Title: Catalytic carrier for purifying exhaust gas and its production
Inventor: SANEKANE YOSHIMARU
IPC: B21D47/00
Filed: 1992-01-28
Abstract: PURPOSE:To improve the strength of a catalytic carrier for purifying exhaust gas so that slippage by the pressure of the exhaust gas passing through the carrier does not occur by forming a flat plate and a corrugated plate in a honeycomb-shaped carrier so that the flat plate and the corrugated plate and a rugged part formed with them are engaged with each other. CONSTITUTION:When the flat plate 1 and the corrugated plate 2 are welded to constitute an integrating plate 5, the rugged parts 9, 10 are formed on the surface of the flat plate and the integrated plate 5 is wound while engaging the rugged part of a succeeding winding layer with the rugged part in a preceding winding layer among both rugged parts 9, 10. Thus, the slippage of the flat plate to the corrugated plate by the high pressure of the exhaust gas flowing to the axial direction of the carrier is prevented, the separation, etc., of the catalyst attached to the carrier is prevented and high purifying function as the purifying device is maintained. Since the carrier is formed by roundly winding the integrated plate made by welding the flat plate with the corrugated plate, the carrier having the structure excellent in strength with the slippage preventing action between the roundly wound layers of the integrated plate by projecting and recessed engaging is obtained.

Title: Ignition timing detector for diesel engine
Inventor: SUZUKI YUTAKA
IPC: F02D41/00
Filed: 1984-02-29
Abstract: PURPOSE:To make the sticking of soot much reducible and, if any, make it possible to be burned off with a combustion flame, by situating the detection surface of an optical detector in a position being more recessed than a combustion chamber where an air-fuel ratio is lean as well as in such a position as being subjected to the direct combustion flame. CONSTITUTION:When an injection pump 16 is driven with a signal out of an electrical control circuit 23, fuel is spouted to a combustion chamber 14 from an injection nozzle 15 and ignited with high pressure, high temperature air by the ascent of a piston 12. At this time, inside the combustion chamber 14, there is relatively rich mixture and soot is liable to be produced but the position of a detecting part 18 of an optical detector 17 is more recessed than the combustion chamber 14 so that this part is relatively lean in mixture, so generation of the soot is little, if any. And, when an engine is warmed up, temperature in the flame subjected to the detecting part 18 goes up, thus the sticking soot can be burned off. With this constitution, accurate and stable ignition timing is detectable for a long period of time.

Title: Image forming material and its manufacture
Inventor: HIRAOKA SABURO
IPC: G03F7/004
Filed: 1999-02-18
Abstract: PROBLEM TO BE SOLVED: To improve a photothermal conversion efficiency, to form a rigid resin image, to enhance adhesive properties of a support to a resin image portion and to improve a plate wear resistance by incorporating a gradient in a film thickness direction of an image forming layer in a containing ratio of a photothermal conversion substance. SOLUTION: A gradient is set in a film thickness direction to a containing ratio of a photothermal conversion substance in an image forming layer so that an emitted light of an image exposure arrives at the innermost side of the layer. Thus, photothermal conversion is efficiently conducted, thermoplastic resin particles are effectively fusion bonded to form a rigid resin image. In the case that the image forming layer exists on a normally grained aluminum support, the substance in the forming layer is increased at its content ratio in the film thickness direction from an air side to a support interface side so that the conversion is sufficiently uniformly spread in the layer with the result that the image becomes tough and the image at the interface side is rigidly adhered, thereby obtaining the lithographic printing plate having excellent plate wear resistance.
