摘要： Embodiments of present invention help to realize a highly reliable magnetic disk drive by preventing a positional displacement between a magnetic head and a target track by decreasing restricting forces that a cover exerts on a base when the temperature is increased. According to one embodiment, a base is formed by aluminum die casting, has a concave, rectangular parallelepiped shape, and is formed with step portions at the four corners. A cover is a flat plate of stainless steel or iron. Four corner portions of the cover are bent to form step portions. The cover is fixed to the base at the four corners with bolts at two side positions (six positions in total). A gasket is inserted at that time to enhance the sealing performance. Since the gasket is a member like a rubber packing, it is necessary to press the gasket with the flat portions of the base and the cover To this end, the gasket is placed on top of the base step portions and the connection between the cover and the base at the four corners is made under the base step portions.
摘要翻译：本发明的实施例有助于通过在温度升高时通过减小盖施加在基座上的限制力来防止磁头和目标轨道之间的位置偏移来实现高度可靠的磁盘驱动。根据一个实施例，基座由铝压铸形成，具有凹形的长方体形状，并且在四个角部形成有台阶部分。盖是不锈钢或铁的平板。盖的四个角部弯曲以形成台阶部。盖子通过两个侧面位置的螺栓（总共六个位置）固定在四个角落的基座上。此时插入垫圈以增强密封性能。由于垫圈是像橡胶垫片的构件，因此需要用基座和盖子的平坦部分按压垫圈。为此，垫圈被放置在基座台阶部分的顶部，盖子和在四个角落处的基部形成在基底台阶部下方。

摘要： Power amplifier circuits which constitute an RF power module used for a digital device capable of handling high frequency signals in two frequency bands are disposed over the same IC chip. The power amplifier circuits are disposed around the IC chip, and a secondary circuit is disposed between the power amplifier circuits. Thus, the power amplifier circuits are provided within the same IC chip to enable a size reduction. Further, the distance between the power amplifier circuits is ensured even if the power amplifier circuits are provided within the same IC chip. It is therefore possible to suppress the coupling between the power amplifier circuits and restrain crosstalk between the power amplifier circuits.
