A glazing comprises first and second busbars for connection to an electrical supply; a third busbar between the first and second busbars; plural conductors electrically connected to the first busbar; wherein a first group of the conductors extends from the first busbar to the third busbar to form a first resistor; a second group of the conductors extends from a side of the third busbar facing the second busbar and is electrically connected to the second busbar to form a second resistor; fewer conductors extend from the side of the third busbar facing the second busbar than extend from a side of the third busbar facing the first busbar; at least one gap on one side of the third busbar opposite a conductor on the other side and an information acquisition area between the third busbar and the second busbar, the at least one gap being outside the information acquisition area.

The present invention relates to a window glass for vehicle, which includes a glass plate and an antenna provided to the glass plate and capable of receiving electromagnetic waves of AM broadcasting and FM broadcasting, in which the antenna includes an antenna element and a feeding portion electrically connected to the antenna element, the antenna element lies at a distance of longer than 20 mm from a metallic portion of the vehicle in a vehicle-mounted state, the antenna element includes at least one horizontal portion extending in an approximately horizontal direction in the vehicle-mounted state, the horizontal portion has an open end or has a bent portion bending apart therefrom which has an open end, and the horizontal portion has a total element length that is at least 3/4 of an overall length of the antenna element.

Laminated glass includes: a first glass plate having a rectangular shape, and including a first side and a second side opposing the first side; a second glass plate arranged opposing the first glass plate, and having substantially the same shape as the shape of the first glass plate; and an intermediate film arranged between the first glass plate and the second glass plate, the intermediate film including: a first bus bar extending along an end portion closer to the first side; a second bus bar extending along an end portion closer to the second side; and a plurality of heating lines arranged parallel to each other so as to connect the first bus bar and the second bus bar to each other.

A laminated glass according to the present invention is a windshield for an automobile to which an information acquisition device for acquiring information from the outside of a vehicle by emitting and/or receiving light can be installed, the windshield including an outer glass plate that includes a first side and a second side that is opposite to the first side, an inner glass plate that is arranged opposite to the outer glass plate and has substantially the same shape as the outer glass plate, and an intermediate film that is arranged between the outer glass plate and the inner glass plate. The windshield includes an information acquisition region that is to be located opposite to the information acquisition device and through which the light passes.

Laminated glazings with embedded wire circuits, have many uses. But, due to the higher cost of manufacture, they are not widely used. This invention provides a process to reduce the cost of production for embedded wire laminated glazing. Rather than embedding the wire one interlayer at a time, several circuits are produced on the same sheet, cut out and then inserted into the interlayer of each separate laminate during assembly, reducing the direct labor and capital investment required.

A circuit-including film comprising: a resin film (1); and a conductive fine wire circuit (A) and a conductive circuit (B) independent of the conductive fine wire circuit (A), which are arranged on one surface of the resin film (1), wherein the resin film (1) contains at least one resin selected from the group consisting of a polyvinyl acetal resin, an ionomer resin and an ethylene-(vinyl acetate) copolymer resin.

Laminated glass includes: an outer glass plate having a first side and a second side; an inner glass plate that is arranged opposing the outer glass plate and has substantially the same shape as a shape of the outer glass plate; and an intermediate layer arranged between the outer and the inner glass, wherein the intermediate layer has a heat-generating layer including: a first bus bar that extends along an end portion closer to the first side; a second bus bar that extends along an end portion closer to the second side; and a plurality of heating lines arranged so as to connect the first bus bar and the second bus bar to each other, and when a predetermined voltage is applied between the first and second bus bars, an amount of heat generated per unit length of each of the heating lines is 2.0 W/m or less.

A transportation apparatus includes: a window member; a first heating unit arranged to heat a first region of the window member; a second heating unit arranged to heat a second region of the window member; and a control unit configured to control driving of the first heating unit and the second heating unit. The first region and the second region are adjacent regions. The control unit performs first heating control of making a heating output of the first heating unit larger than a heating output of the second heating unit.

A silicone coating is provided for glass and other surfaces with improved glass clarity and maintenance requirements. In addition, a process for preparing a film with improved glass clarity and maintenance requirements. Further a method is provided for adhering an improved coating to a glass (or other) surface. Also a silicone coating is provided for granite, cement, and lexan/plastic.

A polyvinyl acetal resin film for laminated glass, a viscosity of toluene/ethanol=1/1 (by mass ratio) solution of a polyvinyl acetal resin in a resin composition constituting the polyvinyl acetal resin film with a concentration of 10% by mass, measured at 30 rpm and 20° C. by using a Brookfield-type (B-type) viscometer, being more than 200 mPa.Math.s, the polyvinyl acetal resin film comprising a plasticizer in an amount of 0 to 20% by mass based on a total mass of the resin composition constituting the polyvinyl acetal resin film, and the polyvinyl acetal resin film having a thickness of 10 to 350 μm.
