A method and system of arranging advertisements on a network for a potential media owner or affiliate to sell ad space on a network media to an advertiser. The advertiser's conditions and the affiliate's acceptance are made on the network through an agent's server. The server provides an invitation page for entry of the advertiser's conditions. The conditions are disclosed to the affiliate on the network. When the affiliate accepts the conditions on the network, the agent's server responds to make an advertisement contract, and allocates an advertiser's web site to the ad space of the network media. The number of the responses made to the advertisement is counted at the agent's server, which delivers statistical data of the counted responses on the network to the advertiser and the affiliate for determination of the payment and for evaluation of the effectiveness of the advertisement.

Provided is a game screen display controlling method comprising the steps of displaying a first game screen obtained from a first projection of a virtual 3-D space; comparing the priority of the first projection with the priority of a second projection correlated with a predetermined area when there is a predetermined positional relationship between a character who moves in the virtual 3-D space and the predetermined area set within the virtual 3-D space; and displaying a second game screen obtained from the second projection of the virtual 3-D space when the priority of the second projection is higher than the priority of the first projection. Thereby, the invention allows game pictures for effectively rendering the virtual 3-D space to be presented corresponding to the situation of the game.

A throttle valve control device is provided which includes a throttle valve mounted in an intake pipe of an internal combustion engine, an actuator which drives the throttle valve so as to change an opening of the throttle valve, an operating condition sensor which detects operating conditions of the internal combustion engine, an accelerator sensor which detects an accelerator pedal position that represents an amount by which an accelerator pedal is depressed by a driver, and a control unit for controlling the throttle valve. The control unit includes a first setting circuit that sets a first target opening of the throttle valve based on the accelerator pedal position detected by the accelerator sensor, a second setting circuit that sets a second target opening of the throttle valve based on the accelerator pedal position detected by the accelerator sensor, and the operating conditions of the engine detected by the operating condition sensor, and a control circuit that compares the first target opening with the second target opening, and controls the actuator based on the larger one of the first target opening and second target opening.

A method and apparatus for detecting faults in a fuel evaporative emission control system, in which the fuel evaporative emission which is admitted from a fuel tank and adsorbed once by a canister is separated from the canister by purge air and sucked into a suction passage of an engine. The fault diagnostic apparatus fluid-tightly closes the fuel tank such that a vacuum is held in the fuel tank, and then detect the presence of a leak in a fuel evaporative emission flow path on the basis of a rate of increase of the pressure in the fuel tank. At the same time, the average value of the pressure in the fuel tank is calculated at regular intervals, and the calculated average value is compared with levels of the pressure in the tank detected within a predetermined period of time, so that the detection of the leak is interrupted depending upon the result of the comparison.

A detecting apparatus for a catalytic converter has a pair of O.sub.2 sensors, arranged individually on the up- and downstream sides of the converter, and an electronic control unit for discriminating reduction of the purifying capacity of a three-way catalyst in the converter. This unit discriminates the reduction of the purifying capacity in accordance with the comparison between a decision value and the ratio between the respective frequencies of outputs from the O.sub.2 sensors. In the case where the O.sub.2 sensor on the upstream side is subject to thermal degradation, its decision value is corrected, or the decision itself is interrupted.

This invention relates to a control system for the quantity of air to be inducted, which is suitable for use in controlling the idling speed of an engine, for example, for an automotive vehicle or the like. It is an object of the present invention to permit a change of the same degree to the quantity of air to be inducted for the compensation of a load without being affected by the temperature of the engine and also to precisely obtain inducted air in a quantity required inherently. The control system is constructed of STM valve (12) interposed in a bypass passage (11) of a throttle valve (8), ROM (36) for storing opening data for the setting of the position of the STM valve (12), the opening data corresponding to engine operation states, a limiter (13) interposed in the bypass passage (11) in series with the STM valve (12), the opening of the limiter being variable depending on the engine temperature, target opening setting device (45,46) for correcting a target opening on the basis of the engine temperature upon setting the target opening on the basis of the opening data obtained from the ROM (36) in accordance with an engine operation state, and an ISC driver (44) for controlling the opening of the STM valve (12) to the target opening from the target opening setting device (45,46).

A misfire detection method is provided, which method makes it possible to accurately detect the occurrence/absence of misfire by eliminating a detection error in misfire detection. This error is caused by a vibrational increase or decrease of the rotational changing rate of a crankshaft after a misfire state occurs. A processor, which receives pulse outputs from a crank angle sensor, calculates in sequence angular accelerations D.omega..sub.n-2, D.omega..sub.n-1, D.omega..sub.n, and D.omega..sub.n+1 in crank angle areas which correspond to a preceding cylinder, two cylinders checked for misfire, and a succeeding cylinder, respectively. If the values D.omega..sub.n-1 and D.omega..sub.n n significantly decrease in comparison with the values D.omega..sub.n-2 and D.omega..sub.n-1, respectively, then it is tentatively determined that misfire has occurred in both cylinders checked. Then If the value D.omega..sub.n+1 significantly increases compared to the value D.omega..sub.n, then the restoration to the normal combustion state is confirmed, and the occurrence of misfire in the two cylinders checked is definitely determined.
摘要:
A method and apparatus of detecting faults for a fuel evaporative emission treatment system, in which the fuel evaporative emission which is admitted from a fuel tank and absorbed once by a canister is separated from the canister by purge air and sucked in a suction pipe of an engine. Under the control of an electronic control unit, a vent port of the canister is closed by closing a vent solenoid valve, and a purge control valve installed in a pipe connecting an outlet port of the canister to the suction pipe is opened. Thereby, a negative pressure of suction air is applied to the fuel tank via another pipe connecting the above-mentioned pipe and the inlet port of canister to the fuel tank to reduce the internal pressure of the fuel tank. Then, the reduction of the internal pressure of the fuel tank is completed by closing the control valve. Afterward, the pressure rise generated in the fuel tank from the time when the exhaust is completed is detected on the basis of the output of a pressure sensor. If the degree of pressure rise is high, it is judged that the fuel evaporative emission system has a fault such as poor airtightness.
