Title: Proton conduction material and method of manufacturing the same
Inventor: ARAI TAKUICHI
IPC: H01M8/10
Filed: 2003-11-03
Abstract: A proton conduction material having high proton conductivity and exhibiting high reactive gas permeability regardless of the percentage of water content is provided. This proton conduction material consists of a polymer material whose molecular structure has a strong acid functional group. This polymer material consists of a polymer of a mixture of a monomer having an end structure expressed by a formula (1) or a vinyl radical and a monomer expressed by a formula (2). (see formula I and II) A strong acid functional group is included in the structure of both the monomers. It is to be noted herein that R1, R2, R3, R4, R5 and R6 represent a hydrocarbon radical, a fluoro-substituted hydrocarbon radical, or a trimethylsiloxy radical. Because introduction of a structure in which a hydrocarbon radical is bonded to silicon weakens interaction and causes bulkiness, gaps are created among atoms. If the number of the gaps among the atoms increases, the diffusion coefficient of reactive gases increases. As a result, permeability of the reactive gases can be enhanced.

Title: Emulsified polymer drilling fluid and methods of preparation and use thereof
Inventor: WU AN-MING
IPC: C09K8/28
Filed: 2003-12-01
Abstract: A water-based polymer drilling fluid, containing effective quantities of surfactants having HLB numbers equal to or greater than approximately 7, emulsifies oil and bitumen contained in oil sand cuttings, resulting in the oil and bitumen being dispersed into the mud as an emulsion. This eliminates or significantly reduces the ability of the oil, bitumen, and cuttings to clog the well or stick to drill string components when drilling a well through oil-bearing sands, particularly sands containing highly viscous oil or bitumen. The emulsification process separates the sand particles from the oil and bitumen, such that the sand particles can be removed when the mud is run through a conventional shale shaker or other suitable apparatus.

Abstract: La présente invention concerne un procédé et un dispositif destinés à l'ablation thermique ou à la coagulation de tissus biologiques à moyen d'un faisceau laser à balayage sous surveillance vidéo en temps réel et surveillance des paramètres de traitement thérapeutique, tels que la température avant ou pendant le traitement (figure 1). Dans un mode de réalisation préféré de l'invention, un unique système de diffusion optique réfléchissant est utilisé en même temps que s'effectue la régulation de la température dans la zone de traitement (18, 20 et 22), et, éventuellement, le traitement cryogénique de la zone de traitement permettant d'éliminer ou de réduire l'utilisation de produits anesthésiants. Tous les paramètres thérapeutiques peuvent être affichés sur un moniteur vidéo (26) qui est relié à un dispositif de balayage laser (10). Les optiques réfléchissantes du dispositif de balayage laser permettent d'obtenir une vaporisation monocouche précise de la part du laser, sans que les tissus sous-jacents soient sujets à des lésions thermiques, et le moniteur vidéo permet à un chirurgien de suivre les paramètres thérapeutiques à la fois avant et pendant une procédure de traitement. Le moniteur vidéo peut également fournir une représentation tridimensionnelle de la zone de traitement. Ceci peut aussi faire l'objet d'un enregistrement vidéo à des fins de documentation.

Title: Air pump assembly for ventilative footwear
Inventor: PARK KWANG-SEUK
IPC: A43B17/08
Filed: 2001-11-12
Abstract: Disclosed is an air pump assembly for ventilative footwear, in which the air pump assembly is mounted onto a heel portion of an outsole, so that external air is forcibly introduced into an interior of a shoe when walking, thereby cleaning the interior of the shoe and providing a pedestrian with a cushion function. If the air pump assembly is compressed by the compression force, the bending portion is smoothly bent along the resilient ring, while if the compression force is released, the rigid plate the bending portion is naturally restored. Accordingly, the fatigue of the bending portion due to the repeated retraction is reduced, thereby preventing the rupture of the assembly and thus extending its life.

Abstract: A method of manufacturing a printed, laminated pickup truck bed and bed liner includes the steps of forming by extrusion or another process a single or double layer substrate of a desired thickness and strength. If a single layer, it will preferably be formed of a thermoplastic material such as high density polyethylene (HDPE). If a double layer, the lower layer may be HDPE or HDPE reinforced with random fibers or a fibrous material to improve its strength and ruggedness. Additionally, a cast or blow film upon which may be printed a desired pattern such as, for example, camouflage or indicia, is utilized as the top layer of the material. The two or three layers are laminated together either with or without the use of an adhesive and then formed into a bed or bed liner by a thermoforming process.

Abstract: A viscosity and viscoelasticity measuring instrument (10) has a cam (20), a follower arm (22), a flat spring (24), a plate fixture (28), and a removable plate assembly (30). The cam is a rotating circular disk with a spiral slot (34). A cam follower (60) on the follower arm (22) resides in the spiral slot (34) so that the follower arm (22) pivots about its fixed end (56) as the cam (20) rotates. The spring (24) is attached to and collinear with the fixed end (56) of the follower arm (22) so that the spring (24) pivots in the opposite direction as the follower arm (22). The removable plate assembly (30) has a lower plate (102) and an upper plate (104) with mating sample surfaces (114, 128) on which test fluid is placed. The lower plate (102) fits into a lower jaw (86) of the plate fixture (28) that is attached to the instrument base (12). The upper plate (104) fits into an upper jaw (90) of the plate fixture (28) attached to the free end (74) of the spring (24). A fluid is placed on the lower sample surface (114). The cam (20) rotates, pushing the follower arm (22) up, causing the spring (24) to pivot down, and pressing the sample surfaces (114, 128) together. The cam (20) is reversed, causing the spring (24) to impart a separation force to the plates (102, 104). The time it takes for the plates (102, 104) to separate is measured and converted to a viscosity value.
