Title: Fuel injection controller
Inventor: OSAKABE TETSUYA
IPC: F02D41/00
Filed: 1985-05-28
Abstract: PURPOSE:To prevent the generation of engine stall and improve starting performance by installing a means for detecting the switching to the start traveling engagement state of a transmission and a means for detecting the connection of a clutch and a control circuit for jetting an increased quantity of fuel. CONSTITUTION:A control circuit 4 receives each input of the first speed position signal from an engagement position switch 26 and a clutch connection signal from a clutch switch 30 and outputs the injection pulses in the increase of fuel quantity for the immediate injection of the increased quantity of fuel. Then, the injection pulses are gradually attenuated to form the ordinary injection pulses. Thus, the quantity of fuel can be increased earlier than the increased quantity in the asynchronous injection by the OFF-signal of the conventional idle switch. Therefore, the fuel quantity can be increased at the moment when a car begins to start, and generation of engine stall can be prevented, and starting performance can be improved.

Title: Method and device for controlling brake of step motor using ineffective coil
Inventor: JIEIMUZU NOOMAN JIYAKUSON HOWA
IPC: H02P8/00
Filed: 1982-06-30
Abstract: In a disk drive system which uses as stepper motor, overshooting of the desired final position is reduced by short-circuiting the windings of the stepper motor which normally remain open-circuit or are switched off. This short-circuiting provides a current path for any EMF induced in the unused windings. This effect is achieved by connecting a pair of transistors in parallel with each other and with each respective winding. The transistors are connected in opposite polarity to provide a short-circuit regardless of the polarity of the EMF across the windings. The transistors are connected to a microprocessor which is programmed such that the windings are selectively short circuited and the short circuits are applied at a predetermined time with regard to the step so that 'damping' is optimized. The microprocessor may be programmed to switch the transistors on and off as desired giving flexible timing to suit different conditions. One or more stepper motor steps may be treated in this manner.
