Title: Production of optical directional coupler
Inventor: SASAKI KAZUYA
IPC: G02B6/28
Filed: 1987-06-26
Abstract: PURPOSE:To eliminate the fluctuation in the degree of optical coupling and to prevent the generation of flaws in the optical coupling part by fusing two pieces of optical fibers in a parallel arrayed state and stretching the fused part to a smaller diameter. CONSTITUTION:Two pieces of the optical fibers 1-1, 1-2 having the same structure are arrayed in tight contact with each other and the two points parted by the spacing larger than the coupling length L of the optical coupling part are fixed by using clamping plates 12. The fixed parts of the two fibers 1-1, 1-2 are fused by arc discharging means, etc., to integrate the clad parts of the two optical fibers. While the integrated part is heated by the arc discharge means, etc., tensile force is exerted to the fibers 1-1, 1-2 to stretch the integrated part, by which the cores of the respective fibers 1-1, 1-2 are arrayed in proximity to each other within one small-diameter clad to form the optical coupling part 100. The optical directional coupler produced in such a manner has the specified inter-core spacing of the two optical fibers in the optical coupling part and has no fluctuation in the degree of the optical coupling; in addition, the possibility of flawing the optical coupling part is eliminated.

Title: Gas-liquid contact apparatus
Inventor: FURUTA SHINICHI
IPC: B01F27/94
Filed: 1986-07-08
Abstract: PURPOSE:To obtain the title apparatus enhanced in the dispersion degree of gas bubbles and having high gas-liquid contact efficiency, by constituting the rotary drum, which is arranged so that the axial direction thereof is a vertical axis and has a large number of gas jet orifices provided to the side peripheral surface thereof, provided in a tank body so that the diameter thereof is expanded in the downward direction thereof. CONSTITUTION:Gas is supplied in a rotary drum 18 through a gas supply pipe 28 and a motor 16 is rotated. The gas turns around the communication part 34 of a partition wall 32 to rise between the partition wall 32 and the inner periphery of the drum 18 and is successively injected from nozzles 24. Then, the gas receives shearing action by the rotation of the drum 18 to become fine gas bubbles. At this time, the nozzles 24 come to a state distributed in a horizontal direction because the diameter of the drum 18 is expanded downwardly and gas bubbles are dispersed over a wide range in the horizontal direction. The liquid contacted with the outer periphery of the drum 18 rotating comes to a state turning at a high speed toward the lower part of the drum 18 because the diameter of the drum 18 becomes large toward the lower part thereof. As a result, the gas bubbles injected in a liquid stream go away at a larger speed in the lower part and the dispersion degree of the gas bubbles becomes extremely high.

Title: Image forming device
Inventor: KOMURO ICHIRO
IPC: G03G15/16
Filed: 1996-05-31
Abstract: PROBLEM TO BE SOLVED: To obtain an image forming device hardly causing a deterioration in image quality due to deficiency in a transfer charge. SOLUTION: A photoreceptor 1 is electrified by a scorotron charger as a uniform electrifying means. An electrostatic latent image is formed with image information, on the surface of the photoreceptor 1 and for the electrostatic latent image, toner is stuck to the outside in the width direction of a transfer paper, on the surface of the photoreceptor 1, in accordance with the size of the transfer paper. A toner image formed on the photoreceptor 1 is transferred to the fed transfer paper 6 in a transfer part (nip part) where a dielectric belt is in contact with the photoreceptor 1 and the toner image arriving at a fixing device is fixed. In this transfer, the toner becomes a resistor in the transfer nip part and a current directly flowing into the photoreceptor 1 is suppressed to secure an electric charge required for transferring the toner image.  Therefore, the deterioration in the image quality caused by the size of the transfer paper never occurs.
