Abstract: A microwave continuous heating apparatus is provided with a heating compartment having openings at its front and rear portions and a transfer device which carries a to-be-heated object held thereon through the heating compartment, and microwave electric power is irradiated onto the to-be-heated object that passes through the heating compartment to heat the same. Two microwave absorbing compartments, through which the to-be-heated object passes, are connected to the front and the rear portions of the heating compartment, respectively. A plurality of reflecting plates of metal which are spaced from each other in a forward-and-backward direction are transferred by the transfer device. The object to be heated is placed between two adjacent reflecting plates. The reflecting plates are placed on the transfer device so that at least one reflecting plate is positioned in each microwave absorbing compartment, at least during irradiation of microwaves into the heating compartment.

Abstract: Two electroluminescent substrates, each emitting light having different color, are laminated and bonded together with adhesive layer interposed therebetween. An insulation film such as an epoxy film is placed between two substrates and deformed into an adhesive layer under pressure and heat. The adhesive layer serves as a bonding material and a humidity-protection layer as well. Electrical connection between electrodes of the electroluminescent substrates and outside driving circuits is made at the same time two substrates are bonded by the adhesive layer by bonding wiring sheets together. To further improve the humidity-protection ability of the adhesive layer, the surface of the electroluminescent substrates may be covered by resin which is hardened by radiating ultraviolet light at the same time the insulation film is deformed into the adhesive layer. Thus, the electroluminescent display panel having two substrates can be manufactured in a simple and inexpensive manufacturing process.

Abstract: The invention provides a jet mill which comprises a hollow disk-shaped turning and crushing chamber; a plurality (“m”) of crushing nozzles, to form turning flows by jetting a high pressure gas, in which the jetting ports are inclined to the peripheral wall side and disposed at the sidewall of the turning and crushing chamber; a plurality (“n”) of venturi nozzles, disposed at the side wall of the turning and crushing chamber, which leads materials to be crushed, in line with the high pressure gas; a solid and gas blending chamber which is formed at the upstream side of the venturi nozzles; a crushed material supplying portion communicating with the solid and gas blending chamber; a press-in nozzle disposed in the solid and gas blending chamber coaxially with the venturi nozzles; and an outlet, disposed at the upper part of the middle portion of the turning and crushing chamber, through which micro powder is discharged; wherein the dependency of materials to be crushed for collision with

Abstract: A video display apparatus comprising a memory of fields for plural images, a device for judging whether even-number field or odd-number field, and a frame synchronizing device for reading and selecting fields, in which, if the input has one type of field only, these plural images are displayed simultaneously while keeping correct interlacing.
