    • A conventional machine package faces problems concerned with costs, weight, etc. and also a problem of antinomy that an attempt to enhance the noise reducing performance increases the airflow resistance and then deteriorates the cooling performance. Providing a sound absorbing structure with the heat radiation performance ensured within a practical range and then with considerably improved noise reducing effect achieves a low-noise machine package with a downsized casing and a reduced cooling fan power. There is provided a sound absorbing structure having a plurality of polyester fiber sound absorbing cylinders each formed into a circular-cylindrical shape, formed of a base material of polyester fiber whose surface is combined and covered with polymer nonwoven fabric of polyester fiber or the like, and arranged at a support member in at least either of a suction port and an exhaust port in such a manner that long axes of the sound absorbing cylinders intersect substantially perpendicularly with a flow direction of air flowing through the suction port or the exhaust port. This makes it possible to reduce noise while controlling the airflow resistance minimum, thus achieving downsizing of a cooling fan and reduction of a cooling fan power.
    • 常规的机器包装面临成本,重量等问题,并且还存在着提高降噪性能的尝试增加了气流阻力,从而降低冷却性能的问题。 提供具有散热性能的吸音结构,确保在实用范围内,然后显着改善降噪效果,实现了具有小型外壳的低噪声机器封装和降低的冷却风扇功率。 提供了一种吸音结构,其具有多个聚酯纤维吸音筒,每个聚酯纤维吸音筒形成圆筒形,由表面组合并被聚酯纤维等的聚合物无纺布覆盖的聚酯纤维的基材形成, 并且以这样的方式布置在吸入口和排气口中的至少一个中的支撑构件处,使得吸音缸的长轴与流过吸入口或排气口的空气的流动方向大致垂直地相交。 这使得可以在控制气流阻力最小的同时降低噪声,从而实现冷却风扇的小型化并降低冷却风扇功率。

    • A communication apparatus, which is capable of allowing a plurality of communication systems respectively having different types of communication modes to coexist with one another on a single communication medium, satisfying Qos requirements with the use of only a simple configuration thereof, and minutely setting an exclusive use rate of a medium, is provided. A coexistence signal cycle T 209 is divided into M time periods by a communication slot unit 207 which is constituted of N communication slots. At least one communication slot in the communication slot unit 207 is defined as a “D-Slot” which can obtain a communication right M/X times during the coexistence signal cycle T 209, and remaining communication slots other than the D-Slot in the communication slot unit 207 is defined as “S-Slots” which can obtain the communication right M times during the coexistence signal cycle T 209. A communication band to be used exclusively in one communication system is allocated in a unit of 1/X of the communication slot D-Slot, and also in a unit of one of the communication slots S-Slots.
