Title: Low nox burner
Inventor: TSUBOI HIDEFUMI
IPC: F23D14/08
Filed: 1993-04-09
Abstract: PURPOSE:To obtain a low NOx burner which is stable and excellent in burning fuel across a wide range of turndown ratio, by a method wherein the primary excess air ratio of thin-fuel premixed gas blown from thin-fuel burner ports is highest at the central part of the thin-fuel burner port group and gradually lowered toward a thick-fuel burner port group located away from the central part. CONSTITUTION:As thin-fuel premixed gas diluted with air in a dilution section 7 is premixed with thick-fuel premixed gas which is introduced from a concentrically-circular thick-fuel premixed gas introducing port 11 and diluted with air supplied from the central part, the primary excess air ratio of a thin- fuel premixed gas burner port group 2 is highest at the central part and gradually lowered toward a thick-fuel gas burner port group 4. Therefore, during maximum combustion, a low NOx combustion is attained because of thick- and thin-fuel combustion, and during minimum combustion, stable thin-fuel flames are formed on thin-fuel burner ports 1 on the thick-fuel burner port group 4 side that is away from the central part. As a result, the stable thin-fuel flame group is formed on the thin-fuel burner port group 2, so that a lift does not occur and CO and HC are not generated.

Title: Superconducting logic element
Inventor: SAKAMOTO YOSHIKI
IPC: H03K19/195
Filed: 1988-04-05
Abstract: PURPOSE:To execute a logic action equal to that of a resistance load type nMOS inverter by connecting a superconducting material and an electric resistance in series and controlling the intensity of a magnetic field impressed to the superconducting material. CONSTITUTION:When an input signal High is impressed to an input 7, a magnetic field 6 generated with a current decided by an electric resistance 5 is given to a superconducting material 3, the superconducting material 3 executes a transition to a constant conducting condition, it is made to have a resistance value to be sufficiently larger than a load resistance 4, and an output 8 is made into an output signal Low. On the other hand, when an input signal Low is impressed to the input 7, the magnetic field 6 is not generated, the superconducting material 3 remains in a superconducting condition, an electric resistance value is zero, and thereby, an output signal High by the load resistance 4 is outputted to the output 8. Thus, the action of the inverter can be executed by the superconducting material and electric resistance.

IPC: G01F23/30
Filed: 1990-03-30
Abstract: PURPOSE:To obtain the detecting device of simple constitution which has superior high-temperature resistance and a small temperature drift and can detect a liquid level position with high accuracy without being affected by a flow of the molten metal by detecting the liquid level of the molten metal as the buoyancy of the molten metal. CONSTITUTION:The buoyancy of the molten metal 2 in a molten metal tank 1 is received by a probe 3 intruding into the molten metal tank 1 and transmitted to an arm 4, and further transmitted to a buoyancy detector 6 from the other end part 4b of the arm 4. In this case, the other end part 4b of the arm 4 contacts the buoyancy detector 6, so the arm 4 rotates only by a fine angle which is invisible even when receiving the buoyancy, which is transmitted to and detected by the buoyancy detector 6. The detected buoyancy is outputted as an electric signal, external noises in the signal are removed by a filter 8, and an arithmetic processor 7 further performs arithmetic processing to calculate the liquid level of the molten metal corresponding to the buoyancy detected by the buoyancy detector 6.

Title: Operation lever
Inventor: YOSHINAGA SEIJI
IPC: G05G1/04
Filed: 1986-04-10
Abstract: PURPOSE:To set operation power even over a whole operation range by setting the height of the top part of an uneven part in an intermediate part of the operation range from a lever surface higher than those of both side parts. CONSTITUTION:In the uneven part 12, the height from the surface of the lever 1 of the top part is set larger than that from both side parts to the intermediate part of the operation range of the lever 1. In such a case, the height from the bottom is constant over the whole operation range and each uneven shape is the same. Thus, the height of a projecting part 9 in the lever 1, which is engaged with the uneven part 12 in the intermediate part from the surface of the lever 1 is higher than those of the both side parts, whereby the bending of a flat spring 8 comes to bend wide and its energizing power increases. Consequently, the power in an operation direction, which the projecting part 9 needs to get over the projecting part of the uneven part 12, becomes larger, and the control power must be strengthened accordingly. For operating the operation lever 1 from both side parts to the intermediate part, the operation power does not change but in becomes constant.

IPC: G06T15/80
Filed: 1986-04-11
Abstract: PURPOSE:To delete undesired processing to an object element that could not be discriminated on a picture and to increase picture producing speed, by setting the observing conditions and selecting the desired one of those form data on the objects. CONSTITUTION:The observing condition setting data are supplied to a setting part 7 and the observing conditions are set for a visual point, a virtual picture, etc. Then the form data are selectively read out 3 of a form data store part 1. An calculating part 2 calculates the ratio alpha between the sizes of the picture and an object image based on the setting conditions and the form data. The level is decided 4 for the object element which produces a shadow picture based on an alpha-level correspondence table 5 between the ratio alpha and the object element level. Thus a shadow picture is produced 6 from the prescribed form data. Therefore the quantity of data stored in a shadow picture production processing part 6 can be reduced by extracting previously the form data on the object elements of levels up to that corresponding to the relevant object out of the part 1 via an object form reading part 3 based on the decided 4 result for all objects included in a subject scene.
