A control device for an internal combustion engine capable of controlling an intake-pipe pressure within a range which allows restartability to be ensured. A control device for an internal combustion engine includes: an idle-stop control section for restarting the engine in response to generation of a restart request; and an intake-air amount control section for setting a control amount of an intake system so that the intake air amount becomes zero when an intake-pipe pressure of the engine upon generation of the automatic stop request is higher than a predetermined pressure and setting the control amount of the intake system so that the intake air amount becomes larger than the amount upon generation of the automatic stop request, and then becomes zero when the intake-pipe pressure is lower than the predetermined pressure.

The present invention is to provide a wireless communication system that is capable of preventing occurrence of radio interference caused by radio wave used by a radio wave generator without requiring any improvement of existing wireless devices. The wireless communication system of the present invention includes: a radio wave generator (1) that uses at least a radio wave in a frequency band that overlaps a frequency band used by a wireless standard; and wireless devices (AP, STA) each of which uses a radio wave conforming to the wireless standard. The radio wave generator (1) transmits a dummy frame conforming to the wireless standard to the wireless devices near the radio wave generator (1) before generating the radio wave in the same frequency band as the frequency band used by the wireless standard. When the wireless devices (AP, STA) receive the dummy frame, the wireless devices (AP, STA) control themselves to stop using the radio wave in the frequency band that has radio interference caused by the radio wave generated from the radio wave generator (1).

摘要:
A mobile communication network system is capable of achieving both of route optimizing function and demand for privacy protection. An address server determines network addresses to be assigned for a plurality of variable IP subnetworks and use period of the network addresses, and distributes network addresses to routers having foreign agent function in the variable IP subnetworks. When use period of the assigned network address expires, new network address of own router is at first assigned. Addition of the subnetwork having new network address is notified to respective routers of the fixed IP subnetworks using IP route control means.

A system includes a storage for storing positional information of telephone terminals, a determiner for being notified of a called telephone terminal by an exchange which received a call from a calling telephone terminal, and determining whether the called telephone terminal is in a particular area, and an indicator for, if the called telephone terminal is in the area, retrieving a telephone terminal in a range based on the called telephone terminal, as a neighboring terminal, and indicating the neighboring terminal to the exchange. The exchange includes a requester for sending a connection request to another exchange, to request that a connection be made between the called telephone terminal and the neighboring terminal, and a caller for receiving a connection request from another exchange and sending a call to a telephone terminal which is assigned by the connection request.
摘要:
At the time of start-up, fuel supply is made excessive. When air-fuel ratio feedback control is started while the fuel is excessive, the control is put into a state of overshoot or hunting, and it takes a long time to converge to the target air-fuel ratio. In an air-fuel ratio control apparatus, a selection switch is provided at the output of an integration calculation circuit to perform air-fuel ratio feedback control, and immediately after start-up of the engine, an upper/lower limit clip value for use immediately after start-up, which is smaller than a normal one, is selected to perform the air-fuel ratio feedback control. Even if the air-fuel ratio feedback control is started immediately after the start-up in a state where the fuel is excessive, the actual air-fuel ratio does not overshoot with respect to the target air-fuel ratio and is quickly converged to the target air-fuel ratio.
摘要:
A control apparatus for an internal combustion engine can detect degradation of a three-way catalyst with high accuracy without causing deterioration in an exhaust. A pair of first and second air fuel ratio detectors are disposed in an exhaust system at locations upstream and downstream of the three-way catalyst for detecting a first and a second air fuel ratio of an exhaust gas. A target oxygen change amount calculator calculates a target oxygen change amount of the three-way catalyst, and an oxygen change amount calculator calculates an oxygen change amount of the three-way catalyst from an amount of exhaust gas passing through the three-way catalyst and the first air fuel ratio. An air fuel ratio operator inversely controls the air fuel ratio to a rich side and a lean side with a prescribed air fuel ratio width each time the oxygen change amount reaches a target oxygen change amount.
