IPC: H04N5/44
Filed: 1984-06-14
Abstract: PURPOSE:To write a data of a required channel into a memory by taking correlation between channels having an input electric field strength at automatic search preset and applying gain control of a tuner in response to the strength of the input electric field. CONSTITUTION:A gain control section 44 is controlled by a 2-bit signal from a CPU27 and an RF.AGC to the tuner 3 is changed over into four stages. The CPU27 stores a channel selection data to a memory 28, the data is read so as to execute channel selection and the correlation between channels having the input electric field is taken at automatic search preset and the gain control of the tuner 3 is applied in response to the strength of the input electric field. Thus, a channel having a strong electric field is written in the memory 28 with priority and a channel having a weak electric field is written in the memory 28 under the control of the RF gain.

IPC: H01M8/04
Filed: 1985-06-07
Abstract: PURPOSE:To prevent unstable flow phenomena of cooling water by forming a loop for giving flow resistance to cooling fluid in the inlet of each cooling pipe. CONSTITUTION:A loop 23 is formed in each cooling pipe 7 on the inlet side of a cooling plate 5 of a plurality of cooling pipes 7 arranged in parallel, that is between an inlet manifold 9 and the cooling plate 5. The loop 23 lengthens the distance of the cooling pipe 7 from the inlet manifold 9 to the cooling plate 5 and generates the secondary flow in the cooling water and increases flow resistance of the cooling water in the cooling pipe 7. The flow resistance is produced in the cooling water by the length of pipe and the secondary flow while it flows within the loop, and pressure loss in the loop 23 prevails against that of two phase flow in the cooling plate 5 and flow rate in each cooling pipe 7 is controlled in the same level. Thereby, an electrode plate 1 is cooled almost uniformly.

Title: Multi-fuel combustion with reduced nox content
Inventor: SUZUKI TOMIO
IPC: F23C99/00
Filed: 1981-08-06
Abstract: PURPOSE:To decrease generation of NOX, by disposing a primary burner and a secondary burner adjacent to each other to one side of a combustion furnace and specifying an angle which is formed by the axes of both burners. CONSTITUTION:The crossing angle theta of the axes l1 with l2 of the primary and the secondary burners is regulated to 0-20 degrees when a cross point is at the chamber side of a combustion furnace 3, or to 0-5 degrees (not shown) when it is at the bases of both burners 1 and 2, while disposing both burners adjacent to each other and to one side of a combustion furnace 3. With such an arrangement, flames from both burners 1 and 2 are overlapped, and in the overlapped area III, generation of fuel NOX from pulverized coal is restrained, due to decrease of the partial pressure of oxygen content caused by rapid combustion of heavy oil, on the other hand, generation of thermal NOX is restrained, due to lowering of the temperature, caused by the flow of pulverized coal in the combustion areaIfor heavy oil or the like. As a result, the rate of generation of NOX at the time of multi-fuel combustion can be decreased.

Title: Manufacture of color picture receiving sereen
Inventor: JIYAN FUAN DEA UOORU
IPC: H01J9/227
Filed: 1988-05-20
Abstract: A method of producing a colour picture tube screen particularly for a high definition tube. In producing a high definition screen light from a point source (S) is directed through a segmented lens (18) and a shadow mask (24) onto a layer of photoresist applied to the internal surface of a faceplate panel (12). The segmented lens (18) comprises a rectilinear array of differently inclined facets (F). In order to obtain a substantially uniform illumination of the faceplate panel (12), the segmented lens (18) is wobbled in an oblique direction. In order to determine the optimum direction and extent of the wobbling movement, the method in accordance with the present invention involves assuming that the wobbling of the images at the screen is correct and then calculating the positions of virtual light sources to produce these images. In a first refinement of the method a raster pattern is provided on or in the lens (18) which limits the angular spread of light from each of the facets. In a second refinement the lens (18) or faceplate panel (12) is slowly displaced orthogonally to the main wobbling direction.

IPC: G01N27/62
Filed: 1978-10-11
Abstract: PURPOSE:To increase the detection accuracy for the soidum ionization detector by drawing out only the fluctuation width of the ion current to change it into the detection signal. CONSTITUTION:Load resistance 7 is provided between collector 5 and high voltage DC power source 2, and at the same time HPF8, RMS operator 9 and display part 10 are provided at the output side of resistance 7. Thus a detector is formed. In such way, the output voltage across the load resistance draws out first only the fluctuation component through HPF2. Then the necessary operation is given by operator 9 to obtain the amplitude mean value in the form of the DC output for the fluctuation component within the fixed time T. This DC output undergoes the comparison process at part 10 to have the direct display or alarm. In such way, the dark current component featuring the reduced fluctuation is cut off to eliminate the error caused by the dark current, thus increasing the detection accuracy.

Title: Jointing method for corrosion-resisting piece of turbine blade
Inventor: SUZUKI MUNENOBU
IPC: B23K26/32
Filed: 1977-10-19
Abstract: PURPOSE:To make the weld heat-affected zone disappear and to prevent the occurrence of residual stress, by  performing the build-up welding with the metal to be intermediate medium of which the coefficient of thermal  expansion is close to that of the blade material to the surface of the blade material, performing the refining heat  treatment and then jointing the metal to be the intermediate medium and the corrosion-resisting piece. CONSTITUTION:The build-up welding is performed to the roughly worked blade part 1 with the usual arc welding process. This filler metal is a material to be the metal for the intermediate medium and the alloy of Inconel  line is used for this object. With this welding, the heat-affected zone 5 is formed to the blade material and the  highest hardness at this zone reaches above 500 in Vickers hardness. Then, in order to remove this abnormal  hardened part, the refining heat treatment is carried out. As one example, by being cooled gradually after having been heated for 3 hours at 620 deg.C, the hardness of the heat-affected zone becomes about 270 and shown a  value close to the base of the blade material. Then, the finishing work is carried out and the welding is performed with the electron beam 6 while jointing with the corrosion-resisting piece 2. Because a heat source having a good efficiency of energy concentration is used at this welding, the heat affection does not reach the blade  material.
