  • Patent number: 11398364
    Abstract: An electron gun includes a cathode that is heated to emit thermions; a cathode heating power supply that supplies a cathode heating current for heating the cathode; a grid that has a first aperture formed therein and that has a grid voltage applied thereto, the grid voltage having a potential lower than that of the cathode, wherein the grid converges the thermions passing through the first aperture by the grid voltage; an anode that has a second aperture formed therein and that has an anode voltage applied thereto, wherein the anode causes the thermions extracted from the cathode to pass through the second aperture as an electron beam by the anode voltage; an anode-voltage power supply that applies the anode voltage to the anode; and a controller that causes the anode voltage having a positive potential to be applied from the anode-voltage power supply to the anode.

  • Patent number: 11314438
    Abstract: An arithmetic processing device includes an arithmetic circuit and a memory access controller performing access control for a read request on a memory module including a volatile memory and a nonvolatile memory, the volatile memory operating as a cache of the nonvolatile memory. The memory access controller stores an address table on which unit addresses including a request address of the read request are registered, issues a speculative read to the memory module in response to the read request and update the address table when the request address is included in the unit addresses in the address table, and issues a normal read when the request address is not included in any of the unit addresses. When the normal read is issued, read data is received after transmitting a transmission request signal. When the speculative read is issued, read data are acquired when receiving a hit flag.

  • Patent number: 11302370
    Abstract: Data is synchronized when transmitted from a circuit operated at first frequency to another circuit operated at second frequency. A synchronization method includes storing data write pointers in a line, storing data input from a source at first frequency at a location in a data buffer designated by the write pointer at one end of the line, taking out the write pointer at the one end from the line to store it in the synchronization buffer, synchronizing a validation signal input from the input source at first frequency to second frequency, reading out the write pointer stored in the synchronization buffer when the validation signal is synchronized, adding completion information that indicates completion of synchronization to the data stored at the location in the data buffer designated by the read out write pointer, and reading out, from the data buffer, the data to which the completion information is added.

  • Patent number: 9646552
    Abstract: In RGB time division drives, there is capacitor coupling due to the effects of fluctuation in the drain lines, and thus, the image quality deteriorates (lateral smearing), so that the display brightness becomes different from the desired display brightness due to delay in the convergence of the fluctuation of the common potential, and thus, it is a goal to prevent the image quality from deteriorating (lateral smearing). In RGB time division drives, the order of time division is switched for each frame, or in the direction of the horizontal lines.
