Abstract: A control device of a lean-burn engine has an electronic control unit. Upon start of switching from stoichiometric driving to lean driving, the control unit (10) derives, from a map, a target pressure (P0) and a basic opening degree (D0) of an idling speed control valve, serving as an air bypass valve, based on the throttle opening degree (TPS) and the engine rotation speed (Ne) at the start of the switching. The control unit supplies driving pulses (N) of a number corresponding to the basic opening degree (D0) to a stepper motor (32) of the idling speed control valve. Then, the control unit supplies the stepper motor with driving pulses of a number corresponding to an opening degree correction amount (D1) which in turn corresponds to a deviation between the target intake pressure (P0) and an actual intake pressure (PB), to thereby suppress a change in the torque at the time of switching between the rich driving, including the stoichiometric driving, and the lean driving of the lean-burn engine.

Abstract: A fuzzy logic control device is used in conjunction with a pair of coaxially aligned and independently controlled paper feed rollers and a paper skew detector to detect and correct skew in a conveyed paper in a paper feeding device.

Abstract: A paper let-out apparatus is provided which includes a paper accommodating section for holding paper, such as bills, on a bottom plate such that the paper is inclined slightly from vertically standing state. The apparatus includes a fixed receivng plate and a pushing member for urging accommodated paper toward the receiving plate. The receiving plate is formed with a window, and a let-out roller is provided outside the paper accommodating section so that the roller faces the window. A friction member is provided to the let-out roller at a portion of the periphery thereof such that the friction member projects outwardly radially beyond the periphery thereof. As the let-out roller is driven to rotate, the friction member enters the paper accommodating section through the window to be in contact with the endmost or first paper sheet thereby letting out the same due to frictional force.

Abstract: A checkin gate apparatus comprises a carry-in path for carrying in a ticket inserted into an insertion slot; a reader section disposed in the course of the carry-in path to read information recorded on the inserted ticket; a ticket cutter device for cutting off the ticket into two half stubs after the reader section has read recorded information; a switchable carry path for distributing the two cut-off ticket stubs into a collection direction and a discharge direction; a collection path for collecting one of the two stubs of the ticket; and a carry-out path for carrying out the other of the two stubs of the ticket to a discharge slot. In particular, all the above-mentioned sections are housed within a movable or portable casing provided with casters and/or a handle.
