  • Publication number: 20090080066
    Abstract: There is provided a vehicle window glass that can be manufactured at low cost and can efficiently cut off infrared rays impinging on passengers sitting on window seats most susceptible to sunlight exposure, and a manufacturing method for the same. With a glass substrate 1 held by a glass substrate holding member 4 in the vertical direction, a nozzle 2 is used to eject an infrared cutoff liquid 3 onto the upper portion 1b of the glass substrate 1. The infrared cutoff liquid 3 ejected onto the upper portion 1b of the glass substrate 1 flows vertically downward such as to be applied onto the glass substrate 1. The film thickness of the lower portion of an infrared cutoff film is greater than that of the upper portion of the same. The glass substrate 1 is dried for approximately five minutes at room temperature. Then, the glass substrate 1 onto which the infrared cutoff liquid 3 has been applied is placed in an oven preheated to 200° C.

  • Patent number: 7495299
    Abstract: The following steps are carried out: forming a gate electrode on a semiconductor substrate with a gate insulating film interposed therebetween, forming a dummy gate electrode on the semiconductor substrate with a dummy gate insulating film interposed therebetween and forming another dummy gate electrode on the semiconductor substrate with an insulating film for isolation interposed therebetween; forming a metal film on the semiconductor while exposing the gate electrode and covering the dummy gate electrodes; and subjecting the semiconductor substrate to heat treatment and thus siliciding at least an upper part of the gate electrode. Since the gate electrode is silicided and the dummy gate electrodes are non-silicided, this restrains a short circuit from being caused between the gate electrode and adjacent one of the dummy gate electrodes.

  • Publication number: 20090007490
    Abstract: There is provided a vehicle window pane that can be manufactured at low cost and can reduce burning sensation of the skin of a passenger in the vehicle, and a manufacturing method therefor. With a glass plate 1 held by a glass plate holding member 4 in the vertical direction, a nozzle 2 is used to eject infrared cutoff liquid 3 onto the upper portion 1b of the glass plate 1. The infrared cutoff liquid 3 ejected onto the upper portion 1b of the glass plate 1 flows vertically downward, and is applied onto the glass plate 1. The glass plate 1 to which the infrared cutoff liquid 2 has been applied is dried for approximately five minutes at room temperature. Then, the glass plate 1 to which the infrared cutoff liquid 3 has been applied is placed in an oven preheated to 200° C., heated for ten minutes, and then cooled. The glass plate 1 having the infrared cutoff film thereon is thus formed.
