摘要： PROBLEM TO BE SOLVED: To obtain a driving circuit of a simple constitution for a physical quantity detecting element capable of accurately compensating for variation due to temperature in the detecting sensitivity of the physical quantity detecting element in which its internal resistance value is increased with rise in temperature and detection sensitivity drops. SOLUTION: The drive circuit to supply a drive current I for the Hall element 16 of a throttle opening sensor is provided with an operational amplifier 2 with an inverting input terminal and output terminal each connected to the drive current terminals (a) and (b) of the device 16 and a non-inverting input terminal connected to the ground potential, a resistance R with one end connected to the inverting input terminal of the operational amplifier 2, an inverting amplifier 3 to invert and amplify the output voltage Vo of the operational amplifier 2, and an adder 4 to add a reference voltage Va (>0) and the output voltage Vb of the inverting amplifier 3 together and to impress it on the opposite-side end part of the resistance R to the side of the operational amplifier 2. In this circuit, when the internal resistance value Rd of the device 16 is increased with rise in temperature, the drive current I is increased to compensate for the sensitivity of the device.

摘要： PROBLEM TO BE SOLVED: To generate flat state in the torque characteristic of a brushless motor. SOLUTION: When the number of poles (number of slots) of a stator is 6 and a number of poles (number of permanent magnets) of a rotor is 8 in a three-phase brushless motor, the coil current of each phase is shifted by a phase at each 12 deg. for electrical angle (mechanical angle of 30 deg.), and also the coil current of each phase is switched in a step state at the same time with three phases by each 60 deg. of electrical angle (mechanical angle of 15 deg.). Here, when I is the coil current for one phase maximized of the three phases, the coil current of the rest of two phases is controlled so as to be -I/2 respectively. In a brushless motor other than the above number of poles, an angle θ switched in a step state of the coil current of each phase is set to 360/N [ deg.] (where, N is the least common multiple of number of poles of stator and rotor) of mechanical angle. In this way, a flat torque characteristic can be obtained over full angle range.

摘要： PROBLEM TO BE SOLVED: To provide a concentration measuring instrument for a liquid capable of excluding the effect of the leak resistance between detection electrodes in measuring the concentration of the liquid.
SOLUTION: The concentration measuring instrument for the liquid includes a first oscillation part 20 and a second oscillation part 25 and switches sw1 and sw2 are changed over by the pulse wave of two different duty ratios d1 and d2. In a case that one switch sw1 is turned on and the other switch sw2 is turned off, an operational amplifier 43 is operated so as to make the potentials of a non-reversal input terminal the same as a reversal input terminal and a detection electrode 41 is charged. Contrarily, in a case that one switch sw1 is turned off and the other switch sw2 is turned on, the detection electrode 41 is grounded on the positive side thereof, so that the charged detection electrode 41 is discharged. The difference based on the output voltages V(d1) and V(d2) of the operational amplifier 43 obtained by the charge and discharge is taken.

摘要： PROBLEM TO BE SOLVED: To certainly determine the trouble of an instrument itself in a measuring instrument for a liquid concentration. SOLUTION: The microcomputer of an alcohol concentration sensor reads the measured value S(f1) corresponding to frequency f1 (S100) and further reads a measured value S(f2) corresponding to frequency f2 (S110), then calculates the difference ¾S(f1)-S(f2)¾ between two measured values (S120). When the difference ¾S(f1)-S(f2)¾ between two measured values is a predetermined value Th or below continues (S130:YES, S140:YES), the microcomputer of the alcohol concentration sensor determines stack abnormality to output a PWM signal of specific frequency different from that of normal time to an engine ECU 300 (S170).

摘要： PROBLEM TO BE SOLVED: To provide a liquid property detecting device precisely measuring concentration by eliminating an influence of a leakage resistance between electrodes in a capacitance type concentration sensor. SOLUTION: A gain of an amplification circuit 40 is not fixed, can be switched, and is increased with a decrease of a voltage Vb being an ethanol concentration detection signal.

摘要： PROBLEM TO BE SOLVED: To provide a wiper control device capable of performing responsive operation to meet the expectation of a driver by reliably changing a wiping mode when a sensitivity adjusting means is operated. SOLUTION: When a sensitivity correction switch 40 is changed, a wiping mode determination unit 51 changes the wiping mode, i.e., the reciprocal wiping operation interval time of a wiper blade 13 is changed so as to meet the sensitivity correction direction by the changing operation of the sensitivity correction switch 40. At the same time, the rain threshold between the wiping modes before and after the changing operation of the sensitivity correction switch 40 is replaced by the rainfall which is the value immediately after a new wiping mode. Thus, the wiping operation of the wiper blade 13 after the changing operation of the sensitivity correction switch 40 can meet the expectation of a driver. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a fuel property sensor capable of preventing unnecessary replacement.SOLUTION: In S105, conductivity between a first electrode and a second electrode in an electrode part is calculated. In S106, whether or not the conductivity is the same as or higher than a predetermined conductivity is determined. In the case the conductivity is the same as or higher than the predetermined conductivity, a temperature characteristics of the conductivity is calculated in S107. In S108, whether or not the conductivity change ratio with respect to the fuel temperature change is the same as or higher than a predetermined change ratio is determined based on the conductivity temperature characteristics calculated in the S107. In the case the conductivity change ratio with respect to the fuel temperature change is determined to be smaller than the predetermined change ratio, a control part determines that an electrode part 65 is abnormal (S109). On the other hand, in the case the conductivity change ratio with respect to the fuel temperature change is determined to be the same as or higher than the predetermined change ratio, the control part determines that the fuel properties are abnormal (S110). Thereby, unnecessary replacement of a fuel property sensor is prevented.

摘要： PROBLEM TO BE SOLVED: To provide a liquid concentration detection device for reducing a concentration detection error. SOLUTION: A capacitance detection means 8 detects the capacitance of a fuel, and a temperature detection means 9 detects a fuel temperature. A concentration detection means 67 detects an ethanol concentration included in the fuel by a detected capacitance detected by the capacitance detection means 8 and a detected temperature detected by the temperature detection means 9. At least either of a capacitance correction means 65 and a temperature correction means 66 corrects the detected capacitance or the detected temperature prior to concentration detection by the concentration detection means 67. Hereby, the concentration detection error is reduced, which is generated by a response delay characteristic which is a delay of a change of the detected temperature to an actual temperature change when a fuel temperature is changed.

摘要： PROBLEM TO BE SOLVED: To provide a shift switching device for preventing an error operation of an actuator caused by the damage to a position detecting switch. SOLUTION: In the limit switch, opening/closing signals of switch contacts SW1, SW2, SW3, and SW4 are outputted to a control device according to switching of 2H-4H-N-4L. The switch contacts SW1 and SW2 detect the position of a slider displaced by a thrust actuator while it is switched from a 4H- engaging region to an N-engaging region, and thereby, it is detected that one of the switch contact SW1 or SW2 is switched between the 4H and N even if the other switch contact SW1 or SW2 is damaged by some reason, and then it is possible to prevent a gear from shifting to N from the 4H. It is thus possible to prevent error operation of the thrust actuator caused by the damage of either one of the switch contact SW1 or SW2, and it is also possible to avoid becoming vehicle control difficult.
