An integral plus proportional control system responding to more than one variable controls a single actuator wherein the integral gain is selected in accordance with the error of that variable which is being controlled to compensate for varying process dynamics An error selector serves to discriminate the error signal which is being controlled and synchronously selects the gain of the integrator

PURPOSE:To offer a manufacturing method of an optical fiber handle which is capable of easily obtaining a desired sectional shape in an optical transfer element, and is capable of sending an effective light quantity or image as much as possible in a limited area CONSTITUTION:A photoconductive strand 3 is obtained by making coating glass 2 having a comparatively small refractive index tightly adhere to the circumference of core glass having a large refractive index, and this strand 3 is collected in large quantities, and also is bundled as shown by a code 3' so that it forms a prescribed sectional shape conforming with an object space when it has been elongated Subsequently, an assembly body 5 is obtained by placing an outside circumferential material which can be removed by posttreatment, for instance, a glas rod 4, on its outside circumference, so that the whole sectional shape becomes round The glass rod part 4 of the assembly body 5 is heated and softened under reduced pressure and is made to tightly adhere as one body, by which an outside circumference 4' is formed In this state, the bundle part 3' of the photoconductive strand 3 is heated and elongated until it becomes size conforming with an object space, and after that, the outside circumference 4' is melted out by a dilute NaOH solution In this way, an optical transfer element forming a prescribed sectional shape, that is, a conduit 6 is obtained, and the conduit 6 is incorporated in an endoscope tubular body 7, for instance, as a light guide
