  • Publication number: 20090296762
    Abstract: A light emitting apparatus includes a surface emitting laser and a ceramic package. The surface emitting laser has a common electrode on the back surface thereof and is mounted on the ceramic package via the common electrode. The common electrode of the surface emitting laser is electrically connected to a mount portion of the ceramic package. The mount portion is electrically connected to a back-surface electrode on the back surface of the ceramic package. The mount portion is also thermally connected to a back-surface heat-dissipating electrode on the back surface of the ceramic package via a penetrating electrode that penetrates the ceramic package. The surface emitting laser is spaced apart from the penetrating electrode in order to prevent inclination in light-emitted direction. The back-surface heat-dissipating electrode prevents destruction of a soldered portion when the light emitting apparatus is mounted on a substrate by soldering.

  • Patent number: 7451261
    Abstract: Embodiments of the invention improve the cache hit ratio of read data. A hard disk drive (HDD) according to an embodiment of the present invention determines whether the read buffer should be used in its entirety or the partial continuous space should be used to read read-data from the magnetic disk. When the HDD determines use of the partial continuous space, the HDD specifies the sub-buffer which is a continuous space wherein the leading-end position and the trailing-end position are coupled to each other, and executes data writing to the sub-buffer in parallel with data reading from the sub-buffer and transmission thereof to the host. The sub-buffer capacity coincides with the data length of the back data.

  • Publication number: 20070189137
    Abstract: Embodiments in accordance with the present invention provide methods to record, in a rotating disk storage device, a data block in the unit of a logical sector on a recording medium on which a physical sector including a plurality of logical sectors is formatted. Extra addresses are acquired in a buffer to record write data blocks transferred from a host device. Data blocks are read from the recording medium in the unit of a physical sector. A skip read section discards data blocks having the same data blocks as the write data blocks by removing them from the read data blocks, and sends the remaining data blocks to the buffer. The buffer stores the data blocks in the order of recording in a physical sector.

  • Publication number: 20060129716
    Abstract: Embodiments of the invention reduce the host's wait time by controlling buffer for a data storage device. In a hard disk drive (HDD) disclosed herein, after write data from a host is stored in a write buffer, the size of a continuous free space left forward from the end position of the stored write data is detected. If the size is smaller than a criterion size, that is, the size is not large enough to store the next command's write data, the write buffer is searched for a continuous free space not smaller than the criterion size. If a continuous free space not smaller than the criterion size is detected, the HDD sets a write pointer to the continuous free space. This makes it possible to receive the next write data from the host and therefore reduce the host's wait time.

  • Patent number: 7024390
    Abstract: The invention solves the inconvenience that a customer would experience when his/her electronic wallet was lost or broken down. A backup condition testing means tests predefined backup conditions to determine whether to make a backup, when an electronic wallet device communicates with any other device to transfer monetary data. When the backup condition testing means has determined to make a backup, a backup data sending means sends a predetermined set of backup data collected from the electronic wallet device. A backup data management means receives the backup data from the backup data sending means and saves the received data into its backup database. In this way, the proposed system automatically saves backup data of the electronic wallet device when any backup condition is met. This mechanism permits the customer to have an alternative electronic wallet device to be promptly issued when his/her electronic wallet device is lost.
