摘要:
A thermal edge finishing process includes preheating at least one cut edge of a glass sheet, laser finishing the edge to a single full continuous radius from a position orthogonal to the edge and in-plane with the glass sheet while continuing to heat the glass, and localized annealing of the edge to reduce residual stress from the laser/thermal treatment of the edge. By the present process, edge stress is reduced considerably, such as to less than 3000 psi, and more preferably to less than 2500 psi, and to as low as 1000 psi in the first 1 mm along the treated edge.
摘要:
An apparatus for edge processing of a glass sheet, the apparatus including a shroud, a finishing member and a wiping device. The finishing member is substantially enclosed by the shroud. The apparatus uses pressurized air emitted by at least one slot in the wiping device to prevent contaminants resulting from the edge processing from settling on and/or adhering to surfaces of the glass sheet. The wiping device may include a jet of washing fluid directed at the glass sheet to further wash the surfaces and the processed edge of the glass sheet.

Disclosed are controlled chemical etching processes used to modify the geometry of surface flaws in thin glass substrates and glass substrate assemblies formed therefrom, and in particular glass substrates suitable for the manufacture of active matrix displays that are essentially free of alkali metal oxides such as Na2O, K2O and Li2O.

Disclosed herein are a high-molecular weight aliphatic polyester, whose molecular weight has been highly increased by a chain-lengthening reaction of a ring-opening (co)polymer of at least one cyclic ester selected from the group consisting of glycolide and lactide with an oxazoline compound, and a production process thereof. The molecular weight of the high-molecular weight aliphatic polyester is highly increased to the extent that a rate of increase in molecular weight represented by a ratio (Mw2/Mw1) of a weight average molecular weight (Mw2) of a ring-opening (co)polymer after the chain lengthening to a weight average molecular weight (Mw1) of the ring-opening (co)polymer before the chain lengthening amounts to at least 1.10.

The present invention is directed to an apparatus for grinding or polishing at least one edge of a glass substrate. The apparatus includes an air bearing support member configured to pivot about an axis of rotation with zero frictional resistance opposing said pivotal movement. A grinding unit is coupled to the air bearing support member. The grinding unit is configured to apply a predetermined force normal to the at least one edge to remove a predetermined amount of material from the at least one edge. The predetermined force is directly proportional to the predetermined amount of material and less than a normal force resulting in glass substrate breakage.

The invention provides a blood treatment apparatus realizing double-step-membrane filtration, namely separation of blood into plasma and a corpuscular fraction and separation of high-molecular-weight substances (e.g. gamma-globulin) in the plasma from low-molecular-weight substances (e.g. albumin). A method of treating blood is also provided.The apparatus and method are effective e.g. in the treatment of blood of patients with peripheral circulatory insufficiency due to arteriosclerosis and of patients with rheumatoid arthritis, which is an autoimmune disease.
摘要:
In an imaging apparatus that records shot video on a first recording medium, extracts a frame image of a desired frame of the shot video recorded on the first recording medium, and records the frame image on a second recording medium and a method for controlling the imaging apparatus, a frame image of a specified frame in the shot video is reproduced and displayed from the first recording medium and, a crop outline of a size selected through an external operation is displayed on the frame image, and the image portion enclosed in the crop outline of the frame image is recorded on the second recording medium.
摘要:
An apparatus and method are described herein which help prevent particles and other contaminants that are generated when an edge of a glass sheet is processed from contaminating or damaging the glass sheet. The apparatus includes an encapsulation device and a processing device. The encapsulation device is capable of supporting two surfaces of a glass sheet. And, the processing device is capable of processing (e.g., cutting, scribing, grinding or polishing) the edge that is adjacent to the supported two surfaces of the glass sheet which are located on a first side of the encapsulation device. The encapsulation device is also capable of substantially preventing particles and other contaminants that are generated when the processing device processes the edge of the glass sheet from reaching the two surfaces of the glass sheet which are located on a second side of the encapsulation device.
