摘要： The present invention discloses a disk drive motor comprising a rotor having an annular space formed therein coaxially with the axis of rotation, and balancing member accommodated in the annular space and capable of changing its mass distribution circumferentially along the circle of the annular space. In case of any imbalanced rotation occurring during the rotation, the balancing member temporarily gather to a portion of the annular space where the mass imbalance is taking place. However, when the motor speed exceeds the value at which resonance takes place due to coincidence between the frequency of the vibration of the balancing member and the natural frequency of the motor, the balancing members move to a position symmetrical with the point of mass imbalance to eliminate the mass imbalance, thereby suppressing the run-out.

摘要： Herein disclosed is a semiconductor memory device, in which peripheral circuits are arranged in a cross area of a semiconductor chip composed of the longitudinal center portions and the transverse center portions, and in which memory arrays are arranged in the four regions which are divided by the cross area. Thanks to this structure in which the peripheral circuits are arranged at the center portion of the chip, the longest signal transmission paths can be shortened to about one half of the chip size to speed up the DRAM which is intended to have a large storage capacity.

摘要： A pair of DRAM chips 1A and 1B are mounted opposedly to each other with wiring means such as lead frames put therebetween, the lead frames being substantially integral with external terminals 3B. Then, these DRAM chips and lead frames are connected together by the conventional wire bonding method. Each chip is bonded with an associated lead frame and each lead frame is disposed as plural lead frame conductors contacting mutually lead frame conductors associated with similarly function bonding pads, i.e. external terminals of the chips, of the other one of the pair of chips. Ones or plural pairs of the thus-connected DRAM chips and lead frames are stacked and corresponding leads of the lead frames are connected in common to form a laminate. The plural DRAM chips thus mounted are activated selectively in accordance with a predetermined chip selection signal. Additionally, partial DRAM chips capable of partially functioning normally are combined together by utilizing the above chip mounting method to constitute a single DRAM package.
