  • Patent number: 7970217
    Abstract: A coded bit stream generated on a coding side consists of a VO header, a VOL header, a GOV header, a VOP header and VOP data, and the VOL header multiplexes an object intra-coded indicator signal indicating whether all the VOP data contained in a VOL or GOV are intra coded or not. This enables a decoding side to recognize whether all the VOP data contained in the VOL or GOV in the coded bit stream are intra coded or not by only analyzing the object intra-coded indicator signal. This can facilitate such processings as frame skip control or random access of the VOPs.

  • Patent number: 7965372
    Abstract: A photoresist film removing apparatus includes a reacting chamber, an ozonizer producing a gas supplied to the reacting chamber, and an exhaust system that exhausts the gas from the reacting chamber. A source of a photoresist film-remover is located opposite a stage carrying a substrate covered with photoresist. Photoresist film-remover and the gas are supplied to the substrate through apertures. An electric field may be generated between the source of the photoresist film-remover and the substrate. Alternatively, a centrally located feed tube supplies only one of the gas and the photoresist film-remover through a single aperture and a reservoir discharges the other through apertures. The reservoir surrounds and is sealed to the feed tube. The apparatus may include a container holding a liquid photoresist film-remover and a mixture of the gas and remover is supplied from outside the reacting chamber to the substrate.
