Abstract: In order to enhance stability of a discharge lamp at the time of dimming lighting even in the case where a light output is lowered, a direct current superimposing circuit superimposes a direct current voltage on an alternating current voltage applied to a fluorescent lamp, and a dimming signal correction circuit receives a detection value of a direct current voltage detection circuit and a dimming signal that is from an outside, outputs a dimming signal higher in level than the dimming signal in the case where the detection value of the direct current voltage detection circuit exceeds a first threshold value, and decreases the level of the outputted dimming signal to the level of the inputted dimming signal in the case where the detection value of the direct current voltage detection circuit falls down below a second threshold value that is equal to or less than the first threshold value.

Abstract: This invention provides a cord fastener wherein a tightening cord is threaded through or an end of the tightening cord is nipped thereby, the cord fastener being captured and fixed easily with stability on the surface of a down jacket with hood and the like. This cord fastener comprises a cylindrical main body having a bottom and a pair of cam faces at a bottom thereof and a sliding body capable of fitting in an inside of the main body and containing a body portion provided at an upper portion thereof and a pair of elastic leg portions at a lower portion thereof. Insertion holes for a tightening cord are provided in the main body and sliding body. The sliding body is inserted into the main body and then the tightening cord is inserted while pressing the sliding body. When the pressing is released, the sliding body is resiled so that the tightening cord is fixed. A surface fastener member is provided on a surface of the main-body perpendicular to the insertion hole by integral molding or bonding.

Abstract: A data processor and a data processing method are capable of effectively carrying out antialiasing on a plurality of lines that are close to each other or cross each other. The apparatus has a memory for storing a bitmap of a line to be displayed on a display, and a data generator for generating, according to antialiasing conditions, data of every pixel to be plotted to form the line. The data includes an address to specify the pixel and one of intensity and color values to be assigned as a new value to the pixel. The apparatus also has a reader for reading, as an old value, one of intensity and color values that corresponds to the new value and has already been assigned to the pixel, out of the memory at the address of the pixel, and a comparator for comparing the new value with the old value, and only when the new value is greater than the old one, providing a write signal. Only when the write signal is provided, the new value is written into the memory at the address of the pixel.
