Title: Carbon dioxide absorbing material
Inventor: NAKAGAWA KAZUAKI
IPC: C01B32/50
Filed: 1997-09-16
Abstract: PROBLEM TO BE SOLVED: To recover carbon dioxide directly by separation at a high temperature at a low energy consumption by a method wherein an oxide in which lithium is solid dissolved is contained, and reacted with carbon dioxide gas at a specific temperature or under to generate lithium carbonate. SOLUTION: The carbon dioxide gas-absorbent contains an oxide in which lithium is solid dissolved. and reacts with carbonic acid gas at 450 deg.C or under to generate lithium carbonate. As a gas containing the carbon dioxide gas, a gas or the like generated in processes of an apparatus such as an engine using a fuel having, for example, hydrocarbon as a main constituent, a power generation plant, and a chemical plant is exemplified. As the oxide in which lithium is solid dissolved, lithium peroxide containing at least one kind selected from aluminum, titanium, iron, nickel, and silicon, is exemplified. By adding further an alkali carbonate selected from lithium, sodium, and potassium to the oxide, an absorption and release reaction of carbon dioxide gas of the obtained absorbent is accelerated.

Title: Diaphragm position automatic adjusting mechanism for electron microscope
Inventor: IIDA YASUO
IPC: H01J37/09
Filed: 1997-09-18
Abstract: PROBLEM TO BE SOLVED: To maintain the state of diaphragm alignment at the beginning of observation for a long time by adjusting the diaphragm position so that an electron beam ratio of a pair of electrodes on an incidence plane of the electron beam is kept being constant. SOLUTION: After irradiating diaphragm alignment, an electron beam is made incident on an electrode 30, beam signals Ia, Ib are inputted to a beam comparison detector 32, and the signal ratio K of the beam signals Ia, Ib is inputted to a Y axis control circuit 33. An electron beam 4 is absorbed by the electrode 30 and a diaphragm 25, heat converted, and conducted to a drive mechanism 23 through a diaphragm fixing axis 24. The drive mechanism 23 is thermally expanded, due to its being surrounded by vacuum which prevents heat from being radiated, causing a shift of an optical axis 4', and the beam detecting currents Ia, Ib change, resulting in the change of the ratio K of both to ratio K'.  The ratio of both currents is made 0 by supplying the output signal which is proportion to the difference the ratios from the Y axis control circuit 33 to a drive motor 35 to control the irradiating diaphragm position. As a result, the diaphragm position is kept to be in the position at the time of completion of alignment regardless of the thermal expansion.

Title: Impact pressure relay for gas insulated electric apparatus
Inventor: SAITO SHIGEMI
IPC: H01H35/34
Filed: 1987-10-09
Abstract: PURPOSE:To make a pressure variation in sealed gas attendant upon an internal accident detectable in full by setting up a rubber diaphragm small in a spring constant between two closed structural chambers. CONSTITUTION:A rubber diaphragm 30 with flexibility is set up between an upper case 11 and a lower case 12, and a switch 13 operating by the variation is connected to this diaphragm 30. When an internal accident or abnormal current-energization occurs in this gas insulated apparatus, differential pressure is produced between a pressure chamber 20 and a switch chamber 2 by line resistance in a fine tube 15, due to a sudden pressure variation attendant upon a sudden temperature rise, therefore the diaphragm 30 is deformed, whereby the switch 13 connected to the diaphragm 30 operates. Since rubber material excellent in flexibility is used for the diaphragm 30, a spring constant is sharply reducible as compared with a metallic bellows. For this reason, displacement of the diaphragm 30 can be largely taken up, so that the switch is made operable with a low pressure differential.
