摘要： A dispersion-type electroluminescence element composed of a plurality of light-transmitting electrode layers 12A, 12B and a plurality of luminescence layers 13A, 13B of dielectric resin having a high permittivity dispersed with fluorescent powder stacked one layer after the other over the whole region, or in a certain specific region, of one surface of a light-transmitting insulation film 1; and a back electrode layer 14 provided on the last layer of the luminescence layers formed by a printing process. The electroluminescence element is capable of producing a multiple number of luminescence colors, yet the cost is low. In other example of carrying out the present invention, a luminescence layer 23 formed of a luminous body of one single luminescence color provided over a whole region of a surface is sandwiched by a back electrode layer 25 and a light-transmitting electrode layer 22 composed of two groups of fine line comb-teeth layer coupled one tooth after the one of the other electrode layer, and a stripe-shaped color conversion layer 27 is provided in a location corresponding to one of the two groups of comb-teeth fine lines. When an AC voltage is applied on the back electrode layer 25 and each of the two respective light-transmitting electrode layers 22 independently, a multiple number of luminescence colors are produced in a homogeneous plane luminescence, without accompanying the stripes outstanding to the eyes.

摘要： On an upper surface of an insulating transparent film, a transparent electrode layer, a phosphor layer, a dielectric layer, a back-surface electrode, collecting electrode layers, and an insulating coat layer are successively accumulated in predetermined patterns by repeating screen printing operations. Meanwhile, a light-permeable reflection layer containing pearly pigment is formed on a lower surface of the insulating transparent film in a predetermined pattern by a printing operation. With this arrangement, it becomes possible to eliminate the color difference of the light-emitting surface of the EL lighting element between its turned-on and turned-off conditions.

摘要： A filter circuit includes two parallel digital filters, a DAC, and an LPF. The DAC includes two parallel decoders, a parallel-to-serial converter, a switch driver, and a switch. A PLL circuit supplies a reference clock to the DAC. A frequency divider provided in the DAC divides the frequency of the reference clock by two, and supplies the half frequency clock to a parallel processing section (the two decoders and the parallel-to-serial converter) of the DAC and the two digital filters. This makes it easy to secure a timing margin, permitting use in high-speed communication on the order of several GHz.

摘要： In a current steering D/A converter, a 1LSB current source 1 and a 2LSB current source 2 are binary code current sources for outputting currents with current values weighted by ½, and a 4LSB current source 3 is one of a large number of current sources designed as thermometer code current source with the same structure. In first circuits A1, A2 and A4 for respectively determining constant current values of the current sources 1 through 3, a plurality of MOS transistors with a channel length L3 and a channel width W3 are cascode-connected to one another with gate terminals thereof shared. In second circuits B1, B2 and B4 respectively used for setting high output impedance of the current sources 1 through 3, a plurality of MOS transistors with a channel length L4 and a channel width W4 are cascode-connected to one another with gate terminals thereof shared. Accordingly, the current characteristics of the current sources can be made more uniform while reducing their circuit areas, resulting in improving the linearity of the D/A conversion characteristic.
