Title: Attachment mechanism for underground storage tank
Inventor: TANAKA HIROSHIGE
IPC: F17C9/00
Filed: 1980-05-02
Abstract: PURPOSE: To facilitate removal and reinstallation of an in-liquid pump by injecting water into a tank until the pump is water sealed pushing a liquefied gas up to the lower end top of a tube when the pump is removed which is arranged on the bottom of the tube inserted into a liquefied oil gas storage tank.  
     CONSTITUTION: When the in-liquid pump is removed from the storage tank 2, a water line valve 13' is opened to inject water into the tank 2 pushing up a liquefied oil gas to liquid levels 21 and 22 in the storage tank 2. Then, the valve 5' is closed while a valve 11 is opened and the liquefied oil gas is sucked out of a tube equipped with the pump by a compressor to fill the tube 7 with water. Then, a piping outlet/ inlet valve 15 for the pump is removed and the pump 8 is taken out from 10' pulling out a electric wire. To reinstall it, the pump 8 is housed in the tube 7 and the water injected is drained. This facilitates the removal and reinstallation of the pump enabling a storage tank equipment large in the depth and capacity.

Filed: 1990-03-12
Abstract: PURPOSE:To improve an S/N characteristic and to attain high sensitivity by placing a plan to color filter structure and synthesizing two lines of output signals of a solid-state image pickup element. CONSTITUTION:Four kinds of Cy, Ye, Mg, G are used as unit arrangement to a color separation filter array 11 and the stored charge is subjected to field scanning in this unit by a photoelectric conversion array 11 where photoelectric conversion elements of similar unit arrangement are arranged opposite to each other. Thus, four picture elements are mixed equivalently and a value twice the conventional luminance signal as 2(2R+3G+2B) is obtained. As a color difference signal, only one scanning among 4 field scannings is shifted by an odd number of lines and the resulting signal is mixed to apply readout of even number line in the field scanning and an odd number line to obtain a color difference signal of 2(Ye-Cy) and 2(Mg-G).
