IPC: B29C65/00
Filed: 1999-04-05
Abstract: PROBLEM TO BE SOLVED: To reduce slide sound generated when a door glass slides in a wet condition. SOLUTION: This glass run 1 is extrusion-molded by an extruder 21 using EPDM rubber and is vulcanized in a vulcanization tank 22. A polyethylene film 12 is bonded on a glass slide face at the stage that a surface temperature is sufficiently high (about 150 deg.C) after vulcanization. The film 12 is melted by heat of the glass run 1 itself. While the film 12 is in a melted condition, polyolefin short fibers are sprayed and planted using an electrostatic powder coating device 23. After that, the polyolefin short fibers pass a cooling tank 23 and are cooled. Since the short fibers jump and fly by pressure of high pressure air and electric charge, they get stuck in the film 12 securely.

Title: Operating lever device capable of extension and contraction
Inventor: ISHIKAWA SHINSUKE
IPC: F16H59/02
Filed: 1983-05-31
Abstract: PURPOSE:To control freely the shaft length for a shift lever of a change gear of a car by permitting the release of an action rod which can move in the axial direction inside the shaft only when the inhibition of shift due to two lock mechanisms is controlled. CONSTITUTION:In an flexible operation mode, a shift lever is first fixed at the lock release position. Then a fixed sleeve 10 and a shaft 20 are revolved round a shaft 14. When the control of a lock plate 62 is released, the shaft 20 and an action rod 30 can move simultaneously toward the upper side of the sleeve 10. Then the engagement is released between racks 54 and 94 and the gears 44 and 80 of two lock mechanisms 40 and 70 at a rise terminal. Thus the shaft 20 and the rod 30 can move downward. At the fall terminal the gears 44 and 80 engage again with each other, and the 1st lock mechanism 40 can permit a free rise of the shaft 20. Thus the length of the shaft 20 is fixed by resetting the shift lever to its normal operation position after the length control.
