A pressure detector has a cylindrical housing projecting into an atmosphere the pressure of which to be measured, a pressure chamber formed within the housing, to which is the pressure to be measured is introduced, a metallic diaphragm formed on a surface of one portion of a wall defining the pressure chamber, which deforms in accordance with changes in the pressure which is to be measured, and a strain gauge provided in the diaphragm for generating an output signal corresponding to the strain generated due to the deformation of the diaphragm. The strain gauge is composed of a diamond monocrystal plate and a diamond semiconductor film formed on the diamond monocrystal plate. On the diamond monocrystal plate are piled a titanium film, a platinum film, and a gold film, in sequence. The gold film is joined to the diaphragm by brazing.

A thin-film electroluminescent device includes dielectric layers having improved dielectric characteristics. The device is fabricated by forming a first transparent electrode layer of ITO, a first dielectric layer, a luminescent layer, a second dielectric layer, and a second transparent electrode layer of ITO in this order on an insulating substrate. Each of the two dielectric layers is a film constituted by TaSnON. That is, the film includes tantalum, tin, oxygen, and nitrogen.

In an electroluminescent element in which a first electrode, a first insulating layer, a luminescent layer, a second insulating layer and a second electrode are sequentially laminated on a substrate, the luminescent layer has a first and second luminescent portions which are located apart from each other. A color filter is provided above one of the first and second luminescent portions. The second electrode includes a first part electrode for activating the first luminescent portion and a second part electrode for activating the second luminescent portion. The color filter is formed so that a portion extending from a bottom face of the color filter is inserted into a gap between the first and second luminescent portions to surround an upper face and side faces of the one of the first and second luminescent portions.

A dry etching method performing dry etching of a material containing zinc forms and patterns a resist on the material to be etched, and etches the material using an etching gas which is a mixed gas of methane gas and an inert gas. A dry etching method that dry etches a material containing zinc etches the material using an etching gas that consists only of methane gas, an inert gas, and hydrogen gas alone. Another dry etching method that dry etches a material containing zinc introduces an etching gas that contains methane gas, an inert gas, and hydrogen gas into a dry etching device, in which the flow rate of the hydrogen gas is set such that it is equal to or greater than the value at which the amount of dissociated hydrogen becomes saturated, and etches the material using the etching gas. An EL element manufacturing method forms a first luminescent material containing zinc in its composition on a first insulated layer, forms a first resist that has a first pattern on the first luminescent material, dry etches the first luminescent material through the first resist, thereby forming the first luminescent layer; forms a second luminescent material having zinc in its composition on the first luminescent layer, forms a second resist on the second luminescent material, and dry etches the second luminescent material through the second resist.

An electroluminescent display panel which is able to selectively display different colors by changing a voltage level imposed thereon is made in a simple structure. A first luminescent layer (4) emitting green light, for example, and a second luminescent layer (5) emitting orange light, for example, are directly laminated on each other without interposing an intermediate electrode therebetween. The second luminescent layer covers only a part of the first luminescent layer to form a single layer portion and a double layer portion. The single layer portion emits green light at a low voltage level, while the double layer portion emits lemon light having a higher luminance at a high voltage level. The display may be made in a form of a matrix or a certain pattern. The display panel may be used as an instrument panel for an automobile. The green light display is used at night time, while the lemon light display with a high luminance is used at day time to cope with sun light.

An EL element having a color filter formed on an upper electrode thereof enables a decrease in the pixel loss or line defects. In the EL element, a lower transparent electrode, first insulating layer, luminescent layer and upper transparent electrode are laminated on a glass substrate. Further, a color filter is formed on the upper transparent electrode. As the color filter there is used a posi-resist having an average molecular weight in a range of from 100 to 50000 or a nega-resist having a polymerization reaction percentage in a range of from 5% to 70%.
摘要:
An electro-luminescent display apparatus which is capable of displaying two kinds of images is disclosed. The apparatus has a front and a rear electro-luminescent unit therein, and the green light emitted from the front unit directly displays the real image which looks close to a viewer while the orange light emitted from the rear unit is reflected by a reflector disposed at the back of the apparatus and displays a virtual image which looks far from the viewer. In order to reflect the light emitted backward from the front unit and the light emitted forward from the rear unit, reflecting electrodes are provided on the rear surface of the front unit or a reflecting film is disposed in the space between the front and the rear units.
