  • Patent number: 9950326
    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.

  • Patent number: 9587696
    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.

  • Patent number: 8893644
    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.

  • Patent number: 8765266
    Abstract: A wet friction member contains a pulverized cork heated to 150-200° C. if necessary. The pulverized cork is mixed with other papermaking materials and formed into a paper-made substrate. The paper-made substrate is impregnated with a synthetic resin to be a binder and heated and cured. The cork itself has a high friction coefficient ?. Moreover, a powder thereof increases surface area and area in contact with a separator plate of a counter member, thereby improving a friction coefficient of a friction surface of the wet friction member. The friction coefficient of the cork itself and capacities for absorbing and discharging oil are improved by heating the cork. Thus, there is provided a wet friction member that has a higher friction coefficient ?. An increase in the friction coefficient ?, weight reduction by reducing the number of friction members, and high efficiency are achieved when used as a wet friction member.

  • Patent number: 8727092
    Abstract: A segment-type friction material is composed of segment pieces. An outer circumference of the segment piece is away from an outer circumference of a core plate. A setback amount is about 2 mm. Then, a gap between the outer circumference of the segment piece and an inner peripheral part of an automatic transmission case becomes large. Thus, there is generated a part at which a gap between the segment pieces and a separator plate becomes large in a disengaged state.
