Title: Optical isolator
Inventor: MADA JUNJI
IPC: G02B27/28
Filed: 1986-09-20
Abstract: PURPOSE:To prevent quenching from deteriorating by finding variation in wavelength from the attenuation of light intensity when light is transmitted through a Faraday rotator, suppressing a magnetic field so that variation in the angle of rotation by the rotator is suppressed, and making the angle of rotation constant irrespectively of the variation in wavelength. CONSTITUTION:A Bi-substituted garnet film 11 grown on an optical garnet substrate 10 is used. A magnet current control circuit 20 is provided with a function which calculates the wavelength lambda from currents I1 and I2 inputted from detectors 18 and 19 and calculates the rotary angle theta from the relation between the lambda and theta and a circuit which controls a current (i) so that the thetaif deviating from a reference value, i.e. 45 deg. is returned to 45 deg., and the theta is controlled to 45 deg. at any time. The maximum Imax of the relative intensity (intensity after transmission/intensity before transmission) of light which is already passed through an optical isolator to light before the transmission is 1 in a traveling direction when theta is 45 deg. and 0 in the opposite direction when theta is 45 deg.. Consequently, theta is always 45 deg. irrespectively of variation in wavelength and the performance is prevented from deteriorating.

Title: Electromagnetic flowmeter
Inventor: AMINAKA SHIRO
IPC: G01F1/58
Filed: 1989-08-30
Abstract: PURPOSE:To enable an increase of the area of an electrode exposed on the inner surface of a pipe wall without changing the shape of the electrode and thereby to prevent the adverse effect of noise by fitting the electrode non- perpendicularly to the pipe axis of a measuring pipe. CONSTITUTION:An electrode 3 is made non-perpendicular to the pipe axis 2 of a measuring pipe and fitted thereto at an angle (a). This angle (a) can be set to be an arbitrary acute angle, and the shape of the surface of an electrode exposed on the inner surface 1a of a pipe wall is elliptic. When a magnetic field is applied perpendicularly to the measuring pipe 1 and a fluid to be measured is made to flow, an electromotive force being proportional to a measured part is generated in the electrode 3 by a Flemming's left-hand rule and the flow rate of the fluid to be measured is determined from a flow velocity and the cross-sectional area of the measuring pipe 1. The shape of the surface of the electrode exposed on the inner surface 1a is elliptic, on the occasion, and therefore the area being in contact with the fluid is larger than that obtained when the shape is circular. Even when an electric resistance of the fluid is large, therefore, the effect of noise can be prevented, S/N becomes excellent and the precision in measurement is improved.
