Title: Fluorescent display tube
Inventor: MATSUKI NOBUYUKI
IPC: G03G15/04
Filed: 1989-11-30
Abstract: PURPOSE:To obtain printed images free from distortion and to allow the early attenuation of the oscillation of a cathode filament by providing a current control means which maintains the current flowing from grids to the cathode filament at a specified value. CONSTITUTION:The current control means 129 which maintains the current flowing from the grids 15, 16 to the cathode filament 17 at the specified value is provided. Even if, therefore, the cathode filament 17 oscillates and the distance between the cathode filament 17 and the grids 15, 16 fluctuates, the cathode filament voltage increases in correspondence to the increased component of the grid current when the grid current increases. The potential difference between the grids 15, 16 and the cathode filament 17 is thereby decreased. As a result, the voltage acts in the direction to decrease the current flowing from the grids 15, 16 to the cathode filament 17 and the quantity of the light emitted by the fluorescent display tube 1 is maintained constant. The oscillation of the cathode filament is attenuated early as well.

Title: Tail pipe of gas turbine combustor
Inventor: UMEZAWA SADAO
IPC: F23R3/50
Filed: 1987-12-11
Abstract: PURPOSE:To reduce creep deformation due to pressure difference in a tail pipe by providing at the center of a tail pipe a strut which is interiorly hollow and pieces the tail pipe from the inner wall to the outer wall and through the hollow space of which the discharged current of air is in part made to flow so as to cool the strut from the inside. CONSTITUTION:A strut 9a of a supporting means 9 is interiorly hollow and provided on the interior surface with fin-shaped protrusions 10 and pin-shaped protrusions 15. Part of the discharged current of air 17 is made to flow directly to the outer side through this hollow space in the supporting means 9. Although heated on the inner side by the heat transfer by the gas current, a tail pipe 1 is thus cooled on the outer side by the heat transfer by the discharged current of air and its temperature is maintained below an allowable limit. Since the gas current 2 impinges at high velocities upon the strut 9a of the supporting means 9, the heat transferred from the gas current is especially large at the forward edge portion of the strut 9a. On the other hand, the inner side of the strut 9a at the forward edge is provided with many fin-shaped protrusions 10, upon which the discharged current of air 17 flowing through the strut impinges, resulting in a turbulence of air, and thus the heat transfer with a cooling effect takes place also at a large rate.

Title: Degeneration system for coupled area
Inventor: OTA YOSHIYUKI
IPC: G06T3/00
Filed: 1989-11-30
Abstract: PURPOSE:To extract a degenerating point of a picture having any complicated shape with two picture scanning operations by performing a degeneration candidate point calculation processing which keeps only the end points of an area as the candidates of degenerating points and a degeneration candidate point update processing which keeps a degenerating point in an area out of plural degeneration candidate points to obtain the degenerating point of each area. CONSTITUTION:The temporary labels are given to the picture elements forming each area based on the states of picture elements included a window of (2 X3) picture elements after scanning this window for a binary picture. At the same time, the degenerating point of each area is obtained via the picture scanning which uses a degeneration candidate point calculation processing 1 which keeps only the end points of an area as the degenerating point candidates and a degeneration candidate point update processing 2 which keeps a degenerating point in an area out of plural obtained degeneration candidate points. Thus it is possible to degenerate plural areas scattered to the binary pictures divided into '0' and '1' from a picture based on the threshold value into a single point at a high speed and in a fixed processing time.
