Title: Sorting method of film resistance heat generating body for level sensor
Inventor: KITSUKAWA KANEHISA
IPC: G01F23/22
Filed: 1990-05-10
Abstract: PURPOSE:To sort film resistance heat generating bodies into ranks by setting a high and a low temperature ambiences, and obtaining a resistance value when a current approximately equal to the using current is allowed to flow in the ambiences. CONSTITUTION:A current source 10 and a voltmeter 11 are controlled by a computer CPU. The current source 10 is connected to the voltmeter 11 via a synchronizing signal line. While a sample (p) is put in a thermostatic chamber 12, an instruction is ordered for the current source 10 to generate a current expected to run in both the high temperature ambience and the low temperature ambience. The current source 10 generates the instructed current, with sending a signal to the voltmeter 11. When the voltmeter 11 receives the signal, it measures the voltage generated at both ends of the sample (p) after a predetermined delay time. The voltage and current are recorded by the computer CPU, so that the resistance of the sample (p) is calculated. Accordingly, it becomes possible to select and sort the samples (p) into ranks in accordance with the using condition while the current dependency of the resistance value is taken into consideration.

IPC: G01F1/698
Filed: 1978-10-04
Abstract: PURPOSE: To avoid lowering of the operation velocity with a simple constitution by supplying the output given from the air flow meter to the signal process circuit after smoothing.  
     CONSTITUTION: Output signal 23 given from the hot-wire type air flow sensor is transmitted to signal process circuit 7 via smoothing circuit 10. The signals are led into circuit 7 from clock generation circuit 9, distributor sensor 11 and crank angle sensor 14 each, and the output waveform of the hot-wire sensor is changed into nearly the linear form via circuit 10. Thus in case circuit 9 is used, the signal processing becomes possible by generating the clock signals with the time duration of a fixed interval and also taking in the smoothed signals. Furthermore, the pulsation waveform of the hot wire is led to circuit directly, and the peak and bottom value of the waveform are detected by peak detector 15. And based on these two value, the mean air flow velocity can be calculated. In this way, the lowering of the operation velocity can be avoided easily.
