Title: Valve timing control device of internal combustion engine
Inventor: KINOMURA SHIGEKI
IPC: F02D41/06
Filed: 2002-01-07
Abstract: <P>PROBLEM TO BE SOLVED: To improve startability of an internal combustion engine even when it is placed in a low startability environment by avoiding unnecessary control of valve timing.  <P>SOLUTION: This valve timing control device of an internal combustion engine is constituted such that the valve timing is locked to a predetermined position advanced to a lag position at the time of stopping the internal combustion engine. This device comprises a startability estimation means (step S1) for estimating whether an environment when the internal combustion engine is restarted after it is stopped is a low startability environment with low startability, and a lock means (step S2) locking the valve timing to the predetermined position when the startability estimation means (step S1) estimates that the environment at the time of restarting becomes a difficult-to-start environment.  <P>COPYRIGHT: (C)2003,JPO

Title: Multistage centrifugal pump
Inventor: KUBOTA KOJI
IPC: F04D29/046
Filed: 2002-01-09
Abstract: <P>PROBLEM TO BE SOLVED: To provide a centrifugal pump delivering easy-to-boil liquefied gas with small amount and high lift.  <P>SOLUTION: A plurality of centrifugal pumps 12 are arranged on a single drive shaft 14 driven by a motor 16, constituting an extremely low specific speed multistage centrifugal pump 10 with a specific speed (rpm, m<SP>3</SP>/min, m) of 100 or less. The drive shaft 14 is supported by ball bearings 18 and 19, and the moving distance of the drive shaft 14 in the radial direction is lessened. As a result, the clearance between an outer diameter of a suction opening 40 of an impeller 20 and a corresponding inner diameter of a housing 21 becomes 0.2 mm or less, or one thousandth or less of the diameter, alleviating leakage. Reduction in leakage improves pump efficiency.  <P>COPYRIGHT: (C)2003,JPO
