Abstract: PURPOSE:To obtain high output even in an extreme state of an engine under high speed and torque conditions by measuring duration of the extreme state of the engine based on the engine speed and the throttle opening, and gradually increasing and correcting the basic fuel injection quantity based on the duration. CONSTITUTION:When the judgement of misfire based on negative pressure PB continues for a scheduled time, the judgement of misfire is performed based on an indicator pressure PI. When misfire is decided, a PI correction factor (KPI) is set, and the fuel injection quantity TOUT is multiplied by the correction factor KPI to set a new fuel injection quantity TOUT. When misfire is decided by last judgment, a mifire-correction factor (KMF) is set, and the fuel infection quantity TOUT is multiplied by the factor KMF to set a new fuel injection quantity TOUT. Next, when an engine is judged to be in an extreme state under high speed and torque conditions, it is judged whether a scheduled time has elapsed or not. When the scheduled time has elapsed, an extreme state-correction factor (KHIGH) is set, and the fuel injection quantity TOUT is multiplied by the factor KHIGH to set a new fuel injection quantity TOUT. Besides, the extreme state-correction factor KHIGH is changed so as to be gradually increased.

Title: Device for carrying flow of paper sheet which is displaced and stacked
Inventor: HERUMUUTO EMURITSUHI
IPC: B65H5/22
Filed: 1982-09-27
Abstract: A conveyor for sheets fed to or from a printing press in an overlapped stream, the table having longitudinal slots formed therein laterally spaced from one another. A perforated endless conveyor belt is trained over the table. An enclosed chamber extending substantially the length of the table communicates directly with the slots, the chamber being convergently shaped terminating at its lower end in a throat. An axial flow fan in the throat draws air through the perforations so that a stream of overlapped sheets on the belt will be held in contact therewith for transport from one end of the table to the other. The fan is chosen to have a flow characteristic such as to maintain the pressure differential across the fan approximately constant notwithstanding variations in the rate of air flow resulting from gaps in the stream. The belt is in two narrow, laterally spaced sections dimensioned to fit into the slots.

CONSTITUTION:A signal amplifier circuit 10 is connected between a pair of terminals 8 and 9 of the electrode 5 on the side of the gas to be detected of the gas sensor 4 on which the active metal is deposited by evaporation. The active metal reacts and the resistance value of the electrode 5 increases when the active gas G is formed by the generation of electric discharge. Since the output of an operational amplifier 11 increases as well, a transistor 15 turns on and a relay 16 is energized to close a make and break switch 2. The voltage of a constant current power source 1 is consequently impressed between the electrodes 5 and 6 of the sensor 4. The constant current electrolysis of the sensor 4 is thus executed and the amt. of the active gas is measured.

The red corpuscle is treated using a coupling agent to obtain a corpuscle having the coupling agent bonded to the surface thereof and a liquid containing an antirubella virus antibody is brought into contact with the corpuscle thus obtained to create an antirubella virus antibody sensitized corpuscle. The coupling agent employs tannic acid. A rubella virus corpuscle agglutinin (HA) is added to a sample such as human serum or the diluted liquid thereof and then, the antibody sensitized corpuscle is brought into contact with the mixture. If any antibody exists in the sample, agglutination will not occur, where the blocking of corpuscle agglutination is observed.
