摘要： An inverter is configured by double gate TFTs, and an inverter is configured by double gate TFTs. Top gate terminals of the TFTs that configure the inverter are connected to an input terminal DAT(+), and bottom gate terminals are connected to an output of the inverter and an output terminal OUT. Bottom gate terminals of the TFTs that configure the inverter are connected to an input terminal DAT(−), and bottom gate terminals are connected to an output of the inverter. With this, threshold voltages of the inverters are controlled so as to facilitate switching operations of the inverters, and whereby the comparator circuit operates at a high speed. It is possible to obtain a comparator circuit that is insusceptible to a variation in the threshold voltages of the transistors and fluctuation of a common mode voltage of an input signal and capable of operating at a high speed.

摘要： Each of even-numbered photodiodes 1 and 2 for constituting a diode of the present invention (i) has regions (regions 1a through 1c and regions 2a through 2c) whose sizes in a certain direction are identical to sizes of regions of a reference diode 5, and (ii) has a channel width equal to ½ of a channel width W of the reference diode 5. The regions 1a through 1c and the regions 2a through 2c are arranged so as to (i) extend parallel to the certain direction which is provided parallel to a channel length L of the reference diode 5, and so as to be (ii) line-symmetric or point-symmetric to each other as a whole. The photodiodes 1 and 2 are electrically connected to each other in series so as to carry out an equivalent operation to that of the reference diode 5. Employing of the photodiodes 1 and 2 provides a configuration of diodes each having an identical characteristic and occupying a reduced area on a substrate.

摘要： Rules, applied to deny authorization of likely fraudulent transactions, are derived from a modified Patient Rule Induction Method algorithm that uses a target variable and a data set of past transactions each associated with a plurality of input variables and a hyper-rectangle enclosing a multi-dimensional space defined by a representation of the input variable values as points within the multi-dimensional space. While a count of the points within the hyper-rectangle is greater than a minimum support parameter, a first plurality of points proximal to edges of the hyper-rectangle are removed, where each such removing maximizes a mean value of the target variable, and then, while the mean value remains maximized, a second plurality of points proximal to the edges is added, where each adding maximizes or maintains the mean value. The hyper-rectangle is bounded within a minimum bounding box that defines the rules.
