Abstract: A seat device equips a walk-in mechanism and a fold down mechanism (a seatback is turned down with large angle so as to attain the flat condition). These mechanisms can be operated selectively using a simple operation without using plural levers. A base bracket of the seat device is fixed to a lower arm. The base bracket has a stopper and pivotally supports the first link member and the second member in a freely turning way. An upper arm has a contact portion. If the upper arm is turned down in the forward direction for the walk-in operation, the contact portion gets in contact with an intervening member of the first link member so as not to turn further down in the forward direction. In the case that the seatback is turned to the flat condition, the intervening member is moved towards the outside portion of the locus of movement of the contact portion. Consequently, the contact portion of the upper arm can be turned down on a large scale without getting in contact with the intervening member.

Abstract: A seat device is provided, in which a locking condition of an upper rail (2) to a lower rail (1) is released and a seat can be moved in forward direction when a seatback is turned down in forward direction due to a walk in operation. A turning bracket (18) is pivotally supported on the side portion of a lower arm (3) fixed to the upper rail (2). An actuating lever (20) for actuating a lock mechanism is fixed to a turning pin (17) for supporting a turning bracket (18). A cable (15) is connected to the turning bracket (18), a hook member (22) is pivotally supported on the side portion of the lower arm (3), and a detecting member (29) is supported thereby in a turning way. A projecting portion (25) of a hook member (22) can be engaged with or disengaged from a notch portion (31) of a turning bracket (18).

Abstract: A seat slide device for a vehicle includes a lower rail, an upper rail and a shoe. The shoe includes a base portion attached to an engaging portion of one of the rails and a slide portion slidable along an engaged portion of the other rail. The slide portion and the base portion are integrally formed with one another. The slide portion contacts the base portion when a load equal to or greater than a predetermined load is applied, and the base portion has a surface possessing a shape which increases the contact area with the slide portion when the load increases.

Abstract: Angle sensor including a permanent magnet and a Hall effect element and which provides accurate detection of a rotational angle of an object on which it is mounted. The magnet is mounted on a rotor at a distance below the rotational center of the rotor when the rotor is in its reference position and such that the rotational center is situated on an axis that connects the poles of the magnet. An electronics package including the Hall element is fixed to a portion of the housing of the sensor such that the Hall element is at a distance from the rotational center and is positioned on the axis of the permanent magnet. The electronic package is oriented so that the magnetic flux detection direction of the Hall element is perpendicular to the axis of the permanent magnet. By slightly shifting the position of the Hall element from the rotational center of the rotor, the angle sensor provides highly accurate detection of the rotational angle of the object on which it is mounted.

Abstract: A seat device for a vehicle includes a seat apparatus rotationally mounted on the floor of the vehicle to permit the seat apparatus to move between a first position in which the seat apparatus is adjacent the floor of the vehicle and a turned over position in which the seat apparatus is upright relative to the floor of the vehicle. The seat apparatus includes a seat back and a seat cushion, with the seat back being pivotally mounted with respect to the seat cushion to permit the seat back to be pivoted between a sitting position and a forwardly folded position on top of the seat cushion. A lock device locks the seat apparatus to the floor of the vehicle and prevents the seat from being moved to the turned over position. A mechanism is also provided for releasing the lock device to permit the seat apparatus to be moved to the turned over position only when the seat back is in the forwardly folded position.

Abstract: The invention concerns a gas diffuser constructed and arranged to disperse gas into a aeration vessel of a water treatment assembly from a blower. The gas diffuser includes main pipes, branch pipes extending between the main pipes and containing gas discharge ports, wherein the branch pipes have a smaller cross-sectional area than the cross-sectional area of the main pipes. The gas discharge ports are further sized, constructed and arranged to reduce the possibility or likelihood of sludge from blocking the ports or entering the branch pipes. This object is achieved either by placement of the ports on the bottom sides of the branch pipes or, alternatively, by construction of the ports to include conduit members, themselves having an arrangement of openings or coverings to prevent or reduce the likelihood of sludge from blocking the ports or entering the branch pipes.

Abstract: A method for cleaning separating membranes uses a uniquely formulated detergent. The detergent includes a percarbonate-containing, material, existing in the condition in which hydrogen peroxide is adducted in carbonate and is desirably an alkali metal salt. The percarbonate decomposes the organisms deposited on the membrane surfaces while being environmentally desirable. The detergent preferably also includes at least one bivalent iron salt, which improves the cleaning capability of the percarbonate via the so-called Fenton's reaction in which hydrogen peroxide adducted in the percarbonate reacts with the iron ions to form OH— radicals which have a very high oxidative reactivity. The detergent may also contain other oxidizers, a surfactant, a chelating agent, an acid and a pH regulator. The detergent is dissolved in water prior to use.

Abstract: A membrane separator assembly for separating solids from water includes opposing enclosure wall structures, a membrane module unit, and a gas diffuser disposed below the membrane module unit. The membrane module unit includes a plurality of membrane modules respectively having at least one separating membrane extending between at least two membrane fixing members. At least one of the membrane fixing members has a main passage which is in fluid communication with a membrane passageway. The membrane passageway is accessible to water via permeation through the separating membranes and is inaccessible to solids which are impermeable relative to the separating membranes. The membrane separator assembly is preferably used with a detergent containing percarbonate, preferably sodium percarbonate. The assembly also includes a gas diffuser with two opposing main pipes and branch pipes extending therebetween to avoid undesired pressure differentials when cleaning the assembly.
