    • Black sintered bodies of aluminum nitride are produced by adding a sintering aid selected from the group consisting of (a) an oxide mixture of calcium oxide and at least one of tungsten oxide and molybdenum oxide, (b) an oxide containing calcium and at least one of tungsten and molybdenum and (c) a mixture of compounds capable of being converted into said oxide mixture (a) or said oxide (b) by sintering to aluminum nitride so that the resulting composition consists essentially of 0.1 to 20 wt. % in the total amount (calculated as oxides of Ca, W and Mo) of the sintering aid and balance aluminum nitride, molding the composition and sintering the molded composition at relatively low temperature. The black sintered bodies thus obtained are especially useful as materials for insulating substrate, heat sink and packaging for semiconductor device due to their high density, good thermal conductivity and superior light-shielding ability.

    • According to one embodiment of the invention, there is provided a telephone system comprises gateways used to convert each other's protocols of IP network and PSTN. One of the gateways selectively serves as a main gateway, and the other gateways serve as slave gateways controlled by main gateway. Each of gateways includes a control channel manager, an operation controller and a determination module. Control channel manager of the main gateway controls speech data individually sent and received by gateways, based on a control signal of a control channel of PSTN. Operation controller controls redundancy switching between the plurality of gateways upon occurrence of a fault. Determination module determines whether the fault is associated with control channel. When the fault is associated with control channel, determination module notifies a slave gateway of message used to activate control channel manager of the slave gateway via IP network.
    • 根据本发明的一个实施例,提供了一种电话系统,包括用于转换彼此的IP网络和PSTN协议的网关。 其中一个网关选择充当主网关,其他网关作为主网关控制的从网关。 每个网关包括控制信道管理器,操作控制器和确定模块。 主网关的控制信道管理器根据PSTN的控制信道的控制信号,控制网关单独发送和接收的语音数据。 操作控制器在出现故障时控制多个网关之间的冗余切换。 确定模块确定故障是否与控制通道相关联。 当故障与控制信道相关时,确定模块通过IP网络向从网关通知用于激活从网关的控制信道管理器的消息。
