Title: Idling speed control method for engine
Inventor: KASHIWATANI MINEO
IPC: F02D41/00
Filed: 1988-12-16
Abstract: PURPOSE:To prevent the overshooting by detecting idling state, starting the feedback control for the bypass valve duty when the engine speed is reduced the value higher than the target speed by the specified value. CONSTITUTION:When detecting the idling state at the time of the input of the signal from an idle switch, an electronic controller circuit 64 sends a duty value to a bypass valve 62 and makes the feedback control to control the engine speed to the target idling speed, however, if the engine speed is directly reduced to the idling speed, the overshooting effect may be developed. To avoid this, the electronic controller circuit 64 makes direct feedback control even if detecting the idling state, and starts said control when the engine speed is reduced to the value higher than the target value by the specified value (e.g., 400r.p.m.). Thus the engine speed at the idling time may be controlled precisely to the target value without overshooting the engine speed.

Title: Sheet sheaf binding device and sheet treatment device
Inventor: HIRAI KATSUAKI
IPC: B42B4/00
Filed: 1996-11-29
Abstract: PROBLEM TO BE SOLVED: To hold the binding range of a stapler to a specified range by differentiating stop control of a driving part according to driving time from the start of the driving time until the detection of a detecting time during initial action when a binding range formed of a driver part and an anvil part is made a maximum range. SOLUTION: In case of a sensor S1 being ON, a motor M1 is stopped after one normal driving action to prevent overrun and to hold a stapler to a specified range. In case of the sensor S1 being OFF, an action timer is started simultaneously with the start of the motor M1 so as to clock time until the sensor S1 is turned ON. In case of being within the specified time, the motor M1 is stopped after the lapse of the specified time, and in case of being the specified time or more, the motor M1 is stopped immediately. That is, during initial action after the disposal of a stable jam or the like, the motor M1 is controlled to stop after driving the overrun part of a stapler during normal use even in case of the sensor S1 being OFF. The stapler can therefore be held to a specified binding range.
