Abstract: <P>PROBLEM TO BE SOLVED: To provide a sealing plate for an EL device which has sufficient strength to external pressure and is capable of effectively preventing moisture and oxygen from infiltrating into the EL device, and also provide a multiple sealing plate-producing mother glass substrate and the EL device.  <P>SOLUTION: A multiple sealing plate-producing mother glass substrate 100 has sealing plates for an EL device formed in a matrix shape of 5 by 6 using a wet etching method. In a wet etching method, a starting material glass plate having a thickness of 0.7 mm is masked in a matrix shape of 5 by 6 using a tape-like resist of 2.0 mm wide. The masked starting material glass plate is then immersed in a prepared etching solution, whereby glass is removed from the starting material glass plate to form recessed parts 102 at the exposed parts, leaving behind projecting parts 101 at the masked parts. The starting material glass plate is next washed thoroughly with pure water, and then the resist is stripped off. Next, the multiple sealing plate-producing mother glass substrate 100 in which the recessed parts 102 have been formed in a 5 by 6 matrix shape is cut along the projecting parts 101 that partition the recessed parts 102 from one another. As a result, 30 (5 by 6) EL device sealing plates having a width of not less than 0.7 mm at the peripheral projecting parts are obtained.  <P>COPYRIGHT: (C)2004,JPO

Title: Sealing device
Inventor: NAGASHIMA MASAMICHI
IPC: F16C33/78
Filed: 2002-06-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide a sealing device capable of prolong a service life by preventing the rise of a pressure on a sealed side.  <P>SOLUTION: A temperature on the inside I of a bearing 10 on the inside I is raised by an operation by communicating the inside I with an outside O through first to third grooves 13, 14, and 15. When the air inside I is thermally expanded, the air is discharged to the outside O. Accordingly, the rise of an internal pressure is not produced by the thermal expansion of the air on the inside I. Thus, the heating temperature of a seal lip 6 is not raised by the rise of the internal pressure, and the deterioration of rubber material and the wear of the lip thereof are not advanced. As a result, the cause of shortening the service life of the sealing device 1 can be eliminated to prolong the service life of the sealing device.  <P>COPYRIGHT: (C)2004,JPO
