Abstract: An amount of wear of a railroad vehicle wheel flange online while traveling in a curved section is directly measured. A laser rangefinder 3 is 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 rangefinder 3 measures 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.

Abstract: 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 member 1 includes a tubular main body portion 3, a bent portion 5 that is formed continuous with the main body portion 3, and a flange 7 provided at the proximal end of the main body portion 3 via the bent portion 5. The main body portion 3 is caused to undergo eversion deformation by a shock power acting on the distal end of the main body portion 3 so that shock energy is absorbed. The main body portion 3 has 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.

Abstract: 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 film 10 has a substrate layer 12 formed of a transparent resin material, and a back-face layer 14 with a thickness of 1 ?m or less provided on a first face 12A thereof. A percent change in coefficient of friction ?? is less than 10% for the transparent film 10 when the percent change is determined from a coefficient of friction ?50 of the back-face layer after being conserved at 50° C. and 15% RH for three days and a coefficient of friction ?80 of the back-face layer after being conserved at 80° C. and 80% RH for three days, with an absolute value of difference between the two coefficients of friction |?80??50| being divided by the smaller value of the two coefficients of friction.

Abstract: A vehicle door handle device includes: an electric part which is received within an internal space formed within a door handle so as to form a gap between the electric part and an inner surface of the door handle; and an elastic member which is fixed to the electric part, and is pressed against the inner surface of the door handle.

Abstract: The present invention provides an O/W emulsion composition which stimulates little when used on the skin, is safe, can be preserved stably over a long period of time and has excellent feel when used by adding 40 wt % or less of a specific oil component relative to the total amount of the composition to partially saponified polyvinyl alcohol of which a degree of saponification is 70 to 96 mol % and a carboxyvinyl polymer and adjusting the pH to 3.5 to 8.5. This can be used in the same form as generally used agents, such as creams, lotions, ointments, gels and sprays.
