Title: Waveguide type optoacoustic spectrum analyzer
Inventor: NISHIMOTO YUTAKA
IPC: G02F1/1339
Filed: 1986-02-22
Abstract: PURPOSE:To widen a dynamic range with a simple constitution by separating undeflected light which is not deflected with a surface acoustic wave and deflected light which is a signal component spatially in a plane optical waveguide and removing the undeflected light from the plane waveguide. CONSTITUTION:Light emitted by a light source 12 is guided to a three- dimensional waveguide 11 provided on the surface of a substrate and then propagated in the waveguide and the plane waveguide 13. The light 23 propagated in the waveguide 13 has an angle of deflection determined almost by the wavelength of the light source, the beam width of light propagated in the waveguide 1, and the refractive index of the waveguide 13, and the light 23 is considered almost as collimated light in an area where the angle of deflection is small. This light 23 is deflected with the surface acoustic wave 19 generated by an electrode 18 for surface acoustic wave generation and separated into the deflected light 16 and undeflected light 17 spatially in the waveguide 13. Then, the undeflected light 17 is removed from the waveguide 13 by a reflecting or absorbing material and only the deflected light 14 is converged by a plane lens 14 and detected by an array detector 20.

Abstract: PROBLEM TO BE SOLVED: To uniformize the quality of the extruded product of a multi- component extruder by adjusting the number of rotations of each individual extruder in matching relation to the measured values of pressure and temp. from the values of nominal pressure and temp. of each individual extruder. SOLUTION: A hopper is loaded with a material and the extrusion screws 8 of individual extruders 2-4 are adjusted to a predetermined nominal number of rotations by a control and adjusting unit 27. The product introduced into an injection head 5 is taken out by a taking-over roll 24 and the width thereof is measured by cameras 25, 26. The control and adjusting unit 27 calculates a total material flow and a total mold material in a width measuring region on the basis of the calculated width as the standard of the vols. and taking-over speeds of indivisual components.  When the width of the individual component of the total mold material is shifted from an averaged predetermined pressure value so as to exceed a predetermined tolerance range, the control and adjusting unit 27 changes the number of rotations of each extruder corresponding to the average shift of pressure and temp. from the corresponding nominal values. The number of rotations is continuously changed by always measuring the width by the cameras 25, 26.
