Abstract: A technology that can make the touch detection results at corner portions proper is proposed. A display device includes a display panel, a sensor substrate formed on the display panel, and plural drive electrodes and plural detection electrodes extended in a direction so as to intersect with the plural drive electrodes on the sensor substrate. Among the plural drive electrodes, any of the lengths of N first drive electrodes (where N represents the number), which are continuously adjacent to one another, is shorter than any of the lengths of the other drive electrodes. An area where at least one drive electrode among the N first drive electrodes and at least one detection electrode overlap each other is larger than the area of an intersectional portion where any of the other drive electrodes and any of the other detection electrodes overlap each other.

Abstract: A technology which can improve the accuracy of touch detection is proposed. A display device includes: a touch panel including plural drive electrodes and plural detection electrodes; plural peripheral wirings; and plural switching elements each of which is disposed between a detection electrode and the corresponding peripheral wiring and that is connected to the detection electrode and the corresponding peripheral electrode. The touch panel executes detection by means of a mutual detection scheme using the plural drive electrodes and the plural detection electrodes. In a condition in which a predefined voltage is applied to the peripheral wirings when the plural switching elements are in an off-state, the voltages of the drive electrodes are changed, and subsequently a condition in which the changes of the voltages of the drive electrodes can be detected from the peripheral wirings is set, and the switching elements are turned from off to on.

Abstract: A composite winding type inductor having a stacked-layer structure formed by stacking a plurality of sets of electrically conductive strips for forming plural sets of coils alternately with a plurality of electrically insulting members. The electrically conductive strips in each of the sets are connected to the adjacent ones by way of edges of the electrically insulating members to thereby form a coil. A plurality of the coils thus formed turn around substantially a generally common axis. At least two of the plural sets of the electrically conducting strips are stacked in layers in such a manner as to follow spiral paths in the directions apposite to each other. The coils formed by at least two sets of the electrically conductive strips are connected to each other at least at one of a start end portion, an intermediate portion and a terminal end portion of the coil.

Abstract: An analog-to-digital and digital-to-analog converter includes an array of capacitors each being differently weighed from the others, one electrode of each of the capacitors being connected to a common node. Switches are provided for selectively applying, in response to a first control signal, an analog input applied to an analog input terminal and a plurality of reference voltages to the other electrode of the capacitors. A comparator has a pair of input terminals whose inverting and non-inverting inputs are selectively switched over with respect to polarity in response to a second control signal. The comparator compares a voltage appearing on the node and applied to one of the input terminals and one of the reference voltages applied to the other input terminal. An analog output terminal is connected to the output of the comparator. A successive comparison register sequentially takes in outputs of the comparator in response to a third control signal.

Abstract: In a speech recognition system for effecting substantially linear matching, a start point of an input speech pattern is detected to start counting the frames of the input speech pattern for updating a speech frame number. Each time the speech frame number is updated, a plurality of frame numbers of reference templates are generated in substantially a linear relationship to the frame number, thus providing a plurality of matching paths between each of the reference templates and the input speech pattern. The distance between the input pattern data and the reference template data between the corresponding frames specified by each matching path is calculated each time the speech frame number is updated. An accumulated value of the distances along a matching path from the start point of the input speech until a desired speech frame is regarded as a dissimilarity, and the dissimilarity corresponding to each matching path in each reference template is calculated each time the speech frame is updated.
