  • Patent number: 7495712
    Abstract: Disclosed is a television with a disk playback feature, in which the convenience of the slot-in mechanism is preserved and a disk can be unloaded without being damaged by the lid body. A critical point is established on the path of turning of the second point of application of spring force. By the urging force of the torsion spring, the pivoting door can be forced to either open or close the slot, subject to whether or not the second point is beyond the critical point. The slot can be closed positively by the door plate before the second point reaches the critical point. Once the second point goes beyond the critical point, the pivoting door can be swung open without being thrust by the disk. Therefore, resistance during disk unloading is reduced and it can be prevented that a disk is damaged by touching with the door plate.

  • Publication number: 20080138979
    Abstract: After formation of Cu interconnections 46a to 46e each to be embedded in an interconnection groove 40 of a silicon oxide film 39 by CMP and then washing, the surface of each of the silicon oxide film 39 and Cu interconnections 46a to 46e is treated with a reducing plasma (ammonia plasma). Then, without vacuum break, a cap film (silicon nitride film) is formed continuously. This process makes it possible to improve the dielectric breakdown resistance (reliability) of a copper interconnection formed by the damascene method.

  • Publication number: 20080040530
    Abstract: A data processing apparatus contains a first bus connected to a first memory, a first central processing unit (CPU) being accessible to the first memory via the first bus, a first Direct Memory Access (DMA) controller being accessible to the first memory via the first bus, and a monitor circuit connected to the first bus and monitoring addresses transferred on the first bus. The addresses transferred on the first bus are transmitted from the first DMA controller to the first memory via the first bus. The monitor circuit compares the address transferred on the first bus with a preset monitor target address. The CPU acquires the comparison results by the monitor circuit. If the comparison results show an address match, then the CPU accesses the first memory. The CPU can in this way access the first memory at a correct timing.
