Abstract:
A (semi)grain-finished leather-like sheet composed of an entangled nonwoven fabric of three-dimensionally entangled fiber bundles containing microfine long fibers and an elastic polymer contained in the entangled nonwoven fabric. When dividing the (semi)grain-finished leather-like sheet to five layers with equal thickness, i.e., surface layer, substrate layer 1, substrate layer 2, substrate layer 3 and back layer in this order along the thickness direction, part of the microfine long fibers forming the surface layer and/or the back layer are fuse-bonded to each other and the microfine long fibers forming the intermediate layer are not fuse-bonded. With such a fuse-bonding state of the microfine long fibers, the (semi)grain-finished leather-like sheet combines a low compression resistance and a dense feel each comparable to natural leathers, has a sufficient practical strength, and are excellent in properties which are required according to its use.

A substrate for artificial leathers, comprising a nonwoven fabric body made of microfine fiber bundles and an elastic polymer impregnated therein. The substrate for artificial leathers simultaneously satisfies the following requirements 1 to 4: (1) each of the microfine fiber bundles contains 6 to 150 bundled microfine long fibers in average; (2) a cross-sectional area of the microfine long fibers constituting the microfine fiber bundles is 27 μm2 or less, and 80% or more of the microfine long fibers has a cross-sectional area of from 0.9 to 25 μm2; (3) an average cross-sectional area of the microfine fiber bundles is from 15 to 150 μm2; and (4) on a cross section parallel to a thickness direction of the nonwoven fabric body, cross sections of the microfine fiber bundles exist in a density of from 1000 to 3000/mm2 in average. The raised artificial leathers and grain-finished artificial leathers made from the substrate for artificial leathers are excellent in the properties which are hitherto difficult to be combined.

Abstract:
In a method for manufacturing an electric motor, a cylindrical stator core circumferentially dividable into a plurality of core components is inserted into a circular internal surface of a motor housing. In this case, the motor housing is heated to be expanded thermally thereby enlarge circular internal surface thereof. Then, the stator core is fit over the external surface of an, insertion guide head of a generally cylindrical shape, and the insertion guide head is moved ward toward the thermally expanded motor housing secured on a fixed table to insert the stator re inside the motor housing. When the insertion guide head reaches a predetermined axial position inside the motor housing, a pressing mechanism incorporated in the insertion guide head is operated to press the core components on the circular internal surface of the motor using. Then, the motor housing is contracted as the temperature thereof goes down, whereby the core components are secured such that each of core components is pressed at lateral surfaces thereof against the next core components in the circumferential direction as a result of being pressed by the circular internal surface of the motor housing.
Abstract:
The artificial leather sheet substrates of the invention comprise a united laminate structure of a nonwoven fabric layer A and a knitted or woven fabric layer B and an elastic polymer C impregnated into the united laminate structure. The nonwoven fabric layer A and the knitted or woven fabric layer B are strongly bonded to each other by entanglement. A portion of the microfine fibers constituting the knitted or woven fabric layer B are exposed to the outer surface of the nonwoven fabric layer A. Therefore, the artificial leather sheet substrates exhibit excellent mechanical properties such as resistance to tear stress. Having a high density as compared with conventional artificial leathers, the artificial leather sheet substrates have feel and densified feel similar to those of natural leathers.

An artificial leather including a base layer and a surface layer which is formed on one of surfaces of the base layer. The base layer includes bundles of microfine filaments and an elastic polymer. The surface layer includes the microfine filaments or includes the microfine filaments and the elastic polymer. The surface layer satisfies the relationship of X/Y≥1.5 wherein X is the number of cut ends of the microfine filaments which exist in a region from a surface to a 20 μm depth in a cross section of the artificial leather, Y is the number of cut ends of the microfine filaments which exist in a region from a surface to a 20 μm depth in a cross section perpendicular to the cross section for determining X, and X>Y. The artificial leather having such surface layer exhibits a sufficient gloss without coating a pigment such as metallic powder.
Abstract:
A brake ECU uses a control pressure acquired from a control pressure sensor to determine whether a valve closing operation abnormality or a valve opening operation abnormality occurs in one of a pressure increasing linear control valve and an adjusted flow rate cut valve in a state where a hydraulic pressure is supplied from an accumulator. The brake ECU controls, if the brake ECU determines that an abnormality occurs, respectively the control valve and the cut valve to change to an open state or a closed state, and identifies, based on a change in the control pressure acquired from the control pressure sensor, in which of the control valve and the cut valve the valve opening operation abnormality or the valve closing operation abnormality occurs. The brake ECU can use, after a valve in which the valve opening operation abnormality or the valve closing operation abnormality occurs is identified, a valve in which the abnormality does not occur to carry out brake control.
