Title: Optical scanning potentiometric sensor
Inventor: NAKANISHI TAKESHI
IPC: G01N27/416
Filed: 1995-07-22
Abstract: PROBLEM TO BE SOLVED: To obtain a sensor excellent in resolution and strength by employing a silicon insulator (SOI) substrate as a semiconductor substrate. SOLUTION: An oxide 2 is deposited by about 100nm on the entire surface of a silicon substrate 1 of about 500μm thick and another silicon substrate 3 of 500nm thick is applied tightly thereto before being heated at 1000 deg.C, for example, to form a substrate 4. The substrate 4 is then polished to produce a substrate 1 of 1-2μm thick and an active layer 1A is formed thereon to obtain an SOI substrate 4A. Subsequently, the active layer 1A is etched to leave a part thereof. An oxide is then deposited by about 50nm on the entire surface of active layer 1A and a sensing part of Si3 N4 is formed by CVD. A metal electrode is deposited at the etched part before individual sensors are produced by dicing. A photocurrent generated in the active layer 1A by a light incident on the substrate 3 side can be taken out in the form of a signal from the electrode.  This structure provides high mechanical strength even if the active layer 1A is made thin and the positional resolution can be enhanced through reduction in thickness.

Filed: 1985-09-20
Abstract: PURPOSE:To designate driving coils to excite and to certainly start a rotor magnet by supplying an electric current to reference coils when a driving power source is supplied to the titled device. CONSTITUTION:When the driving power is supplied to the device, the power source voltage is supplied to the reference coils 8 and 9 via a switch circuit 7 and a D.C. magnetic field is generated on the coils 8 and 9.
