摘要:
The present invention intends to provide a lithium primary battery excellent in large-current discharge characteristics in a low temperature environment without sacrificing the high-temperature storage characteristics. The present invention relates to a lithium primary battery including a positive electrode including a fluoride as a positive electrode active material, a negative electrode including metallic lithium or a lithium alloy as a negative electrode active material, a separator interposed between the positive electrode and the negative electrode, and an electrolyte. The positive electrode further includes a metal oxide being capable of absorbing and desorbing lithium ions, having a spinel structure, and having a discharge potential versus lithium lower than that of the fluoride.

A gas trubine combustor includes a main body with a combustion portion into which mixture of fuel and air is supplied. The gas mixture is burned through a catalytic reaction at a catalyst body arranged in the main body. The gas mixture passed through the catalyst body is introduced into a gas phase combustion portion provided in the main body. Between the catalyst body and the gas phase combustion portion is arranged a dividing unit which has a plurality of branch passages. The gas mixture passed through the catalyst body is divided by the dividing unit into a plurality of gas streams flowing through the branch passages. Each of the gas streams is mixed with fuel supplied from a fuel supply tube.

A coin-shaped battery includes a cathode case (1) having a crimp portion (14) in the periphery of a bottom face (1a), and an anode cap (2) having a flange (6) with an extended portion (7) and a turn-up portion (8). Openings of cathode case (1) and the anode cap (2) are sealed by crimping with a gasket (3) interposed therebetween, so that the gasket (3) is compressed between the crimp portion (14) having a U-shaped cross section, the flange (6), the extended portion (7) and the turn-up portion (8) to effect reliable sealing. Thus, it is possible to disperse a deformation pressure, which is generated by bulge of the cathode case (1) and the anode cap (2) caused with a rise in internal pressure of the battery under severe working conditions such as use under a high temperature. As a result, the coin-shaped battery having improved liquid leakage resistance in the crimped portion is provided.

A down-drafting constant vacuum pressure type diaphragm carburettor includes a carburettor body with an induction passage, a throttle valve, a Venturi portion variable of open area. A vacuum actuated valve is arranged at upstream side of the throttle valve across the induction passage and extending in horizontal direction from one side to the other side, and controls an open area of a Venturi portion depending upon a vacuum pressure generated in the Venturi portion. A jet needle is mounted on the vacuum actuated valve. A fuel control system including a diaphragm arranged between a recessed portion of the carburettor body and a cover covering for defining a regulator chamber at the side of the recessed portion and an atmospheric pressure chamber at the side of the cover, and a valve seat. The diaphragm is arranged at lower side of a longitudinal axis of the jet needle.

A gasket-integrated case is obtained by punching out a circular piece from a metal sheet on which a gasket resin film having a round hole is integrally laminated with an adhesive, in such a way as to have a diameter concentric with, but larger than, the round hole, and by drawing the circular piece into a bottomed cylindrical shape. Elements for electromotive force and a sealing plate are then disposed on the case, and the periphery of the sealing plate is sandwiched and sealed by the periphery of the case by crimping, with a gasket including the resin film interposed therebetween, so that a coin-shaped battery is formed. The resin film has a thickness in the range of 20 &mgr;m to 150 &mgr;m and a modulus of elasticity equal to or greater than 35 kgf/mm2.

In an embodiment, a CO2 recovery system has an absorber, a regenerator, and a circulation device. An absorption liquid has an aqueous solution of amine having an alcohol group, and dimethyl silicone oil in which a part of methyl groups is substituted by at least one type selected from an aminoalkyl group, a carboxyl group, and a hydroxyl-containing alkyl group. The absorber contacts a combustion exhaust gas of a fossil fuel and the absorption liquid to absorb CO2, which is contained in the combustion exhaust gas, into the absorption liquid. The regenerator releases CO2 by applying thermal energy to the CO2-absorbed absorption liquid. A circulation device circulates the absorption liquid between the absorber and the regenerator.
