Title: Method and equipment for dynamic self-bias region of integrated circuit
Inventor: NATAARE AIERO
IPC: H01L21/8222
Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To ensure a timely response when the voltage of an isolated region clamped by a switch is rapidly changed by maintaining the isolated region with a reference potential, and instructing the opening of the switch. SOLUTION: When the potential of a region 1 (SUB) is rapidly dropped to a ground potential by capacity coupling, the potential of an isolated region 2 (ISO) is dragged toward a negative voltage value. The dynamic potential movement of the region 2 is detected by a comparator COMP beyond a reference voltage clamped by a switch T, and the switch T is opened by changing the state. The region 2 is turned into a high impedance state against a floating or ground node according to the opening of the switch T, and as a result, the region potential is turned into a free state by capacitive coupling C1 and C2, and the decreased voltage of the substrate region 1 is tracked by presenting a negative voltage value. Thus, the region 2 can be biased to the potential presented by the substrate region 1, and allowed to stay with a negative potential.

IPC: F16H59/24
Filed: 1990-04-09
Abstract: PURPOSE:To secure the extent of sufficient accelerability at both low speed and high request output ranges of a vehicle by installing a gear ratio regulating means which regulates a transmission gear ratio so as to realize the desired value determined on the basis of request output value and car speed of the vehicle from the stand-point stored in advance. CONSTITUTION:In an electronic controller 90, input signals or the like out of each sensor are read in, and on the basis of these signals, car speed and each revolution of an input shaft 30 and an output shaft 38 are calculated, whereby a gear ratio of a continuously variable transmission CVT14 is calculated at need. Successively, from the standpoint stored in a specified storage area 114 of a read-only memory ROM94 in advance, on the basis of actual throttle opening and car speed, the desired input shaft revolution is calculated. Then, a control deviation between actual revolution and the desired input shaft revolution of the input shaft 30 is calculated, and a shift mode and a duty ratio are determined so as to solve the deviation. Thus, the transmission gear ratio is regulated so as to secure the shift mode and the duty ratio as well as to make the actual input shaft revolution accord with the desired input shaft revolution.

IPC: G01N21/94
Filed: 1989-04-13
Abstract: PURPOSE:To count the number of the defect patterns of an object to be inspected by discriminating the projection angle or corner of the defect pattern of a binary image from four pixel elements extracted from the binary image. CONSTITUTION:From the whole image data during the scanning of a sensor, data of four pixel of (i, j), (i-1, j) (i, j-1) and (i-1, j-1) (i and j satisfy 2 <= i <=m and 2 <= j <= n) in a binary image are inputted. Subsequently, the projection angle or corner of the defect pattern of the binary image is discriminated from the data of four pixel elements. The projection angle is in such a case that one pixel of the inputted four pixels corresponds to the pattern part and the projection corner is in such a case that three pixels among the inputted four pixels correspond to the pattern part. The number of projection angles under a definite condition are more than the number of corners by 1 geometrically. Therefore, the number of projection angles of each pattern is added and the number of corners is subtracted and, when totalization is performed with respect to the whole of the image, the total number of patterns can be calculated.
