Title: Method of forming a swimming pool construction
Inventor: HABERLER GERHARD
IPC: E04H4/02
Filed: 2001-09-17
Granted: 2008-01-29
Abstract: A swimming pool construction is of the type using metal fabricated walls and a plastics liner covering the walls and a rigid excavated pool base. The metal fabricated walls include spaced inner and outer panels defining therebetween a crawl space. The inner panels define the inner surface of the pool, The outer panels engage the surrounding soil. The panels are mounted on support members and rails supported on pairs of piles at spaced positions around the periphery of the pool. The panels are supported initially on bottom rails which are used as forms to cast a concrete layer therebetween. The panels are supported in spaced positions temporarily by a rigid arch form into which is cast a cast concrete arch allowing the rails and the arch form to be removed for re-use. The arch is cast integrally with a concrete floor which sits on supporting panels bridging the rails and resting on flat top supporting surfaces of the concrete piles. A top concrete cover is cast onto bridging panels spanning between the inner and outer walls and carried on the top of the arches.

Title: Epitaxial thin films
Inventor: HWANG TZYY-JIUAN JAN
IPC: H01L49/02
Filed: 2000-01-12
Granted: 2008-09-02
Abstract: Epitaxial thin films for use as buffer layers for high temperature superconductors, electrolytes in solid oxide fuel cells (SOFC), gas separation membranes or dielectric material in electronic devices, are disclosed. By using CCVD, CACVD or any other suitable deposition process, epitaxial films having pore-free, ideal grain boundaries, and dense structure can be formed. Several different types of materials are disclosed for use as buffer layers in high temperature superconductors. In addition, the use of epitaxial thin films for electrolytes and electrode formation in SOFCs results in densification for pore-free and ideal grain boundary/interface microstructure. Gas separation membranes for the production of oxygen and hydrogen are also disclosed. These semipermeable membranes are formed by high-quality, dense, gas-tight, pinhole free sub-micro scale layers of mixed-conducting oxides on porous ceramic substrates. Epitaxial thin films as dielectric material in capacitors are also taught herein. Capacitors are utilized according to their capacitance values which are dependent on their physical structure and dielectric permittivity. The epitaxial thin films of the current invention form low-loss dielectric layers with extremely high permittivity. This high permittivity allows for the formation of capacitors that can have their capacitance adjusted by applying a DC bias between their electrodes.

Title: Valve operating control system in engine
Inventor: KOBAYASHI TOSHIKI
IPC: F01L13/00
Filed: 2001-10-24
Granted: 2005-08-16
Abstract: A pair of valve-timing controlling oil passages leading to a second valve-operating characteristic changing mechanism are defined in a lower camshaft holder, and a valve lift controlling oil passage leading to a first valve-operating characteristic changing mechanism is defined between the pair of valve-timing controlling oil passages in a mating surface of the lower camshaft holder with a cylinder head. In an area where the width of the valve lift controlling oil passage is reduced in order to avoid the interference with the valve-timing controlling oil passages, the depth of the valve lift controlling oil passage is larger than that in the other positions, whereby a sectional area of the oil passage is secured. Thus, the oil passages leading to the first and second mechanisms can be formed compact in a camshaft support member.

Abstract: Le principe du procédé et du système de mesure selon l'invention est de mesurer des champs électriques pour déterminer les caractéristiques électriques des phases dans un mélange multiphase constitutifs d'un flux de fluide dans un conduit. Cela intervient pour une partie de l'évaluation des fractions des phases. De plus, on utilise des signaux variant dans le temps provenant d'une paire au moins de détecteurs réagissant aux caractéristiques du fluide, et on a alors recours à une corrélation croisée permettant de déterminer l'une au moins des vitesses affectant le fluide du flux. En outre, on mesure une chute de pression au moins, de part et d'autre ou au voisinage d'un étranglement. En combinant les mesures des caractéristiques électriques aux mesures des chutes de pression, on arrive à déterminer les fractions de toutes les phases du flux. En combinaison avec les mesures de vitesse, on calcule les débits volumiques d'écoulement correspondant aux phases, et ensuite, en combinant cela avec les densités massiques des phases, on arrive à calculer le débit d'écoulement massique des phases.

Title: Optical element such as multilayer film reflector, and the like, method of manufacturing the same, and apparatus using the same
Inventor: YAMAMOTO MASAKI
IPC: G21K1/06

Granted: 2009-12-08
Abstract: A multilayer film reflector capable of simply correcting a wavefront phase and a method of forming the reflector are disclosed. For this purpose, a reflector using reflection by a multilayer film is disclosed. This multilayer film is formed in a number of cycles larger than that necessary to substantially saturate a reflectance, and a wavefront phase of emerging rays is adjusted by cutting away the multilayer film in accordance with an amount of adjustment of the wavefront phase. Further, the formation of a correction film as well as the formation of a multilayer larger than necessary to substantially saturate the reflectance permits the correction of a phase by cutting away also the multilayer film when the phase cannot be corrected only by cutting away the correction film, whereby the phase can be corrected more accurately.

Abstract: A more efficient message notification system utilizing technology found in Instant Messaging Services. The more efficient system is achieved by first registering a Message Notification Application with an Instant Messaging Service. A user logs onto the Instant Messaging Service and indicates to the Message Notification Application that the user would like to be notified when new messages arrive. The Message Notification Application then adds the user to its own buddy list. The user is notified by the Message Notification Application through the Instant Messaging Service when a message is received. The user can then retrieve messages through an internet appliance with sound capabilities, or by utilizing the voice-to-text conversion capabilities of the application form the voice messaging or unified messaging server, or by more traditional methods such as a telephone.

Abstract: A wood screw is provided which can be smoothly driven in with a small driving force. Helical ribs that are the highest at the center and gradually lower toward both ends are formed on the outer periphery of the tip of a shank having threads on the outer periphery at intervals of 1800 in the circumferential direction. Each helical rib is a discontinuous body formed by a plurality of protrusions having different heights. This reduces the turning resistance imparted to the helical ribs, thereby reducing the driving force required.

Title: Method for compression and decompression of image data
Inventor: MOSSAKOWSKI GERD
IPC: H04N19/593
Filed: 2002-03-19
Granted: 2012-10-09
Abstract: The invention relates to a method for compression and decompression of pixel-based image data. Each pixel first has the pixel value determined. A pixel difference value is then determined for each pixel, from a given number of neighbouring pixels, which results from the difference in the pixel value for the pixel in question to each of the neighbouring pixels thereof. The pixel difference values are then sorted in descending order. Each pixel used for the calculation of a pixel difference value is assigned to a pixel group. The pixel groups obtained thus are stored according to the descending sorting of the pixel difference values. For regeneration of the image the pixel groups with the highest pixel difference values are first loaded. A triangle is formed from the three closest pixel groups. The surfaces of each triangle are filled in a colouring process, calculated from the colour values of the pixel groups forming each of the three corners of the triangle. The more pixel groups are loaded the smaller the triangles become and the more precise the reconstruction of the image.
