Title: Heat treatment furnace for metal strip and heat treatment method
Inventor: MATSUMURA ICHIRO
IPC: C21D9/63
Filed: 1994-03-15
Abstract: PURPOSE:To enable operating of heat treatment while floating up a metal strip with gas during carrying the metal strip so as not to damage and receive unnecessary tension to the metal strip and to assist the float-up with supporting rolls, when a shortage of the float-up force is caused by a size or a material of the metal strip or by a furnace condition in the circumferences. CONSTITUTION:Float-up nozzles 5 are disposed along a carrying path 1 of the metal strip, and also, metal strip supporting rollers 9 are interposed mutually between the float-up nozzles 5 so as to be vertically moved by selecting whether or not the support to the metal strip is necessary to supplement the shortage of the float-up force to the metal strip with the supporting rollers 9. By this method, the damaging to the lower surface of the metal strip 3 is reduced.

Title: Fluid coupling device
Inventor: IWAO NOBUYUKI
IPC: F16H41/30
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To reduce drag torque without impairing a torque transmitting function by providing a working fluid pressure adjusting means for adjusting fluid pressure of a feeding working fluid so as to become almost equal to circulating force of the working fluid in an operating chamber at idling rotation time of an internal combustion engine. SOLUTION: In a fluid circuit, a relief valve 74 is arranged in a relief passage 73. The relief valve 74 is set so that valve opening pressure becomes almost equal to circulating force of a working fluid in an operating chamber 4a at idling rotation time of a diesel engine. That is, the valve opening pressure of the relief valve 74 is set so as to become almost equal to circulating force generated by centrifugal force of the working fluid generated by rotation of a pump 42 driven by the diesel engine. Thus, the relief valve 74 functions as a working fluid pressure adjusting means for adjusting fluid pressure of the working fluid fed from a fluid pressure source so as to become almost equal to circulating force of the working fluid in the operating chamber 4a at idling rotation time of an internal combustion engine.

IPC: G06F17/30
Filed: 1990-03-20
Abstract: PURPOSE:To commonly utilize the image information of a diagram, table and document and to reduce memory capacity by uniquely controlling the image information of the diagram, table and document. CONSTITUTION:In respective sections, the dispatched source diagram, table and document image information is sent to a control section. An input controller 4 inputs the dispatched image information of the diagram, table and document, registers the information to an image file 11 while attaching a unique name and registers the attribute information of the image information to an attribute file 10. When executing retrieval, the desired image information is inputted from a key input device 15 while attaching the attribute as a condition. A message controller 3 dispatches this attribute information to a retrieval controller 5 and based on the attribute information, the retrieval controller 5 retrieves the attribute file 10 and the retrieved result is passed through the message controller 3 again and displayed on a display device 14. Thus, the image information of the diagram, table and document can be commonly utilized and the memory capacity can be reduced.

Title: Houling suppressor
Inventor: FUJIMOTO YUKIHIRO
IPC: H04M9/08
Filed: 1988-03-25
Abstract: PURPOSE:To suppress houling automatically by inferring, in the case there is a difference between and output signal from a first subtractor and that from a second subtractor, the respective impulse responses by a first and a second impulse response inferring circuit so as to make said difference come to zero, and generating a pseudo echo. CONSTITUTION:If the ambient temperature varies or preliminarily-inferred impulse responses H1, H2 varies because of the moving of the positions of microphones 1, 2 and a speaker 6, the output level of the subtractor 3a changes. The impulse response inferring circuits 3, 4 newly speculates the impulse responses H1, H2 between the microphones l, 2 and the speaker 6 in a learning identification method so as to make the output level of the subtractor 3a zero. Accordingly, houling can be suppressed by means of a pseudo echo generated with the new impulse responses H1, H2. In such a way, houling can be automatically suppressed even if the ambient temperature varies or the positions of the microphones and the speaker moves.

Filed: 1992-02-21
Abstract: PURPOSE:To form an ideal junction surface, by continuously changing the concentration of either one element out of a plurality of elements in a film forming space, and making the concentration have an extremal value at a specified portion in the film forming space. CONSTITUTION:The arrangement of holes formed in the bottom part of a film forming space is characteristic. When an alpha-SiGe film which has the smallest band gap, i.e., the highest Ge content, in the vicinity of a gas discharging vent is to be obtained, exhaust vents are concentrically arranged at the portion corresponding to said film. From gas discharging vents 112a-112d, SiH4 gas and GeH4 gas are made to flow while the flow rates are suitably adjusted, and microwave is introduced into all applicators 110a-110d. When a film is deposited in the above state, the Ge content in the film forming space is made zero, and a film whose band gap is indentical to that of a-Si can be formed. Thereby an ideal junction surface can be formed.

Title: Method for printing using screen and pattern paper used for the same method
Inventor: OGURA KAZUHIKO
IPC: B41C1/14
Filed: 1993-03-07
Abstract: PURPOSE:To obtain a method for printing in which the operating efficiency in printing is improved and the maintenance of a screen is simultaneously facilitated and a pattern paper used in the method for printing. CONSTITUTION:A pattern paper 1 previously divided into a remaining part 6 and an unremaining part 7 divided with discontinuous slits (not shown in the figure) is applied through an ink pushed out of a screen 22 thereto. The unremaining part 7 is then removes from the applied pattern paper to form an ink passage part 8 in the part. A letter or a pattern is printed on a material to be printed with the ink passing through the ink passage part 8 by pushing out the ink from the screen 22. Since preparatory operation to prepare the pattern paper is not required, the letter or pattern can simply be printed at a low cost in a short time by anyone. Even when the remaining part 6 is separated into a usual part 4 and an island part 5 in the printing operation, locating operation between both is not required. After completing the printing operation, the screen 22 can be used for the next printing simply by peeling the remaining part 6 without performing washing operation.

Abstract: PURPOSE:To utilize a natural tree as a bioreactor and efficiently produce modified fats and oils in the presence of biological enzymes by cutting the natural tree crosswise, making fats and oils move from the upper surface and carrying out decomposition and synthesis of fats and oils in the presence of the enzymes in the tree. CONSTITUTION:A living tree such as a Japanese oak rooting in the ground is cut at a position 60cm from the ground and a clay material is put with the height of 1cm along the peripheral part of the cut surface so as to form an oil and fat pool surrounded by the clay material. Fats and oils such as rapeseed oil are poured from the above into the pool and allowed to pass through the inside of the tree so as to be treated with biological enzymes in the tree. After allowing it to stand for 7 day, the tree is cut at a part 30cm from the cut surface by using a handsaw and the cat tree material is cut lengthwise so as to contain the central part. The cut piece is cut into the upper, middle and lower parts and subjected to extraction of the fat and oil component with ether. The extract is concentrated and the oil and fat component is recovered. Thus, the objective modified fats and oils having a changed composition of fatty acids can be produced through decomposition and synthesis in the presence of biological enzymes in the natural tree by using the natural tree as a bioreactor.
