摘要:
A polyimide precursor resin composition comprising (a) a poly(amic acid) containing siloxane linkages, (b) an aminosilane, and (c) a solvent for both the components (a) and (b), can form a polyimide film excellent in adhesiveness and heat resistance and is suitable for producing a semiconductor device having high reliability.
摘要:
A system for collecting a toll for a vehicle, on which a vehicle number plate is mounted, is disclosed. In the system, a radio card as a storage medium is provided in the vehicle. The radio card generates a data signal representing a identification data including a vehicle number data. A radio card access system receives the data signal transmitted from the radio card and processes the data signal to obtain the vehicle number data contained in the radio card. A TV camera picks up an image corresponding to a vehicle number from the number plate of the vehicle. The radio card access system generates vehicle number plate data from the image picked up by the TV camera. The radio card access system compares the vehicle number data and vehicle number plate data and verifies whether or not the two sets of data coincide, the toll of the vehicle is calculated in accordance with the identification data stored in the storage medium.
