A press forming method includes: a first forming step of press-forming a preformed part including: a top portion and flange portions having same shapes as a top portion and a flange portions in a target shape of a press-formed product; and side wall portions having projecting chevron shape in a cross-section in a press-forming direction as compared with side wall portions; and a second forming step of press-forming the preformed part into the target shape. Each side wall portions includes: a side wall portion adjacent to top connecting to the top portion; a side wall portion adjacent to flange connecting to the flange; and a bent portion between the side wall portion adjacent to top and the side wall portion adjacent to flange. An angle on an acute side formed by the side wall portion adjacent to top and a horizontal plane decreases toward an end portion from a center.

An aerodynamic noise reduction memberincludes: a plate-like support portionsandwiched between a plurality of finsandof a brake diskand a rotating memberof a railroad vehicle; and a plurality of protruding portionsprotruding from the support portion. Each of the plurality of protruding portionsis provided in such a manner that, in a state in which the support portionis sandwiched between the plurality of finsandand the rotating member, each of the protruding portionspartially occludes between the fastening finand the anchoring finadjacent to each other in a circumferential direction of the brake disk

The wheel is for a railway vehicle that travels on a rail. The wheel includes a wheel tread, a flange and a throat portion. The wheel tread is provided at an outer circumferential portion of the wheel. The wheel tread faces a head surface of the rail. The flange is provided at the outer circumferential portion of the wheel. The flange projects further outward than the wheel tread in the radial direction of the wheel. The throat portion connects the surface of the flange and the wheel tread. The throat portion has a protrusion. The protrusion projects to the rail side. The protrusion extends along the entire circumference of the throat portion.

Wheel for railway vehicle

An amount of wear of a railroad vehicle wheel flange online while traveling in a curved section is directly measured. A laser rangefinderis installed on an outer track side in a rounded curve section of a railroad track. When a railroad vehicle travels through the rounded curve section, the laser rangefindermeasures a distance to a front rim surface of a wheel on an outer track side of a wheelset in a forward direction of travel of a bogie forming a vehicle. The amount of wheel flange wear is obtained by comparing this measured distance with a previous measurement of the measured distance. It is then possible to control the amount of wheel flange wear when traveling in a curved section, thus making it possible to quickly find wheels having flange wear that has exceeded a control range and ensure safety during travel of the railroad vehicle.

Method for measuring wear of railroad vehicle wheel flange

Provided is a shock-absorbing member that does not increase the cost of automobile and that can increase the absorbed energy per unit weight of the shock-absorbing member. A shock-absorbing memberincludes a tubular main body portion, a bent portionthat is formed continuous with the main body portion, and a flangeprovided at the proximal end of the main body portionvia the bent portion. The main body portionis caused to undergo eversion deformation by a shock power acting on the distal end of the main body portionso that shock energy is absorbed. The main body portionhas regular polygonal cross-section orthogonal to the axial direction, and has a tapered shape that an area of the cross-section orthogonal to the axial direction decreases toward the distal end.

Shock-absorbing member

A transparent film, the back-face of which has excellent resistance to scratch and printability, and a surface protection film which has such a transparent film are provided. A transparent filmhas a substrate layerformed of a transparent resin material, and a back-face layerwith a thickness of 1 &#x3bc;m or less provided on a first faceA thereof. A percent change in coefficient of friction &#x394;&#x3bc; is less than 10% for the transparent filmwhen the percent change is determined from a coefficient of friction &#x3bc;of the back-face layer after being conserved at 50&#xb0; C. and 15% RH for three days and a coefficient of friction &#x3bc;of the back-face layer after being conserved at 80&#xb0; C. and 80% RH for three days, with an absolute value of difference between the two coefficients of friction |&#x3bc;&#x2212;&#x3bc;| being divided by the smaller value of the two coefficients of friction.

An electronic apparatus has a first housing, a second housing, and speakers. The first housing and second housing are so coupled as to be movable between a first position away from each other and a second position in which one of them is laid on the other. The speaker is provided in the first housing. A first opening is situated at a place covered over the second housing when it is in the second position and corresponding to the speaker. A second opening is located on the second housing at a place corresponding to the first opening when the second housing is in the second position. A third opening is provided in the second housing situated on the outer side at the second position and communicates with the second opening.
