Appl. No.:

10/059536

Inventors:

Dong-Hun Kang - Pusan, KR
Young J. Choi - Oakland NJ

Assignee:

Komelon Corporation - Pusan

International Classification:

B65H 7548

US Classification:

2423812, 2423813, 33767

Abstract:

Disclosed herein is a tape locking device for tape measures. The tape locking device comprises a locking lever hinged to an upper portion of the wall of the housing in such a way to be rotated frontward and rearward around a hinged joint, and provided with a connecting piece downwardly extending from the locking lever. A cylinder is connected at its first end to a hole formed at the lower portion of the connecting piece, with a coil spring fitted over the cylinder. A wedge-shaped stopper is connected to the second end of the cylinder, and having a desired frictional force. This stopper is elastically biased by the coil spring to be wedged in the gap between the outer circumferential surface of a wound part of the tape around the bobbin and a linear part of the tape led to the slot when releasing the locking lever after drawing a desired length of tape from the slot, so the drawn tape is automatically locked by frictional contact between the stopper surface and the drawn tape surface.

Abstract:

A tape measure includes an automatic blade extension mechanism. The tape measure allows a user to draw and lock a blade using only one hand, when measuring a dimension of an object, thus allowing the other hand to be freely used in a workplace where several operations must be carried out. Therefore, the tape measure allows the user to simultaneously perform a cutting operation, a hammering operation, a marking operation, etc. during the measuring operation. Thereby, the tape measure of this invention is convenient to use, and increases work efficiency.

International Classification:

C23C 16/00
H01L 21/306

US Classification:

118715, 15634531, 15634532

Abstract:

The present invention generally comprises a method and an apparatus for guiding the flow of processing gases away from chamber walls and slit valve opening. By controlling the flow path of the process gases within a processing chamber, undesirable deposition upon chamber walls and within slit valve openings may be reduced. By reducing deposition in slit valve openings, flaking may be reduced. By reducing deposition on chamber walls, the time between chamber cleaning may be increased. Thus, guiding the flow of processing gases within the processing chamber may increase substrate throughput.

Abstract:

A head shade comprises a shade fabric stretched over a collapsible set of bow frames. These all join externally at bow pivots on the left and right sides that are at ear height. The shade and bows can all be folded back out of the way. Interior to each bow pivot, loudspeakers are included that allow the user to listen to music and other audio. The bow pivots are fastened to the tops of left and right stems. Such stems are attached by adjustable hinges to a shoulder yoke and body straps. The straps are anchored to a belt worn around the waist of the user to stabilize the stems and bow pivots.

US Classification:

216 67, 118715, 4272481, 427569, 15634535

Abstract:

The present invention generally includes a chamber liner spaced from a chamber wall to permit processing gases to be pulled between the chamber liner and the chamber wall when withdrawing gases from the processing chamber. When the vacuum pump is below the susceptor, processing gases will be drawn below the susceptor and may lead to undesired deposition onto process chamber components. Additionally, the processing gases will be pulled past the slit valve opening and potentially deposit within the slit valve opening. When material deposits in the slit valve opening, flaking may occur and contaminate the substrates. By drawing the processing gases along the sidewalls other than the one having the slit valve opening therethrough, undesired deposition on the slit valve opening may be reduced.

International Classification:

C23C 16/54
F28D 7/00

US Classification:

118723 R, 165164

Abstract:

The present invention generally includes a coupling between components. When igniting a plasma remote from a processing chamber, the reactive gas ions may travel to the processing chamber through numerous components. The reactive gas ions may be quite hot and cause the various components to become very hot and thus, the seals between apparatus components may fail. Therefore, it may be beneficial to cool any metallic components through which the reactive gas ions may travel. However, at the interface between the cooled metallic component and a ceramic component, the ceramic component may experience a temperature gradient sufficient to crack the ceramic material due to the heat of the reactive gas ions and the coolness of the metallic component. Therefore, extending a flange of the metallic component into the ceramic component may lessen the temperature gradient at the interface and reduce cracking of the ceramic component.

Abstract:

Embodiments disclosed herein generally include methods of ensuring uniform deposition on a substrate. The smallest gap between a portion of the substrate and the substrate support upon which the substrate rests may lead to uneven deposition of material or ‘thin spots’ on the substrate. Large area substrates, due to their size, are susceptible to numerous gaps at random locations. By inducing an electrostatic charge on the substrate prior to placing the substrate onto the substrate support, the substrate may be placed generally flush against the substrate support. The electrostatic charge on the substrate creates an attraction between the substrate and substrate support to pull substantially the entire surface of the substrate into contact with the substrate support. Material may then be substantially uniformly deposited on the substrate while reducing ‘thin spots’.
