A dispersion-type EL device includes a short-bar contact, a first insulating layer, a back electrode layer, a dielectric layer, a luminescent layer, and an optically transparent electrode layer, which are sequentially formed on a temporary substrate that has been processed with an exfoliation treatment. This configuration realizes a reduction in size in a thickness direction. Furthermore, an illuminated switch unit is provided, in which a dispersion-type EL device peeled off from a temporary substrate and a wiring board having a comb-like contact are connected to each other.
摘要:
A wiring substrate to be used in a variety of electronic apparatuses, and an input device, such as an optically transparent touch panel, using the same wiring substrate, and a method of manufacturing the same input device are disclosed. The invention simplifies a construction of the wiring substrate, reduces the number of manufacturing steps of the substrate, and makes all the connectors of the substrate in a single-sheet structure. The electrical and mechanical connections of those connectors to other connecting means can be thus highly reliable. Plural wiring patterns 22, 23, 24 and 25, and connectors 22A, 23A, 24A and 25A are formed on a first principal surface of wiring substrate 20. Substrate 20 includes flexible bending section P-P, and when substrate 20 is bend along bending section P-P, some connectors such as 24A, 25A are placed on a second principal surface opposite to the first one, so that wiring substrate 20 is formed.

A seat sensor includes a top sheet made of insulating film; an upper insulating layer with insulating particles partially protruding from the surface of the upper insulating layer; and an upper resistor layer formed over the upper insulating layer. The seat sensor further includes a bottom sheet made of insulating resin film disposed under the top sheet; a lower insulating layer with insulating particles partially protruding from the surface of the lower insulating layer; a lower resistor layer formed over the lower insulating layer, and an insulating spacer layer formed between the top sheet and the bottom sheet. The above construction provides a seat sensor that has stable resistance properties even after repeated loading and a detection device using the seat sensor.

摘要:
A set of a transparent electrode layer and a luminescent layer in which phosphor particles are dispersed are formed on a transparent resin film, and this set is formed layer by layer to create more than one luminescent layer. One or more luminescent layers are divided into multiple luminescent color regions. Or, the transparent electrode layer is electrically separated into two or more regions. This configuration enables the display of multiple patterns in multiple luminescent colors using one dispersed EL lamp. Accordingly, the multicolor EL lamp, which is aesthetically appealing as well as good visibility, can be provided for a display unit of a range of electronic equipment and backlight for LCDs.

The present invention has an object to provide a steel for a chimney or a gas duct, which is excellent in pitting resistance and rust adhesion in a corrosive environment caused by combustion waste gas in a plant in which the combustion of natural gas occurs. Pitting resistance and rust adhesion are remarkably improved in the steel of the present invention which steel is prepared by using a 5% Cr steel as the base, while reducing an impurity sulfur to not more than 0.010 wt. %, adding titanium within a range of 0.005 to 0.05 wt. %, and further adding nickel alone within a range of 1.0 to 2.5 wt. %, or adding molybdenum alone within a range of 0.10 to 1.0 wt. %, or adding in combination therewith trace amount of copper or molybdenum within a range of 0.10 to 1.0 wt. %.
摘要:
In ultrasonotomography, ultrasonic transducers are divided in the scanning direction and in a direction (elevation direction) orthogonal to the scanning direction and by changing the aperture in the elevation direction through focus in elevation direction, a tomogram and a Doppler signal of a blood flow can be obtained and displayed two-dimensionally. Doppler data is obtained by effecting slight angle scan of the ultrasonic beam mechanically or electronically in the elevation direction. Data pieces for the same raster of a plurality of Doppler data pieces obtained through the slight angle scan in the elevation direction are added/averaged or added to improve the S/N ration. By effecting the slight angle scan of the ultrasonic beam in the elevation direction orthogonal to a tomogram plane, a vessel at a position deviant form the tomogram plane can be found. Also, by virtue of the variable aperture in elevation direction and the function of focus in elevation direction, the resolution of tomogram in the orthogonal direction can be improved to promote the intensity of signal. In addition, by adding/averaging or adding blood flow signals, the S/N ratio can be improved.
