Title: Exposing device
Inventor: ASANO MASAAKI
IPC: H01J17/49
Filed: 1997-12-19
Abstract: PROBLEM TO BE SOLVED: To provide an exposing device for forming a phosphor screen of a plasma display panel that can ensure exposing accuracy and that does not damage on a work substrate or a photo mask. SOLUTION: A support member 14 that supports only a bottom surface of a photo mask 13 is used for a member to move up and down supporting both sides of the photo mask 13. As the photo mask 13 is only placed on a work substrate 11 if a relative position between the support member 14 and the work substrate 11 is changed, exposure can be performed in a state that there is no clearance between them. Damage on the photo mask 13 is avoided by means of a cushion operation of a film by inserting the film between the work substrate 11 and the photo mask 13. Also, exposure can be performed without clearance between the work substrate and the photo mask 13 by providing a transparent pressing member to press the photo mask 13 to the work substrate 11.

IPC: B60T13/12
Filed: 1999-12-13
Abstract: PROBLEM TO BE SOLVED: To provide a hydraulic booster capable of improving durability while surely accumulating prescribed fluid pressure in an emergency accumulator. SOLUTION: When accumulating pressure of an emergency accumulator 9 is not more than preset pressure, a first ball valve 111 separates from a first seat part 108, a second ball valve 112 sits on a second seat part 109, and the accumulating pressure of the emergency accumulator 9 is introduced to a chamber 101 to act on a stepped piston 7. Thus, since a flow restriction valve 68 restricts a flow of a hydraulic fluid from a pump 6, fluid pressure is generated, and the generated fluid pressure is accumulated in the emergency accumulator 9. At this time, since a pressing surface 115a of a second pressing member 115 for pressing the second ball valve 112 is formed as a flat surface, the second pressing member 115 presses the second ball valve 112 only in the shaft direction.  Thus, the second ball valve 112 closely and surely sits on the second seat part 109 without partial loading by eccentricity.
