摘要:
A rotary anode x-ray tube includes a vacuum vessel in which a cathode, an anode target, a connecting rod, a rotor, bearings, and a heat conducting plate are arranged. The cathode electrode emits electrons. The anode target generates x-rays when electrons emitted from the cathode electrode collide with the target. The connecting rod supports the anode target. The connecting rod is constituted by a rod member consisting of a pulverized sintered material. The rotor is mounted on the connecting rod. The anode target is rotatably supported by the bearings. The heat conducting plate is arranged between the anode target and the rotor. A heat conducting plate made of a material having excellent heat conduction characteristics can be arranged between the anode target and the rotor. The connecting rod is manufactured by processes such as plasticization including tube spinning.

A semiconductor switching apparatus includes a member for radiating heat generated from semiconductor switching element chips and for reducing a thermal stress. The lengths of gate electrode wires are equally set. The semiconductor switching apparatus has a large capacity and good switching characteristics.
摘要:
An ATM cell multiplexing apparatus comprising an AAL multiplexer for generating ATM cells from AAL type-2 user data, a buffer for cells to be sent for temporarily holding the ATM cells generated, and an ATM multiplexer for ATM-multiplexing ATM cells read out from the buffer for cells to be sent is configured. The buffer for cells to be sent comprises functions for discarding an ATM cell when the transmission wait time therefor exceeds a time-over period, and the AAL multiplexer comprises functions for giving priority to user data for which a higher quality of service is demanded than a discarded ATM cell, as the ATM cell to be generated immediately following the discard.
