Title: Method for manufacturing liquid ejection head
Inventor: MATSUNO YASUSHI
IPC: B41J2/045
Filed: 2002-01-09
Abstract: <P>PROBLEM TO BE SOLVED: To provide a method for manufacturing an ink jet head in which an ink supply chamber shallower than an ink pressure chamber can be formed without increasing the number of manufacturing stages.  <P>SOLUTION: On the surface of a silicon substrate 2A for forming an ink jet head, an ink pressure chamber and an ink supply chamber are formed by wet anisotropic etching. A mask pattern 31a covering the surface part for forming an ink supply chamber recess 18 in the silicon substrate 2A includes a large number of rhombic openings 41 formed discretely and the mask pattern 31a is stripped and removed automatically utilizing undercut progressing from the four sides 42-46 of each rhombic opening 41 as etching progresses. Etching progresses at a lower rate in the part for forming the ink supply chamber recess as compared with the ink supply chamber side until the mask pattern 31a is removed, and progresses at the same rate after the mask pattern a is removed. Consequently, an ink supply chamber shallower than the ink pressure chamber can be formed simultaneously by single patterning process and single etching process.  <P>COPYRIGHT: (C)2003,JPO

Filed: 2002-01-29
Abstract: <P>PROBLEM TO BE SOLVED: To provide a seal packing 1 which is low in reaction force and high in compression, and hardly causes permanent set in fatigue of rubber.  <P>SOLUTION: A packing mounting groove 4 is formed on a body 2 side of an air cleaner, and a seal wall portion 5 is formed on a cover 3 side. The seal packing 1 made from solid rubber has an approximately U-shaped section including a center wall portion 11 receiving the seal wall portion 5 and both side leg portions 12, 13, and is formed in an continuous shape of endless frame in advance. With the seal packing 1 mounted in a packing mounting groove 4, a tip of the leg portion 12 is brought into press-contact with a tip of the leg portion 13 to constitute a hollow portion on a back face side of the central wall portion 11. Since the seal wall portion 5 presses a center portion of the central wall portion 11, the seal wall portion is easily deformed by the presence of the hollow portion, so that the seal wall portion is low in reaction force and high in compression. Air sealed in the hollow portion gives restoring force to the seal wall portion, and the permanent set in fatigue is suppressed.  <P>COPYRIGHT: (C)2003,JPO
