PURPOSE:To improve conversion accuracy and to improve explosion proof property, environment resistance and the like, by coupling a controller part, which converts an input signal into a light signal, and a converter part, which feeds back an operating amount after it is converted into light, by a piece of optical fiber. CONSTITUTION:A controller part 2, which has a control and operation part 30, a light emitting part 40 and a light receiving part 50, is coupled with a converter part 3 by a piece of optical fiber 4. The converter part 3 is composed of a light to air pressure converter part 60 and an air pressure to light converter part 70. At an opening part of one end of a hollow optical fiber 61 in the converter part 60, a flapper 64 is provided. A hollow part is made to be an air path of supplied air. The inside of the wall is made to be the light path of a light signal. The change in back pressure of the supplied air due to the deformation of the flapper is taken out as the output air pressure. The light signal from the light emitting part 40 is converted into the output air pressure by the converter part 60. The pressure is used as an operating force. The operating amount is converted into light by the converter part 70. After the conversion, the amount is fed back to the light receiving part 50. The difference between a signal S2, which is proportional to the output air pressure from the converter part 3 and received by the light receiving part 50, and an input signal S1 is detected. The control operation part 30 is performed. Thus the feed-back system is constituted.

77	MOVING BODY DETECTOR	JP10030881	1981-06-26	JPS5832110A	1983-02-25	SUZUKI MASATOSHI
PURPOSE:To detect a moving body and to discriminate its shape on real-time basis through a moving body detector, by using a video signal from a TV camera and a spatial filter function and calculating the spatial function of a video pattern. CONSTITUTION:A video signal A of an object A from a TV camera 1 is denoted as f(x,y). A control circuit 2 controls the camera by a horizontal and a vertical synchronizing signal and also sends a vertical address signal B and a horizontal address signal C to an RAM3 synchronously with said synchronizing signals. The spatial function S of a video pattern is found from sf(x.y)F(x.y)dxdy where F is a spatial filter function, so the value of said F at a corresponding picture element (x,y) is stored in an RAM previously and multiplication 5 and integration 6 are performed to find the spatial function S. Then, a CPU4 detects a moving body, discriminates its shape and detects its speed.

An exterior gauge component is used to indicate a tank liquid level based on a rotational orientation of a tank magnet at a gauge head. The exterior gauge component includes a multi-track rotary encoder wheel and an optical sensor configured for reading an output of the multi-track rotary encoder wheel. The multi-track rotary encoder wheel is configured to rotate with rotation of the tank magnet such that specific ranges of rotational orientation of the tank magnet each corresponds to a specific output of the multi-track rotary encoder wheel. Each track represents a binary bit of the output read by the optical sensor. An adapter plate mounts a housing of the exterior gauge component to the gauge head and has an opening therethrough. A proximal end portion of the housing including magnets extends through the opening, and is detachable from the housing and attachable to a threaded adapter for mounting to a threaded opening of a tank.
