Title: Egr device
Inventor: TAKAYAMA EIJI
IPC: F02M25/07
Filed: 2003-03-12
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problems of starting time becoming long by the deterioration in the air-fuel ratio during cranking, and generating a large quantity of smoke in starting in a technology for forcibly opening an EGR valve before starting opening control of the EGR valve after turning on an ignition switch.  <P>SOLUTION: When a state of being a prescribed value or more in a target lift continues for a prescribed time or more when a difference between the target lift and an actual lift is a specific value or more even if an ECU 6 imparts indication of valve opening to the EGR valve 5 in engine operation after completing starting of an engine 1, the ECU 6 detects a fixation of valve closing. Then, the ECU 6 forcibly opens the EGR valve 5 by imparting indication of full opening to the EGR valve 5 by temporarily stopping ordinary opening control. Forced valve opening is stopped when the actual lift reaches a prescribed lift after releasing the fixation of the valve closing, and is returned to the ordinary opening control. Thus, since the EGR valve 5 is forcibly opened when recognizing the fixation of valve closing in the engine operation after completing the starting the engine 1, the deterioration in the air-fuel ratio during the cranking can be avoided.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

IPC: A61B8/00
Filed: 2003-03-27
Abstract: <P>PROBLEM TO BE SOLVED: To diagnose in a living body by utilizing an ultrasonic wave without loading a patient.  <P>SOLUTION: A motor 26 rotatably drives a first rotation transfer part 28 to give a rotary force to a ring-shaped rotating part 16 through a second rotation transfer part 30.

When the motor 26 rotatably drives the first rotation transfer part 28 to rotate the second rotation transfer part 30, since the second rotation transfer part 30 is screw-clamped with a first columnar member 32, the second rotation transfer part 30 vertically moves. Thus, the axial position of an ultrasonic probe 20 and a position in a surface perpendicular to the ultrasonic probe 20 are controlled by controlling the rotation and the vertical movement of the rotating part 16.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
