Abstract:
A bicycle derailleur comprises a base member adapted to be mounted to a bicycle, a movable member movably coupled to the base member, and a chain guide coupled to the movable member. The chain guide is coupled for rotation around a rotational axis (X), and a biasing element biases the chain guide in a selected rotational direction. A resistance applying unit applies a resistance to rotational movement of the chain guide in a direction opposite the selected rotational direction, and an adjusting unit adjusts an amount of resistance applied by the resistance applying unit.
Abstract:
A conductor for use in a flat cable includes thereon a tin or tin alloy plating the thickness of which is substantially uniform over the whole periphery of a flat conductor, in order to provide a conductor for use in a flat cable which can minimize variations in the plating thickness thereof, provide a good contact reliability with respect to a connector when it is used in a flat cable, and causes no increase in the contact resistance thereof in a humidity withstand test after it is inserted into and removed from the connector.
Abstract:
A barrier mechanism includes a barrier blade group (G1) having barrier blades (A1), (B1), (C1) which are rotatably retained by a single spindle (S11); an elastic member (E11) provided to the spindle (S11) substantially coaxially with a rotating center of the barrier blade group (G1), and configured to generate torque for driving the barrier blade (A1) to rotate,' and a frame member formed by a barrier cover (F1) and a barrier (F2) each including an aperture serving as a window for opening an effective optical path of an optical lens, and configured to house the barrier blade group (G1) and the elastic member (E1) between these members. The spindle (S11) includes a flange portion (S11f) configured to separate the barrier blade group (G1) from the elastic member (E11) in a direction of an optical axis.
Abstract:
A bicycle component positioning device includes a fixed member, an operating member and a positioning mechanism. The operating member has an input portion and an output portion. The positioning mechanism is operatively disposed between the operating member and the fixed member. The positioning mechanism includes a positioning member that is movable between a first position in which the positioning member is engaged with the fixed member and a second position in which the positioning member is disengaged from the fixed member. The positioning member is held in engagement with the fixed member in the first position by the input portion when the input portion is in an operating position. The positioning member is movable from the first position to the second position upon movement of the input portion from at least one of the operating positions.
Abstract:
A dephosphorization material is formed from concrete sludge resulting from centrifugal casting of concrete products, production of concrete, cleaning of concrete production equipment, or cleaning of concrete transporting vehicles. The dephosphorization material is used for dephosphorization treatment by a dephosphorization apparatus that includes a single reaction tank provided with a wastewater supply means, a dephosphorization material supply mean, and a recovery means. The dephosphorization apparatus removes phosphorus from phosphorus-containing wastewater, such as sewage water, based on the formula 10Ca2++6PO43−+2OH−→Ca10(PO4)6(OH)2 and recovers through the recovery means a dephosphorization by-product that precipitates as crystals as a result of the reaction.
