Title: Adaptive controller
Inventor: KANDA MASAE
IPC: G05B13/02
Filed: 1989-02-23
Abstract: PURPOSE:To turn the deteriorated state of a control system into its original stable state in a short time by monitoring always the state of the control system including a control subject and selecting and carrying out the optimum control including the change of a control constant in accordance with the state of the control system. CONSTITUTION:An identifying signal generating part 8 applies an identifying signal Vu to an adder 6 with input of a start command. An identifying part 9 receives a manipulated variable (MV + Vu) including the signal Vu and a controlled variable PV received from a control subject 3 applied with the variable (MV + Vu). Then the part 9 samples the variable PV in a fixed cycle and estimates the dynamic characteristics P(S) of the subject 3 from the sampling data via an RLS or UD resolving filter. A converting part 10 converts a model of the estimated characteristics P(S) into a model of a frequency function. A designing part 11 calculates a control constant including a P arithmetic coefficient, etc., to the model of the frequency function via a partial model matching process applied in a frequency range and sets the coefficient to a control part 4.

Title: Cowling of outboard motor
Inventor: ISOGAWA ATSUSHI
IPC: F02B61/04
Filed: 1990-02-23
Abstract: PURPOSE:To prevent the noise generated by an engine and the noise generated when air is taken into a cowling from spreading to the passengers of a ship by providing a thick wall which is thicker than other sections at a part including at least the front part of a top cowl wall face and by suppressing the increase in weight of an outboard motor as much as possible. CONSTITUTION:A top cowl 38 has a shape of a box whose lower section is opened as a whole, and a part of the wall faces includes at least the front face 46 and is formed so as to be thicker than the other wall faces. In this case, the front face 46, the front side of the top panel 48, and the front parts of both sides 50 are thick parts. In this case, the transmission of the sound from an engine 10 and air-intake sound introduced from an air-intake port 44 to the inside of a cowling is prevented in the tick parts and effectively shut off. In addition, even if the vibration of the engine 10 is transmitted to the top cowl 38, because the rigidity of the thick parts is high, the vibration of the thick parts is limited, and the generation of noise is restricted. Since the passengers stay in the ship, that is, are positioned at the front part of the ship far from the outboard motor, noise is effectively prevented from spreading.

Title: Control system of engine
Inventor: NAKAMURA RIYUUICHI
IPC: F02D41/22
Filed: 1984-03-08
Abstract: PURPOSE:To prevent much deterioration of the performance of an engine, by providing a circuit generating a pulse output S3 having a pulse width proportional to Q/N, and by controlling fuel injection by means of the aforesaid pulse generating circuit on the occasion of the failure of a processor. CONSTITUTION:A frequency halving circuit halves a crank angle signal S1 and generates an output S4 being at H level in the first half and at L level in the second half. An input of a cycle-voltage converting circuit is an output S2 of a Karman vortex flow meter, and the cycle of this output is converted into a voltage by this circuit. The pulse width of an output S3 of an AND gate 20 is proportional to the cycle of the crank angle signal S1 and inversely proportional to the cycle of the output S2 of the Karman vortex flow meter, in other words, it is proportional to Q/N. When said output S3 is used as a fuel injection control signal, an engine can be operated with characteristics not inferior to those displayed when a processor is normal, and thus an emergency averting running can be conducted. An abnormality of the proccessor may be determined by a processor peripheral circuit, and based on this determination, a fuel injection control system may be switched from the processor to this circuit.

Title: Interruption of fuel supply for electronically controlled engine
Inventor: OONISHI AKITO
IPC: F02D41/12
Filed: 1982-03-23
Abstract: PURPOSE:To enable ample increase of the period for interruption of fuel supply by varying the revolutions in the finishing of the interruption according to the deceleration in the supply of fuel to the internal combustion engine with a proper cutting of fuel at the deceleration. CONSTITUTION:At the step 46, it is determined whether the fuel supply is interrupted or not. Checking is also done to see if the revolutions of the engine are above 1,000r.p.m. during the interruption. When they are not, the interruption continues. The deceleration DELTAN of the engine rotation is judged at the step 48 and when it exceeds a specified value, the revolutions of the engine in the finishing of the interruption are set at 900r.p.m. As the implementation of the step 49 shows that the total of the quantity of fuel in the non-synchronous injection and that in the initial synchronous injection of the end of fuel interruption is above the quantity of fuel required for the explosion, explosion takes place at the initial one rotation after the end of the fuel interruption. Thus, the period for implementation of the fuel interruption can be increased amply.

Title: Reactive power computing element for rectifier
Inventor: KONISHI SHIGEO
IPC: H02M7/155
Filed: 1990-02-26
Abstract: PURPOSE:To calculate ineffective power without delay time and to securely compensate the reactive power to be fluctuated corresponding to a load, which is fluctuated at high speed, by generating a pulse signal when a rectifier is commutated and calculating the reactive power corresponding to a commutation time point to be detected. CONSTITUTION:A commutating time pulse generating means 1 detects the commutation time point when the rectifier is commutated, a direct current detecting means generates an electric signal proportional to the direct current of the rectifier and a delay voltage generating means 31 generates a delay voltage signal delayed by a designated phase angle to the voltages of respective phases. In such a case, the value of the delay phase angle for the delay voltage signal is set to a value suitable for calculating the reactive power corresponding to the commutation time point to be detected. Further, a sample - hold circuit 33 samples the momentaneous value of the delay voltage at the commutation time point and when the value and the output signal of the direct current detecting means 21 are multiplied by a multiplier 34, the output signal of the multiplier 34 becomes the electric signal proportional to the momentaneous value of the ineffective power for each phase. Thus, the ineffective power can be controlled separately for each phase at high speed and in respect to a power system to which the rectifier is connected, the rapid voltage fluctuation caused by the reactive power can be suppressed.

Filed: 1991-03-11
Abstract: PURPOSE:To surely prevent generation of an overrich phenomenon of air-fuel ratio due to a purge of vaporized fuel by limiting a supply amount of fuel to an engine to a decreasing side when a control valve, which opens/closes a purge passage, is detected in a conduction condition at the time of starting the engine.
