IPC: F02M25/06
Filed: 1977-12-20
Abstract: PURPOSE: To reduce NOx, by mounting a pressure feeder and an orifice to a back pressure control system exhaust gas recirculation device.  
     CONSTITUTION: A pressure feeder 40, which volume varies in response to the negative pressure of an intake system manifold, is arranged to a pressure transmission passage 36 for transmitting exhaust gas pressure to a relief valve 30, and an orifice 50 is installed to the exhaust gas control valve 10 side from a branch point of the relief valve 30 and the pressure feeder 40.

Title: Polyester fiber winding method
Inventor: OKA KENICHIROU
IPC: B65H54/02
Filed: 1983-08-25
Abstract: PURPOSE:To reduce the inner distortion depending on the winding position and the aging of thread quality, by employing specific reciprocation speed and winding speed of spindle in a spindle drive winder where the package under winding is made contactless against others. CONSTITUTION:The winding speed must be higher than 5,000m/min, preferably higher than 5,500m/min, where the thread produced through high speed spinning has such inner structure as crystal orientation fc>=0.85 while non-crystal orientation fa<=0.5 and since the inter-molecular bonding at the crystal portion is strong, it can be used practically as it is. While since distortion is not provided under winding and the distortion is not different depending on the position, a spindle-drive type winder is employed to wind under completely contactless state. Assuming the winding speed is V(m/min) while the speed of spindle mounted with a bobbin is T(cm/sec), it is reciprocated while satisfying the relation V/ 2,400<=T<=V/180 to form a package 15. Consequently, the thread path to be wound over the bobbin will never move as traverse motion but travel on substantially constant position.
