  • Publication number: 20010024198
    Abstract: There is provided a flat panel type display apparatus which is superior in heat radiation, withstand voltage characteristic, and the like. A flexible substrate having driving devices for driving a display body mounted thereon is provided on the back surface of a metal chassis which supports the display body at the back surface thereof. The back surfaces of substrates of the driving devices which are semiconductor integrated circuit devices are polished to remove unnecessary oxide films therefrom, and formed of metal films on the back surfaces. The driving devices are disposed on the flexible substrate with the metal films facing upward, a solder paste is coated on the surfaces of the metal films and the surfaces of grounding wiring patterns formed on the flexible substrate, and a metal plate is disposed on both members through the solder paste.

  • Patent number: 5590388
    Abstract: A method of producing a molded ceramic article comprises the first step mixing powdery raw materials and a liquid additive, thereby obtaining a mixed raw material, the second step press-molding the mixed raw material obtained in the first step in a hydrostatically applied condition of pressure, thereby removing an excess of the liquid additive to obtain a preform, and the third step calcining the preform obtained in the second step to obtain a molded ceramic article. The molded ceramic article comprises, as a principal component, copper and, as essential components, Cr and Ni within composition ranges of 0.1.ltoreq.Cr<2 wt. % and 0.1.ltoreq.Ni<10 wt. % and further at least one additive component selected from the group consisting of the following composition ratios: the following composition ratios: 0<Fe<5 wt. %, 0.ltoreq.Co<5 wt. %, 0.ltoreq.Al<10 wt. %, 0.ltoreq.Ti<20 wt. %, 0.ltoreq.Mo<3 wt. %, 0.ltoreq.Si<3 wt. %, 0.ltoreq.V<3 wt. %, 0.ltoreq.Mg<1 wt. %, and 0.ltoreq.

  • Patent number: 5304769
    Abstract: For resistance-welding workpieces of metal, an electrode is pressed against superposed regions of the workpieces and an electric current is supplied to the superposed regions to heat the same due to an electric resistance of the workpieces. The electrode has a body having a tip end for pressed engagement with one of the workpieces, and a matrix of tapered teeth disposed on the tip end of the body except for a center of the tip end. The teeth define recesses therebetween. One of the recesses is positioned at the center of the tip end, and the teeth are progressively higher from an outer circumferential edge of the tip end toward the center thereof.

  • Patent number: 5105284
    Abstract: A digital copier using a laser card or like external storing medium for storing image data. A remaining amount of memory capacity of a laser card is displayed in terms of the number of papers of a particular size or by percent. Based on the remaining amount of capacity, image data are compressed and reduced, the reduction ratio being also recorded in the card. When the contents of a series of documents cannot be accommodated in a single card, the first card is provided with a mark which shows that the second card is to follow.

  • Patent number: 4131490
    Abstract: There is described a marking method for distinguishing the kind, depth, position and area of surface defects of a metal piece as well as a method for detecting marks on the metal piece and a method for arranging detected signals in a electronic computer to automatically control scarfing. Shapes and colors of the marks respectively correspond to either the kind or depth of the surface defects of the metal piece. The marks are detected by a photosensitive means which can recognize colors of the marks, for example, industrial color television camera. Output signals of the camera are transmitted to the electronic computer. The computer arranges the signals and processes them to automatically control the scarfing machine.
