Filter

An object of the present invention is to provide a filter that makes it possible to suppress the initial pressure loss and, also, to reduce the rising rate of the pressure loss that increases as particulates accumulate; therefore, the pressure loss at the time when a prescribed amount of particulates have been collected becomes lower, and the pressure loss from the viewpoint of the period up to the recovery as a whole also becomes lower. The present invention provides a filter, which is a column shaped filter having a honeycomb structure, including a number of through holes that are placed in parallel with one another in the length direction with wall portion interposed therebetween, wherein the through holes are constituted by two types of through holes, that is, large-capacity through holes having a relatively larger cross-sectional area in the cross section perpendicular to the length direction and small-capacity through holes having a relatively smaller cross-sectional area in the cross section, with the numbers of the two types of through holes being substantially set to the same, the large-capacity through holes are sealed at one end of the filter, while the small-capacity through holes are sealed at the other end of the filter, and supposing that the ratio (a / b) of the total (a) of lengths of wall portion which is shared by one large-capacity through hole and the adjacent large-capacity through hole in the cross section perpendicular to the length direction and the total (b) of lengths of wall portion which is shared by one large-capacity through hole and the adjacent small-capacity through hole in the cross section perpendicular to the length direction is defined as a and that the ratio (A / B) of the area (A) of the cross section of the large-capacity through hole and the area (B) of the cross section of the small-capacity through hole is defined as β, α and β satisfy the relationship represented by the following formula (1): β≧(20 / 9) α2+1 (where 0<α≦1.5 and 1<β≧6)  (1).

Touch-sensing structure for touch panel and touch-sensing method thereof

ActiveUS20110057898A1Touch sense response time thereof can be fasterHigh resolutionInput/output processes for data processingLine segmentTouch panel
In a touch-sensing structure for a touch panel and a touch-sensing method thereof, the touch-sensing structure includes a plurality of first conducting wires paralleled to each other and a first conductor. A terminal of each first conducting wire is electrically coupled to the first conductor, so as to divide the conductor into a plurality of first line segments. The resistance of each first conducting wire is smaller than that of each first line segment. Wherein, when the displaying area of the touch panel receives an external force, a first conducting wire corresponding to the position designated by the external force is electrically coupled to a reference potential.
