摘要:
Embodiments of the present invention help improve the process for updating parities accompanied by the writing process. According to one embodiment, a host controller transmits a write command and new data to a hard disk drive (HDD). The HDD reads old data at a region where the new data are to be written. The HDD then XORs the new data and the old data to generate a pseudo-parity. The HDD sets the pseudo-parity in a data frame addressed to both of a horizontal parity disk drive HDD and a diagonal parity disk drive HDD and transmits it. The horizontal parity disk drive HDD and the diagonal parity disk drive HDD update the parities using the pseudo-parity.

An apparatus for holding a printing medium on a rotary drum, includes a rotary drum, a suction device, a medium holding mechanism and a medium removing device. The drum has a recess at its outer surface to extend along its rotation center line and rotates at a predetermined speed. A region of the outer surface, which is adjacent to a rearward end of the recess along the rotation direction, is smaller in the diameter than the remaining of the outer surface. The suction device holds by suction the medium onto the outer surface. The holding mechanism has a hook in the recess and selectively drives the hook between close and open positions. At the close position, the hook is placed over the adjacent region while being prevented from radially outwardly projecting from the remaining of the outer surface, and at the open position it is distanced from the adjacent region. When the medium arrives at the adjacent region, its leading end is held by the hook shifted from the open position to the close position and cooperated with the adjacent region and, when the drum rotates a specific number, the hook is returned to the open position. The removing device removes the medium from the outer surface when the drum rotates the specific number and the hook has moved from the close position to the open position.

A tape loading mechanism is designed for an apparatus operating on a magnetic tape at least partially in a tape cassette and including a rotary drum. In the tape loading mechanism, first tape guides move to draw a portion of the magnetic tape from the tape cassette. In addition, second tape guides move to wrap the magnetic-tape portion, which is drawn from the tape casette, in a helix around the rotary drum. The first tape guides and the second tape guides cooperate with each other to hold substantially constant a length of the magnetic-tape portion which is drawn from the tape cassette.

The present invention is intended to provide an electron-beam-pumped light source capable of irradiating one surface of a semiconductor light-emitting device uniformly with an electron beam, and capable of obtaining a high light output without increasing an accelerating voltage of the electron beam and, in addition, capable of efficiently cooling the semiconductor light-emitting device. An electron-beam-pumped light source of the present invention includes: an electron beam source and a semiconductor light-emitting device excited by an electron beam emitted from the electron beam source, and characterized in that the electron beam source includes a planar electron beam emitting portion and arranged in the periphery of the semiconductor light-emitting device, and light exits from a surface through which the electron beam from the electron beam source of the semiconductor light-emitting device enters.

摘要:
A compact image karaoke device with only a small number of image disks which provides the impression of having a great many background images. Two players are provided for reading background images from image disks. Background images are selected from at least one image unit group corresponding to at least one image genre corresponding to selected song genre and are read by the two players and changed at random, for example, every 30 seconds. By editing the display of background images in this manner, a great number of background image series can be obtained for combinations of the background images. Images obtained and displayed corresponding particularly to the starting portion of the song are provided only on the number of images available. Therefore, even if a great number of songs are consecutively selected, a user will not feel as though the same images are being repeatedly shown.
