Title: Handrail drive device for passenger conveyor
Inventor: KAWASAKI ATSUSHI
IPC: B66B23/04
Filed: 1999-11-11
Abstract: PROBLEM TO BE SOLVED: To provide a handrail drive device of a passenger conveyor restricting, to a specified limit, a pressing force produced on a pressing wheel of a pressing mechanism driving a handrail. SOLUTION: A transmitting rotating body 18 is engaged with a driving rotating body 17 through a torque transmission limiting mechanism. By this, when an unexpectedly large moving resistance occurs on a handrail 3, the upper limit of a torque transmitted from the driving rotating body 17 to the transmitting rotating body 18 is restricted by the function of the torque transmission limiting mechanism and the locking of the transmitting rotating body 18 to the driving rotating body 17 is eliminated.  Thus, the surface of the handrail 3 is not pressed by a pressing wheel 10 with an excessively large pressing force when a large movement resistance occurs on the handrail 3, and such defects that the attractiveness of the handrail is impaired by dents produced on the surface of the handrail by the pressing wheel 10 or that a damage such as deformation occurs on the member of a pressing mechanism 7 can be prevented.

Title: Gate drive circuit and method for generating gate driving voltage
Inventor: RICHIYAADO KEI UIRIAMUZU
IPC: H01L29/78
Filed: 1994-11-30
Abstract: PURPOSE: To make it possible to provide a current in both directions, by providing a first and second regions for limiting a gate driving voltage to a maximum voltage that is determined by the thickness of a gate oxide film, and a voltage generating circuit connected to the gate. CONSTITUTION: A gate oxide film cannot withstood a voltage of 10V or above, because an inversion phase for shielding the gate oxide film from the potential of a substrate is produced. Accordingly, when one region (drain) 1304 is normally held at a high positive potential during the continuity state of current, the gate driving circuit can adopt the other lower potential region as a reference. The combination of such a gate driving circuit and a MOSFET produces a MOSFET which holds only the current from the gate 1302 of the MOSFET to the source region 1304. In this case, the current flowing in the MOSFET can be made to flow from the region 1302 to the region 1304 or from the region 1304 to the region 1302.
