|20150240950||Bellows Seal - In an embodiment, a bellows seal is characterized by having a bellows||08-27-2015|
|20150184753||Mechanical Seal - A mechanical seal having a seal cover that has a high versatility and is less prone to deformation even when secured to a housing by two bolts is provided. A mechanical seal||07-02-2015|
|20140091530||MECHANICAL SEAL - An inside-type mechanical seal is mounted between a rotating shaft and a housing, and adapted for preventing leakage of a sealed fluid from an outer circumference of a sliding surface in the direction of an inner circumference thereof, wherein provided are a rotary-side sealing ring mounted on a rotating shaft side, a stationary-side sealing ring mounted on a seal case side, an annular packing for pushing the stationary-side sealing ring toward the rotary-side sealing ring, a holding part on the outer circumferential side being fitted in the seal case, and a seal lip part on the inner circumferential side being in close contact with the stationary-side sealing ring, and wherein provided to the seal case is a ring-shaped projection abutting against a back surface of the packing during assembly of the mechanical seal, and adapted for pushing the packing toward the stationary-side sealing ring.||04-03-2014|
|20140082906||WELDED BELLOWS FOR SEMICONDUCTOR MANUFACTURING DEVICE - An accordion-structured welded bellows for a semiconductor-manufacturing device is characterized in that a plurality of annular bellows plates having curved surfaces in a radial direction are connected in an alternating fashion on the outside-diameter side and the inside-diameter side, wherein the annular bellows plates have a processing-side bellows plate and a non-processing-side bellows plate, a gas layer is interposed between the two bellows plates, the processing-side bellows plate is configured as a thick plate, and the non-processing-side bellows plate is configured as a thin plate. The welded bellows is less likely to be damaged by foreign matter and to be able to use the non-processing-side bellows plate to compensate for any damage to the processing-side bellows plate.||03-27-2014|
|20140035236||SEMICONDUCTOR FABRICATION DEVICE WELDED BELLOWS - A semiconductor fabrication device welded bellows of an accordion structure is characterized in that a plurality of annular bellows plates having faces curving in a radial direction are connected alternatingly at the outside diameter side and inside diameter side, wherein the annular bellows plates are provided with a treatment-side bellows plate and a non-treatment-side bellows plate, a gas layer disposed between the two bellows plates, the treatment-side bellows plate being of lesser thickness, and the non-treatment-side bellows plate being of greater thickness. The bellows are highly resistant to damage caused by foreign matter; or, in the unlikely case that the treatment-side bellows plate becomes damaged, the damage can be compensated for by the non-treatment side bellows plate.||02-06-2014|
