Title: Driving method of semiconductor pressure sensor
Inventor: OKADA KAZUHIRO
IPC: G01L9/06
Filed: 1984-09-25
Abstract: PURPOSE:To make the effect of fluctuation in current conduction as small as possible, by applying a pulse current, whose amplitude is larger than that of a rated current, to gage resistors formed in a semiconductor diaphragm when a power source is turned ON. CONSTITUTION:Gage resistors 3a-3d are formed in a semiconductor diaphragm. A bridge circuit BR is constituted of the resistors 3a-3d.

The resistors 3a-3d are heated, and the temperature of the entire diaphragm is quickly increased to a specified temperature. When the charging of the C15 is finished, a rated current I is supplied to the circuit BR through a constant current circuit 14. Thus the effect of the fluctuation in current conduction can be made as small as possible with respect to the output of a sensor at output terminals 6a and 6b.

Thereafter, in this manner, the beam 16 reaches a mirror 12n. A splitter 18a expands the beam 16 to a fan beam 22 to be emitted to detector sections 24a-24n. After penetrating an area 10 to be measured, the beam 22 enters into the detector sections 24a-24n. As the beam 22 enters a beam splitter gets incident, it 22 is partially divided with the beam splitter to enter into a photo sensor. With the photo sensor, the beam is converted into an electrical signal and amplified to be stored into a memory. Thus, a tomographic image, the type and density of a pollutant and the like are printed out with a CPU, thereby enabling immediate detection of the condition of pollution.
