摘要： PROBLEM TO BE SOLVED: To surely remove signal changes, caused by noise components, from the comparison signals of a comparator. SOLUTION: A comparator circuit is equipped with the comparator 20 and a timer circuit 30. The timer circuit 30 outputs output signal V OUT , while inverting it between low level and high level, when the high level is maintained at least over from a first timing and a second timing, after the comparison signal V COMP of the comparator 20 is inverted from low level to high level and is output. The timer circuit 30 has a memory means 38 for storing the fact that the comparison signal V COMP has been inverted from low level to high level with the first timing, when this is confirmed the fact. The memory means 38 cancels the memory state, when the comparison signal V COMP is inverted between the first timing and the second timing. COPYRIGHT: (C)2009,JPO&INPIT

SOLUTION: The positive peak voltage detecting circuit 10 is equipped with a comparator 20, a counter circuit 40, a D/A conversion circuit 50, a first clock signal generating circuit, and a second clock signal generating circuit.

摘要： PROBLEM TO BE SOLVED: To provide a signal processor for a physical quantity sensor which can reduce the number of adjustment terminal for use in adjustment exclusively.
SOLUTION: The signal processor, in the normal state in which the pattern of a sensor signal output from a sensor element is a sensor mode, determines whether or not it is a predetermined pattern which is not output from the sensor element (S105). When it is determined that the pattern of the sensor signal is the predetermined pattern (S105; trim mode), an operation mode other than the sensor mode, such as the trim mode, is switched to the trim mode, allowing a trimming data control section to set trimming data. The signal processor can be thereby switched from the sensor mode to the trim mode without using the adjustment terminal or the like to set the trimming data by inputting a sensor signal corresponding to the predetermined pattern through the sensor element.

摘要： PROBLEM TO BE SOLVED: To provide a signal processing circuit for a rotation detecting device, which detect rotational position of a gear teeth-formed rotor with a higher degree of accuracy. SOLUTION: During rotation to normal rotating direction of the rotor, main sensor signal variation caused by top side edge of peak section is defined as valid edge-based signal variation, while signal variation caused by rear side edge of peak section as invalid edge-based signal variation. Similarly in rotation to reversal rotating direction, signal variation caused by rear side edge of peak section is defined as valid edge-based signal variation, while signal variation caused by top side edge of peak section as invalid edge-based signal variation. Detected signal generation circuit 10 generates the detected signal in which falling edge variation arises depending on the valid edge-based signal variation of main sensor signal or rising edge variation arises depending on the invalid edge-based signal variation, regardless of rotating direction of the rotor. Even if the rotor has changed rotating direction, detection error of the gear teeth can be prevented by inhibiting the occurrence of falling edge variation in the detected signal depending on the first valid edge-based signal variation of main sensor signal.

解决方案：旋转到转子正常旋转方向时，由主峰传感器信号变化引起的峰值段边缘的主传感器信号变化被定义为有效的边沿信号变化，峰值段后边缘引起的信号变化无效基于边缘的信号变化。类似地，在旋转到反转方向时，由峰部分的后边缘引起的信号变化被定义为有效的基于边缘的信号变化，而由峰值段的顶侧边缘引起的信号变化作为无效的基于边缘的信号变化。检测信号生成电路10根据主传感器信号的有效边沿信号变化产生下降沿变化的检测信号，或者基于无效边沿信号变化而产生的上升沿变化，与转子的旋转方向无关。即使转子已经改变了旋转方向，也可以通过根据主传感器信号的第一有效基于边缘的信号变化来抑制检测信号中的下降沿变化的发生来防止齿轮齿的检测误差。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To output a detection signal capable of detecting rotational movement of a rotor, even when the rotational movement is produced so as to repeatedly switch the rotating direction of the rotor, by a short cycle. SOLUTION: For example, when a change in a main sensor signal is an effective edge when a rotational direction of the rotor is switched from a forward rotational direction to a reverse rotational direction during an output of a forward rotation pulse, the output request signal for a reverse rotation pulse generated by the effective edge is retained by a reverse rotation output request signal retaining circuit 28. After completion of the output of the forward rotation pulse, the reverse rotation pulse is output, on the basis of a retained output request signal. However, when the output request signal of the reverse rotation pulse and a request signal of the forward rotation pulse are generated by switching the rotational direction of the rotor, in the order of forward rotation/reverse rotation/forward rotation by even number of times during an output of the forward rotation pulse, both the outputs of the forward rotation pulse and the reverse rotation pulse based on the request signals are set so as not to be carried out.

摘要： PROBLEM TO BE SOLVED: To sense abnormality of a reverse rotation signal output system for a crank angle sensor with a reverse rotation detection sensing function for outputting a reverse rotation pulse signal at the time the engine rotation direction is reversed.
SOLUTION: The crank angle sensor 34 commands output of an abnormality diagnosing pulse signal from a reverse rotation signal output system according to judgment by an abnormality diagnosing signal command circuit 46 in a predetermined period during cranking (such as a period until a forward rotation pulse signal is output for predetermined times) immediately after judgment that the power source of a crank angle sensor 34 is switched on (ignition switch is on) by a power source-on sensing circuit 45 as an abnormality diagnosing period so as to output a main pulse signal to a reverse rotation judging circuit 40. An ECU 36 judges whether or not the abnormality diagnosing pulse signal is output normally from the reverse rotation signal output system of the crank angle sensor 34 in the abnormality diagnosing period. In the case the abnormality diagnosing pulse signal is not output normally, it is judged that the reverse rotation signal output system of the crank angle sensor 34 suffers abnormality.
