Title: D/a converter
Inventor: SHIMURA HIDEYOSHI
IPC: H01L27/04
Filed: 1991-10-11
Abstract: PURPOSE:To prevent an analog characteristic from being degraded by mutual interference by composing a digital logic part, L-channel side-D/A conversion part and R-channel side-D/A conversion part of a twin-tab CMOS process on the silicone substrate of low concentration. CONSTITUTION:At the D/A converter composed of the twin-tab CMOS process on the silicone substrate (pi substrate) of low concentration, a power source potential wiring and the pi substrate are not connected through an n<+> dispersed layer and therefore, the noise of a power supply potential is not transmitted to the pi substrate. Thus, even when a digital logic part 13, L channel side D/A conversion part 16a and R channel side D/A conversion part 16b are constituted on the same silicone substrate, the analog characteristic is not degraded by the mutual interference between respective blocks.

IPC: H02K3/28
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To enable a magnetic recording apparatus to be thinner by setting a second storage part storing a around layer part of which the number of layers is more than that of a first wound layer among a second coil part at a medium- driving motor frame. SOLUTION: A first coil part 8a which is thinned in the height direction by winding a copper wire in two layers is stored in a first storage part 18b. A third layer 8b3 and a fourth layer 8b4 having the copper wire wound in four layers to compensate for a torque insufficiency at the first coil part 8a are inserted in a second storage part 18c, and moreover, the third, fourth layers 8b3, 8b4 on the side of a stator cover 14 are stored in a storage part 15 on the side of the cover. Accordingly, the distance F between an external bottom face 18d of a frame 18 and a surface 14a of the stator cover 14 can be reduced approximately by thicknesses of the third layer 8b3 and fourth layer 8b4. A magnetic recording apparatus can thinned. For instance, when the copper wire of a diameter of 0.3 mm is used to form a coil part 8, a step I becomes approximately 0.5 mm, which contributes to the thinning.
