摘要： PROBLEM TO BE SOLVED: To provide a friction material having high cooling efficiency, solving a problem on a woven cloth that the rate of the depth of a groove to the thickness of the woven cloth is smaller and the flow amount of cooling liquid distributed in a single groove is small, namely, cooling efficiency is poor in the single groove.
SOLUTION: The friction material 11 is annularly punched from the woven cloth W impregnated with a thermosetting resin and hardened by pressing work. The tissue of the cloth W for the friction material having high weaving cooling efficiency is multilayered with three plane-woven tissues W1, W2 and W3. The woven cloth W has threaded weft clearances 12 and threaded warp clearances 13. The weft clearance 12 is formed by lacking wefts Y1, Y2 and Y3. The warp clearance 13 is formed by lacking warps T11, T12, T21, T22, T31 and T32.

摘要： PROBLEM TO BE SOLVED: To provide a three-dimensional woven fabric whose three or more layer weaves are formed of ≤50 denier warps and ≤50 denier wefts and can easily be woven, even when the weave density of the woven fabric is high.
SOLUTION: This three-dimensional woven fabric 11 is formed by binding three weaves 12a, 12b, 12c with binding yarns 13a, 13b. The weaves 12a to 12c are plainly woven from warps 14a to 14c and wefts 15a to 15c, respectively. The binding yarn 13a for binding the first weave 12a and the second weave 12b is penetrated from one side of the adjacent two weaves 12a, 12b and then returned on the other side, and is therefore arranged in both the weaves 12a, 12b to go through the other side. The binding yarn 13b for binding the second weave 12b and the third weave 12c is penetrated from one side of the adjacent two weaves 12b, 12c and then returned on the other side, and is arranged in both the weaves 12b, 12c to go through the other side.

摘要： PROBLEM TO BE SOLVED: To provide a wet type friction material and producing method therefor capable of achieving a high frictional coefficient μ and an improved μ-V positive gradient with the usage of diatomaceous earth as an additive for improving the frictional coefficient μ. SOLUTION: When the diatomaceous earth having a diameter of 1 to 50 μm is added as the additive so as to make paper for the wet type friction material, paste as a chemical showing delayed falling characteristic is added and papermaking is performed. The fine diatomaceous earth hardly sinks, a sinking speed gets slower by the delayed falling characteristic of the paste, and thereby paper is made on which surface the diatomaceous earth is concentrated. The wet type friction material is produced so that the surface becomes a friction surface. A friction examination is performed for thus produced wet type friction material in order to compare with a conventional wet type friction material whereon the diatomaceous earth is evenly dispersed. The friction examination is performed in a condition that a surface pressure is 980 kPa and an oil temperature is 80°. As a result, it is found out that this wet type friction material shows the enhanced friction coefficient μ and the improved μ-V positive gradient compared to the conventional wet type friction material.

摘要： PROBLEM TO BE SOLVED: To ensure a large friction coefficient and high shearing strength using an organic paper-like base material. SOLUTION: This friction material is composed of a paper-like base material formed of fibrous material, a compound binder formed of at least one of metallic alkoxide and organic group substituted metallic alkoxide and impregnated in the base material, and phenol resin impregnated in the base material. Since the compound binder is exposed to the surface of the base material, the frictional property of the compound binder is manifested at the time of friction to increase a boundary friction coefficient. The permeability of the compound binder into the base material is improved by the presence of the phenol resin to obtain high shearing strength. Flexibility is further improved by the presence of the phenol resin compared to the case of having only the compound binder. Compliance to an object member is thereby improved, and the friction coefficient is further improved by the enlargement of contact area.

摘要： PROBLEM TO BE SOLVED: To express a large friction coefficient and ensure a high shear strength by using an organic paper-like base material. SOLUTION: This wet friction material is obtained by impregnating a paper- like base material with an organic-inorganic composite binder in a state compressed in the thickness direction and then thermally treating the impregnation product. The impregnation of the organic-inorganic composite binder permits the expression of a large friction coefficient, and the impregnation of the organic-inorganic composite binder in the state that the paper-like base material is compressed to enhance the density of the fibers further improves the shear strength of the wet friction material.

摘要： PROBLEM TO BE SOLVED: To control the transmitting force arbitrarily without using a mechanical hydraulic mechanism and the like. SOLUTION: The transmitting force is controlled by utilizing that the friction coefficient of the friction surface is changed by giving the electric field to the friction surface of a friction engaging device. The friction engaging members are contacted directly each other by the function of a pushing force so as to friction engaged. When an electric field is given between the friction engaging members, the friction coefficient of the friction surface is changed, and the transmitting force can be changed. This friction engaging device is a clutch device 10, for example. A friction member 20 consisting of an insulation material is installed to an input disk 16, and the friction member 20 is engaged with an output disk 22. The friction surface is being lubricated. A control device 30 controls a voltage applying device 28, to apply the voltage to an electrode 26, and a desired transmitting force is obtained.

摘要： PROBLEM TO BE SOLVED: To improve a coefficient of friction by forming a base layer capable of elastically deforming at the frictional sliding time with a mating material on a support plate, and laminating a frictional surface containing a fiber basic material, filler material and a binder on the base layer. SOLUTION: A friction material is constituted of two layers of a base layer 1 and a friction surface layer 2. The layer 2 is fixed onto a support plate 3 via the base layer 1. The layer 1 has an elastic characteristic and is capable of elastically deforming according to the surface shape of a mating material when frictional sliding is made between it and the mating member. Owing to the elastic deformation of the layer 1, the layer 2 frictionally slides while following the surface shape of the mating material, and thereby the contact area with the mating material is increased, resulting in an increase in a coefficient of friction. In order to provide the layer 1 with an elastic characteristic, for example, the layer 1 is made of a rubber or resin plate or the like having a high elastic material. The layer 1 can also be made of a composite body composed of fibers and fiber entangled elastic fine particles.

摘要： PURPOSE:To obtain a highly durable catalyst for exhaust purification capable of maintaining an early-stage purification capability as it is by arranging the first layer of oxidation catalyst component on a carrier substrate and allowing the second layer consisting of cobalt and zeolite to be carried on the first layer. CONSTITUTION:The first layer 2 of activated alumina 20 on which an oxidation catalyst component such as Pt or Pd 21 is carried is formed on a carrier substrate 1 such as a monolithic carrier substrate or a pellet carrier substrate. Next, the second layer 3 consisting of zeolite 30 and cobalt 31 is formed as a carrier layer on the first layer 2. The catalyst thus obtained is capable of purifying NOx efficiently in an lean and burn atmosphere and also purifying HC and CO. In addition, the catalyst maintains an early-stage purification capability.
