Title: Fuel supply control device of internal combustion engine
Inventor: NAGAISHI HATSUO
IPC: F02D45/00
Filed: 1988-05-18
Abstract: PURPOSE:To provide enhanced accuracy of the fuel supply control and responsiveness even though there is response delay in an air flow meter at transient or ripple error by correcting the smoothing supply amount with a prefetch correction amount computed on the basis of the change amount of the air flow amount. CONSTITUTION:In a control unit 30, the fundamental fuel supply amount is calculated on the basis of the suction air amount sensed by an air flow meter 7 and the number of revolutions sensed by a crank angle sensor 10. This fundamental supply amount is smoothened, and the smoothened supply amount is computed. The suction air amount is calculated from the degree of opening of a throttle valve 8 sensed by a throttle opening sensor 9 and the number of revolutions of an engine 1, and the prefetch correction amount is computed on the basis of the change amount of the suction air amount. The smoothing supply amount is corrected with this prefetch correction amount, and the final fuel supply amount is calculated. This allows smoothing the fundamental pulse width of an injector 4 with high accuracy and good response, and the pulse width corresponding to the flow rate in the injector 4 part can be corrected properly with the prefetch correction.

Title: Line fault detection system
Inventor: FUJIOKA TAKAHIRO
IPC: H04B3/46
Filed: 1989-05-17
Abstract: PURPOSE:To allow a master equipment to detect quickly a fault point when the fault occurs in a line by discriminating the fault such that it is the fault of a 1st line when a main reception section cannot receive a reply even after the prescribed time T1 elapses after the data transmission of the main transmission section and it is the fault of a 2nd line when other data cannot be received even after the time T2 elapses. CONSTITUTION:Upon the receipt of a notice of a command transmission, a main control section 321 sends a 1st operating start signal to a timer 322 whose operating time is T1 to set the timer and sends a switching control signal to switch SW1, SW2 to the position of (b). Thus, a response from a slave set is fed to a main reception section via a transmission line. Even when a status requesting command is sent from the master equipment and no reply comes within the time T1, the main control section detecting a timeout signal discriminates it as the fault for the transmission line or a slave equipment. Moreover, when the data representing the operating state cannot be received within the time T2 after the response is returned, the main control section detecting the timeout signal discriminates it to be the fault of a reception line or the slave equipment.

Abstract: PURPOSE: To attain uniform irradiation under no influence of scanning distortion and beam-current variation through electromagnetic beam-scan control in accordance with the difference between a beam-center position against an irradiated sample and an integrated value of a beam current.  
     CONSTITUTION: Beam 51 led out from an ion source and sample-analyzed is adjusted by quadruple-pole lens 52 to obtain a circular section. This beam is scanned  by scanning electrodes 55' and 55 in the X and Y directions respectively. Then, current outputs (i 1 ) and (i 2 ) from monitor 53 are converted by circuit 56 into voltages  which correspond to the Y-directional beam-center position and the integration  value of the beam current. In accordance with the digfference between both these  converted voltages, a voltage is controlled which is applied to scanning electrode  55' via circuit 57, thereby making Y-directional uniform irradiation. Further, the  beam having passed through slit 58 is deflected and scanned in the X direction by  parallel scanning electrode 59 bent in the X direction. In the same way as before,  the voltage applied to scanning electrode 59 is controlled by monitor 60 and circuits  61 and 62, thereby making X-directional uniform irradiation. In this way, irradiated sample 63 is irradiated with the beam controlled in two dimentions X and Y
