Abstract: An optical film including a first film substrate, and a light diffusion layer that is formed on the first film substrate, wherein the light diffusion layer contains a binder resin and light-diffusing particles, of the light-diffusing particles, 10% or more by number of the light-diffusing particles form an uneven structure on a surface of the light-diffusing layer by the 10% or more of the light-diffusing particles protruding more than a surrounding area not containing any light-diffusing particles, and of the light diffusing particles which cause the binder resin to be protruded and have a protruded portion, 90% or more by number of the protruded portion of light-diffusing particles is covered by the binder resin.

Abstract: The present invention provides a barrier film laminate including a first barrier film that includes a first substrate layer and a first barrier layer formed on the first substrate layer, a second barrier film that includes a second substrate layer and a second barrier layer formed on the substrate layer, and an adhesive layer. In the barrier film laminate, the first barrier film is bonded with the second barrier film so that the first barrier layer faces the second barrier layer with the adhesive layer interposed therebetween. In one embodiment of the barrier film laminate, the adhesive layer is formed of an adhesive containing an epoxy resin, a curing agent having an amino group, and either a silane coupling agent having an epoxy group or a silane coupling agent having an amino group and two hydrolyzable functional groups.

Abstract: An oil pump includes a first spill passage formed on a side surface (60) of a pump chamber (58) to communicate a hydraulic pressure chamber (54) with a first high pressure discharge passage (68) when the entire hydraulic pressure chamber (54) is positioned between the first high pressure discharge passage (68) and a first low pressure discharge passage (70). Therefore, when the hydraulic pressure chamber (54) passes between the first high pressure discharge passage (68) and the first low pressure discharge passage (70), the hydraulic pressure inside the predetermined hydraulic pressure chamber (54) escapes to the first high pressure discharge passage (68) through a first spill passage (76), so a hydraulic pressure value inside the hydraulic pressure chamber (54) is maintained at the pressure value inside the first high pressure discharge passage (68).

Abstract: A vehicular power transmitting system including an oil pump constructed to sufficiently reduce a required drive torque. A high-pressure-port discharge amount of first and second high-pressure passages of the oil pump is determined such that an amount of consumption of working oil of relatively high pressure can be afforded only by the high-pressure-port discharge amount, during steady-state running of a vehicle in which engine speed is not lower than a predetermined threshold value corresponding to a predetermined lowest target input shaft speed of a continuously variable transmission for its shifting control. The pressure of the working oil discharged from first and second low-pressure discharge passages is kept at a predetermined low level, and the required drive torque of the oil pump is sufficiently reduced.

Abstract: A perpendicular magnetic recording medium for use on a magnetic recording/reproducing apparatus which has a magnetic head for recording/reproduction includes a substrate, a magnetic recording layer having a perpendicular magnetic anisotropy, and a soft magnetic under layer interposed between the substrate and the magnetic recording layer. The soft magnetic under layer includes a mechanism for for suppressing motion of the domain walls of the soft magnetic under layer at least with respect to an external magnetic field which is smaller than a stray magnetic field in a vicinity of the magnetic head within the magnetic recording/reproducing apparatus.
