Methods of making a laminated glazing having reduced optical distortion when installed in a vehicle are described. The laminated glazing has first and second sheets of glazing material each separately shaped between a pair of shaping members that are then laminated together. The position for bending the first sheet of glazing material may be deliberately offset from the position for bending the second sheet of glazing material. During the lamination step, the first sheet of glazing material may be displaced relative to the second sheet of glazing material by a lateral and/or longitudinal positional displacement. The first and/or second sheet of glazing material may have been cut such that after lamination at least a portion of the peripheral edges thereof are aligned. Apparatus for shaping a sheet of glazing material for carrying out the aforementioned methods is also described, as is a resulting laminated glazing.

The film can be used in a laminate.

The present invention relates to a cushion flooring material and a manufacturing method for the same and, more particularly, to a cushion flooring material and a manufacturing method for the same, which uses an elastic layer including a PHA resin alone or a composite resin including a PHA resin as a surface layer constituting the cushion flooring material to prevent toxic substances exposed to the user even if the surface layer is exposed due to wear of a surface treatment layer positioned on the surface layer, thereby making the cushion flooring material non-toxic, eco-friendly and excellent in sound insulation.

There is provided a laminated glass for vehicle including a suspended particle device film excellent in property of switching transmittance of light for a long term by suppressing deterioration over time of the suspended particle device film, in particular, deterioration due to intrusion of moisture at an end portion. A laminated glass for vehicle includes: a pair of glass plates opposing each other; a pair of intermediate bonding layers in contact with opposing surfaces of the pair of glass plates respectively; a suspended particle device film arranged in a predetermined region in a region corresponding to a region except at least a part of band-shaped regions of peripheral edge portions of a main surface of the glass plate, between the pair of intermediate bonding layers; and a barrier layer arranged in the band-shaped regions between the pair of intermediate bonding layers and having predetermined adhesiveness and predetermined moisture permeability.

The present invention provides a laminated glass to be used in a windshield of an automobile, and the laminated glass includes: an outer glass sheet; an inner glass sheet arranged opposite to the outer glass sheet, the inner glass sheet having a smaller thickness than that of the outer glass sheet; and an interlayer sandwiched between the outer glass sheet and the inner glass sheet. The interlayer includes at least a core layer and a pair of outer layers between which the core layer is sandwiched, the outer layers having a higher rigidity than that of the core layer. An attachment angle to the vertical with respect to the automobile is 45 degrees or more. The core layer has a Young's modulus of 1 to 25 MPa at a frequency of 100 Hz and a temperature of 20° C.

It is now possible to economically produce, in series production, automotive glazing that has complex small radii feature lines (30). Such feature lines (30) are desirable as they can improve the stiffness of the glazing as well as contribute to the overall aesthetic and differentiation of the vehicle, allowing body lines to blend into and continue in the glazing. However, traditional automotive laminating methods do not lend themselves well to this type of product. Typically, the offset between the mating surfaces of the laminate must be very uniform. Such uniformity is difficult to achieve when producing small radii features. Rather than bending multiple layers with small radii feature lines that can be nested and subsequently laminated using standard plastic automotive interlayers, the invention makes use of a two part method for laminating, a dry lamination process and a wet lamination process, which requires only that the feature lines (30) be present in the outer glass layer (201).

A hurricane-resistant laminated pane comprises a first sheet of thermally strengthened glass having a thickness in the range of from 2 to 24 mm, a second sheet of chemically tempered glass having a thickness in the range of from 0.3 to 1 mm and a surface compression of at least 100 MPa, and a polymer interlayer adhered between the first sheet and the second sheet. A process for making such a pane and a window comprising such a pane are also disclosed.

An interlayer film for laminated glass of the present invention comprises at least an absorption region in which a skin absorption energy rate (X1) of a laminated glass is 25% or less, provided that the laminated glass is produced using two clear glass plates having a solar transmittance of 87.3% based on JIS R 3106.

A laminated glazing used as a head-up display screen includes two sheets of glass and a viscoelastic plastic interlayer arranged between the sheets of glass.

A resonant frequency f.sub.2 of the second resonance mode of a laminated glazing bar with a surface area of 25 mm×300 mm composed of two glass sheets each 2.1 mm thick, between which is incorporated the interlayer, determined by measuring the mechanical impedance (MIM) at 20° C. according to standard ISO 16940, is between 760 Hz and 1000 Hz and the loss factor η.sub.2 of the second resonance mode of the same bar, determined by MIM under the same conditions, is greater than or equal to 0.25.
