Title: Focus servo controller
Inventor: IIDA MICHIHIKO
IPC: G11B7/085
Filed: 1998-06-10
Abstract: PROBLEM TO BE SOLVED: To stably obtain an appropriate operation even when an objective lens is moved at a high speed to apply a focus search. SOLUTION: In this controller, an objective lens is serchup-moved at a high speed by a search signal of a prescribed level and the speed of the lens movement is reduced by applying a braking signal at the rise of an S character curve of a focus error signal. If the detected objective lens speed is within an appropriate range, a servo loop is closed by the zero cross timing of the curve. If the speed exceeds the appropriate range, the servo loop is closed after applying the braking signal having a larger level for a prescribed time when it passes a prescribed time after the zero cross timing of the S character curve. Furthermore, if the speed is slower than the appropriate range, a switching is conducted again from a first braking signal to a search signal and the servo loop is closed at the zero cross timing of the S character curve.

IPC: H01L21/8246
Filed: 1978-12-28
Abstract: PURPOSE:To minimize the entire semiconductor integrated circuit by integrating a plurality of memories which each incorporates a floating gate and second gate through an n-type source and drain layer surrounding n<+>-type layer and an insulating film on a p-type silicon substrate. CONSTITUTION:p<+>-Type layers 32 and 33, n-type source and drain regions 34, 35 are formed in a p<->-type silicon substrate 31, and a floating gate 37 and second gate 38 are sequentially formed through an insulating film 36 on the substrate. According to this configuration a punch through phenomenon can be completely eliminated by installing the layers 32, 33. An effective channel length becomes sum of the layers 32, 33, which is shorter than the conventional length. In addition, this short channel effect can reduce the threshold voltage Vth and increase the operating margin. Since the respective memories can be thus formed in high performance and reduced area, the entire non-volatile memory thus integrated can remarkably reduce its size.
