    摘要： A multiplex transmission system (100) in which any (N.sub.i) of a plurality of nodes (N.sub.1 -N.sub.n) connected loop-like with a bidirectional signal transmission path (1a, 1b) and each respectively connected to control one of a plurality of units of electrical equipment is adapted for transmitting, in a given order (i), a prepared signal (A.sub.i, D) to the signal transmission path (1a, 1b) and for receiving a prepared signal (A.sub.i, D; A.sub.x, D) from the signal transmission path (1a, 1b), wherein any (N.sub.i) of the nodes (N.sub.1 -N.sub.n) has a rise-timing timer (CNT.sub.2), on which a rise-timing time interval (t.sub.i3, t.sub.i4) of a length proper to this node (N.sub.i) is set at a predetermined time point (54, 62, 71, 84, 88), and is adapted for rising to start signal transmission when the rise-timing timer (CNT.sub.2) has timed out.The signal transmission path (1a, 1b) includes a pair of signal transmission lines (1a, 1b), and any (N.sub.i) of the nodes (N.sub.1 -N.sub.n) is adapted, when this node (N.sub.i) is at the order of signal transmission of its own, for transmitting the prepared signal (A.sub.i, D) to the signal transmission lines (1a, 1b) and receiving the prepared signal (A.sub.i, D; A.sub.x, D) from one (1a) of the signal transmission lines (1a, 1b) and for checking the signal (A.sub.i ', D') as thus received with the signal (A.sub.i, D) as transmitted, to thereby diagnose for abnormality of the aforesaid one (1a) of the signal transmission lines (1a, 1b).

    摘要： A catalytic exhaust cleaning device for a high-power multi-cylinder engine of the type including independent carburetors and exhaust pipes for the respective cylinders. The exhaust pipes are interconnected for fluid communication therebetween at locations upstream of the respective catalytic converters arranged therein so that the latter are evenly fed with exhaust gases of substantially the same composition and volume and with substantially equal amounts of secondary air and operate effectively with substantially the same high efficiency. The exhaust communicating pipe interconnecting two adjacent exhaust pipes is divided into two sections, which are fixed at one end to the respective exhaust pipes and held at the other end in aligned abutting relation by a radially expansible tubular joint member, which is fixed to one of the two pipe sections and clamped against the other section. This structure not only facilitates assembly of the communicating and exhaust pipes but effectively prevents any thermal deformation of the communicating pipe.
