  • Method for making a curved solar panel for an automobile
    Patent number: 5149351
    Abstract: A method of making a curved glass surface with a solar panel formed thereon. A window for an automobile, especially for a sunroof is formed by heating a glass sheet from 500.degree. to 600.degree. C. A transparent electroconductive film is then formed on one side, such as by a CVD method and bending the sheet with the film after heating the temperature from 580.degree. to 650.degree. C.

  • Gas feeding nozzle for a chemical vapor deposition apparatus
    Patent number: 4880163
    Abstract: A gas feeding nozzle feeds at least one kind of gas to form a thin film on a substrate by a normal pressure vapor deposition process. The nozzle is constituted by a plurality of plate-like bodies. A single or a plurality of slit-like gas discharging apertures are formed by stacking spacers each having at least one cut portion in the gas-discharging direction and partition plates for separating a stream of gas from another stream of gas adjacently flowing. A gas supplying plate with at least one gas supplying opening and at least one groove for flowing the gas in its width direction is attached on at least one of the outermost plate-like bodies.
