摘要： PURPOSE:To provide a ceramic honeycomb structure which attains a high cleaning efficiency when used in cleaning the exhaust gas of an internal combustion engine or the like by forming a plurality of through fluid passages spiral with respect to the axis of the structure. CONSTITUTION:This invention provides for example a honeycomb structure of cordierite A having numerous through holes 1 formed spiral with respect to the axis of a structure which is circular in the circumferential section and square in the section. To build this structure, for example, a cordierite power, water and an organic binder are kneaded and molded by extrusion. Here, immediately after or in the course of the molding, one end of the structure is fastened on a rotatable jig 2. The jig 2 is turned about 45-180 deg. on the axis thereof to entirely twist the structure so that the through hole 1 is made spiral. The use of the structure A thus formed always change the direction in the flow of an exhaust gas passing through the through hole 1 thereby increasing interaction between the wall face of the through hole and the exhaust gas resulting from disturbed flow. Therefore, supporting a catalyst on the wall face of the through hole can improve the catalytic action and the effect of trapping fine carbon particle or the like.

摘要： PURPOSE:To prevent the generation of relative positional movement to vibrations, etc. and even during driving of several piezoelectric plate, and to maintain the stable state of laminating by bending a metallic plate toward the side surfaces of the piezoelectric plates in the bent section of the metallic plate. CONSTITUTION:A laminated type piezoelectric body A is further bent so that both side end sections of the bent sections 11a, 11b of each ribbon-shaped metallic plate 11, 12 are brought into contact with piezoelectric plates 10, thus laminating the piezoelectric plates 10 at stable positions, then resulting in no mutual relative positional movement of the piezoelectric plates 10 even when high-frequency voltage is applied to the laminated type piezoelectric body and the piezoelectric body is driven. Accordingly, trouble such as short circuit among the metallic plates during driving or cracking due to collisions with a casing, etc. of the piezoelectric plates 10 is also eliminated.

摘要： PURPOSE:To obtain a large electric-discharge energy by forming a piezoelectric element into a stepped form having a thick shaft part and a thin shaft part and applying electrodes onto the both edges and the stepped surface of the piezoelectric element, thus permitting the utilization of the longitudinal effect strain of the piezoelectric element and the increase of voltage. CONSTITUTION:A piezoelectric element 2 is formed into stepped form having two parts of a thick shaft part 2A and a thin shaft part 2B. Electrodes are sintered onto the both edges 22 and 23 and the stepped surface 21 of the piezoelectric element 2. A resonance voltage is applied as the primary voltage between the stepped surface 21 and the edge surface on the thick shafts 2A, side and a voltage is generated at the edge surface of the thin shaft side 2B. Electric discharge is performed by supplying the generated voltage into an electric discharge gap. Therefore, the utilization of the longitudinal effect strain of the piezoelectric element and the increase of voltage due to the shape effect are permitted, and a large electric discharge energy is obtained.

摘要： PURPOSE:To reduce the bending stress operated on a disc by dividing an assembly of the disc and an electrode plate into a plurality of subassemblies, and connecting between the subassemblies by a telescopic lead wiring zone. CONSTITUTION:When a voltage is applied to an assembly 24, discs are elongated, and the elongations are integrated toward downside. The lowermost disc 104D nearest to a piston 28 is displaced to displace the piston 28 at the same distance. Since the assembly 24 is, however, composed of four subassemblies 102A-102D, the elongations in the subassemblies are reduced within 1/4 of the entire elongation. Since the nonelongation lead zones 110A-110D, 112A-112D of the adjacent subassemblies are connected by telescopic lead wiring zones 114A-114C, 116A-116C, respectively, the bending stress acted on the lowermost disc 104D decreases to eliminate a crack at the discs.

摘要： PURPOSE:To measure a pressure distribution on the contact surface and secular change thereof accurately by dividing at least one of electrodes into several parts after the formation thereof on both surfaces of a piezo-electric sheet. CONSTITUTION:A number of top electrodes 12 and terminal electrodes 14 are formed on a piezo-electric sheet 11 by an aluminum evaporation and connected with an aluminum leads 15. An undersurface electrode 13 is formed entirely on the undersurface of the sheet 11 by an aluminum evaporation to form an earth side electrode. The assembly is coated entirely with an insulating resin 18. This pressure distribution detector 1 is inserted between members A and B to be measured and terminal electrodes 14 are connected to a scanner 2 with leads 16. Output voltage of the top electrodes 12 corresponding to a contact pressure are computed with an arithmetic circuit 6 via an amplifier 3, an A/D converter 4 and an interface circuit 5 to determine a pressure distribution, which is displayed in three dimensional coordinates sequentially on a CRT display 9 through an interface 7 and a D/A converter 8.

摘要： PURPOSE:To increase the contact surface area with gases and to improve capturing efficiency by using a honeycomb structural body having plural through- holes as a prototype, forming ceramic layers in the through-holes and removing the prototype part. CONSTITUTION:A honeycomb structural body is manufactured of a combustible material prepd. by kneading coal powder, methyl cellulose and water, and the ceramic slurry prepd. by kneading cordierite powder, PVA, water and iron powder is impregnated in such honeycomb structural body. When said body is dried, ceramic layers are formed on both end surfaces, side surfaces and respective through-holes of the honeycomb structural body. When one end surface is covered with a green sheet of ceramics, the sheet is buried in each through- hole of the end surface. Thereafter, the end surface is rubbed until the combustible material exposes. When such body is calcined, the combustible material burns, and the structure consisting of the partition walls 3 of ceramics and the cover parts 4 closed with the green sheet is formed.

摘要： PURPOSE:To obtain good efficiency of carbon collection as well as an almost complete regeneration by allowing a foam filter and a honeycomb filter to work with their best performance as well as to make up for their defects by each other. CONSTITUTION:A foam filter 5 is furnished on the upper flow side of a honeycomb filter 6 in the stream of exhaust gas, in contact with this honeycomb filter 6, and these filters 5, 6 are housed in a stainless container 3 so as to be supported elastically in the radial direction with the aid of a stainless wire-net 4. When the exhaust gas passes through the foam filter 5, fine carbon particles in the range of comparatively larger particle size are collected. Then the exhaust gas flows into the honeycomb filter 6, and when it passes through pores in a partition wall, most of residual carbon particles are collected to assure releasing of an exhaust gas with low content of fine carbon particles.
