Title: Fuel injection device of engine
Inventor: SUEMATSU TOSHIO
IPC: F02D41/12
Filed: 1984-03-06
Abstract: PURPOSE:To prevent an air-fuel ratio from becoming overrich due to an excess of the quantity of fuel injected during a delay time, by shortening the time of opening of a fuel injection valve during a period when the switching of a driving speed of a fuel pump onto the low-speed side is delayed. CONSTITUTION:In a valve opening means, the number of revolutions of an engine and a load on the engine are detected, a desirable time of opening of a valve is determined therefrom, and the opening of a fuel injection valve is controlled according thereto. In a fuel pump driving speed controlling means, the driving speed of a fuel pump is controlled in accordance with the quantity of fuel consumed by the engine so that it may be high in the case when the quantity of consumption is large and low in the other cases. Moreover, the switching of the speed is delayed for a prescribed time when the driving speed is made to be low. Meanwhile, in a delay detecting means, it is detected whether or not a delay control is executed by the fuel pump driving speed controlling means. In a valve opening time shortening means, the time of opening of the valve controlled by the valve opening means is shortened by a prescribed amount. By this constitution, an increase in the quantity of fuel injected into the engine is prevented, and thereby an air-fuel ratio is prevented from becoming overrich.

IPC: B65H23/18
Filed: 1979-04-10
Abstract: PURPOSE: To run a tape at a constant speed with constant back tension by making a moving member, provided in a cassette, in contact with a magnetic recording tape and by moving it corresponding to the strength of the back tension of the tape.  
     CONSTITUTION: Magnetic tape 64 fixed to reel hubs 14 and 16 at both ends is wound in either direction by way of guide pins 18 and 20, guide roller 22, guide pins 24 and 26, capstan 72, guide pins 28 and 40, guide roller 52, and moving member 50. On the basis of where the moving member keeps balance with back tension and spring 62, the turning angle detector of moving member 50 is set, and as the back tension increases, moving member 50 turns counterclockwise via guide roller 52 against the activation force of spring 62. This rotation is detected by the turning angle detector to reduce a voltage applied to a take-up motor according to the detected angle, thereby lessening the back tension.

Filed: 1983-03-16
Abstract: PURPOSE:To avoid unnecessary calculation for the optimum adjusted value by always monitoring the effective and reactive powers of a generator, and calculating the optimum adjusted value when it is discriminated that the powers are displaced from the effective range of the optimum adjusted value. CONSTITUTION:A discrininating block 2 disriminates whether the present values of the effective and reactive powers obtained from a generator 1 are displaced from the effective ranges of the optimum adjusted value used at present or not, and the optimum adjusted value calculating block 3 calculates the optimum adjusted value when it displaces. When the set values VS, PS of the voltage and power of the generator 1 are altered, whether the optimum adjusted value used at present in a discriminating block 4 is displaced from the effective range or not is discriminated, to calculate the optimum adjusted value. Accordingly, the wasteful calculation can be avoided by eliminating the necessity of always calculating the optimum adjusted value, thereby improving the rapid responsiveness and simplifying the calculator.

Title: Hysteresis erasing circuit
Inventor: SUENAGA HARUO
IPC: G11B5/58
Filed: 1985-03-06
Abstract: PURPOSE:To eliminate the decrease in a life due to hysteresis erasure by applying an increasing or attenuating AC voltage having less distortion, thereby preventing a piezo actuator from resonating. CONSTITUTION:A microprocessor 9 for controlling a magnetic recorder/ reproducer, a BPF 11, an amplifier 12 and a piezo actuator 3 are provided. With this configuration, most of distortion of increasing or attenuating AC voltage is not generated, and since the applying voltage of the actuator 3 is gradually increased or attenuated, the actuator 3 is not resonated. A microprocessor 9 for controlling magnetic recorder/reproducer generates a pulse and applies through a band pass filter 11 and an amplifier 12 to the actuator 3. The increasing or attenuating AC voltage is obtained by constructing to start an oscillation out of the passing band of the BPF 11 and then gradually varying the frequency in the band and further gradually varying out of the band.

Title: Ion beam application apparatus
Inventor: KURODA KATSUHIRO
IPC: H01J37/252
Filed: 1983-03-18
Abstract: PURPOSE:To improve efficiency of the secondary electrons coming from the surface of the specimen to be incident on the detector, by providing a negative electrode to prevent the high positive potential of the lens from reaching the surface of the specimen. CONSTITUTION:While the electrode 2 is grounded, the electrode 3 is applied with the voltage Vd divided from the accelerating voltage Vo. The last lens electrode 4 is applied with a negative voltage Vs to prevent the positive potential from extending toward the vicinity of the surface of the specimen. In the case where a photomultiplier 30 is used as the detector, the secondary electrons generated at the specimen are driven back by the negative potential and all reach the detector by merely applying a low positive voltage Vc to the mesh adjacent the detector, and the detecting efficiency of the detector is thus improved.

Abstract: PURPOSE:To reduce the area ratio of a multicollector, to improve accuracy, to prevent the gain of an open loop from being lowered, and to make an offset hard to be generated in the current of a differential stage transistor by attaching first and second constant current sources on an on-going circuit. CONSTITUTION:A part different from a conventional circuit is a point where the transistors(TM)Q9 and Q10 are connected to a load. In other words, the collectors of the TRs Q9 and Q10 are connected to the bases of TRs Q7 and Q6, respectively, and the bases to a reference voltage source terminal Vref, and the emitters to a negative power source terminal V<->. Then, by setting the area ratio of the TRs Q9 and Q10 so as to set a current 13 equal to a current I4, the currents I1 and I2 become equal, and the offset of the current can be eliminated satisfactorily. Also, by setting the emitter area ratio of the TRs(Q8-Q10) so as to set the currents I1-I4 on the TRs almost equal, the area ratio of the multicollector of the TRs Q3 and Q5 can be reduced to a ratio of 1:1, and the high gain of the open loop can be obtained with high accuracy even when a current amplification factor changes.
