IPC: A61M25/18
Filed: 2000-11-15
Abstract: A catheter for use in vasculature or other lumens within body structures includes a shaft formed from an elongated polymeric flexible tube. A thin polymeric sleeve is placed over a proximal portion of the catheter shaft. A hub structure is injection molded over the sleeve with a polymer of the same type as the polymeric sleeve. The heat from the injection molded polymer of the hub body is sufficient to heat the polymeric sleeve, causing the polymeric sleeve to bond the hub body to the sleeve, and the sleeve to the catheter shaft. In this way, the injection molded polymeric hub structure is fused to the catheter shaft, with a unified polymeric bond, and without the use of adhesive. The plastic sleeve is sufficiently thick to protect the catheter shaft from the heat of the injection molded molten polymer while still allowing the catheter shaft and sleeve to bond to the shaft.

Title: Interval measuring method of fuel injector
Inventor: TOYOSHIMA YOSHIO
IPC: F02M65/00
Filed: 2002-01-11
Abstract: <P>PROBLEM TO BE SOLVED: To solve a problem that an expensive measuring instrument using a pressure distribution method must be used in measuring the interval between a pilot injection and a main injection.  <P>SOLUTION: Injection is performed (an interval injection step) during the interval by giving an ON signal to an electromagnetic spill valve from the time when the pilot injection is completed (the start of the interval) to the time when the main injection is started (the completion of the interval). This interval injection quantity Qps is measured by an injection quantity measuring unit (an interval injection quantity measuring step). Next, the interval is converted (a conversion step) from the correlation between the interval injection quantity Qps and the interval. Even when any expensive measuring unit is not used, the interval can be measured by the injection quantity measuring unit such as an inexpensive measuring cylinder. As a result, the cost for interval measurement during the adjustment in shipping can be suppressed. In addition, the interval can be measured even when no expensive instrument is available, and the maintenance including the checking is improved.  <P>COPYRIGHT: (C)2003,JPO
