    • Embodiments of the present invention provide a magnetic disk drive in which the error correction capability of ECC is improved without sacrificing the storage capacity. In one embodiment, a data track adopts a format structure in which no data-to-data gap area is formed in data sectors. When one of the data sectors is updated in a state in which the rotational speed of a magnetic disk does not satisfy specified conditions, a leading end area of a succeeding data sector or a trailing end area of a preceding data sector is overwritten by the data sector. If a read error occurs in the overwritten data sector, ERP steps are executed to perform read retry so that the read error is recovered by means of on-the-fly ECC or erasure correction. In the case of the erasure correction, an erasure pointer equivalent to the maximum number of overwritten bytes is set.

    • A host device is connected to at least one printer through a network. Before printing, the host device broadcasts a query on the network, selects a printer that replies to the query, and sends printer setting information to the printer. The printer includes a setting switch that can be set to different states to accept or reject the printer setting information. A printer replies to the query only if its setting switch is set to the state that accepts the printer setting information. The setting switch avoids the generation of unnecessary replies and thereby simplifies the selection of the printer, as well as protecting the printer from unwanted alteration of its settings.
    • 主机设备通过网络连接至至少一台打印机。 在打印之前,主机设备在网络上广播查询,选择回复查询的打印机,并向打印机发送打印机设置信息。 打印机包括一个设置开关,可以设置为不同的状态来接受或拒绝打印机设置信息。 只有打印机的设置开关设置为接受打印机设置信息的状态,打印机才会回复查询。 设置开关避免了不必要的回复的产生,从而简化了打印机的选择,以及保护打印机免受其设置的不必要的改变。

    • Embodiments of the invention provide a magnetic disk drive capable of reducing an area used for a preamble of each data sector to increase the storage capacity. The magnetic disk drive adopts a data-surface servo system. In one embodiment, main preambles are written on a magnetic disk at a frequency of a data clock. Each of data sectors is written with a write clock that is synchronized with a signal obtained by reading the main preamble. The data sectors include sub preambles respectively. When the data sector which has been written in this manner is read, a read clock is synchronized by use of a signal obtained by reading the main preamble, and a signal obtained by reading the sub preamble included in a data sector to be read. The bit length of the sub preamble is shorter than that of the conventional preamble that is used to independently achieve the synchronization. Accordingly, an area whose length is calculated by summing the bit length of the main preamble and that of the sub preamble becomes smaller than an area whose length is calculated by summing the bit length of the conventional preambles.
    • 本发明的实施例提供一种磁盘驱动器,其能够减少用于每个数据扇区的前导码的区域以增加存储容量。 磁盘驱动器采用数据表面伺服系统。 在一个实施例中,以数据时钟的频率将主要前导码写入磁盘。 写入每个数据扇区的写入时钟与通过读取主前导码获得的信号同步。 数据扇区分别包括子前导码。 当读取以这种方式写入的数据扇区时,通过使用通过读取主前导码获得的信号和通过读取包括在要读取的数据扇区中的子前导码而获得的信号来同步读取时钟。 子前导码的比特长度比用于独立地实现同步的常规前导码的比特长度短。 因此,通过将主前同步码的比特长度和子前导码的比特长度相加来计算长度的区域比通过对常规前导码比特长度求和来计算长度的区域小。

    • In a panel washing device for conveying a panel on a surface plate using an endless belt, spraying washing liquid from a wash nozzle, and washing and removing foreign substances from a surface of the panel by a washing head, a wash nozzle and water discharge path are disposed on a rear end part of a surface plate in a conveying direction of the panel in order to wash and remove the portion of the foreign substances removed from the surface of the panel that has accumulated on an inner surface of the endless belt. Accordingly, the foreign substances accumulated on the endless belt for conveying the panel are washed away and removed, and can be discharged to an exterior of the washing machine.
