Patent CA-2282656-A1 (CA)
Title: N-hydroxy-2-(alkyl, aryl, or heteroaryl sulfanyl, sulfinyl or sulfonyl)-3-substituted alkyl, aryl or heteroarylamides as matrix metalloproteinase inhibitors
Inventor: DAVIS JAMIE MARIE
IPC: A61P17/02
Filed: 1998-02-17
Abstract: Matrix metalloproteinases (MMPs) are a group of enzymes that have been implicated in the pathological destruction of connective tissue and basement membranes. These zinc containing endopeptidases consist of several subsets of enzymes including collagenases, stromelysins and gelatinases. TNF-.alpha. converting enzymes (TACE), a pro-inflammatory cytokine, catalyze the formation of TNF-.alpha. from membrane-bound TNF-.alpha. precursor protein. It is expected that small molecule inhibitors of MMPs and TACE therefore have the potential for treating a variety of disease states. The present invention provides low molecular weight, non-peptide inhibitors of matrix metalloproteinases (MMPs) and TNF-.alpha. converting enzyme (TACE) for the treatment of arthritis, tumor metastasis, tissue ulceration, abnormal wound healing, periodontal disease, bone disease, diabetes (insulin resistance) and HIV infection. The compounds of this invention are represented by formula (I), where R1, R2, R3 and R4 are described herein.

Patent CA-2288438-A1 (CA)
Title: Process for producing ceramic powders, especially titanium dioxide useful as a photocatalyst
Inventor: VEMURY SRINIVAS
IPC: C01G19/02
Filed: 1995-08-25
Abstract: A gas phase process for the production of titanium dioxide powders having well-controlled crystalline and surface area characteristics is disclosed. In this process, which is preferably carried out in a laminar diffusion flame reactor, vapor phase TiCI4 and oxygen are mixed in a reaction area which is heated externally. The titanium dioxide powder formed is then collected. It is preferred that the heat source used be a hydrocarbon fueled (e.g., methane) flame. Optionally, a vapor phase dopant (such as SiCl4) may be added to tire reaction mixture to desirably affect flee physical properties of the titanium dioxide produced.  In a particularly preferred embodiment, a corona electric field is positioned across the area where the combustion reaction takes place (i.e., the reaction area). High anatase, high surface area titanium dioxide powders made by this process are excellent photocatalysis.  The products of this process and the use of those products as photocatalysis are also disclosed. This process is also useful for producing other ceramic powders (such as silicon dioxide and tin oxide), as well as pure metallic or alloy powders.

Title: Video camera
Inventor: TOMINAGA HIDETO
IPC: H04N5/225
Filed: 1999-11-04
Abstract: A video camera includes an abutment piece which is perpendicularly placed on the anterior side of the bottom of a stand portion and abuts on an attachment body to which the video camera is to be attached, a lever portion which is rotatably attached on the posterior side of the bottom of the stand portion, and bias means for biasing the lever potion toward the bottom of the stand portion. The lever portion includes an abutment portion formed such that it abuts on the abutment body. The lever portion holds the attachment body between the abutment portion and the abutment piece when it is used, and is housed in the stand portion such that it is pressurized to abut on the stand portion when it is not used.    This structure enables the video camera to easily be attached to and detached from various attachment bodies such as flat display that are different from each other in thickness. When the video camera is detached from the body, the lever portion is compactly housed and accordingly the video camera can be placed directly on a flat surface for use.

Title: Fine protuberance structure and method of production thereof
Inventor: WAKAYAMA YUTAKA
IPC: H01L29/06
Filed: 1998-11-27
Abstract: A fine particle of metal is disposed on a semiconductor substrate. With the exception of a position of disposition of the fine particle of metal, a covering layer is formed on a surface of the semiconductor substrate. Thereafter, heat treatment is implemented at a temperature higher than that where constituent atoms of the semiconductor substrate and constituent atoms of the fine particle of metal dissolve at an interface thereof due to interdiffusion in a vacuum atmosphere. Thus, a fine projection structure that comprises a semiconductor substrate and a fine projection consisting of a solid solution of the semiconductor substrate and the metal is obtained. The fine projection is formed with part thereof precipitating in the semiconductor substrate. The fine projection structure as this largely contributes in realizing high integration semiconductor devices and quantum size devices.
