摘要： The cavity of a plasma jet ignition plug is configured in a stepped shape; i.e., composed of a constricted portion and a diameter-increased portion (65). The inner diameter (B) of the constricted portion is made smaller than the inner diameter (A) of the diameter-increased portion. Further, as measured along the direction of the axis O, the length (Y) of the constricted portion is made equal to or greater than the length (X) of the diameter-increased portion. This configuration suppresses a pressure loss produced when the generated plasma expands within the cavity. As a result, the energy of the plasma at the time of jetting is increased, and the igniting performance for an air-fuel mixture can be improved.

摘要： In transmitting data between a server device and a client device or between communication terminals, a data transfer rate is set in response to an available bandwidth, an application of the data, and the like not to cause waste of the network. A controlling portion detects a packet loss caused per transmission of data, and then chooses a compression mode whose data transfer rate is low when the packet loss is detected. In contrast, the controlling portion counts a time required from the data transmission (a reciprocation delay time) in such a situation that no packet loss is caused, and chooses a compression mode whose data transfer rate is high when the reciprocation delay time is sufficiently small. As the method of choosing the compression mode, for example, the method of switching a codec into another codec or changing a compression ratio being set in the codec may be employed.

摘要翻译： 在服务器设备和客户端设备之间或通信终端之间传输数据时，响应于可用带宽，数据的应用等而设置数据传输速率，不会造成网络浪费。 控制部分检测每次数据传输引起的分组丢失，然后选择当检测到分组丢失时数据传输速率低的压缩模式。 相反，控制部分在不发生分组丢失的情况下对从数据传输所需的时间（往复延迟时间）进行计数，并且当往复延迟时间足够小时选择数据传输速率高的压缩模式 。 作为选择压缩模式的方法，例如，可以采用将编解码器切换到另一编解码器的方法或改变在编解码器中设置的压缩比。

摘要： In a dust removing system, the level of influence of dust sticking to an objective lens of an optical head is detected from either an amount of light emitted from the optical head and reflected from an optical head or from an access time. Three stages of levels with regard to the degree of influence of the dust are set in accordance with such detection value, and a different message for the removal of dust is indicated on a display unit in response to the level of the influence. When the influence is low, a dust removing mechanism is automatically rendered operative to remove the dust. At the first level at which the influence of dust is low, the optical disk in the optical disk device is discharged and cleaning of the objective lens is performed, and an indication is provided on the display unit representing that cleaning is proceeding. When the second stage is detected, the optical disk in the optical disk device is discharged, and a message is indicated on the display unit representing that cleaning of the objective lens should be performed using a cleaning disk. When the third stage is detected, a message is indicated on the display unit representing that cleaning of the objective lens should be performed by manual operation.
