Title: Vapor fuel processing device
Inventor: YUDA SHIYUUJI
IPC: F02D41/02
Filed: 1994-04-22
Abstract: PURPOSE:To prevent a base air-fuel ratio from being learnt falsely by allowing the purge to be carried out when a volume of fuel is contained in purge gas, and stopping the purge to allow the learning of the base air-fuel ratio to be carried out when the amount of fuel in the purge gas becomes less than a specified amount of fuel. CONSTITUTION:In order to control the air-fuel ratio detected by an air-fuel ratio sensor 121 to a target air-fuel ratio during operation of an engine, a control unit 15 calculates the opening time of a fuel injection valve 111, and based on the air-fuel ratio feedback coefficient utilized at this time, the control unit learns the concentration of vapor fuel to be purged into an intake pipe. Further, the control unit learns a base air-fuel ratio based on the calculated air-fuel ratio feedback coefficient. In this case, when the learning of the base air-fuel ratio is completed at the time of learning the base air-fuel ratio, and when the learning of the base air-fuel ratio is not completed and it is judged that the concentration of the vapor fuel contained in purge gas is high, the control unit operates to open a purge valve 142, and prohibit the learning of the base air-fuel ratio.

IPC: H01L23/12
Filed: 1980-06-24
Abstract: PURPOSE:To equivalently reduce the parasitic capacitance between the drain and gate of a transistor and raise the self neutralization frequency, by connecting an inductance between said drain and gate. CONSTITUTION:A DC circuit comprising an inductance 15 and a DC-blocking MOS capacitor 16 is connected in parallel with a parasitic capacitance 9 between the drain and gate.

Abstract: PURPOSE:To simplify extremely the circuit constitution for polling by sending a polling sign or a reference pulse in addition to said signal to each transmitter from a controller and sending the pulse from the transmitter having a request for transmission within the time corresponding to its own device number to inform the request for transmission to the controller. CONSTITUTION:A controller 3 sends a polling sign to each transmitter 1 and then divides the time for each fixed period from a standard time point to allocate the corresponding divided time to each transmitter. It is enough for each transmitter just to decide the reference time point, and controller 3 can also send a reference pulse following the polling sign. Here the transmitter if requests transmission transmits the pulse within the divided time corresponding to its own device number. The controller 3 detects this pulse and checks a specific divided time section where the pulse exists to judge the transmitter having a request for transmission.
