Title: Document reader
Inventor: NAMIKAWA HIROSHI
IPC: B65H7/12
Filed: 2007-02-26
Abstract: <P>PROBLEM TO BE SOLVED: To provide a document reader capable of precisely detecting documents being fed together one over the other without reference to the conveying speed of the documents.  <P>SOLUTION: An ultrasonic wave is transmitted toward a document conveyance path at constant transmission periods T1 and a receiver provided on the opposite side from the transmitter across the conveyance path receives the ultrasonic wave. The output signal from the receiver is compared with a reference level L and the comparison result is extracted at predetermined sampling periods T2 to periodically detect documents being fed together one over the other. The sampling period T2 is varied based upon the conveying speeds of the documents. Thus, the sampling period T2 is varied based upon the conveying speed of the documents to prevent variance in number of times of multiple feed of documents from being generated as the conveying speed varies. Consequently, the multiple-sheet feeding can equally be detected on documents irrespective of the conveying speed of documents, so that the multiple-sheet feeding can be detected more precisely.  <P>COPYRIGHT: (C)2008,JPO&INPIT

Title: Idling control device for internal combustion engine
Inventor: NISHIYAMA MASATERU
IPC: F02D41/16
Filed: 2007-03-07
Abstract: <P>PROBLEM TO BE SOLVED: To improve fuel economy during idling operation of an engine.  <P>SOLUTION: Since a combustion condition is improved and fluctuation quantity of actual idling speed gets small when opening of TCV (Tumble control Valve) is controlled to a close side and tumble flow in a cylinder is intensified, fluctuation quantity of actual idling rotation speed can be regulated in tolerance even if actual idling speed id lowered by lowering target idling speed. Taking this point into account, TCV opening is compensated to a closure side judging that it is not under idling up control (in normal idling operation) at timing t1 when it is judged that actual idling speed NE is lower than a predetermined value C during idling operation, then target idling speed TNE is compensated to low speed side at timing t2 when it is judged that actual idling speed NE is stable. Consequently, fuel economy is improved by lowering actual idling speed while keeping the fluctuation quantity of actual idling speed within the tolerance.  <P>COPYRIGHT: (C)2008,JPO&INPIT
