  • Patent number: 9345043
    Abstract: A radio communication device includes a memory, a processor coupled to the memory and configured to allocate data to be transmitted from a communication terminal, to a plurality of radio carriers for communication with the communication terminal, identify, when a total amount of the data allocated to the radio carriers exceeds a certain amount, a communication terminal that performs transmission of excess data, which corresponds to the difference between the total amount and the certain amount, using the radio carrier to which the excess data is allocated, and a radio communication device configured to transmit a repeat request to the identified communication terminal that the excess data is transmitted to the radio communication device again.

  • Patent number: 7952773
    Abstract: An image formation device is provided with an image formation section, an image acquisition section, a paper supply cassette and a support body. The image formation section forms images at a recording medium and is supported at a base surface. The image acquisition section is disposed at an upper side of the image formation section. The paper supply cassette is disposed at a lower side of the image formation section and can be drawn out to a near side. The support body supports the image acquisition section at the base surface and forms a cassette cavity which is capable of accommodating a far side of the paper supply cassette.

  • Publication number: 20100294651
    Abstract: A method for manufacturing a gray-tone mask that decreases the wavelength dependency with respect to an exposure wavelength under stable and simple film formation conditions. A reactive sputtering method that sputters a pure Cr target in an atmosphere of Ar and NO is used to form a Cr nitride film having a single-layer structure. Based on a plurality of different spectral transmittance curves obtained under a plurality of film formation conditions having different NO concentrations, a target concentration (intermediate value) for NO is obtained that sets the transmittance uniformity of the semi-transparent film to 1.0% or less in the range of 365 nm to 436 nm or 4.0% or less in the range of 300 nm to 500 nm. Then, a semi-transparent film is formed by using the NO target concentration.
