  • Patent number: 10187092
    Abstract: In a digital transmitter, a digital RF signal generation unit executes digital modulation on I and Q signals to convert the I and Q signal into first and second digital RF signals, respectively, with a bit rate which is twice a carrier frequency. A retiming unit delays the first digital RF signal according to a clock signal with a frequency which is 4n times (n is an integer) the carrier frequency to output the delayed first digital RF signal and delays the phase of the second digital RF signal by 90 degrees with respect to an output of the first digital RF signal to output the delayed second digital RF signal. First and second amplifiers amplify the first and second digital RF signals output by the retiming unit, respectively. A combiner combines the amplified first and second digital RF signals to generate one signal sequence.

  • Patent number: 10185495
    Abstract: A first block storage device sharing an object storage device with a second block storage device has: plural kinds of physical devices having different access response performances; and a hierarchical logical disk created by using the storage areas of the physical devices and the storage area of the object storage device. When the access frequency of a logical block stored in a hierarchy one level above a lowest hierarchy falls below a threshold, the first block storage device searches the object storage device for a logical block having the hash of the logical block as a content address. When the search fails, the first block storage device transmits the logical block to the object storage device to change a hierarchy to store the logical block to the lowest hierarchy, whereas when the search succeeds, omits the transmission and changes a hierarchy to store the logical block to the lowest hierarchy.
