摘要:
A process for the preparation of graphite-clad nuclear fuel rods comprising coating fine particles of a nuclear fuel such as uranium oxide or thorium oxide with a matrix material containing graphite powder and a binder to form matrix material-coated globules, charging the thus-formed globules, without or after being pre-molded into a green rod-like fuel compact, into the rubber mold of a rubber press molding machine, charging a similar matrix material in the gap between the globules or rod-like fuel compact and the inner wall of the rubber mold, compressing the whole mass in the direction from the side face of the whole mass to the axis thereof to form a green, graphite coat material-coated fuel compact, baking the thus-formed green fuel compact at a temperature of up to 1800.degree. C and, if desired, impregnating the baked product with a resin followed by being rebaked at a temperature of up to 1800.degree. C; and the graphite-clad nuclear fuel rods.

摘要:
An electroluminescent panel comprising a pair of electrodes having sandwiched therebetween a multi-layer comprising an insulating layer in contact with one of said electrodes, an electroluminescent layer and an intermediate layer formed from a conductive material which is in intimate contact with the electroluminescent layer but is out of contact with both of the electrodes. Due to the provision of the intermediate layer, the brightness of the electroluminescent panel can be kept high for a long time.
摘要:
In a liquid crystal display device in which a plurality of liquid crystal layers are stacked on a substrate, a method for bonding a film for sealing liquid crystal to supporting members is improved and the fabrication cost is thereby reduced, in order to provide a reflective type liquid crystal display device that achieves a bright display image and causes no parallax problem, and to provide a reducing method of the device. The liquid crystal display device comprises a substrate, a resin film, a multiplicity of columnar supporting members, an adhesive layer, and a liquid crystal layer. The substrate comprises a pixel electrode and a driving element connected to the pixel electrode, both formed on the upper surface of the substrate. The resin film comprises a common electrode provided on the upper surface of the film, and is disposed upwardly with respect to the substrate. The supporting members are provided on the substrate so as to support the resin film. The adhesive layer is provided between each of the supporting members and the resin film so as to bond the resin film to each of the supporting members. The liquid crystal layer is produced by filling liquid crystal between the substrate and the resin film. The adhesive layer is composed of a thermoplastic material, and characterized in that a bonding state of the resin film and the supporting members is realized by making the adhesive layer have a thermoplastic characteristic.
摘要:
A fuel injector to be mounted on a branch of an engine intake manifold has a hollow body with an injection orifice therein and a valve member mounted slidably in the body and having a pintle extending from one end of the valve member and slidably received in and extending through the injection orifice. A sleeve member is mounted on the body to cover the injection orifice and defines a pintle-receiving space into which the forward end of the pintle extends. Communication apertures are formed in the outer end of the sleeve member to communicate the pintle receiving space with an engine intake passage. The total of the cross-sectional areas of the communication apertures is smaller than the cross-sectional area of the pintle-receiving space.

摘要:
A liquid crystal display device having a pixel electrode, a counter electrode, and a liquid crystal between the electrodes. Liquid crystal molecules in contact or near the respective opposed surfaces of the electrodes have specified pretilt angles as a result of the conditioning of those surfaces. When no voltage is applied, the liquid crystal is in a splay alignment state; applying voltage prior to image display causes a transition of transformation of the splay alignment state to a bend alignment state; image display is carried out under the bend alignment state. Transition from the splay alignment state to the bend alignment state is promoted by having a large pretilt angle domain formed on at least one of the electrode surfaces causing a larger pretilt angle of liquid crystal molecules than is present in a region surrounding the large pretilt angle domain.
