Title: Display device with fluorescent character display tube
Inventor: SAKAGUCHI SHIYOUZABUROU
IPC: H01J31/12
Filed: 1983-07-07
Abstract: PURPOSE:To obtain high resolution and large-sized display by providing both sides of an insulating plate having plural holes arranged in the matrix shape with a line grid electrode group and a column grid electrode group while applying a phosphor uniformly on the anode electrode. CONSTITUTION:Assuming that the grid electrodes GA1 and GB1 attached to both surfaces of an insulating plate 3 are impressed by voltage +B1, thermal electrons from a filament F pass through the holes 1-1 while reaching the anode electrode A. Thereby, said thermal electrons collide with a phosphor L applied on the anode electrode A so that the part directly under the holes 1-1 and in their neighborhood are to radiate. At least either of the upper-and-lower grid electrodes of the holes excepting the holes 1-1, at which the grid electrodes GA1 and GB1 intersect, is pulled down to earth potential so that the grids are reversely biased to the filament F thus making the electrons unable to pass said holes. Accordingly, optional two-dimensional picture display is possible by scanning said grid electrodes by turns.

IPC: F16H61/16
Filed: 1991-04-26
Abstract: PURPOSE:To prevent the generation of unexpected speed change shock by constructing a speed change control device for a vehicular automatic transmission in such a way as to continue the inhibition of shift into a specific speed change stage until the speed change requested state comes back again after the speed change requested state is once taken off when the specified speed change forbidding condition becomes unsatisfied. CONSTITUTION:A speed change forbidding condition judging means 112 judges whether a speed change forbidding condition is satisfied on the basis of input information 122, and outputs the judgment to a shift forbidding means 114. A speed change requested state judging means 110 judges whether the speed change requested state is required to be in a specific speed change stage from the input information 120, and outputs the judgment to the shift forbidding means 114. The shift forbidding means 114 forbids the shift into a speed change stage while the speed change forbidding condition is satisfied. When the speed change forbidding condition becomes unsatisfied, the inhibition of shift into the speed change stage is continued until the speed change requested state comes back again after the speed change requested state is once taken off.

Title: Lattice-like folded sheet structure
Inventor: KUKIHARA TAKEAKI
IPC: E04C2/36
Filed: 1989-05-17
Abstract: PURPOSE:To obtain the way to fold, by which lattice structure as strong as honeycomb core is formed, by a method wherein the structure concerned is made by folding flat plate along folding lines, which consist of group of bent lines having two or more slopes different in absolute value and group of parallel straight lines meeting the bent lines at their bending points. CONSTITUTION:Folding lines consist of group of bent lines (heavy lines) and group of parallel lines (fine lines) meeting the bent lines. Solid line represents projected folding (negative folding angle) and dashed line represents recessed folding (positive folding angle). The bent line is a solid bent line or a dashed bent line. The straight line meeting the bent lines is one straight line, in which solid line parts and dashed line parts are alternately connected to each other. The group of the straight lines meet the bent lines at their bending points. How to fold is enough for producing slight folding such as marking or the like at first and, after the production of the slight folding, the simple application of pressure from the neighborhood of the slight folding causes to proceed the automatic folding. The folding angle interlocks the front face of stock over its whole face by the geometrical action of structure. The folded-up structure already had considerable rigidity as its is.
