Abstract: Emulsion paint type damping coatings show an excellent film forming property even if it leaves at low temperature from 5 to 20° C. It does not generate a defective coated film like swellings after baking drying and brings out an excellent damping performance within a range of 20 to 60° C. That is, it contains one or more than two kinds of organic chemicals within a range of 0.5% to 5% by weight in total and the MFT, the minimum film forming temperature of the entire resin emulsion is within a range of 5 to 15° C. and the boiling point for a film forming assistant is within a range of 150 to 240° C., thus, it enables to obtain an excellent film forming property at 5° C. and even in baking drying and does not generate a defective coated film like swellings as well. As a result, emulsion paint type damping coatings bring out an excellent damping performance within a range of 20 to 60° C.

Abstract: A segment-type friction material has blocks each composed of four segment pieces. Five blocks are stuck by adhesion to a core metal 2 along an entire circumference thereof so as to constitute one surface of the segment-type friction material. Gaps are provided between the five blocks to form oil grooves that make an automatic transmission fluid (ATF) to flow. Five oil grooves are formed in total on one surface as a whole of the segment-type friction material.

Abstract: A molding apparatus of a wet friction material has a pair of guide posts vertically extending on a molding apparatus main body. The pair of the guide posts passes through fifteen stages (sixteen pieces) of molding dies. A pair of pantograph-type open-close mechanisms is attached to opposite side surfaces of the molding dies. Thus, the molding dies are piled up on each other so as to come near to each other (mold clamping) and move apart from each other (mold opening). With the pantograph-type open-close link mechanism, all the molding dies are opened and closed at the same time. If the molding dies are slid at a speed of 200 mm/sec, it takes only 3.75 seconds (50 mm*15/200 mm=3.75 sec). It takes a double of that time or 7.5 seconds, that is a half of the time of a related art.

Abstract: A friction material has a resin amount distribution that is the largest at a portion near a non-friction surface, that becomes lower toward an inside and that is the lowest at a portion near a friction surface. For example, such friction material is manufacture as follows. First, two friction materials are overlapped while the friction surfaces faced with each other. Then, the friction materials are dried at a room temperature. At this time, the resin has such a characteristic as to move while dragged by a solvent that dries from the non-friction surface located outside. Using such characteristic, the resin amount at the portion near the friction surface is lessened. Then, a temperature at the friction surface is made low and a temperature at the non-friction surface is made high in a drying step of the friction material. Thereby, the resin amount at the portion near the friction surface is lessened.

Abstract: In a wet friction material, to be able to obtain a more significant drag torque reduction effect certainly by making it easy to discharge a lubricating oil which is supplied from an inner peripheral side of a core metal into an outer peripheral side and by preventing a stirred torque from increasing by generating oil retained at an outer periphery, and moreover to be able to obtain a more significant drag torque reduction effect even in case of a specification that there is no lubricating oil supply from the inner peripheral side. In a segment-type friction material 1, it promotes ATF to discharge into outside a diameter and enhances a cavitation by giving R processing to an inner periphery and an outer periphery of segment pieces 3A, 3B so as to shorten an oil groove 4A, and yet it can restrain a stirred torque resulting from forming oil retained by ATF caused by that a space in the outer peripheral side is secured by giving R processing to the outer periphery of segment pieces 3A, 3B.

Abstract: It makes it possible to be able to operate at high velocity and making the square measure of setting small.

Abstract: In a wet friction material, to be able to obtain a more significant drag torque reduction effect certainly even in case of a specification that there is no lubricating oil supply from an inner peripheral side or in case that a stirred torque increases by generating oil retained at an outer periphery. In case of the specification (without axis core lubrication) that there is no lubricating oil (ATF) supply from the inner peripheral side of the wet friction material, that is, in case that there is the lubricating oil supply only from the outer peripheral side, in segment-type friction materials 1, 1A and 1C, by making R processing or chamfering processing to one or both corner portions of the outer periphery of segment pieces 3, 3A, 3B and 3C, it can obtain a significant drag torque reduction effect by a peeling effect that ATF runs from the processing portion into front surfaces of the segment pieces 3, 3A, 3B and 3C and goes into between a counterpart material.

Abstract: In a wet friction material, to be able to reduce a drag torque, while being greater in a disengagement feature and a positive ?-V slope characteristic by keeping a pore diameter large without generating strength reduction or increase in settling quantity. By adding small-particle inorganic filler 2, it attaches the inorganic filler 2 to inter-fiber 3 and it can obtain an effect to improve strength of friction material substrates 1 by connecting the inter-fiber 3 when an impregnated resin is hardened. Moreover, by keeping an absolute specific gravity of the inorganic filler 2, its compounded capacity becomes small and it can secure a pore diameter 5 of the friction material substrates 1 without being filled in pores of the friction material substrates 1 with the inorganic filler 2. As a result, it makes faster to absorb ATF from a friction surface. Therefore, it improves the disengagement feature and the positive ?-V slope characteristic, while reducing the drag torque.

Abstract: In a segment-type wet friction material, an inner peripheral left corner of one segment piece and an inner peripheral right corner of another segment piece are respectively cut off at a fixed angle to a center line of an oil groove. The oil grooves have first oil grooves and second oil grooves. The second oil groove has nearly a uniform width. The first oil groove has an inner peripheral corner portion that is broadened to the center line of the oil groove from a fixed height. In case of being assembled in an automatic transmission, when the segment-type friction material rotates in one direction, an automatic transmission fluid supplied from an inner circumference bumps and touches the portion that is broadened at the fixed angle at a rear side in the rotating direction.

Abstract: In a wet-type friction material, a ring-shaped friction material substrate is compressed and fixed on a surface of a core metal by heat-pressing by a manufacturing metal mold. At the same time, a taper of an angle ? corresponding to a taper at an outer peripheral side of an upper mold is provided on an outer peripheral side of the ring-shaped friction material substrate. Thus, the taper is formed such that a thickness in a radial direction of the ring-shaped friction material substrate becomes smaller from a middle point toward an outer peripheral edge.

Abstract: A wide slit nozzle having a slit as a discharge opening. The thickness of a lateral end part is set smaller than the thickness at a lateral center part. The thickness of the lateral center part is fixed. The thickness of the lateral end part changes linearly from opposite lateral ends of the lateral center part to the opposite lateral ends of the slit. Coating material is discharged from the slit while applied with pressure, so that the coating material is coated while expanded wider than the width of the slit. The coating material is discharged at 7 liter per minute, and a coating width of a first example is 100 mm, for example. A thickness increase of the overlapped part is +25% even when a width or an overlapped margin z of the overlapped part is 10 mm or 20 mm.
