  • Publication number: 20100004479
    Abstract: A process for producing a carbonic ester, characterized in that an aromatic monohydroxy compound or an aliphatic monohydroxy compound is subjected to oxidative carbonylation with carbon monoxide and oxygen in the presence of a palladium catalyst using a compound having a carbonate bond as a reaction solvent. A process for producing a polycarbonate, characterized in that an aromatic dihydroxy compound or an aliphatic dihydroxy compound is subjected to oxidative carbonylation with carbon monoxide and oxygen in the presence of a palladium catalyst using a compound having a carbonate bond as a reaction solvent is also described. The carbonic ester can be produced with a higher yield and at a higher reaction rate and, also, a polycarbonate having a higher molecular weight as compared with the conventional method can be produced with a higher yield and at a higher reaction rate.

  • Publication number: 20090102824
    Abstract: In an odd-shaped display whose display area is not rectangular in shape, a defect such as a reduction in the display quality due to the bright line or the like caused by the pixels that are located in a specific portion can be prevented. In an active matrix substrate used as a substrate of such an odd-shaped display in which the distribution area of the pixel electrodes corresponding to the display area has a shape other than rectangular, at least one dummy gate line is formed outside the gate line that is located at the outermost edge on the scanning start side. For peripheral pixels connected to the gate line and the gate line that lies on the scanning end side of the gate line, the gate lines located one row above the respective gate lines are extended on the opposite side of each of the peripheral pixels from the gate line to which the TFT of each of the peripheral pixels is connected. It is preferable that dummy pixels are located on the upper side of the individual peripheral pixels.

  • Patent number: 7438837
    Abstract: A method of producing a solid electrolyte (3, 13) is disclosed wherein solid electrolyte material is prepared having a composition expressed by a formula: (1-x) ZrO2 {xSc2O3 (where x is a number equal to or greater than 0.05 and equal to or less than 0.15), and a spark plasma method is carried out to sinter solid electrolyte material, resulting in a solid electrolyte. Such spark plasma method is executed by applying first compression load, equal to or less that 40 MPa, to solid electrolyte material, to sinter the solid electrolyte material to obtain sintered material, which is then cooled by applying second compression load, less than first compression load, to the sintered material, resulting in a solid electrolyte.

    Abstract: A developer cartridge is constituted to be mounted attachably and detachably in a directional orthogonal to a rotating shaft of a developing unit main body and the developer cartridge has a developer containing portion and a developer recovery portion for recovering used developer from the developing unit. A supply port opens to supply the developer from the developer containing portion and a recovery port opens in the developer recovery portion to recover used and recovered developer. A supplying opening portion is formed in a shutter member at a position corresponding to the supply port and a recovering portion is formed in the shutter member at a position corresponding to the recovery port. The shutter member opens and closes both the supply port and the recovery port.

  • Patent number: 7146124
    Abstract: Provided are a developer cartridge and a developing apparatus using the developer cartridge, the developer cartridge making it possible to set the amount of developers that can be received to be large even when used in a miniaturized developing device and simplify the mechanism for opening/closing a supply outlet of the developer cartridge. As a result, the developer cartridge has no wasted space and thus can be miniaturized. In order to attain the above, the present invention provides a developer cartridge including a developer receiving portion that receives a new developer and has a section formed to have a shape that occupies a substantially entire space that is allocated to the developer cartridge to be attached.

  • Patent number: 7139513
    Abstract: A developing device unit has a developing device unit main body which rotates about a rotary shaft. Plural developing devices are disposed on the developing device unit main body. The developing devices respectively have developing device main bodies, and developing agent cartridges containing four color developing agents are respectively loaded into the developing device main bodies. The developing agent cartridges are attached/detached in a direction substantially tangential to the rotating direction of the developing device unit main body when a grip section is gripped and operated by the operator in the case where the developing agent cartridges are at a location substantially opposite an image carrier with respect to the rotary shaft.
