Title: Piston ring structure of internal combustion engine
Inventor: MINAMI KATSUYA
IPC: F02F5/00
Filed: 2008-04-17
Abstract: <P>PROBLEM TO BE SOLVED: To achieve both of a function of not scraping up oil in the up stroke of a piston and a function of scraping down the oil in the downstroke of the piston.  <P>SOLUTION: A piston ring is constituted by an outer ring 16 received by a ring groove provided on a piston 3, and a plate expander 17, and a friction material 18 with a high coefficient of friction is applied to a part where a bottom surface 13a of the ring groove and the plate expander are abutted with each other. The hysteresis due to the influence of the friction material is generated in tension variation of the expander between the up stroke and the downstroke of the piston. Therefore, the outer ring is energized by increase of the tension of the expander and the oil scraping down performance is enhanced during the downstroke of the piston, and the oil is prevented from being scraped up by reduction of the tension of the expander compared to the time of the downstroke during the up stroke of the piston, and flow-in of the oil to a combustion chamber is reduced, and an oil consumption amount is reduced.  <P>COPYRIGHT: (C)2010,JPO&INPIT

IPC: E04G21/12
Filed: 2008-05-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a braking device for a wire reel in a reinforcing bar binding machine and its brake handling method for improving brake performance.  <P>SOLUTION: In this brake handling method, a CPU stops operation of a feed motor at step 110 when the number of rotation of a feed gear reaches the reference number when step 108 is YES. Here, a solenoid is turned on immediately before the completion of wire feeding because time lag until brake is applied on the wire reel from the operation of the solenoid is taken into account. That is, since braking is started by a stopper device for the rotation of the wire reel after a wire is fed by the predetermined amount of feed before reaching the predetermined length by the feed gear, the time lag caused when braking the wire reel can be reduced, and brake performance is improved.  <P>COPYRIGHT: (C)2010,JPO&INPIT
