Title: Confirming system for direction of coupling line
Inventor: KOIZUMI JIYUNICHI
IPC: G06F17/50
Filed: 1983-03-28
Abstract: PURPOSE:To ensure the accurate decision for recognition of the coupling line direction of the symbol of a logical circuit by performing totalization of weights after giving weighting to the gratings near said symbol in consideration of the difference of features between an actual coupling line and a character string and other coupling lines. CONSTITUTION:A center point address C (i, j) of a circular symbol is extracted out of a symbol recognition table. Then it is checked whether an L direction code (possibility for existence of segment in the left direction) in the grating label codes is set up or not for the center point of the circular symbol as well as two gratings L1 (i-1, j) and L2 (i-2, j) existing at the left side of said center point. In this case, the weights 2, 3 and 1 are given to the gratings C, L1 and L2 respectively, and the weights are totalized for the gratings for which the L direction codes are set up among those three gratings. Then the same operation is carried out also in the right direction. The results of totalization are compared with each other between both directions, and the larger direction is decided as a coupling line direction.

Title: Flat cathode-ray tube
Inventor: IKETA SHUNICHI
IPC: H01J29/46
Filed: 1991-03-18
Abstract: PURPOSE:To facilitate manufacturing and to enhance the quality as well as reduce the cost by sticking two borosilicate glass plates to each other through which electron-beam through-holes of an hourglass shape cross section are formed, and forming electrode films on the inlet and outlet side inclined faces of each through hole. CONSTITUTION:Electron-beam through holes 14 of an hourglass shape cross section are formed by etching through borosilicate glass plates 81, 82 and then the plates 81, 82 are positioned and stuck at their surfaces 81c, 82c to each other and electrode film 17, 18 are formed deposition method from the inlet and outlet sides of the through holes 14. The films 17, 18 are thereby attached over only the outside inclined faces 81a, 82a of the through holes 14 and not over the inside inclined faces 81, 81b and so insulation is maintained and the shape of each film is made accurate. Since the two glass plates are stuck together, mechanical strength is also enhanced. Since the electrode films are thus formed over the outside slopes of the through holes 14, manufacture is easy and the electrode films of accurate shape can be formed with insulation maintained. The quality of electrode plates can thus be enhanced and the cost of the plates reduced.

IPC: B29C63/34
Filed: 1980-04-23
Abstract: PURPOSE:To avoid occurrence of a gap between the inner wall of a flange tube and the lining outer circumference surface, by deforming the lining longer than the flange tube of an electromagnetic flow meter oscillator into a drum shape by the force of axial direction. CONSTITUTION:The lining 2 of the insulating material such as the synthetic resin, rubber causes a gap 5 between the lining 2 and the inner wall of the flange tube 1 because of longer length than the tube 1 and a difference of heat expansion by causing some gap between the tube 1 and the flange parts 1a and 1b, respectively. Such lining is produced by use of a metallic mold 4. The force of axial direction is applied to the flange parts 2a and 2b of the lining 2 by the pressing method and the like to give a deformation to the lining into a drum shape. As a result, a gap can be prevented between the outer circumference surface of lining 2 and the inner wall of tube 1. At the same time, the stress remains at the lining 2 to cause no depression to the tube path even if the negative pressure is produced within the tube 1. Thus an electromagnetic flow meter oscillator is obtained with a reduced amount of error.

Title: Expansion joint for bridge
Inventor: ODA TOSHINARI
IPC: E01C11/02
Filed: 1999-03-01
Abstract: PROBLEM TO BE SOLVED: To restrain deformation of an expansion joint at the time of earthquake or the like and exertion of damage up to the other bridge part by providing a shock absorbing material between mutual finger parts opposed by sandwiching a loose space of the expansion joint for a bridge. SOLUTION: An expansion joint for a bridge has steel material waveform comb-teeth-shaped finger parts 2 projecting in the mutually meshing direction from the mutually opposing side to support a unit load per travel wheel of a traveling vehicle, and absorbs the expansion/contraction of a bridge girder by a temperature change or the like by mutually approaching/separating a comb-teeth part. A shock absorbing material 3 composed of a rubber material is adhered and fixed to one side of the opposed finger parts 2, and a water stop seal material 4 composed of an elastic member is fitted to a lower part of a loose space 1. Even when the finger parts 2 opposed by sandwiching the loose space 1 collide with each other by an earthquake, a shock is relieved by the shock absorbing material 3. Thus, noise and vibration can be reduced, the expansion joint is hardly deformed and damage is hardly exerted up to the other bridge part, for example, post-cast concrete part 5, so that repairing is also facilitated.
