    • A piston allowing a lubrication layer of a resin coating with a low friction coefficient to be tightly adhered to a skirt portion of a piston for an internal combustion engine, with low friction, superior wear resistance, and superior anti-seizing properties and that can reduce wear of a cylinder inner wall even if the lubrication layer is peeled off or abraded, is provided. Metal or ceramic fine particles having an average particle diameter of 20 μm to 400 μm are injected with compressed air or compressed nitrogen as a mixture fluid onto the skirt portion of the piston, made of an aluminum alloy and produced by a method such as casting or forging, at an injection speed of 80 m/s or more or an injection pressure of 0.2 MPa or more to be collided with the skirt portion, thereby uniformly making a microstructure of a piston base material fine-grained in a depth range of 1 μm to 15 μm from a surface of the skirt portion and forming a modified layer with an activated surface. A lubrication layer is formed on the modified layer, for example, by applying a resin with a low friction coefficient, while a surface of the modified layer is being activated.
    • 允许具有低摩擦系数的树脂涂层的润滑层的活塞紧密地粘附到用于内燃机的活塞的裙部,具有低摩擦,优异的耐磨性和优异的抗咬合性能,并且可以减少 即使润滑层被剥离或磨损,也提供了汽缸内壁的磨损。 将平均粒径为20〜400μm的金属或陶瓷微粒子以压缩空气或压缩氮气作为混合流体注入活塞的裙部,由铝合金制成,并通过铸造或 锻造,以80m / s以上的注射速度或0.2MPa以上的注射压力与裙部碰撞,从而均匀地使在1μm的深度范围内细粒化的活塞基材的微观结构 从裙部的表面到15μm,并且形成具有活化表面的改性层。 在改性层的表面上,例如通过涂布摩擦系数低的树脂,在改性层上形成润滑层。

    • The invention relates to an information processing apparatus and method by which it is made possible to efficiently provide change information of broadcast contents in accordance with the necessity of a user. A server 2 compares contents information acquired from a contents information production apparatus 5 and contents information prior by one generation stored in a contents information database 11. If a result of the comparison proves that the contents information has a change, the contents information is registered with a change code added thereto into a change information database 12. When contents information of broadcast contents corresponding to reservation contents information transmitted from a broadcast receiving and recording apparatus 3-1 is found in the change information database 12, the server 2 transmits change information to the broadcast receiving and recording apparatus 3-1. The invention can be applied to a system which provides contents information through the Internet.
    • 本发明涉及一种能够根据用户的需要高效地提供广播内容的改变信息的信息处理装置和方法。 服务器2比较从内容信息制作装置5获取的内容信息和存储在内容信息数据库11中的一代之前的内容信息。 如果比较的结果证明内容信息具有改变,则将内容信息与添加到其中的改变代码注册到改变信息数据库12中。 当在改变信息数据库12中找到与从广播接收和记录装置3-1发送的预约内容信息相对应的广播内容的内容信息时,服务器2向广播接收和记录装置3-1发送改变信息。 本发明可以应用于通过因特网提供内容信息的系统。
