Title: Signal peak detection device
Inventor: TAKANO YASUHIRO
IPC: G06N3/00
Filed: 1993-09-28
Abstract: PURPOSE:To improve the accuracy of detecting a peak by using a neural network and then judging the pressure or absence of peak in the frequency spectrum of input signal. CONSTITUTION:A signal processing part 21 performs a high-speed Fourier transformation of the output signal of a sensor 20 to convert it into a frequency spectrum. A characteristic extraction part 22 detects the peak of spectrum after the conversion to examine the peak height. A judgement part 23 of classification judges whether the detected peak is higher than a certain threshold level or not. The neural network in the judgement part 23 can be constituted by hierarchical network with, for example, 1024 input layers, 60 intermediate layers, and 1 output layer. When the presence or absence of peak can be judged by such a neural network, the judgement result can be displayed by a result display part 24.

Title: Capacitive dynamic quantity sensor
Inventor: HANZAWA KEIJI
IPC: G01R31/12
Filed: 1998-08-26
Abstract: PROBLEM TO BE SOLVED: To stably and linearly convert the dynamic displacement detected by means of a capacitive sensor into a voltage (DC output) without being subject to the influence of a stray capacitance by using a driving frequency for high- speed detection without being restricted by the responsiveness of an operational amplifier. SOLUTION: When a capacitance element 5 (Cs) for detecting dynamic quantity is displaced in proportion to a dynamic quantity, the balance between the amount of charges in the element 5 and the that of charges in another capacitance element 4 for reference is destroyed and a difference occurs between the amounts. When the difference occurs, the output Vout of an operational amplifier 7 changes in proportion to the difference, but the output Vout finally stabilizes at the point at which the amounts of charges in the elements 5 and 4 become equal to each other. The output Vout is proportional to the inverse number of the capacitance Cs of the element 5 and takes the form of a DC voltage. In addition, such an output that does not rely upon an integrated feedback capacitance (feedback capacitor) CF can be obtained.

Title: Driving circuit for magnetic sensor circuit
Inventor: SHIMIZU SHINKICHI
IPC: G01B7/00
Filed: 1989-09-19
Abstract: PURPOSE:To improve the measurement accuracy of a sensor by employing a voltage dividing circuit as a temperature compensating circuit to vary a sensor current with temperature, and thus making a sensor voltage constant. CONSTITUTION:A resistance 3 detects and feeds the sensor current Is back to an integration circuit 22 negatively and an amplifying circuit 4 which amplifies the output voltage Vs of a magnetic sensor circuit 1 to generate an output voltage VOUT. The sensor current Is is fed back to the integration circuit 22 negatively, so the voltage at an output node N2 of the integration circuit 22 has a value corresponding to the voltage at a node N1. Namely, when the voltage at the node N1 is constant, the sensor current Is becomes constant and when the voltage at the node N1 varies to the contrary, the sensor current Is also varies. Even when the temperature varies, temperature compensation is so performed that the output voltage Vs of the magnetic sensor circuit 1 does not vary. Namely, when the temperature varies, the resistance value of the temperature compensating resistance RH of the voltage dividing circuit 21 varies and the sensor current Is varies to perform temperature compensation so that the sensor output voltage Vs becomes constant.
