In the foreign object insertion detector device, the light (infrared rays) is transmitted into the internal space of a tube body implanted into a weather strip and formed of elastic material and, if there occurs the insertion of a foreign object, then the foreign object produces a pressing force and applies the pressing force to the tube body to thereby deform the tube body If the tube body is deformed in this manner, then the quantity of the light transmitted through the internal space is caused to decrease. By judging whether a decrease in the quantity of the light transmitted through the internal space is present or absent, the insertion of the foreign object can be detected. In order to able to detect the pressing force given from obliquely downward directions C and D by the foreign object with high sensitivity, in the obliquely downward car exterior side or obliquely downward car exterior side of the tube body in the weather strip as pressing means there are formed cavity portions as well as projecting portions 37, 39. Thanks to this structure, the pressing force from the foreign object can be applied through the projecting portions and to the tube body collectively without being dispersed.

In a multiplex communication system, as to all of the vehicles, the arbitrarily-mounted apparatuses can be connected to the transmission path, and also only the arbitrarily-mounted apparatus having the specific output circuit is separately and selectively can be connected to the transmission path, depending upon such a specific attribute condition when the individual vehicle is supplied, and this specific output circuit is suitable for this specific attribute condition. Accordingly, as the arbitrarily-mounted apparatus suitable for the respective attribute conditions, all of the output functions, all of the output functions which are not required for these attribute conditions can be excluded, and the useless output circuits can be omitted, resulting in a cost reduction. Thus, it is possible to realize the space-saving on-vehicle multiplex communication system. At the same time, only the minimum number of arbitrarily-mounted apparatus is merely added so as to change the other vehicle sorts and the other vehicle destination regions.

On-vehicle multiplex communication system and manufacturing method thereof

A system is provided to automatically terminate a fail-safe state. When an abnormality detection signal of Lo and a pulse having a frequency outside a specified range are input to set and reset terminals S, R of an R-S Flip-Flop (R-SFF) 24, respectively, a microcomputer 14 is determined to be in its abnormal state and an output of Hi is output from a Q output terminal of the R-SFF 24 to stop the operation of a motor 20. In this way, a so-called fail-safe state is established. When the abnormality detection signal of Hi and the pulse having a frequency within the specified range are input to the set and reset terminals S, R of the R-SFF 24, respectively, the microcomputer 14 is determined to have returned to its normal state and an output of Lo is output from the Q output terminal of the R-SFF 24 to resume the operation of the motor 20. Thus, the operation of the motor 20 can be controlled according to the operation of a power window switch 16.

Fail-safe system and method of operation

This invention prevents a power window from trapping a hand or the like during manual opening and closing of the window as well as during automatic opening and closing of the window. A current-flowing unit 56 flows a current in a closing direction in a power window motor 58 by turning on a sub-switch 57 for a passenger's seat window. While a catching detector 61 generates a detecting signal when an obstacle is present, a breaker 63 breaks a current flowing in a closing direction in the motor 58 through the unit 56 by turning off a master switch 39 for the passenger's seat. A reversing unit 65 rotates the motor 58 in a reverse direction by flowing a current in an opening direction in the motor 58. Even if an obstacle is present during an operation of closing the manual sub-switch 57, it is possible to release window, thereby freeing the obstacle.
