Abstract: In an SiP constituted by laminating a plurality of chips, it is an object to reduce a thickness of the SiP without damaging a strength of a chip on an upper side and deteriorating a reliability due to dicing in the case in which the chip on the upper side is larger than a chip on a lower side. A spot facing portion is provided by etching in the vicinity of a center of a bottom face of a chip on an upper side having a circuit formation surface to be a top face, and a chip on a lower side is disposed on an inside of the spot facing portion.

Abstract: A mounting device (30) for mounting a vehicle interior part (20) to a vehicle body 10 includes a first engaging portion (31), a second engaging portion (32), and a movement limiting portion (33). The first engaging portion (31) is engaged and thus fixed to the vehicle body (10) so as to be kept from being disengaged therefrom under a predetermined load. The second engaging portion (32) is engaged and thus fixed to the interior part (20) so as to be disengaged therefrom under the predetermined load. While the second engaging portion (32) is engaged with the interior part (20), the movement limiting portion (33) is kept within an interior space (22) formed in the interior part (20). When the interior part is detached and moves away from the vehicle body (10), the movement limiting portion (33) prevents the interior part (20) from moving away from the vehicle body (10) by a distance exceeding a predetermined value.

Abstract: In a spindle motor utilizing dynamic-pressure bearings having a full-fill structure, a bearing configuration that balances and sustains at or above atmospheric pressure the internal pressure of the bearing oil. Thrust and radial bearing sections are configured within oil-filled bearing clearances in between the rotor, the shaft, and a shaft-encompassing hollow bearing member. A communicating passage one end of which opens on, radially inwardly along, the thrust bearing section is formed in the bearing member. Either axial ends of the bearing clearance in between the bearing member and shaft communicate through the passage. The communicating passage enables the oil to redistribute itself within the bearing clearances. Pressure difference between the axial upper and lower ends of the oil retained in between the bearing member and the shaft is compensated through the communicating passage, preventing incidents of negative pressure within the oil and of over-lift on the rotor.

Abstract: Spindle motor utilizing a dynamic-pressure bearing device having a full-fill structure and capable of discharging air bubbles from the lubricating oil after it is charged into the bearing device, as well as air bubbles appearing in the oil due to cavitation in handling. Thrust and radial bearing sections are configured within bearing clearances in between the rotor, the shaft, and a shaft-encompassing hollow bearing member. A communicating passage enabling the oil to redistribute itself within the bearing clearances is formed in the bearing member. At least one ray-like groove that reaches from the radially inward edge of dynamic-pressure-generating grooves in the thrust bearing section to the rim of the shaft-encompassing hollow is furnished in the bearing member. When the motor rotates the air bubbles are stirred and minced by the ray-like groove, and migrate toward release at the single oil-air interface.
