Abstract: A coating nozzle for high-viscosity paint includes a nozzle slit. The nozzle slit exhibits a specific reduced slit angle, and includes a nozzle-slit outlet, and a nozzle-slit inlet. The nozzle-slit outlet is formed as a distinct substantially-arced shape elongating lopsidedly from the nozzle-slit inlet to the nozzle-slit outlet. The coating nozzle including the nozzle slit can optimize a shear velocity of high-viscosity paint for a discharge rate of the high-viscosity paint in a setting of the actual employment.

Abstract: In a dry friction material and a method for manufacturing the same, to maintain a content of glass fibers low on a whole dry friction material to apply a hole boring for caulking assembly with high strength and high stiffness at a part to be subjected to the hole boring. A part (glass-rich part 30) to be subjected to the hole boring is pressed at a higher pressure than a part not to be subjected to the hole boring in a press-shaping step by providing a rib 21 protruding toward a shaped body side on a part of press dies 20A, 20B corresponding to the part to be subjected to the hole boring. Thereby, only a compounded rubber 4 is pushed outward and only the glass-rich part 30 has an increase in a content of glass fibers 3. Thereby, strength that can withstand the hole boring is obtained. Accordingly, a dry friction material 1 with a bored hole 2 bored without generating a failure in the hole boring can be manufactured.

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: To be able to promote discharge of lubricating oil in a disengaged state while maintaining a large lining area to such an extent that it does not affect torque transmission capacity, heat resistance, and peeling resistance thereby to obtain an excellent effect to reduce a drag torque in a wide range of relative rotation speeds. In a segment friction material 1A as a wet friction material, drag torque reducing grooves 5A are provided only on top surfaces of part of segment pieces 3A among thirty pieces of segment pieces 3, 3A. A series of drag torque reducing grooves 5A extend over five segment pieces 3A along a direction almost at right angles to a straight line connecting a center point 5Aa thereof and a center O of a circumference. The series of drag torque reducing grooves 5A are provided at three places on the circumference. Thereby, discharge of ATF is promoted without reducing a lining area and an oil film is formed on the top surface of the segment piece 3A.

Abstract: A segment-type friction material comprises segment pieces each having a supply passage formed thereon to supply lubricating oil to a surface of each of the segment pieces. The segment-type friction material further comprises oil grooves each having an outer peripheral opening portion extended in a curved shape or a linear shape. Thereby, lubricating oil is sufficiently supplied to the surface of each of the segment pieces from an outer peripheral side thereof or an inner peripheral side thereof and a clearance between the segment-type friction material and its associated separator plate is assured. Moreover, a space for the lubricating oil to flow through an outer periphery is sufficiently assured and a drag torque is reduced.
