Title: Elevator operating system
Inventor: HANDA MANABU
IPC: B66B1/06
Filed: 2000-02-21
Abstract: PROBLEM TO BE SOLVED: To provide an elevator operating system detecting the disconnection of the wire for an elevator non-stop switch or an elevator stopping switch for holding the elevator non-stopping function and the elevator stopping function effective and giving an alarm outside. SOLUTION: When the wire or the elevator non-stopping switch is disconnected, relays 3 and 4 are turned off and a relay 5 is turned on. The turning on of the relay 5 closes a contact 5a for turning relays 4a and 6 on. When the relay 4 is turned on, the elevator non-stopping function and the elevator stopping function are held effective, and the turning of the relay 6 on gives an alarm. As a result, since even if the wire for the elevator non-stopping switch or the elevator stopping switch is disconnected, the non-stopping function and the stopping function are left effective, and an alarm is also given, the elevator never serves to the floor to which access is prohibited for preventing offenses such as larcenous from happening.

IPC: B01D53/94
Filed: 2000-02-24
Abstract: PROBLEM TO BE SOLVED: To reduce exhaust quantity of HC(hydrocarbon) reserved in a suction air passage while an engine stops to the atmospheric air. SOLUTION: An HC adsorbent 18 is provided in a surge tank 15, and an opening and closing valve 20 to change a contact degree of intake air and the HC adsorbent 18 is provided on the upstream side of this HC adsorbent 18. Residual HC in a suction air passage is adsorbed by the HC adsorbent 18 while the engine stops, and HC is release from the HC adsorbent 18 by increasing the contact degree of the intake air and the HC adsorbent 18 by opening the opening and closing valve 20 after a catalyst 22 comes to be in an active state after starting. Consequently, it is possible to purify HC by the catalyst 22 in the active state even when HC released from the HC adsorbent 18 is not sufficiently burnt in a cylinder and discharged to an exhaust pipe 21.  Additionally, HC release reduces and corrects fuel injection quantity in accordance with release quantity of HC from the HC adsorbent 18 and prevents slippage of an air-fuel ratio of exhaust gas from a target air-fuel ratio (purifying window of the catalyst 22).
