Patent number: 6935638Abstract: A universal substrate holder of the invention for treating wafer substrates in liquids is provided with a shaft and a rod slidingly inserted into the central opening of the shaft. The end of the shaft that protrudes into the bowl supports a base platform for the substrate, while the end of the rod that protrudes into the bowl has radial arms that rigidly support an annular plate with pins that can pass through the opening of the base platform so that they can support the substrate above the surface of the platform. The annular plate supports clamping jaws made in the form of two-arm levers with shorter arms and longer arms. The longer arms are heavier and therefore in the stationary state of the holder keep the jaws turned into an open position. When the shaft begins to rotate, the jaws are turned under the effect of centrifugal forces into positions of clamping the substrate with the shorter arms.Type: GrantFiled: February 21, 2003Date of Patent: August 30, 2005Assignee: Blue29, LLCInventors: Igor C.

Patent number: 5622562Abstract: A process and apparatus for coating a surface of an elongated strip article, e.g. aluminum sheet, with a layer of solid polymer material. The process involves heating the polymer to produce a melt having a viscosity of at least 1000 centipoise when measured according to ASTM D4449 at 1 radian per second, extruding the melt onto a moving surface of the strip article through an elongated slot in a coating head having an extended surface adjacent to the slot arranged at an angle to the moving surface to form a coating gap converging in the direction of movement, thereby forming a coating on the strip article, and pushing the coating head towards the surface of the strip article as the melt is extruded as the coating onto the surface from the slot to reduce the coating thickness to a desired range by pressing the extended surface of the coating head onto the coating as the coating is formed.Type: GrantFiled: May 24, 1995Date of Patent: April 22, 1997Assignee: Alcan International LimitedInventors: Robert A.

Patent number: 5614023Abstract: A method of applying a liquid to a flexible substrate and more particularly to a method in which a magnetic liquid or the like is applied to a flexible area so that a thin liquid film is disposed on the carrier for manufacturing an application-type magnetic recording medium. The method includes positioning carrier and a back edge portion of an application head near each other, discharging the liquid from a slot provided in the head and lapping the carrier and the doctor edge portion of the head, located downstream of the slot, with each other at a predescribed lap angle for the application, and thereafter performing the application. The method further includes moving a path roller which is disposed upstream of the head and to adjust the lap angle, discharging the liquid from the slot of the head and moving the carrier to the head. According a further aspect of the invention, a downstream roller is moved in the direction of the carrier to further adjust the lap angle of the doctor edge portion.Type: GrantFiled: October 26, 1992Date of Patent: March 25, 1997Assignee: Fuji Photo Film Co., Ltd.Inventors: Shinsuke Takahashi, Norio Shibata

Patent number: 5560958Abstract: A method and apparatus for sequentially coating fluorescent lamps with a protective coating. The lamps are advanced continuously through coating apparatus which prepares the surfaces of the lamps for coating, then dips the lamps in a bath of liquid coating material, and subsequently cures the liquid coating material. The lamps may be labeled prior to coating, such that the coating provides tamper resistance for the labeling, in addition to containment of shattered glass and lamp contents in the event of breakage of the lamp.Type: GrantFiled: June 1, 1995Date of Patent: October 1, 1996Assignee: Trojan, Inc.Inventors: Edward F.
