摘要： This invention decreases deformation of a plastic substrate caused by thermal expansion and contraction in an evaporation process of forming a multi-layered film of an ND filter, thus helping prevent wrinkles. The plastic substrate serving as the base of the ND filter is made of a polyimide-based plastic material having a glass transition temperature of 200° C. or more, has a total transmittance of light of 90% or more, and has a haze factor of 0.5% or less. As the multi-layered film, Al2O3 films for reduction of the reflectance and TiOx films for reduction of the transmittance are alternately formed on the substrate.

摘要： A spectral reflectance in the entire visible wavelength range may be decreased to decrease inconveniences in an image such as flare or ghost. A non-reflective periodic layer including a large number of fine uneven periodic structure bodies is formed on a substrate, and a neutral density (“ND”) film is formed on the other surface of the substrate by vacuum deposition, to improve an anti-reflection function. Regarding a beam entering the ND filter, the MgF2 film of the formed ND film suppresses the spectral reflectance at the boundary of the atmosphere and the ND film and at the boundary of the ND film and the substrate. The non-reflective periodic layer decreases the reflectance at the boundary of the substrate and the atmosphere.

摘要： This invention decreases deformation of a plastic substrate caused by thermal expansion and contraction in an evaporation process of forming a multi-layered film of an ND filter, thus arising of wrinkles is prevented. The plastic substrate serving as the base of the ND filter is made of a polyimide-based plastic material having a glass transition temperature of 200° C. or more, and has a total transmittance of light of 90% or more and has a haze factor, which represents the haze of 0.5% or less. As the multi-layered film, Al2O3 films for reduction of the reflectance and TiOx films for reduction of the transmittance are alternately formed on the substrate. An MgF2 film made of a low-refraction material is formed as the uppermost layer to further reduce the reflection. In the evaporation process, even when the temperature of the plastic substrate reaches almost 200° C., the sufficiently high glass transition temperature of the plastic material can suppress arising of wrinkles on that portion of the plastic substrate where the multi-layered film is formed.

摘要： An all terrain vehicle has necessary rigidity despite a split-type body frame being used. A body frame is split into front and rear subframes along a front-to-rear direction of the vehicle, the subframes being detachably linked to each other via bolts. An upper linking section between the subframes is disposed between an engine upper suspension section for suspending an upper portion of an engine unit and an engine rear suspension section for suspending a rear portion of the engine unit.
