Title: Combustion reducing production of nitrogen oxide
Inventor: SAKAI MASAYASU
IPC: F23C99/00
Filed: 1983-07-18
Abstract: PURPOSE:To enable effective reduction of the generation of NOx without increase in the height of a boiler, by a method wherein auxiliary air is fed through a position wherein the feed positions of the fuel and the air for combustion will never be superposed with the feed position of the auxiliary air. CONSTITUTION:An auxiliary air compartment 104 is disposed in a level equal to or higher than that of the topmost stage part of a main burner 103 to the wall surface of a furnace except an axis part extending in the injection direction of the fuel. An auxiliary air 109 through said auxiliary air compartment 104 is fed in a position which is not superposed with the main fuel feeding position of the main burner in the furnace, and this reduces the production of NOx. This constitution permits reduction of a distance L between the auxiliary air compartment 104 and the center of the main burner 103 in such condition that an effect of reducing the production of NOx compares favourably with that brought by a conventional one.

Title: Packed column for liquid chromatograph and method for filling solid-phase material
Inventor: ITO AKIYUKI
IPC: G01N30/56
Filed: 1988-05-27
Abstract: PURPOSE:To make the pressure of a solid-phase material uniform and to obtain high performance, by inserting a chromatographic tube comprising a material having a small elastic modulus into an outer tube, and compressing the solid-phase material in the chromatographic tube and the chromatographic tube itself in the axial direction. CONSTITUTION:A small diameter part 13a at the inner end side of a flange 13 is inserted into the end part of a chromatographic tube 11 comprising a material having a small elastic modulus. Under this state, the part 13a and the chromatographic tube 11 are inserted together into an outer tube 12. A medium diameter part 13b is inserted into the end part of the outer tube 12. A large diameter part 13c is compressed tightly to a flange part 12b. Then, a step part 13d between the small diameter part 13a and the intermediate diameter part 13b copresses the end part of the tube 11 and a taper ring 16 in the axial direction. At the same time, a slant surface part 12e at the inner surface of the end part of the outer tube 12 compresses the ring 16 into the shorter diameter. The end part of the tube 11 is compressed to the outer surface of the small diameter part 13a, and the tube 11 is fixed. Then, the tube 11 is fully filled with a solid-phase material C (particles). Under this state, a piston 14 is pushed in the axial direction so as to compress the tube 11 and the solid-phase material C. A cap 15 is tightened until a collor 28 hits the piston 14. Thus, the piston 14 is fixed.

Title: Character insertion circuit
Inventor: YOSHIDA YUKIHIRO
IPC: H04N5/278
Filed: 1993-05-31
Abstract: PURPOSE:To improve the picture quality of character video by interrupting the high band components of a character signal when video data into which characters are inserted is prepared. CONSTITUTION:When a video signal input part 1 receives a video signal and a date signal input part 2 receives a date signal, the video signal and the date signal are transmitted to a date insertion circuit 3, the date insertion circuit 3 inserts the video signal into the date signal and a mixed signal is generated. The mixed signal is transmitted to a low-pass filter 4, the low-pass filter 4 interrupts the high band components and outputs the mixed signal to the input terminal A1 of an analog switch 5 in a state that the edge is weakened as a whole. A video signal output part 1 outputs the video signal as it is without performing any processing to the input terminal B1 of the analog switch 5. The analog switch 5 switches the input to the input terminal A1 and outputs the output signal of the low-pass filter 4 to a pre-emphasis circuit 6, only when the switch 5 receives the character signal inserted in the mixed signal.

Title: Head carriage moving device in magnetic recording/ reproducing device
Inventor: NEGISHI KENJI
IPC: G11B21/02
Filed: 1987-05-28
Abstract: PURPOSE:To save the space by approaching a spindle and a lead screw for head carriage movement. CONSTITUTION:The position of the screw part 21 of the lead screw 20 exists at one end. The needle 22 engaging with the root of the screw 21 has only to be provided to the end of the head carriage 10 and it is not required to provide the part to fix the both ends of the needle 22 to the middle part of the head carriage 10.

Title: File retrieving device
Inventor: SHIBAYAMA SHIGEKI
IPC: G06F17/30
Filed: 1988-05-30
Abstract: PURPOSE:To retrieve a desired file without putting a burden on a user by retrieving the file using an association by image information even when the user forgets the name of the file. CONSTITUTION:An image generating means retains the image information generated either based on designation by the user or automatically under a corresponding state to the file generated by the user. Further, the retained file can be retrieved by designating the image information accompanying the file. This kind of image information is, for example, a symbol, a graphic, a color, etc., and the image information becomes an important key in order to associate the file with the image information. Consequently, a system side generates the image information for awakening an appropriate association and accompanies the file with the information, which is extremely effective as the key for retrieving the file. Thus, the generated file can be easily retrieved afterward without increasing the burden on the user.

Filed: 1984-06-25
Abstract: PURPOSE:To calibrate belt weir with high accuracy by forming belt conveyors provided with belt weirs to be calibrated and a belt conveyor provided with a reference belt weir in a closed loop, and comparing their measured values. CONSTITUTION:For example, when (n) sets of belt weirs are calibrated, belt conveyors including the belt weirs B1-Bn to be calibrated and a reference belt weir B0 which is calibrated previously with high accuracy are formed in the closed loop 1. Then, a raw material is flowed from a raw material storage tank 2 to the closed loop 1 at the 1st transport level (t/hr) and measured by the reference belt weir B0 and belt weirs B0, B1-Bn to be calibrated. Then, the raw material is flowed at the 2nd transport level and measured similarly by the belt weirs B0, B1-Bn. Then, a processor compares measured values of the objective belt weirs B1-Bn with that of the reference belt weir B0 at each level to correct the measured values of the belt weirs B1-Bn. Therefore, measurements of the belt weirs are taken easily with high accuracy and this is useful for an ore yard.

IPC: H05K3/34
Filed: 1987-05-27
Abstract: PURPOSE:To form solder protuberances at least two positions, and to inhibit the displacement of a surface mounting part on mounting by dividing a pad into a section, on which solder is applied, and a section, on which solder is not applied, in a printed wiring board for surface mounting. CONSTITUTION:Terminals 11 for a surface mounting part 10 are placed at specified positions on pads 12 with sections 13, on which solder is applied, and sections 14, on which solder is not applied and from which conductors are exposed. Consequently, one terminals 11 are not moved because they are supported under a stable state by two or more of solder protuberances 13. The terminals 11 for the surface mounting part 10 and the pads 12 are connected with solder by charging a substrate, on which the surface mounting part 10 is arranged, in solder melting environment, and excess solder flows into the sections 14 from which the conductors are exposed. Accordingly, the terminals 11 for the surface mounting parts 10 and the pads 12 can be connected positively, and short circuits among the pads 12 due to excess solder can also be prevented.
