Patent number: 6420693Abstract: In the foreign object insertion detector device, the light (infrared rays) is transmitted into the internal space 13 of a tube body 11 implanted into a weather strip 9 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 11 to thereby deform the tube body 11. If the tube body 11 is deformed in this manner, then the quantity of the light transmitted through the internal space 13 is caused to decrease. By judging whether a decrease in the quantity of the light transmitted through the internal space 13 is present or absent, the insertion of the foreign object can be detected.Type: GrantFiled: September 7, 1999Date of Patent: July 16, 2002Assignees: Autonetworks Technologies, Ltd., Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd.Inventors: Naohiro Nakatsuji, Masahiro Kume, Morihiko Toyozumi, Yasuyo Matsumoto, Mitsutoshi Kamakura

Patent number: 5537013Abstract: 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.Type: GrantFiled: March 14, 1995Date of Patent: July 16, 1996Assignee: Sumitomo Wiring Systems, Ltd.Inventors: Morihiko Toyozumi, Naohiro Nakatsuji

Patent number: 5410227Abstract: This invention aims to prevent an obstacle from being trapped between a vehicle window and a window frame. A supersonic wave f is emitted into a vehicle window W. A reflection wave i of the supersonic wave is received to decide whether the reflection wave i is one reflected from peripheral faces of a target to be detected or not. If the received reflection wave i is one reflected from the peripheral faces from the target, a driving motor M for the vehicle window W is stopped. Thus, when an obstacle contacts with the peripheral faces of the vehicle window, it is possible to previously prevent the obstacle from being caught by the window since a driving source for the vehicle window is stopped.Type: GrantFiled: July 28, 1993Date of Patent: April 25, 1995Assignees: Sumitomo Wiring Systems, Ltd., Sumitomo Electric Industries, Ltd.Inventors: Morihiko Toyozumi, Shinichiro Takahashi
