The present invention can include a vehicle seat having a table, the table including a table main body, a shaft member, a first hinge structure that pivotably connects the table main body to one face of the vehicle seat and a second hinge structure that pivotably connects the shaft member to the one face of the vehicle seat. The table main body includes a holding member which is capable of slidably holding a front end portion of the shaft member and a lock member which is capable of engaging with the shaft member, and the lock member is provided at a position different from the holding member. Further, the table main body is movable between a containing position constituting a state of facing the one face of the vehicle seat and a using position constituting substantially a horizontal state by movement of the shaft member, and the lock member is engaged with a front end side portion of the shaft member at the using position and engaged with a back end side portion of the shaft member at the containing position.

A point-to-multipoint communication system is presented to enable a reliable, high quality communication using multiplexed optical signals between a central office equipment and a plurality of subscriber's equipment. The system is provided with a plurality of office transceivers in the central office equipment, and the each of the subscribers is provided with at least one subscriber transceiver. The system is designed so that a redundancy system is built-in by providing one of either the office transceivers, a plurality of subscriber's transceivers or the optical connection device, to connect the two sets of transceivers at all times. One of these redundancy systems provides an operating connection between each of the office transmitters which are connected to the office transceivers and each of the subscriber transmitters which are connected to the subscriber transceivers. Therefore, when a malfunction occurs somewhere in the optical network, the least number of the malfunctioning components need to be switched over the the normally functioning system to maintain continued communication services. The present communication system is designed with the least number of active components, therefore, the failure probability is significantly decreased, and repairs if necessary can be preformed quickly. The overall effect of the present system is that interactive point-to-multipoint communication services of high quality and reliability are provided at reasonable cost.

A self-excited inverter circuit primarily includes a main transformer two switching elements e.g. the first and second (FET) switching elements, wherein capacitors at both ends of said first FET are charged during a time T.sub.1 -T.sub.2 when said first FET is turned off, and the voltage V.sub.g1 across said first FET is clamped by a charge voltage V.sub.c1 and then, a voltage V.sub.gs is applied across the gate and the source of said second FET for electrical continuity to cause the voltage to be clamped. The clamped state is maintained from T.sub.1 to T.sub.2, the saturation reactor is saturated at time T.sub.3, and V.sub.gs, which has been negative, starts to change toward O, thereby causing the first FET to change to ON; V.sub.q falls towards VPi at TP3 and further towards zero point. Thus, the voltage V.sub.q2 changes to zero to cause V.sub.gs of the second FET to become zero and the second FET to be shut off. When said voltage V.sub.q2 is clamped to a fixed value, a high -V.sub.sc (L) can be obtained in the case of Vi(L), whereas a low -V.sub.sc can be obtained in the case of Vi(H); and the continuity angle, or duty cycle, (T.sub.1 -T.sub.2)/(T.sub.1 -T.sub.3) of the first FET is naturally controlled to be kept in a desirable direction.
