  • Publication number: 20050259068
    Abstract: An image display device has an image display panel, in which two or more groups of particles having different colors and different charge characteristics are sealed between two substrates, at least one of two substrates being transparent, and, in which the particles, to which an electrostatic field produced by a pair of electrodes provided on respective substrates is applied, are made to fly and move so as to display an image. (1) The image display panel has matrix electrodes composed of pairs of electrodes arranged in a matrix manner, a display drive is performed by applying a high potential VH or a low potential VL to respective electrodes constituting the matrix electrodes, and respective electrodes are connected to an intermediate potential V0 between the potentials VH and VL through a small impedance when the potential VH or VL is not applied to respective electrodes.

  • Publication number: 20050052402
    Abstract: A reversible image display panel which comprises a pair of substrates one of which is transparent and a group of particles charged with single polarity, a group of particles with single color charged with single polarity, a group of particles having portions with different colors and different charge characteristics, or two groups of particles with different charge characteristics each enclosed between the substrates, characterized in applying an electric field across the substrates, and displaying images by flying and moving the particles. The reversible image display panel and the image display device in accordance with the invention have fast response speed and simple structure, being superior in stability and vividity. In an occasion of driving, generation of the strong electric field is unnecessary for them and accordingly, electric circuits can be assembled employing general purpose electronic materials.

  • Patent number: 6722970
    Abstract: In a vehicle air conditioner, a blower case for accommodating a blower is connected to an air conditioning case for accommodating an evaporator and the like by a connection duct made of a vibration-absorption material. Therefore, a vibration, transmitted from the blower case to the air conditioning case, can be effectively absorbed by the connection duct, thereby reducing the vibration transmitted from the air conditioning case to a steering wheel unit through a supporting member.

  • Publication number: 20040067525
    Abstract: A method for effectively causing charge-remote fragmentation (CRF) when the structural analysis of an nitrogen-containing organic compound is performed using a high-energy collisional-induced dissociation-mass/mass spectrum (CID-MS/MS spectrum), a reagent to be used in such a method, and a method for analyzing an organic compound by the induction of CRF are provided. The method for the induction of charge-remote fragmentation (CRF) using a high-energy collisional-induced dissociation-mass/mass spectrum (CID-MS/MS spectrum) has the step of: introducing a squaric acid residue into an end of a nitrogen-containing organic compound.
