Abstract: PURPOSE:To accurately detect an inclination state through simple constitution by composing an inclination sensor of a permanent magnet which is provided in a case made of a nonmagnetic body having a space internally and can be displaced and a magnetic sensitive element fixed to the case. CONSTITUTION:The inclination sensor consists of the case 1 (including a lid 2) made of the nonmagnetic body having the space 3 internally, the permanent magnet 4 which has magnetic flux stuck on the surface and is stored in the space 3 in a displaceable state, and the magnetic sensing element 6 which senses the magnetism of the magnet 4 fixed to the case 1. Consequently, when the main case 1 is in a horizontal state, the magnet 4 is at the center part of the bottom surface 3 of the space by its own weight. Then when the bottom surface B slants, the magnet 4 moves to the lower part on the bottom surface A. Therefore, the magnet 4 moves away from the element 6 and their relative distance varies; and the magnetism corresponding to the distance is detected and the inclination of the device where the inclination sensor is installed can be detected. Further, the output of the element 6 is used to control the attitude of the device.

Title: Integration circuit
Inventor: KOIZUMI YUJI
IPC: G06G7/186
Filed: 1985-08-01
Abstract: PURPOSE:To secure a long-time constant with a miniaturized integration circuit by having connection between a reverse input terminal of a differential amplifier and the drain of a transistor TR together with the source of the TR connected to the input terminal of said amplifier respectively and providing a TR having an OFF resistance between both input terminals of the differential amplifier. CONSTITUTION:The voltage of a fixed level is supplied to the non-inverse input terminal (+) of a differential amplifier 1 from a power supply 3. A capacitor 2 is connected between the inverse input terminal (-) and an output terminal B. Then the terminal (-) and the source of a TR4 are connected to an input terminal A. The gate voltage (e) is supplied to the gate of the TR4 so that the TR4 is set at a level less than the threshold voltage. Then the time constant of an integration circuit is obtained from the product of the equivalent resistance values of the capacitor 2 and the TR4. The equivalent resistance value of the TR4 is obtained by dividing the potential difference between the terminal A and the terminal (-) by the leakage current of the TR4. This equivalent resistance shows a large value since the leakage current is minute. Thus it is possible to obtain an integrator of simple circuit constitution with a small occupying area.
