Title: Artificial lawn and filament therefor
Inventor: ISHIKAWA YOSHIO
IPC: D02G3/44
Filed: 1991-12-27
Abstract: PURPOSE:To obtain an artificial lawn capable of preventing a color from sticking to golf balls or others by using filaments made of a synthetic resin having a specific flat cross section and a specific pigment content. CONSTITUTION:The objective artificial lawn is formed by using filaments, having <=3 flatness ratio of the cross section and 0.2-2.0wt.% pigment content and made of a synthetic resin such as polypropylene or Saran(R) as pile yarn and setting the yarn in the form of loop piles or cut piles in a base fabric. Since the filaments have a low flatness degree, the content of the pigment per unit area in the thickness direction (the minor axis direction of the cross section) is increased. Thereby, the pigment with the low content provides coloring effects sufficiently close to those of natural lawn.

IPC: B65H1/26
Filed: 1996-12-09
Abstract: PROBLEM TO BE SOLVED: To prevent the damage of device components when a paper feeding tray is pulled out by erroneous operation by a user. SOLUTION: When a paper feeding tray is pulled out, a fixed gear 19 in a bottom plate rising driving unit 13 rotates, which rotates a lever to push up a bottom plate through a shaft 10 connected to a coupling 18 at an end of a sliding shaft 20 and bumps against the bottom of the paper feeding tray. When the fixed gear 19 rotates further, a sheet loading unit of the paper feeding tray is pushed out by sliding of the sliding shaft 20 and follows a cover unit. When pulling out speed is too fast, a screw unit 44 slides on a gear unit 43 of the fixed gear 19 and the sliding shaft 20 becomes to be movable.  As the screw unit 44 transmits a rotating drive force of the gear unit 43 to the sliding shaft 20 side in spite of its movement, the action of the slide shaft 20 starts lately, a return claw 25 of the coupling 18 is separated from a pin 12 of the shaft 10, and the paper feeding tray can be pulled out.
