摘要:
A method for evaluating an electrode material for a non-aqueous electrolyte secondary battery including the steps of: (A) vibrating an electrode material for a non-aqueous electrolyte secondary battery at a prescribed frequency successively in two or more levels of magnetic fields that have different magnetic flux densities; (B) detecting induced magnetizations that are synchronous with the vibrations generated in the electrode material; and (C) determining saturation magnetization of the electrode material from the induced magnetizations.

An intake air flow detecting device is provided to an intake air passage, through which intake air flows into an internal combustion engine. Intake air flow is divided into a main passage and a bypass passage. The detecting device includes a thermal air flowmeter, a bypass flow delay information calculating means, and a response delay compensating means. The thermal air flowmeter includes a detector arranged in the bypass passage for detecting an air flow amount in the intake air passage. The bypass flow delay information calculating means calculates a bypass flow delay information representing delay in variation in a flow amount in the bypass passage with respect to variation in a flow amount in the main passage. The response delay compensating means compensates delay in response of the air flowmeter in accordance with the bypass flow delay information.

An apparatus for reducing the amount of carbon dioxide released into the atmosphere by fixing and dumping carbon dioxide which is disposed in seawater or fresh water satisfying certain temperature and pressure conditions for the formation of carbon dioxide hydrate or its clathrate comprising:a) a transport pipeline equipped with a compressor;b) a carbon dioxide source connected to said transport pipeline upstream of said compressor;c) a plurality of ejector nozzles disposed at one end of the pipeline;d) a reaction housing which allows seawater or fresh water and carbon dioxide to react with each other and form the carbon dioxide hydrate or its clathrate;e) a dispersing propeller;wherein the reaction device is provided with the ejector nozzles and the dispersing propeller at the inlet portion of the device; the concentration of the carbon dioxide is supplied into the pipeline and is discharged by the compressor into the reaction housing from the ejector nozzles under pressure to form the carbon dioxide hydrate or its clathrate; the thus produced hydrate or its clathrate is dispersed by the propeller out of the reaction housing to the deep bottom of the sea.

A copolymer for semiconductor lithography, comprising at least a recurring unit (A) having a carboxylic acid ester structure whose solubility in alkali increases by the action of an acid and a carboxyl group-containing recurring unit (B), which copolymer is obtained via a step (P) of (co)polymerizing at least a monomer giving a recurring unit (A) and a step (Q) of forming a recurring unit (B) in the co-presence of a recurring unit (A)-containing (co)polymer and/or a monomer giving a recurring unit (A), and an acid. The copolymer is used in production of semiconductor as a resist polymer which is small in roughness, little in development defect and superior in lithography properties such as DOF and the like.
摘要:
An emission control system has a catalyst and a sensor responding to a component of exhaust gas. In order to speed warming up the catalyst, the emission control system increases the amount of heat dissipated by exhaust gas. A diagnosis of the emission control system is carried out by determining whether the amount of heat dissipated by exhaust gas is sufficient or insufficient. The amount of heat dissipated by exhaust gas is represented by the length of time to an activated state of the sensor. In the diagnosis, the amount of heat generated by a heater provided in the sensor is taken into consideration.
摘要:
A fuel injection control system for an internal combustion engine which can eliminate lean misfiring and rich misfiring at asynchronous injection and exhausting of non-combustioned HC. When the asynchronous injection is performed at engine cranking or at acceleration, a judgement is made as to whether the injected fuel will be divided by closure of an intake valve. When division is not detected, fuel injection is performed in normal manner. When division is detected, rate of the fuel division is computed. As a result of computation, fuel injection is performed when judgement is made that a predetermined amount of the injected fuel will be introduced into the cylinder. Furthermore, the amount of fuel not introduced into the cylinder is computed to reduce a corresponding amount from a fuel injection amount for the next cycle. On the other hand, when judgement is made that the predetermined amount of fuel will not be introduced into the cylinder, fuel injection does not take place.

A method of forming a positive resist composition of the present invention includes a step (I) of passing a positive resist composition, which is obtained by dissolving a resin component (A) that displays increased alkali solubility under the action of acid and an acid generator component (B) that generates acid upon exposure in an organic solvent (S), through a filter (f1) equipped with a nylon membrane, wherein the resin component (A) is a copolymer containing at least two structural units obtained by polymerizing at least one monomer in the presence of acid.
