摘要:
A gas reaction apparatus has an activation chamber, a heat exchanger and a reaction chamber. A gas is introduced into the activation chamber and activated there by electric discharge. The activated gas is then cooled by the heat exchanger in case a reaction to be effected in the reaction chamber is exothermic or heated by the exchanger in case a reaction to be effected in the reaction chamber is endothermic. The heat resulting from the reaction with the gas can therefore be effectively removed so that a desired reaction is rapidly conducted in the reaction chamber without being followed by a side reaction.

A bush bearing includes a synthetic resin-made bush having a circumferential groove on its outer peripheral surface; an endless annular elastic member fitted in the circumferential groove of the bush; and a positioning structure for determining the position of the bush in a B direction with respect to an inner peripheral surface of a gear housing.

A steering apparatus includes an attaching bracket connecting end portions of a pair of tie rods to a rack shaft. The attaching bracket includes a base which is fixed to the rack shaft and includes at least one fixing member inserting hole through which a fixing member fixing the attaching bracket to the rack shaft is provided, and a supporting stay supporting the end portions of the pair of tie rods via ball joints respectively. The supporting stay extends from an intermediate portion of the base in an axial direction of the rack shaft. A center of the ball joint supporting the end portion of each of the tie rods is positioned offset from an axial line of the fixing member by a predetermined distance when viewed along the axial direction of the rack shaft.

A rack and pinion steering device has a pinion rotatable in the R-direction, a rack bar having rack teeth meshing with the pinion and rectilinearly movable in the A-direction, a housing for rotatably supporting the pinion, a rack guide for slidably supporting the rack bar, and an elastic means for pressing the rack guide toward the pinion.

A center-takeoff rack-and-pinion steering apparatus includes a connecting unit arranged to connect respective ends of a pair of tie rods for steering a pair of vehicle wheels to an axially intermediate portion of a rack shaft. The connecting unit includes a slider slidably movable on an inner periphery of an elongate hole of a rack housing. A sliding contact surface on the inner periphery of the elongate hole and a sliding contact surface of the slider, which slide on each other, are inclined in both a widthwise direction of the elongate hole which is perpendicular to a longitudinal direction of the elongate hole and a depthwise direction of the elongate hole.

A rack guide includes a rack guide base body which has on its outer peripheral surface a pair of semicylindrical surfaces and a pair of planar surfaces each located between the pair of semicylindrical surfaces, has a concavely recessed surface located on one axial end portion side inwardly of the pair of semicylindrical surfaces and the planar surfaces, and has a cylindrical surface located on the other axial end portion side inwardly of the pair of semicylindrical surfaces and the planar surfaces; and a slider secured to the rack guide base body.
摘要:
In the treatment, a reverse osmosis membrane element having a polyamide skin layer is loaded in a pressure vessel in a membrane separator and contacted with a bromide-containing aqueous solution of free chlorine. The thus treated reverse osmosis membrane element retains for a long time its effect of reducing solute concentration in a solution treated with the reverse osmosis membrane and rejects efficiently non-electrolytic organic materials or substances such as boron that will not be dissociated in a neutral region. A reverse osmosis membrane module having the thus treated reverse osmosis membrane element is provided as well.
摘要:
A polyamide skin layer is formed on a porous support by reacting an aromatic compound having at least two reactive amino groups with a polyfunctional acid halide compound having at least two reactive acid halide groups. Then, the polyamide skin layer is treated with a free chlorine aqueous solution containing bromine compound. The resultant composite reverse osmosis membrane has a high rejection for substances that are not ionized at the pH range where the membrane is normally used.
