Abstract: An exhaust gas purification filter is used so as to support a NOX purification catalyst. The exhaust gas purification filter includes a honeycomb structure portion and a plug portion. The honeycomb structure portion includes a partition wall and cells. Numerous pores are formed in the partition wall. The cells are partitioned by the partition walls and form a flow path for an exhaust gas. The plug portion alternately seals an inflow end surface or an outflow end surface for the exhaust gas in the cells. The partition wall has a gas permeability coefficient that is equal to or greater than 0.35×10?12 m2, a pore volume ratio of pore diameters of 9 ?m or less that is equal to or less than 25%, and an average pore diameter that is equal to or greater than 12 ?m.

Abstract: A honeycomb structure body has a skin part of a cylindrical shape and a honeycomb structural part formed with the skin part together in a monolithic body. The skin part and the honeycomb structural part have partition walls of a porous structure. The cells have first cells arranged adjacent to the skin part and second cells arranged adjacent to the first cells. The skin part, the first cells and the second cells form an outer peripheral section. A central section is arranged inside the outer peripheral section. The honeycomb structure body satisfies a relationship in which a thermal expansion coefficient of the outer peripheral section is greater than a thermal expansion coefficient of the central section.

Abstract: A honeycomb structure body has an outer skin, cells arranged in an inside of the outer skin, and partition walls having pores. The partition walls are arranged in the inside of the outer skin. Each of the cells is surrounded by the partition walls. The pores have communicating pores which communicate with each other adjacent cells. Exhaust gas emitted from an engine passes adjacent cells through the communicating pores. The number of the communicating pores is at a density of not less than 18000 [pores/0.25 mm2] before a catalyst is supported in the pores. An exhaust gas purification filter having the honeycomb structure body with the catalyst is arranged in an exhaust gas pipe to purify exhaust gas containing PM emitted from an engine.

Abstract: An exhaust gas purification filter is provided which has a high capture ratio of particulate matter even when having a high porosity. The exhaust gas purification filter has a case, partition walls and cells. The partition walls are porous, and the interior of the case is partitioned into a plurality of the cells by the partition walls. The partition walls have a plurality of communicating pores which communicate between cells adjacent to respective partition walls. The degree of tortuosity L/T of the communicating pores satisfies L/T?1.1, where T ?m is the thickness of the partition walls and L ?m is the average flow path length of the communicating pores. Furthermore the exhaust gas purification filter is manufactured using porous silica having a tapped bulk density that is no greater than a predetermined value.

Abstract: It is intended to provide a swash plate type continuously variable transmission capable of automatically affording a lock-up state in which second distributing valves are stopped at their stroke mid-point to cut off motor ports when a motor swash plate stands upright, even without using any special interlocking mechanism. Second distributing valves for bringing motor ports of motor cylinder bores into communication with a high-pressure oil path and a low-pressure oil path selectively in an alternate manner are arranged in parallel with the axis X of a cylinder block; a valve swash plate for reciprocating the second distributing valves is integrally combined with a motor swash plate on the same slant plane; and the motor ports are formed so as to be controlled selectively by the second distributing valves at respective positions 90.degree.

Abstract: A friction clutch wherein the distance between a clutch center member on a driven shaft side and a pressure plate, between which an alternate arrangement of clutch friction plates on a driving shaft side and clutch plates on the driven shaft side is disposed, is increased or decreased to disconnect or connect transmission of power between the driving shaft side and the driven shaft side. The driven shaft is constructed so that the clutch center member and the pressure plate are disposed for relative displacement in a direction of rotation. The friction clutch includes a conversion mechanism for converting a relative displacement in the direction of rotation caused by a countertorque inputted to the friction clutch into a relative displacement in a direction of an axis of rotation to increase the distance between the clutch center member and the pressure plate.

Abstract: An operating wire control device for a brake system having an adjust lever rotatable in accordance with the stroke of an inner wire. An adjuster is rotatable by the rotation of the adjust lever and an adjust bolt is movable upon rotation of the adjuster to alter the relative length of the inner wire and an outer wire. The adjust lever comprises a first lever having an abutment member for detecting the stroke of the inner wire and a second lever having a ratchet pawl engaged with a ratchet tooth on a ratchet wheel formed integrally on the adjuster. The second lever is longer than the first lever. An adjust lever spring is provided between the first and second levers, while a return spring extends between the second lever and a housing. The adjust lever spring has a spring force which becomes smaller than that of the return spring when the inner wire has been pulled beyond a prescribed stroke.

Abstract: An automatic adjusting device which is disposed midway of a control wire connecting an actuating mechanism such as a brake and an operating lever. The automatic adjusting device automatically compensates not only the internal wear of the actuating mechanism but also the extension of the control wire so that it can always take up any excessive play or slack of the control wire to thereby impart to the operating lever a minimum play, which corresponds to the proper ineffective stroke of the actuating mechanism.

Abstract: A vehicular brake operating system which comprises a wheel brake, an operating member, a control wire connecting the wheel brake and the operating member and including an outer wire and an inner wire fitted in the former, and an adjusting device disposed midway of the control wire for automatically adjusting a play of the operating member to a proper level in response to the operation of the control wire.
