摘要： A pin secured at one end of a link is inserted into an L-shaped groove of aock lever pivoted to the upper surface of an upper guide rail and the other end of the link is connected to an actuator by way of a wire. The hook of the lock lever can be inserted into the hook hole of the flange of the lower guide rail. Rotating of the lock lever and thus rotation of the upper guide rail relative to the lower guide rail by an accidental external force to the lock lever can be prevented in the rotatable seat.

First and second series circuits are connected in parallel, the first series circuit being formed of first and second diodes and the second series circuit being formed of a third diode connected with the collector-emitter circuit of a transistor. The base electrode of the transistor is connected to the junction defined by the first and second diodes such that the base-emitter circuit thereof is in parallel arrangement with the second diode. A current source is connected to the parallel-connected series circuits so as to supply currents thereto. An input signal is supplied to the junction defined by the first and second diodes; the first and second outputs are coupled to this junction and to the collector electrode of the transistor, respectively, for providing differential output signal currents that are a function of the supplied signal. This circuit can be connected to a differential amplifier to supply differential signals to the latter, whereby a gain controlled amplification of the original single-ended input signal can be attained.
