摘要： The electrically heated catalytic converter of the present invention has a substrate, for a catalyst, which is formed as a scroll-like cylindrical laminated assembly. The scroll-like cylindrical laminated assembly is formed by laminating a thin corrugated metal sheet and a thin plain metal sheet and winding the laminated metal sheets together around a center electrode. The outermost layer of the laminated assembly is connected to an outer electrode. The corrugated metal sheet has an insulating coating made of an alumina Al2O3, and the plain metal sheet has no insulating coating. Local conductive connections are formed between the thin metal sheets by soldering the thin metal sheets using strips of zirconium solder foils interposed between the layers of the thin metal sheets. Since zirconium has larger reducing capability than aluminum, the alumina in the insulating coating is reduced by zirconium and precipitates at the local conductive connections. Therefore, the plain metal sheet and the corrugated metal sheet are electrically connected at the local conductive connections. The solder foils in the respective layers are arranged in such a manner that a strip of solder foil in one layer overlaps with strips of solder foils in adjoining layers only at its ends, and does not overlap with strips of solder foils in the layers next to the adjoining layers when viewed from the radial direction. Since the solder foils in two adjoining layers overlap only by a small area, electric current flows between the local conductive connections concentrates in the overlapped area when electricity is fed to the electrodes. Therefore, hot spots are formed. The resistances of overall electric paths can be easily adjusted by changing the lengths of the solder strips, i.e., distances between the hot spots. Therefore, the amount of electric current flowing through electric paths can be kept at appropriate level.

摘要： PROBLEM TO BE SOLVED: To reduce thermal stress caused by temperature gradient which generates in the early period of exhaust gas inflow in the radial direction of a honeycomb body in particular and to prevent breakage of a reinforcement joining part by brazing a metallic flat foil and a corrugated foil in the several layers of the outer periphery of the honeycomb body to form reinforcement parts, reinforcing and joining the remainder. SOLUTION: In the outer peripheral face of a honeycomb body 7 and the internal circumferential face side of a metallic outer cylinder 8, the joining part 13 of a metallic corrugated foil 4 and a metallic flat foil 5 is brazed by joining material 11 to form a current path 12. A reinforcement joining part 14 is joined while keeping insulation. Further, in the outer peripheral part of the honeycomb body 7, the interval between the metallic corrugated foil 4 and the metallic flat foil 5 is extensively joined by brazing material 17 in the several layers to form a reinforcement part 16. Therefore, strength larger than thermal stress caused in the outer peripheral part of the honeycomb body 7 is secured in the reinforcement part 16. Breakdown of the reinforcement joining part 14 in the current path region is prevented and the structural durability of an electric heating type metallic catalytic carrier is increased.

摘要： PURPOSE: To improve the durability of an electrically heated metallic catalyst carrier by forming thermal expansion absorbing structure between a center electrode and a honeycomb body and between electrode lead-out material and a metallic outer cylinder. CONSTITUTION: An electrically heated metallic catalyst carrier 2 is formed of a cylindrical metallic foil laminated body (honeycomb body) obtained by superposing corrugated foil on metallic flat foil and winding them around a center electrode 6, a metallic outer cylinder (casing) with the honeycomb body mounted therein, and the like. Cushioning material 17 for relaxing the radial thermal stress of electrode lead-out material 12o is interposed between electrical insulating material holding the electrode lead-out material 12o, and a locking body 16. A reinforcing joint part 7a with a non-joint part 7o is formed at least at the exhaust gas inflow side end part of the inner peripheral part of the honeycomb body jointed to the center electrode 6 so as to relax the radial thermal stress caused by the thermal expansion difference between the center electrode 6 and the honeycomb body. The durability of the electrically heated metallic catalyst carrier can thereby be improved.

摘要： PURPOSE: To quickly raise the temperature of a catalyst within a short time without applying large current by forming an insulating layer from a first metal oxide and using a solder material foil containing a second metal having higher reductive function than the first metal in a catalyst apparatus which is an electrically heated type and has a layer structure of foils having the insulating layer between the foils. CONSTITUTION: A metal foil layered body 2 to compose a catalyst carrier is produced by layering a flat foil 10 and a corrugated foil 20, joining each edge part to a center electrode 3, and then coiling these foils on the center electrode 3. At this time, a solder material foil 41 containing a metal having higher reductive function than a metal oxide to compose an insulating layer of the corrugated foil 20 is set in a part to compose an electrically conductive joining part between the flat foil 10 and the corrugated foil 20 in the way only parts of the solder material foil in neighboring layers are overlapped in the metal foils-layered direction and then the flat foil 10 and the corrugated foil 20 are coiled. Then, the resultant layered body is heated, so that joining parts in which insulating property of the insulating layer is broken are formed in these parts. An exhaust gas purifying catalyst is carried on the surfaces of the flat foil 10 and the corrugated foil 20.

摘要： PURPOSE:To reduce the production cost of a metallic carrier by inserting a honeycomb body which is alternately wound and superposed with corrugated foil and flat foil on each other and has the corrugated foil on its outermost periphery into a metallic outside cylinder and joining the inside of this honeycomb body and the outside cylinder by a binder. CONSTITUTION:The cylindrical honeycomb body 1 is produced by superposing and spirally winding the corrugated foil 3 having the peak parts of waveforms exhibiting a pseudo sinusoidal waveform and the flat foil 3. The outer periphery of such honeycomb body is composed of the corrugated foil 2. Such honeycomb body is press fitted into the outside cylinder 4. The peak parts of the waveforms of the corrugated foil 2 are formed to a shape having a curvature of radius R=0.2 to 0.6m. Namely, the press fitting of the honeycomb body 1 at a wide press fitting margin is possible at the time of press fitting the honeycomb body into the outside cylinder 4 if the radius of curvature R is in this range. Next, the ends of the honeycomb body 1 are made flush and are brought into contact with sponge impregnated with a binder liquid to simultaneously supply the binders necessary for joining the outside cylinder 4 and the honeycomb body 1 and joining the honeycomb body 1 itself. Powder solder is sprayed by a solder spraying device to the outside cylinder 4 and the honeycomb body 1 which are then subjected to vacuum brazing treatment.

摘要： PURPOSE:To improve productivity and eliminate low yield due to cutting by controlling outside diameter or outside peripheral length completely so as to be within a prescribed target. CONSTITUTION:The tail end of a wavy foil 2 is detected at a prescribed position in the course of winding, and the outside peripheral dimension of a honeycomb structure 3 is measure at the time of detection. Based on a difference between the target value and the measured value of the outside peripheral dimension, the subsequent winding tension of a flat foil 1 is controlled. It is desirable that the winding tension should be controlled by detecting the tail end at plural prescribed positions.
