A glass plate module according to the present invention is a glass plate module to be attached at a position adjacent to a door of a vehicle that can be opened and closed, and the glass plate module includes a glass plate, a window assembly that is fixed to a peripheral edge of the glass plate, and a molding portion that includes a tubular molding portion main body provided with a through hole extending along the window assembly, and is fixed to the window assembly. The molding portion main body is configured to come into contact with a portion of the closed door.

An object of the present invention is to provide a laminated glass which reduces light transmittance loss of a certain region thereof at a predetermined wavelength, particularly within a near-IR (750 to 1,000 nm) range and which facilitates provision of an optical instrument employing the near-IR light without partial substitution of an intermediate film. The invention provides a laminated glass for vehicle formed of two glass sheets stuck with a thermoplastic resin film, wherein the laminated glass has a first region and a second region; the second region is provided in a belt-like form along upper side of the laminated glass when the laminated glass is secured onto the vehicle; the first region has a visible light transmittance of 70% or higher; the second region has a visible light transmittance of 5% to 50%; the difference, in a light transmittance within a wavelength range of 750 to 1,000 nm, between the first region and the second region is 5% or less; and the second region has a light transmittance of 25% or higher, within a wavelength range of 750 to 1,000 nm.

Laminated glass with shade band

A glass panel has a first sheet glass and a second sheet glass which are disposed so that main surfaces thereof are made to face each other, an interlayer film which joins the first sheet glass and the second sheet glass together and an electronic tag disposed between the first sheet glass and the second sheet glass. A shielding layer which interrupts the transmission of light is formed on the first sheet glass. A side of the electronic tag is colored such that an external color of a location where the electronic tag is disposed is made difficult to be discriminated from the color of the shielding layer when the location is seen through the second sheet glass.

The present invention aims at providing a method for designing a glass-plate-aimed bending mold making use of a 3-dimensional CAD application for solid models, in a short time with simple operations, by utilizing a previously designed solid model. To this end, there is modified a ring frame of a solid model of a mold stored in an existing-solid-model storing part, such that the ring frame conforms to the shape of a new glass plate, by glass shape replacing means. By using modified parameter reflecting means, the modification of the modifiable parameters inherited from the existing solid-model is reflected to the modified solid model, to thereby optimize the modifiable parameters of a new solid model.

When a predetermined region of a light-transmitting platelike member, such as a front windshield, is divided into a plurality of small parts to detect its optical distortion, and a target is sensed in turn through each small part of the region by image sensing means, according to one aspect of this invention, the target has at least three light emitting points capable of representing at least one angle, according to another aspect of this invention, the target represents at least two segments capable of forming at least one predetermined angle, and according to further aspect of this invention, a plurality of unit targets are arrayed in a predetermined direction, the image sensing means is swung along the above predetermined direction, and the platelike member is rotated in a direction across the predetermined direction.

System of detecting optical distortion of a light-transmitting

An automatic drawing apparatus wherein coordinates of dots are determined on the basis of allocation data of unit dot patterns each consisting of one- or two-dimensional dot allocation and data of a reference line obtained by one-dimensionally allotting the unit dot patterns. A dot pattern is plotted on the basis of dot outline data and their coordinate data, thereby producing a high-precision pattern image within a very short period of time.

Apparatus for Automatically drawing a dot pattern

An automated drawing apparatus is disclosed, in which a dot string along a model line of defogging heater wires on a two-dimensional developed view of a glass window of a motor vehicle is digitized to generate functions of two-dimensional free curves corresponding to the heater wires, a width of each conductor of the heater wires is calculated on the basis of input data consisting of a heater resistance, a conductor length, sizes of heating areas, and calorific values of the respective areas, and a basic line of the heater wire is offset by the conductor width to generate conductor contours. Print patterns of heater wires are drawn automatically which eliminates precise manual drafting.
