    • The invention reduces an overhead operation required for re-establishment of a physical signal link. A physical signal link (layer 1 link) is switched over keeping a layer 2 link in the OSI reference model. A database 11 stores information indicating physical signal links and information indicating the maximum length of a layer 2 frame determined according to the ability of physical signal links. When a physical signal link is to be switched over, a target physical signal link is selected and a physical signal link used by the link is switched to the target physical link without releasing the single layer 2 link. The maximum length corresponding to the target physical signal link is obtained from the database 11, and layer 2 frames having the maximum length are transmitted. Switching over a physical signal link is performed in the following manner. When a physical signal link switching-over request is given, establishment of a target physical signal link is required without releasing a layer 2 link, and a multi-reception of control signals using both of the target physical signal link and an original physical signal link is started. After confirming establishment of the target physical signal link, a physical signal link used for transmitting a control signal is switched to the target physical signal link and release of the original physical signal link is required. After confirming release of the original physical signal link, a physical signal link for receiving a control signal is switched to the target physical signal link.
    • 本发明减少了重新建立物理信号链路所需的开销操作。 在OSI参考模型中切换物理信号链路(第1层链路),保持层2链路。 数据库11存储指示物理信号链路的信息和指示根据物理信号链路的能力确定的第2层的最大长度的信息。 当要切换物理信号链路时,选择目标物理信号链路,并且将链路使用的物理信号链路切换到目标物理链路而不释放单层2链路。 从数据库11获得与目标物理信号链路对应的最大长度,发送具有最大长度的层2帧。 以下列方式执行切换物理信号链路。 当给出物理信号链路切换请求时,需要在不释放第2层链路的情况下建立目标物理信号链路,并且使用目标物理信号链路和原始物理信号链路两者的多接收控制信号 开始了 在确认目标物理信号链路的建立之后,将用于发送控制信号的物理信号链路切换到目标物理信号链路,并且需要原始物理信号链路的释放。 在确认原始物理信号链路的释放之后,将用于接收控制信号的物理信号链路切换到目标物理信号链路。

    • A disc grinder includes a grinding wheel cover rotatably mounted to a gear housing about an axis of a spindle. A stopper device can restrict a position adjustable range of the grinding wheel cover of the spindle and includes a first stopper on the side of the grinding wheel cover and a second stopper on the side of the gear housing. The first stopper and the second stopper have stopper surfaces for contacting with each other. An impact absorbing device can absorb an impact produced when the stopper surfaces contact with each other.

    • The invention relates to an optical system which is adapted to form an image having a full 360° (panoramic)-direction angle of view on an image plane or project an image located on an image plane in a full 360° (panoramic)-direction angle of view, and which is of small-format size and has reduced light flare and high resolving power. The optical system comprises a front unit (10) having at least two reflecting surfaces (11, 12), each rotationally symmetric about a center axis (1), and a rear unit (20) that is rotationally symmetric about the center axis and has positive power. The first reflecting surface (11) is located opposite to an entrance pupil (6Y), and the second reflecting surface (12) is located on the same side as the first reflecting surface (11). The entrance pupil (6Y) in a section including the center axis is located between the outer periphery of the first reflecting surface (11) and the outer periphery of the second reflecting surface (12). A light beam coming from afar passes through the front unit (10) and the rear unit (20) in order, forming an image at a position of an image plane (30) off the center axis. The entrance pupil (6Y) is positioned off the center axis in the section including the center axis, and an entrance pupil (6X) is positioned on the center axis in a section that is orthogonal to the section including the center axis. The rear unit (20) is constructed of at least two groups.

    • A storage apparatus according to the present invention can store information related to a power supply abnormality after shutting down the principal functions of a data processing board when a power supply abnormality occurs in a data processing board. A power supply controller of a data processing board mounted in the storage apparatus monitors the operational status of DC/DC power supplies mounted to the data processing board, on the basis of detection signals from a voltage detection circuit. When a power supply abnormality is detected, the power supply controller immediately shuts down the operation of all the DC/DC power supplies. Shutting down the DC/DC power supplies also shuts down the principal functionality of the data processing board. Then, after storing information related to the power supply abnormality in memory, the power supply controller shuts down the auxiliary power supply. The information stored in memory can be transmitted to a management apparatus by way of an intermediary apparatus, which is another data processing board or the like.
