    摘要: This invention relates to a method for the treatment of a desulfurization absorbing fluid after gas-liquid contact with combustion exhaust gas in which fine particles of unburned carbon and other materials are efficiently removed from the desulfurization absorbing fluid to improve the quality of a by-product (e.g., gypsum) obtained therefrom. The method of this invention comprises the steps of feeding a gas into a desulfurization absorbing fluid (A) containing fine particles of unburned carbon and other materials and thereby producing gas bubbles so as to cause the fine particles to adhere to the surfaces of the gas bubbles and create a foam phase (D) consisting of the gas bubbles; and breaking the foam phase (D) to obtain a liquid (E) containing the fine particles.

    摘要: A shoe press belt for the shoe press of a paper making machine includes first and second resin layers and a base layer. Resin is coated and cured on the polished surface of a cylindrical mandrel to form the first resin layer endlessly. An inner layer of the base layer is formed by spirally winding a relatively narrower belt shaped mesh with warp threads running in the major direction of the belt and weft threads running perpendicular thereto, with the weft threads against the outer surface of the first resin layer, and without overlapping the end edges of the belt-shaped mesh. An outer layer of the base layer is formed by inserting the mandrel, with the first resin layer and the belt-shaped mesh layer applied, into a tubular mesh, and pulling the ends of the tubular mesh apart, so as to reduce its diameter and press it radially against the belt-shaped mesh layer. A second resin layer is then applied over the base layer and impregnates the base layer down to the outer surface of the first resin layer, so that the base layer is included within the second resin layer when the second resin layer is cured.

    摘要: A fastening member 30 of a battery terminal 10 has a core wire covering member 32 formed by bending a pair of protecting members 32a which extend from the root portion of a wire barrel 31. The core wire covering member 32 is between the connecting portion 20 and the usual wire barrel portion 31, and is approximately rectangular when seen in cross-section. A clamp bolt 50 and nut 51 are tightened by means of a spanner or the like, thereby attaching the battery terminal 10 to a battery post P. The covering member 32 ensures that the end of the core wire or loose strands of the core wire do not interfere with the tightening operation or become caught on the operator's hand or on a tool. The wire covering members 33, 34 may include inspection apertures 33c, 34b.

    摘要: A female connector housing 11 has a locking arm 30 integrally moulded thereon, the locking arm 30 having a fitting projection 31. A male connector housing 21 has a fitting hole 24 formed on hood member 22 thereof. Two slots 34 are formed on either side of the fitting projection 31 so as to extend along the longitudinal direction of the locking arm 30. The locking arm 30 is thus partitioned into a fitting arm member 35 which includes the fitting projection 31, and two supporting arm members 36 which are formed on both sides thereof. The foot members 36a of the supporting arm members 36 are thicker than the foot member 35a of the fitting arm member 35, and thus the engagement load of the arm 30 is large, but the projection 35a is nevertheless relatively easy to disengage.
