Title: Method of sewing at least two sheets of fabric material part together and sewing machine for implementing the same
Inventor: HOSAGASI SEVKI
IPC: D05B47/04
Filed: 2002-03-05
Abstract: PROBLEM TO BE SOLVED: To generate seams highly valuable in quality even for a slightly larger range of the number of revolutions derived from the conception that the tension of threads necessary for the generation of the seams highly valuable in quality varies with the number of revolutions because it is not consistent with the number of revolutions. SOLUTION: In a sewing machine (1), a thread tightening device (29) is provided having a thread tightening tool (32) driven by an electromagnet (34). Currents of the electromagnet (34) flowing through a bobbin (33) are altered according to a standardization elapse curve attributively calculated in terms of the number of revolutions of the sewing machine (1). Eventually, this keeps the intersection of needle threads (23) with bobbin threads between the fabric material parts to be sewn together even in the sewing under different numbers of revolutions.

IPC: F02D9/02
Filed: 2002-03-27
Abstract: <P>PROBLEM TO BE SOLVED: To decide abnormality in opening and closing operation of an EGR valve and an intake throttle valve using a pressure sensor in an internal combustion engine.  <P>SOLUTION: In the internal combustion engine 1, NOx is reduced by supplying a reducing agent to a particulate filter 12 carrying a storage reduction type NOx catalyst. In this method for determining abnormality in the internal combustion engine, the abnormality in opening and closing operation of the EGR valve 15 or the intake throttle valve 7 is determined by a change in pressure of upstream of the particulate filter 12 at the time of reducing NOx. When the EGR valve 15 or the intake throttle valve 7 is opened or closed, a flow rate of an exhaust gas is changed and the pressure of the upstream of the filter is changed. Since the opening and closing operation of the EGR valve 15 or the intake throttle valve 7 correlates with the pressure of the upstream of the filter 12, it is possible to decide the abnormality in opening and closing operation of the EGR valve 15 or the intake throttle valve 7 based on the pressure of the upstream of the filter 12.  <P>COPYRIGHT: (C)2004,JPO
