of the position 1-6m above the charge line after the reduction of the stock line. As a result, the gas components within the local gas explosion limits are accurately detected and gas explosion is perfectly prevented.

Title: Electron beam generating apparatus
Inventor: SHIRATORI TETSUYA
IPC: H01J31/12
Filed: 1989-03-22
Abstract: PURPOSE:To make it possible to display images without vibration even when a vibration is generated by bringing a supporting material having a prescribed controlling plane into contact with a linear cathode comprised of a linear core wire and a wire coiled on the core spirally and a coating of an oxide radiating material on the wire. CONSTITUTION:Controlling planes 4aa, 4ab of a supporting parts 4a, 4b have 2 effects. One is that a resonance state is hardly caused since the linear cathode 3 is in contact with the supporting parts 4a, 4b and the contacting planes 4ab, 4bb and 4ac, 4bc are reciprocally replaced each other to form node when vibration is generated. The other is that vibration energy is absorbed within a short period and the vibration is damped owing to friction resistance between the cathode 3 and supporting parts 4a, 4b. Since the cathode 3 has a spirally coiled wire 3b, friction resistance functions against displacement in any directions. Moreover the length of the cathode 3 is elongated for a large scale screen, vibration is prevented by the same supporting parts.

Filed: 1989-03-22
Abstract: PURPOSE:To simplify the circuit by fetching an n-line of data strings equivalent to m-highway, using a serial parallel conversion circuit so as to apply multiplexing to the data by m-highway as one data row and applying multiplex processing in time division for the CRC arithmetic operation of each line. CONSTITUTION:A serial parallel conversion circuit fetches n-line of data row equivalent to m-highway to form one data row with time division multiplex. Then a CRC arithmetic circuit 12, a memory 13, a shift register 17, a pulse generating circuit 19 and a selection circuit 18 apply multiplex processing in time division to the CRC arithmetic operation of each line as to the data row subject to time division multiplex. Thus, the CRC code is able to be generated by one CRC arithmetic circuit without provision of the CRC arithmetic circuit as to each line to simplify the circuit.

Abstract: PURPOSE:To efficiently execute the transmission of an image signal to an external device from a read means by controlling writing in an image memory based on an internal synchronizing signal and controlling reading from the image memory based on an external synchronizing signal. CONSTITUTION:In case of a write mode, image information read by a CCD 1 is subjected to address control by an address counter 18 and stored in an image memory 16 sequentially.

Filed: 1988-03-24
Abstract: PURPOSE:To improve superconductive characteristic by mixing two material oxides of specific compositional ratios together, processing with press forming, sintering to form a complex body, removing a metallic pipe after diameter reduction process, and applying heat treatment. CONSTITUTION:A material of the compositional ratio of A2B1Cu1O5 and a material of the compositional ratio of B3Cu5Oy (where y=5-15) are mixed together with the ratio of (1+X):1 (where o<X<=0.5). The mixture is press- formed to obtain a press-formed body which is sintered to obtain a precursor of an oxide-based superconductor. The precursor is packed into a metallic pipe to form a complex body and the diameter of which is reduced. After the diameter reducing process, the metallic pipe is removed. The product is heat treated. (The element A is in the group IIIa and the element B is in the group IIa). This makes it possible to obtain an oxide-based superconductor having excellent superconductive characteristic such as the critical current with a high efficiency.

Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To reduce a layout area by supplying a boosted clock signal only to a booster stage on the post stage side and suppressing voltage drop due to back gate effect thereby boosting a low power supply voltage to a high voltage. SOLUTION: In response to external clock signals CLK1, CLK3, a clock signal booster circuit BSTCRCT generates boosted clock signals BSTCLK1, BSTCLK3 having the same phase as the clock signals and an amplitude boosted above a power supply voltage Vcc. On each booster stage stg5-stg8 constituting the post-stage side, a capacitor C1 for increasing the gate voltage of an N channel MOS transistor N2 is applied with the boosted clock signals BSTCLK1, BSTCLK3. Consequently, the power supply voltage Vcc is boosted substantially equally at each booster stage stg5-stg8. Each booster stage stg1-stg4 constituting the post-stage side is applied with the external clock signals CLK1, CLK3 in order to prevent increase of the layout area.

Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To easily construct a duplex of a system, to disconnect a fault node from a network and to improve reliability of the network. SOLUTION: A fault detection circuit 2 detects the frequent occurrence of reception data abnormality such as an FCS(frame check sequencer) error or the like in a received packet, the abnormality of a transmission line such as disconnection or the like and the abnormality of a node such as frequent occurrence of collision or the like and informs a switch controller 6 of the detection of the fault.

Filed: 1990-03-20
Abstract: PURPOSE:To improve the recognition rate by removing an abnormal reflected light area from the object to perform comparison and collation at the time of the existence of this area in a scan area and removing a drop-out part from the object to perform coincidence discrimination at the time of the occurrence of partial drop-out in a read input character pattern due to an interposed transparent medium. CONSTITUTION:If the abnormal reflected light area exists, the signal level in an area X of an electric signal is higher than the normal paper surface level and is outputted to a binarizing circuit 20 and an abnormal reflected light area detecting circuit 50, and a binarized picture signal is outputted to a character extracting circuit 30. The character extracting circuit 30 normalizes a character to a fixed size by the inputted picture signal and inputs the result to one input of a collating and discriminating circuit 40. The abnormal reflected light area detecting circuit 50 binarizes the signal based on the paper surface level to detect the abnormal reflected light area and outputs it to an abnormal reflected area position detecting circuit 60 to determine whether the abnormal reflected light area exists or not. The collating and discriminating circuit 40 discriminates the character by pattern matching between standard character patterns and the normalized signal, and the area position is removed from the object of pattern matching.
