摘要： PURPOSE: To reduce the fluctuation in the discharge pressure of a displacement pump by detecting the discharge pressure of the fluid by a pressure gage provided on the downstream side of a discharge port of the displacement pump, and outputting the pulse train of shorter period when the pressure is lower than the reference value while the pulse train of longer period when the pressure is higher than the reference value to a motor driver. CONSTITUTION: First and second dividing circuits 6, 8 which divide the output pulse train of a reference pulse generator 5 at the dividing ratios a, b and output the divided values, and a third dividing circuit 9 which divides the output pulse train of the second dividing circuit 8 at the dividing ratio (c) and outputs the divided value are provided. A pressure gage 4 is provided on the discharge side of a metering pump 3 to be driven by a motor 2, and the output signal is binarized through a filter circuit 10, an amplifying circuit 11, and a comparative circuit 12, and the output pulse trains of the respective dividing circuits 8, 9 is selected 13 according to the binarized signal. The selected output pulse train is counted by a counting circuit 14, and the dividing ratios b, c are changed 6 by the output where the prescribed number (d) is counted by either of the counting circuits 7, 14.

摘要： PURPOSE:To remove effectively flare light in a light emitting wave length of an LED, and reduce crosstalk when it is arrayed by arranging a dye layer on a side surface so as to absorb light having a specific wave length. CONSTITUTION:In a light transmitting body having a radius (r) and a circular cross section, the refractive index distribution within range of 0.3r to 0.7r has the refractive index distribution almost approximate to a quadratic curve regulated by an expression toward an outer peripheral surface from the center axis. A layer composed of light absorbing dye capable of cutting off effectively light of 630 to 850nm, is arranged on the outer periphery of the light transmitting body having a characteristic value of (1.4 ). It has also a characteristic value of which an MTF value measured by forming a grid image of four line pair/mm on a CCD line sensor through the light transmitting body becomes 70% or more. In the expression, (n0) represents a refractive index of a center axis part of a primary body of the light transmitting body, and n(r) represents a refractive index of a position part of a radius (r) on the center axis side of the primary body of the light transmitting body, and G represents a refractive index distribution constant of the primary body of the light transmitting body, and (r) represents a distance (mm) on the center axis side of the primary body of the light transmitting body.

摘要： PURPOSE:To continuously produce an optical transmitter by combining a polymer with two kinds of monomers. CONSTITUTION:A composite formed by mutually dissolving and mixing a polymer A having a low refraction index N1; a highly volatile monomer C which provides a polymer B having a high refraction index N2; and a monomer E which provides a polymer D having a refraction index N3 higher than the polymer A and is more volatile than the monomer C is put in a cylinder 1. The composite is quantitatively extruded by a piston 4 while it is heated by a heater 3, homogeneously mixed in a kneading part 2, and then extruded by a nozzle to provide a stranded fiber. The stranded fiber is passed through a first volatilizing tower 7a to selectively volatilize the monomer C from the outer circumferential part of the strand fiber 6 under a fixed condition, and then passed through a second volatilizing tower 7b to volatilize also the monomer E, providing a continuous distribution from the surfaces of the monomers C, E in the strand fiber to the center, and the monomer mixture is then polymerized and solidified by an active beam irradiating part 8, and wound on a winding drum 11 through a nip roller 10 to provide an optical transmitter 12.

The surfaces of the transparent cured part are made into the convex shape by the shrinkage on curing of the cured part at this time. The photomask is removed in this state and the entire part of the flat planar resin compsn. is irradiated with the collimated beams of light to cure the uncured matter to a translucent state, by which this plastic lens is obtd.

摘要： PURPOSE:To enhance resolution of a refractive index distribution type rod lens by a simple method by press-bonding a plastic fiber to a rough surface, and transferring the surface to the fiber. CONSTITUTION:A plastic fiber is press-bonded to a rough surface, and the surface is transferred to the fiber to treat an outer periphery of the fiber. A method for transferring the surface to a side of the fiber has a method for rotating a plastic fiber while press-bonding the fiber to a rough surface such as a metal gauze, sandpaper, etc., a method for feeding a plastic fiber in particular object such as sand, etc. When the rough surface is transferred, it is desirable to heat the fiber. More specifically, it is desirable to heat it to 50 deg.C or higher and further desirable to heat it to glass transition temperature (Tg) or higher of the fiber.

摘要： PURPOSE:To obtain a hardened film which is free from defects, such as burrs, on the side faces of an optical transmission body array pinched by plate members and has excellent uniformity by spraying a surface treating agent to the array and curing the agent while rotating the array around its major axis. CONSTITUTION:The surface treating agent 4 of a UV curing type is applied in the form of a mist by a spraying device 2 onto the optical transmission body 1 formed by pinching the optical transmission body array paralleled with distributed index type bar-shaped lenses in the form of an array with two sheets of plate members while the array is rotated around its major axis. This agent is irradiated with UV rays by a UV lamp 6 and is thereby cured. The rotating speed is preferably 5 to 100 rpm and a UV curing type resin, such as crosslinkable photosetting resin, essentially composed of a multifunctional acrylic compd. is used as the surface treating agent 4. Consequently, the hardened film of the film quality having uniform wear resistance is obtd. without generating the burrs projecting from the side faces of the array.

摘要： PURPOSE:To form the rod-shaped photoconductor array sheet which is not disordered efficiently by arranging many short rod-shaped photoconductors made of plastic and joining at least their one-end surfaces together with an adhesive. CONSTITUTION:The rod-shaped photoconductor array is formed by sandwiching a rod-shaped photoconductor array sheet of specific length at a specific position in two array substrates which are applied with an adhesive previously and have rod-shaped photoconductor array grooves, pressing the sheet with both the surfaces of the substrates, and setting the adhesive as specified. Therefore, when the sheet is adhered to the array substrates, no excessive jig is required, so a jig is never stained with an excessive adhesive on the substrates. Consequently, the rod-shaped photoconductor array can be assembled more efficiently and accurately than a conventional method.
