Title: Electrostatic capacity type pressure sensor
Inventor: MIURA KIYOSHI
IPC: G01L9/12
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To detect an introduced pressure accurately by forming a cavity having a gap in a sensor chip with an electrode and a diaphragm which is deformed according to pressure and by making the diaphragm symmetrical in its changing direction. SOLUTION: A sensor chip 32 consists of substrates 12 and 31, which are opposited to each other and joined together in such a state that an electrode 16 and a diaphragm part 33 which is deformed according to pressure may form a cavity part 14 having a gap. The diaphragm part 33 is made symmetrical in its changing direction. When a pressure to be measured is applied to the diaphragm part 33, the gap in the cavity part 14 is changed depending on a difference between the applied pressure and pressure within the cavity part 14, and an electrostatic capacity in the cavity part 14 is also changed as a result. Since introduced pressure and gap width are correlated with each other, the pressure to be measured can be detected by measuring the electrostatic capacity in the cavity part 14.  Further, the diaphragm part 33 is made symmetrical in the changing direction, so that no difference of sensitivity output occurs value by positive or negative introduced pressure.

IPC: H04B10/00
Filed: 1985-09-06
Abstract: PURPOSE:To attain a high-definition transmission by providing a low cut filter that eliminates an analog signal component at a digital signal receiving link which takes out a receiving digital signal from a directional coupler on one side and a high cut filter that eliminates a digital signal component at an analog signal receiving link which takes out a receiving analog signal from the directional coupler on the other side. CONSTITUTION:When an isolation in a light branch coupler 11a on one side is incomplete, a part of transmitting analog signal inputted to the analog signal receiving link is leaked to the digital signal receiving link side. However, at the digital signal receiving link, a leaked analog signal is eliminated by the function of a low cut filter 19 consisting of a light/electric converter 13a. The malfunction of a reception due to the leakage of an analog signal can be prevented. Also, when the isolation in a light branch coupler 11b on the other side is incomplete, the error of the reception is prevented since, at the analog signal receiving link, a leaked digital signal is eliminated by the function of a high cut filter 22 consisting of a light/electric converter 13b.
