Patent number: 6046510Abstract: A control system is provided for controlling electric devices installed in a slide door which moves relative to a door opening formed in a vehicle body. The control system comprises a first electric device for detecting a door-closed condition wherein the slide door is at its fully closed position relative to the door opening and a second electric device for positively suppressing operation of the electric devices until the time when the first electric device detects the door-closed condition. For achieving communication between the first and second electric devices, an electromagnetic induction phenomenon is practically used.Type: GrantFiled: March 20, 1998Date of Patent: April 4, 2000Assignee: Ohi Seisakusho Co., Ltd.Inventors: Osamu Kawanobe, Tomoaki Monzen

Patent number: 6037727Abstract: A vehicular slide door open-close control apparatus for opening a slide door installed at a side of vehicle body by means of the drive source such as a motor and the like. The purpose of the apparatus is to reduce a burden applied to the slide door moving from its full-open position along its close direction, downsize, lighten and lower the cost. Also, reducing an operational force when the door is manually closed. The control apparatus has a drive source 54 such as motor and the like, a slide door 3 open-close-moved by a slide door open-close mechanism, a clutch means 56 transmitting intermittently a drive force of the drive source 54 to the slide door open-close mechanism, a slope judgement means 76 detecting a vehicle posture and a slide door control means 7 controlling the drive source and clutch means in order to adjust a drive force to be transferred to the slide door open-close mechanism.Type: GrantFiled: August 14, 1997Date of Patent: March 14, 2000Assignee: OHI Seisakusho Co., Ltd.Inventors: Osamu Kawanobe, Ryoji Shimura

Patent number: 5726881Abstract: A centrifugal apparatus includes a rotor having a marker for generating an index signal, a motor for rotating the rotor, first and second detectors for detecting the index signal with rotation of the rotor to generate first and second detection signals, an input terminal for receiving supply power, a drive circuit for generating a drive signal from the supply power according to the first detection signal, and first and second switch circuits for controlling the supply of the drive signal to the motor. First and second judging portions are used to detect whether the first and second detection signals are respectfully generated within a given condition.Type: GrantFiled: August 14, 1995Date of Patent: March 10, 1998Assignee: Hitachi Koki Co,. Ltd.Inventors: Masahiro Inaniwa, Shinji Watanabe, Nobuharu Kido, Noriyasu Matsufuji, Yoshitaka Niinai, Osamu Kawanobe

Patent number: 5689160Abstract: A drive control device for an opening/closing member may be advantageously utilized in vehicular power window systems and the like. The drive control device is active to detect occurrence of pinching of an object obstructing the path of motion of the opening/closing member and, upon detection of such pinching during closing operation is controlled so as to move in the opening direction for a predetermined distance for preventing serious pinching from being applied to, for example, a persons hand or arm which may be blocking a power window while being closed by a vehicle driver. The drive control device further includes timing functions such that closing operation may not be immediately resumed after pinch detection, until a predetermined time period has elapsed. The pinch detection operation is effective to compensate for overrun of the opening/closing member caused by a lag between the time a closing control signal is stopped and the acutal motion of the opening/closing member finally and completely stops.Type: GrantFiled: February 28, 1995Date of Patent: November 18, 1997Assignee: Ohi Seisakusho Co., Ltd.Inventors: Kouichi Shigematsu, Osamu Kawanobe

Patent number: 5640807Abstract: A powered vehicle door closing system for producing an auto-closing action to automatically move a latch member from a half-latched position to a fully-latched position comprises a reversible motor mechanically linked through a linkage to the latch member, for powering a final, low-displacement/high-force movement of a vehicle door, and a controller for controlling the motor. The controller includes a full-latch confirmation section for confirming that the latch member is maintained at its fully-latched position, and a motor-drive limiting section for limiting re-activation of the motor so as to avoid ineffective auto-closing action of the system when the full-latch confirmation section decides that the latch member has already been shifted to and maintained at the fully-latched position.Type: GrantFiled: December 11, 1995Date of Patent: June 24, 1997Assignee: Ohi Seisakusho Co., Ltd.Inventors: Kouichi Shigematsu, Osamu Kawanobe, Jun Yamagishi

Patent number: 5632120Abstract: A powered vehicle door closing system for producing an auto-closing action to automatically move a latch member from a half-latched position to a fully-latched position, comprises a reversible motor mechanically linked through a linkage to the latch member for powering a final, low-displacement/high-force movement of a vehicle door, a half-latch detection switch such as a limit switch, and a controller for controlling the motor. The controller comprises a full-latch detection section for detecting the fully-latched position of the latch member and a stand-by position detection section for detecting the stand-by position of the linkage. To detect the fully-latched position and the stand-by position, the full-latch detection section and the stand-by position detection section respectively utilize changes in load imparted to the motor.Type: GrantFiled: December 11, 1995Date of Patent: May 27, 1997Assignee: Ohi Seisakusho Co., Ltd.Inventors: Kouichi Shigematsu, Osamu Kawanobe, Jun Yamagishi

Patent number: 5530329Abstract: A drive control device for an opening and closing member is active to optimally adjust a threshold level for pinch detection. Utilizing a speed sensor or the like, the closing speed of the opening/closing member is detected. The value of the closing speed is renewed in accordance with the closing position and stored in memory. Based on memorized data, a predicting circuit derives a future closing speed. To the predicted value there is added an allowed addition value, to permit a threshold level setting circuit to set an appropriate threshold for pinch detection. The allowed addition value is adjusted in accordance with the closing speed of the opening/closing member by a threshold level adjusting circuit.Type: GrantFiled: March 28, 1995Date of Patent: June 25, 1996Assignee: Ohi Seisakusho Co., Ltd.Inventors: Kouichi Shigematsu, Osamu Kawanobe
