Abstract: According to one embodiment, an X-ray tube includes a cathode, an anode, a cathode hood, a first X-ray transmission window, an envelope, and a first restraining member. A second side surface of the first restraining member has a contact surface that is pressed against an inner wall surface in a first hole of the cathode hood. The first X-ray transmission window is maintained in a state of being restrained to an overlap space of a first bottom surface in the first hole by the first restraining member.

Abstract: According to one embodiment, an X-ray tube includes a vacuum enclosure that maintains a vacuum inside, a cathode provided in the vacuum enclosure, which emits an electron beam, an anode target provided in the vacuum enclosure, which emits an X-ray when the electron beam emitted from the cathode enters a focal plane of the anode target, and an X-ray radiation window that allows the X-ray emitted from the focal plane of the anode target to pass therethrough, and the X-ray radiation window comprises a window member and a support for the window member, the vacuum enclosure includes a joint portion formed thereon to be joined to the support and protrude toward an outer side of the vacuum enclosure, and the support comprises a covering portion that covers an inner circumferential surface of the joint portion.

Abstract: According to one embodiment, an X-ray tube, including a cathode including a filament including a leg portion extending from a coil to a distal portion and including a corner portion at the distal portion, a support terminal including a gap, and including an opening portion in which the gap is opened and a bottom portion located on a side opposite to the opening portion, and a cathode cup being connected to the support terminal, the distal portion being located in the gap, the support terminal including a protruding portion protruding in the gap, being located more closely to the bottom portion side than the distal portion, and being joined to the corner portion of the leg portion.

Abstract: According to one embodiment, a stationary anode X-ray tube includes a cathode, an anode, an anode hood, an X-ray transmissive window and a vacuum envelope. A target surface of the anode is an inclined surface disposed to be spaced further away from the cathode towards a first direction. An angle made with respect to a second direction as the first direction is pivoted clockwise or counter-clockwise is any degree but 0°.

Abstract: A data transmission system may have a sending apparatus that sends streaming data, and a receiving apparatus that receives the streaming data and transmits a request of switch of the streaming data to the sending apparatus, in which the sending apparatus may switch the streaming data in response to the received request. The receiving apparatus may include a receiving section, a storage section that stores the streaming data temporarily and transfers it, an operation-detecting section that detects whether a user operates the request, and a control section that controls a transfer rate of the streaming data stored in the storage section to fast-forward the streaming data when the operation-detecting section detects that the user's operation. The sending apparatus may include an information-adding section that adds to the streaming data additional information on the user's operation when receiving a notice of user's operation, and a sending section that sends the additional-information-added streaming data.

Abstract: A system and method of audio/video streaming in which a server transmits over a network an audio/video stream to a client device. The client device is able to send command data to the server causing the server to provide a change in content of the audio/video stream from a first content to a second content. Buffers in the server and client device can be flushed or skipped-over at the time of sending the command data so as to improve response time and marker data can be sent from the server to the client device to indicate the start of the second content.
