Title: Optical tracking abnormality detection system and optical information recording/reproducing device
Inventor: KIMURA MASAHIKO
IPC: H01L31/12
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To surely detect off-tracking by detecting tracking abnormality with the OR of three conditions when a tracking direction moving speed of an objective lens exceeds a prescribed value, when a tracking sum signal is changed to a light quantity increase side by a prescribed amount and when this sum signal is changed to a decrease side by a prescribed value or below. SOLUTION: A position signal is read by a position sensor 38 through an A/D converter 8, and its moving speed (v) is calculated. When this doesn't exceed the prescribed value, the A/D converter 8 reads in the tracking sum signal (a) added with photodetectors 42a, 42c outputs of a tracking control signal from an adder 5 to calculate a threshold value (x). Since the sum signal (a) is a light quantity sum of reflection light of a medium surface emitted by light beam spots S1, S3, since a signal change occurs by a reflectance change on the medium surface, the moving average value of the sum signal (a) according to this change is calculated, and an out decision amount is added, and the threshold value (x) is obtained. Then, when the sum signal (a) is the threshold value (x) or above, it is processed as off-tracking detection.

Title: Logic circuit
Inventor: MUTO SHINICHIRO
IPC: H01L27/088
Filed: 1996-07-17
Abstract: PROBLEM TO BE SOLVED: To provide the leakage reduction performance, to improve the operating speed performance at active time, to suppress the increase in the cost and to improve reliability even if threshold voltage is set to be similar to that of a transistor by connecting the power terminal of a logic gate to a power line through a control transistor. SOLUTION: When a logic gate LGA is active, the potential of a power control signal terminal SL is set to be the potential of a lower potential-side power line VSS and the power control transistor Qs is conducted. Thus, a pseudo power line VDDV becomes the power line and the logic gate operates. When a substrate terminal Np is set to the potential of the power line VDD, the potential difference of PN junction between the substrate of Qs and a source is zero. Thus, the threshold voltage of Qs is low as it is. Consequently, leak reduction performance can be obtained even if the threshold voltage of Qs is set to be similar to the threshold voltage of the transistor constituting LGA. Thus, speed performance when LGA is active improves, the increase in the cost can be suppressed and reliability improves.
