Title: Catalytic hydrogenation of carbon dioxide gas
Inventor: SASAKI YOSHIYUKI
IPC: C01B32/40
Filed: 1993-03-12
Abstract: PURPOSE:To produce methanol, methane, carbon monoxide, etc., by hydrogenating carbon dioxide gas in the presence of a homogeneous liquid-phase reaction catalyst. CONSTITUTION:Methanol, methane, carbon monoxide, etc., are produced by hydrogenating carbon dioxide gas in the presence of a homogeneous liquid-phase reaction catalyst consisting of a combination of a ruthenium carbonyl complex with an iodine compound. Methanol, methane or carbon monoxide useful as a fuel or a chemical synthesis raw material can be produced from carbon dioxide gas exhausted in large quantity from a thermoelectric power plant, cement factory, etc. Since the catalyst is soluble in solvent in contrast with conventional heterogeneous catalyst, it can be used in a liquid-phase reaction system at an easily controllable temperature.

IPC: G01V3/08
Filed: 1989-03-06
Abstract: PURPOSE:To enable highly accurate detection without requiring a high accuracy for a shape and position of an electrode or the like by arranging a pair of screens moving integral axially at a fixed interval. CONSTITUTION:Cylindrical common electrodes 34 are arranged at a fixed interval with a fixed clearance on the inner circumference of first and second electrodes 14 and 16 disposed in proximity within a cylindrical case 12. A pair of screens 50 and 52 is so arranged that it can move integral axially within the clearance while a fixed ring-shaped space is formed axially. Then, as a spindle 54 is shifted axially, the screens 50 and 52 are shifted axially together, when capacities of the electrodes 14 and 16 and the electrode 34 developed through the ring-shaped space changes with a movement of the space. Such a capacity difference between the electrodes 14, 16 and 34 is picked up from a lead 48 to be detected as variation of a movement of the spindle 54. An apparatus thus obtained is inexpensive because there is no need for securing a dimensional shape accuracy and an assembling position relationship of the electrodes and enables highly accurate detection.

Abstract: PURPOSE:To realize high attenuation without saturating a high frequency amplifier FET by operating a second attenuation circuit after surely operating a first attenuation circuit when the electric field strength of an input signal exceeds a second level higher than a first level. CONSTITUTION:When the input signal level of an antenna input terminal exceeds a first electric field strength level, a first attenuation command signal V1 is generated from the sixth terminal of an FM front end IC, and the first attenuation circuit D5 is operated, and the Q of an antenna tuning circuit 1 is decreased, and the input signal is attenuated, and variable capacitance diodes D1 and D2 in the tuning circuit can be protected from a high input signal.
