Title: Locking structure for binder
Inventor: KANEDA KATSUMI
IPC: B42F13/16
Filed: 2000-07-26
Granted: 2001-06-23
Abstract: In a conventional binder, a rotating shaft (16) for an end (14) of plural binding rings (12) fixed at an interval along a longitudinal direction is accommodated rotatably and slidably in a sheath part (20) provided at the long side of the base (18). The rotating shaft (16) moves along the axial direction to allow open/close by countering the deviating force of spring members (26, 29). Because there is no locking, a binder with this structure has the disadvantage that the binding ring can be opened easily by an external force. In this invention, a locking member is installed. A pawl member (38) is provided on the rotating shaft (16) to lock the end of the sheath part (20) while the binding ring is at a closed state. A push member (32) is pushed by fingers from a closed state to counter the deviating force in the axial direction and move along the axial direction to release the locking of the pawl member (38).

Title: Method for reducing generation of dynamic false contour phenomenon on plasma flat display and its device
Inventor: LAI YUE-HUNG
IPC: G09G3/28
Filed: 2001-08-22
Granted: 2003-02-01
Abstract: The present invention provides a method for reducing generation of dynamic false contour phenomenon on plasma flat display and its device. When a plasma flat display displays each field of dynamic image, the same input gray level to be displayed by each discharge unit on the continuous dynamic field can be converted into the same gray level value of different vision center series by a vision center conversion table. Therefore, in the process of continuously displaying dynamic fields, the discharge unit corresponding to each sub-field of every dynamic field can present desired same gray level based on the continuous illuminating numbers corresponding to gray level of different vision center series. Accordingly, the vision centers of different gray levels presented by two adjacent discharge units on each dynamic field are respectively averaged and mixed as a gray level with a relative small vision center difference, thereby effectively solving the generation of dynamic false contour phenomenon due to a large difference between the vision centers of gray levels of two adjacent discharge units.

Title: Apparatus and method for reducing contamination on thermally processed semiconductor substrates
Inventor: ROTERS GEORG DR
IPC: C23C16/44
Filed: 2001-09-12
Granted: 2003-01-01
Abstract: In an apparatus and a method for thermal processing semiconductor substrates, such as semiconductor wafers, a reaction chamber for processing each substrate with a reactive gas when the substrate is held within the chamber is provided. At least one element forming part of the chamber or associated with the chamber, and which will contact the reactive gas(es) used for thermal processing, is constructed of a metal that is coated with a silicon or silica-containing layer. The primary silicon or silica-coated metals used are stainless steel or aluminum or an aluminum alloy. It has been found particularly advantageous to coat stainless steel reaction chamber inlet and exhaust flanges and associated tubing with the silicon or silica-containing layer to a coating thickness greater than about 1000 Å, and preferably in the range of 1200 Å to 4800 Å, using a chemical vapor deposition (CVD) process at a temperature in the range of 300-400 DEG C for stainless steel and 200-600 DEG C for aluminum. The use of silicon- or silica-coated stainless steel reduces metal corrosion that could occur when the flanges and tubing contact reactive gases, such as steam, and also thereby reduces or eliminates contamination, such as iron and iron oxide contamination, on the semiconductor substrates thermally processed with the reaction gases within the reaction chamber.

Thereby, the shapes of the apertures can be made to be uniform over the entire surface in a state in which the shadow mask is stretched. As a result, a cathode ray tube with less color unevenness can be provided.
