Title: Detecting circuit or disconnection of temperature sensor
Inventor: KOJIMA TOSHIYUKI
IPC: G01K7/02
Filed: 1990-03-26
Abstract: PURPOSE:To detect a disconnection immediately after electricity is supplied from a high potential power source by quickly charging a noise absorbing capacitor through a switching device in the ON state when the high potential power source is turned ON. CONSTITUTION:An analog switch SW as a switching device has one end connected to a high potential power source Vcc2 and the other end connected to a noise absorbing capacitor C1. When the power sources Vcc1, Vcc2 are turned On while the capacitor C1 is not charged, the capacitor C1 is quickly charged through the switch SW in the ON state. When the quick charging is finished, the capacitor C1 comes not to be charged through the switch SW which is turned into the OFF state. Therefore, when a temperature detecting output is fed from a temperature sensor SS with the power sources Vcc1, Vcc2 turned ON, electric noises included in the output are absorbed by the capacitor C1. Accordingly, it is possible to detect a disconnection without being influenced by the electric noises.

Title: Magnetic rotation detector
Inventor: SAKAKIBARA MASAHIKO
IPC: G01B7/00
Filed: 1986-04-04
Abstract: PURPOSE:To restrain changes in amplitude and achieve a high resolution due to waveform processing by arranging a magnetic sensor relative to a magnetic drum so that the longitudinal directions of a plurality of stripe-like MR elements are parallel to the rotating direction of the magnetic drum. CONSTITUTION:A magnetic signal track 12 alternately has magnetized portions and nonmagnetized portions. Since there is no magnetic leak from the magnetized portions to the nonmagnetized portions because the magnetization directions of the magnetized portions are parallel to the shaft center of a magnetic drum, the longitudinal directions of MR elements are parallel to the rotating direction of the magnetic drum 1, namely, the proceeding direction of the magnetic signal track 12 and the lengths of the MR elements in their longitudinal directions are approximately equal to those of the magnetized portions or the nonmagnetized portions, when the magnetic drum 1 rotates, following three conditions are repeated: (a) magnetic fields act on the overall lengths of the MR elements in their longitudinal directions; (b) the magnetic fields act on part of the MR elements in their longitudinal directions and do not act on the remaining part; (c) the magnetic fields do not act on the overall lengths of the MR elements in their longitudinal directions. Since changes in the resistances of the MR elements represents a triangular wave in the above-described conditions, changes in amplitude can be restrained even though a spacing changes.
