Patent JP-H03186799-A (JP)
Title: Nuclear reactor container
Inventor: TAGAWA HISATO
IPC: G21D3/08
Filed: 1989-12-18
Abstract: PURPOSE:To more surely avoid the generation of detonation by a method being profitable in its cost, as well by providing a means for suppressing a combustion reaction itself of hydrogen accumulated in a container. CONSTITUTION:The generation limit of detonation is determined by a relation of the scale of a detonation cell and the size of a containment 1, and when the size of the detonation cell is larger than the vessel, the detonation is not generated. The size of the detonation cell is determined by a combustion reac tion speed of gas. That is, when the combustion reaction is suppressed, even if the container 1 is large, the detonation comes not to be generated. That is, when the gas combustion reaction speed is suppressed so that the detonation cell becomes larger than the size of the container 1, even if concentration of inflammable gas exceeds an inflammable limit, generation of detonation can be prevented. Therefore, to an injecting device 4 of CO2 gas, a CO2 cylinder 5 and a CO2 concentration monitor 6 are connected. When CO2 gas of about 20% is mixed in addition of nitrogen gas substitution at the time of regular operation by this equipment, generation of detonation is prevented at the time of accident, and soundness of the container 1 and the equipment in the container can be held.

Title: Solid-state image pickup element
Inventor: TAGAMI YOSHITOMO
IPC: H04N9/07
Filed: 1989-12-19
Abstract: PURPOSE:To prevent production of flicker and longitudinal stripe by using a signal obtained from a color filter element arranged to all lines so as to detect a level difference between fields, using the level difference so as to eliminate the level difference between fields prior to signal processing. CONSTITUTION:The G stripe R/B checkered pattern arrangement F1 is adopted for the arrangement of color filters. In the case of the processing of a 2nd field, a circuit 22 is used to obtain a difference DG in the vertical direction of a G signal. When the difference DG is smaller than a setting level Vth, it is discriminated that the difference DG is an inter-field level difference caused by interlace readout. Then a digital switch 23 replaces a 2nd field signal G2, 2 into a 1st field signal G1, 2 latched by a circuit 21. When the signal is processed by using the corrected data, since the small level difference between fields in the G signal is eliminated, the flicker caused by the level difference of the G signal is eliminated.
