Title: Method for detecting attaching direction of light magnetic field sensor using permanent magnet
Inventor: TANAHARA MAMORU
IPC: G01R15/20
Filed: 1992-08-18
Abstract: PURPOSE:To easily check the attaching direction of a light magnetic field sensor at the time when a plurality of points of current and magnetic fields are measured with the light magnetic field sensor. CONSTITUTION:Within a light magnetic field sensor 1, light transmitted from an emission part 4 is modulated by an outside magnetic field and received by a light receiving part 5. A light signal received by the light receiving part 5 is converted into an electric signal within a photoelectric convertor 3 and the electric signal is observed with a waveform observing device 11. When the attaching direction of the light magnetic field sensor 1 is checked, a permanent magnet 10 and the light magnetic field sensor 1 are suddenly separated from each other after an N-pole or an S-pole of the permanent magnet 10 is made suddenly to approch the light magnetic field sensor 1 or the N-pole or the S-pole of the permanent magnet 10 is made slowly to approch there. Since a waveform different in a variable direction is shown on a waveform observing device 11 in response to the direction of an optical path within the light magnetic field sensor 1, the waveform on the waveform observing device 11 is observed for the purpose of discrimination of the attaching direction of the light magnetic field sensor.

Abstract: PROBLEM TO BE SOLVED: To prevent the damage of an opening/closing cover or the periphery by providing the buffer means of resin board and the like having a structure which bends when it received operation force for a remote controller and absorbing or attenuating operation force just before the opening of an opening/closing valve completes. SOLUTION: The opening/closing cover is opened for using the operation switch 10 of a remote controller main body. The opening/closing cover rotates by gravity with a fulcrum as a center and drops toward a wall face. In the buffer means, the resin board 13 having structure which bends by receiving gravity is provided on the lower side of the outer frame of the operation switch 10 in the remote controller main body.

The flexible margin 15 of the resin board 13 is previously calculated and obtained.  When the opening/closing cover is opened, the gravity of the opening/closing cover is added to the projection part 14 being the power point and the resin board 13 bends between the fulcrums. It absorbs or buffers dropped operation force and it reduces it before it collides with the wall face. Thus, the controller is prevented from being strongly collided with the wall surface.
