Title: Elastic tube for expanding diameter
Inventor: IKUNO SHIGEO
IPC: H02G3/04
Filed: 2004-02-13
Abstract: <P>PROBLEM TO BE SOLVED: To provide an elastic tube for expanding a diameter without a possibility of growing to an entire crack even if a very small crack occurs at the tip part of a narrow diameter part.  <P>SOLUTION: The elastic tube for expanding the diameter of this invention is an elastic tube for expanding the diameter whose diameter is expanded to be attached to both end parts of an insulating tube protecting a connection part of an electric cable. Since a stress relaxation area 2 widened toward the tip side in a circular arc shape is provided at the tip part of the narrow diameter part 1 of the elastic tube A formed in a shape of a Sake bottle so that the inner diameter D of the tip part is large, a diameter expanding rate at the tip end of the narrow diameter part becomes small and the stress applied to this part is relieved. Thus, the small crack at the tip part can be prevented from growing to the entire crack.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Title: Mass spectroscope
Inventor: BABA TAKASHI
IPC: H01J49/40
Filed: 2004-02-17
Abstract: <P>PROBLEM TO BE SOLVED: To provide a mass spectrometric analysis technology realizing a high-efficiency and high-speed ECD without use of an FT-ICR.  <P>SOLUTION: Combined ion trap parts 2 to 11 equipped with an electron source 12 and with a magnetic field impressed nearly parallel along a center axis are used. First, a parent ion is trapped. With an adoption of combined ion trapping, a high ion capturing performance is obtained at incidence and trapping. In sequence, electron is wound around and emitted by a magnetic field along the center axis without high frequency applied. Thus, the energy-controlled electron can be made to reach the parent ion trapped. Avoiding heating due to a high-frequency field, a mass spectroscope using a high-speed and high-efficiency ECD is realized without the use of the FT-ICR.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To suppress initial unevenness of a fuel injection device with a boosting device and unevenness of amount of fuel supply to each cylinder due to change of characteristic while an engine is operated.  <P>SOLUTION: A boosting unit 110 is provided on each fuel injection valve of the engine 1 and fuel pressure supplied to the fuel injection valve from a common rail 3 is boosted as required. An ECU 20 performs low pressure injection while the boosting unit is not operated and performs high pressure injection while the boosting unit is operated and fuel supply pressure to the fuel injection valve rises up to boost pressure to correct a fuel injection period of the fuel injection valve based on the result. Upon completion of correction of fuel injection period, fuel injection is performed after operation of the boosting unit starts and before fuel supply pressure reaches the boost pressure to adjust operation timing of the boosting unit based on the result. Consequently, both of the fuel injection valve and the boosting unit can be properly compensated while the engine is operated.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
