Title: Magnetoelectric converter
Inventor: SADAI ZEN
IPC: G01R33/09
Filed: 1991-03-11
Abstract: PURPOSE:To simplify wiring by a construction wherein an MR element prepared by forming a thin-film resistor of a ferromagnetic substance on a substrate and a bias magnetic field impressing means are provided and a magnetic signal in the direction vertical to the substrate is detected. CONSTITUTION:The opposite ends of a thin-film resistor 3 are connected to electrodes 4 and 5 respectively and further to a wiring pattern on a printed circuit board. Besides, magnets 6 and 7 are provided on a substrate 2 so that they holds the thin-film resistor 3 between and that magnetic fluxes coming out of them give a bias magnetic field 8 invariably to the resistor 3. When a magnet 1 is located remote, a signal magnetic field is hardly applied to the resistor 3. Therefore the resistor 3 is affected only by the bias magnetic field 8 and oriented in this direction and an electric resistance becomes lower than the one at the time when no magnetic field is present. When the magnet 1 comes just above the resistor 3, the magnetic flux of the signal magnetic field is impressed in the direction piercing through the resistor 3 vertically, the resistor 3 is thereby put in a state of non-orientation and a resistance value increases. By detecting a change of this electric resistance, the presence or absence of the signal magnetic field can be detected only by providing two wirings.

Abstract: PURPOSE:To make compact the entire device by splitting the outer housing axially into two and arranging a unilateral clutch between any one of the inner or outer housing and an input member. CONSTITUTION:Housing of an outer clutch 12 is splitted into two and a unilateral clutch 23 is arranged between a flange section 17a located at axially inside of clutch boards 16, 19 and an input member, i.e. the boss section 11c of a large reduction gear. Consequently, there is no need to increase the diameter of the clutchboard 16 and thus the outer diameter of a clutch device 10, and since there is a margin between the flange section 17a and the boss section 11c, the diameter of the clutch device 10 can be suppressed. The unilateral clutch may be arranged at the flange section 18a of an inside housing 18, and in this base the flange section 17a of the outside housing 17 is coupled directly with the sideface of the large reduction gear.
