摘要:
A second derivative of a second-order differential equation is calculated at a reference variable value. The second derivative is multiplied by an analytical small variable value, the first derivative at the reference variable value is added, and a result is output as a first derivative after an increment of the analytical small variable value. The first derivative after an increment of the analytical small variable value is multiplied by the analytical small variable value, a physical value at the reference variable value is added, and a result is output as a physical value after an increment of the analytical small variable value.

A reactor for synthesizing hydrogen sulfide in which sulfur and hydrogen are subjected to gas-phase reaction in the absence of a catalyst to synthesize hydrogen sulfide, the reactor including: a reactor body that retains liquid sulfur in a bottom portion thereof; a heating unit that gasifies part of the liquid sulfur; a hydrogen gas supply unit that supplies hydrogen gas into the liquid sulfur; and a heat-exchanging portion provided in a gas-phase reaction region located above the liquid surface of the liquid sulfur in the reactor body, wherein heat-exchanging portion is configured such that the reaction temperature in the gas-phase reaction region is controlled to be within a predetermined temperature range by changing the heat exchange amount per unit volume in a gas-phase reaction region located farther from the liquid surface from the heat exchange amount per unit volume in a gas-phase reaction region located closer to the liquid surface.

Provided is a battery fabrication method capable of collecting foils by reforming a collector with ease and at a high quality. The battery fabrication method is to fabricate a battery (10) including an electrode body (30) formed such that a positive electrode foil (31), a part of the surface of which is coated with a positive electrode mixture, and a negative electrode foil (32), a part of which is coated with a negative electrode mixture, are stacked with a separator (33) interposed therebetween and the stacked foils are rolled. In the processes of the battery fabrication method, when the electrode body (30) is formed by the rolling, the mixture non-coated parts (35, 36) of the positive electrode foil (31) and negative electrode foil (32) are reformed by use of a reforming roll (50, 50), thereby collecting into bundles (35a,36a) a plurality of foils having different rounds in the radial direction of the electrode body (30) at the mixture non-coated parts (35, 36).

There is provided a method for producing a raw gas for ammonia synthesis in which light hydrocarbons from a tube 3, steam from a tube 6 and oxygen-enriched air having an oxygen concentration of 40 to 60% by volume from an oxygen-enriched air supply source 7 are heated and are then introduced to a one-step reforming reactor 5 to thereby carry out a steam reforming reaction and an air partial oxidation reaction at the same time, and the resultant is subsequently passed through a shift reactor 12, a decarbonating device 14 and a methanation reactor 16 to remove carbon monoxide and carbon dioxide, thereby yielding a raw gas suitable for ammonia synthesis having a hydrogen to nitrogen molar ratio of about 3:1.
摘要:
A software product and a video game device for virtually performing a card game like a trading card game. Cards of the card game are given parameters each of which shows ability point or property of the card. When a player designates a first card to present it on a field (or “summon” the first card), an index parameter given to the card is compared with a threshold. If the index parameter is over the threshold, the player must “sacrifice” some cards from cards currently presented on the field in order to “summon” the first card.

Provides is a gas mixing device capable of promptly mixing a combustible gas with a combustion supporting gas with its simple configuration, and a synthetic gas manufacturing apparatus using the device. In a gas mixing device which supplies a combustible gas and a combustion supporting gas from flow channels of a double pipe including an inner pipe and an outer pipe and mixes the gases, a first guide member guides the gas, flowing out from a gas outflow port on one end side of the inner pipe, outward, and a second guide member is formed in an annular shape along an inner peripheral wall of the outer pipe of the second guide member so that the inner peripheral portion is located closer to the upstream side than the outer peripheral portion and the inner peripheral portion is located closer to the center than the outer peripheral portion of the first guide member. In addition, a third guide member is provided so as to face a region surrounded by the second guide member.
摘要:
A method for producing a synthesis gas containing carbon monoxide and hydrogen from a source gas containing light hydrocarbons, includes the steps of: performing low temperature steam reforming by adding steam to the source gas and converting hydrocarbons of carbon numbers of 2 or higher in the source gas to methane; and performing a catalytic partial oxidation by adding oxygen after the low temperature steam reforming.
摘要:
Game software for raising interest on a card game by adding an unexpected element thereto without losing fun of thinking out a strategy. After determining an appearing face of a dice by a procedure of determining face in a turn for a player, a card attached to the determined face, which was selected from a hand by the player is determined as a battle card by a procedure of processing card battle. Offense/defense data of the battle card is read out so as to judge an outcome of the battle cards. The player is invited to freely select the card to be attached to each face of the dice from the hand, and the dice card corresponding to an appearing face is used as the battle card.
