Title: Recording liquid feeding device and image forming apparatus
Inventor: HIRUMA TETSUYA
IPC: B41J2/175
Filed: 2003-11-11
Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that a recording liquid leaks from a feeding route to cause breakage or the like of a driving mechanism when a pump is driven while an overload is kept applied to a piston of the pump because a fluid resistance of the recording liquid increases due to a viscosity increase of the recording liquid such as a high-viscosity recording liquid, and to a temperature change.  <P>SOLUTION: The piston 203 is fitted in a cylinder 201 to be freely slidable. A cam 214A is set, which contacts a piston rod 215A with the cylinder 201 and the piston 203 mounted thereto. The rotation of a motor 211 is transmitted from a worm gear 212 to a worm wheel 213. The cam 214A is rotatably set at an axial part 231A of the worm wheel 213. A spring 232A is fitted at the axial part 231A to have its one end secured to the cam 214A, whereby a driving force can be transmitted to the cam 214 in only one direction. At the same time, a rotation force in one direction cannot be transmitted at all if a predetermined or larger braking force is applied to the cam 214A.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To improve a structure of a gundrill such that the gun drill can drill a variety of products made of metals from relatively brittle cast iron to soft and ductile aluminum.  <P>SOLUTION: A method for forming a deep hole and a gundrill therefore is disclosed. The gun drill has a tubular shank 200 and a cutting tip. They are provided with a tubular central region 210 for supplying pressurized drilling fluid and a non-circular cross section 232 defining a drilling fluid return passage together with a hole being formed.
